Ingredients Overview

These meatballs combine lean ground turkey, finely shredded zucchini, a beaten egg, and grated parmesan for flavor and binding — no breadcrumbs required, making this a naturally low-carb option. Turkey is an excellent lean protein choice, and zucchini adds moisture along with a boost of vitamin C and potassium according to Harvard’s School of Public Health. They simmer in a simple, savory marinara sauce that infuses flavor as they cook.

Step-by-Step Instructions

1. In a large bowl, combine ground turkey, shredded zucchini (squeezed of excess moisture), egg, parmesan, garlic powder, salt, and pepper.
2. Mix gently until just combined — avoid overmixing to keep the meatballs tender.
3. Roll the mixture into golf ball-sized meatballs (about 20-24 meatballs).
4. Pour half of the marinara sauce into the bottom of the crockpot.
5. Arrange the meatballs in a single layer, then pour the remaining sauce over the top.
6. Cover and cook on LOW for 5-6 hours, or HIGH for 3 hours, until the meatballs are fully cooked through.
7. Garnish with fresh basil or parmesan before serving.

Meal Prep & Storage Tips

Store in airtight containers in the refrigerator for up to 4 days. These meatballs freeze exceptionally well for up to 3 months — freeze in individual portions with sauce for easy grab-and-go meals. Reheat in the microwave or on the stovetop over medium-low heat.

Variations & Substitutions

Swap ground turkey for lean ground chicken or beef if preferred. For a dairy-free version, omit the parmesan or use a dairy-free alternative. Serve over zucchini noodles, spaghetti squash, or whole wheat pasta depending on your carb preferences.

FAQ

Why do you add zucchini to meatballs?
Shredded zucchini adds moisture to lean meats like turkey, which can otherwise dry out easily. It also sneaks in extra nutrients without altering the flavor significantly.

Do I need to squeeze the water out of the zucchini first?
Yes — squeezing out excess moisture (using a clean towel or cheesecloth) helps the meatball mixture hold together better and prevents overly wet meatballs.

Can I bake these meatballs instead of using a crockpot?
Yes, though the crockpot method keeps them especially moist and infuses more flavor from the simmering sauce over time.

Conclusion

These Crockpot Turkey Zucchini Meatballs prove that lean, low-carb meal prep can still be comforting and satisfying. Moist, flavorful, and easy to batch cook — they’re a recipe you’ll turn to again and again.
