Gourmet Hamburger Patties: Red Onion Burger

18 minutes
9 hamburger patties
Ah, hamburgers—everyone loves the mouthwatering char-grilled goodness. But with that amazing taste comes “hamburger hands”...that dreaded sticky mess from making the patties. Not to mention portion size and prep time. Here’s the perfect solution: Create delicious gourmet hamburgers in a Ziploc® brand bag beforehand, then score the bag for individual portions and freeze for later.


  • 2

    pounds ground beef

  • ½

    cup red onion, peeled and diced

  • ¼

    cup fresh parsley, chopped

  • 2

    tbsp Worcestershire sauce

  • 1

    tbsp Dijon mustard

  • 1

    tsp kosher salt

  • ½

    tsp ground black pepper


Make ahead:

  • 1 Place all ingredients in a gallon size Ziploc® brand freezer bag. Seal, pressing all the air out, and mix thoroughly by kneading the bag with your hands.
  • 2 Lay the bag on a flat surface and press on it gently to even out the hamburger meat. Then, using a chopstick or ruler, score the bag, making 9 squares. Freeze or use immediately.

Ready to eat:

  • 1 Heat a charcoal or gas grill to medium-high.
  • 2 Break the patties along the score marks. Take out however many patties you need and keep the rest in the bag.
  • 3

    Place hamburger patties on the grill and grill for 4 minutes a side for a medium doneness. Serve on hamburger buns.
