How to Make French Onion Chicken Thighs: Step By Step
Here are some quick visual instructions. The full instructions and ingredient list will be in the printable recipe card below!
- Prep and sear chicken. Pat the chicken thighs dry with a paper towel. Season with herbs de Provence, kosher salt, and freshly ground black pepper. Heat a large skillet over medium heat with olive oil. Sear the chicken for 3-4 minutes on each side until lightly golden brown. Remove from the skillet and transfer to a bowl.
- Make caramelized onions. Add 1 tablespoon of butter and the sliced onions to the skillet. Stir to combine then spread them out and let cook undisturbed for 5-7 minutes. Season with a pinch of salt. When they’re starting to stick, deglaze the pan with 2 tablespoons of broth while scraping the bottom of the pan to help break up the browned bits (fond). Continue with this process until you’ve deglazed the onions three times and the onions have turned a deep brown color.
- Add aromatics. Once the onions are finished cooking, stir in the fresh thyme and minced garlic and cook for an additional 2-3 minutes.
- Add cream sauce. Combine the remaining 1 cup of chicken broth, coconut milk, and nutritional yeast in a bowl then pour it into the caramelized onions. Stir to combined then nestle the seared chicken thighs in the sauce.
- Finish cooking. Cover the skillet with a lid. Reduce to medium-low heat and cook for 7-9 minutes or until a meat thermometer reads an internal temperature of 165ºF.
- Serve. Serve the chicken thighs with cauliflower mash or mashed potatoes, cooked pasta, white rice, crusty bread, etc. Spoon some of the creamy sauce from the skillet over the top and garnish with fresh herbs on top.
Helpful Tips
- Yellow onions are my go-to. They’re so versatile and readily available. Plus, they caramelize nicely. However, you can also use white onions, vidalia onions, or red onion
- Avoid high heat. You’ll end up with burnt onions instead of caramelized onions.
- If your skillet doesn’t have a lid, you can also cover it with a sheet pan. Just be careful removing it because it gets extremely hot.
Quick Tip: A stainless steel or cast iron pans work best for caramelizing onions.
Storage
Store leftovers in an airtight container in the fridge for 3-4 days.
Make It Your Way: Substitutions & Variations
Please remember that recipes are just a starting point.
How can you make this french onion chicken recipe using what you already have? Here are some ideas…
- No boneless skinless chicken thighs? – you can use bone-in thighs but you’ll need to cook them longer. If using boneless skinless chicken breasts (about 1.25 pounds) cook them for less time so they don’t overcook.
- No herbs de Provence? – any dried herbs are fine.
- Add ins – sliced mushrooms or white wine for more depth of flavor.
Frequently Asked Questions
I like to serve them over cauliflower mash or mashed sweet potatoes but you could also serve them with a side of green beans or quick sauteed broccoletti.
It’s delicious without cheese, but you can if you’d like. For dairy free, I’d recommend Daiya’s smoked gouda cheese. If not dairy free, use Swiss or gruyere cheese.
