Why Choose a Keto Diet?
The ketogenic diet has gained widespread popularity in recent years for its ability to promote weight loss, boost energy levels, and improve overall health. By drastically reducing carbohydrate intake and increasing healthy fat consumption, the body enters a metabolic state called ketosis, where it efficiently burns fat for fuel instead of relying on glucose. This shift can lead to a host of benefits, including reduced inflammation, better blood sugar control, and enhanced cognitive function.

For the Chicken:
- 770 g (27 oz) chicken breast, tenders, or chicken thighs (without skin)

Step-by-Step Instructions for Keto Creamy Chicken Casserole
Preheat Oven
Preheat your oven to 175°C (350°F). Grease a baking dish with butter or cooking spray.
Prepare Chicken
Season the chicken pieces with salt, pepper, and paprika. In a skillet over medium heat, cook the chicken until browned and cooked through. Remove from heat and set aside.
Prepare Sauce
In the same skillet, sauté the chopped onion and minced garlic until softened. Add the halved mushrooms and cook until they release their moisture and become tender. Stir in the heavy whipping cream, chicken broth, lemon juice, and nutmeg. Bring to a simmer and cook for 2–3 minutes until the sauce thickens slightly.
Assemble Casserole
In the prepared baking dish, layer the cooked chicken pieces. Pour the sauce mixture over the chicken, ensuring it’s evenly distributed. Sprinkle the Parmesan cheese over the top.

Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the casserole is bubbling and the top is golden brown.

Frequently Asked Questions (FAQs)
What can I substitute for heavy cream in the Keto Creamy Chicken Casserole?
If you’re looking for a dairy-free or lower-calorie option, you can substitute heavy cream with coconut cream, which will maintain a creamy texture and add a hint of coconut flavor. Another alternative is to use a combination of unsweetened almond milk mixed with almond flour or a thickening agent like xanthan gum to achieve a similar consistency. Additionally, cream cheese can be used, but you may want to thin it out with a bit of chicken broth for the right texture.
How can I adjust the spice level of the Keto Creamy Chicken Casserole?
To adjust the spice level, you can modify the amount of paprika and pepper in the recipe. For a milder flavor, reduce the spices or use sweet paprika instead of smoked. If you prefer a spicier dish, consider adding cayenne pepper, crushed red pepper flakes, or even diced jalapeños to the sauce. Just be sure to taste as you go to achieve your desired spice level.
Can I use frozen chicken for the Keto Creamy Chicken Casserole?
Yes, you can use frozen chicken for this casserole. However, it’s best to thaw the chicken beforehand to ensure even cooking. You can do this by leaving it in the refrigerator overnight or using the defrost setting on your microwave. If you’re short on time, you can also cook the chicken from frozen, but be sure to increase the cooking time and check that it reaches an internal temperature of 165°F (74°C) to ensure it’s fully cooked.
How do I enhance the flavor of the Keto Creamy Chicken Casserole?
To enhance the flavor, consider marinating the chicken in spices or herbs such as Italian seasoning, thyme, or rosemary for a few hours before cooking. You can also add a splash of white wine or a tablespoon of Dijon mustard to the sauce for added depth. Incorporating sautéed garlic and shallots will amp up the savory notes, and a sprinkle of lemon zest before serving can brighten the overall flavor profile.
