* 2 tablespoons olive oil
* 1.5 pounds boneless, skinless chicken breasts, cut into 1-inch cubes
* 1 teaspoon garlic powder
* 1/2 teaspoon onion powder
* 1/2 teaspoon dried Italian seasoning
* Salt and freshly ground black pepper, to taste
* 1 tablespoon unsalted butter
* 8 ounces cremini mushrooms, sliced
* 5 ounces fresh spinach
* 1/2 cup chicken broth (low sodium preferred)
* 8 ounces cream cheese, softened
* 1/2 cup heavy cream
* 1/2 cup grated Parmesan cheese, plus extra for topping
* 1/4 cup shredded mozzarella cheese, plus extra for topping
* 2 tablespoons fresh parsley, chopped, for garnish
Substitutions & Variations
This Chicken Spinach & Mushroom Low Carb Oven Dish is wonderfully adaptable, allowing you to tailor it to your preferences or what you have on hand. Don’t be afraid to get creative! For instance, if you don’t have chicken breasts, boneless, skinless chicken thighs work beautifully.
They tend to be even more flavorful and forgiving, though they might require an extra minute or two to cook through. Simply adjust the cooking time slightly when making this low carb chicken oven dish.
Furthermore, while cremini mushrooms offer a lovely earthy flavor, white button mushrooms or even a mix of wild mushrooms would be fantastic in this keto chicken spinach mushroom bake. Experiment with different mushroom varieties to discover your favorite! If fresh spinach isn’t available, you can use frozen spinach.
Just be sure to thaw it completely and squeeze out as much excess water as possible before adding it to the pan. This step is crucial to prevent your healthy chicken casserole from becoming watery.
Regarding the cheeses, feel free to play around with them. While Parmesan and mozzarella provide a classic flavor and gooey texture, shredded cheddar, Gruyere, or even a Monterey Jack would also melt beautifully into this oven-baked chicken and veggies dish.
For a dairy-free version, you could try using a cashew cream base instead of cream cheese and heavy cream, along with your favorite dairy-free shredded cheeses. However, please note that this will alter the flavor and texture significantly from the original chicken spinach mushroom bake.
Moreover, you can boost the vegetable content in this one-pan low carb chicken recipe. Consider adding diced bell peppers, chopped zucchini, or even a handful of frozen peas (if you don’t mind a few extra carbs) alongside the spinach and mushrooms.
A pinch of red pepper flakes would also add a delightful subtle heat to this easy keto chicken meal, elevating the flavor profile. This allows for endless variations, always resulting in a delicious and satisfying oven-baked low carb chicken meal.
Step-by-Step Instructions
Creating this delicious Chicken Spinach & Mushroom Low Carb Oven Dish is a straightforward process. Follow these steps for a perfect, comforting meal every time.
First, preheat your oven to 375°F (190°C). Then, in a large bowl, toss the cubed chicken breasts with olive oil, garlic powder, onion powder, Italian seasoning, salt, and pepper. Make sure every piece of chicken is well coated.
Next, heat the butter in a large oven-safe skillet (like a cast iron skillet) or a Dutch oven over medium-high heat. Add the seasoned chicken to the hot skillet in a single layer. Sear the chicken for 3-4 minutes per side until lightly browned.
It doesn’t need to be cooked through at this stage; we just want to develop some color and flavor. Remove the chicken from the skillet and set it aside.
Now, add the sliced mushrooms to the same skillet, adding a touch more olive oil if needed. Sauté the mushrooms for 5-7 minutes until they are softened and have released their liquid. Then, add the fresh spinach to the skillet, stirring until it wilts completely, which usually takes just 2-3 minutes. This vibrant addition makes our low carb chicken oven dish visually appealing and nutritious.
Pour in the chicken broth, scraping up any browned bits from the bottom of the skillet – these bits add amazing flavor to your creamy sauce. Reduce the heat to low, then add the softened cream cheese and heavy cream. Stir continuously until the cream cheese is fully melted and you have a smooth, creamy sauce.
Stir in the Parmesan and mozzarella cheeses until they are melted and well combined. Taste the sauce and adjust seasonings (salt, pepper) as needed for your perfect chicken spinach mushroom bake.
Finally, return the seared chicken to the skillet, gently stirring to coat it evenly with the creamy sauce. Top the entire dish with a little extra Parmesan and mozzarella cheese for a beautiful golden crust. Transfer the skillet to the preheated oven.
Bake for 18-22 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C) and the cheese is bubbly and golden. This transforms the dish into a truly delicious and healthy chicken casserole. Remove from the oven, garnish with fresh chopped parsley, and let it rest for a few minutes before serving. Enjoy your homemade Chicken Spinach & Mushroom Low Carb Oven Dish!
Pro Tips for Success
Achieving perfection with this Chicken Spinach & Mushroom Low Carb Oven Dish is easier than you think, especially with a few insider tricks. First, for truly tender chicken, avoid overcooking it during the initial searing stage. We’re just looking for a nice golden-brown crust, as it will finish cooking in the oven within the creamy sauce. This two-stage cooking method ensures moist, flavorful chicken every time in your low carb chicken oven dish.
Secondly, always use softened cream cheese. Taking it out of the fridge about 30 minutes before you start cooking will make it much easier to melt into a smooth sauce, preventing lumps. This is key for the luxurious texture of your keto chicken spinach mushroom bake.
Another crucial tip: when sautéing the mushrooms, avoid overcrowding the pan. Cook them in batches if necessary. Overcrowding steams the mushrooms rather than browning them, which means you miss out on that rich, umami flavor. Browning them properly adds depth to your healthy chicken casserole.
Furthermore, don’t skimp on seasoning the chicken initially. A well-seasoned chicken breast lays the foundation for a truly delicious oven-baked chicken and veggies dish. Taste the sauce before adding the chicken back in.
This gives you a chance to adjust salt, pepper, or even add a pinch more garlic powder or Italian seasoning to suit your palate. Remember, building layers of flavor is what makes a dish truly special.
Lastly, for a beautifully golden and bubbly top, consider placing the skillet under the broiler for the last 1-2 minutes of cooking. Keep a very close eye on it to prevent burning, but this step will give your chicken spinach mushroom bake that irresistible golden crust we all love. This small effort transforms your one-pan low carb chicken into a showstopper. Enjoy this incredible Chicken Spinach & Mushroom Low Carb Oven Dish!

Storage & Reheating Tips
One of the many benefits of this amazing Chicken Spinach & Mushroom Low Carb Oven Dish is how well it stores and reheats. This makes it a fantastic option for meal prep or enjoying leftovers throughout the week. To store, first allow the dish to cool completely to room temperature.
This is an important step to prevent bacterial growth and maintain food quality. Once cooled, transfer the leftover low carb chicken oven dish to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days.
When you’re ready to enjoy your healthy chicken casserole again, reheating is simple. For the best results, reheat individual portions in the microwave. Place a portion in a microwave-safe dish, cover it loosely, and heat on medium power for 2-3 minutes, stirring halfway through, until thoroughly heated.
If you prefer using the oven, place leftovers in an oven-safe dish, cover it with foil, and bake at 300°F (150°C) for about 15-20 minutes, or until warmed through. Adding a tablespoon of extra chicken broth or heavy cream before reheating can help refresh the sauce and prevent it from drying out. This ensures your oven-baked chicken and veggies dish retains its creamy texture.
You can also freeze this Chicken Spinach & Mushroom Low Carb Oven Dish for longer storage. Transfer cooled leftovers to a freezer-safe container, ensuring it’s tightly sealed. It will last in the freezer for up to 2-3 months.
When ready to eat, thaw the dish overnight in the refrigerator, then reheat using one of the methods mentioned above. Freezing might slightly alter the texture of the sauce and mushrooms, but it will still be a delicious and convenient meal. Enjoy the versatility of this easy keto chicken meal!
What to Serve With This Recipe
This Chicken Spinach & Mushroom Low Carb Oven Dish is so rich and satisfying, it truly stands on its own. However, pairing it with the right side dishes can elevate the meal, adding complementary textures and flavors, all while keeping it low carb!
For a simple and elegant accompaniment, consider serving a fresh green salad with a light vinaigrette. The crispness of the lettuce and the tang of the dressing provide a perfect contrast to the creamy richness of the chicken spinach mushroom bake. It’s a classic pairing that never disappoints.
