Total Time: 3 hours 40 minutes

What You Need

• 26 oz bag of frozen beef meatballs (go with homestyle or plain)
• 1 large yellow onion, thinly sliced
• 2 cans (10.5 oz each) condensed French onion soup
• 1 cup shredded Gruyère cheese (or provolone if that’s what you have)

How to Make It

1. Dump in the meatballs
   No need to thaw. Just pour them straight into your slow cooker.
2. Add onion and soup
   Slice up the onion, toss it in, then pour in the soup. Give it a quick stir.
3. Cook it low and slow
   Cover and cook on LOW for 3–4 hours or HIGH for 1–2 hours. Stir once or twice if you can.
4. Add the cheese
   About 20 minutes before dinner, sprinkle the cheese on top. Cover it again and let it melt.
5. Serve it up
   Great over mashed potatoes, toasted bread, or rice. Add a green veggie on the side if you’ve got one.

Quick Tips

• Skip Italian-style meatballs. The seasoning doesn’t mix well with the French onion flavor.
• Gruyère is classic, but if it’s hard to find or pricey, provolone or Swiss are totally fine.
• Pre-sliced frozen onions are a solid shortcut if you’re tight on time.

Make Ahead and Leftovers

• You can prep everything (except the cheese) the night before and refrigerate it. In the morning, just start the slow cooker.
• Leftovers keep in the fridge for 4–5 days.
• Freeze extras for up to 3 months. Thaw overnight in the fridge and reheat in the microwave or slow cooker.

Recipe Variations

• Want to use homemade meatballs? Go for it. Just sear or partially bake them so they stay together in the slow cooker.
• Add a splash of white wine or sherry for extra depth.
• Works with turkey or chicken meatballs if you prefer something lighter.
