Chicken and Mushroom Skillet in a Creamy Asiago and Mustard Sauce

Ingredients

Ingredient Quantity
Boneless, skinless chicken breasts 4
Salt and pepper To taste
Olive oil 2 tbsp (divided)
Unsalted butter 1 tbsp
Cremini or button mushrooms, sliced 8 oz
Garlic, minced 3 cloves
Chicken broth ½ cup
Heavy cream 1 cup
Asiago cheese, grated ½ cup
Dijon mustard 2 tbsp
Fresh thyme leaves (or dried thyme) 1 tsp (or ½ tsp dried)
Fresh parsley, chopped (for garnish) As desired

Directions

Season and Sear the Chicken:
Pat the chicken breasts dry and season both sides with salt and pepper. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Place the chicken in the skillet and cook for 5–7 minutes per side, or until they’re golden brown and cooked through. Transfer the chicken to a plate and set aside.

Cook the Mushrooms:
Add the remaining olive oil and the butter to the same skillet. Once the butter melts, toss in the sliced mushrooms and sauté for 5–6 minutes, stirring occasionally, until they’re browned and tender. Add the minced garlic and cook for another 1–2 minutes until fragrant.

Deglaze with Broth:
Pour in the chicken broth and use a wooden spoon to scrape up any flavorful browned bits from the bottom of the skillet. Let the liquid simmer for 2–3 minutes, allowing it to reduce slightly.

Make the Creamy Sauce:
Lower the heat to a gentle simmer. Stir in the heavy cream, grated Asiago cheese, Dijon mustard, and thyme. Stir continuously until the cheese has melted and the sauce turns smooth and silky. Taste and adjust the seasoning with more salt and pepper if needed.

Combine and Finish Cooking:
Return the chicken breasts to the skillet, nestling them into the sauce. Spoon the creamy mixture over the top and let the dish simmer for 3–5 minutes so the flavors meld and the chicken warms through.

Garnish and Serve:
Sprinkle with fresh parsley for a bright finish. This dish pairs beautifully with mashed potatoes, pasta, or roasted vegetables for a complete and satisfying meal.

This creamy Asiago chicken skillet is flavorful, elegant, and incredibly simple—perfect for both a quick weeknight dinner or a dish to impress guests without spending hours in the kitchen.
