What is Red Pepper?
Red Pepper is the ripe, sweet-fleshed form of the bell pepper, with glossy red skin and a hollow centre. It is crisp and juicy raw, then turns tender and sweeter when cooked. Across many cuisines it is sliced into salads, roasted for dips and sandwiches, or added to stews, stir-fries and stuffed-pepper dishes. Its mild flavour works well with herbs, garlic, tomatoes and grains, so it can fit into everyday meals without overpowering them.
It is a low-calorie vegetable that provides vitamin C and fibre. Pair it with beans, eggs or another protein for a more filling meal, or roast it and serve with a little olive oil and lemon for a simple side.

Frequently Asked Questions About Red Pepper
Is red pepper the same as a bell pepper?
Red pepper can mean different things, but the sweet, hollow vegetable shown here is a red bell pepper. In recipes, “red pepper” may also refer to hot chili pepper, so check whether the recipe means sweet or spicy.
Can you eat red pepper raw?
Yes, you can eat red pepper raw. Rinse it under running water, remove the stem and inner seeds if you prefer, then slice it for salads, sandwiches, or a crunchy snack.
How should you store red pepper?
Keep red pepper dry and unwashed in the refrigerator’s crisper drawer, ideally in a bag or container that allows some airflow. Wash it just before use, since trapped moisture can make the pepper spoil sooner.
Can you freeze red pepper?
Yes, red pepper freezes well for cooked dishes. Wash and dry it, remove the stem and seeds, then chop or slice it and freeze in an airtight bag. Its texture softens after thawing, so it is less suitable for salads.
How do you roast and peel red pepper?
Roast red pepper under a broiler, over a flame, or on a grill until the skin is blistered and charred in spots. Cover it briefly while warm to loosen the skin, then peel it off before serving.
Do you need to remove the seeds from red pepper?
No, removing red pepper seeds is not necessary; they are edible. Many cooks take them out because the seeds and pale inner ribs can feel bitter or affect the texture. Cut around the core to remove them quickly.
Why does red pepper turn red while green pepper stays green?
A green pepper is often an unripe version of a red pepper. As it matures on the plant, it changes color and develops a sweeter flavor. Some pepper varieties, however, remain green or ripen to other colors.
How can you tell if a red pepper is fresh?
A fresh red pepper feels firm and heavy for its size, with taut, glossy skin and a green-looking stem. Avoid peppers with soft spots, wrinkles, mold, or a shriveled stem, which are signs of age or damage.
Can dogs eat red pepper?
Yes, dogs can generally eat small pieces of plain red bell pepper. Remove the stem and seeds, cut it into bite-size pieces, and avoid seasoning, oil, or spicy chili peppers, which are not the same as sweet bell peppers.
Why does red pepper taste sweeter than green pepper?
Red pepper has had longer to ripen on the plant, so its flavor is usually sweeter and less grassy than green pepper. The exact taste varies by variety, and a red pepper can still taste mildly sharp.
