Ingredients

2 lbs boneless, skinless chicken breasts or thighs, cut into 1-inch cubes
1 tbsp olive oil
1 medium yellow onion, chopped
2 cloves garlic, minced
8 oz cremini or baby bella mushrooms, sliced
5 oz fresh spinach
8 oz cream cheese, softened
1/2 cup heavy cream
1/2 cup chicken broth (low sodium)
1 cup shredded mozzarella cheese, divided
1/2 cup grated Parmesan cheese
1 tsp dried Italian seasoning
1/2 tsp salt, or to taste
1/4 tsp black pepper, or to taste
Optional: 1/4 tsp red pepper flakes for a kick
Optional: 2 tbsp fresh parsley, chopped, for garnish

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
In a large skillet or oven-safe pan, heat the olive oil over medium-high heat. Add the cubed chicken and cook until browned on all sides, about 5-7 minutes. The chicken does not need to be cooked through at this stage. Remove the chicken from the skillet and set aside.
In the same skillet, add the chopped onion and cook until softened, about 3-4 minutes. Add the minced garlic and sliced mushrooms. Sauté for another 5-7 minutes, until the mushrooms are tender and have released their liquid.
Add the fresh spinach to the skillet. Cook, stirring occasionally, until the spinach has wilted completely, about 2-3 minutes.
Reduce the heat to low. Add the softened cream cheese, heavy cream, chicken broth, Italian seasoning, salt, and pepper to the skillet. Stir constantly until the cream cheese is fully melted and the sauce is smooth and creamy. If using, add red pepper flakes.
Stir in half of the shredded mozzarella cheese (1/2 cup) and all of the grated Parmesan cheese into the sauce until well combined and melted.
Return the browned chicken to the skillet with the creamy sauce and vegetables. Stir everything together gently to ensure the chicken is fully coated.
Pour the entire mixture into the prepared 9×13-inch baking dish, spreading it evenly.
Sprinkle the remaining 1/2 cup of shredded mozzarella cheese over the top of the dish.
Bake for 20-25 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C), the sauce is bubbly, and the cheese on top is melted and lightly golden.
Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh chopped parsley, if desired.

Cooking Tips and Variations

To ensure your Chicken Spinach and Mushroom Low Carb Oven Dish is always a resounding success, here are some expert tips and creative variations to keep things exciting:

Pre-Cooking Chicken for Flavor: While the recipe calls for browning the chicken, fully cooking it before adding it to the sauce can enhance its flavor and prevent it from drying out during the bake. You could also grill or air fry the chicken cubes separately for a slightly different texture before combining.
Mushroom Prep: Always clean your mushrooms by gently wiping them with a damp cloth or a mushroom brush instead of rinsing them under water. Mushrooms are like sponges and will absorb water, leading to a less flavorful, soggy texture when cooked.
Creamy Sauce Thickening: If you prefer a thicker sauce, you can add 1/4 teaspoon of xanthan gum to the cream cheese mixture while whisking. Add it slowly and whisk vigorously to avoid clumps. Alternatively, allowing the casserole to rest for 10-15 minutes after baking will naturally thicken the sauce as it cools slightly.
Cheese Power: Feel free to experiment with other low-carb cheeses. Provolone, Gruyere, or even a sharp cheddar can add different dimensions of flavor. A sprinkle of crumbled feta cheese on top could also provide a tangy contrast.
Vegetable Boost: This dish is incredibly flexible! Consider adding other low-carb vegetables like diced bell peppers, chopped asparagus, or even a handful of kale along with the spinach. Just be sure to sauté harder vegetables first to soften them.
Herb Garden: Don’t limit yourself to Italian seasoning. Fresh herbs like thyme, rosemary, or oregano can be excellent additions. Add them in moderation with the garlic and mushrooms to infuse their flavors.
Spice It Up: For those who love a bit of heat, increase the red pepper flakes or add a pinch of cayenne pepper to the sauce. A dash of hot sauce stirred in at the end can also provide a nice kick.
Make Ahead Magic: You can assemble the entire casserole (up to step 8) a day in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove it from the fridge 30 minutes prior to baking to allow it to come closer to room temperature, then bake as directed, possibly adding 5-10 minutes to the baking time.
Broth Alternatives: If you don’t have chicken broth, vegetable broth can be used as a substitute without significantly altering the flavor profile.
Browning the Top: For an extra golden and crispy cheese topping, you can place the dish under the broiler for 1-2 minutes at the very end of the baking time. Watch it closely to prevent burning!
Serving Suggestion: While delicious on its own, this dish pairs wonderfully with a simple side salad dressed with a vinaigrette, steamed green beans, or cauliflower rice for a complete low-carb meal.

Storage and Reheating

This Chicken Spinach and Mushroom Low Carb Oven Dish is excellent for meal prepping and makes for fantastic leftovers. Here’s how to store and reheat it properly:

Storage: Allow the casserole to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3-4 days.
Freezing: For longer storage, you can freeze individual portions or the entire casserole. Once cooled, place it in freezer-safe containers or wrap the baking dish tightly with plastic wrap and then aluminum foil. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
Reheating (Microwave): For individual servings, place a portion in a microwave-safe dish. Heat on medium power for 2-4 minutes, stirring halfway through, until heated through.
Reheating (Oven): For larger portions or a whole casserole, preheat your oven to 350°F (175°C). Cover the dish with aluminum foil to prevent drying out and bake for 20-30 minutes, or until heated through. If reheating from frozen, it may take 45-60 minutes. Remove the foil for the last 5-10 minutes if you want to crisp up the cheese topping.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Yes, you can absolutely use frozen spinach. Thaw 10-12 ounces of frozen spinach and squeeze out as much excess water as possible before adding it to the skillet. This step is crucial to prevent your casserole from becoming watery.

Is this dish suitable for those with dairy allergies?

Unfortunately, this recipe relies heavily on dairy products like cream cheese, heavy cream, and mozzarella. Substituting all of these with dairy-free alternatives might significantly alter the taste and texture. There are some excellent dairy-free cream cheeses and shredded cheeses available that you could try, but the results may vary.

How can I make this dish spicier?

To add more heat, you can increase the amount of red pepper flakes or add a pinch of cayenne pepper to the sauce. For a fresh kick, a finely diced jalapeño or serrano pepper could be sautéed with the onions and garlic. A drizzle of your favorite hot sauce over the top before serving also works wonders.
