Drain and dry the beans

• Drain and rinse the canned kidney beans in a colander.
• Pat them dry really well with a clean towel; the drier they are, the crispier they get.

Season the beans

• Spread the beans on a baking sheet in a single layer.
• Spray them with oil and sprinkle with the Cajun seasoning and salt.
• Toss to coat evenly.

Bake until crunchy

• Bake at 175 °C (350 °F) for 30 to 40 minutes, stirring halfway through, until crunchy.
• Alternatively, cook them in an air fryer.

Serve

• Snack on them straight, sprinkle over salads, or use anywhere you want crunch.
