• Salt and black pepper to taste
• 1/4 cup fresh cilantro chopped, optional, for garnish

For the Egg Batter & Cheese

• 6 large eggs
• 1/2 cup milk whole or 2%
• 1/4 cup all-purpose flour

• 1/2 tsp salt
• 1/4 tsp black pepper

Equipment

• 9×13 inch baking dish
• Large Skillet
• Large Mixing Bowl
• Whisk
• Aluminum Foil
• Baking Sheet

Method

 

Prepare the Poblanos

1. Preheat oven to 400°F (200°C). Place poblanos on a baking sheet. Roast for 20-25 minutes, turning occasionally, until skins are blistered and charred. Transfer to a bowl, cover tightly with plastic wrap, and let steam for 10-15 minutes. Once cool enough to handle, peel off skins, remove stems and seeds, and slice peppers into 1-inch wide strips. Set aside. Reduce oven temperature to 375°F (190°C).

Cook the Ground Beef Filling

1. Heat olive oil in a large skillet over medium-high heat. Add ground beef and cook, breaking it apart with a spoon, until browned. Drain excess fat. Add chopped onion and cook until softened, about 5 minutes. Stir in minced garlic and cook for 1 minute more until fragrant.
2. Add diced tomatoes (undrained), diced green chiles, cumin, chili powder, and oregano. Season with salt and pepper. Bring to a simmer, then reduce heat to medium-low and cook for 5-7 minutes, allowing flavors to meld and liquid to reduce slightly. Set aside.

Assemble the Casserole

1. Lightly grease a 9×13 inch baking dish. Lay half of the prepared poblano strips evenly over the bottom of the dish.
2. Spread the entire ground beef filling evenly over the poblano layer.
3. Sprinkle 1 cup of shredded cheese over the ground beef filling.
4. Layer the remaining poblano strips over the cheese.

Prepare Egg Batter and Bake

1. In a large mixing bowl, whisk together eggs, milk, flour, baking powder, salt, and pepper until smooth and well combined.
2. Carefully pour the egg batter evenly over the poblano layers in the baking dish.
3. Sprinkle the remaining 1 cup of shredded cheese over the top.
4. Cover the baking dish loosely with aluminum foil. Bake for 30 minutes.
5. Remove the foil and bake for an additional 15-20 minutes, or until the egg is set, the cheese is bubbly and golden, and the casserole is heated through.

Rest and Serve

1. Let the casserole rest for 10-15 minutes before serving to allow it to set. Garnish with fresh cilantro, if desired. Serve warm.

Notes

For a spicier kick, use hot green chiles or add a pinch of cayenne pepper to the beef filling.
The casserole can be assembled ahead of time, covered, and refrigerated for up to 24 hours. Let it come to room temperature for 30 minutes before baking, and add 10-15 minutes to the baking time if baking from cold.
Store leftovers in an airtight container in the refrigerator for up to 3-4 days.

Pro Tips for Making This chile relleno casserole with ground beef

When I’m making this chile relleno casserole with ground beef, I’ve learned a few tricks over the years to ensure it turns out perfectly every time. These little insights, born from countless hours in my kitchen, make all the difference!

• 
  

  Perfectly Roasted Poblanos: Don’t rush the charring process for your poblano peppers. Getting a good, even char helps them peel easily and deepens their smoky flavor. Once charred, immediately place them in a bowl and cover with plastic wrap for 10-15 minutes to steam. This makes the skins practically slide right off.

  
  
• 
  

  Flavorful Beef Filling: Building layers of flavor in your ground beef filling is key. Don’t skip caramelizing your onions and garlic before adding the beef. And remember, the spices—cumin, chili powder, and oregano—need a moment to bloom in the pan, releasing all their wonderful aromatics. This makes your chile relleno casserole with ground beef truly sing!

  
  
• 
  

  Don’t Overmix the Batter: When you’re preparing the egg batter, mix it just until combined. Overmixing can develop the gluten in the flour, leading to a tougher texture. We want a light and fluffy custard-like base to cradle all that savory goodness.

  
  
• 
  

  My Secret Trick: I always let my casserole rest for at least 10-15 minutes after it comes out of the oven. This seemingly small step allows the ingredients to settle, the cheese to firm up just enough, and the flavors to meld beautifully. It ensures every slice of this chile relleno casserole with ground beef holds together perfectly and tastes even better.

  
  

Fun Variations for chile relleno casserole with ground beef

One of the things I adore about home baking and cooking is the freedom to play! This chile relleno casserole with ground beef is a fantastic canvas for your own creative touches. Don’t be shy about making it uniquely yours!

Spice it Up!

If you love a little more heat, consider adding a finely diced jalapeño or serrano pepper to your ground beef filling. My friend, Elena, always asks me to include a dash of cayenne pepper for an extra kick that warms you from the inside out. Just remember to adjust to your family’s preference!

Veggie Delight

For those looking to lighten things up or add more vegetables, you could swap half of the ground beef for finely chopped mushrooms or black beans. You could even add a layer of sautéed corn or zucchini alongside the poblanos. This chile relleno casserole with ground beef can easily adapt to a more garden-fresh profile.

Cheese Please!

While Monterey Jack is classic, feel free to experiment with other cheeses. A blend with some sharp cheddar or a touch of smoky Gouda could add a wonderful dimension. My neighbor, who adores a robust flavor, swears by adding a sprinkle of cotija cheese right before serving for a salty, tangy finish!

What to Serve With chile relleno casserole with ground beef

Refrigerating Leftovers

Once cooled, cover any leftover chile relleno casserole with ground beef tightly with plastic wrap or transfer it to an airtight container. It will keep wonderfully in the refrigerator for up to 3-4 days. To reheat, I like to gently warm individual portions in the microwave or place larger pieces in a preheated oven at 300°F (150°C) until heated through, usually about 15-20 minutes, covered with foil to prevent drying out.

Freezing for Later

This casserole freezes beautifully, which is excellent news for make-ahead meals! Allow the cooked chile relleno casserole with ground beef to cool completely, then cut it into individual portions. Wrap each portion tightly in plastic wrap, then aluminum foil, and place in a freezer-safe bag or container. It will stay fresh for up to 2-3 months. Thaw overnight in the refrigerator before reheating as directed above. My personal tip? A light dusting of fresh cilantro after reheating always brings it back to life with a burst of freshness!

Nutritional Benefits

While this chile relleno casserole with ground beef is undeniably a comfort food, it also offers some lovely nutritional perks. The ground beef provides a hearty source of protein, essential for building and repairing tissues, while the poblano peppers contribute a dose of vitamins and fiber. It’s a treat that’s both satisfying and nourishing, embodying my philosophy of creating delicious, wholesome meals with simple ingredients.
