How to Make Chicken Spinach Mushroom Low Carb Oven Dish
Preheat and Prepare: Begin by preheating your oven to 375°F (190°C). While that’s warming up, season your chicken breasts generously with salt, pepper, thyme, oregano, and basil. Make sure to coat both sides well—this sets the stage for flavor from the inside out.
Sear the Chicken: Heat olive oil in a large oven-safe skillet over medium-high heat. Once the oil is shimmering, add in the seasoned chicken breasts. Sear each side for about 2-3 minutes until you achieve that beautiful golden-brown crust. The chicken should easily release from the pan when it’s time to flip. After searing, remove the chicken from the skillet and set aside while you prepare the veggies.
Sauté the Mushrooms: In the same skillet, melt butter over medium heat. Add the sliced mushrooms and minced garlic, allowing them to sauté for about 5-7 minutes. Don’t stir them right away; let the mushrooms sit undisturbed to achieve a nice browning. You’ll know they are ready when they are tender and fragrant, with a delightful golden color.
Add the Spinach: Now it’s time to bring in that vibrant green goodness! Toss the fresh spinach into the skillet with the sautéed mushrooms. Keep stirring for another 2-3 minutes until the spinach wilts completely—it’ll reduce significantly in volume but pack a nutritional punch.
Prepare the Creamy Sauce: In a mixing bowl, whisk together the softened cream cheese, heavy cream, freshly grated Parmesan cheese, and chicken broth until smooth. This dreamy mixture should be free of lumps and creamy. Depending on your preference, taste and season with more salt and pepper to your liking.
Assemble the Dish: If you’re using a baking dish, transfer the mushroom and spinach mixture into it, spreading it evenly. Place the seared chicken breasts gently on top, nestling them into the veggies. Finally, pour that luscious creamy sauce evenly over everything, making sure the chicken and veggies are generously coated.
Bake to Perfection: Pop the dish into your preheated oven, uncovered, for about 20-25 minutes. You’re looking for the chicken to reach an internal temperature of 165°F (74°C). The sauce should bubble around the edges, inviting you to dig in!
Broil for a Golden Finish (Optional): For that show-stopping touch, you can broil the dish for 2-3 minutes to achieve a beautiful golden top. Just keep a close eye on it to prevent burning. Once it’s done, let it rest for about 5 minutes to lock in those flavors.

Storing & Reheating
This dish stores beautifully! Allow leftovers to cool to room temperature, then transfer them to an airtight container. You can keep it in the fridge for up to 4 days. For longer storage, consider freezing it in portions for up to 3 months. When you’re ready to enjoy again, simply defrost in the fridge overnight and reheat in the oven at 350°F (175°C) until warmed through. Just a heads-up: the texture may change slightly, but a quick stir after reheating helps refresh the creamy sauce!
Chef’s Helpful Tips
- Avoid overcrowding the skillet when searing the chicken; this ensures proper browning and prevents steaming.
- Make sure your cream cheese is at room temperature for a smoother sauce without lumps.
- Use fresh herbs whenever possible—they elevate the dish remarkably compared to dried.
- If you’re short on time, a rotisserie chicken can be a fantastic shortcut; just add it to the dish during assembly for a quick weeknight dinner.
- Want to enhance the sauce? Add a splash of lemon juice or a tablespoon of Dijon mustard when whisking the ingredients together.
