Ingredient Notes

For my French Onion Soup Mac Cheese, the ingredients play a crucial role in capturing that rich, savory flavor profile. Here’s what you’ll need:

  • Pasta: I recommend using elbow macaroni or cavatappi for the perfect cheesy bite. You can substitute with gluten-free pasta if needed.
  • Onions: Sweet onions like Vidalia or yellow onions work best for that classic French onion flavor. If you want a slight twist, try using shallots for a milder taste.
  • Butter: Unsalted butter is ideal, but you can use olive oil for a lighter option.
  • Beef Broth: A rich beef broth is essential for depth. If you prefer a vegetarian option, vegetable broth will do just fine.
  • Cheese: Gruyère is the star cheese here, bringing that gooey texture and nutty flavor. You can combine it with mozzarella or cheddar for added creaminess. For a non-dairy alternative, look for vegan cheese options that melt well.
  • Thyme: Fresh thyme adds a lovely herbal note. Dried thyme can be used in a pinch.
  • Garlic: Fresh garlic enhances the overall taste, but garlic powder can be a fast substitute.

Step-by-Step Instructions

Now, let’s dive into making this comforting dish. Follow these simple steps to create your own French Onion Soup Mac Cheese:

  1. Caramelize the Onions: In a large pot, melt 3 tablespoons of butter over medium heat. Add 3 large sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for about 30-40 minutes until they are golden brown and caramelized.
  2. Add Garlic and Thyme: Once the onions are nicely caramelized, add 2 minced garlic cloves and 1 teaspoon of fresh thyme (or ½ teaspoon dried). Cook for an additional 2 minutes until fragrant.
  3. Deglaze the Pot: Pour in 1 cup of beef broth and scrape up any delicious bits stuck to the bottom of the pot. Let it simmer for about 5 minutes.
  4. Cook the Pasta: In a separate pot, cook 8 ounces of pasta according to the package instructions until al dente. Drain and set aside.
  5. Make the Cheese Sauce: In the same pot used for the onions, melt 4 tablespoons of butter over medium heat. Stir in ¼ cup of all-purpose flour and cook for 1-2 minutes. Gradually whisk in 2 cups of beef broth and bring to a gentle boil, stirring until thickened. Reduce heat to low, then mix in 2 cups of grated Gruyère and 1 cup of shredded mozzarella until melted and creamy.
  6. Combine Everything: Stir the cooked pasta into the cheese sauce and mix until fully coated. Add the caramelized onion mixture and stir until well incorporated.
  7. Transfer to Baking Dish: Pour the mac and cheese into a greased baking dish. Top with additional cheese if desired.
  8. Bake: Preheat your oven to 350°F (175°C) and bake for 20-25 minutes until bubbly and golden on top.

Tips & Suggestions

Here are some helpful tips to ensure your French Onion Soup Mac Cheese turns out perfect:

  • Onion Caramelization: Take your time with caramelizing the onions. The longer they cook, the sweeter and more flavorful they become. Don’t rush this step!
  • Cheese Variations: Feel free to experiment with cheese blends. A mix of Gruyère and sharp cheddar can add an extra kick.
  • Herb Additions: Fresh herbs like parsley or chives sprinkled on top before serving can brighten the dish.
  • Crunchy Topping: For a crunchy topping, mix breadcrumbs with melted butter and sprinkle on top before baking.
  • Make-ahead Option: You can prepare the mac cheese ahead of time, cover it, and refrigerate. Just bake it when you’re ready to enjoy!

Storage

Storing your French Onion Soup Mac Cheese properly will keep it delicious for days:

  • Refrigeration: Allow any leftovers to cool completely. Store them in an airtight container in the refrigerator for up to 3-4 days.
  • Freezing: You can freeze the macaroni and cheese before baking. Wrap it tightly in plastic wrap and foil, and it should last for up to 2 months. When ready to eat, thaw in the refrigerator overnight and bake as directed.
  • Reheating: Reheat in the oven at 350°F (175°C) until warmed through, or microwave individual portions for a quick meal.

Enjoy the comforting flavors of French Onion Soup Mac Cheese, a delightful twist on a classic dish!
