Ingredients You’ll Need
Gathering the right ingredients is crucial for crafting the perfect Chile Relleno Casserole. Here’s what you’ll need:
1. Main Ingredients
- 4 large poblano peppers: These smoky, mildly spicy peppers form the heart of the dish, bringing that signature flavor and a bit of heat.
- 1 cup cornmeal: Used to create a base layer for the casserole, offering texture and a complementary flavor.
- 2 cups shredded cheese: A blend of Monterey Jack and cheddar brings melty goodness to the dish, enhancing every bite with creaminess.
- 1 can (15 oz) diced tomatoes: Adds moisture and acidity, balancing the richness of the cheese and peppers.
- 1 cup milk: Ensures the casserole remains tender and moist, giving it the right consistency.
- 4 large eggs: Acts as a binding agent, giving the casserole structure and helping to set everything as it bakes.
- 1 teaspoon garlic powder: A pinch of garlic brings depth to the dish and elevates the overall flavor profile.
- 1 teaspoon cumin: This warm spice not only enhances the taste but adds an authentic Mexican flair.
- Salt and pepper to taste: Essential for allowing all the flavors to shine through.
2. Optional Additions
Feel free to mix things up according to your personal preferences or dietary restrictions:
- For extra spice: Add a pinch of cayenne or red pepper flakes to the cheese mixture.
- For a vegetarian twist: Substitute the cheese with plant-based cheese options to make it dairy-free.
- Extra protein: Add cooked ground beef or sausage for a heartier dish.
- For a smoky flavor: Consider using chipotle peppers in adobo sauce for added depth.
3. Special Garnishes
Don’t forget the finishing touches! Here are some garnishes that will not only enhance the dish visually but add an extra pop of flavor:
- Fresh cilantro: Chopped cilantro adds a fresh, vibrant flavor.
- Sour cream or Greek yogurt: A dollop of sour cream on top offers creaminess and balances spice.
- Avocado slices: Creamy avocado will contrast the casserole’s richness while adding a wonderful texture.
- Sliced jalapeños: For those who love heat, fresh jalapeños provide an additional bite.

Step-by-Step Instructions
Now that you have your ingredients ready, let’s walk through the simple steps to whip up your Chile Relleno Casserole:
1. Prepare the Poblano Peppers
Start by preheating your oven to 375°F (190°C). To prepare the poblano peppers, you can either roast them under the oven broiler or over an open flame until the skin is charred. This process not only enhances their flavor but also makes peeling easier. After charring, place them in a bowl covered with plastic wrap for about 10 minutes to steam, which helps loosen the skin. Once they are cool enough to handle, peel off the skin, slice open, and remove the seeds.
2. Mix the Base
In a large mixing bowl, combine the cornmeal, diced tomatoes (with their juice), milk, eggs, garlic powder, cumin, salt, and pepper. Whisk it all together until smooth and well-combined.
3. Layer the Ingredients
Spread a layer of the cornmeal mixture on the bottom of a greased 9×13-inch baking dish. Place the peeled and opened poblano peppers on top, spacing them out evenly. Generously sprinkle the shredded cheese over the peppers, and then pour the remaining cornmeal mixture on top, making sure to cover the cheese entirely.
4. Bake the Casserole
Cover the dish with aluminum foil and bake for 25-30 minutes in the preheated oven. After this time, remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and set. You should see it puffing slightly in the oven.
5. Let it Rest
Once cooked, remove the casserole from the oven and let it sit for about 10 minutes before serving. This resting period allows the flavors to meld together and makes it easier to slice.
Serving and Storage Tips
Your Chile Relleno Casserole is now ready to shine at the dinner table! Serve it warm, garnished with your favorite toppings. This dish pairs well with a side salad or some simple Mexican rice. For leftovers, store the casserole in an airtight container in the refrigerator for up to 3 days, or you can freeze it, tightly wrapped, for up to 3 months. Reheat in the oven at 350°F (175°C) until warmed through.
Helpful Tips
- Choosing the right peppers: Poblano peppers are the traditional choice for this dish due to their mild heat and rich flavor. If you can’t find them, Anaheim or hatch peppers can be a suitable substitute.
- Make ahead: You can prepare the casserole ahead of time and store it in the refrigerator before baking. Just add a few extra minutes to the oven time if it’s cold from the fridge.
- Adjust for spice preference: If you love spice, consider using hotter peppers like jalapeños or serranos.
