Baked Beef Chiles Rellenos Casserole Recipe
Introduction
Baked Beef Chiles Rellenos Casserole offers a comforting twist on the classic stuffed pepper dish. With smoky poblano peppers filled with seasoned ground beef and topped with a cheesy egg mixture, this casserole is perfect for a hearty family meal.

Ingredients
- 8 large poblano peppers
- 1 lb ground beef
- 1 onion, chopped
- 2 cloves garlic, minced
- 1 teaspoon cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 can (15 oz) diced tomatoes, drained
- 2 cups Monterey Jack cheese, shredded
- 3 eggs
- 1 cup milk
- 1/3 cup all-purpose flour
- 1 teaspoon baking powder
Instructions
- Step 1: Char the poblano peppers by placing them under a broiler or over an open flame until the skins blister. Transfer peppers to a bowl, cover with plastic wrap, and let steam for 10 minutes. Peel off the skins and make a slit down one side of each pepper to remove the seeds.
- Step 2: In a skillet over medium heat, cook ground beef with chopped onion and minced garlic until the beef is browned and onions are soft. Drain excess grease. Stir in cumin, smoked paprika, salt, black pepper, and diced tomatoes. Cook until heated through.
- Step 3: Fill each poblano pepper with the beef mixture and arrange them in a greased 9×13-inch baking dish. Sprinkle half of the shredded Monterey Jack cheese over the stuffed peppers.
- Step 4: In a mixing bowl, whisk together eggs, milk, flour, and baking powder until smooth. Pour the mixture evenly over the peppers. Sprinkle the remaining shredded cheese on top.
- Step 5: Preheat the oven to 350°F (175°C). Bake the casserole for 35 to 40 minutes, or until the center is set and the top is golden brown.
Tips & Variations
- Keep a close eye on the peppers while charring to avoid burning the skins.
- Use a small spoon to evenly distribute the beef filling into each pepper for consistent flavor.
- Swap Monterey Jack cheese with cheddar or pepper jack to add more sharpness or spiciness.
- Add an extra tablespoon of flour to the egg mixture if you prefer a thicker, firmer topping.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 325°F (160°C) until warmed through to maintain texture and flavor. Avoid microwaving to keep the topping from becoming soggy.
