Peanuts coated in a spicy chile-lime seasoning are a bold Mexican snack. This high protein, family-friendly treat is a fresh, keto-friendly option packed with crunch and heat.
Preheat the oven to 325°F for even roasting and line a baking sheet with parchment paper.
In a large bowl, whisk the egg white until frothy but not stiff; this helps the seasoning cling to the peanuts.
Toss the raw peanuts in the egg white, ensuring each peanut is lightly coated.
In a small bowl, combine chile powder, lime juice, salt, and cayenne pepper, then sprinkle over the peanuts and toss to coat thoroughly.
Spread the seasoned peanuts evenly in a single layer on the prepared baking sheet and bake for 18–22 minutes, stirring once halfway for even roasting.
Allow the peanuts to cool completely on the pan; they will crisp as they cool. Store in an airtight container once cooled.
