What Is a Peanut Actually More Closely Related To?

If you guessed B. Lentils, you got it! 🎉

Peanuts might have “nut” right in the name, but botanically, they’re not actually nuts.

Peanuts are legumes, which means they’re more closely related to lentils, beans, and peas than to almonds, pecans, or walnuts.

And that’s not the only surprising thing about them. Unlike tree nuts, peanuts actually develop underground.


So, What Makes a Peanut a Legume?

Peanuts belong to the legume family, the same plant family that includes lentils, beans, peas, and chickpeas.

Legumes typically produce seeds inside pods. Crack open a peanut shell and you’ll find the edible seeds inside, which is one clue to where peanuts really belong in the plant world.

So even though we usually eat, cook with, and shop for peanuts alongside nuts, botanically they’re part of a different family.


How Do Peanuts Grow?

This is where peanuts get even more interesting.

Peanut plants produce small flowers above ground. After a flower is pollinated, a stem called a peg begins growing downward and pushes into the soil.

The peanut pod then develops underground.

Peanut Plant → Flower → Peg Grows Downward → Pod Develops Underground → Peanuts Harvested


Peanuts vs. Tree Nuts

They may share a spot in the snack aisle, but they grow very differently.

Peanuts are legumes that develop in pods underground.

Tree nuts, such as almonds, walnuts, and pecans, grow on trees.

That’s why the word “nut” in peanut can be a little misleading. In the kitchen, we may treat peanuts like nuts, but botanically, they belong with legumes.


What Do Peanuts Taste Like?

Peanuts have a familiar rich, nutty flavor that can change depending on how they’re prepared.

Raw peanuts have a milder flavor, while roasting brings out a deeper, more toasted taste and crunch.

Try them in:

  • Trail mix
  • Homemade granola
  • Salads
  • Stir-fries
  • Baked goods
  • Peanut sauces
  • Snacks on their own


A Nut in Name, a Legume by Nature

So the next time you reach for a handful of peanuts, remember their somewhat surprising relatives:

lentils, beans, peas, and other legumes.

It’s another everyday pantry staple with a story that’s a little less obvious than its name suggests.
