Why you’ll love this recipe

This casserole blends the fresh, slightly tart flavor of salsa verde with tender chicken and melty mozzarella for a satisfying one-dish meal. It’s perfect for meal prep because it reheats beautifully—just portion and warm for lunches or a quick dinner later in the week. The ingredients are pantry-friendly and the method is forgiving, which makes it a great recipe to keep in your rotation.

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

Make-ahead & serving suggestions

You can assemble the casserole up to 24 hours ahead and keep it covered in the refrigerator; bake it the next day and add a few extra minutes to the finished cooking time if it’s chilled straight from the fridge. Leftovers are wonderful over rice, with a green salad, or stuffed into warm tortillas for a quick lunch. A squeeze of lime and a handful of chopped fresh cilantro on top brightens everything up.

Equipment you’ll need

9×13-inch baking dish (or similar casserole dish)
Mixing bowl
Measuring spoons
Sharp knife and cutting board
Oven mitts
Aluminum foil (optional)

Step-by-step instructions

Follow these steps to make the Salsa Verde Chicken Casserole. The directions have been rewritten into clear, sequential steps to ensure a smooth cooking experience while preserving the original ingredient amounts and order of operations.

Preheat your oven to 375°F (190°C). Position a rack in the center of the oven so the casserole will bake evenly.
Prepare the chicken breasts: pat the 4 boneless and skinless chicken breasts dry with paper towels. Place them on a cutting board and, if the breasts are thick, you may slice them horizontally to create even pieces so they cook uniformly. Leave them whole if they are already of even thickness.
Season the chicken: Sprinkle 1 teaspoon garlic powder, 1/2 teaspoon kosher salt, 1/4 teaspoon ground cumin, and 1/4 teaspoon ground black pepper evenly over both sides of the chicken breasts. Rub the spices into the meat so each piece is seasoned.
Arrange the chicken in the baking dish: Place the seasoned chicken breasts in a single layer in a 9×13-inch (or similar) baking dish. Make sure they sit flat and don’t significantly overlap so the salsa can coat each piece.
Pour the salsa verde over the chicken: Open the 16 ounces jar of tomatillo salsa and pour it evenly over the chicken breasts. Use a spoon or spatula to spread the salsa so each piece is covered with a thin layer.
Cover and bake the chicken: Cover the baking dish tightly with aluminum foil or an oven-safe lid. Bake for 25 minutes at 375°F (190°C). This initial covered time lets the chicken cook gently and absorb the salsa verde flavors.
Check for doneness: After 25 minutes, carefully remove the foil. Use an instant-read thermometer to check the thickest part of a chicken breast; it should register 165°F (74°C). If the chicken hasn’t reached 165°F yet, re-cover and return the dish to the oven for an additional 5 to 10 minutes, then check again.
Top with cheese: Once the chicken has reached the safe internal temperature, sprinkle 4 ounces shredded mozzarella evenly over the tops of the chicken breasts and the salsa-covered surface.
Bake uncovered to melt the cheese: Return the casserole to the oven, uncovered, and bake for 5 to 8 more minutes, or until the mozzarella is fully melted and bubbly and just beginning to turn golden at the edges.
Rest before serving: Remove the casserole from the oven and let it rest for 5 minutes. This short resting time lets juices settle and makes the dish easier to serve.
Serve and garnish: Serve each chicken breast with some of the salsa verde from the casserole dish spooned over the top. Optional fresh garnishes like chopped cilantro, sliced green onions, or a lime wedge enhance the bright flavors, but the casserole is delicious as written.

Troubleshooting & tips

If your chicken breasts vary greatly in thickness, pound them to a uniform thickness or slice thicker breasts in half horizontally so everything cooks at the same rate.
Use an instant-read thermometer to avoid overcooking; chicken is done at 165°F (74°C).
If you prefer a saucier casserole, stir an extra 1/4 to 1/2 cup of salsa into the pan before adding cheese.
For a crispier cheese top, broil the casserole for 1–2 minutes at the end of baking—watch it closely so the cheese does not burn.

Flavor variations

Want to switch things up? Try these simple variations while keeping the core recipe intact:

Add a can of drained corn for sweetness and texture.
Stir in a cup of cooked rice or quinoa under the chicken before baking for a one-pan meal.
Swap mozzarella for a sharper melting cheese like fontina or a Mexican blend for more depth.
For a smoky note, add 1/4 teaspoon smoked paprika to the chicken seasoning.

Nutritional note

This casserole balances lean protein with a modest amount of cheese and a tomato-tomatillo-based sauce. Sodium will vary depending on the salsa brand and whether you use reduced-sodium options. To control sodium, choose a low-sodium salsa and adjust the added kosher salt as desired.

Storage and reheating

Refrigerate leftovers in an airtight container for up to 3 days. To reheat, place individual portions in a microwave-safe dish and microwave on medium power until warmed through, or reheat in a 350°F (175°C) oven, covered, for about 15–20 minutes or until hot. If the casserole has been chilled, allow it to come closer to room temperature before baking to reduce reheating time.

Final thoughts

Salsa Verde Chicken Casserole is an uncomplicated, crowd-pleasing dish that brings bright flavors to the dinner table with minimal effort. The jarred salsa verde speeds things up, the spice mix is pantry-simple, and the melted mozzarella ties everything together. Whether you’re feeding a family or prepping dinners for the week, this casserole is a dependable, tasty option that cooks will reach for again and again.
