kcalIngredients
2 cups cooked chicken (shredded or cubed)
1 ½ cups chopped or steamed broccoli (or cauliflower rice/spinach)
1 cup shredded cheddar cheese
½ cup cream cheese, softened
½ cup sour cream or heavy cream
¼ cup grated parmesan cheese
2 cloves garlic, minced
1 tsp onion powder
Salt and pepper, to taste
Optional toppings: crushed pork rinds, almond flour, paprika, or chopped herbs
Step-by-Step Cooking Instructions
- Prepping the Chicken and Veggies
Start by cutting your boneless, skinless chicken breasts or thighs into bite-sized pieces. Season generously with salt, pepper, garlic powder, and dried herbs like oregano or thyme to boost flavor. In a large skillet, heat a bit of olive oil or butter over medium heat and sauté the chicken until it’s just cooked through and slightly golden — about 5 to 7 minutes. Remove the chicken and set it aside.
Next, in the same pan, add your low carb vegetables such as spinach, broccoli florets, or zucchini. Sauté the veggies until they soften and any excess moisture evaporates — this step helps prevent a watery casserole. If using leafy greens like spinach, cook until wilted.
- Making the Creamy Sauce
While the chicken and veggies cook, it’s time to prepare the luscious, low-carb creamy sauce. In a mixing bowl, combine softened cream cheese and sour cream or full-fat Greek yogurt. Stir until smooth and creamy. Then add shredded cheese — a blend of cheddar, mozzarella, and parmesan works beautifully — and mix well. For extra flavor, sprinkle in garlic powder, onion powder, and a pinch of salt and pepper.
This cheesy sauce will bind your casserole ingredients together with rich flavor and creamy texture while keeping the carbs low. - Assembling and Baking the Casserole
Now that your components are ready, preheat your oven to 350°F (175°C). In a large mixing bowl, combine the sautéed chicken, cooked veggies, and creamy cheese sauce, stirring until everything is well coated.
Transfer the mixture into a greased casserole dish and spread it evenly. For an irresistible golden crust, sprinkle extra shredded cheese or crushed pork rinds (for added crunch and low carb texture) on top.
Bake uncovered for about 25 to 30 minutes, or until the casserole is bubbly and the cheese on top is melted and lightly browned. Let it cool for a few minutes before serving to allow the flavors to meld and the casserole to set.

Avoiding a Watery Casserole
A common mistake when making casseroles—especially those loaded with veggies—is ending up with a watery or soggy final dish. Fortunately, you can easily avoid this issue with just a bit of prep. First, pre-cook your vegetables such as zucchini, spinach, or broccoli before adding them to the casserole. Sautéing them in a dry skillet or lightly steaming and draining helps release and remove excess moisture. If you’re using frozen vegetables, be sure to fully thaw and press out any water using a clean towel or paper towels. These extra steps might seem small, but they make a huge difference. You’ll get a thicker, creamier texture that holds together beautifully and doesn’t pool with liquid at the bottom—just what you want in a perfect low carb casserole.
Best Cheeses for Flavor and Texture
Choosing the right cheese blend can take your low carb chicken casserole from average to amazing. Each cheese plays a specific role in taste and texture. Sharp cheddar cheese brings depth and that familiar comforting flavor, while mozzarella contributes a smooth, creamy melt that ties everything together. Parmesan adds a rich, nutty finish that elevates the overall taste. When combined, these three cheeses create the ideal blend of sharpness, creaminess, and savory umami. For an extra crispy golden top, sprinkle a little more cheddar or parmesan before baking. This trio not only enhances flavor but also provides structure and richness without needing any flour or thickeners. It’s a cheesy, indulgent mix that fits beautifully into your low-carb lifestyle without feeling like you’re sacrificing anything.
How to Store and Reheat
Storing and reheating your easy low carb chicken casserole properly ensures that it remains just as satisfying on day two—or even day four. After baking, let the casserole cool completely before refrigerating. This prevents excess condensation, which could lead to sogginess. Transfer the cooled casserole into airtight containers and refrigerate for up to 4 days. For longer storage, freeze individual portions for up to 3 months. To reheat, use the microwave for speed, but cover it loosely with a lid or microwave-safe wrap to prevent drying out. For the best texture, reheat in the oven at 350°F (175°C) for about 15–20 minutes. This method helps restore the crispy top and creamy center, giving you that just-baked taste every time you reheat it.
Variations and Add-Ins
Spice It Up with Jalapeños or Hot Sauce
If you’re someone who loves bold, spicy flavors, this easy low carb chicken casserole is the perfect canvas to kick things up a notch. Stir finely chopped jalapeños, red chili flakes, or a dash of your favorite keto-friendly hot sauce directly into the creamy cheese base for a subtle heat that enhances—not overpowers—the dish. Want more of a punch? Layer a few jalapeño slices on top before baking for a pop of heat and visual flair. Whether you prefer smoky chipotle, tangy buffalo, or classic Tabasco, the options are endless and adjustable to your heat tolerance. This small customization gives the casserole a zesty twist, ideal for spice lovers looking to liven up their weekly meal routine without sacrificing their low-carb goals.
Add Extra Veggies for More Fiber
Adding more vegetables to your low carb chicken casserole not only boosts fiber content, it adds layers of flavor, nutrition, and color. Think beyond the basics—try adding mushrooms for an earthy note, zucchini for a fresh bite, or kale and spinach for added greens. Even chopped bell peppers can bring a subtle sweetness and vibrant contrast. These fiber-rich additions help support digestion, keep you feeling full longer, and contribute essential vitamins like A, C, and K. The best part? They blend seamlessly into the creamy, cheesy base while bulking up your dish in a healthy, delicious way. Sauté them beforehand to remove excess moisture, and you’ll ensure the casserole maintains its perfect texture while packing in even more health benefits.
Make It a One-Dish Meal
The beauty of a one-dish casserole lies in its simplicity and balance—everything you need for a nutritious meal, in one easy-to-clean pan. For the ideal low carb casserole, make sure it includes all your macronutrients: lean protein from chicken, healthy fats from cheese, cream, or olive oil, and fiber-rich veggies like spinach, zucchini, or cauliflower. This combination keeps you full and energized while supporting your keto or low-carb lifestyle. You won’t need to worry about side dishes or extra pots and pans—just bake and serve. It’s perfect for busy weeknights, family dinners, or anyone looking to simplify meal prep without skimping on flavor or nutrition. A well-built casserole like this truly makes eating healthy both delicious and effortless.
Can You Use Pasta in a Low Carb Casserole
Traditional Pasta vs. Alternatives
Traditional pasta, like ditalini pasta, is beloved for its texture but is high in carbohydrates. While it doesn’t fit strict keto or low carb diets, it can still be enjoyed in moderation by those on flexible low carb plans or non-keto diets. Knowing your carb limits helps you decide when and how to include it.
Low-Carb Pasta Options
If you want a pasta-like experience without the carbs, try alternatives such as shirataki noodles, hearts of palm pasta, or zucchini noodles (zoodles). These options are low in carbs and blend seamlessly into casseroles, maintaining the comforting pasta texture without spiking your carb intake.
When to Use Ditalini in Non-Keto Versions
For family meals or when carb flexibility is desired, you can make a “carb-flexible” casserole by adding a small amount of ditalini pasta. This version satisfies cravings for traditional pasta dishes while keeping portion sizes reasonable.
