•Beef Broth: The rich broth mimics the flavors of French onion soup and adds depth to the pasta.

•Garlic & Thyme: Adds a boost of savory and aromatic flavor.

Recipe Steps for One Pot French Onion Pasta

Step 1: Caramelize the Onions

1.In a large pot, melt 2 tbsp butter over medium heat. Add 3 large thinly sliced onions and cook, stirring occasionally, until caramelized and golden brown (about 20-25 minutes).

Step 2: Add Garlic and Herbs

2.Stir in 3 minced garlic cloves and 1 tsp fresh thyme. Cook for 1-2 minutes until fragrant.

Step 3: Add Broth and Pasta

3.Add 4 cups of beef broth and bring to a boil. Stir in 12 oz of pasta and cook, uncovered, until the pasta is tender and has absorbed most of the liquid (about 10-12 minutes).

Step 4: Add Cheese

4.Stir in 1 cup of shredded Gruyère or Swiss cheese until melted. For extra richness, add ½ cup of heavy cream (optional). Taste and adjust seasoning with salt and pepper.

Step 5: Serve

5.Serve the pasta hot, topped with extra cheese and fresh thyme for garnish if desired.

Storage Options

•Refrigerator: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or on the stovetop with a splash of broth or water.

•Freezer: This pasta doesn’t freeze well due to the cheese and creamy texture, but it’s so good, it probably won’t last long enough to freeze!

Variations & Substitutions

•Vegetarian Option: Substitute beef broth with vegetable broth for a vegetarian-friendly version.

•Extra Veggies: Add sautéed mushrooms, spinach, or bell peppers for added flavor and nutrition.

•Cheese Options: Swap Gruyère with mozzarella or Parmesan if preferred.
