Creating One Pot French Onion Pasta

Step 1: Caramelize Onions

Melt butter and olive oil in a large pot over medium heat.

Add sliced onions and cook slowly, stirring occasionally, until they turn a deep golden brown and become sweet and soft.

This process takes about 20-25 minutes, so be patient and let the onions develop rich, deep flavor.

Step 2: Bloom Aromatics

Add minced garlic to the caramelized onions and sauté for 30-60 seconds until fragrant.

Sprinkle all-purpose flour over the mixture and stir continuously for another minute to cook out the raw flour taste and create a thickening base for the sauce.

Step 3: Create Liquid Base

Gradually pour chicken or vegetable broth into the pot, whisking constantly to prevent lumps.

Increase heat and bring the liquid to a gentle boil, creating a flavorful foundation for the pasta.

Step 4: Cook Pasta

• Penne
• Fusilli
• Rigatoni

Stir occasionally to prevent sticking and ensure even cooking.

Allow pasta to simmer until it reaches al dente texture, absorbing the delicious onion-infused broth.

Step 5: Finish with Creamy Cheese

• Heavy cream
• Shredded Gruyère cheese

Continue stirring until cheese melts completely, creating a luxurious, silky sauce that coats every pasta strand.

Step 6: Season and Serve

• Kosher salt
• Freshly ground black pepper

Garnish with fresh thyme or chopped parsley.

Serve immediately in warm bowls, allowing the rich, comforting flavors to shine.

Tips for Flavorful French Onion Pasta

• Take time to develop rich, deep flavor by cooking onions over medium-low heat, stirring occasionally to prevent burning.
• Select authentic Gruyère for authentic French onion taste and creamy texture that melts perfectly into the pasta.
• Stir pasta frequently during cooking and ensure enough liquid covers the noodles to avoid clumping or uneven cooking.
• Add broth gradually and maintain enough moisture to cook pasta without making the dish too soupy or too dry.
• Use fresh thyme or parsley right before serving to boost aromatic profile and add bright, vibrant flavor to the dish.
