Vegan Chile Rellenos Casserole

Sharon Palmer

The Mexican food tradition of chiles rellenos—essentially stuffed chiles—is a rich, flavorful one. This dish is the culmination of indigenous ingredients, such as spices and chiles, and Spanish cooking methods. Typically, Mexican-style chiles rellenos are stuffed chiles, covered with an egg batter and deep-fried. I wanted to create a healthier version, paying homage to those fabulous food traditions in Mexico, while keeping it easy, light and 100% plant-based. Yet this Vegan Chile Rellenos Casserole is vibrant, rich in flavor, and easy on the eyes, too!

Poblano chiles are commonly used for this recipe, as they have a mild, sweet flavor, and are the perfect size. Just roast them, and layer them with a rich tomato-quinoa filling, then plant-based cheese before baking. Check out my easy, step-by-step guide for making this recipe below.

Poblano Chiles from the farmers market in Ojai.

Step-By-Step Guide:

Slice Poblano chiles in half, scoop out seeds.
Place with cut side down in baking dish, drizzle with EVOO, and broil for 5-10 minutes.
When skin is slightly blackened, remove from oven and rest for a few minutes.
Peel away the skins from the chiles with your fingers.
Layer the roasted chiles on the bottom of the pan, with cut side up.
Sauté onions, zucchini, garlic, bell pepper, spices, corn, cooked quinoa, and canned tomatoes until tender.
Spoon the quinoa filling over the chiles.
Spread evenly over the chiles.
Cover with plant-based cheese and bake for about 30 minutes, until golden brown.
Remove from the oven.
Dish up into 8 servings and enjoy!
