Does Low-Carb Chicken, Spinach & Mushroom Bake Fit a highprotein Lifestyle?

Using cold cream cheese — Allow it to soften first so it melts smoothly into the creamy sauce.

Measuring cups and spoons — Help maintain consistent ingredient quantities and seasoning.

Storage Instructions

Allow the bake to cool slightly before storing.

Refrigerator: Store portions in airtight glass or BPA-free food containers for 3–4 days.
Freezer: Freeze individual portions in freezer-safe airtight containers for up to 2 months.
Reheating: Microwave individual portions in 60–90 second intervals, stirring or rotating as needed, or reheat covered in a 350°F (175°C) oven until hot.
Protein-friendly storage: Keeping individual portions sealed helps preserve the chicken and prevents unnecessary additions that could increase carbohydrates.
For the best texture, thaw frozen portions overnight in the refrigerator before reheating.

📝 Ingredients

Chicken & Vegetables

2 lbs boneless, skinless chicken breasts — cut into bite-sized pieces
4 cups fresh spinach — roughly chopped
8 oz mushrooms — sliced
1 tablespoon olive oil

Creamy Sauce

½ cup cream cheese — softened for easier melting
½ cup heavy cream
3 cloves garlic — minced
1 teaspoon Italian seasoning
½ teaspoon paprika
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon red pepper flakes — optional for heat

Cheese Topping

1 cup shredded mozzarella cheese
½ cup grated Parmesan cheese

Optional Garnish

Fresh parsley
Extra Parmesan
Freshly cracked black pepper
Red pepper flakes

Directions

1. Preheat the Oven

Preheat the oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish and set aside.

2. Season the Chicken

Pat the chicken dry with paper towels and cut it into evenly sized bite-sized pieces.

Season with paprika, onion powder, Italian seasoning, salt, and black pepper.

3. Brown the Chicken

Heat a large skillet over medium-high heat and add the olive oil.

Add the chicken in a single layer and cook for approximately 5–7 minutes, stirring occasionally, until golden on the outside and nearly cooked through.

Highprotein cooking tip: Avoid overcrowding the pan because this helps the chicken brown instead of steaming.

4. Cook the Mushrooms

Transfer the chicken to a plate.

Add the sliced mushrooms to the same skillet and cook over medium-high heat for 5–6 minutes.

Cook until the mushrooms are tender and most of their released moisture has evaporated.

5. Add the Garlic

Add the minced garlic and cook for 30–60 seconds over medium heat.

The garlic should become fragrant without turning dark brown.

6. Add the Spinach

Add the chopped spinach and cook for 1–2 minutes, stirring frequently, until it wilts.

If there is excess liquid in the skillet, continue cooking briefly until most of it evaporates.

7. Make the Creamy Sauce

Reduce the heat to low.

Add the softened cream cheese and heavy cream.

Stir continuously for approximately 2–3 minutes, until the cream cheese melts and the sauce becomes smooth and creamy.

8. Season the Sauce

Stir in the remaining Italian seasoning, paprika, onion powder, black pepper, salt, and optional red pepper flakes.

The sauce should be creamy and thick enough to coat the back of a spoon.

9. Combine Everything

Return the cooked chicken to the skillet.

Stir gently until the chicken, mushrooms, spinach, and sauce are evenly combined.

10. Transfer to the Baking Dish

Transfer the mixture to the prepared baking dish and spread it into an even layer.

11. Add the Cheese

Sprinkle the mozzarella evenly over the top, followed by the Parmesan.

Make sure the cheese covers the surface so it can become beautifully golden during baking.

12. Bake

Place the baking dish in the oven and bake uncovered for 20–25 minutes.

The casserole should be bubbling around the edges and the cheese should be completely melted.

The chicken should reach an internal temperature of 165°F (74°C).

13. Brown the Cheese

For a more golden top, switch the oven to broil for 1–2 minutes.

Watch closely because the cheese can brown quickly.

14. Rest

Remove the bake from the oven and let it rest for 5 minutes.

This allows the creamy sauce to settle slightly and makes serving easier.

15. Garnish and Serve

Finish with fresh parsley, freshly cracked black pepper, or a little extra Parmesan.

Serve warm.
