How to Make Mexican Spaghetti Squash Casserole

This recipe is simple enough for busy weeknights, yet feels like a weekend treat. Here’s your step-by-step guide:

  1. Prep Your Squash: Preheat the oven to 350°F. Slice squash lengthwise and remove seeds. Place cut-side down on a baking sheet and roast for 35–40 minutes or until fork-tender. Once cool enough to handle, shred into spaghetti-like strands using a fork. Press lightly with paper towels to remove excess moisture.
  2. Cook the Turkey: While squash roasts, heat a skillet over medium heat. Cook ground turkey until browned, about 6–8 minutes. Drain excess moisture and season with salt, cumin, and chili powder.
  3. Mix the Filling: In a large mixing bowl, combine shredded squash, cooked turkey, finely chopped bell peppers, black beans, corn, canned diced tomatoes, green chiles, enchilada sauce, and remaining seasonings. Stir well to combine.
  4. Assemble the Casserole: Spoon mixture into a greased 9×13-inch baking dish. Smooth into an even layer and sprinkle cheese evenly across the top.
  5. Bake: Cover with foil and bake for 45 minutes. Remove foil and bake an additional 15 minutes or until bubbly and golden on top.
  6. Rest & Serve: Allow casserole to cool for 10 minutes before slicing. Garnish with fresh chopped cilantro, optional avocado slices, or a dollop of sour cream.

Troubleshooting & Swaps

Don’t worry if things aren’t picture-perfectthis casserole is super forgiving. Here’s how to pivot:

  • Too Watery? Press roasted squash strands gently with paper towels before adding to the mix.
  • Out of Turkey? Substitute with leftover rotisserie chicken or double the beans for a vegetarian version.
  • No Green Chiles? Add a few diced jalapeños or a shake of red pepper flakes for spice.
  • Cheese Isn’t Melting? Use freshly shredded cheese instead of pre-packaged (which often contains anti-caking agents).

Ground TurkeyShredded chicken or lean ground beef
CheeseCheddar, Pepper Jack, or dairy-free cheese
