How to Make Chicken Spinach and Mushroom Low Carb Oven Dish

Let’s get cooking! The beauty of this dish is how simple and seamless the process is. You’ll prep most of it in one skillet, then pop it into the oven to finish. Less fuss, more flavor.

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil or cooking spray.

2. Heat the olive oil in a large skillet over medium-high heat.

3. Season the chicken breasts with salt and pepper. Add them to the hot skillet and sear for 2–3 minutes per side, just until golden. They don’t need to be fully cooked—just a nice golden crust. Remove from the pan and set aside.

4. In the same skillet, sauté the garlic and mushrooms for 3–4 minutes, until the mushrooms soften and release their juices.

5. Add the chopped spinach, stirring until it wilts—this only takes a minute or two. Once done, remove the skillet from heat.

6. In a medium bowl, combine the heavy cream, mozzarella, Parmesan, thyme, and paprika. Stir until it forms a creamy, cheesy sauce.

7. Fold in the sautéed spinach and mushrooms to create the final creamy vegetable mixture.

8. Place the seared chicken breasts into the prepared baking dish. Pour the creamy mixture evenly over the top, making sure each piece is coated.

9. Bake uncovered for 25–30 minutes, or until the chicken is cooked through (internal temp should be 165°F/74°C) and the top is bubbly and golden.

10. Let it sit for a couple of minutes after removing from the oven. Then garnish with fresh chopped parsley and serve warm.

It smells so good, it’ll be hard to wait—but trust me, the short rest makes it even better.

Dairy-Free Option

Avoiding dairy? No problem! Swap the heavy cream for unsweetened coconut cream, and use your favorite dairy-free shredded cheese. The result is still creamy and satisfying—with a subtle coconut twist that actually pairs really well with the garlic and mushrooms.

Add More Veggies

Want to sneak in more greens or boost the bulk? Toss in sliced bell peppers, zucchini rounds, or diced onions when sautéing. These add natural sweetness, crunch, and extra color to the dish.

Use Chicken Thighs

Prefer dark meat? Go for boneless, skinless chicken thighs instead of breasts. They’re more tender and flavorful, and they hold up beautifully in the oven.

Gluten-Free Friendly

The dish is naturally gluten-free! Just be sure to double-check your cheese and seasoning blends to ensure there are no hidden gluten-containing additives.
