📝 Instructions

11 steps

1. Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

2. Slice the zucchini and yellow squash into thin rounds, about 1/4 inch thick.

3. In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened.

4. Stir in the minced garlic and cook for 1 minute, until fragrant.

5. Add the sliced zucchini and yellow squash to the skillet. Sauté for 5-7 minutes until the squash is slightly softened.

6. Stir in the black beans, canned diced tomatoes with green chilies (including juices), frozen corn kernels, chili powder, ground cumin, smoked paprika, salt, and black pepper. Mix well until evenly combined, then remove from heat.

7. Spread the vegetable mixture evenly in the prepared baking dish.

8. Sprinkle 1 1/2 cups of the shredded Mexican blend cheese over the vegetable mixture.

9. In a small bowl, combine the panko breadcrumbs and melted butter. Spread the breadcrumb mixture evenly over the cheese layer.

10. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling.

11. Remove the casserole from the oven and let it cool for 5-10 minutes. Sprinkle with the remaining 1/2 cup of shredded cheese and chopped cilantro (if using) before serving.
