Sometimes, after a long day, you just want something warm and satisfying without the fuss—this keto chicken and broccoli cheesy casserole fits that need like a glove. It’s the kind of dish that fills the kitchen with a buttery, garlicky aroma, hinting at all the good things to come. The moment you slide the casserole into the oven, there’s this quiet anticipation, knowing you’ll soon have something bubbling and golden waiting for you.
I remember the first time I made this casserole; the house smelled like a cozy Italian bistro, but I was juggling a phone call and half-listening to a podcast, so I wasn’t sure if I’d overcooked the broccoli. It turned out perfectly tender, just somewhere between crisp and soft—the kind of texture I love. The cheese melted into every nook and cranny, wrapping the chicken and broccoli in a creamy hug. I didn’t know I needed this kind of comfort food until that evening.
- Combines protein and veggies in a rich, creamy sauce without the carbs.
- It’s simple—and that’s kind of the point; no complicated steps or rare ingredients.

If you’re nervous about making casseroles, this one is quite forgiving. A little extra cheese or a bit more broccoli won’t ruin it—in fact, it might even improve it. Just keep an eye on that golden brown finish; everyone’s oven behaves a little differently.

Description
A creamy, cheesy, and low-carb casserole featuring tender chicken, fresh broccoli, and a rich cheese sauce, perfect for a keto-friendly dinner.
Ingredients
3 cups cooked chicken breast, shredded
4 cups fresh broccoli florets
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 cup heavy cream
4 ounces cream cheese, softened
2 cloves garlic, minced
1/4 cup chopped yellow onion
2 tablespoons unsalted butter

Instructions
Preheat the oven to 375°F (190°C).
Steam the broccoli florets for 4-5 minutes until tender but still crisp. Drain and set aside.
In a medium skillet, melt the butter over medium heat. Add the chopped onion and minced garlic, sautéing for 3-4 minutes until translucent and fragrant.
In a large mixing bowl, combine the heavy cream, softened cream cheese, Dijon mustard, salt, black pepper, and paprika. Whisk until smooth.
Add the sautéed onions and garlic to the cream mixture and stir to combine.
Fold in the shredded chicken, steamed broccoli, cheddar cheese, and half of the mozzarella cheese into the creamy mixture.
Transfer the mixture to a greased 9×13 inch casserole dish, spreading it evenly.
Sprinkle the remaining mozzarella cheese and grated Parmesan cheese evenly over the top.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the cheese on top is golden brown.
Remove from the oven and let it rest for 5 minutes before serving.

Don’t worry about special equipment here; a good casserole dish and a skillet for sautéing get the job done. I usually serve this with a simple side salad or some roasted cherry tomatoes for a pop of freshness. Sometimes I swap out the cheddar for pepper jack if I’m feeling a bit adventurous, but honestly, the classic combo works best. If you want to add a little crunch, topping with crushed pork rinds before baking is a trick I haven’t fully tested but keep meaning to try.
FAQ
Can I use frozen broccoli? You can, but I prefer fresh because it holds up better after baking. If frozen, make sure to thaw and drain well to avoid sogginess.
Is this freezer-friendly? Yes, leftovers freeze well for up to two months. Just thaw overnight in the fridge before reheating.
Can I make it dairy-free? This one leans heavily on cheese and cream, so it’s a bit tricky to swap without losing the texture and flavor that make it special.
Give this casserole a try when you want that cheesy, creamy comfort without the carb overload. It’s the kind of meal you’ll find yourself craving again—especially on days when you need a little extra warmth from the inside out.
