How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Bake Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 375°F (190°C) so it’s ready to go when you finish the stovetop steps. Cutting your chicken breasts into bite-sized pieces ensures they cook evenly and soak up all the delicious flavors from the veggies and cream.
Step 2: Sauté the Aromatics
Heat olive oil in a large skillet over medium heat and add finely chopped onion and minced garlic. Cooking them until translucent and fragrant—about 3 to 4 minutes—creates a savory flavor foundation that will carry through the entire dish.
Step 3: Cook the Mushrooms
Toss in the sliced mushrooms and let them soften, releasing their earthy aroma and juices. Stir occasionally and keep cooking for 5 to 6 minutes until they’re lightly browned, adding wonderful texture and richness.
Step 4: Wilt the Spinach
Stir in the chopped spinach and cook just until wilted, roughly 2 minutes. This quick step preserves the vibrant green color and fresh flavor, making the dish look as good as it tastes.
Step 5: Combine Chicken and Veggies
Remove the skillet from heat, then transfer the vegetable mixture into a large mixing bowl. Add the chicken pieces and season everything with dried oregano, thyme, salt, and pepper. This combination of herbs adds a fragrant Mediterranean vibe that’s so satisfying.
Step 6: Add Cream and Cheese
Pour in the heavy cream and stir in half of the shredded mozzarella cheese. Gently fold the ingredients together to coat every bite-sized chicken piece, creating a rich, creamy base that bakes into a luscious casserole.
Step 7: Assemble and Bake
Grease a baking dish and spread the mixture evenly inside. Sprinkle the remaining mozzarella and grated Parmesan cheese on top, ensuring a golden, bubbly cheese crust forms in the oven. Bake uncovered for 25 to 30 minutes, or until the chicken is thoroughly cooked and the cheese has melted to perfection.
Step 8: Let It Rest
After baking, give the dish a few minutes to cool slightly. This resting time helps all the flavors settle and makes serving easier without losing any of that delicious juiciness.
