How Many Calories Are In Purple Hull Peas? | Smart Scoop

Calories In Purple Hull Peas Per Cup (Cooked)

When you cook shelled peas from the purple-hulled cowpea family, one level cup typically lands around 190–220 calories. That bracket reflects the well-documented numbers for cooked black-eyed peas and other southern cowpeas, which share the same species and nutrient profile. A widely used nutrient database that compiles USDA FoodData Central–sourced values lists ~198 calories for a 1-cup cooked portion (about 171 g) of mature seeds, with ~13 g protein and ~11 g fiber. Real-world packs labeled “purple hull” sometimes show a bit more per ½ cup because of brine or seasonings; draining and rinsing usually narrows the gap.

Why The Numbers Vary

Three levers nudge the math: (1) maturity at harvest (immature “green” peas run a little lighter), (2) cooking medium (salt, fat, and aromatics add calories), and (3) water uptake (firmer peas hold less water and weigh less per cup). That’s why labels on frozen or canned options can range from about 90–120 calories per ½ cup, while home-cooked dry peas hew close to the 190–200-calorie cup baseline.

Form	Typical Serving	Estimated Calories
Cooked From Dry (unsalted)	1 cup (≈171 g)	≈198 kcal

Canned, Drained/Rinsed	½ cup (≈130 g)	≈90–120 kcal

What Counts As “Purple Hull” In Nutrition Terms?

Nutrition references classify these peas as cowpeas or southern peas, which include black-eyed, crowder, cream, and pink-eyed types. Extension bulletins confirm that purple-hull types sit inside this group, so their cooked nutrition mirrors black-eyed peas and other cowpeas. See Oklahoma State’s fact sheet noting names such as “blackeyes,” “crowders,” and “pinkeye-purple hulls” within southern peas, all under the cowpea umbrella. OSU Extension: southern peas naming

Macros, Fiber, And Satiety

Per cooked cup, expect roughly 13 g protein, 35 g total carbs, 11 g fiber, and under 1 g fat when you prepare them plain. That profile makes these peas filling without being heavy. The fiber count fits neatly alongside official dietary advice; if you’re tracking fiber targets, skimming a concise list from the Dietary Guidelines helps put the cup-by-cup numbers in context.

Portion Tips For Everyday Meals

• As a side: ½ cup cooked (≈90–110 kcal) sits well with grilled fish or roasted chicken plus greens.
• In soups and stews: ¾–1 cup cooked (≈150–200 kcal) adds body and protein, so scale starches elsewhere.
• In bowls and salads: ½–1 cup cooked pairs with tomatoes, onion, and a light vinaigrette.

Cooking Method And Calorie Impact

Dry Beans: Best Control

Simmering from dry gives you full control over sodium and added fat. A standard quick-soak or overnight soak shortens cooking time, and simmering in plain water keeps the per-cup count close to ~198 kcal for mature seeds drawn from black-eyed/cowpea data.

Frozen Shelled: Speed With Consistency

Frozen shelled peas deliver predictable texture in 20–40 minutes on the stove. Some packs are blanched with a touch of sodium; light seasoning at home doesn’t move the calorie count much unless oil or meat is added. If the label lists 90–120 calories per ½ cup, a full cup typically doubles that.

Canned: Fastest, With A Sodium Caveat

Canned options are ready in minutes. Draining and rinsing trims sodium by roughly one-third while leaving calories essentially unchanged. Flavor boosters like bacon drippings or butter do change the math—one tablespoon of oil adds about 120 calories to the whole pot, which can raise each ½-cup serving by 15–30 calories depending on batch size.

Strengths Beyond Calories

These peas bring folate, iron, potassium, and a dependable fiber hit. That’s why nutrition databases highlight them among budget-friendly sources of plant protein and fiber. A cup of cooked mature seeds from the same cowpea group generally offers double-digit grams of fiber and a similar protein tally. For the baseline macro snapshot tied to cooked mature seeds, see the black-eyed/cowpea entry built from FoodData Central.

Hitting fiber targets gets easier when meals include legumes like these and produce on the side; if you want a quick benchmark, the recommended fiber intake page lays out daily ranges in plain numbers.

Cup-By-Cup Breakdown (Nutrition Snapshot)

Use this mid-article table to plan sides and mains without guessing. Values refer to plain, cooked mature seeds from the cowpea family.

Measure	Approx. Macros	Notes
½ cup cooked	~95–110 kcal | ~6–7 g protein | ~5–6 g fiber	Great as a side or salad add-in.
1 cup cooked	~190–220 kcal | ~12–14 g protein | ~10–12 g fiber	Solid main-dish portion with greens.
1½ cups cooked	~285–330 kcal | ~18–21 g protein | ~15–18 g fiber	Build a bowl; adjust fats to taste.

Label Literacy: What To Look For

Serving Size

Frozen packs often list ½ cup (≈81 g). Canned legumes commonly use ½ cup (≈130 g) as drained weight. Dry-cooked at home is easiest to map to the 1-cup, ~171 g standard used by nutrition databases.

Added Fats And Flavorings

Seasoning blends add negligible calories, but fats and meat do not. If a pot of peas gets two tablespoons of oil, tack on ~240 calories to the total; spread across six ½-cup servings, that’s ~40 extra per serving.

Sodium

Sodium doesn’t add calories, but it affects water retention and taste. Rinse canned peas and season at the end. If you cook from dry, salt toward the finish for creamy interiors without tough skins.

How These Peas Fit The Cowpea Family

Horticulture references group purple-hull types within southern peas under the species Vigna unguiculata. That’s the same family you see labeled as black-eyed, crowder, or cream peas, so matching them to black-eyed/cowpea nutrition is appropriate for calorie planning. Land-grant extensions document the naming and varieties, including pink-eyed purple hull lines grown across the South. Helpful context: southern peas naming and a short note on how purple pods signal harvest from Mississippi State’s horticulture pages (MSU Extension).

Simple, Calorie-Aware Ways To Cook

Lean Pot Method

Simmer with onion, garlic, bay leaf, and pepper. Finish with lemon juice and a splash of hot sauce. Calories stay near the baseline since you haven’t added fat.

Smoky But Light

Use a small piece of smoked turkey wing instead of bacon. You get savory depth with fewer added calories than a fatty cut. Skim any visible fat after cooking and measure your portion before adding rice or cornbread.

Salad Route

Chill cooked peas and toss with chopped tomatoes, bell pepper, green onion, and a tablespoon of vinaigrette per serving. The oil adds ~120 calories per tablespoon to the bowl total, so measure rather than eyeball.

Meal Planning Swaps

• Swap for refined starch: Replace 1 cup of white rice with 1 cup of these peas to gain protein and fiber while keeping calories in the same ballpark.
• Half-and-half bowls: Mix equal parts peas and brown rice; the texture pops, and the overall calories stay predictable.
• Veg-heavy plates: Pair a ½-cup scoop with a double serving of non-starchy vegetables for a hearty plate that still fits most calorie budgets.

Evidence Corner: Where The Numbers Come From

Calorie and macro values are drawn from datasets that compile laboratory analyses of cooked mature cowpeas. The nutrient snapshot for a 1-cup cooked portion aligns closely across independent aggregators that publish FoodData Central–based entries for black-eyed peas (the best match for purple-hull types). See the cooked entry showing ~198 kcal, ~13 g protein, and ~11 g fiber per cooked cup. Cooked black-eyed peas nutrition

Practical Takeaway

Plan around ~200 calories per cooked cup for these cowpeas. Keep fat additions measured, rinse canned varieties, and choose portion sizes that match your goals. That way, you enjoy the earthy flavor, plus the protein and fiber, without guesswork.
