Prepare your potatoes. I used two small Yukon Gold potatoes that I baked, then mashed with a fork. You could also use leftover mashed potatoes.
Place all of the ingredients for the meatballs in a large bowl and use your hands to mix it all together. Pour the olive oil in a large skillet. Preheat the oven to 375 degrees F.
Form the meat mixture into meatballs and place them in the skillet with the olive oil. Cook over medium heat, turning so that they are browned on all sides.
Once the meatballs are browned, transfer them to a ceramic baking dish. Add ½ cup water, and bake at 375 degrees F until they are cooked through - about 15-20 minutes. The meatballs should reach an internal temperature of 165 degrees.
Once the meatballs are almost done baking, use your spiralizer to make your zucchini into zoodles. (If you don't have a spiralizer, you can just thinly slice your zucchini.
Place the zoodles into a pot with the olive oil, garlic, and lemon juice. Cook over medium heat for about 5 minutes, stirring often, until the zoodles are tender and bright green.
Once the zoodles are cooked, season with salt and pepper. To serve, place some zoodles on each plate and top with meatballs. Garnish with fresh basil if desired.
Notes
Store leftovers in the refrigerator. They should stay fresh for about 3 days.You can also serve these meatballs with rice, pasta, or mashed potatoes if you prefer.
