Ingredients Notes

The beauty of One Pot French Onion Pasta lies in its simple yet flavorful ingredients. Each one is carefully chosen to bring out that signature French onion taste.

• Onions: Sweet or yellow onions are key here. They caramelize beautifully, providing the sweet, rich flavor that’s central to this dish. Slice them thin for even cooking.
• Pasta: Long noodles like fettuccine or linguine work best, as they soak up the sauce while retaining a perfect bite. If you have spaghetti on hand, that works too!
• Beef or Vegetable Broth: This forms the base of your sauce and mimics the broth in French onion soup. Use a high-quality broth for the best flavor.
• Butter: A few tablespoons of butter help the onions caramelize and add richness to the dish.
• Cheese: Gruyère is the traditional choice for French onion soup, but Parmesan or mozzarella can work in a pinch.
• Thyme and Garlic: Fresh thyme and minced garlic add layers of herby, aromatic goodness to complement the onions.

You’ll also need a large, deep skillet or pot with a lid to cook everything in one go.

How To Make This One Pot French Onion Pasta

Creating this delicious pasta dish is easier than you might think. Let me walk you through the process step by step.

1. Caramelize the onions. Start by melting butter in a large pot over medium heat. Add your sliced onions and cook, stirring occasionally, until they’re golden brown and caramelized. This step takes about 15-20 minutes but is worth every second for the rich flavor it develops.
2. Add aromatics and deglaze. Stir in minced garlic and a few sprigs of fresh thyme, cooking just until fragrant. Then pour in a splash of white wine or broth to deglaze the pan, scraping up all those flavorful browned bits from the bottom.
3. Cook the pasta. Add the uncooked pasta to the pot along with your broth. Bring the mixture to a simmer, cover, and let it cook until the pasta is tender. Stir occasionally to ensure even cooking and prevent sticking.
4. Finish with cheese. Once the pasta is done, reduce the heat and stir in shredded Gruyère cheese. It will melt into the sauce, creating a creamy, cheesy coating for the noodles.
5. Serve and enjoy! Garnish with fresh parsley or additional thyme, and serve hot. Pair it with a crisp green salad or some crusty bread for a complete meal.

From start to finish, this dish takes about 35 minutes, making it a perfect choice for busy evenings.

Storage Options

Have leftovers? This pasta stores beautifully, making it a great option for meal prep or next-day lunches.

• Refrigerator: Store the pasta in an airtight container for up to 3 days. Reheat in the microwave or on the stovetop, adding a splash of broth to loosen the sauce.
• Freezer: While this pasta can be frozen, it’s best enjoyed fresh or refrigerated. If you do freeze it, use a freezer-safe container and thaw overnight in the fridge before reheating.

Pro Tip: To keep the cheese from clumping during reheating, warm it slowly over low heat while stirring.

Variations and Substitutions

One of the best things about this recipe is how adaptable it is. Here are a few ways to switch things up:

• Vegetarian Version: Swap the beef broth for vegetable broth and ensure your cheese is vegetarian-friendly.
• Add Protein: Stir in cooked shredded chicken, ground beef, or sautéed mushrooms for extra heartiness.
• Try Different Cheeses: While Gruyère is traditional, you can experiment with sharp cheddar, fontina, or even brie for a unique twist.
• Gluten-Free Option: Use your favorite gluten-free pasta and double-check that your broth is gluten-free.
• Extra Veggies: Add spinach, kale, or roasted cherry tomatoes for a burst of color and nutrition.

Feel free to experiment and make this recipe your own. No matter how you customize it, it’s sure to become a family favorite.
