1. Baked Beef Chiles Rellenos Casserole Recipe (Yield: 8 Servings)
Ingredients
- 16 ounces shredded Cheddar cheese
- 4 large eggs
- 1½ cups milk
- ½ cup all-purpose flour
- Salt and black pepper, to taste
- 1 (7-ounce) can Ortega whole green chiles
- 1 pound ground beef, cooked, browned, and crumbled
Instructions
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or a thin coating of butter to prevent sticking.
Cook the ground beef in a large skillet over medium-high heat until it is completely browned, breaking it apart with a wooden spoon as it cooks. Drain any excess grease thoroughly and season lightly with salt and black pepper. Allow the beef to cool slightly while preparing the remaining ingredients.
Open the can of whole green chiles and carefully drain away the liquid. Lay the chiles on several layers of paper towels and gently pat them dry. Removing excess moisture helps the casserole bake evenly without becoming watery.
Spread half of the shredded Cheddar cheese evenly across the bottom of the prepared baking dish.
Arrange the whole green chiles over the cheese layer. If necessary, gently flatten the chiles so they cover most of the surface.
Evenly distribute the cooked ground beef over the chiles, spreading it into an even layer without pressing it down too firmly.
Top the beef with the remaining shredded Cheddar cheese, making sure it reaches the edges of the baking dish for even melting.
In a large mixing bowl, whisk together the eggs until smooth. Add the milk, flour, salt, and black pepper. Continue whisking until the batter is completely smooth and free of lumps. The consistency should resemble a thin pancake batter.
Slowly pour the egg mixture evenly over the layered casserole, allowing it to settle naturally between the beef, cheese, and chiles.
Place the casserole into the preheated oven and bake uncovered for 40 to 45 minutes. The casserole is finished when the center is fully set, the edges are lightly browned, and the top has puffed slightly.
To check for doneness, insert a knife into the center. It should come out clean without liquid batter remaining.
Remove the casserole from the oven and let it rest for about 10 minutes before slicing. Resting allows the egg layer to firm up, making it easier to serve clean portions.
Serve warm with salsa, sour cream, sliced avocado, chopped cilantro, or your favorite hot sauce. This casserole also pairs beautifully with Spanish rice, black beans, roasted vegetables, or tortilla chips.

2. Tips for Perfect Baked Beef Chiles Rellenos Casserole
Drain the cooked ground beef thoroughly before assembling the casserole. Excess grease can make the finished dish heavy and oily.
Pat the canned green chiles dry before layering them into the baking dish. Removing extra moisture helps the casserole maintain a firm texture.
Freshly shredded Cheddar cheese melts more smoothly than pre-shredded cheese, which often contains anti-caking agents.
Whisk the egg batter thoroughly until completely smooth. A lump-free batter creates a light, even texture throughout the casserole.
Pour the batter slowly over the layers instead of all at once. This allows it to spread evenly into every corner of the dish.
Avoid overbaking. Remove the casserole once the center is set to keep the egg layer soft and tender instead of rubbery.
Allow the casserole to rest before slicing. This simple step helps the layers hold together beautifully when served.
For extra flavor, garnish each serving with chopped cilantro, diced tomatoes, sliced jalapeños, green onions, or a spoonful of fresh salsa.
3. Frequently Asked Questions
Can I use fresh roasted poblano peppers instead of canned green chiles?
Yes. Roasted, peeled poblano peppers are an excellent substitute and provide an even more authentic chile relleno flavor.
Can I prepare this casserole ahead of time?
Absolutely. Assemble the casserole up to one day in advance, cover it tightly, and refrigerate. Bake it just before serving, adding a few extra minutes if baking directly from the refrigerator.
Can I freeze leftovers?
Yes. Allow the casserole to cool completely before wrapping individual portions or the entire casserole tightly. Freeze for up to three months and thaw overnight in the refrigerator before reheating.
What side dishes pair well with this casserole?
Mexican rice, cilantro lime rice, refried beans, black beans, corn salad, roasted vegetables, tortilla chips, or a fresh green salad all make excellent accompaniments.
Can I use a different type of cheese?
Certainly. Monterey Jack, Pepper Jack, Colby Jack, or a Mexican cheese blend all melt beautifully and can be used alone or combined with Cheddar for additional flavor.
