How to Make Southwest Taco Stuffed Spaghetti Squash
-
Preheat your oven to 350°F and prepare a baking sheet with parchment paper for easy cleanup. This sets the stage for perfectly roasted squash.
-
Microwave the spaghetti squash for 5 minutes to soften it up, making it easier to cut. Then, slice it in half lengthwise and scoop out the seeds—this creates space for all that delicious filling!
-
Drizzle each half of the squash with olive oil, followed by a sprinkle of kosher salt and black pepper. Roast them for 1 hour, or until the flesh is shredable and tender.
-
Brown the ground beef in a skillet over medium-high heat until fully cooked, about 5-7 minutes. Don’t forget to drain off any excess fat before setting the beef aside.
-
Sauté the chopped red bell pepper, onion, and jalapeño in the same skillet with a bit of leftover olive oil for about 5 minutes, until they’re soft and fragrant.
-
Add the minced garlic, chili powder, smoked paprika, cumin, and diced tomatoes. Stir everything together and let it cook until thickened, about 5 more minutes.
-
Stir in the black beans, corn, and chopped cilantro, seasoning to taste. Integrate the browned beef back into the mixture, ensuring everything is well-combined.
-
Shred the roasted squash with a fork, creating those pasta-like strands. Mix the squash strands into the beef and vegetable filling until evenly coated.
-
Stuff each squash half generously with the mixture, topping them off with shredded cheese. Return the stuffed squash to the oven for about 10 minutes to melt the cheese perfectly.
-
Serve warm, garnished with a dollop of sour cream and a sprinkle of fresh cilantro for that extra burst of flavor!
Optional: Add avocado slices for a creamy texture.

Southwest Taco Stuffed Spaghetti Squash Recipe FAQs
What type of spaghetti squash should I choose for this recipe?
Absolutely! Look for a spaghetti squash that feels heavy for its size and has a smooth, creamy skin. Avoid those with dark spots all over or soft spots, as they may be overripe. If necessary, you can substitute butternut squash, but keep in mind that the texture will differ slightly.
How should I store leftovers of my Southwest Taco Stuffed Spaghetti Squash?
Very important! Store any leftovers in an airtight container in the fridge for up to 3 days. Make sure to let it cool completely before sealing to avoid condensation, which can make it soggy. When you’re ready to enjoy them again, reheat in the oven at 350°F for about 15-20 minutes for the best results.
Can I freeze the stuffed spaghetti squash?
Of course! To freeze, allow the stuffed squash to cool entirely, then place individual portions in airtight containers or heavy-duty freezer bags. You can freeze it for up to 3 months. When ready to eat, thaw overnight in the fridge and reheat in the oven at 350°F until warmed through.
What can I do if my filling is too soupy?
No worries! If your filling turns out too soupy, try this: Allow it to simmer on the stove for a few extra minutes to let excess moisture evaporate. You can also mix in more beans or shredded squash to help absorb the liquid. Just keep stirring gently until it reaches your desired consistency.
Are there any dietary considerations for this recipe?
Absolutely! This dish is versatile and can easily accommodate different diets. If you’re cooking for someone with a beef allergy or seeking a healthier option, you can replace ground beef with ground turkey, shredded chicken, or even a plant-based protein.
