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

Step 1: Prep Chicken
Begin by patting your boneless, skinless chicken breasts dry and seasoning them generously with salt, pepper, Italian seasoning, and paprika. Allow the seasoned chicken to marinate for about 10 minutes. This step helps lock in flavor and ensures that every bite of your Low-Carb Chicken Spinach Mushroom Bake is succulent and delicious.

Step 2: Sear Chicken
Heat a large oven-safe skillet over medium-high heat and drizzle in some olive oil. Once the oil shimmers, add the marinated chicken, cooking for 1-2 minutes on each side until it’s lightly browned. The chicken should develop a nice golden color; then, remove it from the skillet and set it aside while you prepare the vegetables.

Step 3: Sauté Veggies
In the same skillet, add a touch more olive oil and a bit of butter to enhance flavor. Toss in the sliced cremini mushrooms, sautéing for 5-6 minutes until they soften and release their moisture. Once the mushrooms are browned, add minced garlic, cooking for an additional minute until fragrant, stirring frequently to prevent burning.

Step 4: Make Sauce
Pour in the chicken broth to deglaze the skillet, scraping up any browned bits from the bottom. Next, stir in the heavy cream and grated Parmesan cheese, allowing the mixture to simmer for 3-5 minutes until it thickens slightly. You want the sauce to coat the back of a spoon, adding creaminess to your Low-Carb Chicken Spinach Mushroom Bake.

Step 5: Add Spinach
Fold in the fresh baby spinach, stirring gently until it wilts down and integrates into the sauce. Taste and adjust the seasoning with salt and pepper as needed. Once fully combined, return the seared chicken to the skillet, or if preferred, transfer everything to a greased baking dish for the next step.

Step 6: Bake
Preheat your oven to 400°F (200°C) while you prep for baking. If in a skillet, simply sprinkle more mozzarella and the remaining Parmesan over the dish. If in a baking dish, cover the top with cheese. Bake in the preheated oven for 18-22 minutes until the top is bubbly and golden, creating a wonderful crust for your Low-Carb Chicken Spinach Mushroom Bake.

Step 7: Rest & Serve
After removing the bake from the oven, let it rest for about 5 minutes to settle the flavors. Consider garnishing with freshly chopped herbs like parsley or basil before serving. This resting time allows the delightful creamy sauce to meld perfectly with the chicken and vegetables, ensuring a satisfying meal.

Easy Low-Carb Chicken Spinach Mushroom Bake Recipe FAQs

How do I choose the right chicken for this recipe?
Absolutely! For the best results, use boneless, skinless chicken breasts for tenderness, but if you prefer a richer flavor, chicken thighs can be a great substitute. Just make sure, whether you use breasts or thighs, they are uniform in size for even cooking.

How should I store leftovers of the bake?
Very! Once your Low-Carb Chicken Spinach Mushroom Bake has cooled completely, transfer it to an airtight container and refrigerate. It will stay fresh for up to 3 days. If you haven’t finished it all, freezing is also an option!

Can I freeze this casserole for later use?
Yes, indeed! To freeze your casserole, place it in a well-sealed container or a heavy-duty freezer bag, removing as much air as possible. It can be frozen for up to 2 months. Simply label it with the date, and you’ll have a delicious meal ready to go whenever you need it!

What if my sauce is too thin?
If you find your sauce is a bit watery, don’t fret! To thicken it, let the mixture simmer on low heat longer, stirring frequently to prevent sticking. You can also add a teaspoon of cornstarch diluted in water, stirring it in until the sauce reaches your desired consistency. Remember, patience is key for that perfect creamy texture!

Are there any dietary considerations I should keep in mind?
Absolutely! This dish is low-carb and suitable for keto diets, but always check for allergies if serving to guests. If you’re using substitutes like heavy cream, opt for lactose-free options for those who are lactose intolerant. When enjoying leftovers, ensure they are reheated to an internal temperature of 165°F (75°C) for safety.

How can I prevent the spinach from being soggy?
Very! To avoid soggy spinach, make sure to use fresh baby spinach and not frozen unless it’s well-drained.
