Ingredients

Ingredients for French Onion Soup Mac & Cheese

8 oz elbow macaroni
2 large onions, thinly sliced
4 cups beef broth
2 tbsp unsalted butter
1 tbsp olive oil
2 cups shredded Gruyère cheese
1 cup shredded cheddar cheese
1/2 cup bread crumbs
Salt and pepper to taste
Fresh thyme for garnish

Gather all your ingredients before starting to ensure a smooth cooking process.

Instructions

Cook the Pasta

In a large pot, boil salted water and cook the macaroni according to package instructions. Drain and set aside.

Sauté the Onions

In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook until they are caramelized, about 15-20 minutes.

Add Broth and Cheese

Stir in the beef broth and bring to a simmer. Reduce heat and mix in the Gruyère and cheddar cheese until melted and smooth.

Combine and Bake

Add the cooked macaroni to the cheese sauce, mixing well. Transfer to a baking dish, top with bread crumbs, and bake at 350°F (175°C) for 15 minutes.

Garnish and Serve

Garnish with fresh thyme before serving for an extra touch of flavor.

Let the dish cool slightly before serving to allow the flavors to meld.

Storage and Reheating

If you find yourself with leftovers, you can store this French Onion Soup Mac & Cheese in an airtight container in the refrigerator for up to three days. When it’s time to enjoy it again, simply reheat portions in the microwave or in the oven. If reheating in the oven, cover it with foil to prevent drying out, and add a sprinkle of cheese on top for an extra gooey finish.

For longer storage, consider freezing the mac and cheese before baking. Just make sure it’s fully assembled but unbaked. Wrap it tightly in plastic wrap and then in aluminum foil to minimize freezer burn. When ready to enjoy, bake from frozen, allowing a little extra time. This makes it a convenient meal option for busy days ahead!

Pairing Suggestions

To complement the rich flavors of French Onion Soup Mac & Cheese, consider serving it with a bright, crisp green salad dressed lightly with vinaigrette. The acidity will balance the richness of the cheese and onions, creating a harmonious meal. Additionally, roasted vegetables can add texture and nutrient balance, making your dinner plate more vibrant.

When it comes to beverage pairings, a light red wine, such as Pinot Noir, or a refreshing sparkling water with lemon can enhance the dining experience. These options create a lovely contrast to the creamy dish and help to cleanse the palate. Celebrate your culinary creation with thoughtful side dishes and drinks for a well-rounded and satisfying meal.
