Stout Burger FAQs
The questions that come up most: how to cook the patty, what the stout adds, which mushrooms work best, and how to swap the cheese.
How do you cook the patty?
Season the formed patties just before cooking and sear over high heat for a browned crust, flipping once. Cook ground beef to a safe internal 160°F, per the USDA.
What does the stout add?
A spoon of Guinness in the mayo brings a malty, slightly bitter depth that balances the rich Gruyère and the sweetness of the fried onions.
What mushrooms work best?
Cremini or button mushrooms, sliced and sautéed until golden so their moisture cooks off and their flavor concentrates.
Can you use a different cheese?
Gruyère melts smooth and nutty, but Swiss or a good Emmental give a similar melt if you cannot find it.
