- 2 beef burgers
- 3 ounces Guinness (or any dark beer)
- 1/4 cup diced red onion
- 1 tsp olive oil
- dash of salt
- Dice red onion and place in food processor with Guinness, olive oil and salt. Puree until smooth and liquidy.
- Liberally baste burgers on one side with marinade. I use a fork to poke holes in the burger so the beer mixture seeps in a bit more.
- Place burgers on grill, marinade side up. Grill 2-3 minutes, flip, and brush other side liberally with remaining marinade. Discard any leftover marinade. Continue cooking until burgers are done to your liking.
