A sweet, rich onion topping enhances the umami, or savory flavor, of these burgers. Look for 93% lean ground beef, which is enough fat to keep the burgers moist and tender, and lean enough to keep them healthy.
Work the burgers as little as possible to prevent them from becoming dry. Form them into nice even patties that hold together, but try not to compact the meat too much. Also, indent the top with your thumb. Burgers puff when they cook, and that indentation keeps the top nice and flat — which helps the bun stay on!
Serve this meal with:
The Cabernet onion jam really made this burger special, but still simple and tasty. I liked how the wine and balsamic vinegar added a bit of tang and a beautiful color to this tasty condiment. The onion jam can be made a day or two ahead, and it would be delicious on turkey burgers or other sandwiches if you have extra.

Beef Burgers with Cabernet Onion Jam
extra-virgin olive oil
very thinly sliced red onion (from 2 medium red onions)
Cabernet Sauvignon wine
1 1/4 pounds
lean ground beef
thinly sliced Gruyere cheese
(2-ounce) sourdough or Kaiser rolls
Heat the oil in a large skillet over medium heat. Add the onion, sugar, and 1/4 teaspoon of the salt and cook, stirring occasionally, until the onion is very soft, about 15 minutes. Add the wine and vinegar and cook until the liquid is nearly gone, 12 to 14 minutes longer (25 to 30 minutes total). Cover and set aside.
Prepare a grill for direct-heat cooking (400° to 500°F). Brush the grates lightly with oil.
Mix the beef, remaining 1/2 teaspoon salt, and pepper with a fork; form into four 3/4-inch-thick patties. Press your thumb in the center of each burger to form an indentation. Grill the patties 4 to 5 minutes, turn and grill another 4 minutes, and top with the cheese. Cook until the cheese is melted and the burger is cooked to desired degree of doneness (160° for medium).
Place the burger on the bottom half of the roll; top with the onion jam and close the sandwich.
