Chile Rellenos Casserole

There’s something irresistible about the aroma of roasted chiles, bubbling cheese, and golden, fluffy eggs wafting through the kitchen. This Chile Rellenos Casserole takes all the bold, comforting flavors of the traditional Mexican dish and folds them into an easy, oven-baked delight. Each forkful melts in your mouth, layering spicy peppers, creamy cheese, and a tender egg base that feels like a warm hug at the end of a long day. Trust me, you’re going to love this.

Behind the Recipe

I first fell for Chile Rellenos at a tiny roadside diner in New Mexico, where the chef proudly served them smothered in homemade tomato salsa. But let’s be honest, stuffing and frying chiles on a busy weeknight isn’t always in the cards. So, this casserole version was born out of love and practicality. It keeps all the soul of the original dish but skips the deep fryer. It’s become a Sunday brunch staple in my home and a crowd favorite at potlucks.

Recipe Origin or Trivia

Chile Rellenos, which means “stuffed chiles” in Spanish, hail from Mexican cuisine, particularly the Puebla region. Traditionally made with poblano peppers stuffed with cheese or meat, dipped in egg batter, and fried, they date back to at least the 19th century. This casserole variation is a modern American twist that reflects the love for bold Mexican flavors with a simpler, family-style presentation.
