1 ½teaspoonsground allspiceoptional (I did not use it.)
1teaspoononion powder
Salt and black pepperto taste
2tablespoonsolive oildivided
3tablespoonsunsalted butter
3tablespoonsall-purpose flour
1cupbeef broth
¼cupsour cream
Instructions
In a large mixing bowl, combine the ground beef, worcestershire sauce, breadcrumbs, eggs, allspice (if using,) onion powder, salt, and pepper. Mix until just combined.
Using a 1 tablespoon cookie scoop, portion the meat mixture and roll into a ball.
Heat a skillet over medium-high heat until hot. Add 1 tablespoon olive oil and then part of the meatballs, browning on all sides. It is not necessary to cook the meatballs all the way through. Transfer the meatballs to the slow cooker and continue browning the remaining meatballs in the remaining olive oil until they are all browned.
With all of the meatballs resting in the crock of the slow cooker, add the butter to the skillet to melt. Whisk in the flour, allowing it to cook for about 2 minutes.
Slowly whisk in the beef broth until the gravy is thick.
Notes
You can use ground turkey instead of ground beef if you would prefer.
