Step 1

To a large skillet over medium heat, add a tablespoon of olive oil. Add the chopped onion and cook until soft and translucent; about 3 minutes.

Step 2

In a large mixing bowl and with a wooden spoon or clean hands, combine ground beef, ground pork, eggs, breadcrumbs, cooked onion, salt, pepper and allspice. Mix just until combined.

Step 3

Shape into meatballs with your hands, using a regular cookie scoop for small meatballs, or an ice cream scoop for large meatballs.

Step 4

Melt butter in the skillet over medium heat. Add meatballs in batches, turning often to brown on all sides. When cooked through (about 4-5 minutes), transfer to a paper towel lined plate.

Step 5

To make the gravy, add ¼ cup butter to the skillet to melt. Whisk in flour and cook until golden; about 2 minutes. Gradually add beef broth, Worcestershire, and half and half, whisking constantly, until thickened.

Step 6

Stir in sour cream and season with salt and pepper to taste.

Step 7

Add meatballs back to the skillet to ensure they are heated through. Garnish with chopped parsley and serve immediately with mashed potatoes or egg noodles on the side.
