How to Make Creamy Caramelized Onion Pasta

A 30-minute salmon rice bowl is easiest when the toppings are prepared first. The salmon needs only a few minutes in the skillet, so having the rice, vegetables, nori, and sauce ready keeps the meal moving.

Ingredients You’ll Need

• 12 oz rigatoni or other short pasta
• 3 large yellow onions, thinly sliced
• 2 tbsp unsalted butter
• 1 tbsp olive oil
• 1 tsp kosher salt
• 1 tsp granulated sugar
• 3 cloves garlic, minced
• 1 tsp fresh thyme leaves
• 1/2 cup dry white wine or low-sodium broth

• 1/2 tsp black pepper

How to Make French Onion Pasta

1. Cook the pasta in well-salted water until just shy of al dente. Reserve 1 cup pasta water, then drain.
2. Melt butter with olive oil in a large skillet over medium-low heat. Add onions, salt, and sugar. Cook 30 to 35 minutes, stirring often, until deeply golden and jammy.
3. Add garlic and thyme and cook for 1 minute. Pour in wine or broth, scraping up browned bits, and simmer until nearly evaporated.
4. Add broth and cream. Simmer 5 minutes, then stir in Gruyere and Parmesan until smooth.
5. Add pasta and toss until coated. Loosen with reserved pasta water as needed. Finish with black pepper and parsley.

Tips for the Best French Onion Pasta

• Keep the onions at medium-low heat so they caramelize rather than burn.
• Grate the cheese yourself for a smoother sauce.
• Reserve pasta water before draining; its starch helps the sauce cling.

Variations to Try

• Use Swiss or fontina instead of Gruyere.
• Add sliced mushrooms for extra savory flavor.
• Swap rigatoni for orecchiette or shells.

How to Store It

Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently with a splash of broth or water.
