Instructions

1. Step 1: Preheat oven to 375°F. Roast 5 large poblano peppers on a baking sheet under the broiler, turning every 3 minutes until skins are charred and blistered, about 10 minutes. Cover with plastic wrap for 10 minutes, then peel and slice into 1/2-inch strips.
2. Step 2: In a large skillet, heat 2 tablespoons olive oil over medium heat. Add 1 medium diced onion and 3 minced garlic cloves, sauté for 5 minutes until softened and fragrant.
3. Step 3: Add 1 pound ground beef, 1 teaspoon cumin, 1 teaspoon chili powder, 1 teaspoon salt, and 1/2 teaspoon black pepper. Cook, breaking up beef, until browned and cooked through, about 8 minutes. Remove from heat.
4. Step 4: In a large bowl, whisk 6 large eggs with 1 cup whole milk until smooth.
5. Step 5: Grease a 9x13-inch baking dish. Layer half the poblano slices on the bottom, then spread half the beef mixture evenly, followed by 1 cup shredded Monterey Jack cheese. Repeat layers with remaining poblano slices, beef, and cheese.
6. Step 6: Pour the egg and milk mixture evenly over the layered ingredients. Gently press down to submerge.
7. Step 7: Bake uncovered for 40 minutes until set and golden on top. Let rest for 10 minutes before serving.
