The turkey meatballs are a great source of lean protein, and are seasoned to perfection with a flavorful blend of spices and herbs.

Let’s Chat Spaghetti Squash

Here are some tips for picking out good squash for this Spaghetti Squash With Meatballs recipe :

  • Look for squash that is firm and heavy for its size. Avoid squash that feels soft or has any noticeable dents or bruises, as these can indicate that the squash is overripe or damaged.
  • Check the color of the squash. A good spaghetti squash should have a bright yellow or orange color and a smooth, unblemished skin. If the skin is mottled or has any discoloration, it may be a sign that the squash is not fresh.
  • Check the stem. The stem of a good spaghetti squash should be dry and firm, indicating that it was harvested at the right time. If the stem is green or moist, it may indicate that the squash was picked too early or is not fully ripe.
  • Consider the size of the squash. Spaghetti squash comes in a variety of sizes, but for best results, look for squash that are medium-sized and evenly shaped. Larger squash can be tough and less flavorful, while smaller squash may not yield enough “spaghetti” strands for this recipe.

How To Prepare Spaghetti Squash

Spaghetti squash is a delicious and nutritious vegetable that can be prepared in a variety of ways. If you’re looking for a simple and foolproof method, try this easy recipe that yields tender shreds of slightly caramelized squash.

  • Preheat oven to 400 degrees F and line a large baking sheet with parchment paper.
  • Use a very sharp chef’s knife to cut off both ends of the spaghetti squash, then slice it in half lengthwise. Use a large spoon to scoop out the seeds and discard them. (Or wash & roast ’em up!)
  • Next, drizzle the insides of each squash half with oil and season with salt and pepper. Place the squash halves cut-side down on the prepared baking sheet.
  • Bake the squash in the preheated oven until the interiors are easily pierced through with a fork. (The exact baking time will depend on the size of your squash.)
  • Once the squash is done baking, use a fork to fluff the interiors and create “spaghetti” strands. This step is where the magic happens – you’ll be amazed at how much it resembles actual spaghetti! Spaghetti Squash With Meatballs here we come!

Quick Tip

To avoid injury, it’s essential to use a very sharp chef’s knife and a sturdy cutting board when preparing spaghetti squash. If you’re missing either, it’s recommended to microwave the squash for 3-5 minutes each to soften them enough to slice in half safely.

How To Make Spaghetti Squash with Meatballs (Tips)

  • Keep the ground turkey as cold as possible. Ground turkey is easiest to form into meatballs when it’s cold, so take it out of the fridge right when you need it and be careful not to overwork it (which will also warm it up).
  • Grate the onion. While it may be a tedious step, grating the onion will give these meatballs the best possible taste and texture. No large chunks of uncooked onions, and all the great flavor will be dispersed throughout.
  • Use Panko breadcrumbs. Panko breadcrumbs are lighter and crispier than traditional breadcrumbs, which gives these meatballs a great texture.

Tips Continued

  • Use cooking spray! When forming the meatballs, it can be helpful to lightly grease your hands with cooking spray to prevent the meat from sticking.
  • Bake the meatballs. Baking the meatballs in the oven is a healthier and more hands-off method than frying them in a pan. To ensure that they cook evenly, space them out evenly on a baking sheet and flip them halfway through cooking.
  • Use a good-quality marinara sauce. If you prefer, make your own.
  • Don’t forget to taste and season. Each component of this dish (the squash, marinara, and turkey meatballs) should be independently seasoned, but don’t forget to give everything a taste together and adjust seasonings.

Storage

Meal Prep Spaghetti Squash with Meatballs

The spaghetti squash base is a nutritious and low-carb alternative to traditional pasta, while the meatballs are a great tasty source of lean protein. Best of all, this recipe is easy to make and can be customized with your favorite marinara sauce and toppings!
Prep Time: 40 minutes
Cook Time: 1 hour
Total Time: 1 hour 40 minutes
Servings: 4 large servings

Ingredients  

Meatballs

  • 1 pound (93/7) ground turkey
  • 1 large yellow onion, peeled & grated on large holes of cheese grater (Note 1)
  • 1/2 cup Panko breadcrumbs (Note 2)
  • 1/3 cup grated Parmesan (Note 3)
  • 2 tablespoons olive oil
  • 1/4 cup finely chopped fresh parsley
  • 1/2 teaspoon each: fine sea salt & pepper
  • 1 teaspoon each: beef bouillon powder, onion powder, garlic powder, & Italian seasoning (Note 4)
  • 1 large egg
  • 2 teaspoons Worcestershire sauce

Spaghetti Squash

  • 2 medium-sized spaghetti squash
  • Olive oil, salt & pepper
  • 3 cups marinara sauce (homemade or good store bought)
  • Optional toppings: fresh Italian parsley, freshly grated Parmesan cheese

Instructions 

  • SPAGHETTI SQUASH: Preheat the oven to 400 degrees F. Line an extra-large (15x21-inches) sheet pan with parchment paper and set aside.
    Using a very sharp chef's knife and sturdy wood cutting board, cut off the stem and base of the spaghetti squash. Then, cut the squash in half lengthwise. Scoop out the seeds and discard.

  • SQUASH CONT.: Drizzle each cut side of the squash with olive oil (1 tsp per squash half) and sprinkle with salt (1/4 tsp per half) and black pepper (1/16 tsp per half). Place the squash halves on prepared pan, cut side down.
    Roast for 40-60 minutes or until fork tender (easily pierced with a fork).
    Brushing the squash with oil and seasoning with salt and pepper before roasting.
  • MEATBALLS: While the squash is roasting, prepare the meatballs. Keep the oven at 400 degrees F. Generously grease a large (unlined) rimmed sheet pan with cooking spray and set aside. Grate the onion with the large holes on a cheese grater until you have a full 1/2 cup of grated onion. Add it to a very large bowl. Gently knead the ingredients until they are integrated, being careful not to overwork the meat.
    Combining ingredients; rolling the mixture into uniform meatballs for the turkey meatball recipe.
  • MEATBALLS CONT.: Use a tablespoon measuring spoon to scoop a heaping tablespoon of the meat mixture and roll it into an even-sized ball. Repeat with all the meat, aiming to get evenly-sized meatballs. You should get around 30 meatballs. (I find it helpful to lightly grease my hands with cooking spray to make rolling the balls easier).

  • BAKE: Place the meatballs on the prepared sheet pan, spaced evenly apart. Generously spray the meatballs with cooking spray. Bake the meatballs for 18 minutes. Then, use a spatula and your fingers (careful, they're hot) to gently flip the meatballs over to the other side. Bake for another 5-10 minutes or until they are nicely golden brown and cooked through.
  • SERVE: Meanwhile, warm up the marinara sauce in a small pot on the stovetop. Once the meatballs are done baking, toss them with the warmed marinara sauce. To the squashes, fluff the interiors with a fork to make squash "spaghetti." Top the squash spaghetti with the sauced meatballs. If desired, garnish with fresh parsley and freshly grated Parmesan cheese. Add additional cracked pepper and a drizzle of olive oil to the plates if desired. Enjoy promptly!

Recipe Notes

Note 1: Onion: Grating the onion will give these meatballs the best possible taste and texture. No large chunks of uncooked onions, and all the great flavor will be dispersed throughout.
Note 2: Panko breadcrumbs: Panko breadcrumbs are lighter and crispier than traditional breadcrumbs, which gives these meatballs a great texture.
Note 3: Parmesan: It's important to use the right type of Parmesan cheese to ensure that your turkey meatballs don't end up overly salty or with an odd flavor. Avoid using shelf-stable grated Parmesan, as it doesn't have the same flavor as freshly grated cheese. Instead, grab fresh (refrigerated) grated Parmesan. Or, grab aย block of Parmesanย and grate it using a microplane.
Note 4: Don't skip the "secret" ingredients. Beef bouillon powder and Worcestershire sauce may not be traditional meatball ingredients, but they add a rich, meaty flavor that will take these turkey meatballs to the next level!ย
