Frequently Asked Questions
- → What mushrooms work best for this burger?
- Cremini and Baby Bella mushrooms are great options since they’re meaty and full of flavor. If you prefer a lighter taste, white button mushrooms work well too, or mix different types for a more complex profile.
- → How do you stop burger patties from shrinking?
- Shape the patties a little wider than your buns and gently press your thumb into the center to make a shallow dimple. This keeps them flat as they cook. Also, avoid overhandling the meat since it can turn tough.
- → Can the mushroom topping be made ahead?
- Definitely! Cook the mushrooms a day or two in advance and store them in the fridge. When you’re ready, just warm them up in a pan before serving to save time.
- → What’s the best way to melt Swiss cheese?
- Place the cheese on the patties during the last minute of cooking and cover the pan with a lid. The steam will gently melt the cheese over the meat without overcooking it.
- → What sides go best with Mushroom Swiss Burgers?
- You can’t go wrong with crispy fries, onion rings, or even a fresh salad. Add a tangy pickle for extra contrast, or try sweet potato fries for something different.
