Spaghetti squash is a great way to bulk up meals or a perfect option if you’re looking to consume less pasta. 

I mean, I love pasta with all my heart but I probably shouldn’t live on the stuff.

A few years ago I taught you how to cook spaghetti squash in the microwave so if you’re short on time (or don’t want to turn on the oven!) go ahead and use that method for the squash vs. roasting. 

Both result in delicious outcomes. 

For the filling, I went full-on Southwest flavor with the addition of corn, black beans, tomatoes, and spicy pepper jack cheese.

What is spaghetti squash?

If you’re new to the world of the squash you’ll want to get acquainted pretty quickly!

Spaghetti squash is a medium-sized squash that typically harvested around early fall but can be found in the grocery store almost year-round. 

When cooked the inside of the squash is easily shreddable into long skinny strands that are reminiscent of angel hair pasta. 

Does spaghetti squash taste like pasta?

No, but texturally it can be very similar. 

While it is still squash it’s a great replacement for paste. Especially if you are on a lower-carb diet. 

Plus, in my opinion, it’s actually pretty darn delicious.

Can I make any substitutions to this recipe?

Of course! I’ve made several substitutions over the years to fit what I have on hand. 

  • Want a little more spice? Use chorizo instead of ground beef.
  • Don’t have a lot of spices on hand? Use a packet of taco seasoning!
  • Not a fan of pepper jack? Use any other melting cheese you like.
  • Can’t find black beans? Pinto or kidney beans are a great substitute!
  • Do I have to restuff the squash? Nope, I just like to restuff it after I mix it together and melt the cheese in the oven. However, you can easily mix in the pan, sprinkle the cheese on top, put on a lid, and let the steam melt the cheese.

Southwest Taco Stuffed Spaghetti Squash

Yield: 4 servings
Prep Time: 10 minutes
Cook Time: 1 hour 15 minutes
Total Time: 1 hour 25 minutes

This Southwest taco stuffed spaghetti squash is packed full of ground beef, vegetables, delicious spices, and herbs and topped with spicy pepper jack cheese. Super simple to make and a total crowd-pleaser. This dish is 100% comfort food!

Ingredients

  • 1 (4 pound) spaghetti squash
  • 2 tablespoons olive oil, divided
  • Kosher salt and pepper, to taste
  • 1/2 pound ground beef
  • 1 red bell pepper, diced
  • 1 medium yellow onion, diced
  • 1 small jalapeno, seeded and minced
  • 3 cloves garlic, minced
  • 2 teaspoons chili powder
  • 2 teaspoons smoked paprika
  • 1 teaspoon cumin
  • 1 (14 ounce) can diced tomatoes
  • 1 (14 ounce) can black beans, drained and rinsed
  • 1 cup frozen corn kernels
  • 1/4 cup minced cilantro
  • Kosher salt and pepper, to taste
  • 1 cup shredded pepper jack cheese

Instructions

  1. Preheat oven to 350 degrees and line a rimmed baking sheet with a Silpat or parchment paper.
  2. Place whole spaghetti squash in the microwave for 5 minutes. This helps slightly soften the squash so it's easier to cut open.
  3. Remove from the microwave and carefully cut in half, lengthwise. Scoop out the seeds and pulp from the middle.
  4. Drizzle each half with 1 tablespoon olive oil and season liberally with kosher salt and pepper.
  5. Roast for 1 hour or until the flesh of the squash will shred when scraped with a fork.
  6. While the squash is cooking make the meat and vegetable filling.
  7. In a large skillet set over medium-high heat add ground beef and break up with a spatula.
  8. Cook until browned and remove ground beef to a plate, wipe out any grease, and set the skillet back on the heat.
  9. To the pan add 1 tablespoon olive oil and once the oil is hot add in red bell pepper, onions, and jalapenos. Saute until the vegetables are soft.
  10. Add in the garlic, chili powder, smoked paprika, cumin, and tomatoes. Cook until the tomato juice has cooked off and the mixture is thick.
  11. Add in the black beans, corn kernels, and cilantro. Stir to combine and remove from the heat.
  12. Add the ground beef back to the skillet and stir to combine.
  13. Once the squash is fully cooked remove from the oven and carefully scrape and fluff the flesh until fully shredded.
  14. Remove the shredded squash and add it to the skillet with the ground beef and vegetables.
  15. Toss to combine so the shredded squash is mixed with the meat and vegetables. Taste and season with salt and pepper, if needed.
  16. Stuff the empty squash halves with the filling.
  17. Top with cheese and place under the broiler for about 15 minutes to melt and brown the cheese.
  18. Scoop out of the squash and serve. A 4-pound squash should give you enough for 4 servings, 2 servings per squash half.

I fixed this last night and my wife and I both LOVED it. It's a great recipe and will definitely make it again. I did substitute "meat" crumbles for the ground beef and used a non-dairy pepper jack cheese and the flavors were wonderful. Thank you!
