A few weeks ago I found a semi-forgotten 1-pound piece of chuck in the freezer, and since it was looking a little tired I decided to grind it for mushroom burgers.
Step 1: Cook and caramelize the mushrooms in butter. NEVER oil, ALWAYS butter!
Step 2: Cube and season the beef, then mix in the cooled mushrooms including the butter left in the pan. I used Lawry's Seasoned Salt, pepper, oregano and a little splash of olive oil, and the mix went into the fridge to marinate for a good 24 hours.
Step 3: Run the beef and msuhrooms through the grinder together in a single pass.
Step 4: Have a patty party! I pack them fairly tightly because they do have a tendency to be a little loose, and can sometimes break on the grill.
Step 5: Grill to the desired doneness and top with cheese if desired (I used Colby). They picked up a little soot/ash but it wasn't noticeable...oh well, sometimes things happen. And as you can see, one of the burgers did come apart a little before I added the cheese.
Step 6: Stuff face.
The advance salting and the mushrooms help keep the burger moist even when thoroughly cooked, and the mushrooms add some good flavor (which is why cooked are better than raw here). I've done this a few times (a posted one of them here some time ago) and have found that a 2:1 ratio of beef to cooked mushrooms works pretty good for me; I can really taste them and the burgers aren't overly prone to crumbling on the grill. Plus it's a great way to extend a smaller amount of meat with a fairly healthy addition!
