Low Carb Chicken Broccoli Casserole: A Comforting Keto Dinner

Ingredients List

• 2 pounds of boneless, skinless chicken breasts, trimmed and cut into 1-inch chunks
• 4 cups fresh broccoli florets (can substitute frozen, but fresh provides better texture)
• 1½ cups heavy cream
• 8 oz cream cheese, softened
• 2 cups shredded cheddar cheese, divided
• ½ cup grated Parmesan cheese
• 3 cloves garlic, minced
• 1 tablespoon olive oil
• 1 teaspoon dried thyme
• ½ teaspoon red pepper flakes (optional for heat)
• Salt and pepper to taste
• ¼ cup crushed pork rinds (for topping)

Timing

Prep time: 15 minutes
Cooking time: 30 minutes
Total time: 45 minutes

This keto chicken casserole saves you about 20 minutes compared to traditional casseroles that require pre-boiling pasta. Plus, the hands-on time is minimal – perfect for those busy weeknights when you’re juggling work emails and family demands.

Step-by-Step Instructions

Step 1: Prep Your Ingredients

Preheat your oven to 375°F. While it’s warming up, dice your chicken into bite-sized pieces – aim for roughly equal sizes to ensure even cooking. Chop your broccoli into florets if you’re using fresh.

Step 2: Cook the Chicken

Set a large pan on the stove and let a splash of olive oil warm up over medium-high heat. Once the oil is hot, drop in the chicken and sprinkle it with a little salt and pepper. Let it cook, stirring occasionally, until the meat turns opaque and loses that raw pink look—this usually takes around five to seven minutes. There’s no need to chase a deep golden color at this stage; the chicken will finish cooking and develop more flavor once it goes into the oven.

Step 3: Prepare the Cheese Sauce

In a saucepan over medium heat, combine heavy cream and cream cheese. Stir continuously until cream cheese melts completely (watch carefully to prevent scorching). Add 1½ cups of the cheddar, all of the Parmesan, garlic, thyme, and red pepper flakes. Stir until smooth and slightly thickened.

Step 4: Combine and Bake

Grab a 9×13 baking dish and spread the cooked chicken across the bottom, then scatter the fresh broccoli right on top. Pour the cheese sauce over everything and give it a slow, gentle mix so every bite gets coated without turning mushy. Finish it off with the rest of the shredded cheddar and a handful of crushed pork rinds for crunch. Slide the dish into the oven and bake for about 20 to 25 minutes, until the sauce is bubbling around the edges and the top turns lightly golden.

Healthier Alternatives for the Recipe

Looking to customize this keto broccoli chicken casserole? Try these swaps:

• Substitute cauliflower for half the broccoli to add variety

• For dairy-sensitive folks, coconut cream can replace heavy cream (though it adds a slight coconut flavor)
• Add a tablespoon of nutritional yeast for a boost of B vitamins and savory flavor

Serving Suggestions

This keto chicken dish is satisfying enough on its own, but if you feel like turning it into a fuller dinner, a few simple extras go a long way. A fresh arugula salad tossed with lemon and olive oil keeps things light and balances the richness. A few slices of avocado on the side add that creamy, feel-good fat we all love. If you enjoy a glass of wine with dinner, a crisp dry white—Sauvignon Blanc is a great choice—pairs nicely without overpowering the flavors. And if you’re feeding people who aren’t following keto, putting a loaf of crusty bread on the table keeps everyone happy.

Common Mistakes to Avoid

• Overcooking the broccoli: It continues cooking in the oven, so keep it slightly firm when mixing
• Pre-shredded cheese is convenient, but it’s treated with anti-caking agents that keep it from melting smoothly. Freshly grated cheese gives a better result.
• Forgetting to salt the chicken: Season each layer for depth of flavor
• Rushing the cheese sauce: Heat too high can cause separation

Storing Tips for the Recipe

One of the nice surprises about this keto casserole is that it tastes even better the next day. Any leftovers can be sealed in a tight container and kept in the fridge for up to four days without a problem. If you’re thinking ahead, divide it into single portions, tuck them into freezer-friendly containers, and freeze for as long as two months. When you’re ready to eat, warm it up in the microwave or the oven until it’s hot all the way through.

Conclusion

This low-carb chicken broccoli casserole proves that comfort food and keto aren’t mutually exclusive.

FAQs

Can this keto chicken casserole be prepared in advance?
Absolutely! Assemble everything up to 24 hours in advance, but wait to add the final cheese topping until just before baking.

Is this recipe suitable for meal prep?
Yes! It reheats beautifully and actually develops more flavor after a day in the fridge.

Can I use frozen broccoli instead of fresh?
You can, but thaw and drain it thoroughly first to prevent excess water from diluting your sauce.

How can I tell when the casserole is fully baked and ready to come out of the oven?
The top should be golden brown and bubbling around the edges, and the broccoli should be tender when pierced with a fork.

Is there a way to make this dairy-free while keeping it keto?
Try coconut cream with dairy-free cheese alternatives, though the texture will be slightly different.
