How to Make Chicken Poblano Casserole

Preheat your oven to 350°F (175°C). This ensures the casserole bakes evenly, creating that golden, bubbly texture we all love.
Prepare the poblano peppers by placing them in a 9x13 casserole dish, drizzling with olive oil, and baking for 30-40 minutes until they become soft and fragrant.
Cool the roasted peppers. Once they’re cool enough to handle, remove the stems and seeds, then chop them coarsely to release their delicious smoky flavor into the casserole.
Mix the creamy sauce in a bowl by combining cream cheese, sour cream, mayonnaise, heavy cream, garlic powder, salt, and black pepper until smooth and luscious.
Layer the casserole by adding the chopped chicken and roasted poblano peppers into the dish. Spread them out evenly to ensure every bite is packed with flavor.
Spread the creamy mixture over the chicken and peppers, making sure it's evenly distributed. Then, sprinkle the top generously with shredded cheddar jack cheese.
Bake the casserole for an additional 25-30 minutes or until it’s hot and bubbly, with the cheese melting and browning slightly for that irresistible finish.

Optional: Garnish with fresh cilantro or green onions for a pop of color and flavor.
