Preheat your oven to 375°F (190°C). Grease an 8x8-inch or similarly sized casserole dish and set aside.
Wash and dice the zucchini and yellow squash into bite-sized pieces. Dice the tomatoes and onion as well. Mince the garlic cloves.
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook until softened, about 2-3 minutes.
Add the minced garlic to the skillet and cook for another 30 seconds until fragrant.
Stir in the zucchini, yellow squash, and corn. Cook for 5-7 minutes, stirring occasionally, until the vegetables are slightly tender but not fully cooked.
Add the diced tomatoes, chopped green chiles, salt, black pepper, and ground cumin. Continue to cook for another 2 minutes, until everything is well combined and heated through.
Remove the skillet from heat and stir in 1 cup of shredded cheese and the sour cream. Mix until the cheese is melted and the mixture is creamy.
Transfer the vegetable mixture into the greased casserole dish. Smooth the top with a spatula.
If using breadcrumbs, sprinkle them evenly over the top of the casserole. Then add the remaining 0.5 cup of shredded cheese on top.
Bake in the preheated oven for 25-30 minutes, or until the cheese is melted, bubbly, and golden brown.
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with chopped fresh cilantro, if desired.
Serve warm and enjoy your Calabacitas Squash Casserole!
