Description

This keto creamy chicken casserole combines juicy chicken, mushrooms, and a rich Parmesan cream sauce, baked to golden perfection for a comforting low-carb meal.


Ingredients

  • 770 g chicken breast, tenders, or boneless skinless thighs
  • Salt to taste
  • 1 tsp ground paprika
  • Pepper to taste
  • 80 g onion, finely chopped
  • ¼ tsp garlic, minced
  • 500 g mushrooms, halved
  • 220 ml heavy whipping cream
  • 50 g Parmesan cheese (divided)
  • 220 ml chicken broth or water
  • 2 Tbsp lemon juice
  • ¼ tsp nutmeg
  • 1 Tbsp chopped parsley for garnish

Instructions

  1. Preheat the oven to 175 °C (350 °F) and grease a baking dish with butter or cooking spray.
  2. Season the chicken with salt, pepper, and paprika. Cook in a skillet over medium heat until browned and fully cooked. Remove and set aside.
  3. In the same skillet, sauté onion and garlic until fragrant. Add mushrooms and cook until softened.
  4. Pour in the heavy cream, chicken broth (or water), lemon juice, and nutmeg. Simmer until the sauce slightly thickens.
  5. Arrange the cooked chicken in the baking dish. Pour the sauce over it and sprinkle Parmesan cheese on top.
  6. Bake for 25–30 minutes until bubbling and golden brown. Let rest before garnishing with chopped parsley and serving.

Notes

  • Swap chicken breasts for boneless thighs for extra flavor.
  • Add spinach or broccoli for more texture and nutrients.
  • Try mozzarella or cheddar instead of Parmesan for variety.
  • Use coconut cream and dairy-free cheese for a dairy-free version.
  • Thicken the sauce with a bit of xanthan gum if desired.
