How many calories in a red roasted pepper?

Quick Answer

A medium red roasted pepper contains around 40 calories. The exact calorie count can vary slightly depending on the size of the pepper and how it is prepared. But in general, a medium roasted red pepper provides about 40 calories, 9 grams of carbohydrate, 2 grams of fiber, and almost 150% of the daily recommended intake of vitamin C.

Calorie Count Factors

Several factors affect the calorie content of roasted red peppers:


Larger peppers contain more calories and smaller peppers contain fewer calories. For example:

– A small roasted red pepper (around 3 inches long) contains about 25 calories
– A medium roasted red pepper (around 4 inches long) contains about 40 calories
– A large roasted red pepper (over 5 inches long) contains about 50 calories

So the bigger the pepper, the more calories it will provide.

With or Without Seeds/Membrane

Peppers with the seeds and inner white membranes intact contain slightly more calories than seeded peppers with the membranes removed. The seeds and membranes provide an extra 2-3 calories per pepper.

Roasting Method

How the red pepper is roasted also impacts its calorie content. Red peppers roasted in oil or broiled with oil will contain slightly more calories than raw red peppers or those roasted without oil. The oil adds minimal extra fat and calories.

Added Ingredients

If additions like cheese, garlic, herbs, or breadcrumbs are added to stuffed roasted red peppers, the calorie count will increase accordingly. Plain roasted peppers have the lowest calories.

So the calorie content ranges based on these factors, but a medium 4 inch long red pepper roasted without oil or other additions provides about 40 calories.

How to Roast Red Peppers

You can easily roast red peppers at home with these simple steps:


– 3-4 red bell peppers
– 1 teaspoon olive oil (optional)
– Salt and pepper to taste


1. Preheat oven to 425°F. Line a baking sheet with parchment paper.

2. Wash peppers and pat dry. Remove stems and seeds. Rub peppers lightly with olive oil if desired.

3. Place pepper skins side up on prepared baking sheet. Season with salt and pepper.

4. Roast for 20-30 minutes until skins blister and turn black.

5. Remove from oven and immediately transfer peppers to a bowl. Cover with plastic wrap or lid and let sit 10-15 minutes. The steam will loosen skins.

6. Once cool enough to handle, peel off and discard skins. Slice peppers into strips.

7. Enjoy roasted red peppers on salads, sandwiches, pizzas, pastas, and more! Refrigerate leftovers.

Roasting the peppers intensifies the sweet flavor while charring the skins makes them easy to peel off. Adjust roasting time based on the size of your peppers. Smaller peppers may only need 15-20 minutes.
