Ingredients You’ll Need

These ingredients come together beautifully to make a creamy, cheesy casserole that’s brimming with protein and veggies. Make sure to pick fresh broccoli if you’re going that route, or fully thaw and drain the spinach so your casserole isn’t watery.

• Cooked chicken breast: Diced or shredded, leftover rotisserie chicken works amazing here.
• Bacon: Cooked and chopped crisp for a smoky crunch.
• Broccoli florets or frozen spinach: Both add nutrients and a great texture contrast.
• Garlic: Fresh minced garlic amps up flavor without overpowering.
• Ranch dressing: Adds creaminess and a hint of herbaceous tang.
• Mozzarella cheese: For gooey, melty goodness.
• Cheddar cheese: Provides sharpness and depth.
• Ranch seasoning mix (optional): Boosts flavor if you want an extra punch.

Variations

I like to tweak this Easy Low Carb Chicken Casserole Recipe depending on what’s in my fridge or how we’re feeling at the time. It’s super flexible, so you can definitely put your own spin on it.

• Veggies swap: I often swap the broccoli for mushrooms or zucchini for a different flavor and texture profile, and it works great.
• Dairy-free version: Use dairy-free cheese and Greek yogurt instead of ranch dressing, which keeps it creamy yet low carb.
• Spice it up: Adding a pinch of cayenne or chili flakes gives it a nice kick that my family loves on cooler evenings.
• Extra herbs: Fresh parsley or chives sprinkled on top after baking adds a burst of freshness I’ve grown to adore.

How to Make Easy Low Carb Chicken Casserole Recipe

Step 1: Prep Your Veggies Right

Start by preheating your oven to 375°F (191°C). If you’re using frozen spinach, thaw it completely and squeeze out every bit of water to avoid a soggy casserole. For broccoli, a quick 1-2 minute boil makes it bright green and tender without losing that nice crunch—then drain well. These little prep steps make a huge difference in texture and flavor!

Step 2: Mix It All Up

In a large bowl, combine your diced or shredded chicken, chopped crispy bacon, prepared veggies, garlic, ranch dressing, mozzarella, and half of the cheddar cheese. I like to sprinkle in a teaspoon or two of ranch seasoning mix here if I want that extra punch. You can mix everything in the bowl or save a dish by combining it straight in your casserole dish—either way works!

Step 3: Layer and Top

Transfer your mixture into a greased 9×13 inch casserole dish, spreading it evenly. Sprinkle the remaining mozzarella and cheddar cheese evenly over the top—you want that beautiful cheesy crust to bake up golden and bubbly.

Step 4: Bake to Perfection

Bake your chicken casserole for about 15 minutes or until it’s hot and bubbly with a golden cheese topping. Keep an eye on it near the end to avoid over-browning. Let it cool for a few minutes once out of the oven—it helps the casserole set and makes serving easier.

How to Serve Easy Low Carb Chicken Casserole Recipe

Garnishes

I usually sprinkle chopped fresh parsley or scallions on top right before serving for a pop of color and fresh flavor. Sometimes, a little extra shredded cheddar on the side is nice for cheese lovers. If you like heat, a dash of hot sauce or red pepper flakes works beautifully here too.

Side Dishes

This casserole stands beautifully on its own, but if you want something extra, I pair it with a crisp green salad or roasted cauliflower for more veggies without carbs. Garlic butter green beans are also a big hit in my house alongside this dish.

Creative Ways to Present

For dinner parties, I like to serve this casserole in individual ramekins – it feels extra special and controls portions perfectly. You can also sprinkle toasted almonds or crispy fried onions on top for some unexpected crunch that guests rave about.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container and refrigerate for up to 3 days. When reheated, the casserole keeps its creamy texture really well if you cover it loosely to retain moisture.

Freezing

This recipe freezes beautifully! I let it cool completely, then portion it into freezer-safe containers or bags. When you thaw and reheat it, the flavors come back just as vibrant—perfect for batch cooking.

Reheating

To reheat, I pop leftovers into a 350°F (175°C) oven covered with foil for about 15-20 minutes until warmed through. Microwaving works too, but I recommend adding a splash of water or covering to keep it moist.
