This diner classic gets a makeover by replacing some of the ground beef with finely chopped portobello mushrooms, which add moisture and flavor. We like a smear of pickle relish on top, but you could try chutney, mustard or hot pepper relish in its place.

  • Gently mix beef, mushrooms, breadcrumbs, Worcestershire, thyme, salt and pepper in a medium bowl until combined. Shape into 4 patties and place on the prepared pan. Broil until cooked though, 4 to 6 minutes per side.

  • Meanwhile, toast bread. Rub each slice of toast with garlic.

  • Place 1 patty on each piece of toast, top each with 2 teaspoons relish and cover with a slice of cheese. Remove foil and place the sandwiches on the pan; broil until the cheese is just melted, 30 to 60 seconds.

Juicy and so flavorful! This is one my absolute favorite go-to recipes. I'm not a fan of relish but it works so beautifully here. They balance is wonderful: crispy garlicky bread juicy meaty patty tangy relish and just a little gooey cheese. I could seriously eat these every day. YUM. Pros: juicy flavorful filling meaty Read More

These are delicious! I think I put a little too much fresh Thyme in mine so watch for that. Also I agree with the PP I ended up with full and thick burgers so there was definitely enough meat mixture to make 5 patties. Excellent taste and even my PICKY toddler loved it!! Read More

Very easy to make and very good. I can taste the mushrooms but that's good because I'm fond of them. Both of my fussy boys (ages 4 and 6) loved eating the burgers. Read More

This was so easy to make and the burgers were so juice. I did not use the relish either and just served it with a slice of reduced fat swiss cheese. Read More

This was really good I thought. My husband is more into plain grilled burgers so he didn't care for it much; this was sort of a fancy flavored burger (the thyme and Worcestershire sauce are prominent). As far as the mushrooms go you can't tell much that they're in there as far as flavor/texture but they sure make a moist burger! I certainly would not spend the extra money on portobello mushrooms again. If I make this again I will buy the less expensive button mushrooms. Also I put grilled onions instead of the relish for a more authentic patty melt! Read More
