Southwestern Spaghetti Squash

We’re just getting into that time of the year when I have to make extra room in my pantry for cans. That includes canned tomatoes, of course, and canned beans. They are such a simple way to add protein to bulk up vegetarian and vegan dishes.

I absolutely love black beans in soups and salads, but they are also great paired with different varieties of roasted squash. That includes my butternut squash black bean quinoa and this southwestern spaghetti squash. Both have cumin and other dried seasonings along with cilantro.

And it is a fantastic base for a vegan main dish!

How To Roast Spaghetti Squash

My favorite way to cook spaghetti squash is to roast it. All you have to do is slice one in half lengthwise and remove the seeds by scoping them out with a spoon. After that, drizzle the flesh with olive oil and season it with salt and pepper.

Then roast the squash halves cut-side down on a sheet pan in the oven. Once it is ready, you can use a fork to remove the flesh. By dragging the teeth of the fork, the squash will naturally come out in spaghetti-like strands.

Roasting does add some flavor, but in general spaghetti squash is pretty plain, so you can do a lot with it. This is such a great opportunity!

For example, don’t hesitate to create a lighter version of a pasta dish and swap out the noodles for spaghetti squash.

Ingredients for Southwestern Spaghetti Squash

The Ingredients

This is what you need for this vegan recipe:

  • Spaghetti squash: Look for squash that feels heavy for its size. It should have smooth skin and no soft spots.
  • Bell peppers: The recipe calls for two peppers, one red and the other orange. You can use red, orange or yellow peppers.
  • Onions: Red onions are my go-to for the Southwestern blend of flavors and spices.
  • Black beans: Drain and rinse the black beans in cold water in a colander before adding them to the skillet.
  • Corn: I prefer canned corn rather than frozen corn kernels because they warm at the same time as the canned black beans.
  • Dried spices: The seasonings are a mix of cumin, chili powder, paprika, onion powder and garlic powder.
  • Salt & pepper: In addition to the spices, the seasoning blend has kosher salt and black pepper.
  • Cilantro: Along with the spaghetti squash, I fold in lots of chopped cilantro for something fresh and herby.
  • Avocado: To finish off the squash, I add diced avocado when everything has finished cooking.

  5. Heat the olive oil in a large skillet and sauté the diced onions.
  6. Add the bell peppers to the skillet and continue sautéing.

What To Do with Leftovers

You can store leftovers in an airtight container in the refrigerator for up to 3 days.

To reheat, microwave the squash in 30-second blasts. After each one, I stir everything around in the bowl to distribute the heat.

Wait to add the avocado and more cilantro until the squash is out of the microwave. Think of them as the final garnish.
