Beef Tortilla Casserole - vegetable oil

Method

• Adjust an oven rack to the middle position and preheat oven to 300° (not a typo).
• Heat the oil in a large Dutch oven over medium heat until shimmering.
• ADd the bell peppers and onion and cook until softened, about 5 minutes.
• Stir in the garlic, chili powder, and 1 teaspoon salt and cook until fragrant, about 30 seconds.
• Add the ground beef and cook, breaking it up with a wooden spoon, until no longer pink, about 5 minutes.
• Stir in the broth, chipotles, beans, and tomatoes and simmer until slightly thickened, about 10 minutes.
• Stir in 1/4 cup of the cilantro and the lime juice.
• Season with salt and pepper to taste.
• Meanwhile, spray both sides of the tortillas with vegetable oil spray and spread out over two baking sheets (some overlap is fine).
• Bake until the tortillas are soft and pliable, about 5 minutes.
• Remove the tortillas from the oven and increase oven temperature to 450°.
• Spread 1/3 of the beef mixture in a 9 x 13 inch baking dish.
• Layer 6 of the tortillas on top of the filling, overlapping as needed, then sprinkle with 3/4 cup of each cheese.
• Repeat to form a second layer.
• Spread the remaining filling in the baking dish.
• Cut the remaining 6 tortillas into quarters, then spread over the top.
• Sprinkle with the remaining 1/2 cup of each cheese.
• Bake until the cheese is golden brown and the casserole is bubbling, about 15 minutes.
• Let cool for 10 minutes.
• Sprinkle with the remaining 2 tablespoons cilantro before serving.
