Step 1: In a large bowl, combine the ground meat, finely chopped onion, minced garlic, breadcrumbs, egg, milk, salt, pepper, ground allspice, and nutmeg. Mix thoroughly until all ingredients are evenly incorporated.

Step 2: Using your hands, shape the mixture into small, uniform meatballs—about 1 inch in diameter. Aim for consistency to ensure even cooking.

Step 3: Heat the butter and olive oil in a large skillet over medium heat. Once the fat is hot, add the meatballs in batches, ensuring not to overcrowd the pan. Fry until all sides are nicely browned, about 5-7 minutes per batch.

Step 4: Remove the browned meatballs from the skillet and set aside. In the same skillet, sprinkle the flour over the remaining fat and stir continuously to form a roux. Gradually pour in the beef broth, stirring constantly to avoid lumps.

Step 5: Bring the mixture to a simmer, then slowly stir in the heavy cream. Allow the sauce to thicken, then gently return the meatballs to the skillet. Let them simmer in the sauce for another 10-15 minutes until cooked through and tender.

Step 6: Taste and adjust seasonings if necessary. Garnish with freshly chopped parsley before serving. Enjoy your homemade swedish meatballs recipe with your favorite sides!
