Ingredients Method

Ingredients

  

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 3 large yellow onions, thinly sliced
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper
• 1 teaspoon sugar (optional, helps with caramelization)
• 2 cloves garlic, minced
• 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
• 1/4 cup dry white wine (optional, for deglazing)
• 3 cups beef or vegetable broth (low-sodium recommended)
• 8 ounces pasta (rigatoni, fusilli, or pappardelle work well)
• 1/2 cup heavy cream (or half-and-half for a lighter option)
• 1 cup shredded Gruyère (or Swiss; plus extra for topping)
• 1/4 cup grated Parmesan
• 1 tablespoon Worcestershire sauce (optional, adds umami)
• Fresh parsley, chopped, for garnish

Method

 

1. Prep the onions: Peel and thinly slice the onions from root to tip. Keep slices even so they cook uniformly.
2. Start caramelizing: In a large skillet or Dutch oven, heat the butter and olive oil over medium heat.Add the onions and salt, and cook, stirring every few minutes, until they soften and start to turn golden, about 10–12 minutes.
3. Deepen the color: Lower the heat slightly if the onions brown too quickly. Add sugar if using. Continue cooking, stirring occasionally and scraping the pan, until the onions are deeply caramelized and jammy, 25–35 minutes total.
4. Add aromatics: Stir in the garlic and thyme.Cook for 30–60 seconds until fragrant.
5. Deglaze: Pour in the white wine (if using). Scrape up browned bits from the bottom of the pan. Let the wine reduce by half, about 1–2 minutes.
6. Add broth: Stir in the broth and Worcestershire sauce.Bring to a gentle simmer.
7. Cook the pasta: Add the pasta directly to the skillet. Simmer, stirring often, until the pasta is al dente and the liquid has mostly absorbed, 10–12 minutes. Add more broth or water if it gets too dry before the pasta is done.
8. Make it creamy: Reduce heat to low.Stir in the heavy cream and let it warm through for 1–2 minutes.
9. Add cheese: Sprinkle in Gruyère and Parmesan. Stir until melted and silky. Taste and adjust with salt and pepper.
10. Serve: Top with a little extra Gruyère, a crack of pepper, and chopped parsley.Serve hot and enjoy the cozy, soup-like sauce clinging to every noodle.

How to Store

• Refrigerator: Store leftovers in an airtight container for up to 3–4 days. Reheat gently on the stove with a splash of broth or water to loosen the sauce.
• Freezer: Not ideal due to the dairy and pasta texture, but it can be frozen for up to 1 month. Thaw overnight and reheat slowly with added liquid.
• Make-ahead tip: Caramelize onions up to 3 days in advance and refrigerate.This shaves off most of the active time on a busy night.

Benefits of This Recipe

• Budget-friendly: Onions, broth, and pasta are inexpensive, and a little cheese goes a long way.
• Customizable: Works with chicken, mushrooms, or leftover roast beef. You can also switch up the cheese.
• Weeknight-ready: While onions take time, they’re hands-off. The rest comes together quickly in the same pan.
• Satisfying: Balanced with carbs, fat, and a savory depth that makes a modest portion feel filling.

Pitfalls to Watch Out For

• Rushing the onions: Turn the heat too high and they’ll burn before they caramelize.Keep it moderate and be patient.
• Over-salting early: If you’re using regular (not low-sodium) broth and Parmesan, salt at the end to avoid a salty dish.
• Clumpy cheese: Add cheese off the heat or on low. High heat can cause separation or stringiness.
• Dry pasta: The pasta absorbs a lot of liquid. Keep an eye on the pan and add splashes of broth or water as needed.

Alternatives

• Cheese swaps: Try Comté, Emmental, fontina, or a mild provolone if you can’t find Gruyère.
• Protein add-ins: Browned mushrooms, shredded rotisserie chicken, or seared steak slices make it heartier.
• Herb changes: Rosemary or a bay leaf (remove before serving) adds a different aromatic profile.
• Lighter version: Use half-and-half or whole milk instead of cream and reduce the cheese slightly.
• Vegetarian broth: Use a rich vegetable broth and skip Worcestershire or use a vegetarian version.
• Gluten-free: Use gluten-free pasta and check that your broth and Worcestershire are gluten-free.

FAQ

Can I use red onions instead of yellow?

Yes, but the flavor will be slightly different.

Yellow onions caramelize into a sweet, classic base. Red onions work in a pinch and give a deeper color and a slightly sharper finish.

Do I have to use wine?

No. Substitute with a splash of broth plus 1 teaspoon of apple cider vinegar or lemon juice.

The acidity helps balance the sweetness of the onions.

What pasta shape works best?

Short, ridged shapes like rigatoni or fusilli catch the sauce well. Wide noodles like pappardelle also shine. Avoid very delicate shapes that may overcook quickly.

How long should onions take to caramelize?

Usually 25–35 minutes over medium to medium-low heat.

The exact time depends on your pan and stove. They should be deep golden brown and jammy, not crispy or black.

Can I make this dairy-free?

Yes. Use olive oil instead of butter, a creamy unsweetened plant milk in place of cream, and a dairy-free melty cheese substitute or nutritional yeast for umami.

What if my sauce is too thin?

Let it simmer a few extra minutes to reduce, or stir in a small splash of cream and a bit more Parmesan to thicken.

Be careful not to overcook the pasta.

What if my sauce is too thick?

Add warm broth or water, a little at a time, until it loosens to a silky consistency. Stir well after each addition.

Can I bake it like French onion soup?

Absolutely. Transfer to an oven-safe dish, top with extra Gruyère, and broil until bubbly and browned.

Keep an eye on it so it doesn’t burn.

French onion pasta is the kind of cozy, rich comfort food that still feels simple and unfussy. With a handful of pantry staples and a little patience for the onions, you get deep, soulful flavor in every bite.
