Some dinners just feel comforting from the moment they come out of the oven. The kitchen smells incredible, the cheese is bubbling, and you already know the meal is going to be satisfying before you even take the first bite.
For me, creamy baked chicken dishes fall perfectly into that category.
Before switching to keto cooking, I used to rely on pasta-heavy casseroles or creamy rice dishes whenever I wanted something comforting. They tasted great, but they also came with a heavy carb load that didn’t leave me feeling my best.
That’s why I started experimenting with low-carb oven bakes built around simple ingredients like chicken, vegetables, and rich creamy sauces.
That experiment eventually led to this Keto Chicken Spinach and Mushroom Bake.
This dish combines tender baked chicken with sautéed mushrooms, fresh spinach, and a creamy garlic sauce, all finished with melted cheese. The flavors are rich and savory while the vegetables add freshness and balance.
What makes this recipe especially great is that it feels indulgent while still fitting perfectly into a keto lifestyle. It’s hearty enough to be a full dinner, easy enough for weeknights, and delicious enough to serve to anyone — even people who aren’t following keto.
If you’re looking for a comforting low-carb dinner that comes together easily and fills the house with amazing aromas, this chicken bake might quickly become one of your favorite recipes.

My Personal Experience
The first time I made this dish was on a weeknight when I wanted something warm and comforting but didn’t want to spend hours cooking.
I had chicken breasts in the fridge, mushrooms that needed to be used, and a bag of spinach that was about to reach its expiration date.
Instead of making three separate dishes, I decided to combine everything into one creamy oven bake.
The result surprised me.
The mushrooms brought deep savory flavor, the spinach added freshness, and the creamy sauce tied everything together perfectly.
Even better, the leftovers were just as delicious the next day.
Since then, this recipe has become one of my favorite low-carb dinners when I want something simple but satisfying.

Keto Chicken Spinach and Mushroom Bake Recipe
Ingredients
- chicken breasts – 2
- mushrooms – 1 cup
- spinach – 2 cups
- heavy cream – 1 cup
- cream cheese – 4 oz
- mozzarella – 1 cup
Instructions
- Begin by preheating your oven to 375°F (190°C) so it’s fully heated before the dish goes in. While the oven warms up, lightly grease a medium baking dish with a little butter or cooking spray. This prevents sticking and helps the chicken bake evenly.
- Place a large skillet over medium heat and add a small amount of oil or butter. Once the pan is warm, add the sliced mushrooms and cook them for about 4–5 minutes, stirring occasionally. The mushrooms will release moisture at first and then begin to brown slightly, which deepens their flavor.
- Add the fresh spinach to the skillet with the mushrooms. It may look like a lot at first, but spinach shrinks quickly as it cooks. Stir gently for 1–2 minutes until the spinach wilts and blends into the mushrooms. Remove the skillet from heat and set the mixture aside.
- Pat the chicken breasts dry with a paper towel, then season both sides with salt, pepper, and paprika. Place the seasoned chicken pieces evenly in the prepared baking dish so they form a single layer. This helps them cook evenly in the oven.
- In a mixing bowl, combine the heavy cream, softened cream cheese, minced garlic, and onion powder. Whisk the mixture together until it becomes smooth and creamy. If the cream cheese is firm, continue stirring until it fully blends into the sauce.
- Spoon the sautéed mushroom and spinach mixture evenly over the chicken in the baking dish. Spread it gently so each piece of chicken gets a good amount of vegetables on top.
- Slowly pour the prepared cream sauce over the chicken and vegetables, making sure it spreads across the entire dish. Then sprinkle the shredded cheese evenly over the top so it melts into a rich, golden layer while baking.
- Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the chicken is fully cooked and the cheese on top is melted and lightly golden. Once finished, remove the dish from the oven and let it rest for about 5 minutes before serving so the sauce thickens slightly and the flavors settle.
