A creamy, low-carb chicken casserole packed with spinach, mushrooms, and melted mozzarella cheese. Perfect for keto, meal prep, or a comforting weeknight dinner.
Use thin-sliced chicken to ensure even cooking.
Spinach only needs a quick wilt — don’t overcook.
Soften cream cheese before mixing for easier blending.
Add red pepper flakes for a spicy kick.
Try different cheeses like provolone or cheddar for variation.
