Ingredients

Caramelized Onion

2 large (4 cups) yellow onions, sliced
1 teaspoon finely chopped fresh thyme leaves*
1 teaspoon white wine vinegar
1/4 teaspoon coarse ground pepper
1/8 teaspoon salt

Burger

1 1/2 pounds lean ground beef
2 tablespoons stone-ground mustard
1/4 teaspoon salt
2 teaspoons coarse ground pepper

4 onion hamburger buns

Directions

Melt butter in 12-inch skillet until sizzling; add onions. Cook over medium heat, stirring occasionally, until onions are tender and deep golden brown (35 to 40 minutes).

Stir in thyme, vinegar, 1/4 teaspoon pepper and 1/8 teaspoon salt. Continue cooking, stirring occasionally, until onions are caramelized (5 minutes).

Meanwhile, heat gas grill on medium or charcoal grill until coals are ash white. Combine ground beef, mustard and salt in large bowl; mix lightly. Shape into 4 (3/4-inch thick) patties. Sprinkle both sides of patties with pepper.

Place patties onto grill. Grill, turning once, until internal temperature reaches at least 160°F. or until desired doneness (10 to 12 minutes).

Meanwhile, grill hamburger buns until toasted (3 to 5 minutes). Fill buns with hamburgers; top each with 1/4 cup onion mixture.

*Substitute 1/4 teaspoon dried thyme leaves.

Broiling Directions: Prepare onions and patties as directed above. Heat broiler. Place patties onto broiler pan. Broil, turning once, until internal temperature reaches at least 160°F. or until desired doneness (12 to 15 minutes).

Recipe Comments & Reviews

This recipe is so simple to do, and the taste is wonderful. The stone-ground mustard works very well, and really compliments the flavors of the carmelized onions. I don't have a grill, so I just did them in a saute` pan. I did add a slice of pepperjack cheese to mine, and I think I now have a replacement for my favorite pattymelt! I made them smaller because of my diet restrictions, and they reheat very well, too. This one is a real winner and will go into my personal cookbook.
came out great and the onions give the burgers an incredible flavor
