Pro Tips:

  1. Choose a good spaghetti squash: Look for one that’s firm, free of soft spots, and feels heavy for its size.
  2. Don’t skip seasoning the squash: A little olive oil, salt, and pepper go a long way in boosting the flavor.
  3. Form even meatballs: Use a cookie scoop or tablespoon to ensure your meatballs are all the same size. This helps them cook evenly.
  4. Use a jarred marinara you love: Since the sauce is a big part of this dish, pick one with great flavor. Or make your own if you have time!
  5. Don’t overmix the meatballs: Mix the ingredients until just combined so they stay tender and juicy.

Tools You’ll Need:

  • A slow cooker
  • Cutting board
  • Chef’s knife
  • Cookie scoop or tablespoon
  • Mixing bowl
  • Measuring spoons
  • Fork for shredding squash

Substitutions and Variations:

  • Meatballs: Swap turkey for chicken or lean ground beef.
  • Breadcrumbs: Use almond flour or gluten-free breadcrumbs to make it gluten-free.
  • Sauce: Any tomato-based sauce works—try arrabbiata for a spicy kick!
  • Cheese: Skip the Parmesan or use a dairy-free alternative if needed.

Make-Ahead Tips:

  • Meatballs: You can mix and roll the meatballs ahead of time and store them in the fridge for up to a day.
  • Squash: Prep the squash by slicing it and scooping out the seeds ahead of time so it’s ready to go.

Instructions:

1. Prep the Spaghetti Squash

Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with olive oil and sprinkle with salt and pepper.

4. Add the Sauce and Meatballs

Pour half the marinara sauce into the slow cooker around the squash. Add the meatballs on top, then pour the rest of the marinara sauce over the meatballs.

5. Cook

Cover and cook on low for 6-8 hours or high for 3-4 hours, until the squash is tender and the meatballs are fully cooked.

6. Shred the Squash

Carefully remove the spaghetti squash halves, and use a fork to scrape out the “noodles.” Serve with meatballs and sauce on top, garnished with fresh basil or extra Parmesan.
