Instructions

Follow these steps to create your French Onion Soup Mac & Cheese:

Caramelize the Onions

In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook slowly, stirring frequently, until they are caramelized and golden brown, about 20 minutes.

Prepare the Broth

Add the beef broth and thyme to the caramelized onions. Season with salt and pepper to taste. Allow the mixture to simmer for 10 minutes.

Cook the Pasta

Meanwhile, cook the elbow macaroni in a large pot of salted boiling water according to package instructions. Drain and set aside.

Combine Pasta and Cheese

In a large mixing bowl, combine the cooked pasta with the onion and broth mixture. Stir in the Gruyère and mozzarella cheeses until well mixed.

Bake the Dish

Transfer the mixture to a greased baking dish. Top with Parmesan cheese and breadcrumbs if desired. Bake at 350°F (175°C) for 15-20 minutes or until the cheese is bubbly and golden brown.

Let the dish cool slightly before serving. Enjoy your delicious French Onion Soup Mac & Cheese!

Tips for Perfect Caramelized Onions

Caramelizing onions can seem intimidating, but it's a simple process that produces incredible depth of flavor. To achieve the perfect caramelization, allow the onions to cook slowly over medium heat. Resist the urge to rush; patience is key. Stir occasionally to ensure they cook evenly and do not burn, resulting in rich, golden brown, sweet-tasting onions.

For an even more complex flavor profile, you might consider adding a splash of balsamic vinegar or a sprinkle of sugar to the onions during the cooking process. This will enhance their sweetness and lend a beautiful color.

Serving Suggestions

This French Onion Soup Mac & Cheese is hearty enough to stand alone, but it pairs wonderfully with a crisp side salad or some garlic bread for a complete meal. A simple green salad with a light vinaigrette can provide a refreshing balance to the richness of the mac and cheese.

For an added touch, consider garnishing each serving with a sprinkle of fresh herbs like parsley or thyme. Not only do they add a burst of color, but they also contribute a fresh flavor that rounds out this comforting dish perfectly.

Storing and Reheating Your Dish

To store leftovers, make sure the dish has completely cooled before transferring it to an airtight container. Refrigerate for up to three days, or freeze for up to two months. If freezing, consider leaving off the breadcrumb topping until you are ready to bake it again to maintain the ideal texture.

When reheating, you can add a splash of milk to restore creaminess before warming it up. Cover the dish with foil to keep the heat in, and remove the foil for the last few minutes to allow the cheese to brown beautifully. Enjoy your delicious leftovers just like the first time!
