Ingredients

• Frozen beef meatballs: I like to buy a quality brand without fillers and check for seasoning and size consistency
• Yellow onion: thinly sliced these add natural sweetness and depth try to pick a fresh firm onion for best results
• Condensed French onion soup: look for low-sodium or check labels for richer flavors
• Shredded Gruyere cheese: this gives that classic French onion melt choose a block and shred it yourself for best melting quality

Step-by-Step Instructions

Prepare the Cooker:

Lightly grease your slow cooker’s insert to prevent sticking and make cleanup easier

Layer Ingredients:

Scatter frozen meatballs into the slow cooker then top with the sliced onions Pour both cans of condensed French onion soup over everything Use a spoon to gently mix so onions and soup coat the meatballs

Slow Cook:

Set the lid on and cook on low for four hours or on high for two hours The onions should soften and sweeten while the meatballs heat through and soak up flavor

Add Cheese:

About twenty minutes before serving sprinkle the shredded Gruyere evenly over the meatballs Cover again and let the cheese melt into gooey goodness

Serve Up:

Spoon meatballs and onions with plenty of sauce over mashed potatoes toasted French bread or rice for a filling meal

Save

Gruyere is my favorite part with its nutty depth and perfect stretch over each scoop My daughter says it tastes like French onion soup and pizza had a delicious baby We still laugh about how we once ate the whole pot in one sitting on a chilly Sunday

Storage Tips

Store leftovers in a tightly sealed container in the fridge for up to three days Reheat gently in the microwave or on the stove with a splash of broth or water Add fresh cheese if you want to refresh the topping The sauce stays rich even after freezing Up to three months in the freezer works well just thaw overnight in the fridge

Ingredient Substitutions

Turkey or chicken meatballs work just as well for a lighter version If you cannot get Gruyere try sliced provolone or Swiss For a boost of flavor stir in a splash of sherry white wine or Worcestershire sauce just before serving

Serving Suggestions

Pile over creamy mashed potatoes or fluffy rice for a complete dinner For parties offer toothpicks and crusty bread rounds Toasted French bread or baguette slices mimic the essence of classic French onion soup and soak up all that rich broth
