In the poblano vs anaheim vs jalapeno question, the short answer is that the Anaheim and poblano are both mild, with the Anaheim usually a touch brighter and sweeter, while the jalapeño is clearly the hottest and grassiest of the three. All three are sold green in most shops, but they behave very differently once they hit a hot pan, an oven or a blender.
Key takeaways
- Jalapeños are the hottest of the trio; Anaheims and poblanos sit at the gentle end of the scale.
- Poblanos are broad, thick-walled and earthy, which makes them the classic stuffing pepper.
- Anaheims are long, thin-fleshed and fruity, and are excellent roasted and peeled.
- Heat varies from pepper to pepper, so taste a small piece before you commit to a whole recipe.
Heat levels in plain terms
Chilli heat is usually described using the Scoville scale, which grades peppers in Scoville heat units (SHU). You can read how the scale works on Wikipedia’s Scoville scale article. Commonly quoted ranges put the Anaheim and poblano in the low hundreds to low thousands of SHU, while the jalapeño typically reaches several thousand. The exact numbers differ between sources, so treat them as a guide rather than a promise.
What matters in the kitchen is the rank order. Poblano and Anaheim feel warm rather than fiery, and many people with a low tolerance for chilli can eat them without trouble. A jalapeño can be gentle or surprisingly sharp, even within the same batch, because growing conditions, ripeness and the amount of white pith all change the heat.

The poblano: the stuffing pepper
The poblano has thick walls and a roomy cavity, so it holds fillings well. It is the pepper behind chiles rellenos, where it is roasted, peeled, filled with cheese or meat and then coated and fried or baked. Roasting brings out a deep, almost smoky flavour that raw poblano lacks.
When a poblano is left to ripen to red and then dried, it is known as an ancho, a staple of dried-chilli sauces. That is a useful fact if you spot “ancho” on a recipe and wonder whether it is related. It is the same plant, treated differently.
How to prepare a poblano
- Char the whole pepper over a gas flame, under a hot grill or on a very hot pan until the skin blisters and blackens.
- Put it in a covered bowl for ten minutes so the steam loosens the skin.
- Peel off the skin, slit the pepper open and remove the seeds and stem.
- Slice into strips for fajitas and soups, or leave whole for stuffing.
The Anaheim: gentle, sweet and versatile
The Anaheim is long and slender with thinner flesh, which makes it easy to roast and peel. Its flavour is fresh and slightly fruity, and the heat is usually low enough that it can be used generously. It is a good everyday pepper for green chilli stews, quesadillas and salsas where you want flavour without too much burn.
Because the walls are thinner than a poblano’s, an Anaheim can collapse if you stuff it with a heavy filling. It does better chopped into a dish or filled lightly. If you cannot find Anaheims, the pepper is sometimes sold under other names, such as long green chilli or New Mexico green chilli, though those can be a little hotter.
The jalapeño: the everyday kick
The jalapeño is the pepper most shoppers recognise. It is small, crisp and quick to prepare, and it works raw, pickled, grilled or stuffed. Most of the heat lives in the white membrane and seeds, so removing them tames the pepper considerably. Leave them in for a fiery salsa or a hot sauce.
Smoked and dried jalapeños are called chipotles, which add a deep, smoky heat to marinades and sauces. If you enjoy cooking with oil at high heat, such as frying jalapeño poppers, our guide to deep fryer oil temp explains how to keep the coating crisp rather than greasy.
Swapping one for another
These peppers are not perfectly interchangeable, but you can get close with a few adjustments.
- Anaheim for poblano: a good swap in soups, sauces and stews. For stuffing, choose the widest Anaheims you can find and fill them lightly.
- Poblano for Anaheim: works well, but expect a darker, earthier taste.
- Jalapeño for either: use about half the quantity and remove the seeds and membranes, then taste and add more if needed.
- Either mild pepper for jalapeño: you will lose the heat, so add a pinch of chilli flakes or a little hot sauce.
Recipes that call for ingredients you may not have often have sensible alternatives. For a similar example outside the chilli aisle, see our guide to what is in matzo meal and its substitutes.
Handling and safety tips
- Capsaicin, the compound that makes peppers hot, sticks to skin. Wear disposable gloves when cutting jalapeños, especially in bulk.
- Wash the knife, board and your hands with soap and warm water afterwards, and keep your hands away from your eyes.
- If your mouth burns, milk, yoghurt or a spoonful of sugar tends to help more than water.
- Choose firm, glossy peppers with smooth skin, and store them unwashed in the fridge.
Frequently asked questions
Which is hotter, a poblano or an Anaheim?
They overlap, and individual peppers vary. Generally, both are mild, and either can feel a little warmer than the other depending on the plant and how ripe the pepper is.
Is a jalapeño much hotter than a poblano?
Yes, on average. Jalapeños typically reach several times the heat of a poblano, though a mild jalapeño can come close to a spicy poblano.
Do I need to peel poblanos and Anaheims?
Usually, yes, if you are roasting them. The skin is tough and can curl up in a dish. Roasting and steaming the peppers makes peeling easy. Jalapeños are normally used with the skin on.
What is the best pepper for chiles rellenos?
The poblano is the traditional choice thanks to its size and sturdy walls. Large Anaheims can be used if poblanos are unavailable.
How do I make a jalapeño less spicy?
Cut it open, scrape out the seeds and white pith, and soak the pieces in cold water or a little vinegar for ten to fifteen minutes before using.
Conclusion
Choosing between these peppers comes down to heat tolerance and the job at hand. Reach for a poblano when you want to stuff or add smoky depth, an Anaheim for a sweet, gentle roast, and a jalapeño when you want a lively kick. Once you understand the poblano vs anaheim vs jalapeno differences, swapping between them stops being guesswork and becomes a matter of taste.
