Why This Recipe Works

Spaghetti squash makes for a great pasta replacement or a fun side dish, but we wanted to showcase this versatile vegetable’s ability to work in a heartier casserole by adding beans and jazzing it up with southwestern-inspired flavors. While the squash halves roasted cut side down, we built a savory base for our casserole by using our favorite shortcut—blooming garlic, paprika, and cumin in oil in the microwave. Incorporating black beans, corn, and tomatoes turned the shredded squash into a meal. Minced jalapeño gave just enough heat for a gentle kick, and creamy avocado and slightly briny queso fresco rounded out the casserole.

Before You Begin

Crumbled feta can be substituted for the queso fresco. For a spicier dish, reserve and add the jalapeño seeds to the filling.
