Instructions
- Step 1: Preheat oven to 425°F. Slice 3 medium poblano peppers into 1/2-inch strips and place on a rimmed baking sheet. Drizzle with 2 tbsp olive oil, sprinkle 1 tsp salt, 1 tsp ground cumin, and 1/2 tsp garlic powder; toss to coat evenly. Roast for 15 minutes until peppers are softened and slightly charred.
- Step 2: While peppers roast, prepare the lime crema by whisking together 1/2 cup sour cream, 2 tbsp lime juice, 1/4 cup chopped cilantro, and 1 finely chopped jalapeño until smooth and tangy.
- Step 3: After roasting, remove poblano strips and add drained 15 oz black beans to the baking sheet. Drizzle remaining 1 tbsp olive oil over the beans and toss gently. Return tostadas to the oven for 5 minutes to warm.
- Step 4: To assemble, spread a spoonful of the lime crema over each of the 6 corn tostadas, top with roasted poblano strips, black beans, and a sprinkle of 1/3 cup crumbled cotija cheese and thinly sliced 1 small red onion. Serve immediately for a crunchy, smoky flavor.
