• 1 tablespoon chili powder

• 1 teaspoon ground cumin
• 1 teaspoon dried oregano
• 0.25 teaspoons ground cayenne pepper
• 0.25 teaspoons ground paprika
• 0.25 teaspoons ground dried chipotle pepper

• 1 large onion , chopped
• 2 cans diced tomatoes with green chile peppers , 14.5 ounce

Instructions

1. 1

   Set the oven rack about 6 inches from the heat source and preheat the oven's broiler. Line a baking sheet with aluminum foil. Place poblano peppers cut-side down onto the prepared baking sheet.

2. 2

   Cook under the preheated broiler until poblano pepper skins have blackened and blistered, 5 to 8 minutes. Place blackened peppers into a bowl and cover tightly with plastic wrap. Allow peppers to steam as they cool, about 10 minutes.

3. 3

   Heat a large skillet over medium-high heat. Add beef, chili powder, garlic, cumin, oregano, cayenne pepper, paprika, chipotle pepper, salt, and black pepper. Cook and stir until beef is no longer pink, about 4 minutes. Add onion; cook until slightly softened, about 2 minutes. Add tomatoes with green chiles; cook until onions are translucent, about 5 minutes more. Let beef mixture cool.

4. 4

   Preheat the oven to 350 degrees F (175 degrees C). Spray a casserole dish with cooking spray.

5. 5

   Run water over the poblano peppers to remove skins and discard them; drain peppers on paper towels. Place a layer of peppers on the bottom of the prepared dish; place 1/3 of the beef mixture on top. Cover with 1 cup shredded Mexican cheese blend. Repeat layers twice more in the same order.

6. 6

   Bake, uncovered, in the preheated oven until golden brown on top, about 35 minutes.
