How to Make It
Preheat oven to 400°F. Combine beef, breadcrumbs, egg, garlic, 1/2 teaspoon salt, Italian seasoning, and 1/2 teaspoon of the black pepper in a large bowl; shape into 24 meatballs. Arrange meatballs on a rimmed baking sheet lined with parchment paper. Bake at 400°F until cooked through, about 15 minutes.
Heat butter in a large skillet over medium. Once melted, whisk in maple syrup, mustard, curry powder, and remaining 1/4 teaspoon salt and 1/4 teaspoon black pepper. Add meatballs; toss to coat. Cook 1 to 2 minutes, stirring often. Garnish with parsley.
