Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 35-45 minutes
• Total Time: 50-60 minutes
• Servings: 9
• Yield: 1 casserole
• Dietary Type: Gluten-Free (naturally)

Ingredients

• 1 (27 ounce) can green chilies, whole
• 3 cups Monterey Jack cheese, grated
• 5 large eggs
• 2 cups whole milk
• Salt and pepper, to taste
• ½ teaspoon paprika
• ¼ teaspoon cayenne pepper

Equipment Needed

• 9 x 13-inch baking dish
• Large mixing bowl
• Whisk
• Larger baking dish or rimmed baking sheet

Instructions

1. Begin by preheating your oven to 325 degrees Fahrenheit (160 degrees Celsius). This lower temperature ensures the casserole cooks evenly and prevents the eggs from becoming rubbery.

2. In a large mixing bowl, whisk together the eggs and whole milk until well combined. Season generously with salt and pepper to taste. Don’t be shy – the seasoning is important for bringing out the flavors. Next, add the paprika and cayenne pepper. The paprika adds a subtle sweetness and smoky note, while the cayenne provides a gentle kick. Adjust the amount of cayenne to your preference – if you like things spicier, feel free to add a bit more.

3. Open the can of green chilies and carefully cut each chili in half lengthwise. This makes them easier to layer in the baking dish.

4. Lightly grease a 9 x 13-inch baking dish to prevent sticking. Then, arrange a single layer of the halved green chilies on the bottom of the dish, covering the entire surface.

5. Sprinkle half of the grated Monterey Jack cheese evenly over the layer of chilies. Make sure to distribute the cheese so that every chili is generously covered.

6. Repeat the layering process: add another layer of the remaining green chilies, followed by the remaining grated Monterey Jack cheese.

7. Pour the egg mixture evenly over the top of the layered chilies and cheese. Gently press down with a spatula to ensure the egg mixture seeps into all the crevices and covers the entire casserole.

8. Place the baking dish containing the casserole into a larger baking dish or a rimmed baking sheet. This is to create a water bath, which helps the casserole cook gently and evenly. Pour about ½ inch of water into the larger baking dish. The water should come about halfway up the sides of the casserole dish.

9. Bake in the preheated oven for 35 to 45 minutes, or until the casserole is completely set. To check for doneness, gently shake the baking dish. The casserole should be firm and not wobbly in the center. You can also insert a knife into the center; if it comes out clean, the casserole is done. If the top is browning too quickly, you can loosely tent it with aluminum foil.

10. Remove the casserole from the oven and let it cool for a few minutes before cutting it into squares.

11. Serve warm, optionally with warm corn tortillas, your favorite salsa, sour cream, or guacamole.

Expert Tips & Tricks

• Cheese Choice: While Monterey Jack is classic, feel free to experiment with other cheeses like cheddar, Oaxaca, or pepper jack for a different flavor profile. A combination of cheeses can also be delicious.
• Chili Heat: Control the heat level by using mild, medium, or hot green chilies. You can also add a pinch of red pepper flakes to the egg mixture for an extra kick.
• Prevent Soggy Casserole: Make sure to drain the green chilies well before layering them in the baking dish. This will help prevent the casserole from becoming too watery.
• Make-Ahead Option: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Add about 10-15 minutes to the baking time if baking from cold.
• Browning the Top: If you want a more golden-brown top, broil the casserole for the last few minutes of cooking, watching carefully to prevent burning.
• Spice it up! Add a can of drained and rinsed black beans, some cooked chorizo, or some leftover shredded chicken for a heartier meal.

Serving & Storage Suggestions

Serve the Lazy Chiles Rellenos Casserole warm, straight from the oven. It’s delicious on its own, but even better when accompanied by warm corn tortillas, your favorite salsa, sour cream, guacamole, or a simple side salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until warmed through. Freezing is not recommended, as the texture of the eggs may change upon thawing.
