Ingredients

For the jalapeno popper filling:

• 2 cups cooked, shredded chicken (rotisserie chicken works great)
• 8 oz cream cheese, softened
• 1/2 cup sour cream
• 1 cup shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
• 4 oz diced jalapenos (fresh or jarred)
• 1/2 cup finely chopped onion (optional)
• 1 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 cup chopped fresh cilantro (optional)

For the cornbread topping:

• 1 box (8.5 oz) cornbread mix (or homemade recipe)
• 1 egg
• 1/3 cup milk
• 1 cup frozen or canned corn, drained
• 1/4 cup melted butter
• 1/2 cup shredded cheddar cheese (for topping)

Optional Substitutions

• Cream cheese: Use Neufchatel or low-fat cream cheese for fewer calories, but the filling will be slightly less creamy.
• Sour cream: Greek yogurt works well for a tangier, higher-protein option.
• Cheddar cheese: Swap with Colby Jack, pepper jack (for extra heat), or a Mexican blend.
• Jalapenos: For milder flavor, use pickled jalapenos or reduce the amount. For more heat, add fresh minced serranos.
• Chicken: Use ground beef, turkey, or even canned tuna for a change.
• Cornbread mix: Make from scratch with cornmeal, flour, baking powder, sugar, egg, and milk.
• Gluten-free: Use gluten-free cornbread mix and check that all other ingredients are certified gluten-free.
• Dairy-free: Use vegan cream cheese, dairy-free sour cream, and vegan cheese shreds.

Instructions

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or spray with nonstick cooking spray.
2. In a large bowl, combine the softened cream cheese and sour cream. Mix until smooth and creamy.
3. Add the shredded chicken, 1/2 cup cheddar cheese, 1/2 cup Monterey Jack cheese, diced jalapenos, onion (if using), garlic powder, salt, pepper, and cilantro (if using). Stir everything together until well combined.
4. Spread the chicken mixture evenly into the prepared baking dish.
5. In a separate bowl, prepare the cornbread topping: whisk together the cornbread mix, egg, and milk until just combined. Fold in the drained corn and melted butter.
6. Spoon the cornbread batter over the chicken filling, spreading it gently to cover the top evenly. It is okay if some filling peeks through.
7. Sprinkle the remaining 1/2 cup shredded cheddar cheese and the remaining 1/2 cup Monterey Jack cheese over the cornbread batter.
8. Bake for 25-30 minutes, until the cornbread is golden brown and a toothpick inserted into the cornbread comes out clean. The edges of the casserole will be bubbly.
9. Let the casserole rest for 5-10 minutes before serving. This helps it set and makes slicing easier.
10. Garnish with extra chopped cilantro, sliced jalapenos, or a dollop of sour cream if desired. Serve warm.

Pro Tips

• Soften cream cheese properly: Let cream cheese sit at room temperature for 30 minutes before mixing. This prevents lumps in the filling.
• Use rotisserie chicken: It saves time and adds great flavor. Shred it while it is still warm for easier handling.
• Don't overmix the cornbread: Overmixing makes the topping dense and tough. Stir until just combined.
• Fresh jalapenos: For more intense heat, use fresh jalapenos and include the seeds. For milder, use jarred jalapenos.
• Add a crispy topping: For extra crunch, mix crushed corn chips or panko breadcrumbs with melted butter and sprinkle on top before baking.
• Check doneness: The cornbread should be golden brown and a toothpick inserted in the center should come out clean. If the top browns too fast, cover loosely with foil.
• Let it rest: Allowing the casserole to rest after baking ensures cleaner slices and prevents the filling from being runny.

Variations and Substitutions

• Buffalo chicken style: Add 1/2 cup buffalo sauce and 1/2 cup crumbled blue cheese to the filling. Omit jalapenos if desired.
• Southwest casserole: Add 1 can drained black beans, 1 cup corn, and 1 teaspoon cumin to the filling. Use pepper jack cheese.
• Vegetarian version: Replace chicken with 2 cans drained black beans and 1 cup sautéed mushrooms. Add extra veggies like bell peppers and zucchini.
• Low-carb: Use a keto cornbread mix made with almond flour and reduce the corn. The filling is already low-carb friendly.
• Spicy Italian: Add 1/2 cup chopped pepperoni and 1 teaspoon Italian seasoning to the filling. Use provolone or mozzarella.
• Chicken taco: Mix in 1 packet taco seasoning, 1 can diced tomatoes with green chiles, and top with crushed tortilla chips.
• Make it a meal: Serve with a side of sour cream, fresh salsa, and avocado slices for a complete dinner.
• Cheesy cornbread topping: Stir 1/2 cup shredded cheese into the cornbread batter before spreading for extra cheesy topping.

Storage and Reheating

Fridge

Store leftovers in an airtight container in the refrigerator for up to 4 days. The casserole may absorb some moisture, so reheat to restore texture.

Freezer

To freeze, let the casserole cool completely. Wrap tightly in plastic wrap, then foil, or place in a freezer-safe container. Freeze for up to 3 months. To serve, thaw overnight in the refrigerator before reheating.

Reheating

For best results, reheat individual portions in the microwave for 1-2 minutes, or reheat the whole casserole in a 350°F oven covered with foil for about 20 minutes until warmed through. The cornbread topping will crisp up nicely in the oven.

FAQ

Can I use raw chicken instead of cooked? Yes but you need to cook it first. Dice raw chicken into small pieces, sauté in a skillet with oil until cooked through, then proceed with the recipe. Do not add raw chicken to the casserole.

How can I make this less spicy? Use jarred jalapenos (which are milder) and remove the seeds. You can also reduce the amount or skip them entirely. The cornbread and cream cheese help mellow the heat.

Can I make this casserole ahead of time? Yes. Assemble the casserole completely, cover, and refrigerate for up to 24 hours before baking. Add about 10-15 minutes to the baking time since you are starting cold.

Can I use homemade cornbread instead of mix? Absolutely. Use your favorite recipe or a simple combination of 1 cup cornmeal, 1 cup all-purpose flour, 1/3 cup sugar, 1 tablespoon baking powder, 1/2 teaspoon salt, 1 cup milk, 1/3 cup melted butter, and 1 egg. Mix and use as topping.

How do I know when the casserole is done? The cornbread should be golden brown and a toothpick inserted into the cornbread topping should come out clean. The filling will be hot and bubbly around the edges.

Can I add vegetables to the filling? Yes. Diced bell peppers, sautéed mushrooms, or even spinach work well. Just be sure to drain any excess moisture so the filling doesn't become watery.

What should I serve with this casserole? A simple side salad, roasted vegetables, or steamed rice make great accompaniments. It is also hearty enough to stand alone.

Is this recipe gluten-free? Not as written, but you can easily make it gluten-free by using a gluten-free cornbread mix and checking that all other ingredients are certified gluten-free.
