Creating this Chile Relleno Casserole is a joyful process that invites you to engage all your senses. Here’s how to bring this dish to life in your kitchen:

1. **Prepare the Peppers:** Start by roasting the poblano peppers. You can do this over an open flame or under a broiler until the skin is blistered and charred. Once cooled, peel the skins off and remove the seeds.

2. **Layer the Casserole:** Preheat your oven to 375°F (190°C). In a greased baking dish, arrange the roasted peppers in a single layer. Top them with a mix of Monterey Jack and cheddar cheese, ensuring every bite is cheesy and delicious.

3. **Mix the Egg Mixture:** In a bowl, whisk together the eggs, milk, cumin, garlic powder, salt, and pepper. Pour this mixture over the peppers and cheese, letting it seep through the layers.

4. **Bake to Perfection:** Place the casserole in the oven and bake for about 30-35 minutes, or until the eggs are set and the top is golden brown.

5. **Add the Finishing Touches:** Once out of the oven, pour your favorite salsa over the top and sprinkle with fresh cilantro for a burst of color and flavor.

Each step is a reminder of the time spent in my grandmother’s kitchen, where patience and love were the main ingredients.
