Step-by-Step Cooking Instructions
Prepare Meatball Mixture:
- Combine Ingredients: In a large bowl, mix together the ground beef, French onion soup mix, breadcrumbs, milk, egg, and Parmesan cheese until well combined.
- Form Meatballs: Shape the mixture into meatballs, roughly the size of golf balls.
Brown Meatballs:
- Heat Oil: In a skillet over medium heat, heat the olive oil.
- Brown Meatballs: Add the meatballs to the skillet and brown them on all sides. This step locks in the flavors and gives the meatballs a beautiful crust.
- Transfer to Slow Cooker: Once browned, transfer the meatballs to the slow cooker.
Caramelize Onions:
- Cook Onions: In the same skillet, add the thinly sliced onions.
- Caramelize: Cook until the onions are golden brown and caramelized, about 10-15 minutes.
- Transfer Onions: Add the caramelized onions on top of the meatballs in the slow cooker.
Make Gravy:
- Mix Broth and Sauce: In a bowl, mix together the beef broth and Worcestershire sauce.
- Pour Over Meatballs: Pour this mixture over the meatballs and onions in the slow cooker.
Cook:
- Set Slow Cooker: Set the slow cooker on low for 6-8 hours or on high for 3-4 hours, until the meatballs are cooked through and tender.
- Adjust Seasoning: Taste and adjust seasoning with salt and pepper as needed.
- Garnish: Before serving, garnish with fresh thyme.
Helpful Tips
Tip: Use a mix of ground beef and ground pork for an even juicier and more flavorful meatball.
Tip: If you prefer a thicker gravy, mix 1 tablespoon of cornstarch with 2 tablespoons of water and add to the slow cooker in the last hour of cooking.
Tip: To make this dish even more indulgent, top with a slice of Swiss or Gruyère cheese and let it melt over the meatballs just before serving.
Storage and Reheating Tips
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat gently in a saucepan over low heat until warmed through. Add a splash of beef broth if the sauce has thickened too much.
- Freezing: These meatballs freeze well. Place them in a single layer on a baking sheet to freeze individually, then transfer to a freezer-safe bag for up to 3 months. Thaw overnight in the refrigerator before reheating.
