Ingredients
- 2 lbs spaghetti squash

- 2 bell peppers
- 11.5 oz corn (canned)
- 18 oz black beans (canned)

- 2 eggs
Instructions
- Step 1: Preheat the oven to 350°F (175°C).
- Step 2: Cook the spaghetti squash until tender by baking, microwaving, or boiling, then shred the flesh into noodle-like strands with a fork.
- Step 3: In a nonstick skillet, cook the ground turkey over medium heat until browned. Remove from heat and let it cool slightly.
- Step 4: In a large bowl, combine the shredded spaghetti squash, cooked turkey, chopped bell peppers, drained corn and black beans, green chiles, diced tomatoes with their juices, enchilada sauce, chili powder, cumin, salt, and eggs. Mix everything well.

- Step 7: Let the casserole rest for 10 minutes before serving to allow it to set.
Tips & Variations
- For a vegetarian version, replace ground turkey with cooked lentils or extra black beans.
- Add a diced jalapeño for extra heat.
- Use pepper jack cheese instead of mozzarella or Monterey Jack for a spicy kick.
- To speed up cooking, microwave the spaghetti squash halves for 10 minutes instead of baking.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the entire casserole in the oven at 350°F until heated through. This dish can also be frozen for up to 2 months; thaw overnight in the fridge before reheating.
How to Serve

FAQs
Can I use a different type of squash?
Yes, but spaghetti squash is recommended for its noodle-like texture. Other squashes won’t shred the same way and may alter the dish’s consistency.
Do I have to use eggs in the casserole?
The eggs help bind the casserole together, but if you prefer, you can omit them or use a flax egg as a vegan alternative.
