Boiled Peanuts Nutrition Facts: Calories, Carbs, and Protein
A cup of shelled boiled peanuts runs about 200 calories, 8 grams of protein, 13 grams of carbs, and 5 grams of fiber. Sodium depends entirely on how salty your brine is. Boiling adds water, so they're less calorie-dense than roasted. Here are the real numbers.
I've handed out a lot of paper cups of boiled peanuts over the years, and sooner or later somebody standing over the pot asks, "So how bad are these for me?" Fair question. The honest answer is they're one of the better snacks you can hold in your hand, and I'll give you the numbers to prove it. This page is the facts table. If you want the bigger conversation about whether they're actually good for you, I break that down separately in are boiled peanuts healthy.
Boiled peanuts nutrition per cup
Here's roughly what one cup of shelled boiled peanuts (about 63 grams of edible peanut, no shells) delivers. Real food varies, so treat these as close-enough, not lab-exact.
- Calories: ~200
- Protein: ~8 g
- Total carbohydrate: ~13 g
- Dietary fiber: ~5 g
- Total fat: ~14 g (mostly the good unsaturated kind)
- Sodium: ~300–800 mg (this one's up to you — more on that below)
Per 100 grams, if you like it clean
Nutrition labels usually run per 100 grams, so here's that version. Boiled peanuts soak up water in the pot, which is why the same weight has fewer calories than dry roasted peanuts.
- Calories: ~315
- Protein: ~13 g
- Carbohydrate: ~21 g
- Fiber: ~8 g
- Fat: ~22 g
Compare that to roasted peanuts at roughly 567 calories per 100 grams and you can see what the water does. Boiling doesn't magically remove fat — the peanut just carries more moisture, so you get more snack per calorie. I dig into that head-to-head in boiled vs roasted peanuts if you're curious which way to go.
The carbs deserve a second look
Thirteen grams of carbs a cup sounds ordinary until you notice that about five of them are fiber. That's a solid chunk. Fiber is the part your body doesn't cash in as quick sugar, so the "net" carbs land closer to 8 grams. Green peanuts boiled slow also pick up some resistant starch, which behaves a lot like fiber. For a shelled, salted snack you eat by the handful, that's a friendly macro profile — protein and fiber doing most of the talking.
Protein: about 8 grams and honest about it
Eight grams of plant protein per cup isn't going to replace a steak, but it's real, and it comes packaged with fiber and healthy fat instead of a bunch of empty filler. Sit on a cooler with a cup of hot peanuts and you'll notice they actually hold you over. That's the protein and fat working together. It's the same reason my grandpa could shell peanuts all afternoon and skip lunch.
Sodium is the number you control
Here's the one people worry about, and rightly so. Boiled peanuts are salted, so sodium is the wild card — anywhere from a few hundred milligrams to well over a thousand per cup, depending on how heavy the brine is and how long they soaked. The peanut is basically a little sponge sitting in salt water.
The good news: you're the one holding the salt box. My real recipe uses coarse kosher salt — about a cup per half-bushel pot — which lands you in a reasonable range, not a blood-pressure ambush. If you're watching sodium, boil them a touch lighter on the salt and let them rest in the brine for less time. You lose nothing but a little saltiness. This is exactly why I don't drown mine in Old Bay and Cajun seasoning by default — that stuff piles sodium on top of sodium. If you want the spicy version done right, I cover it honestly in cajun boiled peanuts, but plain salt is the purist's move and the easiest to keep in check.
Why boiling changes the numbers at all
People make boiled peanuts harder than they have to be, and they overthink the nutrition too. The short version: a raw green peanut is one thing, a roasted peanut is a dried-out, calorie-dense thing, and a boiled peanut is a hydrated, softer, lower-density thing. Same peanut, three states. Boiling with time and salt is what gets you that tender bite and the friendlier calorie count. If you've never watched it happen, my full how to make boiled peanuts walkthrough shows the whole slow-pot process — peanuts, salt, water, time, nothing else.
How to eat them without overdoing it
A cup is a genuine snack. Two cups and you're into small-meal territory, which is fine — just know the sodium is riding along with you. Eat the peanut, sip the potlikker if you love it (I do), and don't eat the shells. If you're new to the ritual, how to eat boiled peanuts covers the whole hands-on business.
Bottom line on the numbers
Boiled peanuts are about 200 calories, 8 grams of protein, 13 grams of carbs with 5 grams of fiber, and however much sodium you decide to add. For a snack you can sit and shell for an hour, that's about as honest as food gets. Nothing on that list is a gimmick — it's a green peanut and some salt water doing exactly what they've done down here for two hundred years.
