Poblano
Poblanos are mild chili peppers adding earthy sweetness when roasted or cooked.
The poblano is a large, heart-shaped, dark green chilli from Puebla in Mexico. It has thick walls, a mild and gentle heat, and an earthy, green, slightly bitter flavour that turns deep, sweet and smoky once the skin is charred. Dried, the ripe red poblano becomes the ancho chilli.
Cooks love it because it is a chilli you can eat in quantity. It is big enough to stuff for chiles rellenos, mild enough to slice into creamy rajas or blend into a green rice, and sturdy enough to grill, roast or simmer in soups and stews without falling apart.
Flavor profile
Aroma: mildly spicy, earthy
Good to know
Origin: Mexico
Forms: fresh, dried as ancho
Season: Available year-round; local poblanos are at their best from late summer to early autumn.
Nutrition: Like other peppers, poblanos are a colourful vegetable that adds vitamins and fibre to a meal.
Storage: Wrap whole poblanos in paper towel and keep them in a loosely sealed bag in the crisper drawer for up to 1–2 weeks. Roasted and peeled poblanos keep in a sealed container in the fridge for about 5 days. They freeze very well after roasting: peel, seed, lay flat in bags and freeze for up to 6 months, ready for sauces, soups and rajas. Throw out any that turn soft, slimy or mouldy.
How to use poblano
Roast for Richness
Roasting enhances their natural sweetness by converting sugar to caramel.
Stuffed Peppers
Bake to soften and merge flavors in stuffed poblanos.
The science of poblano
- Poblanos contain only a little capsaicin, usually about 1,000–2,000 Scoville heat units. That is enough for a soft warmth, though the occasional pepper is noticeably hotter, so taste a strip before adding a whole one.
- Charring the skin over a flame or under the grill blisters it, separating the tough outer layer from the flesh. Steaming the hot peppers in a covered bowl for 10 minutes lets moisture loosen the skin even more so it slips off easily.
- The smoky, sweet flavour of roasted poblano comes from the Maillard reaction and caramelisation on the blackened surface, plus the softening of cell walls as pectin breaks down, which releases sugars and juices.
- Its green, slightly bitter edge comes partly from methoxypyrazines, the aroma compounds also found in green bell pepper. Salt and fat soften the bitterness, which is why poblano and cream or cheese work so well together.
How to choose poblano
Choose glossy, very dark green peppers that feel firm and heavy, with smooth skin and fresh green stems. Flatter, straighter peppers are easier to char evenly and stuff. Avoid soft spots, wrinkles or dark wet patches.
Substitutes for poblano
| Swap | Amount | What changes |
|---|---|---|
| Anaheim pepper | 1:1 | Similar mild heat and size, with thinner walls and a slightly sweeter flavour. |
| Green bell pepper + a pinch of chilli | 1:1 | Gets the size and green flavour; add a little jalapeño or chilli flake for warmth. |
| Cubanelle | 1:1 | Very mild and sweet; good for stuffing and frying. |
| Canned roasted green chillies | about 1 small can per 2 poblanos | Handy for soups, sauces and casseroles, but too soft to stuff. |

Poblano: questions
How hot is a poblano pepper?
Poblanos are mild, usually around 1,000–2,000 Scoville heat units, well below a jalapeño. Every so often you will find a hotter one, so taste before you commit.
Do you have to peel poblano peppers?
The skin is tough and slightly bitter, so peeling is worth it for rellenos, rajas and sauces. Char the pepper, steam it in a covered bowl, then rub the skin off; do not rinse it under water or you lose the smoky flavour.

Char them directly over a gas flame, on a grill or under a hot oven grill, turning until blackened all over. Then cover in a bowl for 10 minutes, peel, and remove the seeds and stem.
