Ingredients Needed
- 225g / 1 ½ cups Lupini beans (canned, jarred, or vacuum-sealed)
- 1 tbsp Lime juice
- 1 tbsp Olive oil
- 1 tsp Chili powder
- ¼ tsp Sea salt (or to taste)
- ¼ tsp Black pepper (or to taste)
How To Make Low Carb Keto Lupini Beans
- Drain and dry the lupini beans: Drain in a colander, rinse well, then pat dry with a paper towel.
- Mix the seasoning: In a medium bowl, whisk together the lime juice, olive oil, chili powder, sea salt, and black pepper. Add the lupini beans and toss to coat evenly.
- To cook in the air fryer: Arrange the coated beans in a single layer at the bottom of the air fryer basket. Air fry at 380°F / 193°C for 10 minutes, stirring halfway through.
- To cook in the oven: Spread the beans in a single layer on a baking sheet. Bake at 400°F / 204°C for 15 minutes, stirring halfway through.

Recipe Tips
- Pat the beans dry: After rinsing, make sure to dry the lupini beans well with a paper towel. This helps them crisp up better in the air fryer or oven.
- Coat evenly: Toss the beans thoroughly in the seasoning mix to ensure every bite is full of flavor.
- Use a single layer: Spread the beans out in one layer in the air fryer or on the baking sheet. Overcrowding will make them less crispy.
- Adjust seasoning to taste: Lupini beans can be slightly bitter, so feel free to add extra lime juice or chili powder for more flavor.
- Let them cool for extra crunch: The beans will crisp up even more as they cool, so let them sit for a few minutes before eating.
How To Store and Reheat Leftovers?
- Refrigerate: Let the leftover lupini beans cool to room temperature. Store them in an airtight container in the fridge for up to 5 days.
- Reheat: Spread the lupini beans on a baking sheet and bake at 180°C / 350°F for 5-7 minutes until warm and crispy again.
