Cubanelle Pepper: Sweet, Thin-Walled, and Nearly Heatless at 100–1,000 SHU

What Is Cubanelle Pepper Known For?

Walk through any Italian neighborhood market in New York or a Cuban home kitchen, and you will almost certainly find cubanelles. This C. annuum variety has been embedded in both Caribbean and Italian-American food traditions for generations, not because it brings heat, but because it brings flavor.

The pods are elongated and slightly tapered, typically 4 to 6 inches long, with thin, waxy walls and a hollow interior. Fresh cubanelles start pale yellow-green and ripen through orange to red.

Most cooks pick them before full maturity, when the flesh is crisp and the flavor is clean and mildly sweet.

At 100 to 1,000 SHU, a cubanelle registers so low on the Caribbean chile tradition spectrum that heat is essentially a non-factor. Compare that to a chipotle, which can reach 2,500 to 8,000 SHU - the cubanelle is many times milder.

This makes it genuinely accessible to people who want pepper flavor without any burn.

The thin walls set it apart from bell peppers in a practical way: cubanelles soften faster when cooked, blister beautifully under high heat, and absorb surrounding flavors without turning mushy. That's why they're the go-to for Italian frying peppers and Cuban sofrito bases alike.

Botanically, it belongs to Capsicum annuum, which also includes jalapeños, poblanos, and bell peppers, a remarkably diverse family.

What Is the Origin of Cubanelle Pepper?

The cubanelle takes its name from Cuba, where it has been cultivated for centuries as part of the island's essential cooking trinity alongside onion and garlic. Cuban immigrants brought it to the United States, particularly to New York and Florida, where it became a fixture in Latin grocery stores long before specialty produce became mainstream.

Italian immigrants adopted the pepper enthusiastically, calling it the Italian frying pepper - a name that stuck in northeastern U.S. markets. Its thin walls and low moisture content made it ideal for the style of pan-frying central to Italian-American home cooking.

By the mid-20th century, cubanelles were appearing in seed catalogs across the eastern seaboard. Today they are grown commercially throughout the U.S. Caribbean, and Mediterranean, though their cultural roots remain firmly tied to Cuban and southern Italian traditions.

What Does Cubanelle Pepper Taste Like, and How Hot Is It?

The Cubanelle Pepper delivers 100–1K Scoville Heat Units, placing it in the Medium tier (1K-10K SHU).

Flavor notes: sweet and mild.

How Nutritious Is Cubanelle Pepper?

A 100-gram serving of raw cubanelle pepper contains approximately 27 calories, with minimal fat and about 6 grams of carbohydrates. Like most sweet peppers, it delivers a solid hit of vitamin C - often exceeding 100% of the daily recommended value when fully ripe and red.

The thin walls mean a higher water content than thick-walled varieties, which keeps calorie density low. Cubanelles also provide modest amounts of vitamin B6, folate, and potassium.

The low capsaicin content means no significant metabolic heat effect, unlike hotter varieties where capsaicin influences calorie burning.

How Do You Use Cubanelle Pepper in the Kitchen?

Cubanelles shine in high-heat applications where bell peppers fall flat. Toss them whole into a dry cast-iron skillet and let them blister, the thin skin chars quickly, the flesh softens, and the sweetness concentrates.

A little olive oil, salt, and garlic is all they need.

How Should You Buy and Store Cubanelle Pepper?

Cubanelles are most common in Latin and Italian specialty markets, though larger grocery chains in the Northeast and Florida carry them regularly. Look for pods that are firm with no soft spots, pale yellow-green to light green in color, and free of wrinkles, wrinkling signals age and moisture loss.

At home, store unwashed cubanelles in the refrigerator crisper drawer in a loosely sealed bag. They hold well for 1 to 2 weeks when kept dry.

For longer storage, roast and freeze them, they maintain flavor well frozen and thaw quickly for use in cooked dishes.

Avoid refrigerating below 45°F, which can cause chilling injury and pitting on the skin.

What Is a Good Substitute for Cubanelle Pepper?

Compare substitutes for Cubanelle Pepper by form, flavor, and heat before choosing a ratio. Measured adjustments must account for the dish and the concentration of the replacement.

Direct comparisons show where flavor, form, and preparation differ in the Cubanelle vs Poblano and Banana vs Cubanelle matchups.

How Do You Start and Grow Cubanelle Peppers?

Cubanelles are among the more forgiving peppers to grow, which makes them a good choice for gardeners who want reliable production without fussing over soil conditions. Start seeds indoors 8 to 10 weeks before last frost - pepper seed-starting and transplant timing after soil temperature reaches 65°F consistently gives them the best start.

Plants typically reach 24 to 30 inches tall and produce heavily once established. Days to maturity run around 65 to 70 days from transplant to green-stage harvest, which is when most cooks want them.

Leaving pods on the plant until red adds another 2 to 3 weeks but rewards patience with sweeter, more complex flavor.

They prefer full sun and well-drained soil with consistent moisture. Inconsistent watering leads to blossom drop and uneven fruit set.

A balanced fertilizer at transplant, then a switch to lower nitrogen once flowering begins, keeps plants productive without pushing excessive foliage.

Cubanelles are less cold-sensitive than many peppers but still need protection from late frost. In containers, they perform well in 5-gallon pots or larger.

Compare them to a choricero - both are relatively easy producers, but cubanelles bear fruit faster and require less babying through the season.
