Ingredients
- 2 tablespoons butter
- 2 Vidalia onions, sliced
- 2 Granny Smith apples, diced
- 2 pounds 80 percent lean ground beef
- 1 teaspoon salt
- 1 teaspoon black pepper
- 2 tablespoons chopped fresh thyme leaves
- 1/2 cup Dijon mustard
- 1 egg
- 1 cup seasoned bread crumbs
- 4 large crusty rolls, split
- 4 tablespoons mayonnaise
- 1 cup blue cheese
Directions
Melt butter in skillet over medium-high heat. Add onions to hot pan and begin caramelizing, stirring occasionally. After 4 minutes or so, add apples to the onions and continue to cook until onions are golden brown, about 6 more minutes. Remove from heat when done.
While onions and apples are cooking, blend together in a large bowl the ground beef, salt, pepper, thyme, Dijon, egg, and bread crumbs. Be sure ingredients are well incorporated, but don't over work. Form mixture into 4 good-sized patties. (hint: If you create a concave burger, with the center thinner than the edges, when it cooks the burger won't swell up to look like a meatball, but will remain flat and patty-like)
Heat grill to medium-high heat.
Place burgers on grill and cook about 10 minutes per side, or until cooked through. As burgers are finishing (after the first flip), spread mayonnaise on both cut sides of each split roll. Place rolls on grill, mayonnaise side down, to toast for about 1 minute, or until golden.
Place each burger on the bottom half of a toasted roll. Top with about 1/4 cup of blue cheese, then with a generous scoop of the caramelized onion and apple mixture. Cover with the roll and serve.

I agree that the portion for these was a little large. I only made 1/2 the recipe and still had way more than I needed. We did not like the blue cheese at all. I hardly put any on my burger, but it still managed to overpower the taste. I tried both a burger with, and a burger without the blue cheese. The favorite at our table seemed to be without the cheese.

All the grown ups enjoyed this burger. It's very savory with the onions, apples and blue cheese. I probably won't add the bread crumbs next time because I didn't like the meat-loaf texture it gave the patties. All in all a really good and different burger though.

I'm giving this 4 stars for a few reasons. We really liked the burgers, but like the last reviewer, reduce the time to about 1/2 of the recipe. My husband and I made these together and halved the recipe b/c we only wanted two burgers. Lo and behold, halving the recipe still resulted in ridiculously large portions, so we made 4 1/4 burgers instead of 2 1/2 pound burgers. Don't be afraid to be generous with the blue cheese, it tends to get drowned out in the rest of the flavors. We'll make this again.
