Ingredients
3 cups cooked chicken breast, shredded
4 cups fresh broccoli florets
1 cup shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1/2 cup cream cheese, softened
1 cup heavy cream
1/4 cup mayonnaise
2 cloves garlic, minced
1 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons olive oil
Instructions
Preheat the oven to 375°F (190°C).
Bring a large pot of water to a boil. Add the broccoli florets and cook for 2-3 minutes until bright green and slightly tender. Drain and immediately transfer to a bowl of ice water to stop the cooking process. Drain again and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for 1 minute until fragrant.
Add the softened cream cheese, heavy cream, mayonnaise, onion powder, salt, and black pepper to the skillet. Stir continuously until the cream cheese melts and the sauce is smooth and creamy.
Remove the skillet from heat and stir in the shredded cheddar cheese and half of the mozzarella cheese until melted and combined.
In a large mixing bowl, combine the shredded cooked chicken, blanched broccoli, and cheese sauce. Mix well to evenly coat the chicken and broccoli.
Transfer the mixture to a greased 9×13 inch baking dish. 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 cool for 5 minutes before serving.

Mastering Your Keto Chicken Broccoli Casserole
The Cheat Sheet for Ingredient Swaps — Keep the Creaminess, Lose the Fuss
Listen, keto cooking is all about flexibility without sacrificing texture or flavor. If you’re out of sharp cheddar, don’t sweat it—Monterey Jack or even a bold provolone can stand in nicely, bringing their own twist without throwing the whole dish off balance. Not a fan of heavy cream? Coconut cream is your dairy-free ace, but be warned—it adds a subtle tropical note, so keep your nose in the game. Mayonnaise is the secret weapon here, adding tang and fat, but swapping it for sour cream works too if you prefer a bit more zest. And for those who want to sneak in some extra greens, swapping broccoli for cauliflower or even Brussels sprouts—blanched just right—can shake things up while keeping carbs in check.
Why Blanching Broccoli Is Your Casserole’s MVP
The magic of that bright green broccoli and tender bite? It all hinges on blanching. Here’s the skinny: boiling the florets briefly then dunking them in ice water stops cooking cold turkey, locking in color and crunch. Skipping this step? You’re asking for limp, sad broccoli that blends into the background. Trust me, I’ve been there—trying to short-cut this step ended in a mushy mess more than once. Plus, blanching kicks out some bitterness, which means your cheese sauce gets to shine without competition. It’s like giving your broccoli a spa day before the casserole party.
Oops-Proof Your Casserole: Fixing Common Mishaps
Ever pulled a casserole out of the oven only to find it either dry as a desert or drowning in greasy puddles? Here’s the lowdown. Dry casserole? Usually, that means your sauce was too thin or you skimped on the mayo and cream cheese. Next round, don’t hold back on the fat—keto thrives on it. If your top layer burns before the inside is heated through, tent the dish with foil halfway through baking—keeping that golden brown glow alive without the charred edges. Puddles of oil? That’s the cheese breaking and sweating. Using a blend of cheeses with different fat content (sharp cheddar plus mozzarella) helps keep things stable. And please, patience is key—let the casserole sit for 5 minutes after baking; this resting period lets everything set up nicely, making your serving less of a hot mess and more of a dinner win.
Keto Chicken Broccoli Casserole FAQs
- Can I use frozen broccoli instead of fresh?
- Yes, you can! But thaw and drain it well to avoid sogginess. Frozen broccoli tends to release more water, which can turn your casserole a bit mushy — nobody wants that.
- How do I make this casserole creamier?
- Simple trick: swap half the heavy cream for full-fat coconut milk. It adds a lush texture and subtle richness without messing with your keto macros. Plus, coconut milk has a slight sweetness that contrasts nicely with the sharp cheddar.
- Can I prep this ahead of time?
- Absolutely. Assemble everything in your baking dish, cover tightly with foil, and refrigerate for up to 24 hours. When ready, just pop it into the oven and add a few extra minutes to the bake time since it’ll be cold straight from the fridge.
- Is this dish suitable for meal prep?
- For sure. Portion it out after it cools, then store in airtight containers. It reheats like a champ in the microwave or oven. I’ve had busy weeks saved by making this casserole in bulk — it’s like having a keto ace up your sleeve.
- Does this casserole freeze well?
- Yes, totally. Freeze in airtight containers for up to 2 months. When you’re ready to dig in, thaw overnight in the fridge then reheat. Just a heads-up: cheese may separate slightly upon reheating, so stir gently to bring it back together.
