How to Make Creamy Low Carb Chicken Casserole
This Creamy Low Carb Chicken Casserole is a weeknight warrior, designed for maximum flavor with minimal effort. In under 30 minutes of prep, you’ll whip up a dish that’s incredibly tender, enveloped in a luxuriously rich, cheesy sauce. The simplicity is astonishing, yet the taste is sophisticated, making it a comforting and satisfying meal that feels like a treat.
Step-by-Step Instructions
Preheat your oven and prepare your skillet: Preheat your oven to 375°F (190°C). While the oven is heating, place a large oven-safe skillet (cast iron works beautifully here) over medium-high heat. Add the olive oil or butter to the skillet.
Sear the chicken: Once the oil is shimmering, add the cubed chicken to the hot skillet in a single layer. Be sure not to overcrowd the pan; cook in batches if necessary. Sear the chicken for 2-3 minutes per side, until it’s golden brown but not cooked through. Remove the chicken from the skillet and set it aside on a plate.
Sauté the aromatics: Reduce the skillet heat to medium. Add the chopped onion to the same skillet, scraping up any browned bits from the bottom. Cook the onion for 5-7 minutes, until softened and translucent. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
Build the creamy sauce: Add the softened cream cheese to the skillet with the onions and garlic. Stir until it begins to melt. Gradually whisk in the heavy cream and chicken broth until you have a smooth, unified sauce.
Season and simmer: Stir in the Italian seasoning, salt, and pepper. Bring the sauce to a gentle simmer, stirring occasionally, for about 3-5 minutes, allowing it to thicken slightly. Taste and adjust seasonings as needed.
Combine and bake: Return the seared chicken pieces to the skillet with the creamy sauce. Stir to coat the chicken evenly. Sprinkle the shredded cheddar cheese evenly over the top of the chicken and sauce mixture. Transfer the skillet to the preheated oven.
Bake until bubbly and golden: Bake for 20-25 minutes, or until the chicken is cooked through, the sauce is bubbly, and the cheese on top is melted and slightly golden brown.
Rest and serve: Once out of the oven, let the casserole rest for 5 minutes before serving. This allows the sauce to settle and makes serving easier. Garnish with optional toppings like fresh parsley, bacon bits, or sliced green onions if desired.

Storing and Reheating Tips
Refrigeration:
- Allow the casserole to cool completely at room temperature (no more than 2 hours).
- Transfer any leftovers to an airtight container or cover the original baking dish tightly with plastic wrap and then aluminum foil.
- Store in the refrigerator for up to 3-4 days.
Reheating:
- Oven Method (Recommended for best texture): Preheat your oven to 350°F (175°C). Place the desired portion of the casserole in an oven-safe dish. Cover loosely with foil to prevent the top from drying out. Heat for 15-20 minutes, or until heated through. Remove the foil for the last 5 minutes if you want to re-crisp the cheesy topping.
- Microwave Method: Place a portion of the casserole in a microwave-safe dish. Cover loosely with a damp paper towel. Heat on medium power in 1-minute intervals, stirring occasionally, until heated through. This method is quicker but may result in a slightly softer texture.
Freezing:
- For individual portions: Portion the cooled casserole into freezer-safe containers or heavy-duty freezer bags.
- For larger portions: Consider freezing the entire cooled casserole in its oven-safe dish (if deemed freezer-safe) or transfer to a freezer-safe container.
- Wrap tightly to prevent freezer burn.
- Frozen casserole can be stored for up to 2-3 months.
Thawing Frozen Casserole:
- The best method is to thaw overnight in the refrigerator.
- Once thawed, reheat using the oven or microwave methods described above. You may need to add a few extra minutes to the reheating time due to the initial chilling.
