Step‑by‑Step Instructions for BBQ Chicken Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that when your Whole30 BBQ Chicken Casserole is ready, it will bake evenly and achieve that perfect, slightly golden top. This small step sets the stage for delicious outcomes, so don’t skip it!
Step 2: Prepare the Sweet Potatoes
Peel and cube the sweet potatoes into small, uniform pieces, then place them in a large pot. Fill the pot with water and bring it to a boil, letting them cook for 20-25 minutes until they are fork-tender. Drain the sweet potatoes thoroughly, as excess water can affect the casserole’s consistency.
Step 3: Mash the Sweet Potatoes
In a mixing bowl, mash the drained sweet potatoes using ghee or butter until they reach a smooth and creamy texture. This step is crucial for creating a delightful base for your BBQ Chicken Casserole. Set the mashed sweet potatoes aside while you prepare the chicken.
Step 4: Cook the Chicken
Cube the skinless, boneless chicken breasts or thighs and heat a skillet over medium heat. Add olive oil and sauté the chicken pieces, seasoning them generously with sea salt and pepper. Cook for 2-3 minutes per side until the chicken is fully cooked and no longer pink in the center.
Step 5: Shred the Cooked Chicken
Once cooked, remove the chicken from the skillet and let it cool slightly before shredding it with two forks into bite-sized pieces. In a large bowl, mix the shredded chicken with crumbled bacon and half a cup of your favorite Whole30 BBQ sauce, ensuring every piece is well coated.
Step 6: Assemble the Casserole
Take a casserole dish and spread the creamy mashed sweet potatoes evenly across the bottom. Next, layer the chicken mixture over the sweet potatoes, then drizzle the remaining barbecue sauce on top. This layering creates a beautiful display of flavors and textures in your Whole30 BBQ Chicken Casserole.
Step 7: Bake the Casserole
Cover the casserole with foil and bake it in your preheated oven for about 25 minutes. During this time, the flavors will meld together, and the top will start to become slightly golden. Remove the foil during the last 10 minutes to allow the top to crisp up a bit more.
Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. If desired, garnish with freshly chopped red onion and cilantro for that extra pop of flavor. Now your Whole30 BBQ Chicken Casserole is ready to satisfy your family’s cravings for comfort food!

How to Store and Freeze BBQ Chicken Casserole
Fridge: Leftovers can be stored in an airtight container in the fridge for up to 4 days. Be sure to let it cool before sealing for optimal freshness.
Freezer: For longer storage, freeze the casserole before baking. Wrap tightly in plastic wrap and then in foil; it can last for up to 2 months.
Reheating: Thaw the casserole overnight in the fridge. Reheat in the oven at 350°F for about 25-30 minutes. If reheating directly from frozen, bake covered with foil for 45-60 minutes, removing the foil in the last 10 minutes.
Serving: Make sure to let the BBQ Chicken Casserole sit a few minutes after reheating, allowing flavors to settle before serving.
Expert Tips for BBQ Chicken Casserole
- Perfectly Cooked Chicken: Ensure chicken is cooked through before shredding; undercooked chicken can lead to a chewy texture in your casserole.
- Smooth Sweet Potatoes: For creamy mashed sweet potatoes, use a fork or potato masher; avoid using a blender, which can make them gummy.
- Watch Your Bake Time: Check your casserole at 20 minutes to prevent over-browning; each oven is different, and you want a golden top.
- Layering Flavors: Remember to evenly distribute the barbecue sauce throughout the layers; this ensures that every bite of your BBQ Chicken Casserole bursts with flavor.
- Ingredient Substitutions: Feel free to swap ingredients, like using butternut squash instead of sweet potatoes, while keeping the Whole30 guidelines intact.

Whole30 BBQ Chicken Casserole Recipe FAQs
What type of sweet potatoes should I use for the casserole?
I recommend using medium-sized sweet potatoes that are firm and free of dark spots or blemishes. Look for those that feel heavy for their size, as they tend to be sweeter and creamier. The natural sweetness of these potatoes will beautifully complement the savory BBQ chicken.
How should I store the leftovers of the BBQ Chicken Casserole?
Leftovers can be stored in an airtight container in the fridge for up to 4 days. To keep it fresh, make sure to allow the casserole to cool completely before sealing. When you’re ready to enjoy it again, reheat in the oven at 350°F for about 7-8 minutes until warmed through, or use the microwave for a quicker option.
Can I freeze the Whole30 BBQ Chicken Casserole?
Absolutely! For freezing, it’s best to wrap the unbaked casserole tightly in plastic wrap and then in foil. This will protect it from freezer burn and keep flavors intact. It can last up to 3 months. When you’re ready to bake, just thaw it overnight in the fridge and then bake it at 350°F for about 25-30 minutes, or bake directly from frozen covered with foil for 45-60 minutes.
What can I do if my sweet potatoes are still hard after boiling?
If you find your sweet potatoes aren’t as tender as needed after boiling, they may need a few more minutes in the pot. Ensure the water is boiling vigorously before adding them, and check for doneness with a fork after 25 minutes. If they are still firm, continue boiling and check every 2-3 minutes until they’re fork-tender.
Is this casserole allergy-friendly for my pets?
While the Whole30 BBQ Chicken Casserole is packed with nutritious ingredients for humans, it’s not suitable for pets, especially the garlic and onion present in the dish. Always check with your veterinarian before sharing human food with your furry friends.
Can I use rotisserie chicken instead of raw chicken?
Yes! Using rotisserie chicken is a fantastic time-saver. Just shred the already cooked chicken and mix it with the crumbled bacon and BBQ sauce in Step 5 of the instructions. This makes it even quicker to prepare your Whole30 BBQ Chicken Casserole, while still retaining that delicious flavor.
