Chicken Spinach and Mushroom Low Carb Oven Dish is a warm, comforting meal that’s full of flavor and perfect for those who want something satisfying without the heaviness of high-carb sides. This dish brings together tender baked chicken, earthy mushrooms, fresh spinach, and a creamy sauce made with green onion cream cheese. The mozzarella topping melts into a golden, bubbly layer, making every bite rich and delicious.
It’s an excellent choice for a weeknight dinner because it’s simple to prepare yet feels indulgent. The low-carb nature of the recipe means it can fit into a variety of eating plans, from keto to gluten-free lifestyles, but it’s also appealing to anyone who loves a creamy baked chicken dish.
The spinach adds freshness and a pop of color, while mushrooms bring an earthy depth of flavor. The green onion cream cheese gives the sauce a savory tang, balanced by the richness of olive oil and the lightness of chicken broth. Baking everything together allows the flavors to blend beautifully, and the final layer of melted mozzarella gives the dish that irresistible oven-baked finish.
Ingredients you will need
1 small bag fresh baby spinach
1 dash pepper
1 dash herb and garlic seasoning
8 ounces shredded mozzarella cheese
6 thin sliced chicken breasts
1 container green onion cream cheese
1/4 cup olive oil
1/2 cup chicken broth
1 large package sliced mushrooms
Step 1: Preparing the chicken and vegetables
Preheat your oven to 375°F (190°C). Take out a 9×13-inch baking dish and lay the chicken breasts in a single layer. Using thin sliced chicken ensures even cooking and allows the flavors to penetrate more easily.
On top of the chicken, add the fresh spinach, spreading it evenly so that every bite will have a bit of greens. Scatter the sliced mushrooms over the spinach layer. Sprinkle the pepper and herb and garlic seasoning over everything to start building flavor from the base up.
Step 2: Making the creamy sauce
In a small bowl, soften the green onion cream cheese so it’s easier to work with. You can leave it at room temperature for a few minutes or warm it briefly in the microwave. Whisk in the olive oil and chicken broth until the mixture is smooth and pourable. This will be the creamy sauce that ties the whole dish together.
Pour the cream cheese mixture evenly over the chicken, spinach, and mushrooms. It doesn’t need to completely cover every bit because as it bakes, the sauce will spread and mingle with the natural juices from the chicken and vegetables.
Step 3: Baking the dish
Lay a piece of aluminum foil over the top of the dish, but do not seal it tightly. This allows the chicken to steam slightly while still letting some moisture escape, preventing the dish from becoming watery.
Bake in the preheated oven for 20 minutes. After that, remove the foil and continue baking uncovered for another 20 to 25 minutes. This uncovered time helps reduce excess liquid and allows the top to start taking on color.
Step 4: Adding the mozzarella topping
Once the chicken is nearly done, sprinkle the shredded mozzarella cheese evenly over the top. Return the dish to the oven and bake uncovered for about 10 minutes, or until the cheese is melted, bubbly, and just starting to turn golden brown.
Step 5: Resting and serving
Remove the dish from the oven and let it cool for about 10 minutes before serving. This resting time allows the sauce to thicken slightly and makes serving cleaner.
Serving suggestions
This Chicken Spinach and Mushroom Low Carb Oven Dish can stand on its own as a complete meal thanks to the balance of protein, vegetables, and creamy sauce. However, you can also serve it with a side salad for extra freshness, or alongside roasted vegetables for more variety. If carbs aren’t a concern, it pairs beautifully with crusty bread or a small portion of rice to soak up the sauce.
Tips for best results
Choose fresh baby spinach rather than frozen for the best texture. Frozen spinach can be used in a pinch, but be sure to thaw and squeeze out excess water before adding it to the dish.
If you prefer a sharper cheese flavor, you can replace part of the mozzarella with provolone or fontina.
For extra flavor, lightly sauté the mushrooms before adding them to the dish. This will deepen their flavor and remove some of their moisture before baking.
The recipe can be doubled for larger gatherings—just use a larger baking pan or two separate pans to ensure even cooking.
Storage and reheating
Leftovers can be stored in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave, adding a small splash of chicken broth if needed to refresh the sauce. This dish can also be frozen, although the texture of the spinach may soften further after thawing.
