- 1 cup beef stock
- 1 cup heavy cream
- 3 tablespoons all-purpose flour
- 1 tablespoon soy sauce
- ½ teaspoon ground black pepper, or more to taste
- ½ teaspoon dried rosemary, crushed, or more to taste
- 10 ounces frozen cooked meatballs, thawed
Whisk together stock, cream, flour, soy sauce, 1/2 teaspoon pepper, and 1/2 teaspoon rosemary in a large saucepan over low heat until smooth. Cook, stirring occasionally, until thickened, about 10 minutes.
Stir in thawed meatballs, and continue cooking until meatballs are heated through, about 5 more minutes. An instant-read thermometer inserted into the center of the meatballs should read at least 160 degrees F (71 degrees C).
Taste and adjust seasonings before serving.
