Ingredients
  

Chicken breasts
  • 4 boneless skinless chicken breasts Pat dry before seasoning for better sear and browning.
Seasonings
  • 1 Salt Use enough to season generously on both sides of the chicken.
  • 1 pepper Cracked or fine pepper both work—use to taste.
  • 1 garlic powder Season chicken evenly for savory flavor in the cream sauce.
  • 1 onion powder Helps round out the seasoning layer.
Searing and flavor base
  • 2 tbsp olive oil For searing the chicken in the skillet.
  • 2 tbsp butter Adds richness when cooking mushrooms and building the sauce.
  • 8 oz cremini mushrooms Slice so they brown deeply and distribute throughout the sauce.
  • 4 cloves garlic Minced for quick browning and aromatic flavor.
  • 1 cup chicken broth Used to deglaze and create a smooth base for the cream sauce.
  • 1 cup heavy cream Simmered to thicken into a silky mushroom cream sauce.
  • 1 cup Parmesan cheese, grated Stir in until melted and the sauce turns glossy.
  • 1 tsp dried thyme Herb flavor in the sauce; complements mushrooms.
  • 1 tsp Italian seasoning Season the sauce for a classic weeknight profile.
  • 1 Fresh thyme and parsley for garnish Finishing garnish for fresh aroma and color.

Equipment

  • 1 cast iron skillet

Method
 

Season and sear the chicken
  1. Season the chicken breasts generously on both sides with salt, pepper, garlic powder, and onion powder.
  2. Heat olive oil in a large skillet over medium-high heat until shimmering, then sear chicken for 5-6 minutes per side until golden and the internal temperature reaches 165°F; remove to a plate.
Build the mushroom cream sauce
  1. Melt butter in the same skillet, then cook the sliced cremini mushrooms for 4-5 minutes until deeply golden.
  2. Add the minced garlic and cook for 1 minute, stirring, until fragrant but not browned.
  3. Pour in the chicken broth and deglaze the pan, scraping up browned bits from the bottom of the skillet.
  4. Stir in the heavy cream, Parmesan cheese, dried thyme, and Italian seasoning, then simmer for 4-5 minutes until the sauce thickens and looks glossy.
Finish and serve
  1. Return the chicken to the skillet and spoon the mushroom cream sauce over each breast so it pools around the edges.
  2. Garnish with fresh thyme and parsley right before serving.

Notes

Pro tip: If the chicken won’t brown well, make sure the breasts are patted dry and let the skillet get fully hot before searing. Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently so the sauce stays creamy. Freezing is not recommended because the cream sauce can break when thawed. Dietary swap: use half-and-half instead of heavy cream for a lighter sauce (thickness may be slightly less).
