Wash and dry sage leaves. Cover a large plate with a couple layers of paper towels; set aside.
Cover the bottom of your frying pan with about ¼ inch of olive oil (I used 3 tablespoons for a 10-inch pan). Warm oil over medium heat until hot.
When oil is hot, add sage leaves in a single layer, carefully swirling pan to make sure leaves are covered with oil.
Fry sage leaves just until they turn dark green, about 30 seconds to 1 minute (no need to flip). Immediately remove from oil using tongs. Place leaves on paper towel-covered plate. (Do not brown leaves.)
Sprinkle sage with kosher salt, then serve. Enjoy!
Notes
Cleaning the Sage - Before starting, rinse your sage with water and pat it dry. Make sure it's completely dry before frying, because any water clinging to the leaves will cause the hot oil to splatter. Scaling the Recipe -You can cook as many (or as few) leaves as you would like. If you're planning to fry lots of leaves, I'd recommend doing it in batches. They cook really quickly, and if you cook too many at once, the leaves may burn before you can remove them from the pan. Add more oil and use a larger frying pan, if necessary. The oil should completely cover the bottom of the pan.Save the Oil - Don't throw out the sage-flavored oil when you'd done! You can drizzle it over veggies or soup, use it in vinaigrettes and sauces, and more.Calories - It's difficult to determine the exact amount of calories for this recipe, but I based my calculations on frying 20 leaves in 3 tablespoons of oil. After cooking, 2 ½ tablespoons of oil remained in the pan. One serving of 4 leaves has about 14 calories (5 servings total), probably even less because the paper towels absorbed some of that oil.More Tips - Check out the info before this recipe card for helpful tips, step by step photos, serving suggestions, and more!
