How to Make Chicken Spinach Mushroom Low Carb Oven Dish Recipe
Step 1: Prep and Preheat
First things first, set your oven to 375°F (190°C) so it’s ready by the time you finish prepping. This simple step ensures a smooth cooking flow and perfectly baked results.
Step 2: Sauté Mushrooms
Heat the olive oil in a large skillet over medium heat and add your sliced mushrooms. Let them cook for 5 to 7 minutes until they soften and take on a beautiful golden-brown color. This develops a deep, rich flavor that’s essential for the dish’s savory notes.
Step 3: Wilt the Spinach
Once the mushrooms are just right, toss in the chopped spinach and sauté for an additional 2 to 3 minutes until it wilts down nicely. Don’t overcook; you want it tender but still vibrant. Once done, take the skillet off the heat and set aside this delicious veggie mix.
Step 4: Season the Chicken
In a mixing bowl, combine the chicken pieces with garlic powder, onion powder, dried oregano, paprika, salt, and pepper. Mix thoroughly so every bite of chicken is packed with flavor. This seasoning blend is what makes this recipe so crave-worthy and satisfying.
Step 5: Arrange Layers in Baking Dish
Spread the seasoned chicken evenly across your baking dish to ensure even cooking. Next, layer the sautéed spinach and mushrooms right on top, building those wonderful flavors upward.
Step 6: Add the Cheeses and Optional Heat
Now comes the best part: sprinkle the shredded mozzarella cheese evenly over the veggies, then follow with a generous dusting of grated Parmesan. If you’re feeling adventurous, add red pepper flakes for a subtle but lively heat boost.
Step 7: Bake Covered
Cover the baking dish with foil and slide it into the preheated oven. Let it bake for 25 to 30 minutes, until the chicken is cooked through—the internal temperature should hit 165°F (74°C), ensuring juicy and safe-to-eat meat.
Step 8: Brown the Cheese
Remove the foil for the last 5 to 10 minutes of baking to allow the cheese to bubble up and turn a gorgeous golden brown. This step adds that glorious crispy texture and irresistible aroma.
Step 9: Rest and Serve
Once out of the oven, let the dish cool for a few minutes so the flavors settle and serving is easy. Then dig in and enjoy the wholesome, comforting magic of this low carb oven dish!
