A simple one-dish meal, this healthy keto chicken casserole is easy to assemble and practically bakes itself. It’s the ultimate weeknight dinner!
This chicken casserole is healthy, keto, filling, and so easy to make. If you have precooked chicken, it’s ready in just a few minutes! But even if you need to cook the chicken first, this recipe is still very easy to make.
Casseroles are the perfect weeknight dinner!
I love casseroles because they make my life so easy. You throw a few ingredients into the casserole dish, bake, and voila – dinner is ready! Plus they are tasty, and everyone loves them, kids and adults.
How do you make a homemade chicken casserole?
This casserole is the ultimate weeknight dinner – healthy, easy, quick and filling. It also has the added advantage of turning boring chicken breasts into something a bit more exciting.
Scroll down for the full recipe. Here are the basic steps:
- You bake the chicken, then cube it.
- Mix the chicken cubes with a creamy homemade sauce.
- Top with cheese and bake.
- Then sprinkle scallions and bacon bits on top for extra flavor and a gorgeous presentation.
Is it healthy?
I think it is. Chicken, the main ingredient in this recipe, is very nutritious.
Unless you have a specific issue that requires you to minimize saturated fat or dietary cholesterol, sour cream and cheese should be fine. Some current research even says that for most healthy people, full-fat dairy is healthy.
And the bacon, while not ideal nutritionally (but probably not terrible), is used here in a small amount, as a condiment, so I think it’s fine. However, you could definitely omit it if you’d rather not consume processed meat.
Is this a creamy chicken casserole?
It’s just creamy enough for my taste, and my family likes it this way too. But if you’d like it to be extra creamy, I suggest you increase the mayonnaise and sour cream to 1/3 cup each.
What to serve with this dish?
I usually serve it with a green vegetable, such as steamed broccoli or spicy green beans, to round out the meal.
If you’d like, you can very lightly steam small broccoli florets and mix them into the casserole before the final stage of baking, making it a complete meal. If you do, I suggest you increase the mayonnaise and sour cream to 1/3 cup each.

What to do with leftovers of this keto chicken casserole?
If you have leftovers, you can keep them in the fridge for about 3 days, in a sealed container. Gently reheat them, covered, in the microwave on 50% power, to avoid drying out the chicken.
Chicken Casserole
INGREDIENTS
Chicken:
- 4 (8 oz) boneless skinless chicken breasts
- Avocado oil spray
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
Sauce:
- ¼ cup avocado oil mayonnaise (1/3 cup for a creamier casserole)
- ¼ cup sour cream (1/3 cup for a creamier casserole)
- 1 tablespoon Dijon mustard
- 1 tablespoon minced garlic
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme
- ½ teaspoon paprika
- ¼ teaspoon cayenne pepper
- 1 cup shredded sharp cheddar, divided
Topping:
- ¼ cup sliced scallions (green parts)
- ¼ cup bacon bits, room temperature
INSTRUCTIONS
- Preheat oven to 450 degrees F. Line a baking dish with parchment paper. Arrange the chicken breasts in the prepared pan. Spray with oil and sprinkle with salt and pepper. Bake until cooked through, about 20 minutes.
- Meanwhile, grease a 2-quart casserole dish. In a large bowl, mix together the mayonnaise, sour cream, Dijon mustard, minced garlic, salt, pepper, dried thyme, paprika, cayenne and ½ cup of the shredded cheddar.
- When the chicken is cooked, remove it from the oven but keep the oven on. Allow the chicken to slightly cool, until it’s easier to handle. Cut it into cubes, or shred it. Add the chicken cubes to the bowl with the mayonnaise-sour cream mixture and toss to coat.
- Transfer the mixture to the prepared casserole dish. Sprinkle with the remaining ½ cup of shredded cheddar. Bake until the cheese is melted, 5-10 minutes. If your casserole dish is broiler-safe, you can broil it instead, 6 inches below the broiler element (not directly below), for 30 seconds to 1 minute.
- Sprinkle the casserole with sliced scallions and bacon bits. Serve immediately.
