The Recipe: French Onion Mac and Cheese
French Onion Mac and Cheese
David Leite
Ingredients
- 7 tablespoons (3 1/2 ounces) unsalted butter, divided
- 3 large (1 1/4 lbs) onions, thinly sliced
- Salt
- 1 cup dry white wine
- Leaves from a small bunch of thyme
- 1 pound macaroni
- 1/4 cup all-purpose flour
- 3 1/3 cups whole milk
- 7 ounces extra-mature Cheddar cheese, grated
- 7 ounces Gruyère cheese*, grated
- 1 heaping teaspoon Dijon mustard
- 3 1/2 ounces breadcrumbs
- Freshly ground black pepper
Instructions
Caramelize the onions
-
In a large skillet over medium heat, melt 2 1/2 tablespoons of the unsalted butter. Add the thinly sliced onions along with a generous pinch of salt. Sauté, stirring occasionally and adjusting the heat downwards if the onions start to brown too quickly. Continue cooking for about 30 minutes, or until the onions have become deeply softened and beautifully caramelized, developing a rich, sweet flavor.
-
Once the onions are perfectly caramelized, pour in the dry white wine. Add most of the fresh thyme leaves, ensuring you reserve a small handful for garnishing the finished dish. Allow the mixture to simmer gently until the wine has reduced by approximately half, which should take about 2 to 4 minutes. These caramelized onions can be prepared ahead of time and stored in the refrigerator until you’re ready to assemble the mac and cheese.
-
In a large saucepan, bring a generous amount of salted water to a rolling boil. Add the macaroni and cook it for 2 minutes less than the recommended cooking time on the package instructions. This ensures the pasta remains al dente and can absorb the delicious cheese sauce without becoming mushy. Drain the macaroni thoroughly in a colander.
Make the cheese sauce
-
In a separate large, ovenproof skillet (or a Dutch oven), melt the remaining 4 1/2 tablespoons of butter over medium heat. Once melted, add the all-purpose flour and whisk continuously for 1-2 minutes to create a smooth roux. Gradually and slowly pour the cold whole milk into the roux, whisking constantly to prevent lumps. Continue whisking and simmering the sauce until it thickens to your desired consistency, which typically takes about 5 minutes.
-
Stir in the grated extra-mature Cheddar cheese and half of the grated Gruyère cheese into the thickened sauce. Continue stirring until both cheeses have completely melted, forming a rich, smooth, and creamy cheese sauce. Remove the skillet from the heat, then stir in the heaping teaspoon of Dijon mustard. Season the sauce generously with salt and freshly ground black pepper to taste.
-
Preheat your broiler to high heat. This will create a wonderfully golden and crispy topping for your mac and cheese.
-
Add the cooked macaroni and most of the caramelized onions to the cheese sauce in the ovenproof skillet, reserving about a tablespoon of the caramelized onions for the topping. Mix all ingredients thoroughly until the macaroni and onions are evenly coated in the rich cheese sauce. Then, evenly spread the reserved caramelized onions, the remaining Gruyère cheese, and the breadcrumbs over the top of the mac and cheese. Scatter the handful of reserved thyme leaves over the topping for added aroma and visual appeal.
-
Carefully place the skillet under the preheated broiler. Broil for 2 to 4 minutes, or until the topping is beautifully golden brown and bubbly. Keep a close eye on it, as broilers can brown quickly. Serve this magnificent French Onion Mac and Cheese immediately for the best experience.
Notes
*What can I substitute for Gruyère?
Choosing a substitute for Gruyère largely depends on why you’re looking for an alternative. If the distinct taste of Gruyère isn’t to your liking but you still desire a second melting cheese in your dish, consider a milder option like Emmental. Emmental offers a similar delightful meltiness and texture, but with a less assertive flavor profile.
For those simply looking to avoid the expense often associated with gourmet cheeses, MOB Kitchen suggests a practical solution: use extra sharp Cheddar for the entire cheese quantity, totaling 14 ounces (400 grams). While this alteration might slightly diminish the characteristic “French oniony” nuance that Gruyère brings, the resulting mac and cheese will still be exceptionally incredible and satisfying, delivering robust cheesy goodness.

Beyond the Recipe: Expert Tips and Serving Suggestions
Mastering this French Onion Mac and Cheese goes beyond just following the steps; it’s about embracing the nuances that elevate a good dish to a great one. The magic truly begins with the caramelized onions. Don’t rush this step—the 30 minutes of slow cooking over medium-low heat are crucial for developing their deep, sweet, and complex flavor. Patience here will be richly rewarded. When making the cheese sauce, always add cold milk to your roux gradually while whisking constantly. This technique is key to achieving a silky-smooth sauce free of lumps, ensuring every bite of your mac and cheese is wonderfully creamy.
For serving, this rich and savory dish pairs beautifully with simple, fresh accompaniments. A crisp green salad with a light vinaigrette provides a refreshing contrast to the richness of the mac and cheese. If you enjoy wine, a glass of Pinot Grigio, as suggested by one of our testers, complements the flavors perfectly, especially since it’s the same wine used in the recipe. This dish is hearty enough to stand alone as a main course, making it an ideal candidate for your “Hump Day” dinner, a cozy weekend meal, or even a standout vegetarian option for holiday gatherings like Thanksgiving.
Feeling adventurous? You can easily customize this recipe. Consider adding sautéed mushrooms for an earthy depth or a sprinkle of red pepper flakes for a subtle kick, as Amy Kaufman suggests. For an even more decadent experience, a few strips of crispy bacon could be crumbled into the mac and cheese before baking. If you have leftovers, this dish reheats remarkably well. For best results, cover it with foil when reheating in the oven to prevent the topping from burning and to retain moisture, uncovering for the last few minutes if you want to crisp up the topping again.

Sasha Pravdic
Two of the greatest comfort foods in the world joined together–what could be better? This was a creamy, tasty, indulgent treat! I loved the flavor of the caramelized onions mixed in with the mac & cheese. I used an ordinary store brand sharp Cheddar cheese along with Gruyère and it turned out fantastic.
The only thing that I’d do differently next time is I would bake it until the bread crumbs were brown and the pasta was bubbly rather than trying to broil. My topmost layer of bread crumbs started to burn pretty quickly before the pasta had a chance to get bubbly. I served this with fresh sliced garden tomatoes and a glass of Pinot Grigio (which was the same wine I used in the recipe).
Adrienne Lee
Our family loves French onion soup and this French onion mac and cheese seemed like a fantastic crossover dish. The flavor was really good and it was good enough that other family members got up to serve themselves more. Note that it is an involved dish and might go faster if you do the onion the day before but it definitely seems like a good weekend bake or a great vegetarian option for Thanksgiving.
Amy Kaufman
As promised, this marriage of mac and cheese and French onion soup is as sumptuous as it sounds. It’s rich and cheesy like your classic mac and cheese baked pasta but with some sweeter notes from caramelized onions infused with white wine. Extra bonus is the Gruyère breadcrumb lid.
So good and so easy to prepare, giving much comfort and coziness. I’d encourage a generous seasoning of salt through all the stages. I also suggest some red pepper flakes for some subtle heat. Watch the broiling stage carefully. My dish crisped up quickly! Enjoy.
This French Onion Mac and Cheese isn’t just a recipe; it’s an invitation to savor the magic that happens when two beloved comfort foods unite. With its rich flavors, creamy texture, and irresistible topping, it promises to be a memorable dish for any occasion. Whether it’s a cozy weeknight or a special gathering, this fusion masterpiece is sure to become a cherished favorite in your culinary repertoire. Enjoy the delicious journey!
