Meatball subs are a Super Bowl staple, but ditch the roll and serve these meatballs instead. In order to ensure that meatballs stay tender and moist while baking, don’t overwork the ground turkey mixture.
Preheat the oven to 350°F and line a baking sheet with tin foil.
In a large bowl, mix the ground turkey, onion, garlic, Parmesan, Italian seasonings, crushed red pepper and egg until just combined. Roll the mixture into golf ball-sized pieces, and place on the baking sheet 2 inches apart.
Bake for 30 minutes, flipping the meatballs halfway.
While the meatballs are baking, make the dipping sauce: in a large saucepan, heat the oil on medium-high. Saute the onion and garlic until softened, stirring occasionally, 10-12 minutes. Add the crushed red pepper, Italian seasonings, tomato sauce, salt and pepper. Bring to a boil, then simmer for 20-25 minutes, until the sauce has thickened slightly.
Once the meatballs are done, place toothpicks in each. Serve with the dipping sauce.
