One Pot French Onion Pasta Ingredients

For the Pasta
Orecchiette – A charming pasta shape that holds sauce wonderfully; feel free to swap it for radiatori, rotini, or shells for variety.

For the Base
Yellow Onions – The backbone of flavor; caramelizing them brings out their natural sweetness, so slice them into consistent 1/8-inch rings for best results.
Garlic – Infuses a rich aroma; if you’re in a pinch, 1 teaspoon of garlic powder can step in just fine.
Water + Beef Bouillon – Creates a mouthwatering broth; using beef broth enhances the depth of flavor beautifully.
Evaporated Milk – Essential for achieving that creamy texture; don’t replace it with regular milk as it won’t yield the same result.
Worcestershire Sauce – Adds a delightful umami kick that elevates the taste significantly.
Soy Sauce – Opt for reduced sodium to keep the dish balanced while adding that extra layer of flavor.

For Seasoning
Fresh Thyme & Parsley – Provide a burst of freshness; if fresh isn’t available, dried herbs can do the trick.
Dried Oregano, Paprika, & Red Pepper Flakes – Season to your taste; these spices bring warmth and complexity to the dish.

For the Cheese
Gruyere Cheese – Adds a sweet, nutty flavor that’s simply irresistible; you can swap it for Swiss cheese if preferred.
Parmesan Cheese – Brings a salty contrast to the sweet onions, making it the perfect finishing touch; fresh-grated is always best!

Step‑by‑Step Instructions for One Pot French Onion Pasta

Step 1: Caramelize Onions
In a large pot, melt 2 tablespoons of butter and 2 tablespoons of olive oil over medium heat. Add 4 sliced yellow onions, stirring occasionally for 30-35 minutes until they become golden brown and caramelized, releasing their sweet aroma that fills your kitchen.

Step 2: Add Garlic and Seasonings
Stir in 4 minced garlic cloves along with a pinch of red pepper flakes, and sauté for about 30 seconds until fragrant. Next, mix in 1 tablespoon of Worcestershire sauce and 1 tablespoon of soy sauce, allowing the mixture to simmer for an additional minute, enhancing the savory depth of your One Pot French Onion Pasta.

Step 3: Combine Liquids
Pour in 4 cups of water along with half of a 12-ounce can of evaporated milk. In a separate bowl, mix 2 tablespoons of cornstarch with the remaining evaporated milk until smooth, then add this to the pot, stirring to combine everything into a delicious, creamy base.

Step 4: Boil Pasta
Bring the liquid to a rolling boil, and once bubbling, add 12 ounces of orecchiette pasta. Reduce the heat to a gentle simmer, cover the pot, and cook for about 20-25 minutes, stirring occasionally, until the pasta is al dente and has absorbed the flavors.

Step 5: Finish with Cheese
Remove the pot from heat and stir in 1 cup of shredded Gruyere cheese and ½ cup of freshly grated Parmesan cheese until melted and creamy. Taste and adjust the seasonings as needed before serving your comforting One Pot French Onion Pasta hot, savoring the rich fusion of flavors.

Make Ahead Options

Preparing the One-Pot French Onion Pasta in advance is a fantastic way to save time during those busy weeknights! You can caramelize the onions and garlic up to 24 hours ahead of time; simply store them in an airtight container in the refrigerator. Additionally, measure out your seasonings and combine liquids, keeping them refrigerated until you’re ready to cook. When you’re set to enjoy your meal, just bring the mixture to a boil, stir in the uncooked orecchiette, and proceed with the recipe as usual. This way, you’ll have a comforting dish that tastes just as delicious with minimal effort!
