The Unlikely Superbean: Why I Rediscovered the Lupini

Years ago, I don’t even remember where—maybe in Italy—I remember eating these fun, salty, yellow beans. You’d bite into the side of the skin and pop out the inner bean. I didn’t know what they were or how to find them, but they were clearly a popular snack, similar to how fava beans are enjoyed in Israel, where people sit around snacking on the beans while hanging out with friends.

The first time I had them, they weren’t plain. They were dressed simply with a bit of olive oil and a hint of rosemary. When I eventually found them in a jar at a specialty store, I realized they were typically eaten straight from the salty brine. But I never forgot that first, subtly dressed experience—a simple drizzle of oil and rosemary is such a nice way to elevate a ready-made snack.

For years, I completely forgot about them. Just like so many things, I go through phases of obsession. But then, recently, I saw them trending everywhere! Food bloggers and health sites were hailing them as the “next great superbean” because of their incredible nutritional profile: sky-high protein and fiber, yet super low in carbohydrates.

I was instantly back in that cafe, wondering: Why did I ever stop eating these?

I immediately went and picked up a jar. I’ve since read that you can find them already peeled in some places, and that people are grinding them into flour for baking. While that sounds amazing, I’m too lazy to peel them myself, so for now, I’m sticking to the jarred version. And honestly, for a snack this healthy and satisfying, I highly recommend them as a new favorite addition to your pantry.

What Makes Lupini a “Superbean”?

If you’re looking for a plant-based food that truly ticks all the boxes, the lupini bean (also called lupin bean) is it. Considered one of the most nutritionally dense legumes on the planet, it’s an ideal choice whether you’re following a low-carb, keto, vegan, or simply a health-focused diet.

Why it’s so good for you:

High in Protein (about 16g per 100g cooked): Lupini beans pack more protein than many common legumes like chickpeas or soybeans. That makes them an excellent source of plant-based muscle fuel, helping you feel satisfied and energized.
Rich in Fiber (roughly 3–10g per 100g cooked): Fiber is essential for gut health, digestion, and lasting fullness — all key for overall wellness and weight management.
Low in Net Carbs (around 7g per 100g cooked): Lupini beans are very low in starch, making them a go-to for anyone managing blood sugar or following low-carb and ketogenic lifestyles.
Loaded with Vitamins & Minerals: They provide important nutrients like manganese, magnesium, iron, and B vitamins — supporting everything from bone health to energy metabolism.
