Picture it: rain tapping against the windows, a favorite playlist humming in the background, and the wonderful aroma of baked cheese and roast chicken filling the air. I remember tossing together what I had on hand—some cooked chicken, fresh broccoli, and a ridiculously generous handful of shredded cheddar—and discovering a dish so comforting, it quickly became my weeknight hero.

Ever since that night, this keto chicken casserole has held a special place in my heart (and my meal plan). If you’re looking for a fail-proof dinner packed with flavor, low in carbs, and guaranteed to make everyone at the table happy, you’re in for a treat with this recipe.


Why You’ll Adore This Easy Keto Chicken Casserole Recipe

There are plenty of low-carb casseroles out there, but this one is different—and I’ll tell you why:

  • Ridiculously Easy: Seriously, all you have to do is mix, bake, and eat. Perfect for busy nights when you need dinner on the table fast.
  • Ultimate Comfort Food: Creamy mayonnaise or cream cheese, melty cheese, and hearty chicken come together in the coziest way; it reminds me of childhood dinners (without all the carbs).
  • Family-Approved: Even the carb-lovers in my family ask for seconds. It’s creamy, cheesy, and has just enough broccoli to make you feel a bit virtuous.
  • Great for Meal Prep: Reheats like a dream (somehow it’s even better the next day), so I always make enough for lunch leftovers.

Ingredients You’ll Need for Easy Keto Chicken Casserole

Let’s keep things simple and satisfying. Here’s what you’ll need (a few quick tips sprinkled in!):

  • 3 cups cooked chicken, shredded or chopped
    Rotisserie chicken is my go-to for ease and flavor—plus, it saves so much time!
  • 1 cup mayonnaise or cream cheese
    Mayonnaise brings tang, cream cheese adds richness. Pick your favorite or whatever’s in the fridge.
  • 1 splash heavy cream (optional)
    For extra creaminess—use it if you have it on hand.
  • 2 cups broccoli florets, steamed or microwaved
    Fresh or frozen, whichever is easy. Steaming ahead keeps your casserole from turning watery.
  • 1–2 cups shredded cheese (cheddar or Monterey Jack)
    Cheddar gives a sharp bite; Monterey Jack melts into gooey bliss. Go half-and-half if you like.
  • Garlic powder or onion powder, optional (to taste)
    I love a sprinkle of garlic powder for savory depth. Onion powder works great too.

See? Simple keto ingredients, all easy to grab.


Step-by-Step Guide: Making the Perfect Easy Keto Chicken Casserole

Let’s walk through this together—promise, it’s easier than you think!

  1. Preheat your oven to 375°F.
    Starting with a hot oven ensures an extra bubbly, golden-brown topping.
  2. Grab a big bowl.
    Mix the cooked chicken, mayo or cream cheese, and the optional heavy cream. This stage is perfect for sneaking a quick taste!
  3. Add in the broccoli and shredded cheese.
    Sprinkle in garlic or onion powder if you want that extra savory kick.
  4. Mix everything together until it’s all well combined.
    You want that creamy sauce clinging to every bite of chicken and broccoli—no dry bits allowed!
  5. Spoon the mixture into a casserole dish.
    Top with a bit more cheese (because, why not?).
  6. Bake for 25–30 minutes.
    You’re looking for those delicious, bubbly edges and a golden cheese top that makes your kitchen smell like heaven.
  7. Let it rest for 5 minutes before diving in.
    This makes it easier to serve—and gives you time to wrangle everyone to the table.

My Secret Tips and Tricks for Easy Keto Chicken Casserole Success

After countless casserole nights, here’s what I’ve learned:

  • Use rotisserie chicken for exceptional flavor and no-cook convenience (so handy for keto meal prep!).
  • If you love a crunchy cheese top, swap the last five minutes for a broil—watch closely!
  • Letting the casserole rest after baking not only saves your tongue from burns (yep, learned that the hard way) but it also makes for tidier slices.
  • You can “hide” more veggies in there: think chopped spinach, a handful of cauliflower rice, or mushrooms. (Perfect for picky eaters or sneaky parents.)
  • For leaner casserole, try using half Greek yogurt + half mayo—it maintains creaminess but lowers calories.

Creative Variations and Ingredient Swaps

Want to make this easy keto chicken casserole your own? Go for it! Here are a few tasty twists:

  • Swap the protein: Turkey, leftover rotisserie chicken, or even cooked ground beef work beautifully (especially if you’re hunting for a new keto casserole recipe for meal rotation).
  • Change up the veggies: Cauliflower florets, sautéed zucchini, or wilted spinach are all low-carb and delicious options.
  • Cheese adventure: Try pepper jack for a bit of heat, Swiss for a milder twist, or a blend for maximum cheese magic.
  • Dairy-free? Use a vegan mayo and your favorite plant-based cheese.
  • Spice it up: Add a dash of smoked paprika, chili flakes, or even a squirt of sriracha to the creamy base.

How to Serve and Store Your Easy Keto Chicken Casserole

This casserole is pure keto comfort food, perfect for family dinner or meal prepping lunches:

  • Serving: Scoop out generous portions, and maybe add a sprinkle of fresh herbs (parsley or chives brighten every bite).
  • Pairing: I love pairing it with a crisp side salad, roasted asparagus, or even some keto garlic bread (hello, carb-friendly indulgence!).
  • Storing: Pop leftovers into an airtight container and refrigerate for up to 4 days.
  • Reheating: Gently reheat in the oven or microwave until hot and bubbly.
  • Freezing: Yep, this casserole freezes well! I often portion it out ahead of busy weeks—defrost in the fridge and reheat as usual.

FAQs: Your Top Questions About Easy Keto Chicken Casserole Recipe Answered

Can I use raw chicken instead of cooked chicken?
For best results, stick to cooked chicken. Using raw would require a longer bake time, and you risk a watery casserole. Shredded rotisserie or leftover baked chicken is perfect!

Is this recipe gluten-free?
Absolutely! It’s naturally gluten-free, thanks to the simple low-carb ingredients—no flour or breadcrumbs required.

Can I make this casserole ahead of time?
Definitely. Assemble everything up to a day in advance, cover, and keep it in the fridge. Pop it in the oven when you’re ready to bake (add an extra 5–10 minutes to the bake time if it’s coming straight from the fridge).

How do I lower the fat or calories?
Try using light mayo or Greek yogurt for the creamy base, reduced-fat cheese, and extra veggies.

Will picky eaters like this?
In my experience—oh yes! The cheesy, creamy goodness wins over kids and adults alike. Broccoli tends to mellow out after baking (and you can always chop it extra small if you’ve got a keen observer at your table).
