Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• Boneless, skinless chicken breasts

• Fresh spinach leaves

• Mushrooms, sliced (I like using cremini or white button)

• Garlic cloves, minced

• Onion, finely chopped

• Cream cheese

• Heavy cream

• Shredded mozzarella or provolone

• Grated Parmesan cheese

• Olive oil or butter

• Salt and black pepper

• Paprika (optional, for color)

• Fresh parsley (optional, for garnish)

Directions

1. I preheat the oven to 375°F (190°C) and lightly grease a baking dish.

2. I season the chicken breasts with salt, pepper, and a sprinkle of paprika, then sear them in a skillet with olive oil for 2–3 minutes per side, just until golden (they’ll finish cooking in the oven).

3. In the same skillet, I sauté the onions and garlic until fragrant, then add the mushrooms and cook until they release their moisture and start to brown.

4. I toss in the spinach and cook it just until wilted.

5. I stir in the cream cheese and heavy cream, mixing until it forms a smooth, creamy sauce. I add some Parmesan for extra flavor.

6. I place the seared chicken breasts in the baking dish, spoon the creamy mushroom-spinach mixture over the top, and sprinkle everything with shredded mozzarella.

7. I bake uncovered for about 20–25 minutes, or until the chicken is cooked through and the top is golden and bubbly.

8. I let it rest a few minutes before garnishing with parsley and serving.

Servings and timing

This recipe serves 4 people and takes about 40 minutes total—15 minutes for prep and 25 minutes in the oven. It’s perfect for a weeknight dinner or even meal prep for a few days ahead.

Variations

• I sometimes add chopped sun-dried tomatoes for a tangy twist.

• For extra protein, I use chicken thighs instead of breasts—they stay super juicy.

• I like to switch up the cheese by using Gruyère or fontina for a nuttier flavor.

• When I want more vegetables, I stir in some steamed broccoli or cauliflower before baking.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. When I reheat it, I use the oven or a skillet over low heat to preserve the texture of the sauce and chicken. The microwave works too, but I cover it to prevent drying out. This dish doesn’t freeze well due to the dairy, but it’s so good, I rarely have leftovers anyway.

FAQs

Can I use frozen spinach instead of fresh?

Yes, I just make sure to thaw and squeeze out all excess water before adding it to the skillet. This keeps the sauce from getting watery.

How do I know the chicken is cooked through?

I check that the internal temperature reaches 165°F (74°C) with a meat thermometer. The juices should run clear and the meat should be white inside.

Can I make this dish ahead of time?

Absolutely. I assemble the dish up to the baking step and store it covered in the fridge for up to 24 hours. Then I bake it when I’m ready to serve.

What mushrooms work best?

I prefer cremini or white button mushrooms because they’re easy to find and have great flavor, but baby bellas or even chopped portobellos work well too.

Is this recipe keto-friendly?

Yes, it’s low in carbs and high in fat and protein, making it a great option for a keto or low-carb lifestyle.

Conclusion

This Chicken Spinach and Mushroom Low Carb Oven Dish is creamy, comforting, and full of flavor—without all the carbs. I love how easy it is to prepare and how satisfying each bite is.
