Grilled cheeseburgers get an irresistible upgrade with creamy blue cheese and caramelized onions spiked with jammy red wine and tart-sweet vinegar. A portion of the tender onions are mixed into the patties to help keep the lean beef moist.

How to Make It

Step 1

Heat a large nonstick skillet over medium-low heat. Add 2 teaspoons olive oil to pan; swirl to coat. Add onion and thyme; cook 17 minutes or until golden and very tender, stirring occasionally. Increase the heat to medium-high; add wine, vinegar, and 1/4 teaspoon salt. Cook for 6 minutes or until the liquid almost evaporates, stirring occasionally. Remove onion mixture from pan.

Step 2

Wipe pan clean with paper towels. Heat pan over medium-high heat. Add the remaining 3 teaspoons oil to pan; swirl to coat. Add mushrooms and 1/4 teaspoon salt; sauté for 8 minutes or until mushrooms brown and liquid mostly evaporates.

Step 3

Preheat grill to medium-high heat.

Step 4

Coarsely chop 1 cup onion mixture, and stir chopped onion mixture into beef. Divide the beef mixture into 6 equal portions, gently shaping each into a 1-inch-thick patty. Press a nickel-sized indentation in center of each patty. Sprinkle the patties with remaining 1/4 teaspoon salt. Place patties on a grill rack coated with cooking spray, and grill for 4 minutes on each side or until done.

Step 5

Combine mayonnaise, blue cheese, and garlic in a bowl, and mash well with a fork. Spread the top halves of buns evenly with mayonnaise mixture. Arrange 1/4 cup arugula on bottom half of each bun; top each bottom half of bun with 1 patty, about 2 tablespoons remaining onion mixture, about 1/4 cup mushrooms, and top half of bun.

These burgers are amazing. I followed the recipe exactly and would not change a thing! We made them one night and then made them for friends a few nights later. I am still thinking about them!

These are great--household loved them! I didn't have enough onions to go into the beef and on top, so I left out the onions as topping. Otherwise followed the recipe. I'm not a fan of mushrooms myself but even I enjoyed them on this burger. Served these alongside Alexia's Sweet Potato Puffs. I will definitely make these again.

These burgers were super delicious, I would serve these to guests. I sautéed the mushrooms with a clove of garlic; we thought the mushrooms added a lot of flavor. I made a watermelon, cilantro, red onion and jalapeño salad to accompany these burgers-a perfect side to a delicious summer meal.

Really delicious, will make again. Onions, mushrooms, and mayo were all great. Didn't put the arugula on the burgers, but didn't miss it either. Overall, it was a hit.

I've always wanted to try making my own burgers and I was looking for something different. These burgers were amazing! I used regular ground beef and regular onions, also I did not make the mayo dressing that went on top. I was serving a large crowd and did not want to dictate what went on everyone's burger. Everyone raved about the burgers and those that added the extra onions on top loved them! This was a great burger and I now have an excellent burger reputation!

Absolutely delicious! My son wasn't exactly keen on eating it but I thought it was great although I skipped the roll.

Sweet burger, pretty good with restaurant-style presentation. Prepped the onions, mushrooms & mayo spread earlier in the afternoon. We started with 4c of raw onion but somehow after cooking ended up with less than the 2c we were supposed to have, so slightly reduced the amount added to the beef. Nice to brown the mushrooms, good flavor. Subbed thin-sliced mixed greens for the arugula, otherwise made to recipe. Grown-up burgers, would be great for guests.
