The best burger I have ever eaten was at a little place in Missouri called Agrario. There my taste buds drowned in delight as I dug into a wonderful concoction of grass-fed beef, bacon, swiss cheese and the most surprising ingredient of all time…blueberries! I’m no longer in Missouri, and unfortunately Agrario isn’t there anymore either. Coincidence? Maybe not. Even after many years I have been having a mad craving for this burger so I decided to try to recreate it. Judging from the enthusiastic yummy noises in my house, I call this a resounding success!
Blueberry Bacon Swiss Burgers
1 pound ground sirloin
1 cup fresh or frozen blueberries, pureed
Splash of red wine (about 1/4 cup)
Salt & pepper
Tiny pinch of sage
1-2 tsp. butter, cut into pieces
Fry bacon until crisp. Remove from pan and set aside. Discard bacon grease and wipe out pan. Form ground beef into 3 or 4 patties. Sprinkle with sea salt and freshly ground pepper. Set aside. Heat pan over medium high and add patties to the pan. Cook about 4 minutes per side until burgers are done to your liking. Slice rolls in half and toast under the broiler in the oven until lightly browned. Add cheese to tops of burgers and set aside.
If there is a lot of grease in the pan, discard almost all of it. If you’ve used lean beef there probably won’t be much. In hot pan, add pureed blueberries and wine to hamburger drippings, scraping up any little bits as you go. Stir and bring to a boil. Add salt, pepper and a little pinch of dried sage.
Boil and stir a few minutes until thickened and reduced. Remove from heat and stir in butter until melted. Build burgers by putting a little sauce on the bottom bun, then placing burgers on the bun cheese side down, top with more blueberry sauce and bacon.
