Low Carb Chicken Spinach Mushroom (Printable)

Savory chicken casserole with mushrooms, spinach, and melted cheese in a rich creamy sauce.

# What You'll Need:

→ Proteins

01 - 4 boneless skinless chicken breasts (about 1.5 lbs)

→ Vegetables

02 - 8 oz cremini or white mushrooms, sliced
03 - 4 cups fresh baby spinach
04 - 2 cloves garlic, minced

→ Dairy

05 - 1 cup shredded mozzarella cheese
06 - 1/2 cup heavy cream

→ Pantry

07 - 2 tbsp olive oil
08 - 1/2 tsp salt
09 - 1/4 tsp ground black pepper

# How to Make It:

01 - Preheat oven to 400°F. Grease a 9x13-inch baking dish with cooking spray or a small amount of olive oil.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and sear for 2-3 minutes per side until golden brown. Transfer to a plate and set aside.
04 - In the same skillet, add sliced mushrooms. Sauté for 3-4 minutes until they release moisture and begin to brown. Add minced garlic and cook for 30 seconds until fragrant.
05 - Add fresh spinach to the skillet and toss with mushrooms. Cook for 1 minute until just wilted. Remove from heat.
06 - Arrange seared chicken breasts in the prepared baking dish. Spread the mushroom-spinach mixture evenly over the chicken.
07 - Pour heavy cream evenly over the chicken and vegetables. Sprinkle shredded mozzarella cheese across the top.
08 - Bake uncovered for 25-30 minutes until chicken is cooked through (internal temperature reaches 165°F) and cheese is golden and bubbly.
09 - Let the dish rest for 5 minutes before serving to allow the sauce to thicken slightly.

# Expert Advice:

01 -
  • Everything cooks in one pan before hitting the oven, so cleanup is surprisingly minimal
  • The cream sauce creates this velvety richness that feels indulgent despite being low carb
02 -
  • Do not skip searing the chicken first, that golden color adds depth of flavor you cannot get from baking alone
  • The cream will look thin going into the oven but it thickens beautifully as it bakes
03 -
  • Pat the chicken really dry before seasoning so it gets a proper sear instead of steaming in the pan
  • Let the mushrooms get some color before adding garlic, brown mushrooms equal more flavor
