Ingredients Breakdown for Keto Broccoli Chicken Casserole

Essential Ingredients for the Best Low Carb Chicken Casserole

The beauty of this keto broccoli chicken casserole lies in its simplicity. With just a few low carb, high fat ingredients, you get a dish that’s creamy, satisfying, and packed with nutrients. Let’s take a closer look at each component and why it works perfectly for a keto-friendly meal.

Chicken: The Protein Powerhouse

You can use:

• Shredded chicken breast for a leaner option
• Chicken thighs if you prefer more fat and flavor
• Leftover rotisserie chicken for convenience

No matter which cut you choose, chicken delivers the protein punch needed to support your keto macros. Plus, it absorbs the cheesy sauce like a dream.

Broccoli: A Low Carb Nutrient Bomb

Broccoli is a keto vegetable staple for a reason:

• It’s rich in fiber, which helps keep net carbs low
• It adds a slight crunch and freshness to balance the rich sauce
• One cup contains just 4g net carbs and is loaded with Vitamin C and K

Pro tip: Steam or blanch your broccoli florets before baking to ensure perfect texture.

Creamy, Cheesy Goodness: The Sauce Base

This casserole gets its irresistible texture from a combo of high-fat, low-carb dairy. Here’s what you’ll need:

• Cream cheese: Thick, tangy, and the glue that holds it all together
• Heavy cream: Adds richness and helps thin the sauce slightly
• Sour cream: Brings that little zing to cut through the fat
• Shredded cheddar: Melts beautifully and creates that golden-brown top

You can also toss in a handful of mozzarella or parmesan for extra meltiness and depth.

Seasonings That Bring It to Life

Don’t underestimate the power of spices! This keto casserole uses:

• Garlic powder for savory depth
• Onion powder (sparingly) to avoid carbs
• Salt and pepper to taste
• Italian seasoning or paprika for extra kick

Keep it simple, but don’t be afraid to experiment!

Optional Toppings for Crunch and Flavor

Want a little crunch without the carbs? Try:

• Crushed pork rinds (as a breadcrumb substitute)
• Extra cheese layer for a bubbly crust
• Chopped green onions for freshness (sparingly)

These finishing touches elevate your cheesy keto chicken bake to next-level comfort food.

Easy Low Carb Casserole in Just 5 Steps

This keto broccoli chicken casserole is simple enough for weeknights but comforting enough to feel like a weekend indulgence. With just a few steps, you’ll have a bubbling dish of cheesy, low carb comfort food ready to devour.

Let’s break it down so you can get cooking fast and keto right.

Step 1: Prep Your Chicken the Keto Way

If you don’t already have cooked chicken, now’s the time to get it ready.

You can:

• Boil or bake chicken breasts and shred with forks
• Use leftover chicken from another meal
• Buy a no-sugar-added rotisserie chicken and shred it

Keep your portion around 2 to 3 cups of shredded chicken for the perfect balance of protein and sauce.

Step 2: Steam or Blanch the Broccoli

Broccoli should be vibrant and tender, not mushy. Here’s how:

• Cut into small, bite-sized florets
• Steam for 3–4 minutes or blanch in boiling water for 2 minutes
• Immediately transfer to ice water (optional) to keep that fresh green color

This helps retain some crunch and keeps your keto casserole from turning soggy.

Step 3: Make the Creamy Keto Cheese Sauce

Now for the best part the sauce!

In a saucepan over medium heat:

1. Add 4 oz of cream cheese and ½ cup heavy cream
2. Stir until melted and smooth
3. Mix in ¼ cup sour cream, 1 cup shredded cheddar, and spices like garlic powder and salt
4. Keep stirring until the cheese is fully melted and the sauce is silky

Optional: Add a pinch of paprika or mustard powder for depth.

This creamy blend holds everything together and delivers that rich, cheesy texture you crave in a low carb chicken casserole.

Step 4: Assemble the Casserole Like a Pro

Time to bring it all together:

• Preheat your oven to 375°F (190°C)
• In a greased 9×13 baking dish, layer the chicken, then broccoli, then pour the cheese sauce over everything
• Gently mix so everything is evenly coated
• Top with a generous layer of shredded cheese

Optional: Sprinkle with crushed pork rinds or low-carb breadcrumbs for a crunchy finish.

Step 5: Bake, Rest, and Serve

Pop it into the oven and:

• Bake uncovered for 20–25 minutes, until bubbly and golden
• Let it rest for 5–10 minutes before serving this helps everything set

And voilà! Your keto broccoli chicken casserole is ready to wow your taste buds.
