Patty Melts with Grilled Onions
Juicy hamburgers are packed with flavor from the sweet onions and spicy mustard. For a sharper onion taste, use white or red onions in place of Vidalias.
How to Make It
Step 1
Arrange onion slices on a plate. Drizzle vinegar over onion slices. Heat a large grill pan over medium heat. Coat pan with cooking spray. Add onion to pan; cover and cook 3 minutes on each side. Remove from pan; cover and keep warm.
Step 2
Heat pan over medium-high heat. Coat pan with cooking spray. Divide beef into 4 equal portions, shaping each into a 1/2-inch-thick patty. Sprinkle patties evenly with salt and pepper. Add patties to pan; cook 3 minutes on each side or until done.
Step 3
Spread about 1 teaspoon mustard blend over 4 bread slices; layer each slice with 2 tablespoons cheese, 1 patty, 2 onion slices, and 2 tablespoons cheese. Spread about 1 teaspoon mustard blend over remaining bread slices; place, mustard side down, on top of sandwiches.
Step 4
Heat pan over medium heat. Coat pan with cooking spray. Add sandwiches to pan. Place a cast-iron or other heavy skillet on top of sandwiches; press gently to flatten. Cook 3 minutes on each side or until bread is toasted (leave cast-iron skillet on sandwiches while they cook).

I make these on sour dough bread and use Swiss cheese. They are delicious.

My husband and I really love this recipe and I make it often. Cooking the onions in the balsamic gives it a really good flavor as well as the mustard.

Pretty good. Made to recipe using marble rye and cooked all on the George Foreman. Only change was to sprinkle the patties with Montreal steak seasoning instead of s&p. Supereasy dinner. Served with baked beans & corn on the cob.

Hits the spot!! Undercooked the meat slightly so it finished when toasting. Used the George Foreman to get that panini-press effect. Love the crunch of the rye. Great way to use the vidalia onions that the Shriner's sell.

The picture of the sandwich with grill marks comes from a grill pan not a frying pan. I used a grill pan and what a mess. Nothing special.

These turned out great. They weren't greasy and the onions were really good. The cast iron pan worked great and made the bread crispy and perfect.

I thought this was okay, but my family seemed to enjoy it. I added a beef steak tomatoe slice; that I grilled quickly after grilling the onion. I used sourdough as another reviewer did, b/c I don't care for rye bread.

Made as stated except I used just dijon mustard instead of the blend. Used a really good jewish rye. I've always had a soft spot for these in restaurants. No more sloppy ones dripping with grease. This is easy and excellent.
