Ingredients:
- 1 pound (454g) ground beef (80/20 blend recommended)
- ½ cup (60g) panko breadcrumbs
- ¼ cup (60ml) milk (whole or 2%)
- 1 large egg, lightly beaten
- 2 tablespoons (30ml) finely chopped onion
- 1 teaspoon (5ml) garlic powder
- ½ teaspoon (2.5ml) salt
- ¼ teaspoon (1.25ml) black pepper
- 2 tablespoons (30ml) vegetable oil, for browning
- 1 tablespoon (15ml) vegetable oil
- ½ cup (100g) chopped onion
- 1 clove garlic, minced
- 1 cup (240ml) chicken broth
- ½ cup (120ml) ketchup
- ¼ cup (60ml) apple cider vinegar
- ¼ cup (50g) packed brown sugar
- 2 tablespoons (30ml) soy sauce (low sodium)
- 2 tablespoons (24g) cornstarch
- 2 tablespoons (30ml) cold water
- Optional: 1 (8 ounce/227g) can pineapple chunks, drained
- Optional: 1 bell pepper (any color), cut into 1-inch pieces
- Optional: 1 tablespoon sesame oil
Instructions:
- Combine all meatball ingredients (except the oil) in a large bowl. Gently mix until just combined. Don't overmix!
- Cover the meatball mixture and refrigerate for at least 30 minutes. This helps them hold their shape.
- Roll the meat mixture into 1-inch meatballs.
- Heat vegetable oil in a large skillet over medium-high heat. Brown the meatballs on all sides. Don't worry about cooking them all the way through at this stage. Remove meatballs from the skillet and set aside.
- Add oil to the same skillet, if necessary. Sauté onion until softened, then add garlic and cook until fragrant.
- Whisk together chicken broth, ketchup, apple cider vinegar, brown sugar, and soy sauce in the skillet. Bring to a simmer.
- In a small bowl, whisk together cornstarch and cold water to form a slurry. Slowly pour the slurry into the simmering sauce, whisking constantly, until the sauce thickens. This is the sweet n sour sauce for the meatballs.
- Add the browned meatballs to the sauce. If using, add pineapple chunks and bell peppers.
- Reduce heat to low, cover, and simmer for 20 minutes, or until meatballs are cooked through and the sauce has thickened further. Stir occasionally.
- Drizzle with sesame oil (optional). Serve hot over rice or noodles. Garnish with chopped green onions or sesame seeds if desired.
