Crafting Your Casserole: Step-by-Step Guide

Let’s build this beautiful, layered bake. It’s so easy!

Part 1: The Simple Sauce and Assembly

1. Make the Instant Enchilada Sauce: In a medium bowl, stir together the entire can of crushed tomatoes, the ground cumin, chipotle chile powder, and salt. That’s it! Your delicious, simple sauce is ready.
2. Start Layering: Coat a 7×11-inch (or similar 2-quart) casserole dish with cooking spray. Spoon about ½ cup of your tomato sauce into the bottom of the prepared dish and spread it around. Arrange about one-third of the tortilla wedges over the sauce. Top this with half of the black beans, half of the chopped chicken, and half of the sautéed peppers and onions. Pour 1 cup of the sauce over this layer and sprinkle with ½ cup of the cheese.

Part 2: The Final Layers

1. Repeat and Finish: Layer on half of the remaining tortillas. Top with the rest of the beans, chicken, and the pepper and onion mixture. Top this with another cup of the sauce and another ½ cup of cheese.
2. Final Touches: Arrange the last of the tortilla wedges on top, followed by the remaining sauce (about ⅓ cup). Sprinkle the last ½ cup of cheese all over the top. At this point, you can cover the dish with foil and refrigerate it for up to 3 days.

Part 3: The Bake

1. Bake to Bubbly Perfection: When you’re ready to eat, preheat your oven to 375°F. Bake the casserole, uncovered, for 35 to 40 minutes. It’s done when the sauce is hot and bubbling all around the edges and the cheese is beautifully melted.
2. Rest and Serve: Let the casserole rest for a few minutes before slicing and serving. This helps it to set up for cleaner portions. Enjoy hot!

Wise Tips for Casserole Success

• Meal Prep Components are Key: This recipe is designed to be a “dump and assemble” meal. Having your chicken already cooked (like using a rotisserie chicken) and your peppers and onions already sautéed is the secret to the super-fast 20-minute prep time.
• Don’t Skip the Sauce on the Bottom: That first layer of sauce in the bottom of the dish is crucial. It prevents the first layer of tortillas from sticking and ensures every part of the casserole is moist and flavorful.
• Control the Spice: The chipotle chile powder has a lovely smoky heat. Start with ½ teaspoon if you’re sensitive to spice, and use the full teaspoon if you like a little extra kick.

Frequently Asked Questions (FAQ) – Easy Chicken Enchilada Casserole

1. Can I use flour tortillas instead of corn?
   You can, but the texture will be much softer. Corn tortillas hold their shape a bit better in a layered casserole like this, giving it a more distinct texture that is closer to traditional enchiladas.
2. Can I make this vegetarian?
   Absolutely! Simply omit the chicken. To make it heartier, you can add an extra can of black or pinto beans, or a layer of roasted sweet potatoes.
3. Can I freeze this casserole?
   Yes, this is a great freezer meal! Assemble the casserole completely, but don’t bake it. Cover it tightly with a layer of plastic wrap and then a layer of heavy-duty foil. It can be frozen for up to 3 months. To bake, you can thaw it overnight in the refrigerator (and bake as directed) or bake from frozen, adding about 30-40 minutes to the total bake time.
4. What are some good toppings for this casserole?
   This casserole is fantastic served with a dollop of sour cream or Greek yogurt, some fresh chopped cilantro, diced avocado, or your favorite salsa.

Conclusion

This Easy Chicken Enchilada Casserole is the ultimate gift to your busy self. It’s a delicious, hearty, and satisfying meal that takes all the stress out of weeknight dinners.
