Cabernet-Balsamic Burgers with Sautéed Mushrooms & Onions

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

Wife loved it!

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!

This is a great recipe for burgers! I did not add the mushrooms because of an allergy but based on some of the reviews the mushrooms weren't needed. I did everything else as written. My husband thought that the onions mixed into the meat kept the burgers moist. I would serve these to company.

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!

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.

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.

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 were wonderful! I had a little less than 1 1/2 lbs. meat, so I made them into 5 patties instead of 6. The onions were great, with the red wine and balsamic; could've had done with less than 4 cups of onions, though, as we had a fair amount left over. Didn't feel the mushrooms really added that much. I used reduced fat blue cheese. The onions made this burger! Will definitely make again.

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.

wonderful, the onions were great. The wine and oil made the onions loose all the bite. The mayo sauce was excellent with the combination. I will make it again.

Another outstanding burger....
