  3. Step 3: Butter the insides of 4 burger buns with 2 tbsp softened butter.
  4. Step 4: Grill the patties for about 4 minutes per side, placing 1 slice smoked cheddar cheese on each during the last minute to melt.
  5. Step 5: Toast the buttered buns on the grill for 1-2 minutes until golden.
  6. Step 6: Spread 1 tbsp mayonnaise on each bun bottom, add a lettuce leaf, a cheddar-topped beef patty, 1 tomato slice, and a generous amount of pickled red onions. Cap with the top buns and serve immediately.
