How Many Calories Are In Red And Green Bell Peppers? | Quick Facts Guide

Calories In Red And Green Bell Peppers By Portion

Bell peppers are light on energy yet generous with water, fiber, and micronutrients. Color changes taste and vitamin profile a bit, but not the basic calorie math. Use the chart below to size portions for meal prep, snacks, or recipes.

Color & Form	Typical Serving	Calories
Green, raw	100 g (about 1 cup chopped)	~20 kcal
Red, raw	100 g	~26 kcal
Green, raw	1 cup chopped (149 g)	~30 kcal
Red, raw	1 medium (≈119 g)	~31–35 kcal
Red, boiled	1 cup strips (135 g)	~38 kcal
Red, sautéed (with oil)	100 g	~133 kcal

Numbers above reflect standard database entries compiled from USDA-cited datasets and meal-size forms. Green tends to be lowest per gram; red is a touch higher, mainly due to natural sugars developed during ripening. Cooking method matters more than color, which is why oil-heavy skillet batches climb quickly.

What Changes Between Colors?

Green peppers are simply unripe versions of the sweeter red stage. The calorie gap is small, but vitamin levels shift. Red usually carries more vitamin A and plenty of vitamin C. Green brings lots of vitamin C too, with a slightly grassier taste that suits stir-fries and omelets.

Both colors are standout sources of vitamin C relative to calories. A medium green pepper can land near 120 mg per cup chopped, while a medium red pepper often reaches 150 mg or more depending on size and cut. That’s already above the daily value set for adults. For reference, see the NIH vitamin C fact sheet for current DV context and bioavailability notes. Mid-week grocery planning gets easier when you know a single pepper can cover your needs without denting calories.

Serving Sizes You’ll See On Labels

Databases commonly show both weight-based and household servings. You’ll see “100 g,” “1 cup chopped,” or “1 medium.” Those aren’t interchangeable in weight, so expect small shifts. One medium pepper often lands near 119–164 g depending on variety and database entry. When precision matters—like tracking—pick a consistent serving unit for all your pepper entries.

How Cooking Affects The Count

Roasting adds almost no energy if you keep oil off the tray. Sautéing is different: a tablespoon of oil brings roughly 119 kcal on its own. That’s why a quick skillet batch can jump from diet-friendly to dense in a few minutes. If you love the gloss and flavor, measure the pour or finish with a small drizzle at the end instead of frying in oil from the start.

Fiber, Hydration, And Satiety

Peppers are mostly water with a couple grams of fiber per cup. That combo fills the plate and helps you feel satisfied on fewer calories. If you’re balancing meals around whole foods, peppers plug in easily next to protein and grains. They also pair well with hummus or yogurt dips for a crisp snack. If you track fiber intake, this veggie gives you steady progress toward your recommended fiber intake.

Smart Swaps And Pairings

Use peppers as volume boosters in bowls, tacos, and pasta. Swap half the noodles for sautéed strips (minimal oil) to bring calories down while keeping portion size up. Add a handful of chopped peppers to scrambled eggs or tofu for color and crunch without much energy cost. In salads, combine red and green for sweetness plus bite; sprinkle seeds or nuts for texture and use a measured vinaigrette to keep the dressing in check.

What About Micronutrients?

Alongside vitamin C, peppers supply vitamin B6 and potassium in modest amounts, with carotenoids concentrated more in red. If you want a quick seasonal overview, the USDA bell peppers guide outlines buying tips and storage basics. Keep peppers cold and dry; use within several days for the best crunch.

Detailed Calorie Notes By Preparation

Below is a compact reference for common ways to cook peppers. The first two rows show raw baselines you can use when weighing or measuring. The rest highlight why technique—especially added fat—drives the biggest swings.

Method	Per 100 g	Vitamin C (typical)
Green, raw	~20 kcal	~80–120 mg per 100–150 g
Red, raw	~26 kcal	~127–152 mg per 100 g
Red, boiled (no oil)	~28–38 kcal	~200+ mg per cup strips
Red, roasted (no oil)	~25–35 kcal	High, with some heat loss
Red, sautéed (oil)	~133 kcal	Good, but depends on time/heat

Practical Tips For Keeping Calories Low

• Roast on parchment with just a spray of oil. Toss with a teaspoon of olive oil after cooking if you like sheen.
• Sweat peppers in a covered pan with a splash of water, then finish with a small pat of butter or oil for flavor.
• Use nonstick pans when stir-frying; measure oil with a teaspoon, not a free pour.
• Marinate sliced peppers in citrus or vinegar to boost taste without adding energy.

How To Read Pepper Entries In Nutrition Databases

Databases pull from multiple USDA datasets and recipe forms. When you search, watch the food name and form: “raw,” “boiled,” or “sautéed.” Check the serving unit too. “1 medium” and “1 cup chopped” won’t match the same grams. For tight tracking, weigh raw portions before cooking, then add any oil separately. This keeps logs honest and comparable from week to week.

Quick Comparisons You Can Use

• Snack plate: 1 cup raw green (~30 kcal) vs. 1 cup raw red (low 30s). Taste decides; energy barely changes.
• Skillet fajitas: measure oil; that’s the lever. The peppers themselves stay light.
• Pasta night: swap 1 cup pasta for 1 cup roasted pepper strips to trim energy and add color.

FAQ-Free Bottom Line

Color brings personality more than calories. Green leads by a hair for the lowest number per gram, while red brings sweeter flavor and stronger carotenoid content. Both offer standout vitamin C for minimal energy. Keep an eye on cooking fat and you can load plates with peppers every day.
