• 1 large package sliced mushrooms
• 8 ounces shredded mozzarella cheese
• 1 container green onion cream cheese
• ¼ cup olive oil

How to Make Chicken Spinach and Mushroom Low Carb Oven Dish

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil.

Step 2: Arrange the Chicken

Place the chicken breasts in a single layer in the prepared baking dish.

Season both sides lightly with:

• Herb and garlic seasoning
• Freshly ground black pepper

Step 3: Add the Vegetables

Spread the fresh baby spinach evenly over the chicken.

Scatter the sliced mushrooms across the top.

As the casserole bakes, the spinach will wilt beautifully while the mushrooms become tender and flavorful.

Step 4: Prepare the Creamy Sauce

In a medium bowl, soften the green onion cream cheese until smooth.

Whisk together:

• Softened cream cheese
• Olive oil
• Chicken broth

Continue whisking until the mixture is smooth and pourable.

Pour the sauce evenly over the chicken and vegetables.

Step 5: Bake Covered

Loosely cover the baking dish with aluminum foil.

Do not seal the foil tightly, allowing a little steam to escape.

Bake for 20 minutes.

Step 6: Continue Baking

Remove the foil.

Bake uncovered for an additional 20 to 25 minutes, or until the chicken is nearly cooked through.

Step 7: Add the Cheese

Sprinkle the shredded mozzarella evenly over the top.

Return the dish to the oven and bake uncovered for another 10 minutes, or until the cheese is fully melted, bubbly, and lightly golden.

Step 8: Rest and Serve

Allow the casserole to rest for 10 minutes before serving.

This helps the creamy sauce thicken and makes serving easier.

Tips for the Best Low Carb Chicken Bake

Use thin chicken breasts so they cook evenly.

Pat the mushrooms dry before adding them to reduce excess moisture.

Do not overbake the chicken to keep it tender and juicy.

Allow the cream cheese to soften before mixing for the smoothest sauce.

Freshly shredded mozzarella melts better than pre-shredded cheese.

For extra color, broil the casserole for 2 to 3 minutes after adding the cheese.

Delicious Variations

Bacon Chicken Spinach Bake

Add cooked, crumbled bacon before topping with mozzarella.

Garlic Parmesan Chicken Bake

Mix grated Parmesan cheese into the sauce for extra richness.

Italian Chicken Casserole

Season with Italian herbs and add a sprinkle of Parmesan before baking.

Spicy Chicken Bake

Add crushed red pepper flakes or diced jalapeños for a little heat.

Broccoli Chicken Bake

Replace part of the spinach with fresh broccoli florets.

Three-Cheese Chicken Bake

Use a combination of mozzarella, Monterey Jack, and Parmesan cheeses for even more flavor.

Frequently Asked Questions

Is this recipe keto-friendly?

Yes. The ingredients are naturally low in carbohydrates and high in protein and healthy fats, making this an excellent keto-friendly meal.

Can I use chicken thighs?

Absolutely. Boneless, skinless chicken thighs work wonderfully and stay especially juicy.

Can I substitute the cream cheese?

Yes. Garlic and herb cream cheese or plain cream cheese with chopped green onions both work well.

Why is my casserole watery?

Spinach and mushrooms naturally release moisture while cooking. Patting the mushrooms dry and allowing the casserole to rest before serving helps the sauce thicken.

Can I prepare this ahead of time?

Yes. Assemble the casserole up to one day in advance, cover, refrigerate, and bake when ready to serve.

Can I add more vegetables?

Definitely. Broccoli, zucchini, bell peppers, cauliflower, or asparagus all make excellent additions while keeping the dish low in carbs.
