Ingredients

  • yellow onions
    3 large
  • butter
    3 tbsp
  • garlic
    2 clove
  • thyme
    1 tsp
  • Salt and freshly ground black pepper
  • all-purpose flour
    3 tbsp
  • beef broth
    4 c
  • half-and-half or heavy cream
    1 c
  • Gruyère cheese
    1 ½ c
  • sharp white cheddar cheese
    1 c
  • elbow macaroni
    12 oz
  • Optional: French bread or baguette slices for toasting
  • Extra grated cheese for topping

Directions

  1. 1

    Slowly cook thinly sliced yellow onions in butter over low heat for 30-40 minutes, stirring occasionally, until they turn golden brown and develop a rich, sweet flavor.

  2. 2

    Sprinkle flour over the caramelized onions and stir well to coat. Gradually whisk in the beef or vegetable broth and half-and-half or heavy cream until smooth and thickened. Add minced garlic and dried thyme, then melt in Gruyère and sharp white cheddar cheeses until creamy and combined. Season with salt and pepper to taste.

  3. 3

    Boil elbow macaroni according to package instructions until al dente. Drain well, reserving a small amount of pasta water in case you need to loosen the sauce later.

  4. 4

    Mix the cooked macaroni into the cheese sauce, ensuring every piece is evenly coated with the luscious, velvety sauce.

  5. 5

    Transfer the mac & cheese to an oven-safe dish. Top with extra grated cheese and toasted baguette slices if desired. Broil briefly until the top is bubbly and golden brown, mimicking the classic French onion soup crouton finish. Watch carefully to avoid burning.

Tips for Perfect French Onion Soup Mac & Cheese

  • Patience with Onions: The key to authentic flavor is properly caramelized onion mac and cheese. Don't rush this step; allow the onions to slowly turn golden brown and sweet. This builds the foundational flavor.
  • Broth Choice Matters: For a truly rich taste, use high-quality beef broth. For a delicious vegetarian option, a good vegetable broth works wonderfully.
  • Cheese Blend: The combination of nutty Gruyère and sharp white cheddar is critical for that iconic French onion soup profile, but feel free to experiment with other good melting cheeses like Fontina or even a touch of Parmesan for an extra salty kick.

Serve this decadent cheesy pasta with a simple green salad to balance the richness, or alongside your favorite roasted meats. And don't forget a sprinkle of extra grated cheese on top for that irresistible bubbly, golden crust!
