• 1/2 cup chicken broth: Lightens the cream a bit and introduces savory undertones to the casserole.

How to Make Keto Chicken and Broccoli Casserole

Step 1: Prepare Your Oven and Broccoli

First things first, preheat your oven to 375°F (190°C) to get it ready for baking your casserole into a golden masterpiece. While the oven warms up, steam your broccoli florets just until tender, about 5 to 7 minutes, so they stay vibrant and maintain a slight crunch that contrasts nicely with the creamy sauce.

Step 2: Mix the Main Ingredients

In a large mixing bowl, combine your cooked chicken, steamed broccoli, cheddar cheese, and Parmesan cheese. This colorful medley is the hearty foundation of your Keto Chicken and Broccoli Casserole, bursting with flavor, texture, and that gorgeous cheesy aroma already tempting your taste buds.

Step 3: Prepare the Creamy Sauce

In a separate bowl, whisk together the heavy cream, chicken broth, garlic powder, onion powder, plus salt and pepper to your liking. This blend will transform into a luscious, savory sauce that envelops the chicken and broccoli, unifying every forkful with velvety delight.

Step 4: Combine and Transfer

Pour the cream mixture over the chicken and broccoli combo and stir well to ensure every piece is coated in creamy goodness. Then, transfer this mixture to a greased baking dish so it bakes up evenly, making for a beautiful, bubbly casserole that’s ready to steal the show at your supper table.

Step 5: Bake and Enjoy

Pop your dish into the oven and bake for about 25 to 30 minutes until the casserole is bubbly and the top is a gorgeous golden brown. After baking, let it cool just a bit before serving—this rest time lets the flavors marry beautifully, ensuring each bite is as delicious as can be.

How to Serve Keto Chicken and Broccoli Casserole

Garnishes

Add a sprinkle of freshly chopped parsley or chives on top just before serving for a pop of color and a fresh herbal note that complements the casserole’s richness. A few red pepper flakes can also add a fun kick if you like a little heat.

Side Dishes

This casserole shines as a complete meal on its own, but if you want to round it out, consider serving it with a crisp, refreshing green salad or a simple cauliflower rice tossed with lemon zest to keep things keto-friendly and light.

Creative Ways to Present

For a family-style feast, serve the casserole straight from the baking dish for that cozy, communal vibe. Alternatively, plate individual portions and drizzle with a touch of olive oil or a dollop of sour cream to add extra creaminess and elegance when entertaining guests.

Make Ahead and Storage

Storing Leftovers

Leftovers of Keto Chicken and Broccoli Casserole can be stored in an airtight container in the refrigerator for up to three days. This makes for an easy, flavorful lunch or dinner ready to reheat without losing any of that creamy charm.

Freezing

If you want to prepare in advance, freezing this casserole works wonderfully. Just freeze it in a suitable container before baking, then thaw in the refrigerator overnight when ready to use. Bake as usual, adding a few extra minutes if needed to ensure it’s piping hot all the way through.

Reheating

To reheat, simply warm leftovers in the oven at 350°F (175°C) for about 15-20 minutes or until heated through. You can also use the microwave for a quicker option, though the oven will preserve the casserole’s beautiful texture best.

FAQs

Can I use frozen broccoli for this casserole?

Absolutely! Just thaw and drain frozen broccoli well before using it to avoid excess moisture which can make the casserole watery. Steaming frozen broccoli briefly also helps retain its texture in the dish.

What other cheeses work well in this recipe?

Feel free to experiment with cheeses like mozzarella for extra meltiness or Gruyère for a nutty flavor. Just keep the total amount around 1 1/2 cups to maintain the perfect creamy texture.

Is this casserole suitable for meal prepping?

Definitely! It holds up well in the fridge for a few days and can even be frozen. Make a big batch and enjoy several keto-friendly meals with minimal effort throughout the week.

Can I add other vegetables to the casserole?

Yes, keto-friendly veggies like cauliflower florets, spinach, or mushrooms would blend nicely. Just be mindful of moisture content and cook them slightly beforehand to avoid sogginess.

What’s the best way to shred the chicken?

Using two forks to pull apart cooked chicken breasts is quick and effective, but you can also pulse cooked chicken in a food processor for finer shredding. Cubed chicken works just as well if you prefer chunks over shreds.

Final Thoughts

I hope this Keto Chicken and Broccoli Casserole becomes one of your go-to comfort meals whenever you want something satisfying, cheesy, and packed with wholesome ingredients. It’s simple to prepare, kind to your low-carb lifestyle, and a dish that always feels like a special occasion. So go ahead and make it your own—I promise it will warm your heart and your kitchen!
