• Step 1: In a large skillet or Dutch oven, melt the butter over medium heat. Add the frozen meatballs and cook, stirring occasionally, until heated through, about 5-7 minutes.
• Step 2: Sprinkle the flour over the meatballs and stir to coat. Cook for 1-2 minutes, stirring constantly, to create a roux and thicken the sauce.
• Step 3: Slowly pour in the beef broth, whisking continuously to prevent lumps. Bring the mixture to a simmer and cook, stirring occasionally, until the sauce has thickened, about 5-7 minutes.
• Step 4: Reduce the heat to low and stir in the heavy cream, Worcestershire sauce, garlic powder, onion powder, and nutmeg. Season with salt and black pepper to taste.
• Step 5: Simmer the meatballs in the creamy sauce for an additional 5-10 minutes, until the sauce has reached your desired consistency.
• Step 6: Serve the Swedish meatballs warm, over mashed potatoes, egg noodles, or with your favorite sides.
