Ingredients

  • 4 boneless, skinless chicken breasts or thighs
  • 8 oz (225 g) mushrooms, sliced
  • 2 large onions, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 1 teaspoon dried thyme
  • ½ teaspoon paprika
  • ½ cup chicken broth
  • Salt, to taste
  • Black pepper, to taste
  • Fresh parsley, for garnish

How to Make Skillet Chicken with Mushrooms and Caramelized Onions

1. Season the Chicken

Pat the chicken dry and season both sides with salt, black pepper, paprika, and thyme.

2. Brown the Chicken

Heat a large skillet over medium-high heat and add the olive oil.

Place the chicken in the skillet and cook until nicely browned on both sides and cooked through. Transfer the chicken to a plate and set aside.

3. Caramelize the Onions

Reduce the heat to medium and add the butter to the same skillet.

Add the sliced onions and cook slowly, stirring occasionally, until they become soft and deeply golden. This can take around 15–20 minutes.

If the onions begin sticking, add a small splash of chicken broth and continue cooking.

4. Cook the Mushrooms

Add the sliced mushrooms and minced garlic to the skillet.

Cook for several minutes until the mushrooms soften and release their moisture. Stir occasionally so the vegetables cook evenly.

5. Bring Everything Together

Pour in the chicken broth and scrape the flavorful browned bits from the bottom of the skillet.

Return the cooked chicken to the pan. Spoon some of the onions and mushrooms over the chicken.

Simmer gently for a few minutes so the flavors can come together and the chicken is heated through.

6. Garnish and Serve

Taste and adjust the seasoning if needed.

Sprinkle with fresh parsley and serve warm.

Helpful Tips

Take Your Time with the Onions

The onions are an important part of this recipe. Cooking them slowly allows them to become soft, golden, and naturally sweet.

Don’t Crowd the Chicken

If your skillet is small, brown the chicken in batches. Giving each piece enough space helps it develop better color.

Use the Same Skillet

Cooking the onions and mushrooms in the same skillet used for the chicken helps incorporate the flavorful browned bits into the sauce.

Check the Chicken

Chicken should be cooked thoroughly before serving. For the most reliable result, check the thickest part with a food thermometer.

Easy Variations

You can customize this skillet dinner to suit your taste.

Try adding a splash of cream for a richer sauce, spinach for extra vegetables, or fresh herbs such as thyme or parsley.

For a deeper flavor, a small splash of balsamic vinegar can also complement the caramelized onions.

Frequently Asked Questions

Can I use chicken thighs?

Yes. Boneless, skinless chicken thighs work very well and can provide a particularly tender result.

Can I use different mushrooms?

Absolutely. Cremini, white button, or baby bella mushrooms are all good choices.

Can I prepare this recipe ahead of time?

Yes. The cooked dish can be refrigerated and gently reheated. Store leftovers properly and reheat thoroughly before serving.

How do I keep the onions from burning?

Cook them over medium to medium-low heat and stir regularly. If the pan becomes too dry, add a small splash of broth or water.
