Instructions

  1. Step 1: Pat chicken breasts dry with paper towels and season both sides with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 5-6 minutes per side until golden brown and internal temperature reaches 165°F, then transfer to a plate and tent with foil.
  3. Step 3: Add remaining 1 tbsp olive oil to the skillet, then add sliced mushrooms and cook for 4-5 minutes until they release liquid and brown slightly.
  4. Step 4: Add minced garlic and cook for 1 minute until fragrant, then pour in 1/2 cup chicken broth and scrape up browned bits from the pan.
  5. Step 5: Stir in 1/2 cup heavy cream and 1 tsp chopped thyme, then simmer for 3-4 minutes until sauce thickens and coats the back of a spoon.
  6. Step 6: Return chicken to skillet, spoon sauce over top, and cook for 1-2 minutes to heat through.

Frequently asked questions

How long does Pan-Seared Chicken with Garlic Mushroom Sauce take to make?

Total time is about 35 minutes (15 min prep + 20 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Seared Chicken with Garlic Mushroom Sauce?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep chicken breast from drying out.

Can I substitute ingredients in Pan-Seared Chicken with Garlic Mushroom Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Chicken with Garlic Mushroom Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Pan-Seared Chicken with Garlic Mushroom Sauce?

American keto like this pair well with a low-carb side — cauliflower rice, roasted broccoli or asparagus, or a leafy salad with olive oil and parmesan. Rice, couscous and bread would blow the carb budget this recipe is built around. Tap "Plan a meal with the AI" to get specific side suggestions.
