Ingredients
Scale
Chicken Base
- 6 cups cooked shredded chicken (rotisserie chicken works great for a quick shortcut!)
Sautéed Vegetables
- 1 tablespoon butter
- 1 tablespoon olive oil
- 0.5 small onion (thinly sliced)
- 1 clove garlic (minced)
- 12 ounces fresh white mushrooms (sliced)
Sauce
- 4 ounces beef broth (or chicken broth)
- 4 ounces cream cheese (softened and cubed)
- 2 ounces heavy cream
- 0.5 teaspoon salt (adjust to your preference)
- 0.25 teaspoon black pepper (adjust to your preference)
Topping
- 1 cup shredded mozzarella cheese
Instructions
- Prepare the baking dish and chicken: Preheat your oven to 400°F (200°C). Lightly grease a 9×13 inch baking dish with butter or oil. Spread the cooked shredded chicken evenly across the bottom of the dish, creating a uniform layer.
- Sauté onions and garlic: In a large skillet, heat the butter and olive oil over medium heat until shimmering. Add the thinly sliced onion and minced garlic, sautéing them for 3-5 minutes until the onions become soft and fragrant.
- Cook mushrooms: Add the sliced mushrooms to the skillet and cook for another 5-7 minutes until they are tender and have released their moisture, stirring occasionally to prevent sticking.
- Combine veggies and chicken: Spoon the cooked onion, garlic, and mushroom mixture evenly over the layer of shredded chicken in the baking dish.
- Make the creamy sauce: Using the same skillet, add the beef broth and softened cream cheese. Stir gently over medium heat while adding the heavy cream, salt, and pepper. Whisk continuously until the sauce becomes smooth and creamy. For best results, use an immersion blender to ensure a velvety texture.
- Assemble casserole: Pour the creamy sauce over the chicken and vegetable layers in the baking dish, making sure everything is evenly coated with the luscious sauce.
- Add cheese topping: Sprinkle the shredded mozzarella cheese evenly over the top of the casserole, forming a nice cheese blanket.
- Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes until the casserole is bubbling around the edges and the cheese is melted and golden brown.
- Serve warm: Remove from the oven and let it sit for a few minutes before serving. Enjoy this creamy, keto-friendly casserole as a hearty and comforting meal.
Notes
- Rotisserie chicken is a great time-saver and adds extra flavor.
- You can substitute beef broth with chicken broth to keep flavors lighter and more consistent with the chicken.
- Use an immersion blender for an ultra smooth sauce, but whisking is sufficient as well.
- Adjust salt and pepper to taste, especially if your broth is already salted.
- For a dairy-free version, substitute cream cheese and mozzarella with non-dairy alternatives.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
