One-Pot French Onion Chicken Pasta (Printable Version)

Cozy French-inspired dish with chicken, caramelized onions, and melted cheese in one pot comfort cooking.

# What You Need:

→ Proteins

01 - 2 large boneless, skinless chicken breasts (about 1.1 lbs), cut into bite-sized pieces

→ Vegetables

02 - 3 large yellow onions, thinly sliced
03 - 3 cloves garlic, minced
04 - 2 tablespoons fresh thyme leaves or 1 teaspoon dried thyme

→ Pasta

05 - 12 ounces short pasta such as penne, fusilli, or rigatoni

→ Broth & Liquids

06 - 3 tablespoons unsalted butter
07 - 2 tablespoons olive oil
08 - 4 cups low-sodium beef or chicken broth
09 - 1/2 cup dry white wine, optional or substitute with additional broth
10 - Salt and freshly ground black pepper to taste

→ Cheese

11 - 1 cup Gruyère cheese, shredded
12 - 1/2 cup mozzarella cheese, shredded
13 - 2 tablespoons grated Parmesan cheese

# How-To Steps:

01 - Heat olive oil and 1 tablespoon butter in a large Dutch oven or deep skillet over medium heat. Add chicken pieces, season with salt and pepper, and cook until golden and cooked through, approximately 6 to 8 minutes. Remove chicken and set aside.
02 - In the same pot, add remaining butter. Add sliced onions and a generous pinch of salt. Cook slowly over medium-low heat, stirring often, until onions are deeply caramelized and golden brown, approximately 20 to 25 minutes.
03 - Add minced garlic and thyme, then sauté for 1 minute until fragrant.
04 - Pour in white wine if using, and scrape up any browned bits from the bottom of the pot. Allow to reduce by half, approximately 2 to 3 minutes.
05 - Return cooked chicken to the pot. Add uncooked pasta and broth. Bring to a boil, then reduce heat to a simmer.
06 - Cover and cook, stirring occasionally, until pasta reaches al dente texture and most liquid has been absorbed, approximately 10 to 12 minutes.
07 - Stir in Gruyère and mozzarella cheese until melted and creamy. Season with additional salt and pepper as needed.
08 - Sprinkle with Parmesan cheese and, if desired, broil under the oven for 2 to 3 minutes until golden and bubbly.
09 - Serve hot, garnished with fresh thyme.

# Expert Tips:

01 -
  • Everything happens in one pot, which means less cleanup and more time savoring what you've made.
  • The caramelized onions taste like you spent hours on them, but the trick is knowing when to stop fussing and let the heat do the work.
  • It's one of those dishes that tastes like you're showing off, but it's honestly just smart timing.
02 -
  • Don't skimp on the caramelization time with the onions; rushing this step is the single biggest mistake that will make it taste like regular pasta instead of something special.
  • The pasta will continue absorbing liquid even after you turn off the heat, so if it looks a little saucier than you'd expect at the end of cooking, that's actually perfect.
03 -
  • If your onions aren't caramelizing as quickly as you'd like, increase the heat slightly; low and slow is ideal, but not so slow that they just steam instead of brown.
  • Taste the broth before you add it; if it's salty, use a little less than called for, because reduction will concentrate it further.
