Step‑by‑Step Instructions for Low-Carb Chicken Spinach Mushroom Bake

Step 1: Prep Chicken
Start by patting your boneless, skinless chicken breasts or thighs dry with paper towels. This will ensure a proper sear. In a mixing bowl, season the chicken generously with salt, pepper, Italian seasoning, and paprika. Let it sit while you prepare your skillet, allowing the flavors to meld and the chicken to reach room temperature, about 10 minutes.

Step 2: Sear Chicken
Heat a skillet over medium-high heat and add a tablespoon of olive oil. Once the oil is shimmering, place the seasoned chicken in the skillet and sear for 1-2 minutes on each side until lightly golden. This quick browning enhances the flavor and locks in moisture. Transfer the seared chicken to a plate and set aside while you work on the mushrooms.

Step 3: Sauté Mushrooms
In the same skillet, add another tablespoon of olive oil and a pat of butter. Allow the butter to melt, then add the sliced mushrooms along with a pinch of salt. Sauté the mushrooms for about 5-6 minutes until they are nicely browned and have released their juices. Stir in minced garlic, cooking for an additional 30 seconds until fragrant, and let the aromatic goodness fill your kitchen.

Step 4: Make Sauce
Deglaze the skillet by pouring in chicken broth, scraping up any browned bits stuck to the bottom. Let the broth simmer and reduce for 1 minute before stirring in the heavy cream, Dijon mustard, red pepper flakes, and freshly cracked pepper. Add the Parmesan cheese, stirring continuously until the mixture thickens slightly—this becomes the luscious sauce for your Low-Carb Chicken Spinach Mushroom Bake.

Step 5: Add Spinach
Now, add the fresh spinach to the skillet, stirring until it wilts down. This will only take a minute. Taste the sauce and adjust the seasoning if necessary, then nestle your seared chicken back into the creamy mixture. If your skillet isn’t oven-safe, transfer everything into a baking dish, ensuring the chicken is evenly coated with that heavenly sauce.

Step 6: Bake
Preheat your oven to 400°F (200°C). Top the chicken and sauce with shredded mozzarella and any remaining Parmesan cheese. Bake in the preheated oven for 18-22 minutes, until the cheese is melted and bubbly, and the chicken has reached an internal temperature of 165°F. For a golden-brown finish, broil for an additional 1-2 minutes.

Step 7: Rest & Serve
Once baked to perfection, remove the dish from the oven and let it rest for about 5 minutes. This resting time allows the flavors to settle. Serve your enticing Low-Carb Chicken Spinach Mushroom Bake garnished with chopped parsley or chives for a fresh touch, and enjoy the comforting flavors of this delightful meal!
