Our stovetop-to-oven method means you can skip the butter and still get a crispy, gooey grilled cheese.
Preheat oven to 375 degrees. Divide cheddar among 4 slices bread. Spread jelly on 4 more slices bread and sandwich together. Coat a large skillet with cooking spray and heat over medium. Working in batches, if necessary, cook until bread is golden and toasted, 2 minutes, flipping once. Transfer to a baking sheet and bake until cheese is melted, 3 to 5 minutes. To serve, cut into sticks or triangles.
