You know those days when making dinner just feels, I dunno, overwhelming? The kind where you want something hearty, but your brain’s stuck on what, and you absolutely don’t want a kitchen mess? That’s exactly where this keto chicken broccoli casserole jumps in to save the evening. Cheesy, creamy, and loaded with veggies—plus it works for busy weeknights and fancier potlucks, too. I actually found a super-handy version of it right over here if you want to peek: Keto Chicken Broccoli Casserole. Anyway, let’s chat about making one everyone’ll love (even those picky weirdos who claim to not like broccoli, ha).

Easy chicken casserole recipe
Full honesty here: I never planned to become a casserole fan. Too many memories of floppy noodles and suspicious globs of “mystery” cheese from church potlucks. But this keto chicken broccoli casserole is a serious upgrade—like, it feels like five-star restaurant comfort food, but it’s honestly not that hard.
Here’s the beauty. Just steam some broccoli, shred up cooked chicken (I usually cheat and grab a rotisserie one at the store), then all those flavors get hugged together in a cheesy, slightly garlicky sauce. If you’ve got ten minutes to toss stuff in a bowl, you can make this. Bake it till it’s bubbling. The cheese gets all golden and perfect.
My best tip? Don’t overthink it. Frozen broccoli will work if fresh just isn’t happening…and if your casserole dish is kind of small, cram it in! More cheese on top isn’t against the rules. In fact, it’s kind of a life strategy at my house.
This recipe is a total weeknight lifesaver. I’ve made it three times already, and my husband keeps asking for more.

Tips & Tricks
Alright, now for the “why is my casserole never as good as yours?” questions I get all the time from friends (and, okay, my mom). If your first try tastes, well, blah? Here’s what probably helps:
First, don’t skip salting the broccoli. Otherwise it just tastes kinda green. Sprinkle salt and let it chill in the strainer for a few minutes. Another thing: mix the shredded chicken in really well, so every bite has some flavor. If you’re in a super rush, yes, you can use pre-cooked frozen chicken—just watch for extra sodium.
Cheese-wise, sharp cheddar packs a punch but you could try pepper jack or Gouda for wild flavor (try it! gets some serious “what’s in this?” at the table). Oh, and while you’re getting saucy, a dollop of sour cream or cream cheese makes the sauce even richer.
One funny thing? If the casserole gets a tad thick, splash a little heavy cream on before baking. It’s not “professional” but wow, it works.

Ingredient Notes
It’s time for a quick reality check on what’s actually going in this cheesy spinach and keto chicken broccoli casserole. I’ll be honest, the ingredient lineup doesn’t get wild, but you can absolutely swap and fiddle.
Chicken. Leftover roast works, but so does any cooked chicken. Poached, baked, whatever you’ve got. Just don’t use breaded chicken fingers (wife did that once…regret).
Broccoli. I cut the florets small, because nobody wants to fight a branch on their fork. Steam, microwave, whatever.
Cheese. I lean hard into sharp cheddar, but if you love cheese (and who doesn’t?), sprinkle on some mozzarella or parmesan too.
Cream. Heavy cream keeps it low carb and rich. If you don’t have it, half-and-half works, but it’s less decadent.
Spinach. A couple handfuls fresh, wilted, or frozen (squeeze it dry!) go straight in with everything else.
Extras? Garlic powder, onion powder…you know the drill.
Basically, if you can chop it and it won’t wreck the carbs, toss it in.
Variations
There’s honestly so many riffs you could spin on this keto chicken broccoli casserole. My cousin puts little bacon crumbles on top—next level. I’ve even used turkey after Thanksgiving, and my neighbor (who thinks he’s a grill master) swaps cheddar for pepper jack, adds jalapeños, and pretends it’s Tex-Mex. Cool, right?
Some brave souls roast mushrooms and stir ’em in. You can ditch the spinach if greens aren’t your thing. Or, swap the sauce: mix up your cheesy base with a scoop of pesto for a Mediterranean twist.

Bottom line: all you need is cooked chicken, broccoli, cheese, and your imagination.
