My grandfather brought these to every family gathering without fail. Just 3 ingredients for a savory, melt-in-your-mouth snack that vanishes fast.

For a slightly different flavor, you can swap the Swiss cheese for shredded cheddar, Colby-Jack, or a mix of Swiss and mozzarella, keeping the same total amount so the bites still hold together and crisp nicely. If you like a stronger, deli-style taste, stir in a teaspoon or two of prepared horseradish or spicy brown mustard (this technically adds an extra ingredient, but it’s a small flavor boost that my grandfather would sneak in now and then). To stretch the recipe for a crowd while staying low carb, fold in a small handful of very finely chopped green onion or minced sauerkraut—just blot them dry first so the mixture doesn’t get watery. You can also make these ahead: mix and portion the mounds on a lined baking sheet, cover, and refrigerate for up to a day, then bake right before guests arrive. For crisper bites, use slightly smaller mounds and bake a minute or two longer, watching closely so the cheese turns golden brown without burning.
