How to Make Creamy French Onion Chicken Skillet

Season Chicken: Pat chicken dry, then sprinkle salt and pepper evenly. Let rest briefly so flavors adhere and the meat browns beautifully during searing.
Sear Chicken: Heat olive oil in a skillet over medium-high heat until shimmering. Add breasts and cook 4–5 minutes per side until golden brown crust forms.
Caramelize Onions: Reduce heat to low, add butter and sliced onions. Cook 15–20 minutes, stirring occasionally, until onions turn deep golden brown and sweetly fragrant.
Add Garlic & Thyme: Stir in minced garlic and fresh thyme leaves for 1–2 minutes until fragrant, being careful not to let garlic brown too quickly.

For the Creamy Sauce:

Deglaze Skillet: Pour in chicken broth and Dijon mustard, scraping up browned bits. Bring to a gentle simmer for about 2 minutes to meld flavors.
Stir in Cream: Add heavy cream, stirring gently. Simmer 3–4 minutes until sauce thickens and coats the back of a spoon in a silky, ivory-colored finish.
Return Chicken: Nestle seared breasts back into sauce, spooning sauce over top. Cook 5 minutes more, or until internal temperature reaches 165°F and juices run clear.

Optional: Garnish with extra thyme sprigs or chopped parsley.
