Preheat your oven to 350°F (175°C) to create the ideal roasting environment for your Paprika and chili kale chips.

Prepare two baking trays by completely lining them with parchment baking papers so the leaves don't stick or tear.

Trim the tough center stems from the 1 bunch (8.0 oz / 225g) of curly kale and carefully chop the remaining leaves into small, uniform, bite-sized pieces.

In a large mixing bowl, vigorously whisk together the 2 tbsp. (1.0 oz / 30g) extra virgin olive oil, 1 tsp. (0.1 oz / 3g) paprika, and 0.5 tsp. (0.05 oz / 1.5g) dried red chili flakes until perfectly combined.

Add the chopped greens into the bowl and gently massage the leaves with your hands, tossing them until every single piece is well coated with the spicy oil blend.

Spread the coated kale out in a single, even layer on the prepared baking dishes, making sure the pieces do not overlap (use two trays to prevent steaming).

Bake in the preheated oven for exactly 12 minutes, or up to 15 minutes, watching them very closely so they become beautifully crisp but do not burn.

Remove the trays from the oven and immediately sprinkle the hot chips evenly with 0.1 tsp. (0.05 oz / 1.5g) sea salt before serving.

While I am an AI and don't get to enjoy the satisfying crunch of these chips firsthand, the culinary data on roasting leafy greens is crystal clear. To guarantee absolute perfection, keep these professional rules in mind:

Bone-Dry Leaves are Mandatory: Any residual water on your kale will create steam in the oven, leading to soggy, wilted greens instead of a crisp chip. Use a salad spinner and then thoroughly pat the leaves dry with paper towels.

Don't Skip the Massage: Gently rubbing the olive oil and spice mixture into the leaves isn't just for show. It breaks down the tough cellulose structure of the curly kale and ensures the spices stick evenly to every crevice.

Give Them Space: Overcrowding your baking sheet is the enemy of crispiness.

Make sure the kale is in a single layer with a little breathing room. If you have to use a third baking sheet, do it!

Salt After Baking: Salt draws out moisture. If you salt the kale before it goes into the oven, it can pull water to the surface and hinder the crisping process.

Sprinkle your sea salt immediately after pulling them from the oven while the oil is still hot.
