How Many Calories Are In Baked Pumpkin Seeds? | Quick Snack Facts

Calories In Roasted Pumpkin Seeds By Serving

Let’s pin down the range first. Dry-roasted, shelled seeds (pepitas) average around 150–170 calories per ounce. That lines up with USDA data for roasted kernels, where 100 grams land near the mid-500s for calories; scaled to 28 grams (1 ounce), you get the familiar mid-hundreds. Whole seeds with shells trend lower per ounce because the inedible hull adds weight.

The table below turns that range into real-world scoops. Use it to portion snacks or toppings without pulling out a scale.

Serving	Shelled, Dry-Roasted (kcal)	In Shell, Dry-Roasted (kcal)
1 tablespoon (~9 g)	50–55	40–45
2 tablespoons (~18 g)	100–110	80–90
1 ounce / 28 g	155–165	120–135
1/4 cup shelled (~28 g)	155–165	—
1/2 cup shelled (~56 g)	310–330	—
1 cup shelled (~129 g)	700–730	—

Label math uses 1 ounce as 28 grams, which aligns with FDA serving size conventions for weight-based foods. When packages use cups or tablespoons, that’s a household measure mapped back to grams on the nutrition panel. For background, check the FDA guide to serving sizes.

Portion targets shift with your day. If a light sprinkle is all you want, aim for a tablespoon. Building a snack? Two tablespoons deliver crunch and protein without overshooting calories. Snacks fit better once you set your daily calorie needs.

What Changes The Calorie Count When You Bake

Roasting drives off a bit of water and deepens flavor. The calorie figure doesn’t move much unless you add oil or sugar. A teaspoon of oil spread across a full cup adds about nine calories to each 1-ounce serving in that batch; a tablespoon adds roughly twenty-six per ounce. Heavy coatings swing the number faster than oven time.

Oil And Seasoning

A light coat—about one teaspoon per cup of seeds—keeps spices stuck and helps browning. More oil gives a richer crunch and bumps calories. Salt doesn’t add calories, but high-sodium blends do change the label. If sodium is a concern, go with plain dry-roasted or low-sodium spice mixes.

Shell-On Versus Shelled

Whole seeds weigh more for the same volume because of the hull. Calorie density per ounce looks lower, but you’ll get fewer edible kernels. If you crack and spit shells, the portion pace naturally slows. If you chew and swallow shells, count more fiber and a bit more volume in your plan.

Oven Time And Temperature

Moderate heat keeps nutrients intact while still getting a crisp bite. Peer-reviewed work on pumpkin seeds notes that roasting changes some antioxidants but doesn’t wipe out the core nutrition; flavor improves while the fatty acid profile stays fairly stable. For home batches, dry-roast at 160–175°C (320–350°F) for 12–18 minutes, tossing once, and pull when browned and fragrant. See this review on roasting effects.

How To Bake Pumpkin Seeds For Predictable Calories

Here’s a simple, repeatable method that nets consistent portions and reliable numbers.

Prep And Dry

Rinse well, remove stringy bits, and pat dry. Surface moisture delays browning and can make seasoning patchy. If you’re using bagged pepitas, you can skip to seasoning.

Season Smart

For plain dry-roasted seeds, use spices only. For oiled versions, measure one teaspoon of oil per packed cup, then add your spice blend. That rate keeps calories in check while still helping spices stick.

Roast Evenly

Spread in a single layer on a parchment-lined tray. Bake at 170°C / 340°F. Stir halfway. Taste a few; pull the tray when the color darkens a shade and the crunch sounds crisp.

Weigh Once, Then Scoop

After cooling, weigh the batch so you know total grams. Divide by your usual scoop—say 28 grams for an ounce—to set how many servings you made. Next time, you can skip the scale and use the same scoop.

Nutrition Snapshot Beyond Calories

Pepitas bring protein, healthy fats, and fiber in a small space. One ounce of dry-roasted kernels lands near 8 grams of protein, roughly 14 grams of fat, and a couple grams of carbs with fiber. You’ll also get minerals common to nuts and seeds, including magnesium and zinc.

Nutrient	About Per Ounce	Why It Helps
Protein	~8 g	Helps satiety; supports muscle repair.
Total Fat	~14 g	Mostly unsaturated; steady energy.
Fiber	~2 g	Slows digestion; pleasant crunch.
Carbs	~4 g	Low impact for small portions.
Magnesium	Seeds are a source	Linked to nerve and muscle function.

On minerals, U.S. agencies point to nuts and seeds as sound sources of magnesium. If you want the science detail, skim the NIH magnesium fact sheet. For calorie baselines and gram weights, the most direct database is USDA FoodData Central.

Buying And Label Tips

Shelled Versus Whole

Shelled kernels (pepitas) list higher calories per ounce because every gram is edible. Whole seeds may show a lower number per ounce due to the hull, but once you crack them, the edible part lines up closely with the shelled numbers.

Dry-Roasted Versus Oil-Roasted

Dry-roasted kernels keep the number tidy and predictable. Oil-roasted snacks vary by brand; check grams of fat per serving to see how much oil was added. An extra 2–3 grams of fat per ounce explains a 20–30-calorie bump.

Sodium Flags

Spiced or salted mixes aren’t a calorie issue, but labels can jump in sodium. If that matters to you, look for low-sodium seasonings or roast at home with citrus, herbs, and pepper.

Portion Scenarios That Work

Quick Breakfast Topper

One tablespoon over oats or yogurt adds around fifty calories and a bit of protein. That little boost holds you longer without a heavy bite.

Desk Snack

Two tablespoons in a small container make a tidy 100- to 110-calorie nibble. Add a mandarin or a cup of berries, and you’ve got a balanced break.

Salad Crunch

A rounded tablespoon brings texture without tipping the bowl into meal territory. Toast with smoked paprika for a savory lift.

Storage And Freshness

Keep seeds in a cool, dark spot in an airtight jar. For longer storage, freeze in small bags; fats stay fresh and the crunch holds. Season right before roasting or serving to keep spices bright.

Simple Oven Method With Numbers

Ingredients

• 2 cups raw pumpkin seeds (pepitas or shell-on)
• 2 teaspoons neutral oil (optional)
• 1 teaspoon fine salt (or to taste)
• Spices: paprika, garlic powder, black pepper

Method

1. Heat oven to 170°C / 340°F. Line a sheet pan.
2. Pat seeds dry. If using oil, toss 1 teaspoon per cup with spices and salt.
3. Spread in a single layer. Bake 12–18 minutes, stirring once.
4. Cool on the pan. Weigh the batch; divide by 28 g to count ounce-size servings.

Per-Serving Estimate

With no oil: about 155–165 calories per ounce (shelled). With 1 teaspoon oil per cup: add roughly 9 calories per ounce. With 1 tablespoon oil per cup: add roughly 26 calories per ounce.

Bottom Line On Portions

An ounce of dry-roasted pepitas lands near the mid-hundreds for calories. Small scoops—one to two tablespoons—give crunch and nutrition without crowding your meal plan. If you want a full walkthrough of energy budgeting, try our calorie deficit guide.
