Frequently Asked Questions
- → Which mushrooms work best for these burgers?
- Baby Bella and cremini mushrooms are fantastic for this recipe because they’re hearty and full of flavor. You could also use white button mushrooms for a milder taste, or mix different mushrooms for a more layered flavor.
- → What’s the trick to stop burger patties from shrinking?
- Make sure the patties are larger than your buns and lightly press a dent in the center with your thumb before cooking. This keeps them flat while they cook. Also, don’t overmix the meat—it can make the burgers tough.
- → Can I prepare the mushroom topping in advance?
- Absolutely! You can cook the mushrooms up to two days ahead and keep them refrigerated. Reheat them on the stove before adding them to your burger for quick prep on busy days or when hosting.
- → How can I melt the Swiss cheese perfectly?
- To get the cheese melted just right, place the slices on the patties near the end of cooking and cover the pan with a lid or bowl. The steam will melt the cheese evenly without overcooking the meat.
- → What are the best sides for Mushroom Swiss Burgers?
- Crispy fries (regular or sweet potato), onion rings, or even a fresh side salad complement these burgers well. If you’re craving something tangy, add a pickle on the side for balance.
