Ingredients You’ll Need
The ingredients for this recipe are wonderfully simple, each bringing its own special touch to the casserole. From the juicy chicken pieces to the crisp vegetables and rich cheeses, these components come together for a perfect balance of taste, texture, and color.
- 2 tablespoons olive oil: Great for sautéing and adding a silky richness to the dish.
- 1 pound boneless skinless chicken breasts (cut into bite-sized pieces): The protein star that keeps the casserole hearty and satisfying.
- 1 small onion (chopped): Adds a subtle sweetness and depth of flavor when cooked.
- 2 cloves garlic (minced): Brings a fragrant, savory punch to brighten the whole casserole.
- 1 medium head of broccoli (cut into florets): Offers a fresh crunch and vibrant green color.
- 1 medium zucchini (sliced): Adds moisture and a mild, fresh taste.
- 1/2 cup sour cream: Provides creamy tanginess that binds everything together.
- 1/2 cup mayonnaise: Enhances richness and keeps the casserole moist.
- 1 cup shredded cheddar cheese: Melts perfectly for gooey, cheesy goodness.
- 1/2 cup grated Parmesan cheese: Offers a sharp, nutty flavor to lift the dish.
- 1/4 teaspoon paprika: Adds warmth and a subtle smoky undertone.
- 1/2 teaspoon dried thyme: Introduces earthy, herbal notes to balance the flavors.
- Salt and black pepper to taste: Essential for seasoning and enhancing all ingredients.
- 1/4 cup crushed pork rinds or almond flour (for topping, optional): Creates a crunchy, golden crust to finish the casserole beautifully.
How to Make Easy Low Carb Chicken Casserole Recipe
Step 1: Brown the Chicken
Start by heating olive oil in a large skillet over medium heat. Add the bite-sized chicken pieces and cook them until they’re browned on all sides and completely cooked through, about 5 to 7 minutes. This step locks in juiciness and adds wonderful caramelized flavor. Once done, remove the chicken from the skillet and set it aside—soon it will reunite with fresh veggies and creamy cheese magic.
Step 2: Sauté Aromatics and Vegetables
Into the same skillet, toss in the chopped onion and minced garlic. Let them cook for 2 to 3 minutes, stirring occasionally, so their fragrances bloom and soften the base of your casserole. Next, add the broccoli florets and sliced zucchini. Sauté everything together for about 5 minutes until the veggies turn slightly tender but still maintain a pleasant firmness that adds texture to every bite.
Step 3: Combine the Creamy Mixture
While the veggies finish cooking, grab a large mixing bowl and stir together the sour cream, mayonnaise, shredded cheddar, grated Parmesan, paprika, dried thyme, salt, and black pepper. This creamy blend is what makes our casserole irresistibly rich and flavorful. Fold in the cooked chicken and vegetables gently, making sure each bit is coated in this cheesy, herby goodness.
Step 4: Assemble and Bake
Prepare a 9×13-inch baking dish by giving it a light grease to prevent sticking. Transfer the creamy chicken and vegetable mixture to the dish, smoothing the top evenly. If you like a crunchy, golden topping, sprinkle crushed pork rinds or almond flour over the surface. Pop your casserole into a preheated oven at 375°F (190°C) and bake for 20 to 25 minutes or until the top turns beautifully golden and bubbly. Let it rest for 5 minutes before serving—it’s worth the wait!
How to Serve Easy Low Carb Chicken Casserole Recipe
Garnishes
Simple fresh garnishes can elevate the casserole perfectly. Consider a sprinkle of freshly chopped parsley or cilantro for a bright herbaceous note. A few extra shreds of cheddar or Parmesan on top after baking can add a touch of extra cheesiness. For a bit of tang and crunch, a dollop of sour cream or a handful of sliced green onions works beautifully.
Side Dishes
This casserole is rich and filling on its own but pairs wonderfully with light, fresh sides. A crisp green salad with a zesty vinaigrette offers a refreshing contrast. Steamed asparagus or roasted Brussels sprouts add great texture and nutrition without overpowering the main dish. For a low-carb bread alternative, keto-friendly rolls or almond flour biscuits are exceptional choices.
Creative Ways to Present
Impress your guests by serving this casserole in individual ramekins, turning each portion into a personal cozy retreat. Alternatively, layer the mixture in clear glass baking dishes so the beautiful veggies and cheese are visible before baking—a feast for the eyes as well as the palate. To add a fun twist, top with avocado slices or a sprinkle of crushed red pepper flakes for some heat.
Make Ahead and Storage
Storing Leftovers
Leftovers store beautifully for up to 3 days when placed in an airtight container in the refrigerator. The flavors deepen as they sit, making your next meal just as satisfying as the first. When ready to eat, simply reheat gently to enjoy all the cozy, cheesy goodness again.
Freezing
This Easy Low Carb Chicken Casserole Recipe also freezes well, making it a fantastic option for meal prep. Cool the casserole completely, then wrap tightly with foil or place in a freezer-safe container. It will keep great for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating.
Reheating
To reheat, use a microwave for quick meals or bake in the oven at 350°F (175°C) for about 15 minutes until warmed through and bubbly again. A quick broil for a couple of minutes afterward can restore that delightful golden crust on top.
FAQs
Can I substitute the vegetables in this casserole?
Absolutely! The recipe is very flexible. Cauliflower or spinach work wonderfully, offering different textures and flavors while keeping it low carb. Feel free to mix and match based on what you have on hand and your personal preferences.
Is there a way to make this recipe spicy?
Definitely! Adding a pinch of red pepper flakes, diced jalapeños, or a dash of hot sauce into the creamy mixture can give your casserole a pleasant kick without overpowering the other flavors.
Can I use chicken thighs instead of breasts?
Yes, chicken thighs are a great alternative and bring a bit more juiciness and flavor. Just be sure to cook them thoroughly before combining with the other ingredients to avoid any undercooked spots.
Is the topping necessary?
The crushed pork rind or almond flour topping is optional but highly recommended for its added crunch and golden finish. If you prefer, you can skip it or substitute with your favorite low carb breadcrumb alternative.
