Blended Mushroom Burger with Provolone & Sautéed Mushrooms

Umami defined, from

The tastes of sweet, salty, bitter and sour are familiar, but there is a fifth taste we can perceive with our tongue. Called umami, its taste has been described as rounded, rich and savoury. Of the five tastes, umami (a Japanese-coined name) is our favourite to think about when cooking.

After making and most enthusiastically enjoying these blend & extend mushroom beef burgers, I understand what umami means. I’ve now tasted it. Rounded, rich and savoury are not usually descriptives I’d use for a burger, but in this case, they’re spot on. Spectacular!

An absolutely ingenious idea, blending mushrooms into the beef mix is smart in every which way you look at it! It adds nutrition, it adds flavour and it extends the meat. Blend. Extend. Feast! You may be thinking it sounds a bit weird, but it really is a clever way to sneak some veg into a food that everybody already loves.

You really can’t tell there are mushrooms in the burger! They’re minced and cooked a little before being added to mix. If you’re a mushroom lover like me, sauté more mushrooms for a topping! If not, just load on more veg like tomato, lettuce and cucumber. Don’t forget the homemade tomato ketchup and zesty homemade mustard!

  • 200 grams Ontario mushrooms
  • 450 grams medium ground beef (1 lb.)
  • 1/4 small onion grated (about 2 tablespoons)
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon Kosher salt
  • 1/4 teaspoon fresh ground pepper
  • cheese slices: provolone , swiss, cheddar, etc

to serve:

  • burger buns
  • tomato, lettuce, cucumber, onions
  • mustard, ketchup, relish
  • *optional: sautéed mushrooms


  1. In a food processor, finely mince the mushrooms. In a skillet over medium heat cook the mushrooms for 4 - 5 minutes, stirring occasionally. Set aside to cool.
  2. In a large mixing bowl add mushrooms, and all remaining ingredients. With very clean hands, mix gently to combine.
  3. Form into 4 large patties, and set aside. (They will be quite big, make 6 smaller burgers if you prefer!)

  4. On a barbecue or in a large skillet on medium heat, add the burgers, giving them a good sprinkle of salt & pepper. Cook for about 5 minutes, then flip and season the other side. Cook for another 5 or so minutes, until lovely, caramelized and cooked through, adding cheese during the final couple minutes of cooking.
  5. Serve on your fave buns, adding condiments or passing them on the side.
