How to Grow Cubanelle Pepper From Seed

Updated July 2026

Cubanelle is the classic Italian frying pepper: long, tapered, thin-walled fruit that starts a pale light yellow-green and ripens to red. It is sweet and mild, with at most a whisper of warmth, and it fries up sweet and silky in olive oil. Fast to mature and productive, it is a kitchen-garden staple for sandwiches and skillet dishes. Here is how to grow it well.

Quick start

Start seeds indoors about 8 weeks before your last frost, kept warm at 75 to 85F. Harden the plants off, then transplant them out 18 to 24 inches apart once nights stay above 55F. Give full sun, steady water, and a stake or cage to support the long fruit. Pick peppers light yellow-green from about 65 to 70 days for frying, or let them ripen red for a sweeter flavor.

Best tip

Cubanelle is an easy, productive Italian frying pepper that sets fruit well even when nights are cool, but it still loves heat once established. Start seeds indoors early and transplant after nights stay above 55F. Because the fruit is long and the plants get heavy, give them a stake or cage; pick the peppers young and light yellow-green for frying, or wait for them to blush red for a sweeter, richer flavor.

Uses

Cubanelle is the classic frying pepper, thin-walled and sweet with just a whisper of mildness. It is unbeatable sauteed in olive oil for sandwiches, sausage-and-peppers, and Italian and Latin dishes, and it softens beautifully because of its thin skin. Use it fresh and light-green for a crisp frying pepper, or let it ripen red for a sweeter, deeper taste in sauces and skillets.

Frequently asked questions

How long does Cubanelle take to mature?

Cubanelle is fairly quick for a pepper, ready to pick light yellow-green at about 65 to 70 days from transplant, or around 80 days if you let the long fruit ripen to red for a sweeter flavor.

Is Cubanelle a hot pepper?

No, Cubanelle is a sweet, mild frying pepper. It registers very low on the Scoville scale, roughly 100 to 1000 units, so at most it has just a faint warmth and is far milder than a jalapeno.

What size and color are Cubanelle peppers?

The fruit is long and tapered, about 5 to 6 inches, with thin walls. It starts a pale light yellow-green, which is the classic frying stage, and ripens through orange to red if left on the plant.

What is the best way to use Cubanelle peppers?

Cubanelle is the classic Italian frying pepper. Sauteed in olive oil it becomes sweet and silky, perfect for sandwiches, sausage-and-peppers, and Latin and Italian dishes. Its thin walls also make it good for roasting.

When are Cubanelle peppers ready to pick (green vs red)?

Pick them green and glossy at full size for their classic mild, sweet flavor, or leave them to ripen through yellow-orange to red for a sweeter taste. Both are edible, and picking regularly once they reach full size keeps new peppers coming.
