Why This Recipe Works

We roasted the oblong yellow squash in the traditional method, simply halving it and roasting until the sweet strands could be easily shredded from the skins with a fork. While the squash roasted, we built a flavorful base for our casserole by blooming minced garlic, smoked paprika, and cumin in the microwave. Incorporating black beans, corn, and tomatoes turned the spiced squash into a true meal while reinforcing the Mexican flavors. Scallions lent a subtle oniony flavor without overpowering the sweet squash, as well as nice pop of color. Minced jalapeño gave just the right amount of gentle heat. We sampled a variety of toppings, but creamy avocado and mellow, slightly briny queso fresco won us over. We also enjoyed serving our squash with a squeeze of lime juice.
