Nothing is better than a good grilled French onion burger! This easy recipe has been in my family since I was a kid - a simple homemade ground beef burger made with dry onion soup mix seasoning & Worcestershire sauce for a flavorful, juicy & satisfying grilled burger every time! Made in less than 25 minutes. Serve 'em up plain & simple, or dress 'em up with crispy bacon, caramelized onions & a light + fluffy brioche bun. Perfect for weeknight cooking or backyard BBQs!
