Ingredients:

• 2 large yellow onions, thinly sliced
• ½ teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon sugar (optional, for quicker caramelization)
• 3 cloves garlic, minced
• 1 teaspoon dried thyme (or 1 tablespoon fresh thyme)
• 1 tablespoon balsamic vinegar (optional, for depth of flavor)
• 4 cups beef broth (or vegetable broth for a vegetarian version)
• 8 ounces uncooked pasta (fusilli, penne, or rigatoni work well)
• ½ cup heavy cream
• 1½ cups shredded Gruyère cheese
• ½ cup grated Parmesan cheese

How to Make One Pot French Onion Pasta:

Step 1: Caramelize the Onions

1. Heat butter and olive oil in a large pot or deep skillet over medium-low heat.
2. Add sliced onions, salt, pepper, and sugar (if using). Stir occasionally and cook for 25-30 minutes, or until onions are deep golden brown.
3. Add garlic and thyme, cooking for 1-2 minutes until fragrant.
4. Stir in balsamic vinegar to deglaze the pan.

Step 2: Cook the Pasta

5. Pour in beef broth and bring to a simmer.
6. Add pasta, stirring to ensure it’s submerged. Cover and cook on medium heat, stirring occasionally, until pasta is tender and most of the liquid is absorbed (10-12 minutes).

Step 3: Make it Creamy & Cheesy

7. Reduce heat to low and stir in heavy cream, Gruyère, and Parmesan until melted and creamy.
8. If the sauce is too thick, add a splash of broth or water.

Step 4: Serve & Enjoy

9. Garnish with fresh parsley or thyme and serve warm.

Serving Suggestions:

• Pair with crusty bread to soak up the creamy sauce.
• Serve alongside a simple green salad for balance.
• Add grilled chicken or steak for extra protein.

Tips for the Best French Onion Pasta:

Caramelize Slowly – The longer you cook the onions, the richer the flavor.
Use Good Cheese – Gruyère melts beautifully and gives that classic French onion taste.
Adjust the Sauce – If too thick, add a bit more broth or cream.
Make it Vegetarian – Use vegetable broth and swap Gruyère for a vegetarian cheese.

Storage & Reheating:

• Refrigerate in an airtight container for up to 3 days.
• Reheat on the stove over low heat, adding a splash of broth or cream if needed.
