Step 1

Preheat oven to 375 degrees F. Spray a 9x13 baking dish with cooking spray and arrange meatballs inside. Set dish aside.

Step 2

In a small bowl, whisk together brown sugar, ketchup, white vinegar, Worcestershire sauce, and spicy brown mustard until smooth.

Step 3

Pour prepared sweet and sour sauce over meatballs. If needed, gently turn meatballs to coat and ensure meatballs are spaced roughly 1-2 inches apart.

Step 4

Cover dish with aluminum foil and bake as follows: For RAW, THAWED/ROOM TEMP meatballs, bake for 30-40 minutes or until insides are no longer pink. For RAW, FROZEN meatballs, bake for 40-50 minutes or until insides are no longer pink. For COOKED, THAWED/ROOM TEMP meatballs, bake for 10-20 minutes or until heated through. For COOKED, FROZEN meatballs, bake for 20-30 minutes or until heated through. If you want the meatballs to have a browned finish, remove aluminum foil for last 5 minutes of cooking. NOTE: if your chosen meatballs have specific baking instructions, feel free to use those instead.

Step 5

Garnish finished sweet and sour meatballs with chopped parsley (optional).

Step 6

Serve as desired.
