Detailed Method of Preparation

  1. Cook Squash: Preheat oven to 375°F (190°C). Halve the spaghetti squash and remove seeds. Brush with olive oil, season with salt and pepper, and place cut-side down on a baking sheet. Bake for 40-45 minutes until tender.
  2. Prepare Filling: In a pan, sauté onion and garlic. Add black beans, corn, diced tomatoes, cumin, and chili powder. Cook for 5-7 minutes.
  3. Combine: Once the squash is cool enough to handle, use a fork to scrape out the strands into a large bowl. Mix the spaghetti squash strands with the filling.
  4. Assemble Casserole: Transfer the mixture to a baking dish. Top with shredded cheese.
  5. Bake: Bake for 15-20 minutes or until the cheese is melted and bubbly.
  6. Garnish and Serve: Garnish with fresh cilantro before serving.

Tips for Culinary Success

  • Ensure the squash is fully cooked; it should be easy to scrape into strands.
  • Add a splash of lime juice to the filling for extra zest.
  • For a non-vegetarian version, add cooked ground beef or chicken.
