Store-bought options were loaded with hidden sugars, and eating out meant derailing my goals. That’s when I started experimenting in my kitchen, turning classic comfort foods into low-carb versions. This creamy low carb chicken casserole became my staple—it’s rich, satisfying, and guilt-free, proving you don’t need pasta or rice for that cozy feeling.

Keto Chicken and Vegetable Casserole – Creamy & Cheesy
Why This Casserole Fits Low-Carb and Keto Lifestyles
This recipe shines for anyone on a low-carb or keto diet because it swaps high-carb fillers for nutrient-dense ingredients. The creaminess comes from heavy cream and cheese, delivering that indulgent texture without spiking your blood sugar. Chicken provides lean protein to keep you full, while veggies add fiber and volume. Best of all, it’s meal-prep friendly—make a batch on Sunday, and you’ve got lunches sorted for the week. No more midday slumps or takeout temptations.
Ingredients for Creamy Low Carb Chicken Casserole
Here’s what you’ll need for 6 servings. I keep it simple with pantry staples and fresh basics.
- Boneless, skinless chicken breasts (1.5 lbs): Easy to cook and shred; they’re a lean protein base that absorbs flavors well.
- Heavy cream (1 cup): Creates the ultra-creamy sauce without carbs; opt for full-fat for keto compliance.
- Cream cheese (8 oz): Softens into a thick, tangy binder that holds everything together.
- Shredded cheddar cheese (1.5 cups): Melts beautifully for that gooey top; sharp variety adds depth.
- Broccoli florets (2 cups): Low-carb veggie for crunch and nutrients; fresh or frozen works.
- Diced onion (1 medium): Builds savory base flavors without overpowering.
- Minced garlic (3 cloves): Essential for aroma and taste; fresh is best.
- Butter (2 tbsp): For sautéing; adds richness.
- Paprika, salt, and pepper (to taste): Simple seasonings to enhance without complexity.

Step-by-Step Instructions: Let’s Cook Together
Think of this as me standing next to you in the kitchen, walking you through it. Preheat your oven to 375°F (190°C).
- Start by prepping the chicken. Cube the breasts into bite-sized pieces. I always sear them first in my quality non-stick skillet—it’s a game-changer for even browning without sticking, and I’ve had mine for years, saving me time on cleanup.
- Heat 1 tbsp butter in the skillet over medium heat. Add the chicken, season with salt, pepper, and paprika. Cook for 5-7 minutes until golden but not fully done—it’ll finish in the oven.

- In the same skillet, melt the remaining butter. Toss in the onion and garlic, sautéing for 3 minutes until soft. This builds that flavorful foundation.
- Lower the heat and stir in the heavy cream and cream cheese. Whisk until smooth—here’s where my high-powered blender comes in handy if lumps form; I pulse it for ultra-smooth sauces every time, and it’s worth the investment for consistent results in all my creamy recipes.
- Add the broccoli and half the cheddar. Mix well, then fold in the chicken.
- Transfer everything to a premium ceramic casserole dish. I swear by my cast-iron one for even heat distribution—it prevents hot spots and makes the dish look restaurant-quality when serving. Top with remaining cheese.
- Bake for 25-30 minutes until bubbly and golden. Use a digital meat thermometer to check the chicken hits 165°F internally; mine ensures perfect doneness without guesswork, avoiding dry meat.

Pro Tips for the Best Results
To avoid dryness, don’t overcook the chicken in the skillet—keep it slightly pink inside. For flavor, taste the sauce before baking and adjust seasonings; a dash of paprika can fix blandness. If it seems too thick, thin with a splash of cream. These tweaks come from my trial-and-error days.
Storage, Reheating, and Freezing Tips
Store leftovers in airtight containers in the fridge for up to 4 days. Reheat in the microwave at 50% power to prevent separating, or oven at 350°F for 10 minutes. For freezing, portion before baking, wrap tightly, and freeze for 3 months. Thaw overnight and bake as directed—it’s my secret for busy weeks.
