Sure thing! To make these White Cheddar Stuffed Mushrooms gluten-free you just need to make adjustments. Instead of using Panko breadcrumbs go for a gluten-free version. Nowadays there are alternatives there that have the same texture and taste, as regular Panko. As for the white cheddar sauce if you usually thicken it with flour try using a gluten-free flour blend or cornstarch. These substitutes work well in keeping the sauce creamy without any gluten. Don't forget to check the labels of ingredients, like Worcestershire sauce and cheeses to ensure they're truly gluten-free.
