Keto Creamy Spinach Mushroom Chicken (Printable)

Tender chicken with creamy spinach and mushrooms in a savory one-pan skillet.

# Ingredient List:

→ Chicken

01 - 4 boneless, skinless chicken breasts (approximately 1.3 lbs)
02 - 1 teaspoon salt
03 - 1/2 teaspoon black pepper
04 - 1/2 teaspoon garlic powder

→ Vegetables

05 - 2 tablespoons olive oil
06 - 8 oz cremini or white mushrooms, sliced
07 - 3 cups fresh spinach
08 - 3 cloves garlic, minced

→ Sauce

09 - 1 cup heavy cream
10 - 2 oz cream cheese, softened
11 - 1/3 cup grated Parmesan cheese
12 - 1/4 teaspoon ground nutmeg, optional
13 - 1/4 teaspoon red pepper flakes, optional

→ Garnish

14 - Fresh parsley, chopped, optional

# How to Make:

01 - Pat chicken breasts dry with paper towels and season both sides generously with salt, pepper, and garlic powder.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and cook for 5 to 6 minutes per side until golden brown and cooked through. Transfer to a plate and cover loosely with foil.
03 - In the same skillet, add sliced mushrooms and sauté for 4 to 5 minutes, stirring occasionally, until softened and lightly browned.
04 - Add minced garlic to the skillet and cook for 30 seconds, stirring constantly, until fragrant.
05 - Reduce heat to medium-low. Pour in heavy cream, add cream cheese and Parmesan cheese, stirring continuously until the cream cheese melts and the sauce becomes smooth.
06 - Add ground nutmeg and red pepper flakes if desired. Simmer gently for 2 to 3 minutes, stirring occasionally, until the sauce reaches desired thickness.
07 - Stir in fresh spinach and cook for 1 to 2 minutes, stirring frequently, until completely wilted.
08 - Return seared chicken breasts to the skillet and spoon sauce and vegetables over the top. Simmer for 2 to 3 minutes until chicken is heated through.
09 - Transfer to serving plates and garnish with chopped fresh parsley if desired. Serve immediately while hot.

# Expert Tips:

01 -
  • It's a complete dinner in one skillet—no sides needed unless you really want them, which saves on cleanup and thinking about what goes with what.
  • The sauce is genuinely creamy without feeling heavy, and somehow tastes like you spent way more time on it than you actually did.
  • Keto-friendly means no guilt, and it's the kind of dish that actually makes you feel satisfied rather than like you're depriving yourself.
02 -
  • Don't skip patting the chicken dry—this is the difference between a proper sear and steamed chicken, and I learned this the hard way by getting pale, rubbery results my first few tries.
  • If your cream cheese lumps up, it's because the heat was too high or you added it to boiling cream; lower the heat to medium-low and add it in small chunks, stirring constantly until it disappears.
  • The spinach must go in last, just before the chicken returns, because if it cooks too long it loses its vibrant color and can taste slightly metallic.
03 -
  • Add a tablespoon of butter along with the olive oil when searing the chicken for extra richness and more pronounced browning from the milk solids in the butter.
  • If you're sensitive to heat, skip the red pepper flakes, but do use the nutmeg—it adds a subtle sophistication that people taste without being able to identify exactly what it is.
