Recipe Questions & Answers

→ What’s the trick to great caramelized onions?

Cook them nice and slow on low heat, stirring every so often. It should take about 15-20 minutes. Add a splash of water if they get sticky.

→ Can I make the sauce early?

Absolutely! Prep the sauce up to 3 days in advance and keep it in the refrigerator. The flavors get better as they sit.

→ Why mix two cheeses together?

Swiss melts beautifully and is nutty, while cheddar gives a tangy kick and color. Combined, they taste amazing and melt perfectly.

→ How thin do I make the patties?

Keep them thinner than regular burgers, about 1/4 inch. Make them a tad bigger than the bread so they fit perfectly after cooking.

→ How can I stop the bread from burning?

Cook on medium heat and stay nearby. Let the cheese start melting before flipping. 2-3 minutes per side usually works.
