French Onion Soup Mac and Cheese: Comfort Food Delight!

Ingredient Notes

When making French Onion Soup Mac Cheese, the key ingredients work together to create that rich, comforting flavor profile. Here’s what you’ll need:

  • Elbow Macaroni: I love using elbow macaroni for its ability to hold onto the cheese sauce. However, you can substitute with cavatappi or shells for a different texture.
  • Onions: Sweet onions, like Vidalia or yellow onions, are best for achieving that caramelized flavor. If you’re in a pinch, white onions can work too, but they’ll be a bit sharper in taste.
  • Beef Broth: This is essential for that French onion soup essence. If you prefer a vegetarian option, vegetable broth will still give a lovely depth, although it will be milder.
  • Gruyère Cheese: The classic choice for French onion soup, Gruyère melts beautifully and has a nutty flavor. If you can’t find it, Swiss cheese or a blend of mozzarella and Parmesan can be a good substitute.
  • Butter: This is used for sautéing the onions. If you want a lighter option, you can replace it with olive oil.
  • Heavy Cream: This adds creaminess to the mac and cheese. For a lighter version, you can use half-and-half or whole milk.
  • Thyme: Fresh thyme gives a lovely herbal note. Dried thyme can work in a pinch, but use it sparingly (about a third of the amount).

Step-by-Step Instructions

Now, let’s dive into the steps for making this delicious French Onion Soup Mac Cheese!

  1. Prepare the Pasta: Cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
  2. Caramelize the Onions: In a large pot, melt 2 tablespoons of butter over medium heat. Add thinly sliced onions and a pinch of salt. Cook, stirring frequently, for about 20-25 minutes, until the onions are golden brown and caramelized. If they start to stick, add a splash of beef broth to deglaze the pot.
  3. Add Broth and Thyme: Once the onions are caramelized, pour in 4 cups of beef broth, add 1 teaspoon of thyme, and bring to a simmer. Let it cook for another 10 minutes to let the flavors meld.
  4. Make the Cheese Sauce: In a separate saucepan, melt 3 tablespoons of butter over medium heat. Stir in 3 tablespoons of flour to create a roux, cooking for about 2 minutes. Gradually whisk in 2 cups of heavy cream and let it thicken for a few minutes. Stir in 2 cups of grated Gruyère cheese until melted and smooth.
  5. Combine Everything: Mix the cooked macaroni into the cheese sauce, then stir in the onion and broth mixture until everything is well combined. Season with salt and pepper to taste.
  6. Bake (Optional): For a crispy top, transfer the mac and cheese to a baking dish, sprinkle with more Gruyère and some breadcrumbs, and broil for 3-5 minutes until golden brown.
  7. Serve Hot: Serve your French Onion Soup Mac Cheese hot, garnished with a few sprigs of fresh thyme if desired.

Tips & Suggestions

Here are some tips to elevate your French Onion Soup Mac Cheese:

  • Cheese Variations: Feel free to experiment with different cheeses. A sharp cheddar or a bit of blue cheese can add unique flavors.
  • Texture Boost: For added texture, consider folding in some sautéed mushrooms or crispy bacon bits (using beef bacon) into the mac and cheese.
  • Making Ahead: You can prepare the dish ahead of time. Assemble everything and refrigerate it. When you’re ready to eat, bake it straight from the fridge, adding a few extra minutes to the cooking time.
  • Garnish: A sprinkle of chopped parsley or chives adds a fresh touch and a pop of color to your dish.

Storage

If you have leftovers (which is rare because it’s so delicious), here’s how to store them:

  • Refrigeration: Store your French Onion Soup Mac Cheese in an airtight container in the refrigerator for up to 3 days.
  • Reheating: Reheat in the oven at 350°F until warmed through, or microwave in short intervals, stirring in between.
  • Freezing: You can freeze the mac and cheese before baking. Just thaw it in the fridge overnight before baking, and then follow the baking instructions.

Enjoy your comforting bowl of French Onion Soup Mac Cheese, a perfect blend of flavors and textures that brings the essence of cozy French cuisine to your table!
