🛒 Ingredients

Serves 4

For the chicken

  • 4 boneless, skinless chicken breasts
  • 2 tbsp olive oil
  • 1 tsp garlic powder
  • ½ tsp paprika
  • ½ tsp Italian seasoning
  • ½ tsp salt
  • ½ tsp black pepper

For the mushroom spinach sauce

  • 2 tbsp butter
  • 8 oz (225 g) mushrooms, sliced
  • 4–5 cloves garlic, minced
  • ½ cup chicken broth
  • 1 cup heavy cream
  • ½ cup freshly grated Parmesan cheese
  • 3 cups fresh baby spinach
  • ½ tsp Italian seasoning
  • ¼ tsp black pepper
  • Salt to taste
  • 1 tbsp fresh parsley, chopped
  • 1 tbsp lemon juice, optional

👩‍🍳 Step-by-Step Instructions

1. Prepare the chicken

If the chicken breasts are thick, slice them horizontally into thinner cutlets. This helps them cook evenly and stay juicy.

Pat them dry with paper towels.

Season both sides with garlic powder, paprika, Italian seasoning, salt, and black pepper.

2. Sear the chicken

Heat 2 tbsp olive oil in a large skillet over medium-high heat.

Add the chicken and cook for about 4–5 minutes per side, until beautifully golden and cooked through.

The internal temperature should reach 165°F (74°C).

Transfer the chicken to a plate and loosely cover it with foil.

3. Cook the mushrooms

Reduce the heat to medium and add 2 tbsp butter to the same skillet.

Add the sliced mushrooms.

Cook for 5–7 minutes, stirring occasionally, until the mushrooms become golden brown and most of their liquid has cooked away.

Don’t rush this step—the browned mushrooms give the sauce much more flavor.

4. Add the garlic

Add the minced garlic and cook for about 30–60 seconds.

Stir constantly so the garlic becomes fragrant without burning.

5. Make the creamy sauce

Pour in the ½ cup chicken broth.

Use your spatula to scrape the browned bits from the bottom of the pan. That’s where a lot of the flavor is!

Let it simmer for about 2 minutes.

Then slowly add the 1 cup heavy cream.

Stir well.

6. Add Parmesan

Reduce the heat to low.

Add:

  • ½ cup Parmesan
  • ½ tsp Italian seasoning
  • ¼ tsp black pepper

Stir until the Parmesan melts and the sauce becomes smooth and creamy.

Let it gently simmer for 2–4 minutes until slightly thickened.

7. Add the spinach

Add the fresh spinach a handful at a time.

Stir gently until it wilts into the creamy mushroom sauce, about 1–2 minutes.

Don’t overcook it—the spinach should remain bright green.

8. Return the chicken

Place the cooked chicken back into the skillet.

Spoon the creamy garlic mushroom sauce over each piece.

Let everything simmer together on low for 2–3 minutes so the chicken absorbs the sauce.

9. Finish

Turn off the heat.

Add 1 tbsp lemon juice if you like a little brightness.

Sprinkle with fresh parsley and a little extra Parmesan.

🧀 Extra-Creamy Version

For an even richer sauce, add 2 oz cream cheese along with the heavy cream.

Stir until completely melted and smooth.

🌶️ Optional Additions

You can also add:

  • Red pepper flakes for heat
  • Sun-dried tomatoes
  • Crispy bacon
  • Mozzarella
  • A little sliced onion
  • Fresh thyme
  • Extra Parmesan

🥦 Keto Serving Ideas

Serve it with:

  • Cauliflower rice
  • Steamed broccoli
  • Zucchini noodles
  • Roasted asparagus
  • Sautéed green beans
  • A simple green salad

If you’re not following keto, it is also delicious over pasta, rice, or mashed potatoes.

❄️ Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheat gently over low heat. If the sauce becomes too thick, add a splash of chicken broth or cream while reheating.

⭐ Best Tip

Don’t overcrowd the pan when browning the mushrooms. Give them enough room to actually brown instead of steaming. That little extra step makes a HUGE difference in the flavor of this dish. 🍄🧄😋
