My Personal Experience

The first time I made this casserole, I was skeptical about achieving the same comforting flavors of a traditional Caprese dish while keeping it low-carb. But as the aroma of bubbling cheese and fresh basil filled my kitchen, I knew it was a winner. When I took that first cheesy bite, I was hooked. My family devoured it, and now it’s one of our favorite go-to meals. Pairing it with a light keto salad makes it feel like a complete Italian-inspired feast.

Required Equipment

• Large Baking Dish: A good-sized dish ensures even cooking and keeps all the cheesy goodness contained. I’ve found that the depth of the dish can make a difference—shallower dishes cook slightly faster.
• Mixing Bowls: For tossing the chicken and preparing the toppings. A medium bowl works well here, and I love ones that are easy to clean afterward.
• Cheese Grater: Freshly grated mozzarella melts so much better than pre-shredded. Using a grater gives that perfect gooey texture.
• Sharp Knife and Cutting Board: Slicing the tomatoes and chicken neatly makes for an even bake. A sturdy cutting board keeps the prep seamless.
• Aluminum Foil or Lid: Essential for covering the dish initially to lock in moisture during baking.

Ingredients & Substitutions

For the Casserole:

• Chicken Breasts (2 lbs): Boneless, skinless chicken cut into bite-sized pieces. If you prefer dark meat, thighs work just as well.
• Cherry Tomatoes (1 cup): Halved for a burst of sweetness. Substitute with diced Roma tomatoes if needed.
• Fresh Mozzarella (2 cups): Provides that gooey, melty texture. Shredded mozzarella is fine, but fresh takes it up a notch.
• Basil Leaves (1/4 cup): Fresh is best for that authentic Caprese flavor. Dried basil can work in a pinch.
• Olive Oil (2 tbsp): Enhances the flavors and prevents sticking. Avocado oil is a good alternative.
• Garlic (3 cloves, minced): Adds depth and aroma. Use garlic powder (1 tsp) if fresh isn’t available.
• Salt and Pepper (to taste): Essential for seasoning the dish.
• Parmesan Cheese (1/4 cup): Adds a nutty, savory layer to the casserole.
