How to Make Easy Chile Relleno Casserole
-
Prep Peppers: Broil the poblano peppers on both sides until the skin is nicely blackened, about 3-4 minutes each side. Then, steam them in a zip-lock bag for 5-7 minutes—this makes peeling a breeze—before removing the skins and seeds.
-
Preheat Oven: Set your oven to 350°F and prepare an 8-inch baking dish by giving it a light coating of cooking spray, ensuring your casserole won’t stick.
-
Make Batter: Separate the egg whites from the yolks. Beat the egg whites until stiff peaks form—this is key for fluffiness! Next, gently fold in the yolks, followed by the flour, milk, baking powder, and a pinch of salt and pepper until the batter is smooth.
-
Assemble Casserole: Pour half of the batter into your prepared dish. Layer with half of the roasted poblano peppers and some grated cheese. Repeat this process with the remaining ingredients, ending with a generous topping of cheese.
-
Bake: Place the casserole in the preheated oven and bake for about 30 minutes, or until the casserole is nicely set and the top is golden brown.
-
Prepare Sauce: While your casserole bakes, char the tomatoes, onion, jalapeno, and garlic in a skillet until fragrant. Blend these ingredients together with the fried tortilla until smooth, then simmer in the skillet for 3-5 minutes to develop the flavor.
-
Serve: Once baked, allow the casserole to cool for 5-10 minutes for easier slicing. Serve warm, topped with the freshly made sauce and garnished with cilantro, lime wedges, and sour cream for added richness.
Optional: Drizzle with your favorite hot sauce for an extra kick!

Easy Chile Relleno Casserole Recipe FAQs
How should I select ripe poblano peppers for my casserole?
Absolutely! Look for firm poblano peppers with a smooth, shiny skin—these are the freshest! Avoid any that have dark spots all over or feel too soft, as they may be overripe. A vibrant green color is a great indicator of flavor and quality!
What is the best way to store leftover Easy Chile Relleno Casserole?
Leftover casserole can be kept in an airtight container in the fridge for up to 3 days. To maintain its delicious taste, it’s best enjoyed fresh—simply reheat it in the microwave or oven until warmed through!
Can I freeze the Easy Chile Relleno Casserole before baking?
Indeed! You can assemble the casserole, but skip baking it. Wrap the dish tightly with foil and freeze for up to 2 months. When you’re ready to enjoy it, thaw it in the refrigerator overnight, then bake as directed.
What adjustments can I make to cater to dietary restrictions?
Very! For a gluten-free option, swap regular flour for a gluten-free blend. If you’re avoiding dairy, feel free to use non-dairy milk and plant-based cheese alternatives. Additionally, you can substitute chicken bouillon with a vegetarian version to keep the dish fully vegetarian.
Why is my casserole not setting properly?
Don’t worry! If your casserole isn’t setting, it might need a little extra baking time. Ovens can vary, so check around the 30-minute mark and keep baking until the center is firm and the top is golden brown. If your egg whites weren’t beaten to stiff peaks, that can also affect the fluffiness. Make sure to whip them well for the best results!
How do I make sure my tomato sauce has the right consistency?
Certainly! If your sauce turns out too thick while simmering, gradually add water, one tablespoon at a time, and stir until you reach your desired consistency. Just remember to let it simmer a bit longer to blend those wonderful flavors together!
