- Mustard
- Pickle relish
- Garlic powder

Set aside.
Step 4: Cook the Burgers
Heat a cast-iron skillet or grill over medium-high heat.
Cook the patties for 3–4 minutes per side.
During the last minute of cooking, place a slice of cheddar cheese on each patty and let it melt.
Step 5: Toast the Buns
Spread butter on the cut sides of the burger buns.
Toast them in a skillet for 1–2 minutes until golden.
Step 6: Assemble the Burgers
Spread burger sauce on the bottom bun.
Layer with:
