Ingredients Method

Ingredients

  

• 1 large spaghetti squash (about 3–4 pounds)
• 1 tablespoon olive oil
• 1 pound ground beef (90% lean is ideal)
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced
• 1 bell pepper (red or green), diced
• 1 can (10 ounces) red enchilada sauce or about 1 1/4 cups
• 1 teaspoon chili powder
• 1/2 teaspoon ground cumin
• 1/2 teaspoon smoked paprika (optional but great)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper
• 1 cup shredded cheese (Monterey Jack, cheddar, or a Mexican blend)
• 1/4 cup chopped fresh cilantro (optional, for garnish)
• 1 avocado, sliced (optional)
• Sour cream or Greek yogurt, for serving (optional)
• Lime wedges, for serving

Method

 

1. Preheat the oven. Set it to 400°F (200°C). Line a baking sheet with parchment for easier cleanup.
2. Prep the squash. Carefully slice the spaghetti squash in half lengthwise. Scoop out the seeds. Drizzle the cut sides with olive oil, then sprinkle with a pinch of salt and pepper.
3. Roast until tender. Place the squash cut-side down on the baking sheet. Roast for 35–45 minutes, until a fork easily slides into the flesh and the edges are just golden.
4. Cook the beef mixture. While the squash roasts, heat a large skillet over medium heat. Add the ground beef and cook, breaking it up, until no longer pink, about 5–6 minutes. Drain excess fat if needed.
5. Add aromatics and peppers. Stir in the diced onion, bell pepper, and garlic. Cook until softened and fragrant, 3–4 minutes.
6. Season and sauce. Add chili powder, cumin, smoked paprika, salt, and black pepper. Stir to coat. Pour in the enchilada sauce and simmer for 3–5 minutes to thicken slightly and meld flavors. Taste and adjust seasoning.
7. Shred the squash. When the squash is cool enough to handle, flip it over and use a fork to pull the strands into “spaghetti.” Leave the strands in the shells to use them as bowls, or transfer to a baking dish if you prefer.
8. Combine and top. Divide the beef mixture evenly between the two squash halves. Gently toss the strands and sauce together in the shells. Sprinkle the shredded cheese over the top.
9. Broil to melt. Set the oven to broil. Place the squash back in for 2–3 minutes, just until the cheese is melted and bubbling. Keep a close eye to avoid burning.
10. Garnish and serve. Top with cilantro and avocado if using. Add a dollop of sour cream or Greek yogurt and a squeeze of lime. Serve hot right from the shells.

What Makes This Special

This recipe gives you the comfort of classic enchiladas with a veggie-forward twist. The spaghetti squash roasts into tender strands that soak up the sauce instead of getting soggy.

The ground beef adds rich, savory flavor, and the cheese ties it all together. You still get the familiar enchilada spices and toppings, just in a lighter, spoonable package. It’s also easy to customize with your favorite add-ins, from beans to jalapeños.

Keeping It Fresh

Leftovers store well and taste even better the next day. Let the squash cool, then transfer to an airtight container. It will keep in the fridge for up to 4 days.

Reheat gently in the microwave or in a 350°F oven until warmed through. If it looks a little dry, add a spoonful of enchilada sauce or a splash of water before reheating. For freezing, it’s best to freeze the beef-and-sauce mixture separately from the roasted squash strands.

The squash can get watery after thawing, but it still works if you drain off excess liquid and reheat with a bit more sauce.

Health Benefits

Spaghetti squash is naturally low in calories and carbs, making it a smart swap for pasta or tortillas. It also brings fiber, which helps with fullness and digestion. Ground beef adds protein, iron, and B vitamins, supporting energy and muscle health.

If you choose a lean blend and drain any excess fat, you keep it balanced without losing flavor. You can also lighten things up by using reduced-fat cheese and topping with Greek yogurt instead of sour cream.

Common Mistakes to Avoid

• Undercooking the squash: If it’s too firm, you’ll get stiff strands that don’t mix well with the sauce. Cook until easily shreddable.
• Skipping the drain on the beef: Excess grease can make the dish heavy.

  Drain or blot before adding the sauce.

• Using too much sauce: It can make the squash watery. Start with the amount listed, then add more only if needed.
• Over-broiling the cheese: A quick melt is perfect. Burnt cheese will taste bitter.
• Forgetting to season: Taste as you go.

  A little salt and lime at the end brightens everything.

Variations You Can Try

• Bean Boost: Stir in 1 cup black beans or pinto beans with the sauce for extra fiber and protein.
• Spicy Kick: Add chopped jalapeño or use hot enchilada sauce. A pinch of chipotle powder adds smoky heat.
• Turkey or Chicken: Swap the ground beef for ground turkey or shredded rotisserie chicken.
• Veggie-Forward: Add corn, zucchini, or spinach to the skillet with the onion and pepper.
• Green Enchilada Spin: Use green enchilada sauce and pepper jack cheese for a tangy twist.
• Dairy-Free: Use a plant-based cheese or skip cheese and finish with avocado and an extra drizzle of sauce.
• Make-Ahead Casserole: Mix the shredded squash with the beef and sauce in a baking dish, top with cheese, and bake at 350°F until hot and melty.

FAQ

Can I cook the spaghetti squash in the microwave?

Yes. Pierce the squash all over with a fork, microwave for 5–6 minutes to soften, then cut, seed, and microwave cut-side down in a dish with a bit of water for 10–12 more minutes until tender.

Roasting has better flavor, but the microwave is fast.

What can I use if I don’t have enchilada sauce?

Mix tomato sauce with chili powder, cumin, garlic powder, a pinch of oregano, and a splash of vinegar. Simmer for a few minutes to thicken. It won’t be identical, but it works well in a pinch.

How do I keep the squash from getting watery?

Roast cut-side down for good caramelization, and let the squash sit a few minutes after roasting.

If it looks wet, gently press with paper towels. Don’t flood it with sauce—start modest and add more if needed.

Is this recipe gluten-free?

It can be. Most enchilada sauces are gluten-free, but some brands add thickeners with gluten.

Check the label to be safe, and you’re good to go.

Can I make it ahead?

Yes. Roast the squash and cook the beef mixture up to 2 days in advance. Store separately, then assemble, top with cheese, and broil right before serving.

What cheese works best?

Monterey Jack or a Mexican blend melts smoothly and has great flavor.

Cheddar is fine too. For extra stretch, mix in a little mozzarella.

How can I make it lower in fat?

Use 93–96% lean ground beef or ground turkey, reduce the cheese, and swap sour cream for plain Greek yogurt. The dish will still feel satisfying.
