My husband Kirk went crazy over this meal. He loves onion burgers but the mushroom gravy and caramelized onions really top it off. And it’s much better for you than making milk gravy out of the drippings.
If you don’t have onion soup you can use dried onions (2 Tlb) and beef bullion.
Evenly mix the onion soup into the hamburger. Make into patties and fry in a frying pan until cooked through. Would be good to make burgers on the grill too!
Make my Mushroom Gravy recipe to have on top of burgers. And make my Caramelized Onion recipe to put on top of the gravy.
