• Cooked shredded chicken: Use rotisserie chicken for maximum ease and flavor, or bake chicken breasts ahead of time and shred.
• Bacon: Just four slices, but the smoky, crisp bits amp up every single bite.
• Grated cheddar cheese: Divide it up for unbeatable meltiness inside and that irresistible golden top.
• Large eggs: These bind the casserole together, so every scoop holds together beautifully.
• Salt: Simple, but key—seasoning ensures every bite pops with flavor.
• Garlic powder: Infuses a mellow savory note that complements the chicken and veggies.
• Mustard powder: Don’t skip this! It wakes up the cheese for subtle tanginess.
• Cracked black pepper: Adds just the right amount of warmth and peppery balance.

How to Make Low Carb Chicken Casserole

Step 1: Preheat Your Oven

Begin by preheating your oven to 350 degrees Fahrenheit. Getting the oven ready early ensures it’s at the perfect temperature by the time you’ve assembled your casserole—no waiting around and hungry stares!

Step 2: Steam the Vegetables

Steam the riced cauliflower and broccoli florets until they’re both cooked through and fork-tender. You can do this quickly in a microwave or on the stovetop with a steamer basket. Once they’re soft but not mushy, drain off any extra liquid to keep your casserole from turning watery.

Step 3: Fry and Crumble the Bacon

In a skillet over medium heat, fry up your bacon until it’s extra crisp (the crunchier, the better). Set the bacon on paper towels to cool, then crumble it into small, savory pieces. This adds smoky richness and a bit of decadent crunch to your Low Carb Chicken Casserole.

Step 4: Mix Everything Together

Grab a large mixing bowl and combine the steamed cauliflower rice, broccoli, cooked shredded chicken, crumbled bacon, eggs, 2 1/2 cups of cheddar cheese, salt, garlic powder, mustard powder, and black pepper. Stir everything together until it’s thoroughly mixed—the eggs should evenly coat the other ingredients, making sure the casserole binds well as it bakes.

Step 5: Assemble the Casserole

Spread the mixture evenly into a 9×13-inch baking dish. Take the remaining 1/2 cup of cheddar and sprinkle it generously across the top for a bubbly, golden cheese finish. This layer is what makes the first scoop impossible to resist!

Step 6: Bake Until Golden

Slide the casserole, uncovered, into your hot oven and bake for 30 minutes. The cheese will melt into a golden layer, and the casserole will set into cheesy, savory perfection. When it’s done, it should be bubbling and irresistible smelling—don’t be surprised if everyone starts circling the kitchen!

Step 7: Serve and Enjoy

Let your Low Carb Chicken Casserole rest for just a few minutes before scooping and serving. This short wait helps everything set up, but honestly, it’s the hardest part because it smells so darn good!

How to Serve Low Carb Chicken Casserole

Garnishes

A sprinkle of fresh herbs—a little chopped parsley or chives—brings out the casserole’s colors and adds a burst of freshness. Try a few extra crumbles of crispy bacon or a light dusting of paprika to make it visually pop.

Side Dishes

This casserole is deeply satisfying, but pairing it with a simple green salad or some roasted asparagus keeps things light and colorful. If you want even more vegetables, slice up some cucumbers, tomatoes, or serve with a tangy slaw for added crunch and balance.

Creative Ways to Present

For a dinner party or brunch, scoop the casserole into individual ramekins before baking for instant personal portions—everyone loves their own little dish! Or, turn leftovers into a fun lunch by wrapping scoops in crisp lettuce leaves for a low-carb, hand-held twist.

Make Ahead and Storage

Storing Leftovers

Once your Low Carb Chicken Casserole has cooled, cover the baking dish tightly or transfer portions to airtight containers. It will keep well in the refrigerator for up to 4 days, making it a fantastic meal-prep option for busy weeks.

Freezing

You can absolutely freeze this casserole! Slice it into portions, wrap them well, and place in freezer-safe containers. It’ll stay delicious for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge for best texture.

Reheating

To reheat, just pop a portion (or the whole casserole) in the oven at 350 degrees until warmed through—usually about 20 minutes. You can also microwave individual servings, but baking helps the cheese get bubbly again.
