Frequently Asked Questions

How long should I cook the burger on each side?

For optimal results, aim to cook the burger for about 2-3 minutes on each side until the internal temperature reaches 165F. However, the exact timing may vary depending on the thickness of your burger patties.

Can I prepare the patties in advance and store them for later use?

Absolutely! You can prepare the patties in advance and freeze them for later use. Once formed, simply store them in the freezer until you're ready to cook them.

Can I grill the burgers instead of cooking them on a pan?

Grilling the burgers is possible, but it's important to use a cast iron grill pan to achieve the best results. This type of pan allows you to properly smash down the burger while it cooks, ensuring you get the proper smash burger texture.

Storage Tips

For optimal freshness, it’s best to consume the leftovers promptly, ideally right after preparation. However, if leftovers are inevitable, store them in an airtight container and refrigerate promptly where it will keep for 1-2 days.
