Ingredients You’ll Need
Every ingredient in this casserole plays a key role, from the juicy chicken to the creamy cheeses and fresh veggies, creating a harmonious blend of flavors and textures that come together effortlessly. Here’s what you’ll want to gather before getting started:
- 2 tbsp olive oil: Adds a smooth, fruity base for sautéing and helps everything cook evenly.
- 1 lb boneless, skinless chicken breasts (cut into bite-sized pieces): Lean protein that soaks up the seasonings beautifully.
- 2 cups fresh spinach (roughly chopped): Brings a fresh pop of green and subtle earthiness while keeping it low carb.
- 8 oz mushrooms (sliced): Adds meaty texture and umami depth to the casserole.
- 3 cloves garlic (minced): Infuses the dish with aromatic warmth and richness.
- 1/2 cup chopped onion: Provides mild sweetness and balances the savory flavors.
- 1/2 tsp salt: Essential to bring out all the flavors in the ingredients.
- 1/4 tsp black pepper: Adds gentle heat and complexity.
- 1 tsp Italian seasoning: A fragrant mix that perfectly complements chicken and mushrooms.
- 1/2 cup heavy cream: Delivers a luscious, velvety texture to the sauce.
- 4 oz cream cheese (softened): Adds tanginess and creaminess that marry the flavors beautifully.
- 1 cup shredded mozzarella cheese: Melts into a gooey, golden topping everyone will love.
- 1/2 cup grated Parmesan cheese: Offers a sharp, nutty finish that elevates the entire dish.
How to Make Chicken Spinach and Mushroom Low Carb Casserole Delight Recipe
Step 1: Cook the Chicken
Start by heating olive oil in a skillet over medium heat. Toss in the chicken pieces, seasoning them with salt, black pepper, and Italian seasoning as they sizzle. Cook until the chicken is no longer pink and is tender—about 6 to 8 minutes. Once done, remove the chicken and set it aside. This step creates a flavorful base, so take your time to develop a nice sear on the chicken for extra depth.
Step 2: Sauté the Vegetables
In the same skillet you just used, add the chopped onion and sliced mushrooms. Let them cook gently for 4 to 5 minutes until they soften and release their natural juices. Then, stir in the minced garlic and cook everything for an additional minute until fragrant. This layering of flavors is essential and fills your kitchen with an irresistible aroma.
Step 3: Add Spinach and Creamy Mixture
Next, stir in the chopped spinach and cook until it wilts, bringing a lovely green vibrance to the pan. Lower the heat, then add the softened cream cheese along with the heavy cream. Stir carefully until the sauce is silky smooth, cloaking the veggies in a rich, decadent sauce that ties everything together.
Step 4: Combine Chicken and Transfer to Baking Dish
Return the cooked chicken pieces to the skillet, stirring them into the creamy mixture so every bite is infused with flavor. Once combined, transfer the entire mixture into a greased 9×13-inch baking dish, spreading it out evenly to prepare for the final baking stage.
Step 5: Add Cheese Toppings and Bake
Sprinkle shredded mozzarella and grated Parmesan evenly over the top, creating a cheesy blanket that will bake into a golden, bubbly crust. Bake the casserole uncovered at 375°F for 20 to 25 minutes. You’ll know it’s ready when the cheese is melted and lightly browned, and the casserole is bubbly around the edges.
Step 6: Let it Rest and Serve
Allow the casserole to rest for 5 minutes out of the oven. This resting time helps the dish set, making it easier to serve and giving flavors a chance to meld beautifully.
How to Serve Chicken Spinach and Mushroom Low Carb Casserole Delight Recipe
Garnishes
A sprinkle of freshly chopped parsley or basil brings a fresh burst of color and herbal brightness that complements the creamy casserole perfectly. A light drizzle of extra virgin olive oil or a pinch of red pepper flakes can also enhance the dish’s flavor profile.
Side Dishes
This casserole is rich and satisfying on its own, but pairing it with a crisp mixed green salad or steamed low-carb veggies keeps the meal balanced and vibrant. Cauliflower rice or zucchini noodles are adorable low-carb companions to soak up any extra sauce.
Creative Ways to Present
Serve this casserole in individual ramekins for a cozy, personalized touch or pile it into a family-style dish right from the oven for casual sharing. For a fun twist, top individual servings with a fried egg or sliced avocado to add texture and creaminess.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftovers into airtight containers to keep them fresh in the fridge for up to 3 days. The flavors often deepen after resting, making your next meal even tastier.
Freezing
If you want to save the Chicken Spinach and Mushroom Low Carb Casserole Delight Recipe for a later date, it freezes wonderfully. Wrap it tightly and freeze for up to 2 months. Make sure to thaw overnight in the fridge before reheating for the best texture.
Reheating
Reheat individual portions in the microwave or the whole casserole in the oven at 350°F until warmed through and bubbly again. To keep the top from drying out, cover it loosely with foil during reheating.
FAQs
Can I use other types of cheese?
Absolutely! While mozzarella and Parmesan are classic in this dish, feel free to experiment with cheddar, Gruyère, or even a bit of feta to change up the flavor and richness.
Is this recipe keto-friendly?
Yes, this casserole fits perfectly into a keto lifestyle thanks to its low-carb ingredients and high fat content from cream and cheese.
Can I substitute the spinach with other greens?
Definitely! Kale, Swiss chard, or collard greens work beautifully as alternatives and offer their own unique flavors and nutrients.
What if I want to add some heat to the recipe?
Adding red pepper flakes while cooking the chicken or sprinkling some cayenne in the creamy sauce is a great way to turn up the heat without overpowering the dish.
Can I make this casserole dairy-free?
You can try swapping the heavy cream and cheeses for dairy-free versions like coconut cream and vegan cheese, but the texture and flavor will be different. Using those alternatives requires careful adjustments.
