How to Make Cheesy Chicken Spinach & Mushroom Bake
1. Preheat the Oven
Preheat oven to 190ยฐC / 375ยฐF.
Lightly grease a baking dish with olive oil or cooking spray.
2. Season the Chicken
In a large bowl, combine the chicken pieces with:
olive oil
garlic powder
onion powder
paprika
black pepper
salt
Toss well to evenly coat every piece.
3. Sautรฉ the Vegetables (Optional but Recommended)
Heat a skillet over medium heat.
Add mushrooms and sautรฉ for 4โ5 minutes until softened and lightly golden.
Add minced garlic and cook for 30 seconds until fragrant.
Add spinach and cook just until wilted. Remove from heat.
(You can skip this step and bake everything raw, but sautรฉing adds deeper flavor and prevents excess liquid.)
4. Make the Creamy Sauce
In a bowl, whisk together:
cooking cream or heavy cream
Greek yogurt or cream cheese
minced garlic
Mix until smooth and creamy.
5. Assemble the Bake
In the prepared baking dish:
โข Spread the seasoned chicken evenly
โข Scatter sautรฉed mushrooms and spinach over the chicken
โข Pour the creamy sauce evenly over everything
โข Sprinkle generously with shredded cheese
6. Bake
Bake uncovered for 30โ35 minutes, until:
โข Chicken is fully cooked (165ยฐF / 74ยฐC internal temp)
โข Sauce is bubbling
โข Cheese is melted and lightly golden
For extra browning, broil for the last 2โ3 minutes.
7. Rest & Serve
Let the dish rest for 5 minutes before serving.
This helps the sauce thicken and makes serving easier.
Serving Suggestions
Serve this bake with:
โข Roasted vegetables
โข Steamed broccoli or green beans
โข Cauliflower mash
โข A fresh side salad
โข Zucchini noodles or shirataki noodles
Itโs rich enough to stand alone, but pairs beautifully with simple sides.
Tips for Best Results
โข Chicken thighs give juicier results; breasts are leaner
