Add these umami mushroom beef burgers to your next bbq night. The flavors are out of this world and will be a standout burger, or fantastic protein topper for your next meal!
In a large skillet heat to medium-high heat and add the oil. Once hot, add the diced mushrooms and 1/4 tsp sea salt. Saute until the mushrooms are soft and release their liquid, about 5-7 minutes.
Add the mushrooms to a large bowl to cool slightly, then and add the remaining ingredients. Mix, then shape into 4 patties. [TIP: Add a small thumb size indent in the center of the patty – this helps the burger to cook up more flat than round as it shrinks]
Heat grill pan, cast iron skillet or bbq to medium-high heat. Add patties, cook on 1 side for 4-5 minutes, flip and finish 3-4 minutes on the second side. Depending on how thoroughly you like the the burgers cooked adjust the cooking time.
If you choose to freeze the patties, freeze individually after shaping while they are uncooked. Cook the patties directly from frozen. The cooking time will increase by a few minutes.
