Step 1

Bring a large pot of lightly salted water to a boil. Add noodles and cook, stirring occasionally, until tender yet firm to the bite, 10 to 12 minutes. Drain.

Step 2

Heat oil in a large skillet over medium-high heat. Add onion and garlic; cook and stir until onion is almost soft, about 3 minutes. Reduce heat to medium and pour in cream of mushroom soup, milk, and Worcestershire sauce; stir until blended.

Step 3

Stir meatballs into the skillet. Reduce heat to low and simmer, covered, until tender, 35 to 40 minutes. Stir in sour cream, salt, and pepper. Cook until flavors combine, about 2 minutes.

Step 4

Serve meatballs over noodles.
