Method
Preparation
- Preheat your oven to 350˚F. Butter the bottom of a rimmed baking sheet.
- Heat a large skillet over medium/high heat with 1/2 Tbsp olive oil. Add the diced onion and then 2 lbs of ground beef, breaking it up.
- Season with salt, black pepper, and garlic powder. Cook until the beef is just done, then remove from heat.
- Spoon off and discard excess fat, then stir in mayonnaise.
Assembly
- Cut the buns in half and place the bottom halves on the buttered baking sheet. Line with sliced cheese.
- Spread the ground beef mixture over the cheese and cover with shredded cheddar.
- Place the top halves of the buns cut-side down over the burgers.
- Brush the tops with melted butter and sprinkle with sesame seeds.
Baking
- Bake for 12-15 minutes or until the cheese is melted and the tops are golden brown.
Notes
These sliders keep well in the fridge for 3–4 days. To reheat, pop them in the oven at 350˚F until warmed through, or use the microwave, but note it won’t restore the crispy top.
