Ingredients
- For the Pesto Sauce:
- 2 cups fresh basil leaves, packed
- 1/2 cup extra virgin olive oil
- 1/3 cup grated Parmesan cheese
- 1/4 cup pine nuts (toasted for added depth)
- 3 garlic cloves, minced
- Salt, to taste
- Freshly ground black pepper, to taste
- 1 tablespoon lemon juice (optional, brightens flavor)
- For the Casserole:
- 4 cups cooked shredded chicken breast (skinless, boneless)
- 2 cups fresh spinach, roughly chopped
- 1 cup mozzarella cheese, shredded
- 1/2 cup heavy cream
- 1/2 cup sun-dried tomatoes, chopped (oil-packed for richness)
- 1/4 cup grated Parmesan cheese (for topping)
- Salt and pepper, to taste

Instructions
- Prepare the pesto sauce: In a food processor, combine basil leaves, toasted pine nuts, minced garlic, grated Parmesan, and lemon juice. Pulse while slowly drizzling in olive oil until a smooth, thick sauce forms. Season with salt and freshly ground black pepper to taste. Set aside.
- Preheat your oven: Set to 375°F (190°C) and grease a 9×13-inch casserole dish with olive oil or cooking spray to prevent sticking.
- Mix the casserole ingredients: In a large bowl, toss shredded chicken, chopped spinach, sun-dried tomatoes, heavy cream, and about 3/4 cup of the pesto sauce. Season lightly with salt and pepper, remembering the Parmesan and pesto already add saltiness.
- Assemble the casserole: Transfer the mixture evenly into the prepared casserole dish. Sprinkle shredded mozzarella and grated Parmesan evenly on top for that golden, bubbly crust.
- Bake to perfection: place the dish in the oven and bake uncovered for 30-35 minutes or until the cheese is melted, bubbly, and slightly golden on the edges. For extra browning, broil for the last 2 minutes, watching carefully to avoid burning.
- Rest before serving: Let the casserole sit for 5-10 minutes once out of the oven to thicken and settle the flavors.
Tips for Success
- Customize your pesto: Swap pine nuts for walnuts or almonds for a different nutty aroma without losing richness.
- brighten up the dish: A splash of fresh lemon juice or zest in the pesto intensifies freshness and balances creaminess.
- Make ahead and freeze: Prepare the casserole up to step 4, cover tightly, and freeze. Thaw overnight in the fridge before baking.
- Ensure even cooking: Use shredded or diced chicken evenly dispersed to soak up all the pesto goodness.
- Leafy greens: wilted spinach adds moisture and nutrition,but kale or swiss chard make excellent substitutions for variety.

Unlike conventional casseroles that rely on starchy fillers, this dish uses low-carb ingredients, making it perfect for anyone seeking a hearty yet keto-friendly meal.
