  • 3 pounds spaghetti squash (sliced in half lengthwise, seeds scraped with a spoon)
  • 1 packet taco seasoning
  • 14.5 ounces can fire roasted tomatoes (drained)
  • 2/3 cup canned black beans (rinsed and drained)
  • 1 cup shredded cheese – or more (I use a Mexican 4-cheese blend)
  • jalapeño slices (optional)
  • 1/4 cup fresh cilantro leaves (chopped (optional)
  • salt and pepper to taste

Simple avocado salsa

  • 2 medium tomatillos (peeled and chopped)
  • 1 clove garlic (peeled and chopped)
  • 1 large avocado (peeled, pitted and chopped)
  • 2 tablespoons fresh lime juice


  1. Preheat oven to 375ºF.
  2. Place spaghetti squash on a microwave safe plate or other microwave safe container. Place the cut side down (skin facing up). Microwave on high for 10 minutes.
  3. Take the spaghetti squash out of the microwave and shred with a fork. If the squash is still hard, microwave for another 2-3 minutes, or until tender.
  4. Transfer the shredded spaghetti squash to a large bowl.
  5. Add taco seasoning and gently toss.
  6. Add fire roasted tomatoes and black beans and gently toss.
  7. Brush a 1.5 quart casserole dish with a little olive oil (you can also use cooking spray).
  8. Pour the spaghetti squash mixture into the casserole dish and spread evenly.
  9. Sprinkle cheese and add a few slices of fresh jalapeño on top and bake for 20-25 minutes, or until cheese has melted.
  10. Meanwhile, make the simple avocado salsa by blending all the ingredients in a blender until smooth. Season with salt if needed.
  11. Take spaghetti squash casserole out of the oven and top with fresh salsa and cilantro. Serve immediately.
  12. Note: If you cannot find tomatillos, mash the avocado with a fork and season with a squeeze of fresh lime and a little salt.
