This sweet and savory mouth-watering Guinness burger recipe inspired by St. Patrick's Day features a flavorful Guinness reduction glaze, crispy onion rings, and super melty sharp white cheddar cheese. Celebrate with this festive St. Paddy's Day burger whether you're Irish or not!
Begin by preparing the Guinness Glaze (see directions below).
Grill the burger patties and prepare the onion rings. Once the burgers are almost finished, add the cheddar cheese to melt.
Assemble your Guinness burgers: transfer patties to potato buns and top with 1 to 2 onion rings and a drizzle of Guinness Glaze.
Serve with your favorite side, a cold Guinness, and enjoy!
Guinness Glaze
Add Guinness and brown sugar to a small saucepan. Stir to combine and bring to a boil.
Reduce heat and simmer until thickened and reduced by about two-thirds, about 20 to 30 minutes. Stir occasionally and watch for bubbles, lowering heat if it starts bubbling too much.
Transfer glaze to a small bowl and refrigerate for at least 5 minutes before drizzling over burgers.
