Rinse your fresh Kale leaves to get rid of all impurities. Tap the leaves dry so that no water is left.
Preheat your oven to 350 Fahrenheit/ 180 Celsius.
Cut off the tough stem parts and discard the stem.
Cut the kale leaves into smaller sizes. I like to cut them into bite-sized pieces. The size is up to you.
Grab a large bowl and add the olive oil, balsamic vinegar, salt, and black pepper to the bowl. Mix together to create the seasoning for the kale chips.
Add the kale leave pieces to the large bowl and mix. The leaves should be completely covered by the seasoning.
Keep a baking tray ready with a baking sheet and place the marinated kale leaves on the baking sheet. Spread them out and work in batches. Don't overcrowd the baking sheet.
Oven bake the kale leaves at 350 Fahrenheit/ 180 Celsius for about 10-14 minutes. (I keep mine at 12 minutes). Check if they are crisp enough. The time might vary between ovens.
Allow your balsamic kale chips to cool. Store in an airtight container in the fridge or consume instantly.
