Step‑by‑Step Instructions for One Pot French Onion Pasta
Step 1: Slice the Onions
Begin by thinly slicing 2–3 yellow onions into 1/8-inch rings. These will form the flavorful base of your One Pot French Onion Pasta. Use a sharp knife for even cuts that helps with cooking time consistency. Set your sliced onions aside as they will become sweet and caramelized during cooking.
Step 2: Caramelize Onions
In a large Dutch oven, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium heat. Add your sliced onions and cook them, stirring occasionally, for about 30–35 minutes. Keep a close eye on them; you want the onions to turn a lovely dark golden brown, developing their natural sweetness without burning.
Step 3: Add Garlic and Seasonings
Once the onions are beautifully caramelized, stir in 4 minced garlic cloves along with a pinch of red pepper flakes, 1 tablespoon of soy sauce, and 2 tablespoons of Worcestershire sauce. Sauté this mixture for about 30 seconds until fragrant. This adds depth and complexity to your One Pot French Onion Pasta.
Step 4: Combine Liquids
Next, pour in 4 cups of water and half of a 12-ounce can of evaporated milk into the pot. Whisk together the remaining evaporated milk with 1 tablespoon of cornstarch until smooth, then add it to the pot. This combination will create a creamy broth that enhances the pasta and onion flavors.
Step 5: Boil Pasta
Bring the mixture to a rolling boil before adding 12 ounces of orecchiette pasta. Reduce the heat to a simmer and cook uncovered for 20–25 minutes. Stir the pasta frequently until it’s al dente and has absorbed most of the liquid, creating a luscious sauce that wraps around each piece of pasta.
Step 6: Incorporate Cheese
Once the pasta is cooked, remove the pot from heat and gradually mix in 1 cup of grated Gruyere cheese and 1/2 cup of freshly grated Parmesan cheese. Stir until the cheese is completely melted and the sauce is creamy. Taste and season with salt and pepper if needed to elevate your One Pot French Onion Pasta to perfection.

One-Pot French Onion Pasta Recipe FAQs
How do I choose the right onions for this recipe?
Absolutely! Opt for yellow onions as they caramelize beautifully and provide the sweet, deep flavor that defines French onion dishes. Look for firm onions without dark spots or soft areas. A slight golden or brown sheen is a good sign of freshness. Avoid any onions that have sprouted, as they can taste bitter.

What can I do if my onions aren’t caramelizing properly?
If your onions aren’t caramelizing as expected, make sure you’re cooking them over medium heat. This allows for the slow release of sugars, which is crucial for perfect caramelization. Stir them every few minutes to ensure even cooking and prevent burning. If they seem to be cooking too slowly, a pinch of salt can draw out moisture and help them along.
Is there a gluten-free option for this recipe?
Very much so! To adapt your One-Pot French Onion Pasta for gluten-sensitive diets, simply swap the regular orecchiette for gluten-free pasta. There are various delicious gluten-free options available nowadays, like those made from rice or chickpeas, which can still hold up well in this creamy dish.
Are there any potential allergens in this recipe I should be aware of?
Yes, the recipe contains common allergens like dairy (from the Gruyere and Parmesan cheese) and gluten (from the pasta). If you’re cooking for someone with these allergies, you might consider using dairy-free cheese alternatives and gluten-free pasta. Always double-check labels for any hidden allergens, especially with pre-packaged ingredients like broth or sauces.
