Sautéed fresh mushrooms make a great burger topper ? but taste even better mixed right in. This French bistro-style burger uses ground sirloin instead of the usual ground beef. Look for it in the meat section of most grocery stores. If your store doesn’t carry it, ask your butcher to grind a piece for you.
Can’t find ground sirloin? Avoid lean ground beef and buy ground beef labelled as “medium” or “regular.” Their higher fat content produces super-flavourful and tender burgers. Some fat falls through the grate when grilling. A burger made with lean ground beef has 201 calories and 12 grams fat compared to a medium ground burger with 219 calories and 15 grams fat.
Cook mushrooms as above, then wipe pan with paper towels. Prepare burgers, then lightly coat frying pan with oil and set over medium heat. Add burgers. Cover and cook until well browned and firm when pressed, 5 to 6 minutes per side. Reduce heat to medium-low if burgers brown too quickly before they’re cooked through. Tuck into buns.
