Ingredients Overview

Ground Beef (1 lb): Provides a rich and savory base for the dish. I recommend using lean ground beef to keep the casserole from becoming too greasy.
Onion (1, diced): Adds sweetness and depth to the beef, making the filling more flavorful.
Garlic (2 cloves, minced): Infuses the dish with a warm, aromatic touch.
Diced Green Chiles (1 can): These mild green chiles add a slight kick and the authentic chile relleno flavor without overwhelming heat.
Shredded Cheddar Cheese (1 cup): Offers a sharp, tangy contrast to the spiced beef, balancing out the flavors.
Shredded Monterey Jack Cheese (1 cup): Adds creaminess and a mild buttery flavor that melts perfectly into the casserole.
Eggs (4): These form the base of the custard-like topping that sets the casserole and binds it together.
Milk (1 cup): Combined with eggs to create a rich, smooth custard that helps give the casserole its signature texture.
Salt & Pepper (to taste): Seasoning that enhances the natural flavors of the beef and cheese.

Step-by-Step Cooking Instructions

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Ensuring your oven is preheated allows for even cooking and the perfect set on your casserole.

2. Prepare the Beef Mixture

Cook the Ground Beef: In a large skillet over medium heat, add the ground beef, diced onion, and minced garlic. Sauté for 5-7 minutes, until the beef is browned and the onions are translucent. Make sure to drain the excess fat to avoid a greasy casserole.

Season and Add Chiles: Stir in the can of diced green chiles and season with salt and pepper to taste. Let the mixture cook for another 2 minutes, allowing the flavors to meld together. Set aside.

3. Whisk the Egg Mixture

In a separate bowl, whisk together the eggs and milk until smooth. This mixture will give the casserole its light, fluffy texture and help bind all the delicious ingredients together.

4. Layer the Casserole

In a lightly greased baking dish, spread half of the beef mixture evenly on the bottom. Follow this with half of the shredded cheddar and Monterey Jack cheeses. Repeat the layers with the remaining beef and cheese.

5. Pour the Egg Mixture

Carefully pour the egg and milk mixture over the layered beef and cheese. Make sure it’s evenly distributed so that the casserole sets properly.

6. Bake

Place the casserole in the preheated oven and bake for 30-35 minutes, or until the eggs are fully set and the cheese is melted and bubbly.

7. Serve

Once out of the oven, let the casserole sit for about 5 minutes before serving. This allows it to firm up slightly, making it easier to cut into neat portions. Serve hot and enjoy with your favorite sides like a fresh salad or Mexican rice.

Storage and Reheating Tips

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
Reheating: To reheat, simply place individual portions in the microwave for 1-2 minutes or until warmed through. If reheating a large portion, cover with foil and bake at 350°F for 10-15 minutes.
Freezing: This casserole also freezes well. Wrap tightly in plastic wrap and aluminum foil, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
