10 Easy Keto Chicken Casserole Recipes Even Picky Eaters Will Love

Dinner battles end here. These 10 keto chicken casserole recipes are so creamy, cheesy, and comforting that your kids will ask for seconds—without ever realizing they’re eating low-carb.

If you’re juggling a busy schedule and a family with differing tastes, the ketogenic diet can feel like a solo mission. But casseroles are the great unifier: they’re one-dish wonders that hide healthy ingredients, freeze beautifully, and satisfy even the pickiest palates. We’ve rounded up the best easy keto chicken casserole recipes that are ready in under 45 minutes, use minimal cleanup, and pack in the flavor without the carbs.

Why Casseroles Are the Secret Weapon for Keto Families

Casseroles solve the "what’s for dinner?" crisis by combining protein, fat, and veggies in a single baking dish. They are inherently flexible, making them perfect for using up leftover rotisserie chicken (a staple from Costco or Walmart) and odds-and-ends cheese from the fridge. For keto success, you need high-fat, moderate-protein meals, and casseroles deliver exactly that—typically clocking in at 5-8g net carbs per serving.

The key is to swap out carb-heavy binders like pasta or potatoes for cauliflower rice, broccoli, or even crushed pork rinds for a crunchy topping. This keeps the texture familiar but the macros on point.

1. Classic Cheesy Chicken Broccoli Casserole

This is the gold standard for picky eaters. It’s creamy, cheesy, and comforting. Steam 4 cups of broccoli florets until just tender, then combine with 3 cups of shredded cooked chicken and 1.5 cups of shredded sharp cheddar. Stir in a sauce made from 8 oz of softened cream cheese, 1/2 cup of heavy cream, and 1 tsp of garlic powder. Bake at 375°F for 20 minutes until bubbly.

Pro Tip: For a golden, crispy top that mimics a breadcrumb finish, crush 1 cup of pork rinds and mix with 2 tbsp of melted butter. Sprinkle over the casserole before baking.

2. Buffalo Chicken Dip Turned Casserole

Love game-day dip? Turn it into a dinner. Combine 4 cups of shredded chicken with 1 cup of buffalo sauce (check labels for zero sugar), 8 oz of cream cheese, and 1/2 cup of ranch dressing. Fold in 1 cup of shredded mozzarella and top with crumbled blue cheese. Bake at 350°F for 25 minutes. Serve with celery sticks or pork rinds for dipping.

This recipe is a crowd-pleaser and uses ingredients you likely already have. It’s also a fantastic way to use up leftover chicken from a Sunday roast.

3. Low-Carb Chicken Alfredo Casserole

Pasta cravings? This one stops them cold. Sauté 2 cups of sliced mushrooms and 3 cloves of garlic in butter. Mix with 3 cups of cooked chicken, 1 jar of Rao’s Alfredo sauce (or make your own with heavy cream and parmesan), and 1.5 cups of cauliflower florets. Top with 1 cup of mozzarella and bake at 375°F for 25 minutes.

Quick Tip: To save time, use a bag of frozen cauliflower rice and microwave it for 5 minutes before adding. This cuts your prep time down to just 10 minutes.

4. Taco Chicken Casserole with a Crunch

Who says you can't have crunch on keto? Brown 1 lb of ground chicken with 1 packet of taco seasoning. Mix with 1/2 cup of salsa (use a low-sugar brand like Herdez), 4 oz of cream cheese, and 1 cup of shredded Mexican cheese blend. Pour into a baking dish and top with crushed pork rinds mixed with a little melted butter. Bake at 350°F for 20 minutes. Top with sliced avocado, sour cream, and fresh cilantro.

For the best results, use a Lodge 12-Inch Cast Iron Skillet to brown the meat and then transfer directly to the oven. This skillet is a workhorse—it heats evenly and goes from stovetop to oven without a fuss, meaning one less dish to wash.

5. Chicken Bacon Ranch Casserole

This is the ultimate "safe" food. Cook 6 slices of bacon until crispy, then crumble. Mix 3 cups of shredded chicken with 1/2 cup of ranch dressing (make your own with buttermilk and herbs for cleaner ingredients), 4 oz of cream cheese, and 1 cup of shredded cheddar. Fold in the bacon and bake at 375°F for 20 minutes. The smoky, savory flavor is a guaranteed hit.

Storage: This casserole freezes exceptionally well. Assemble it in a disposable foil pan, cover tightly, and freeze for up to 3 months. Thaw overnight in the fridge and bake as directed—perfect for busy weeknights.

6. Creamy Spinach Artichoke Chicken

Elevate your weeknight dinner with this restaurant-quality dish. Sauté 1/2 cup of chopped onion in butter. Add 10 oz of frozen chopped spinach (thawed and squeezed dry) and 1 can of artichoke hearts (drained and quartered). Stir in 8 oz of cream cheese and 1/2 cup of sour cream. Mix with 3 cups of chicken and top with 1 cup of parmesan. Bake at 375°F for 25 minutes until golden.

This recipe is rich and elegant, but simple enough for a Tuesday night. It’s also a great way to sneak extra greens into your family’s diet.

7. Pizza Chicken Casserole

Kids love pizza, and this casserole delivers all the flavor without the crust. Layer 3 cups of shredded chicken in a baking dish. Top with 1 cup of marinara sauce (look for no-sugar-added), 1.5 cups of mozzarella, and your favorite toppings like pepperoni, sliced olives, and bell peppers. Bake at 375°F for 20 minutes until the cheese is melted and bubbly.

Allow each family member to customize their own portion with extra toppings—this makes dinner interactive and fun, which is a huge win for picky eaters.

8. Chicken Enchilada Casserole (Low-Carb Style)

Skip the tortillas and use a layer of roasted poblano peppers or even thinly sliced zucchini instead. Mix 3 cups of chicken with 1 cup of green enchilada sauce (check for no added sugar) and 1/2 cup of sour cream. Layer the mixture with the peppers and 1.5 cups of shredded Monterey Jack cheese. Bake at 350°F for 25 minutes. Serve with a dollop of guacamole.

9. Cauliflower Mac & Cheese with Chicken

This is the ultimate comfort food hack. Steam 4 cups of cauliflower florets until fork-tender. In a saucepan, melt 2 tbsp of butter and whisk in 2 tbsp of almond flour. Slowly add 1.5 cups of heavy cream and 2 cups of shredded sharp cheddar, stirring until smooth. Combine the sauce with the cauliflower and 2 cups of diced chicken. Bake at 375°F for 20 minutes.

Pro Tip: To get a perfectly smooth cheese sauce without lumps, use a good whisk and add the cheese gradually. A high-quality Instant Pot Duo Plus 6-Quart can also make this easier—use the sauté function to make the sauce and then pressure cook the cauliflower in the same pot for a true one-pot meal.

10. BBQ Chicken & Bacon Bake

Smoky, sweet, and tangy—this one hits all the notes. Toss 3 cups of chicken with 1/2 cup of sugar-free BBQ sauce (like G. Hughes) and 1 cup of shredded cheddar. Top with 6 slices of cooked, crumbled bacon and a sprinkle of red onion. Bake at 375°F for 20 minutes. The sauce caramelizes beautifully, creating a sticky, delicious glaze.

For a crispy, caramelized top, pop the casserole under the broiler for the last 2
