Ingredients Notes

The beauty of One Pot French Onion Pasta lies in its simple ingredients that work together to create big flavor.

Onions

Sweet onions are the star of this dish. Their natural sugars caramelize during cooking, giving the pasta its signature rich, sweet flavor. Yellow onions also work well if that’s what you have on hand.

Butter

A generous amount of butter helps the onions caramelize to perfection and adds a luxurious richness to the dish.

Broth

Using beef broth gives this pasta the signature French onion soup flavor. For a vegetarian option, substitute with a rich vegetable broth.

Pasta

Long pasta like fettuccine or linguine works best for this dish, as it soaks up the flavorful sauce while maintaining a delightful texture.

Cheese

Gruyère cheese is the classic choice, providing a nutty, melty finish that ties the dish together. Parmesan or mozzarella can be used as alternatives.

Herbs and Aromatics

Fresh thyme and minced garlic elevate the dish with their earthy, aromatic notes, complementing the caramelized onions beautifully.

All you need is a large pot or deep skillet with a lid, and you’re ready to cook!

How To Make This One Pot French Onion Pasta

This recipe is simple, yet delivers incredible results. Follow these steps to create a dish that’s as comforting as it is delicious:

1. Caramelize the Onions
   In a large pot, melt butter over medium heat. Add thinly sliced onions and a pinch of salt, stirring occasionally. Let them cook until they’re soft and golden brown, about 20 minutes.
2. Add Garlic and Herbs
   Stir in minced garlic and a few sprigs of fresh thyme, cooking for another minute or until fragrant.
3. Deglaze the Pot
   Pour in a splash of white wine or broth, scraping up the browned bits at the bottom of the pot. These bits are packed with flavor!
4. Cook the Pasta
   Add uncooked pasta and broth to the pot. Bring the mixture to a boil, then reduce the heat to a simmer. Cover and cook, stirring occasionally, until the pasta is tender and the liquid has thickened into a sauce.
5. Add the Cheese
   Reduce the heat to low and stir in shredded Gruyère cheese until it melts into the sauce, creating a creamy, cheesy coating.
6. Serve and Enjoy
   Garnish with fresh parsley or a sprinkle of Parmesan for extra flair. Serve immediately with a side of crusty bread or a green salad.

Storage Options

Refrigerator

Store the pasta in an airtight container for up to 3 days. Reheat on the stovetop or in the microwave, adding a splash of broth or water to loosen the sauce.

Freezer

While this dish is best enjoyed fresh, you can freeze it in a freezer-safe container for up to 2 months. Let it thaw overnight in the fridge before reheating.

Reheating Tip

To keep the cheese smooth and melty, reheat the pasta gently over low heat, stirring frequently.

Vegetarian Option

Swap the beef broth for a rich vegetable broth and ensure your cheese is vegetarian-friendly.
