These oven baked fontina sage potato crisps are the kind of simple little appetizer that feels a bit special without asking much from you. My aunt has made versions of these for years for casual gatherings, and it makes sense why they vanish so fast: thin potato slices turn crisp at the edges, fontina melts into a rich savory topping, and sage brings that cozy earthy flavor that makes the whole tray feel holiday-worthy even on an ordinary weeknight.
Serve these warm as a party bite on their own, or pair them with a simple green salad, roasted chicken, tomato soup, or a small cheese board for a relaxed appetizer spread. They also work nicely alongside sparkling water, crisp white wine, or apple cider if you want something refreshing to balance the buttery cheese and potatoes.
Oven Baked 4-Ingredient Fontina Sage Potato Crisps
Servings: 6
Ingredients
2 medium Yukon Gold potatoes, sliced into very thin rounds
1 1/2 cups shredded fontina cheese
12 fresh sage leaves
2 tablespoons olive oil
Directions
1. Preheat the oven to 425°F and line a large baking sheet with parchment paper. Slice the potatoes into very thin, even rounds, then pat them dry with paper towels so they crisp well in the oven.
2. Arrange the potato slices in a single layer on the prepared baking sheet. Brush both sides lightly with olive oil, then bake for 15 minutes.
3. Remove the pan from the oven, flip the potato rounds, and return them to the oven for 10 to 12 minutes more, until the edges are golden and the centers are nearly crisp.
4. Top each potato round with a small pinch of shredded fontina and one sage leaf. Bake for 3 to 5 minutes more, just until the cheese is melted and bubbling and the sage looks crisp.
5. Let the crisps cool for 2 to 3 minutes so they firm up a bit, then transfer to a serving board or platter and serve warm.
Variations & Tips
Add a little salt and pepper: If your four-ingredient version feels too bare, a light sprinkle of kosher salt and black pepper right before baking brings out the potato and cheese flavors beautifully.
Use a mandoline for even slices: The biggest trick to getting crisp results is slicing the potatoes as evenly as possible. When I'm making these after work and don't want surprises, a mandoline makes the process much faster and gives more reliable browning.
Try a different cheese: Gruyère or provolone can work if fontina is hard to find. The flavor will shift a bit, but both melt nicely and still pair well with sage.
Keep them crisp for serving: For the best texture, serve these within about 10 minutes of baking. If you're making them for guests, you can bake the potato slices ahead, then add the cheese and sage for the final few minutes right before serving.
