How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe
Step 1: Sauté the Aromatics
Start by preheating your oven to 375°F (190°C) so it’s ready when your mixture is prepared. Heat the olive oil in a large skillet over medium heat, then add the finely chopped onion and minced garlic. Sauté them together for about 3-4 minutes until they become translucent and release that incredible fragrant aroma that sets the stage for the entire dish.
Step 2: Cook the Mushrooms
Next, toss the sliced mushrooms into the skillet with the onions and garlic. Cook for 5-6 minutes until the mushrooms soften and develop a beautiful golden-brown color. This step is key because it enhances their earthy flavor, which is a cornerstone to this comforting low-carb dish.
Step 3: Add the Spinach
Now, stir the chopped spinach into the skillet and cook it down for about 2 minutes until it wilts down. This wilting will concentrate the flavor while maintaining that lovely green pop. Once done, remove the skillet from the heat, allowing the mixture to cool slightly before combining with the chicken.
Step 4: Combine Chicken and Vegetables
In a large mixing bowl, add your bite-sized chicken pieces. Pour in the sautéed spinach and mushroom mixture and sprinkle in the dried oregano, thyme, salt, and pepper. Give everything a gentle toss so the herbs and seasoning coat the chicken and vegetables evenly, distributing the flavors beautifully throughout.
Step 5: Add Cream and Cheese
Pour in the half cup of heavy cream along with half of the shredded mozzarella cheese. Stir gently until the cream and cheese meld with the chicken and vegetables, creating a rich, velvety coating that promises every bite will be comforting and full of flavor.
Step 6: Bake to Perfection
Transfer your mixture into a greased baking dish, spreading it out evenly. Sprinkle the remaining mozzarella cheese and the Parmesan cheese evenly over the top; this layering is important as these cheeses bake into a golden, bubbly crust that makes this dish truly special. Place it in the oven and bake uncovered for 25-30 minutes, until the chicken is fully cooked and the cheese is irresistible golden brown.
How to Serve Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe

Garnishes
A sprinkle of fresh parsley or basil on top right before serving adds a fresh herbaceous brightness that perfectly contrasts the rich, creamy flavors of the dish. A light drizzle of extra virgin olive oil can also elevate the richness and add a lovely sheen.
Side Dishes
Since the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe is low in carbs but full of hearty protein and vegetables, pairing it with a fresh salad or steamed green veggies like asparagus or broccoli works beautifully. Cauliflower rice is another excellent side if you want to keep it low-carb and filling.
Creative Ways to Present
For a fun twist, serve the dish in individual ramekins or mini cast iron skillets to add a rustic charm. You can also scoop the warm, cheesy mixture into bell pepper halves for an eye-catching presentation that doubles as extra veggies on the plate.
Make Ahead and Storage
Storing Leftovers
This Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe keeps well in the fridge for up to 3 days when stored in an airtight container. The flavors often deepen overnight, making leftovers just as delightful as fresh.
Freezing
You can freeze this dish if you want to prep meals ahead of time. Make sure to cool it completely, then transfer to freezer-safe containers. It will keep well for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F for about 15-20 minutes until warmed through to preserve the crispy cheese topping. Alternatively, a quick microwave session covered loosely with a paper towel will do, though the texture of the cheese may soften.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs add a bit more juiciness and richness which works wonderfully with the creamy sauce in this recipe. Just remember to cut them into bite-sized pieces as with the breasts.
Is this dish suitable for keto diets?
Yes, this Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe fits perfectly within a keto diet thanks to its low-carb ingredients and high-fat content from the cheeses and cream.
Can I substitute the fresh spinach with frozen spinach?
You can, but make sure to thaw and squeeze out excess water to prevent the dish from becoming too watery. Fresh spinach provides the best texture and flavor, but frozen works in a pinch.
What type of mushrooms are best for this recipe?
Common white button mushrooms or cremini mushrooms are ideal because they have a mild yet earthy flavor that complements the creamy sauce without overpowering it.
Can I add other vegetables to the dish?
Definitely! Feel free to incorporate other low-carb favorites like bell peppers, zucchini, or even some roasted cherry tomatoes to add extra layers of flavor and nutrition.
