For Ground Beef Chile Relleno Casserole

Poblano Peppers – these are roasted first to bring out their smoky flavor, then peeled, seeded, and layered into the casserole.
Ground Beef – adds a hearty, savory filling and makes the casserole substantial enough for a main meal.
Onion and Garlic – these build the savory base of the beef mixture and add extra depth of flavor.
Cumin – gives the ground beef a warm, earthy flavor that works especially well with the roasted poblanos.
Pepper and Crushed Red Peppers – pepper seasons the beef, while the crushed red peppers add a little extra heat.
Monterey Jack Cheese – melts beautifully between the layers and gives the casserole a creamy, mild cheesiness.
Sharp Cheddar Cheese – brings a stronger cheesy flavor and creates the golden, bubbly topping.
Pepper Jack Cheese – adds another layer of creaminess along with a mild kick of heat.

For the Casserole Mixture

Half & Half – gives the egg mixture a rich, creamy texture as it bakes into the casserole.
All-Purpose Flour – helps the half & half and egg mixture set as the casserole cooks.
Eggs – bind the ingredients together and help create the soft, savory layer that holds everything in place.

Step-by-Step Instructions

Roast the Poblano Peppers

Preheat oven to 450° and line a baking sheet with foil and spray with a non stick spray.

Wash and dry peppers and place poblano peppers on baking sheet. Roast until peppers are charred and skin are blacken and bubbly, making sure to turn a few times. Approximately 20-25 minutes.

Once peppers have finished roasting, remove from oven and carefully place in a glass bowl. Cover with plastic wrap and let cool for about 15 minutes. When cool enough to handle, remove skins, slice in half lengthwise and rinse to remove seeds. Pat dry.

Prepare the Beef Filling

In a large frying pan, brown ground beef, onions and garlic. Add crushed red peppers, pepper and cumin. Once ground beef is thoroughly cooked, drain grease and return to pan.

Build the Casserole

In a 2 ½ quart baking dish, spray with a non stick spray. Place a layer of peppers in the bottom, then ¾ cup of Monterey Jack cheese, ½ of the ground beef mixture, ½ cup Pepper Jack cheese, and ½ cup of sharp cheddar cheese. Repeat layers ending with sharp cheddar cheese.

Add the Egg Mixture

In a small mixing bowl, whisk half & half, eggs and flour together. Pour on top of pepper mixture.

Bake

Bake uncovered at 350° for 30-35 minutes. Add remiaining ½ cup of cheddar cheese on top and pop back in the oven for 15 more minutes or so.

Serve

Once cheese has browned a bit, remove from oven and enjoy with your favorite side dishes like refried beans, rice, etc.

Expert Tips

Char the poblanos well. The peppers should have blackened, bubbly skin before you remove them from the oven. Turning them a few times helps them roast more evenly.

Give the peppers time to steam. Covering the roasted poblanos and letting them cool for about 15 minutes helps loosen the skins, making them easier to remove.

Dry the peppers before assembling. After rinsing away the seeds, pat the peppers dry so you don’t introduce unnecessary moisture into the casserole.

Drain the beef thoroughly. Once the ground beef is cooked, draining the grease before returning it to the pan helps keep the casserole from becoming too greasy.

Keep the layers even. Spread the peppers and beef mixture across the baking dish so the cheese and filling are distributed throughout the casserole.

Watch the final bake. The last 15 minutes are mainly for melting the remaining cheddar and getting the top nicely browned, so keep an eye on the cheese.

Recipe Variations

Make it spicier. Add more crushed red peppers to the beef mixture if you like a little extra heat.

Use a milder cheese combination. For a less spicy casserole, replace the Pepper Jack with additional Monterey Jack while keeping the rest of the recipe unchanged.

Add fresh toppings. Serve each portion with salsa, pico de gallo, avocado or fresh cilantro for a bright contrast to the rich casserole.

Make it a bigger meal. Pair the casserole with rice and refried beans for a filling dinner.

Storage & Reheating

Let leftover casserole cool before transferring it to an airtight container. Refrigerate for up to 3–4 days.
For individual portions, reheat in the microwave until warmed through. You can also reheat larger portions in the oven until hot in the center.
For the best texture, reheat only the amount you plan to eat rather than repeatedly warming the entire casserole.

Serving Suggestions

This casserole already has plenty of beef, roasted peppers and cheese, so simple sides work especially well.

Refried beans
Mexican-style rice
Fresh salsa
Pico de gallo
Guacamole
Avocado
Fresh cilantro
A crisp green salad
Warm tortillas

For an easy dinner, serve a generous square of the casserole alongside refried beans and rice. A spoonful of fresh salsa or guacamole on top adds a fresh contrast to the rich, cheesy layers.

Recipe FAQs

1. Can I roast the poblano peppers ahead of time?

Yes you can definitely roast the poblanos ahead of time. Once they have cooled, peel, seed, rinse, and pat them dry. Keep them covered in the refrigerator until you’re ready to assemble the casserole.

2. Do I have to peel the poblano peppers?

I recommend peeling them because the roasted skin can be tough and chewy. Letting the peppers steam in the covered bowl for about 15 minutes makes the skins much easier to remove.

3. How do I keep the casserole from getting watery?

Make sure you pat the roasted peppers dry after rinsing out the seeds. You also want to drain the ground beef well after cooking. Both steps will help keep excess moisture and grease out of the casserole.

4. Can I make this casserole ahead of time?

Yes you can prepare the casserole ahead of time and keep it covered in the refrigerator until you’re ready to bake it. Just make sure it stays refrigerated and bake according to the recipe instructions when you’re ready.

5. Can I freeze Ground Beef Chile Relleno Casserole?

Yes you can freeze it, although the texture of the peppers and egg mixture may be a little softer after thawing. For the best results, cool the baked casserole completely, wrap it tightly, and freeze. Thaw it in the refrigerator before reheating.
