Ingredients
Scale
Macaroni
- 8 oz elbow macaroni
Onion Soup Base
- 4 large onions, thinly sliced
- 4 tablespoons butter
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 3 cups beef broth
- 1 teaspoon fresh thyme leaves (or 1/2 tsp dried thyme)
- Salt and pepper to taste
Cheese Blend
- 1 cup shredded Gruyère cheese
- 1 cup shredded sharp cheddar cheese
- 1/2 cup grated Parmesan cheese
Optional Topping
- Sliced baguette
- Extra Gruyère cheese for topping
Instructions
- Cook Macaroni: Cook macaroni according to package directions until al dente. Drain well and set aside to be added later into the cheese sauce.
- Caramelize Onions: In a large skillet over medium heat, melt the butter. Add the thinly sliced onions and cook slowly, stirring occasionally, for about 30-40 minutes until the onions are deeply caramelized and golden brown.
- Add Garlic: Stir in the minced garlic and cook for an additional minute to release its aroma without burning.
- Make Roux: Sprinkle the all-purpose flour over the caramelized onions and stir thoroughly to coat. Cook for 2 minutes to eliminate the raw flour taste, creating a roux base for the sauce.
- Add Broth and Thyme: Gradually whisk in the beef broth and add thyme leaves. Bring the mixture to a simmer and cook until the sauce thickens slightly, about 5 minutes.
- Melt Cheeses: Reduce heat to low and stir in the shredded Gruyère, sharp cheddar, and grated Parmesan until all cheeses are fully melted and the sauce becomes smooth and creamy.
- Combine with Macaroni: Add the cooked macaroni to the cheese sauce and mix well to ensure every piece is coated. Season with salt and pepper to taste.
- Optional Baking: For a baked finish, transfer the mac & cheese mixture to a baking dish. Top with sliced baguette pieces and extra Gruyère cheese. Broil until the topping is golden and bubbly, about 2-4 minutes. Watch carefully to avoid burning.
- Serve: Serve hot immediately, enjoying the rich flavors and creamy texture of this French Onion Soup inspired macaroni and cheese dish.
Notes
- Caramelizing onions slowly over medium heat is key to developing the deep, sweet flavor reminiscent of French onion soup.
- Use freshly shredded cheese for the best melting texture and flavor.
- Baking with baguette topping adds a crunchy contrast but can be skipped for a simpler stovetop version.
- For a vegetarian version, substitute beef broth with vegetable broth.
- This dish pairs wonderfully with a simple green salad for a complete meal.
