Ingredients You’ll Need

12 ounces whole roasted green chiles: These can be found fresh or canned; they add a smoky, earthy depth. For a milder flavor, consider using chopped green chiles.
½ lb Monterey Jack cheese, sliced into sticks: This cheese offers a creamy melt. Swap for Pepper Jack for some heat or Cotija for a crumbly texture.
2 large eggs, room temperature: Eggs help bind the casserole together, adding richness. Warm eggs mix better for a fluffier texture.
½ cup all-purpose flour: This adds structure to the dish; gluten-free flour works well as a substitute for those with dietary restrictions.
1 teaspoon kosher salt: This brings out the flavors in the dish, but feel free to adjust according to your taste.
2 cups milk: Whole milk creates a creamier texture, but you can use low-fat or a dairy-free option for a lighter alternative.
1 cup shredded Jack cheese: This adds a decadent cheesy layer—feel free to mix with cheddar or Cotija for extra flavor.

How to Make Chile Relleno Casserole

Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×9 inch baking dish (or an 8×11 if you have it on hand).
Prepare the Chiles: Rinse the roasted green chiles in cold water. Carefully scrape out the seeds and inside veins, adjusting the heat according to your preference. Stuff each chile with 1-2 sticks of Monterey Jack cheese, then place them in the greased baking dish.
Make the Custard Mixture: In a mixing bowl, beat 2 large room-temperature eggs. Gradually add ½ cup all-purpose flour, 1 teaspoon kosher salt, and 2 cups of milk, whisking until smooth and lump-free.
Assemble the Casserole: Pour the egg mixture over the stuffed chiles in the baking dish. Top with 1 cup of shredded Jack cheese before putting it in the oven.
Bake to Perfection: Bake the casserole for 1 to 1 ½ hours, or until the top is browned and the center is firm. Let it cool slightly before serving to let those flavors settle.

Storing & Reheating

Leftovers? No problem! Store Chile Relleno Casserole in an airtight container in the refrigerator for up to 4 days. For longer storage, you can freeze it for up to 3 months. When reheating, place portions in the microwave on medium power for about 3-5 minutes or until heated through, and consider topping it with a sprinkle of fresh cheese for that melty indulgence.

Chef’s Helpful Tips

Ensure your eggs are at room temperature; this helps to create a smoother mixture.
Avoid over-stirring the egg and milk mixture, as this may introduce too much air and create a spongy texture.
For a fun twist, try topping the casserole with fresh pico de gallo or avocado slices for brightness.
If your casserole edges begin to brown too quickly, simply cover it loosely with foil to prevent burning.
Make this dish ahead of time! Just prepare the casserole and keep it in the refrigerator overnight before baking—perfect for meal prep.

Indulging in this rich and comforting Chile Relleno Casserole feels incredibly satisfying. The blend of flavors melds beautifully, creating a dish that’s bound to become a family favorite. So go ahead, add your personal spin—whether it’s a extra layer of spice or an additional veggie—and enjoy this delight straight from the oven!

Recipe FAQs

Can I use frozen green chiles?

Absolutely! Frozen roasted green chiles can be a great alternative, just make sure to thaw them beforehand and pat dry to remove excess moisture.

What if I don’t have Monterey Jack cheese?

You can easily substitute it with cheddar, Pepper Jack for heat, or Cotija for a crumbly texture, depending on what you have on hand.

Is this casserole spicy?

The spiciness largely depends on the type and amount of chiles used. For a milder version, opt for canned green chiles or remove all the seeds from fresh chiles.

Can I make it vegetarian?

Certainly! Just make sure all cheese and any additional toppings are vegetarian-friendly. This casserole is naturally meat-free, making it a wholesome option for any diet.
