Ingredients for Baked Beef Chiles Rellenos Casserole
For the Casserole Layers
- 4–5 large poblano peppers (roasted and peeled)

- 4 large eggs
- 1 cup milk
- 2 tablespoons flour
- ½ teaspoon salt
- ½ teaspoon baking powder
Instructions
1. Roast the Poblanos
Place poblano peppers under a broiler or over an open flame until the skins blister and char. Place in a bowl, cover, and allow them to steam for 10 minutes. Peel off the skins, remove seeds, and slice open.
2. Cook the Beef Mixture
In a skillet, sauté onion until soft. Add garlic, then ground beef. Cook until browned, breaking apart meat. Season with salt, pepper, cumin, and chili powder. Drain excess fat.

Preheat oven to 375°F (190°C). Grease a 9×13 baking dish.
• Lay half the roasted peppers on the bottom
• Add the cooked beef mixture
• Sprinkle Monterey Jack and cheddar cheese
• Layer remaining roasted peppers over the top
4. Prepare the Egg Mixture
Whisk eggs, milk, flour, baking powder, and salt. Pour evenly over the layered casserole.
5. Bake
Bake for 35–40 minutes until puffed, golden, and set in the center.
6. Rest and Serve
Let cool 10 minutes before slicing so layers hold together. Serve topped with cilantro, salsa, or sour cream.

Notes
Expert Tips for the BEST Chiles Rellenos Casserole
Roast the peppers well
The deeper the blistering, the richer the flavor. Poblanos roasted correctly should be soft and smoky.
Drain the beef
Too much grease makes the casserole soggy—drain most or all of it.
Use freshly shredded cheese
Pre-shredded cheese contains anti-caking agents that prevent melting. Fresh cheese melts smoother and richer.
Let it rest before slicing
The egg mixture firms up while cooling, making slicing easier.
Flavor Variations
• Green Chile Beef Casserole
Use canned green chiles instead of whole roasted poblanos.
• Spicy Version
Add jalapeños, pepper jack cheese, or a pinch of cayenne.
• Low-Carb / Keto
Replace flour with almond flour and use heavy cream instead of milk.
• Breakfast Chiles Rellenos Casserole
Add scrambled eggs, chorizo, and more cheese.
