Ingredients You’ll Need
The ingredients for this recipe are wonderfully straightforward but each plays a vital role in building layers of flavor, creamy texture, and vibrant color. From the juicy chicken that forms the base to the fresh spinach and earthy mushrooms that bring depth, every item in this list is essential.
- 4 boneless, skinless chicken breasts: The lean protein foundation that cooks up juicy and tender.
- 2 tbsp olive oil: For creating that golden sear on the chicken and sautéing veggies.
- 2 cups fresh spinach, chopped: Adds a fresh, slightly sweet earthiness and beautiful green color.
- 1 cup mushrooms, sliced: Brings an umami richness and meaty bite to the dish.
- 3 cloves garlic, minced: Infuses the sauce with aromatic warmth.
- 1/2 cup heavy cream: Creates a luxuriously creamy sauce that clings to every ingredient.
- 1/4 cup chicken broth (or vegetable broth): Adds moisture and subtle savory depth.
- 1/2 cup shredded mozzarella cheese: Melts beautifully for that gooey, cheesy topping.
- 1/4 cup grated Parmesan cheese: Offers a sharp, nutty contrast that enhances all the other flavors.
- Salt and pepper, to taste: Simple seasonings that bring everything to life.
- 1 tsp dried thyme or Italian seasoning: A fragrant herb blend that complements chicken and veggies perfectly.
- Fresh parsley, chopped (optional, for garnish): Adds a pop of fresh color and mild herbaceous brightness.
How to Make Chicken, Spinach, and Mushroom Low Carb Oven Dish Recipe
Step 1: Preheat Your Oven
Begin by heating your oven to 375°F (190°C). Preparing your baking dish by greasing it or lining it with parchment paper sets the stage for an easy cleanup and ensures your dish doesn’t stick while baking.
Step 2: Cook the Chicken
In a large skillet over medium heat, warm the olive oil. Season your chicken breasts with salt, pepper, and your choice of dried thyme or Italian seasoning. Sear the chicken for about 5 to 6 minutes per side until they reach a gorgeous golden brown and are cooked through. Set the cooked chicken aside to rest—this keeps the juices locked inside for maximum tenderness.
Step 3: Sauté Vegetables
Using the same skillet saves on washing up and lets the garlic and mushroom flavors build right where your chicken cooked. Add the minced garlic and sauté for just a minute to release its fragrance. Toss in the mushrooms, cooking them until they soften and give off their evoking earthiness—around 5 minutes. Finally, stir in the chopped spinach and cook until just wilted, which takes about 2 to 3 minutes. This combination is the heart of your creamy sauce.
Step 4: Create the Creamy Sauce
Pour in the heavy cream and chicken broth, stirring to combine all the delicious bits left in the pan. Bring the mixture to a gentle simmer, allowing it to thicken slightly over 3 to 4 minutes, creating a luscious sauce that clings completely to the chicken and veggies.
Step 5: Assemble and Bake
Place the cooked chicken breasts into the prepared baking dish. Pour the creamy spinach and mushroom sauce right over the chicken, spreading it evenly. Top everything with shredded mozzarella and grated Parmesan cheese. Pop the dish into your preheated oven and bake for 15 to 20 minutes until the cheese melts to bubbly, golden perfection and the sauce is heated through.
Step 6: Serve and Enjoy
Once baked, garnish with freshly chopped parsley for a vibrant finishing touch. Serve warm and revel in this comforting yet light meal.

Garnishes
Fresh parsley isn’t just for looks—it adds a bright herbal pop that cuts through the creamy richness beautifully. A sprinkle of extra Parmesan at the table can also elevate the savoriness for cheese lovers.
Side Dishes
While this dish stands beautifully on its own as a low carb feast, pairing it with a crunchy green salad or roasted vegetables brings additional texture and color to your plate. Cauliflower rice or zucchini noodles make excellent complementary low carb sides that soak up the creamy sauce perfectly.
Creative Ways to Present
Try plating individual portions in shallow bowls to showcase the luscious sauce and gooey cheese. Drizzle a little extra olive oil or a squeeze of fresh lemon juice over each plate for a subtle brightness that highlights the dish’s richness.
Make Ahead and Storage
Storing Leftovers
Leftover Chicken, Spinach, and Mushroom Low Carb Oven Dish Recipe keeps wonderfully in an airtight container in the refrigerator for up to three days. The flavors develop even more, making for an excellent next-day meal.
Freezing
This dish can be frozen for up to one month. It’s best to freeze before baking: assemble the dish, cover tightly, and freeze. When ready to enjoy, thaw overnight in the refrigerator before baking.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) until warmed through to help maintain the creamy texture and avoid drying out. Alternatively, microwave on medium power in short intervals, stirring midway.
FAQs
Can I use frozen spinach instead of fresh?
Yes, you can, but be sure to thaw and squeeze out excess moisture from the frozen spinach before adding it to prevent the sauce from becoming watery.
What if I don’t have heavy cream? Can I substitute it?
You can use full-fat coconut milk or half-and-half as alternatives, though the sauce might be slightly less rich but still delicious.
Is this dish suitable for meal prepping?
Absolutely! It holds up well in the fridge and reheats nicely, making it perfect for prepping lunches or dinners for the week.
Can I make this recipe dairy-free?
To keep it dairy-free, substitute the cheeses with dairy-free alternatives and swap heavy cream for coconut cream. Adjust seasoning accordingly for the best taste.
How can I add more protein to this dish?
Consider adding cooked bacon bits, diced ham, or even topping with a fried egg for an extra protein boost that complements the flavors.
