Ingredients You’ll Need

- 1/2 cup sugar-free BBQ sauce: Choose a brand with 2g carbs or less per serving to keep it keto-friendly. If you can’t find sugar-free, homemade versions using low-carb ingredients are a hit.
- 1/2 cup cheddar cheese: Shredded sharp cheddar adds a robust flavor that pairs beautifully with the BBQ. Feel free to mix in other cheeses like pepper jack for a kick!
- 1/4 cup red onion: Thinly sliced, these add a slight crunch and sweetness. If you prefer, shallots could be a delicious alternative.

How to Make Easy Keto BBQ Chicken Casserole Recipe
Preheat and Prepare: Start by preheating your oven to 350°F (175°C). This temperature is key for achieving a bubbly, golden cheese topping. While the oven heats up, grab an 8×8-inch baking dish and set it aside for easy filling later.
Combine Chicken and Sauce: In a large mixing bowl, toss together your shredded chicken and sugar-free BBQ sauce until the chicken is fully coated. Make sure every piece gets enveloped in that smoky goodness. Next, throw in the sliced red onion and green bell pepper, mixing them until they’re well integrated with the chicken and sauce. This step brings all those lovely flavors together!
Transfer Mixture: Carefully spoon the chicken mixture into your prepared baking dish. Use a spatula or the back of a spoon to spread the mixture evenly across the bottom. This ensures that every bite gets a good mix of chicken, sauce, and veggies, so don’t rush this step!
Sprinkle with Cheese: Now, it’s time to top your casserole with shredded cheddar cheese. Be generous! Sprinkle it evenly over the chicken mixture, covering every nook and cranny. This will create that irresistible, gooey cheese layer that makes this dish so comforting.
Bake Until Golden: Place your dish in the preheated oven and bake for about 20 minutes. You’ll know it’s done when the cheese is bubbly and golden at the edges. The scent filling your kitchen will make it nearly impossible to wait! Let it cool for a few moments so the sauce can thicken slightly.

Storing & Reheating
After savoring your Easy Keto BBQ Chicken Casserole, storing leftovers is easy! Keep it at room temperature for no more than two hours. For longer storage, transfer it to an airtight container and refrigerate for up to 4 days. If you’d like to freeze it, use a freezer-safe container and it should stay good for up to 3 months. When you’re ready to enjoy again, reheat it in the oven at 350°F for about 15-20 minutes or until warmed through. Keep in mind the texture might change slightly, so a sprinkle of fresh cheese on top before reheating can help refresh that creamy goodness.
Chef’s Helpful Tips
- Make sure your shredded chicken is warm for easier mixing. Cold chicken could make it harder to combine with the sauce.
- Mix up your veggies! Feel free to toss in some zucchini or mushrooms if you want to add more texture.
- If you notice a dry texture, consider adding a splash of broth to moisten the casserole before baking.
- For an extra kick, add some spices like smoked paprika or a dash of cayenne.
- Preparing this casserole ahead of time? You can assemble it the day before and then simply pop it in the oven when you’re ready to eat.
With its simplicity and flavor, this Easy Keto BBQ Chicken Casserole is just the dish your weeknight needs. Enjoy it as is, or feel free to play around with the ingredients to suit your taste buds!
Recipe FAQs
Can I use other proteins instead of chicken?

Can I make this casserole in advance?
Yes, you can assemble everything and keep the casserole in the refrigerator for a day before baking. Just cover it tightly with foil or plastic wrap until you’re ready to bake. It may take a little longer to cook straight from the fridge.
Can I make this dairy-free?
Definitely! You can substitute with dairy-free cheese options available on the market or simply skip the cheese altogether and add additional veggies for extra flavors.
What are the best toppings for this casserole?
If you’re looking to add some finishing touches, consider topping with a sprinkle of fresh chopped parsley, sliced green onions, or even a dollop of sour cream after it comes out of the oven. These add a nice brightness and enhance the flavors beautifully.
