Ingredient Notes & Details

Ground beef
Use 80/20 for the juiciest patties. Leaner beef can dry out.

Rye bread
Classic choice with a subtle tang. Sourdough or Texas toast also work well.

Swiss cheese
Traditional and perfectly melty. Provolone or American can be substituted.

Yellow onions
These caramelize beautifully and become sweet and tender.

Butter
Essential for golden, crispy bread and rich flavor.

Salt and black pepper
Simple seasoning lets the beef shine.

Optional garlic powder
Adds a gentle savory depth without overpowering.
