Step-by-Step Instructions
Preparing the Chicken and Pesto Mixture
To start, preheat your oven to 375°F (190°C). This step warms the oven so the casserole cooks evenly. In a large bowl, mix 2 cups of shredded chicken, 1 cup of heavy cream, and 1 cup of basil pesto. Add 2 cloves of minced garlic for extra flavor. Stir well until the chicken is fully coated in the creamy pesto mixture. This gives the dish its rich taste.
Adding Vegetables and Seasoning
Next, fold in 1 cup of diced zucchini and 1 cup of halved cherry tomatoes. Make sure they spread throughout the mix. This adds color and nutrients. Season the mixture with 1 teaspoon of Italian seasoning, salt, and pepper to taste. Mix it all together until combined. This step enhances the flavors and makes the dish more tasty.
Baking Instructions and Tips
Transfer your chicken and vegetable mix into a greased 9x13-inch baking dish. Spread it out evenly. Then, sprinkle 1 cup of shredded mozzarella cheese and ½ cup of grated Parmesan cheese on top. Cover with aluminum foil and bake for 25 minutes. After that, remove the foil and bake for another 10-15 minutes. Wait until the cheese is bubbly and golden brown. Once it's done, let it cool for a few minutes before slicing. For a nice touch, add fresh basil leaves on top before serving.
Tips & Tricks
How to Ensure Perfectly Cooked Chicken
To ensure your chicken is tender, start with cooked chicken. I love using rotisserie chicken for ease. Shred the chicken into small pieces. This allows the flavors to mix well. If you cook chicken yourself, poach it. Boil the chicken in seasoned water until fully cooked. This method keeps it juicy. Always check the internal temperature. It should reach 165°F (75°C).
Best Cheese Options for Topping
Using the right cheese makes a huge difference. I recommend mozzarella for its stretchiness. It melts beautifully and adds a great flavor. Parmesan is also key. It adds a nice sharpness and crunch when baked. You can mix them for extra flavor. Try adding a bit of cheddar for a twist. Just remember, keep it low-carb!
Cooking Techniques for a Creamy Texture
To achieve a creamy texture, use heavy cream. This gives your casserole richness. Mixing it with the pesto and chicken makes it smooth. Stir well to coat everything evenly. For extra creaminess, consider adding cream cheese. Blend it in before baking. Cover the dish with foil for the first part of baking. This traps steam, helping everything cook evenly. Remove the foil later to let the cheese brown.
Pro Tips
- Use Rotisserie Chicken: For a quicker prep time, consider using store-bought rotisserie chicken instead of cooking your own. It saves time and adds great flavor.
- Customize Your Veggies: Feel free to swap out zucchini and cherry tomatoes for other low-carb vegetables like bell peppers or spinach based on your preference.
- Cheese Variations: Experiment with different cheeses! Try adding goat cheese or cheddar for a unique flavor twist.
- Make Ahead: This casserole can be prepared ahead of time. Assemble it and store it in the fridge for up to 24 hours before baking for an easy weeknight dinner.

Variations
Vegetarian Option for Keto Pesto Casserole
You can easily make this casserole vegetarian. Just swap the chicken for extra veggies. Consider using mushrooms, bell peppers, or spinach. These options add flavor and color to your dish. The creamy pesto will still taste great with these veggies. This change keeps it keto-friendly and delicious.
Low-Carb Fun Add-Ins and Substitutions
You can also add fun ingredients to this dish. Try adding artichokes or olives for a tangy twist. For a crunch, consider adding nuts like pine nuts or walnuts. They add texture and nutrients. If you want a creamier dish, add more heavy cream or cheese. Keep it low-carb and flavorful by mixing in your favorite ingredients.
Using Different Pesto Flavors
Pesto doesn’t have to be just basil. You can use other types of pesto to change the taste. Try sun-dried tomato pesto for a rich flavor. If you like spice, use a spicy pesto with jalapeños. Each type of pesto adds a new layer of taste. This way, you can enjoy a new dish every time you make it.
