A creamy, cheesy, and incredibly easy Caprese Chicken Casserole featuring shredded chicken, fresh mozzarella, cherry tomatoes, and basil pesto – all baked together into a golden, bubbly dish.

Ingredients

Scale
  • 1 pound cooked chicken breasts, shredded (rotisserie chicken works great)
  • 1 cup cherry tomatoes, halved
  • 8 oz fresh mozzarella, chopped (or mozzarella balls)
  • 1/4 cup basil pesto
  • 1 cup mayonnaise
  • 3/4 cup shredded Parmesan cheese, divided
  • Salt and pepper, to taste

Instructions

  1. Preheat your oven to 400 degrees F (200 degrees C). Grease a 2-quart baking dish with cooking spray or a light brush of olive oil.
  2. In a large bowl, combine the shredded chicken, pesto, mayonnaise, half the Parmesan, salt, and pepper. Stir until the mixture looks thick, creamy, and uniform with no dry patches of chicken visible.
  3. Spread the chicken mixture evenly into the prepared baking dish and smooth into a flat, even layer with the back of a spoon.
  4. Scatter the halved cherry tomatoes and chopped mozzarella evenly over the top. Sprinkle the remaining Parmesan over everything.
  5. Bake for 20 to 22 minutes until the top is golden and the edges are visibly bubbling. Do not overbake.
  6. Let rest for 3 to 5 minutes before scooping and serving.

Notes

  • Rotisserie chicken is a great time-saving option and works perfectly shredded into this recipe.
  • Use fresh mozzarella for the best melt and flavor – it makes a noticeable difference over shredded.
  • Do not overbake – pull it out as soon as the top is golden and bubbly to keep the filling creamy.
  • If the casserole comes out watery, make sure to pat the shredded chicken dry before mixing and use halved cherry tomatoes rather than large sliced tomatoes.
