Step‑by‑Step Instructions for Chicken Spinach Mushroom Low Carb Oven Dish
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This crucial step ensures that your Chicken Spinach Mushroom Low Carb Oven Dish cooks evenly, giving you that perfect golden-brown finish. While the oven heats up, you can gather your ingredients and prep the vegetables, which makes the process smooth and seamless.
Step 2: Sauté the Mushrooms
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 2 cups of sliced mushrooms and sauté for 5–7 minutes, stirring occasionally, until they become soft and golden brown. The aroma will fill your kitchen, signaling that your dish is coming to life! Once they are cooked, remove the skillet from heat and set it aside for later use.
Step 3: Add the Spinach
Next, incorporate 2 cups of chopped fresh spinach into the skillet with the mushrooms. Return the skillet to medium heat and sauté for an additional 2–3 minutes, or until the spinach is wilted and vibrantly green. This step adds a nutritious element to your Chicken Spinach Mushroom Low Carb Oven Dish, enhancing both flavor and color. Remove the skillet from the heat once done.
Step 4: Season the Chicken
In a mixing bowl, take 1 pound of bite-sized boneless, skinless chicken breasts. Season them generously with 1 teaspoon of garlic powder, 1 teaspoon of onion powder, 1 teaspoon of dried oregano, 1 teaspoon of paprika, along with salt and pepper to taste. Mix thoroughly to ensure each piece of chicken is evenly coated with the spices, creating a delicious flavor base.
Step 5: Layer the Ingredients
In a large baking dish, spread the seasoned chicken pieces in an even layer. This ensures all the chicken cooks uniformly. Then, pour the sautéed spinach and mushrooms over the chicken to create a beautiful layered effect. The colors and textures will make your Chicken Spinach Mushroom Low Carb Oven Dish truly inviting.
Step 6: Add the Cheesy Toppings
Generously sprinkle 1 cup of shredded mozzarella cheese over the top, followed by ½ cup of grated Parmesan cheese. The combination of these cheeses will result in a delicious, gooey topping. For an extra kick, you can sprinkle in ¼ teaspoon of red pepper flakes if you like a bit of heat in your dish, adding another layer of flavor.
Step 7: Bake the Dish
Cover the baking dish with aluminum foil and place it in your preheated oven. Bake for 25–30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C). Removing the foil keeps the moisture in, ensuring your Chicken Spinach Mushroom Low Carb Oven Dish remains juicy and tender throughout the cooking process.
Step 8: Finish with a Crisp
After the chicken is cooked, remove the foil and continue baking for an additional 5–10 minutes. This step allows the cheese to bubble and turn a beautiful golden brown, creating a crispy, enticing top layer. The melty cheese will be the perfect finishing touch to your flavorful dish.
Step 9: Cool Before Serving
Once baked to perfection, carefully take the dish out of the oven and let it cool for a few minutes. This resting time allows the flavors to meld together and makes serving easier. Your Chicken Spinach Mushroom Low Carb Oven Dish is now ready to delight family and friends at your dinner table!
