French Onion Meatballs

French Onion Meatballs- tender beef meatballs are covered with melted gruyere cheese and a caramelized onion gravy. In addition, there’s toasted baguette slices to soak up all the flavor.

How To Serve French Onion Meatballs

Best served over mashed potatoes, white rice or egg noodles. This is a hearty, filling meal and I like to serve it with a garden salad with Creamy Italian Dressing.

Bake The Meatballs

I like to cook the meatballs in the oven and then add them to the sauce. I love that cooking meatballs in the oven frees up your hands to work on other things. If you bake them under high heat, they still get nicely browned on the exterior.

Note: The meatballs can be baked a day in advance.

Add Extra Flavor

One of my favorite parts of French Onion Soup is sherry. I haven’t added it to this recipe, but you could definitely add a splash or two to the sauce. Use a dry sherry, not a dessert sherry.

Substitute Ground Turkey or Chicken

Instead of using ground beef, you can use ground turkey or ground chicken. Don’t use ground meat that is too lean. Some fat content will keep the meatballs tender and juicy.

Take Your Time Caramelizing The Onions

To get the onions nicely caramelized, the heat must be fairly low and it should take at least 20 to 30 minutes. This slow process will really bring out their sweet flavor. If they haven’t sweetened to your liking, you can add a pinch of sugar.
