One-Pot French Onion Chicken (Printable)

Tender chicken and caramelized onions meld with cheese in a comforting one-pot pasta dish.

# 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 oz short pasta (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 (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

# 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 6-8 minutes. Remove chicken and set aside.
02 - In the same pot, add remaining butter. Add sliced onions with a generous pinch of salt. Cook slowly over medium-low heat, stirring frequently, until onions are deeply caramelized and golden brown, approximately 20-25 minutes.
03 - Add minced garlic and thyme, sautéing for 1 minute until fragrant.
04 - Pour in white wine if using and scrape up browned bits from the bottom of the pot. Allow to reduce by half, approximately 2-3 minutes.
05 - Return seared 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 10-12 minutes.
07 - Stir in Gruyère and mozzarella cheese until melted and creamy. Adjust seasoning with additional salt and pepper as needed.
08 - Sprinkle with Parmesan cheese and broil under the oven for 2-3 minutes until golden and bubbly if desired. Serve hot, garnished with fresh thyme.

# Expert Advice:

01 -
  • Everything happens in one pot, which means fewer dishes and more time enjoying what you've made instead of washing up.
  • The caramelized onions create this deep, sweet backdrop that makes the whole dish taste like something you've perfected over years.
  • There's something magical about how the pasta absorbs all those flavors while the cheese melts in, turning it into pure comfort on a plate.
02 -
  • The timing of when you add the uncooked pasta is crucial; if the broth isn't hot when you add it, the pasta will cook unevenly and you'll end up with some mushy pieces and some crunchy ones.
  • Don't wander away once the pasta goes in because it absorbs liquid quickly and can stick to the bottom if you're not stirring occasionally; a burnt bottom layer ruins everything else.
03 -
  • If you don't have a Dutch oven, any large heavy-bottomed pot with a lid works; the key is that it distributes heat evenly so the onions caramelize without burning.
  • Thinly slice your onions by hand or with a mandoline instead of chopping them into chunks, because thin slices caramelize into that jammy texture you're after.
