Veggie burgers are pretty popular these days. This recipe is an oldie from the 70’s, slightly revamped. Nutty oat burgers on portobello caps.
Back in the late 70’s and early 80’s we were pseudo vegetarians. Pseudo because we’d occasionally eat seafood and sometimes chicken. One thing that we had a lot were these nutty oat burgers. We usually had them on a bun with ketchup and mustard. I decided to cut down on the carbs and have them open-faced on a baked portobello mushroom cap. There’re as tasty as I remembered and this time served with a mayonnaise, ketchup and mustard sauce.
All you do to make these is throw all the ingredients into a bowl and mix them up. I let the mixture sit for about 10 minutes before I make the patties to let all the moisture get absorbed by the oats.
I made 4 large patties from one recipe, but you could make 6 smaller ones if you’d like, or even make appetizer sized portions. You could serve them with a little sauce on top with a slice of pickle stuck on with a toothpick! Yum.
Our kids always liked these. Oat burgers made a quick lunch that they never grew tired of.
This is certainly a recipe to keep handy if you’re into a vegetarian diet.

I am now, and always have been a meat and potatoes guy, but your pictures are so appealing and make this oat burger look so darn good I want to try making them!! Maybe you should name this burger, “The Big Joe”, to rival “The Big Mac”?
I love these oat burgers, even leftover ones that are cold from the refrigerator. Be sure to grate the onion on the small holes of the grater and include the onion juice with the rest of the burger ingredients.
You need to use an oil with a high smoke point for frying, but you can try varying the flavor of the burgers by using other oils in the ingredients; I recently bought a big can of walnut oil from Costco and I’d like to see how they taste using that. Olive oil would also be a good one to try or even peanut oil.
