Snack on Homemade Crunchy Roasted Beans UncategorizedBean Bulletin, Cooking Roasted beans make a crunchy, healthy inexpensive snack or topping for salad. And they’re easy to make at home. Large, firm types like pinto or kidney beans work best. Drain and rinse a 15-ounce can of beans. Toss them in a bowl with one tablespoon of olive oil and ½ to ¾ teaspoons of favorite spices like chili powder and garlic powder plus a sprinkle of salt. Transfer the beans to a parchment-lined baking sheet and bake at 400 degrees until they are dry and crisp, about 30 minutes.
