What Kind of Beans Are Lima Beans?
Lima beans are legumes classified as a type of common bean (Phaseolus lunatus), characterized by their distinctive kidney shape and starchy texture.
Introduction to Lima Beans: Beyond the Butter Bean
Lima beans, often unfairly relegated to the realm of childhood culinary aversions, are far more complex and fascinating than their bland reputation suggests. Belonging to the Phaseolus genus, the same family as kidney beans, black beans, and pinto beans, they represent a globally cultivated crop with a rich history and diverse culinary applications. Understanding their botanical classification, nutritional profile, and preparation methods can unlock a newfound appreciation for these versatile legumes. Often called butter beans, especially when referring to smaller, creamier varieties, lima beans offer a substantial nutritional punch and adaptable flavor.
Botanical Classification and Origins
Lima beans are a species of legume, Phaseolus lunatus, belonging to the Fabaceae family, a broad group encompassing peas, lentils, soybeans, and other bean varieties. Two primary genetic lineages exist: one originating in the Andes Mountains of South America and the other in Mesoamerica. These distinct lineages have led to the development of a wide array of lima bean varieties, differing in size, color, and flavor. From the tiny, delicate baby limas to the larger, more robust Fordhook varieties, the genetic diversity of the lima bean is remarkable.
Nutritional Powerhouse
Beyond their culinary versatility, lima beans boast an impressive nutritional profile. They are an excellent source of:
- Protein: Essential for muscle building and repair.
- Fiber: Promoting digestive health and satiety.
- Iron: Crucial for oxygen transport and energy production.
- Potassium: Important for maintaining healthy blood pressure.
- Folate: Vital for cell growth and development, particularly during pregnancy.
- Manganese: An antioxidant that supports bone health.

From Field to Table: Choosing and Preparing Lima Beans
Selecting the right lima beans and preparing them properly is key to unlocking their full potential.
Fresh vs. Dried vs. Frozen: Fresh lima beans are available seasonally and offer the most delicate flavor. Dried lima beans require soaking and longer cooking times but are shelf-stable. Frozen lima beans are a convenient option, retaining much of their nutritional value.
Soaking (for dried beans): Soaking dried lima beans overnight, or using the quick-soak method (boiling for 2 minutes, then resting for 1 hour), helps reduce cooking time and improve digestibility.
Cooking: Lima beans should be cooked until tender but not mushy. Simmering them gently in water or broth is ideal. Avoid overcooking, as this can result in a less desirable texture. Adding a small amount of salt towards the end of cooking can enhance the flavor.
Removing Bitterness: Some varieties of lima beans contain higher levels of compounds that can cause a slightly bitter taste. Soaking and changing the cooking water once or twice can help mitigate this.
Lima Beans in Global Cuisine
Lima beans feature prominently in various culinary traditions around the world. In the Southern United States, they are a staple ingredient in succotash, a comforting dish of corn and lima beans. In Latin America, they are used in soups, stews, and side dishes. They’re also popular in Mediterranean cuisine. Butter beans are often enjoyed simply boiled and served with butter, salt, and pepper, highlighting their creamy texture.
Common Misconceptions and Culinary Redemption
Many people harbor negative associations with lima beans, often stemming from childhood experiences with overcooked or poorly prepared versions. However, when cooked properly, lima beans can be a delightful addition to any meal. Experimenting with different varieties, cooking methods, and flavor pairings can help overcome these misconceptions and unlock the true potential of this often-underestimated legume.
Frequently Asked Questions (FAQs) about Lima Beans
What is the difference between baby lima beans and regular lima beans?
Baby lima beans are simply smaller varieties of Phaseolus lunatus. They tend to have a more delicate flavor and creamier texture compared to the larger, more mature lima beans.
Are lima beans the same as butter beans?
While the terms are often used interchangeably, butter beans generally refer to smaller, creamier varieties of lima beans. In some regions, the term “butter bean” is exclusively used for these smaller types. All butter beans are lima beans, but not all lima beans are butter beans.

How can I tell if my lima beans are cooked enough?
Cooked lima beans should be tender but not mushy. You should be able to easily pierce them with a fork. Overcooked lima beans will become soft and lose their shape.
How do I get rid of the bitter taste in lima beans?
Soaking the dried lima beans overnight before cooking, or using the quick-soak method, can help reduce bitterness. Changing the cooking water once or twice during simmering can also help.
Can I freeze lima beans?
Yes, cooked lima beans freeze well. Allow them to cool completely before transferring them to freezer-safe containers or bags. They can be stored in the freezer for several months.
