Frequently asked questions
+ − Can I make the patties ahead of time?
Absolutely! The patties actually taste better when made ahead. You can form them up to 24 hours in advance and keep them refrigerated, or freeze them for up to 3 months. The resting time allows the seasonings to penetrate the meat for better flavor.
+ − What's the best way to get perfectly caramelized onions?
Low and slow is the key. Cook them over medium to medium-low heat for about 15 minutes, stirring occasionally. Don t rush the process properly caramelized onions should be golden brown and sweet, not burnt or crispy.
+ − Can I use a different type of cheese?
Yes! While cheddar is classic, Swiss, American, provolone, or even pepper jack work wonderfully. Choose a cheese that melts well and complements the other flavors.
+ − How do I know when the patties are done?
Cook for 3 minutes per side for medium doneness, or until the internal temperature reaches 160°F (71°C) for food safety. The patties should feel firm to the touch and the juices should run clear.

Ingredients
Instructions
- 1
In a medium bowl, gently mix ground sirloin, Worcestershire sauce, minced garlic, salt, and pepper using your hands. Don't overmix to keep the patties tender. Form the mixture into 4 evenly-sized hamburger patties, wrap each in plastic wrap, and refrigerate for at least 4 hours or overnight to let the flavors meld.
- 2
Heat butter and olive oil in a large skillet over medium heat until the butter melts and starts to foam. Add sliced onions and sauté, stirring occasionally, until they turn golden brown and caramelize, about 15 minutes. If the onions start sizzling too aggressively, reduce heat to medium-low to prevent burning.
- 3
Spray a large skillet with cooking spray and heat over medium heat. Remove patties from refrigerator and cook for 3 minutes on the first side. Flip the patties and immediately top each with a slice of cheddar cheese. Cook for another 3 minutes until the cheese melts and the patties are cooked through.
- 4
Place each cooked patty on a slice of toasted rye bread. Top generously with the warm caramelized onions, add a spread of Dijon mustard if desired, and crown with the remaining bread slices. Serve immediately while the cheese is still melted and the bread is crispy.
