These Slow Cooker French Onion Meatballs Are Easy and Cheesy
French onion meatballs combine all the flavors and ingredients found in a classic French onion soup, packing them into a hearty main dish or appetizer sure to impress friends and family.
Ingredients in French Onion Meatballs
I doubled down on the onion flavor by adding dry onion soup mix to the meatballs, and the condensed French onion soup ensures a rich, flavorful broth, even after a few hours in the slow cooker. The onion-forward broth, melty cheese, and toasted baguette slices mimic the iconic soup.
Use a Slow Cooker for a Nearly Effortless Dish
The slow cooker makes this fabulous dish nearly effortless. There's no need to caramelize the onions on the stovetop, which can take up to 1 hour of cooking and stirring. In the slow cooker, the seasoned onions release their juices and soften beautifully, freeing you to attend to other tasks.
Tips for Making French Onion Meatballs
Slicing the onions—A mandoline or food processor with a slicing disk are excellent ways to slice the onions quickly and ensure uniform slices.
Avoid oversalting—If the broth is salty, you might not have to add more. Wait until the sauce is nearly done, then taste it and add salt if needed.
Lean is best—Choose lean ground beef with a ratio of lean to fat of 85/15 or 90/10.
Which size slow cooker to use—A 6 to 7-quart slow cooker is ideal. If your slow cooker is smaller, stir the onions every 30 to 45 minutes to ensure even cooking.
