Ingredients
- 2 lbs boneless, skinless chicken breast
- 3 cups broccoli florets (fresh or frozen)
- 8 oz sliced cremini or white mushrooms
- 8 oz full-fat cream cheese, room temperature
- ½ cup sour cream
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 3 cloves garlic, minced
- 1 small onion, diced
- 1 cup chicken broth
- 2 tbsp olive oil or butter
- Salt, pepper, and Italian seasoning to taste
- Optional: red pepper flakes for warmth
Step-by-step directions
Let’s get cooking! Preheat your oven to 375°F (190°C) and lightly grease your casserole dish with olive oil or butter to prepare for the delicious goodness to come.
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the chicken breasts with salt, pepper, and half the Italian seasoning. Cook for about 5-6 minutes on each side until they’re golden and cooked through. Once done, remove them from the skillet and let them rest for 5 minutes. Shred or dice the chicken into bite-sized pieces.
With the same skillet, add the remaining tablespoon of olive oil. Toss in your diced onion and minced garlic, sautéing until they soften and the kitchen fills with a lovely aroma, roughly 3 minutes. Next, add the sliced mushrooms and let them cook for about 5 minutes until they release their moisture and begin to brown. Stir in the broccoli florets and give them a quick 2-minute cook. Season everything with a pinch of salt and pepper.
Lower the heat to medium, then add in the cream cheese and sour cream, stirring continuously until the mixture becomes smooth and well-combined. Slowly pour in the chicken broth while whisking, creating a richly textured sauce. Return the shredded chicken to the skillet and gently mix everything together. Taste and feel free to adjust the seasoning with more salt, pepper, or Italian herbs as needed.
Pour this creamy chicken and veggie mixture into your prepared casserole dish, spreading it evenly. Now, it’s time for the magic: sprinkle shredded mozzarella and grated Parmesan cheese evenly over the top.
Bake for 20 to 25 minutes or until the cheese bubbles and turns golden brown. For those crispy edges we all crave, broil for the last 2 minutes, keeping a close eye to prevent burning.
Once it’s done, let the casserole sit for 5-10 minutes before serving—it’ll be worth the wait!

How to serve Creamy Low Carb Chicken Casserole?
Serving this delightful casserole is as simple as it gets. You can dish it out straight from the casserole dish, or if you’re feeling fancy, serve individual portions garnished with some freshly chopped parsley for a pop of color. Pair it with a fresh green salad or some roasted vegetables for a balanced meal. If you love a bit of heat, sprinkle some red pepper flakes on top before serving to elevate those flavors.
How to store Creamy Low Carb Chicken Casserole?
Storing this casserole is straightforward. Once cooled, cover it with plastic wrap or aluminum foil and pop it in the fridge for up to 4 days. If you want to keep it longer, you can freeze it for up to 3 months. Just ensure it’s in an airtight container or freezer-safe bag. When you’re ready to reheat, thaw it in the fridge overnight and heat it in the oven at 350°F (175°C) until warmed through—about 20-25 minutes should do the trick.
Tips for perfect Creamy Low Carb Chicken Casserole
Don’t Overcook the Chicken: Make sure you cook the chicken just until it’s done to keep it juicy. It’ll finish cooking in the oven, so you don’t want it to dry out.
Use Fresh Ingredients: If possible, use fresh broccoli and mushrooms for a crisper texture and more vibrant flavors.
Taste Test: Always taste your sauce before pouring it into the casserole. Adjust the seasonings according to your preference—this is your dish, after all!
Cover with Foil If Needed: If the cheese browns too quickly, tent the casserole with foil during baking to prevent burning while it cooks through.
Let It Rest: Let the casserole sit after baking for the recommended time. This helps the flavors meld and makes it easier to serve.
Variations
If you’re feeling adventurous, try these fun variations to shake things up a bit:
Vegetarian Version: Swap the chicken for a variety of vegetables, like zucchini, bell peppers, and cauliflower. You can also add chickpeas for protein.
Different Cheeses: Mix it up with different types of cheese—try cheddar or gouda for a unique flavor twist.
Herb Infusion: Add fresh herbs like thyme or rosemary for an aromatic kick that complements the creamy filling beautifully.
FAQs about Creamy Low Carb Chicken Casserole
Can I substitute the chicken?
Absolutely! You can use cooked shredded rotisserie chicken or even turkey if you have some on hand. Just make sure to add it toward the end of cooking the veggies to heat it through.
Can I make this casserole ahead of time?
Yes, you can prepare it the day before, cover it, and store it in the fridge. Just make sure to bring it to room temperature before baking, or extend the bake time.
Can I use different vegetables?
Definitely! Feel free to swap in your favorite vegetables like spinach, asparagus, or even some diced tomatoes. Just keep in mind that cooking times may vary slightly with different ingredients.
