# How to Make It:
01 -
Melt butter in a large skillet over low heat. Add thinly sliced yellow onions and cook slowly, stirring occasionally, for 30 to 40 minutes until golden brown and deeply caramelized.
02 -
Sprinkle the caramelized onions with flour and mix thoroughly. Gradually whisk in beef broth and half-and-half or heavy cream, stirring constantly until smooth and thickened. Incorporate minced garlic and dried thyme, then add Gruyère and sharp white cheddar cheese. Stir until the cheese is fully melted and the sauce is creamy. Season generously with salt and black pepper.

Cook elbow macaroni according to package directions until al dente. Drain well. Fold the pasta into the cheese and onion mixture, ensuring even coating with the sauce.
04 -
Transfer the macaroni and cheese to an oven-safe dish. Top with additional grated cheese and, if desired, toasted baguette slices. Broil under medium heat until the cheese topping is bubbling and golden brown, closely monitoring to prevent burning.
# Extra Tips:
01 -
For a vegetarian version, substitute beef broth with vegetable broth and ensure cheese is vegetarian-friendly.
02 -
Serve immediately for the creamiest texture and optimal flavor.
