How to Make French onion soup mac & cheese

Step 1: Caramelize the Onions

Start by slowly cooking those thinly sliced yellow onions in butter over low heat. This step is crucial! Take your time—let them cook for about 30-40 minutes until they turn golden brown and develop a rich, sweet flavor. Stir occasionally, and watch as they transform into caramelized beauties that will infuse your dish with incredible depth.

Step 2: Make the Cheese Sauce

Once your onions are perfectly caramelized, sprinkle flour over them and stir well to coat. Gradually whisk in your beef or vegetable broth along with half-and-half until it’s smooth and thickened. Adding minced garlic and dried thyme at this stage elevates the aroma. Then, melt in that Gruyère and sharp white cheddar until everything is creamy and combined. Don’t forget to season with salt and pepper to taste.

Step 3: Cook the Pasta

Boil your elbow macaroni according to package instructions until al dente. This means they should still have a slight bite—perfect for holding onto all that luscious sauce! Drain well, but remember to reserve a small amount of pasta water just in case you need it later.

Step 4: Combine Pasta with Sauce

Now comes the fun part! Mix those cooked macaroni into your cheesy sauce, ensuring every piece is evenly coated with that velvety goodness. This step ensures every bite bursts with flavor.

Step 5: Bake to Perfection

Transfer your mac & cheese mixture into an oven-safe dish. Top with extra grated cheese (because why not?) and add toasted baguette slices if you’re feeling fancy. Broil briefly until the top is bubbly and golden brown—just like the classic French onion soup crouton finish you adore. Keep an eye on it so it doesn’t burn!

And there you have it! A comforting bowl of French onion soup mac & cheese that’s sure to warm your heart and satisfy your cravings. Enjoy!

Pro Tips for Making French onion soup mac & cheese

Creating the perfect French onion soup mac & cheese is all about attention to detail and a few insider tricks. Here are some pro tips to ensure your dish turns out creamy, cheesy, and utterly delightful!

Caramelize Slowly: Taking your time with the onions allows them to develop a deep, sweet flavor that forms the backbone of this dish. Resist the urge to rush this step; patience pays off in taste!
Choose Quality Cheese: Using high-quality Gruyère and sharp white cheddar can elevate your mac & cheese from good to extraordinary. These cheeses melt beautifully and provide a rich, complex flavor profile.
Reserve Pasta Water: Keeping a bit of pasta water can be a lifesaver if your cheese sauce becomes too thick. Just add a splash to loosen it up while still keeping it creamy.
Broil for Texture: Broiling your mac & cheese at the end gives it that desirable crispy top. Keep an eye on it during this step to achieve the perfect golden-brown crust without burning.
Mix in Extras: For added depth, consider mixing in some sautéed mushrooms or spinach before baking. These ingredients not only boost nutrition but also enhance the flavor profile of your dish.
