1/2 cup Butter [melted]
1/2 cup Sour Cream
3/4 cup Milk {more as needed}
1/4 teaspoon Salt
1/8 teaspoon Pepper
1 MEATBALLS
1 pound Ground Beef
1/3 cup Oats
1/4 cup Milk
2 tablespoons Worcestershire Sauce
1 Egg
1/4 Onion [minced]
1 teaspoon Garlic [minced]
2 tablespoons Olive Oil
1/2 cup Ketchup
2 tablespoons Water
1 package French Onion Soup Mix
Preparation
Make the mashed potatoes: Wash and dice the potatoes into 1" pieces, then place in a large pot and cover with 1" of water. Bring to a boil over high heat, then reduce to low. Simmer, uncovered, until potatoes are very tender, 20 minutes. Remove potatoes from the water with a slotted spoon and place in a large bowl. Add butter, sour cream, and milk to the bowl and mash potatoes. Season with salt and pepper, adding more milk as needed
Make the meatballs: Preheat oven to 400º. In a large mixing bowl, add ground beef, oats, milk, Worcestershire sauce, egg, onion, and garlic and combine well with your hands. Form mixture into 12 balls, each 1 1/2" in diameter. In a large, oven-safe skillet over medium heat, heat oil, add meatballs, and cook for 3 minutes per side
Meanwhile, whisk together ketchup, water, and onion soup mix. Spoon the mixture over the browned meatballs and bake, 20 minutes. Serve meatballs over mashed potatoes
