The result is a creamy, cheesy filling with a lightly browned top that looks impressive without requiring complicated preparation.
This recipe is ideal for fall dinners, Thanksgiving gatherings, Christmas meals, or simple weeknight cooking. The ingredients are easy to find, the preparation is straightforward, and the finished dish pairs well with roasted chicken, grilled steak, or a crisp green salad.

Ingredients for Twice Baked Butternut Squash
This recipe relies on a handful of simple ingredients. Each one contributes to the flavor or texture of the finished dish.
1. Butternut Squash
You’ll need 1 medium butternut squash, halved lengthwise with the seeds removed.
Butternut squash has a naturally sweet, nutty flavor that becomes richer and more concentrated during roasting. Its soft flesh also makes an excellent base for a creamy filling.
Choose a squash that feels firm and heavy for its size, with smooth skin and no obvious soft spots. A medium squash should provide two sturdy halves that can hold the filling after the first bake.
2. Plain Greek Yogurt
Use 3/4 cup plain Greek yogurt.
Greek yogurt gives the filling a creamy consistency and a subtle tang that balances the sweetness of the squash. It also helps create a smooth texture without relying entirely on heavy cream or additional butter.
Choose plain, unsweetened yogurt rather than a flavored variety. Its thickness helps the filling maintain its consistency when returned to the oven.
3. Grated Parmesan Cheese
You’ll need 3/4 cup grated Parmesan cheese, divided.
Parmesan provides a savory, nutty flavor that complements the sweet squash and tangy yogurt. Half a cup goes into the filling, while the remaining quarter cup is sprinkled over the top before the second bake.
As the casserole finishes cooking, the cheese melts and develops a golden, flavorful surface.
4. Avocado Oil or Olive Oil
Use 1 tablespoon avocado oil or olive oil.
The oil coats the cut surfaces of the squash and helps them roast evenly. Either option works well, so choose whichever you have available.
5. Sea Salt and Freshly Ground Black Pepper
Season the squash and filling with sea salt and freshly ground black pepper to taste.
Salt enhances the natural flavors of the squash and cheese, while black pepper adds a gentle savory note. Since Parmesan is already salty, start with a modest amount and adjust the seasoning to your preference.
Kitchen Tools You’ll Need
You don’t need specialized equipment to make this recipe. Gather these everyday kitchen tools before you begin:
- A large baking dish
- A sharp knife
- A cutting board
- A spoon for removing the seeds and scooping the flesh
- A mixing bowl
- A fork for mashing
- Measuring cups and spoons
A sturdy knife is particularly helpful when cutting butternut squash lengthwise. Take your time when preparing the squash, and make sure it is positioned securely on the cutting board.
How to Make Twice Baked Butternut Squash
Follow these simple steps to create tender roasted squash filled with creamy Parmesan and Greek yogurt.
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C).
Starting with a fully heated oven helps the squash roast efficiently and develop a tender interior. While the oven heats, prepare the squash and gather the remaining ingredients.
Step 2: Prepare the Squash
Carefully cut the butternut squash in half lengthwise and remove the seeds.
Place both halves cut-side up in a large baking dish. Drizzle the exposed flesh with the avocado oil or olive oil, then season with sea salt and freshly ground black pepper.
Rub the oil and seasonings evenly over the cut surfaces so the squash is well coated.
Arrange the halves in the dish without overlapping them. Keeping them stable helps them roast evenly and makes them easier to handle later.
Step 3: Roast Until Fork-Tender
Place the baking dish in the preheated oven and roast the squash for 35–45 minutes.
The exact time depends on the size and thickness of the squash. Begin checking toward the earlier end of the cooking range by gently inserting a fork into the flesh.
The squash should be tender enough to scoop but not so soft that the outer shells collapse. These shells will hold the filling during the second bake, so maintaining their structure is important.
Step 4: Let the Squash Cool Slightly
Remove the baking dish from the oven and allow the squash to rest until it is safe to handle.
The flesh will be very hot immediately after roasting. Giving the squash a little time to cool makes scooping easier and reduces the risk of burns.
Keep the halves in the baking dish while you prepare to remove the flesh.
Step 5: Scoop Out the Flesh
Use a spoon to carefully scoop most of the softened squash into a mixing bowl.
Leave approximately 1/4 inch of flesh around the inside of each shell. This layer helps the shells remain sturdy enough to hold the filling.
Work gently and avoid piercing or tearing the skin. You want to create enough room for the filling while preserving the shape of each half.
If necessary, use the back of the spoon to smooth the remaining flesh slightly so the filling can be returned evenly.
Step 6: Make the Creamy Filling
Add the following ingredients to the scooped squash:
- 3/4 cup plain Greek yogurt
- 1/2 cup grated Parmesan cheese
- Sea salt, to taste
- Freshly ground black pepper, to taste
Use a fork to mash everything together until the mixture becomes creamy and evenly combined.
The filling should retain the characteristic flavor of the roasted squash while gaining richness from the yogurt and savory depth from the Parmesan.
Avoid overworking the mixture. A creamy consistency is ideal, but a little texture from the squash can make the finished dish more appealing.
Taste the filling and adjust the seasoning if needed.
Step 7: Refill the Squash Shells
Spoon the prepared mixture back into the two roasted squash shells.
Divide the filling as evenly as possible so each half has a generous layer. Use the back of the spoon to smooth the surface or leave it slightly textured for a more rustic appearance.
Arrange the stuffed halves securely in the baking dish so they remain upright during the second bake.
Step 8: Add the Remaining Parmesan
Sprinkle the remaining 1/4 cup grated Parmesan cheese over the stuffed squash.
Distribute the cheese evenly across both halves. This final layer adds flavor and helps create the attractive golden surface that makes twice-baked squash so appealing.
Step 9: Bake Again Until Golden
Return the stuffed squash to the oven and bake for 10 minutes.
Then switch to the broiler for 2–3 minutes, watching closely until the cheese becomes golden and bubbly.
Broilers can brown food very quickly, so stay nearby during this final step. Remove the squash once the topping reaches the desired color.
If the cheese begins browning too quickly, stop broiling rather than allowing the surface to burn.
Step 10: Serve While Hot
Remove the baking dish from the oven and serve the squash while the filling is hot and creamy.
For an attractive presentation, place each stuffed half on a serving platter or serve directly from the baking dish.
The combination of tender squash, tangy yogurt, and melted Parmesan makes this dish a satisfying addition to a cozy dinner or holiday spread.
Pro Tips for the Best Twice Baked Butternut Squash
A few practical tips can help you get the best results from this simple recipe.
Choose a Squash That Holds Its Shape
Select a medium squash with firm flesh and an intact exterior. The shells need to remain sturdy enough to support the filling after the first bake.
Check Tenderness Rather Than Relying Only on Time
The recipe recommends roasting for 35–45 minutes, but individual squash can cook at different rates. Test the flesh with a fork and remove the squash when it is tender enough to scoop while the shells remain intact.
Leave Enough Flesh Around the Shell
When scooping, keep approximately 1/4 inch of flesh around the inside. Removing too much can weaken the shells and make them difficult to refill.
Mash the Filling Until Creamy
Use a fork to combine the roasted squash, yogurt, and Parmesan. Mash thoroughly enough to create a cohesive filling, but don’t worry if a little texture remains.
Divide the Parmesan Carefully
Reserve half a cup of Parmesan for the filling and the remaining quarter cup for the topping. Adding the cheese in two stages ensures that the filling is flavorful and the surface develops a cheesy finish.
Watch the Broiler Closely
The final 2–3 minutes can make a big difference to the appearance of the dish. Keep a close eye on the cheese because it can move from golden to burnt quickly.
Serve Fresh for the Best Texture
This dish is especially enjoyable shortly after its second bake, when the filling is creamy and the Parmesan topping is warm and bubbly.
Easy Variations to Try
Although the original recipe is delicious as written, you can adjust the cheese or presentation to suit your preferences.
Twice Baked Butternut Squash with Pecorino Romano
Replace the Parmesan with Pecorino Romano for a sharper, saltier cheese flavor.
Because Pecorino Romano can be quite salty, taste the filling before adding extra salt.
Sharp Cheddar Butternut Squash
Use grated sharp cheddar instead of Parmesan for a more familiar, rich cheese flavor.
Cheddar changes the character of the recipe but pairs well with the naturally sweet squash. You can use it in the filling and on top, keeping the total cheese amount consistent with the original recipe.
A Garlic-Inspired Variation
If you enjoy garlic, you can experiment with adding a small amount of cooked garlic to the filling. It adds another savory layer that complements the cheese and squash.
This is an optional adaptation rather than part of the original ingredient list.
Fresh Herb Variation
Fresh thyme or parsley can add freshness to the finished dish. Sprinkle a small amount over the top just before serving.
Herbs work especially well if you are serving the squash alongside roasted chicken, grilled meat, or other savory dishes.
Make It a More Substantial Vegetarian Meal
Serve a stuffed squash half alongside a crisp green salad or roasted vegetables for a simple vegetarian meal.
For a vegetarian version, check that the Parmesan or alternative cheese uses suitable vegetarian ingredients, since traditional Parmesan may contain animal-derived rennet.
What to Serve with Twice Baked Butternut Squash
This recipe works as both a side dish and a vegetarian-friendly main course. Its creamy, savory filling pairs well with a wide range of meals.
Roast Chicken
Roast chicken is a natural companion to twice-baked butternut squash. The savory flavor of the chicken balances the sweetness of the squash, while the creamy filling makes the meal feel comforting and complete.
Grilled Steak
Serve the squash with grilled steak for a hearty dinner. The Parmesan topping and tender squash provide a satisfying contrast to the savory meat.
A Crisp Green Salad
A fresh salad is an excellent choice if you want to balance the richness of the cheese and yogurt.
Use crisp greens and a light dressing to add freshness without overpowering the squash.
Roasted Vegetables
Pair the squash with roasted carrots, broccoli, Brussels sprouts, or other seasonal vegetables for a colorful meal.
Holiday Dinner
This recipe makes a beautiful fall or winter side dish. Serve it alongside roasted poultry, other vegetable sides, and your favorite seasonal dishes.
Can You Make Twice Baked Butternut Squash Ahead of Time?
Yes. The original recipe recommends preparing the squash earlier in the day and finishing the baking just before serving.
Roast the squash, scoop out the flesh, prepare the filling, and return it to the shells. Cover and refrigerate the stuffed squash promptly rather than leaving it at room temperature for an extended period.
When you’re ready to serve, bake it until the filling is heated through, then finish under the broiler until the Parmesan becomes golden and bubbly.
Because refrigerated squash starts colder than freshly prepared squash, it may require more time than the original 10-minute second bake. Check the center before serving rather than relying solely on the original timing.
Preparing the dish ahead can make dinner parties and holiday cooking much more manageable.
Meal Prep and Leftover Storage
Twice Baked Butternut Squash can also be portioned for weekday meals.
Storing Leftovers
Allow leftovers to stop steaming, then refrigerate them promptly in a covered, airtight container.
For food safety, use refrigerated leftovers within 3–4 days. Avoid leaving the squash at room temperature for more than 2 hours.
Reheating
Place the leftover squash in an oven-safe dish and warm it in the oven until heated through. The exact reheating time will depend on the size of the portion and whether it is being reheated directly from the refrigerator.
You can also microwave individual portions in a microwave-safe container. The topping may not remain as crisp when reheated in the microwave, but the filling should still be creamy.
Freezing Considerations
The original recipe does not specify a freezing time or a tested freezing method. You can experiment with freezing portions in suitable containers, but the texture of the squash and Greek yogurt filling may change after thawing.
For the best texture, refrigeration and reheating within the recommended storage period are the most straightforward options.
Frequently Asked Questions
What Is Twice Baked Butternut Squash?
Twice baked butternut squash is made by roasting squash halves until tender, scooping out most of the flesh, mixing it with other ingredients, and returning the filling to the shells for a second bake.
In this recipe, the filling combines Greek yogurt, Parmesan, salt, and black pepper. A final layer of Parmesan creates a golden, bubbly topping.
Do I Need to Peel the Butternut Squash?
No. The squash is roasted in its skin, and the skin becomes the serving shell.
After the first bake, scoop out most of the flesh while leaving approximately 1/4 inch around the inside to help the shell maintain its structure.
Can I Use Regular Yogurt Instead of Greek Yogurt?
Plain Greek yogurt is the ingredient specified in the original recipe. Regular plain yogurt may be thinner, which can change the consistency of the filling.
If you decide to substitute it, choose an unsweetened option and consider its texture before mixing it into the squash.
Can I Use a Different Cheese?
Yes. The original recipe suggests Pecorino Romano or sharp cheddar as alternatives to Parmesan.
Each cheese has a different flavor and salt level, so taste the filling before adding additional seasoning.
How Do I Know When the Squash Is Ready?
After the first bake, the flesh should be fork-tender and easy to scoop while the shells remain sturdy.
After the second bake, the filling should be hot, and the Parmesan topping should be melted, golden, and bubbly.
Can I Prepare This Recipe in Advance?
Yes. Bake and stuff the squash earlier in the day, then refrigerate it until you’re ready to finish cooking.
Allow extra time for the center to heat through if the squash is cold from the refrigerator.
Is Twice Baked Butternut Squash Vegetarian?
The listed ingredients do not include meat, so the recipe can be suitable for a vegetarian diet. However, traditional Parmesan may use animal-derived rennet. Choose a cheese labeled suitable for vegetarians if that matters to your diet.
Can I Serve This as a Main Course?
Yes. The recipe is listed as both a main course and a side dish. Serve it with a crisp salad or additional vegetables for a simple vegetarian-friendly meal.
Why Should I Leave Some Flesh Around the Shell?
Leaving approximately 1/4 inch of squash around the inside helps the shells remain sturdy enough to hold the filling. Scooping too deeply may cause the shells to tear or collapse.
