Ingredients
This recipe makes 8 generous servings.
For the Caramelized Onions:
- 3 large yellow onions (about 2 lbs), thinly sliced
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon granulated sugar (optional, helps with browning)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 cup beef broth (or vegetable broth for vegetarian)
For the Mac and Cheese:
- 1 pound elbow macaroni or other small pasta shape
- 1/2 cup (1 stick) unsalted butter
- 1/2 cup all-purpose flour
- 4 cups whole milk, warmed
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/4 teaspoon nutmeg
- 1 teaspoon salt (or to taste)
- 1/2 teaspoon black pepper (or to taste)
- 4 cups shredded Gruyere cheese (about 12-16 oz), divided
- 2 cups shredded sharp white cheddar cheese (about 8 oz), divided
For the Topping:
- 1 cup panko breadcrumbs
- 2 tablespoons unsalted butter, melted
- 1/2 cup shredded Gruyere cheese
- 2 tablespoons fresh parsley, chopped (for garnish, optional)
Step-by-Step Instructions
-
Step 1: Caramelize the Onions
Heat 2 tablespoons of butter and 1 tablespoon of olive oil in a large, heavy-bottomed pot or Dutch oven over medium-low heat. Add the thinly sliced onions, sugar, salt, and pepper. Stir well to coat.
Cook the onions slowly for 35-45 minutes, stirring occasionally, until they are deeply golden brown and very soft. This process requires patience. Small tip: Do not rush this step. Low and slow heat is key for truly sweet, caramelized onions. If they start to stick, add a tablespoon of water.
Once caramelized, deglaze the pot by adding 1/2 cup of beef broth. Scrape up any browned bits from the bottom of the pot. Cook for another 2-3 minutes until the liquid has mostly evaporated. Set aside.
-
Step 2: Cook the Pasta
While the onions are caramelizing, bring a large pot of salted water to a rolling boil. Add the macaroni and cook according to package directions until al dente. This usually takes 7-9 minutes.
Drain the pasta well and set it aside. Do not rinse the pasta. Small tip: Cooking pasta slightly under al dente is best, as it will continue to cook in the oven.
-
Step 3: Make the Cheese Sauce
In the same large pot or a separate one, melt 1/2 cup of butter over medium heat. Add the all-purpose flour and whisk constantly for 1-2 minutes to create a roux. It should be light golden brown.
Gradually whisk in the warmed milk, a little at a time, to avoid lumps. Continue whisking until the sauce is smooth and thick, about 5-7 minutes. Small tip: Warming the milk beforehand helps prevent lumps and speeds up the thickening process.
Remove the pot from the heat. Stir in the Dijon mustard, garlic powder, nutmeg, salt, and pepper. Add 3 cups of Gruyere cheese and 1.5 cups of sharp white cheddar cheese. Stir until the cheeses are completely melted and the sauce is creamy and smooth.
-
Step 4: Combine and Bake
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Add the cooked macaroni to the cheese sauce. Gently fold in about two-thirds of the caramelized onions.
Pour the mac and cheese mixture into the prepared baking dish. Spread it evenly. Top with the remaining 1 cup of Gruyere cheese and 1/2 cup of sharp white cheddar cheese.
-
Step 5: Prepare the Topping and Bake
In a small bowl, combine the panko breadcrumbs with 2 tablespoons of melted butter. Mix well. Sprinkle the buttery panko over the cheese layer on the mac and cheese.
Bake for 20-25 minutes, or until the mac and cheese is bubbly and the topping is golden brown and crispy. Small tip: For an extra golden crust, you can place it under the broiler for the last 1-2 minutes, watching carefully to prevent burning.
Let the French Onion Mac and Cheese rest for 5-10 minutes before serving. Garnish with fresh chopped parsley if desired. Enjoy!
Tips & Variations
- Gluten-Free Option: Easily make this dish gluten-free by using your favorite gluten-free elbow macaroni and a gluten-free all-purpose flour blend for the roux. Ensure your broth is also gluten-free.
- Vegetarian Option: For a completely vegetarian dish, use vegetable broth instead of beef broth for deglazing the onions. The flavor will still be wonderfully rich.
- Add More Vegetables or Protein: Feel free to stir in some sautéed mushrooms, spinach, or even cooked shredded chicken for a more complete meal. Cooked bacon bits would also add a delicious smoky flavor.
- Spicy Version: If you love a little heat, add a pinch of red pepper flakes to the cheese sauce. A dash of hot sauce can also be mixed in for an extra kick.
- Different Cheeses: While Gruyere and sharp white cheddar are classic for French Onion Mac and Cheese, feel free to experiment! Swiss, Fontina, or even a good quality Provolone could be delicious additions or substitutions.
- Make Ahead: You can assemble the entire dish (without the panko topping) up to 24 hours in advance. Cover and refrigerate. Add the panko topping just before baking, and you might need to add an extra 10-15 minutes to the baking time if baking from cold.
