Ingredient Notes

Poblano Peppers

Poblano peppers are the star of this casserole. They have a mild-to-medium heat level and develop a wonderfully smoky, slightly sweet flavor when roasted.

If you prefer less heat, remove all the seeds and inner membranes after roasting.

Ground Beef

Lean ground beef works well because it provides plenty of savory flavor without making the casserole excessively greasy.

You can substitute ground turkey or ground chicken if preferred.

Tomatoes

Diced tomatoes add moisture and acidity to the beef filling. Drain them before adding so the casserole doesn’t become watery.

Spices

Cumin, chili powder, smoked paprika, and oregano create the warm, earthy flavor associated with Mexican-inspired dishes.

Adjust the chili powder according to your preferred level of heat.

Cheese

Monterey Jack melts beautifully and creates a creamy topping, while cheddar adds sharper flavor.

For a more traditional touch, finish the casserole with a little queso fresco.

How to Make Baked Beef Chiles Rellenos Casserole

Step 1: Roast the Poblano Peppers

Preheat your oven to 425°F (220°C).

Place the poblano peppers on a baking sheet and lightly brush them with olive oil.

Roast for approximately 15–20 minutes, turning them halfway through, until the skins become blistered, darkened, and tender.

The peppers should look beautifully roasted with charred patches across the skin.

Transfer them to a bowl and cover loosely with foil.

Allow them to steam for about 10 minutes. This makes removing the skins much easier.

Step 2: Peel and Prepare the Peppers

Once the peppers are cool enough to handle, gently peel away the loosened skin.

Cut a small opening down the side of each pepper and carefully remove the seeds and membranes.

Try to keep the peppers as intact as possible, although don’t worry if they tear slightly.

Set the roasted peppers aside.

Step 3: Cook the Beef Filling

Reduce the oven temperature to 375°F (190°C).

Heat the olive oil in a large skillet over medium heat.

Add the diced onion and cook for approximately 3–4 minutes, until softened and translucent.

Add the minced garlic and cook for another 30 seconds.

Add the ground beef.

Cook for approximately 6–8 minutes, breaking it apart with a wooden spoon until browned and fully cooked.

Drain excess grease if necessary.

Step 4: Season the Beef

Add the cumin, chili powder, smoked paprika, oregano, salt, and black pepper.

Stir thoroughly so the spices coat the beef.

Add the drained diced tomatoes and cook for another 2–3 minutes.

The filling should smell rich, smoky, and savory.

Remove the skillet from the heat and stir in the chopped cilantro.

Step 5: Prepare the Egg Mixture

In a large bowl, whisk together:

• Eggs
• Milk or unsweetened almond milk
• Salt
• Black pepper
• Cumin

Whisk until the mixture is smooth and lightly frothy.

The eggs will create a soft, fluffy layer around the beef and peppers as they bake.

Step 6: Assemble the Casserole

Lightly grease a 9 × 13-inch baking dish.

Arrange half of the roasted poblano peppers across the bottom.

Spoon half of the seasoned beef mixture over the peppers.

Sprinkle with part of the Monterey Jack and cheddar cheese.

Repeat with the remaining peppers, beef, and cheese.

Finally, slowly pour the egg mixture evenly over the entire casserole.

Give the baking dish a gentle shake so the egg mixture settles into the layers.

Step 7: Bake Until Golden

Place the casserole in the 375°F oven.

Bake for approximately 35–40 minutes, or until the egg mixture is completely set and the cheese is melted and golden.

The edges should look lightly browned, while the center should be firm rather than liquid.

If you want an extra golden cheese topping, broil for 1–2 minutes at the end.

Watch carefully because cheese can brown quickly under the broiler.

Step 8: Rest Before Serving

Remove the casserole from the oven and allow it to rest for approximately 10 minutes.

This helps the layers settle and makes slicing much easier.

Garnish with fresh cilantro, avocado, or a squeeze of fresh lime.

Then cut into eight generous portions and serve warm.

Pro Tips and Variations

For the best flavor, take your time roasting the poblanos until the skins are nicely blistered. Let them steam before peeling so the skins come away more easily. If you’re sensitive to spice, remove all seeds and membranes. For extra heat, add diced jalapeño to the beef filling. Ground turkey or chicken can replace the beef for a lighter variation. You can also add sautéed mushrooms, zucchini, or spinach for more vegetables. For a richer casserole, use full-fat Monterey Jack and cheddar. If you’re meal prepping, divide the cooled casserole into individual containers for easy lunches throughout the week.

Frequently Asked Questions

What are chiles rellenos?

Chiles rellenos are traditionally roasted peppers filled with ingredients such as cheese or meat and often coated in an egg batter before being fried. This casserole version simplifies the idea by layering roasted peppers, seasoned beef, eggs, and cheese in one baking dish.

Is this casserole spicy?

Poblano peppers generally provide a mild-to-moderate heat, but their intensity can vary. Removing the seeds and membranes will make the dish milder.

Can I use ground turkey instead of beef?

Yes. Ground turkey is an easy substitute. You may want to add an extra teaspoon of olive oil or a little additional seasoning to maintain a rich flavor.

Can I make this casserole ahead of time?

Yes. You can assemble the casserole several hours ahead and refrigerate it until you’re ready to bake. For best results, allow the chilled casserole a few extra minutes in the oven.

Can I use bell peppers?

Yes. Bell peppers are a good choice if you want a much milder casserole. Green, red, or yellow bell peppers will each give the dish a slightly different flavor.

How do I prevent the casserole from becoming watery?

Drain canned tomatoes thoroughly and avoid adding excess liquid from the roasted peppers. Allowing the finished casserole to rest for 10 minutes before slicing also helps.

Can I make this keto-friendly?

The basic casserole is naturally relatively low in carbohydrates, but exact carb counts depend on the ingredients used. Choose unsweetened dairy or milk alternatives and check packaged ingredients when following a strict keto plan.

What Makes This an Anti-Inflammatory-Inspired Recipe?

The term “anti-inflammatory” is best understood here as a food-focused description rather than a medical claim. This casserole contains ingredients such as colorful peppers, garlic, onions, olive oil, herbs, and spices that can contribute useful nutrients and plant compounds to an overall balanced eating pattern.

No single recipe can treat or cure inflammation. Instead, dishes like this can be enjoyed as part of a varied diet that emphasizes vegetables, quality proteins, healthy fats, and minimally processed ingredients.
