Ingredients

• 16 ounces tomatillo salsa, jarred
• 4 boneless and skinless chicken breasts
• 1 teaspoon garlic powder
• 1/2 teaspoon kosher salt
• 1/4 teaspoon ground cumin
• 1/4 teaspoon ground black pepper
• 4 ounces mozzarella, shredded

Equipment

• 9×13-inch baking dish (or similar size)

• Instant-read thermometer (optional but helpful)

Prepping ahead

If you want to save time on a busy evening, assemble the casserole up to the point of baking and refrigerate it. Pull it out to warm at room temperature for 10 to 15 minutes before baking, then add a few extra minutes to the bake time as needed.

Flavor notes and swaps

The jarred tomatillo salsa is the star here; choose one you love. If you prefer more heat, pick a salsa labeled medium or hot, or stir in a pinch of crushed red pepper. For a creamier texture, fold in 2 to 4 ounces of cream cheese or sour cream before adding the shredded mozzarella. You can also swap mozzarella for Monterey Jack or a mild cheddar for a different cheese profile.

Step-by-step directions

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish so the casserole doesn’t stick.
2. Pat the chicken breasts dry with paper towels. Place them on a cutting board and, if desired, use a meat mallet or the flat side of a heavy pan to gently pound each breast to an even thickness for more even cooking. This step is optional but helps the chicken cook uniformly.
3. Place the chicken breasts in a mixing bowl or on a tray. Season them evenly with 1 teaspoon garlic powder, 1/2 teaspoon kosher salt, 1/4 teaspoon ground cumin, and 1/4 teaspoon ground black pepper. Rub the spices onto all sides so each piece is well coated.
4. Pour the 16 ounces of jarred tomatillo salsa into the prepared baking dish, using a spatula to spread it into an even layer across the bottom.
5. Arrange the seasoned chicken breasts directly on top of the salsa in the baking dish, spacing them slightly apart so heat can circulate during baking.
6. Spoon or pour any remaining salsa from the bowl over the chicken so each breast has a little extra sauce on top. This keeps the meat moist and infuses more tomatillo flavor.
7. Cover the baking dish with aluminum foil and place it in the preheated oven. Bake covered for 25 minutes; this initial covered bake gently cooks the chicken through without drying it out.
8. After 25 minutes, remove the dish from the oven and carefully take off the foil. Sprinkle the 4 ounces of shredded mozzarella evenly over the chicken and salsa.
9. Return the uncovered dish to the oven and bake for an additional 8 to 12 minutes, or until the cheese is melted and bubbling and the chicken reaches an internal temperature of 165°F (74°C) when checked with an instant-read thermometer.
10. Once cooked through and the cheese is melted, remove the casserole from the oven and let it rest for 5 minutes. Resting allows the juices to redistribute and makes serving easier.
11. Slice the chicken breasts if desired and serve family-style directly from the baking dish. Spoon extra salsa and melted cheese over each serving for maximum flavor.

Serving suggestions

• Serve over fluffy rice to soak up the salsa and melted cheese.
• Warm tortillas make excellent scoops for this casserole—turn it into a taco or enchilada-style plate.
• A crisp green salad or simple slaw provides contrast to the warm, saucy casserole.
• Top servings with chopped cilantro, sliced avocado, or a squeeze of lime if you like fresh, cooling accents.

Storage and reheating

Store leftovers covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave until warmed through, or reheat the whole dish in a 350°F (175°C) oven for 15–20 minutes, covering lightly with foil to prevent the cheese from over-browning. If the casserole looks dry when reheating, stir in a few tablespoons of water or extra salsa before warming.

Notes and tips for success

• Even-size chicken breasts cook more evenly. If your chicken breasts vary greatly in size, cut the larger ones in half or pound them to match the smaller pieces.
• Use a good-quality jarred tomatillo salsa—the flavor of the salsa determines most of the final taste, so choose one you enjoy straight from the jar.
• Monitoring the internal temperature of the chicken helps avoid overcooking. Remove the casserole from the oven once each breast reaches 165°F (74°C).
• Allow the casserole to rest briefly before serving so that it sets and is easier to portion.
