Ingredients You’ll Need
- 1 lb cooked chicken: You can use shredded rotisserie chicken for convenience. This adds a juicy flavor; however, any well-cooked chicken will suffice if you prefer to shred it yourself.
- 1/2 cup sugar-free BBQ sauce: Look for a brand that has 2g carbs or less per serving to keep it keto-friendly. You can also make your homemade BBQ sauce if you prefer more control over the ingredients.
- 1/2 cup cheddar cheese: Shredded sharp cheddar is preferable for a rich, robust flavor. Alternatively, you can substitute it with mozzarella for a milder taste or use a dairy-free cheese if you’re avoiding dairy.
- 1/4 cup red onion: Thinly sliced for a sharp and slightly sweet bite. If red onion isn’t available, yellow onions can work, but the flavor will differ slightly.
- 1/4 cup green bell pepper: Sliced thin for crunch and a fresh taste. Feel free to experiment with other bell pepper colors for a sweeter flavor.
How to Make Easy Keto BBQ Chicken Casserole Recipe
Preheat and Prepare: Start by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly. As the oven warms up, prep an 8×8-inch baking dish by lightly greasing it. This will help prevent sticking and make serving much easier later on. The heat will soon fill your kitchen with delicious anticipation!
Combine Ingredients: In a large mixing bowl, combine the shredded chicken, sugar-free BBQ sauce, thinly sliced red onion, and green bell pepper. Use a spatula to mix everything thoroughly until the chicken is evenly coated in the tangy BBQ sauce. The colors will pop, and you’ll want to take a moment just to appreciate this vibrant combination.
Transfer Mixture: Carefully transfer the chicken mixture into your prepared baking dish. Spread the mixture into an even layer for even cooking. The beauty of layerings is that it creates a delightful medley of colors and flavors. Setting up this base prepares the canvas for what’s to come!
Sprinkle Cheese: Generously sprinkle the shredded cheddar cheese over the entire top of the casserole. This cheesy layer will melt into a golden crust, adding both flavor and visual appeal. Don’t be shy—make sure every corner is covered with cheese goodness. This is what takes it from great to extraordinary!
Bake to Perfection: Pop the casserole into your preheated oven and bake for about 20 minutes. You’ll know it’s ready when the cheese is melted, bubbling, and lightly golden at the edges. As the casserole bakes, keep your eyes peeled for that gorgeous, mouthwatering transformation taking place within your dish.
Let it Rest: After removing the casserole from the oven, let it rest for about 5 minutes. This waiting time allows the sauce to thicken slightly and makes serving easier. The aroma will tempt everyone nearby, so use this time to set the table or prepare any sides while the casserole cools just enough to be ready to enjoy!

Storing & Reheating
For leftovers, allow your Easy Keto BBQ Chicken Casserole to cool down, then store it in an airtight container in the refrigerator, where it will last for up to 4 days. If you want to keep it longer, consider freezing individual portions. Just be sure to wrap them tightly in plastic wrap and then place them in a freezer-safe container or bag. You’ll enjoy tasty leftovers for up to 3 months. When reheating, place it in the oven at 350°F (175°C) for about 15-20 minutes until warmed through. Keep in mind that the texture might change slightly, but a quick sprinkle of fresh cheese on top before reheating can help refresh that gooey goodness!
Chef’s Helpful Tips
- Ensure your chicken is well cooked and shredded to allow the sauce to distribute evenly throughout the casserole.
- For an extra kick of flavor, consider adding garlic powder, paprika, or even cayenne pepper to spice it up.
- If you’re prepping this dish ahead of time, assemble it without baking and cover tightly, refrigerating for up to 24 hours before baking.
- To keep the texture delightful, don’t overbake it; keep an eye on that cheese until it reaches golden perfection.
- Feel free to swap out the veggies to your preference. Broccoli or zucchini can also work wonders in this casserole.
