How to Make French Onion Soup Mac and Cheese
Ingredients
- 3 large yellow onions, thinly sliced
- 3 tbsp butter
- 2 cloves garlic, minced
- 1 tsp dried thyme
- Salt and freshly ground black pepper, to taste
- 3 tbsp all-purpose flour
- 4 cups beef broth (or vegetable broth for vegetarian option)
- 1 cup half-and-half or heavy cream
- 1 ½ cups grated Gruyère cheese
- 1 cup sharp white cheddar cheese, grated
- 12 oz elbow macaroni
- Optional: French bread or baguette slices for toasting
- Extra grated cheese for topping (about ½ cup)
Step-by-Step Instructions
-
Caramelize the Onions: In a large pan, melt the butter over low heat. Add the thinly sliced onions and cook slowly, stirring occasionally, for about 30-40 minutes. You’ll want them to turn golden brown while developing a rich sweetness and deep flavor. Patience here is key – don’t rush the process!
-
Create the Cheese Sauce: Once the onions are caramelized, sprinkle the flour over them and stir to coat. Gradually whisk in the broth and half-and-half until you achieve a smooth sauce. Add the minced garlic and dried thyme next. Now comes the fun part: melt in the Gruyère and sharp white cheddar cheese, stirring until everything is creamy and combined. Don’t forget to season with salt and pepper to taste!
-
Cook the Pasta: Boil your elbow macaroni according to package instructions, ensuring it’s al dente. Drain well, but reserve a little pasta water so you can adjust the sauce later if needed.
-
Combine and Bake: Mix the cooked macaroni into the cheese sauce until every piece is heavenly coated. Transfer this mix to an oven-safe dish, top it off with extra grated cheese and toasted baguette slices for that classic French onion soup touch. Broil for a few minutes until the top is bubbly and golden brown, making sure to keep an eye on it to prevent burning.
Pro Tips
-
Caramelize Slowly: Take your time with the onions. If you rush this step, you may end up with a burnt flavor rather than the sweet, rich taste that defines French onion soup.
-
Choose Quality Cheese: A good Gruyère is essential for that nutty flavor. If you can find some high-quality cheese from a local cheesemonger, it’s definitely worth the purchase.
-
Pasta Type Matters: While elbow macaroni is traditional, feel free to swap in other pasta shapes like cavatappi or shells for a fun twist.
-
Adjust Consistency: If your cheese sauce is too thick after mixing in the pasta, gradually add some reserved pasta water to achieve your desired creaminess.
-
Experiment with Toppings: Consider adding herbs or even crispy bacon as a topping for an extra layer of flavor and texture.

How to Store French Onion Soup Mac and Cheese

To reheat, let it thaw overnight in the fridge if frozen, or heat in the microwave with a splash of milk to prevent it from drying out. You can also reheat it in the oven; cover it with foil to keep moisture in, then pop it at 350°F until warmed through.
Tips to Make French Onion Soup Mac and Cheese Even Better
-
Think Seasoning: Taste your cheese sauce before mixing in the pasta. Depending on the saltiness of your cheeses and broth, you may want to adjust the seasonings.
-
Add Fresh Herbs: Fresh thyme or parsley sprinkled on top adds a pop of flavor and color.
-
Experiment with Pasta: Different types of pasta can change the dish significantly. Try whole grain for added nutrition or gluten-free options if you’re catering to dietary restrictions.
Variation Ideas
-
Vegan Version: Substitute all dairy products with alternatives—use vegan cheese and almond or soy milk in place of half-and-half.
-
Add Spice: For a little kick, consider adding crushed red pepper flakes or a dash of hot sauce to the cheese sauce.
-
Bacon Bits: If you’re a meat lover, crispy bacon or pancetta mixed in with the pasta elevates the flavor profile even more.
