  • ¼ cup of salted butter, split
  • 1 onion, quartered and thinly sliced
  • 7 ounces of shredded gruyere cheese
  • 2 cloves of garlic, minced
  • 2 tablespoons of all-purpose flour
  • ½ cup of heavy cream
  • 1 ½ cups of whole milk
  • Salt and pepper to taste


1. Prepare the Ingredients:

  1. Boil the macaroni according to the package instructions until al dente. Drain and set aside.
  2. Cook the bacon until crispy, then chop or crumble it into small pieces. Set aside.
  3. Quarter the onion and thinly slice it. Mince the garlic cloves. Shred the gruyere cheese if not already shredded.

2. Caramelize the Onions:

  1. In a large skillet, melt 2 tablespoons of butter over medium heat.
  2. Add the sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, about 20-25 minutes.
  3. Add the minced garlic to the skillet and cook for an additional 1-2 minutes until fragrant. Remove from heat and set aside.

3. Make the Cheese Sauce:

  1. In a separate saucepan, melt the remaining 2 tablespoons of butter over medium heat.
  2. Whisk in the flour to create a roux, cooking for 1-2 minutes until golden brown.
  3. Slowly pour in the heavy cream and whole milk, whisking constantly to prevent lumps from forming.
  4. Cook the sauce until it thickens and coats the back of a spoon, about 5-7 minutes.
  5. Stir in the shredded gruyere cheese until melted and smooth. Season with salt and pepper to taste.

4. Combine and Bake:

  1. Preheat the oven to 350°F (175°C).
  2. In a large mixing bowl, combine the cooked macaroni, caramelized onions, and bacon pieces.
  3. Pour the cheese sauce over the macaroni mixture and stir until everything is evenly coated.
  4. Transfer the mac and cheese mixture to a greased baking dish.
  5. Bake in the preheated oven for 20-25 minutes, or until bubbly and golden brown on top.

5. Serve and Enjoy:

  1. Remove the French Onion Mac & Cheese from the oven and let it cool slightly before serving.
  2. Garnish with additional shredded gruyere cheese and chopped fresh parsley, if desired.
  3. Serve hot and enjoy the irresistible combination of flavors and textures!

  • Vegetarian Option: Omit the bacon for a vegetarian-friendly version of this dish. You can also add caramelized mushrooms or roasted vegetables for added depth of flavor.
  • Gluten-Free Option: Use gluten-free macaroni and substitute gluten-free flour for the all-purpose flour to make this recipe gluten-free.
  • Extra Cheesy: For cheese lovers, add extra shredded gruyere or mix in some shredded mozzarella or fontina cheese for an even cheesier mac & cheese.
  • Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce for a spicy kick.
