Poblano Peppers Origin

poblano peppers origin map

Like the Jalapeno plant, Poblano peppers are from the Capsicum annum family of chiles. The name “Poblano” comes from the word “Puebla” — a state in Mexico where these peppers originated.

Many food experts believe that these peppers were probably an important food staple in the diets of many people in South America, including the ancient Aztecs [source].

Poblano peppers can be up to six inches long and three inches wide with a roomy interior ideal for stuffing (think cheese, ground beef, shrimp — yum!). The immature Poblano color is dark green, but they’ll turn deep red and brown if you leave them on the plant.

In fact, when Poblano peppers are allowed to ripen to red and dried, they’re called chile Ancho. The Mulato pepper (also dried) is a Poblano that matures even further to brown.

Note: You’ll sometimes see Poblano peppers incorrectly called Pasilla, but the Pasilla pepper is a different type of chile.

And how do you pronounce “Poblano”? It’s how you might imagine: poe-BLAH-no, with the accent on the middle syllable.

Poblano Peppers Scoville

how hot are poblano peppers in Scoville Heat Units (chart)

The Poblano pepper’s Scoville (SHU) rating is 1,000 to 1,500 SHUs, so they do have a tiny bit of heat. On the Scoville scale, peppers in this range are considered mild.

Red Poblanos tend to be spicier because they’ve had more time on the vine.

Chile Poblano is spicier than a Bell pepper, which has a zero Scoville rating. However, Jalapeño peppers go up to 8,000 SHUs, so Poblanos are much milder in comparison.

What Do Poblano Peppers Taste Like?

The Poblano is a mild pepper with flavors that are sweet, earthy, with just a hint of spice. The taste is similar to a green Bell pepper (a no-heat chile), but the Poblano pepper is not as sweet.

Fresh Poblanos differ from their counterparts — the Ancho (dried red pepper) and Mulato (dried brown pepper). The Poblano is more vegetal-tasting, whereas the Ancho and Mulato have rich, in-depth smoky flavors that include fruit, coffee, and chocolate notes.

How To Roast Poblano Peppers 3 Ways

how to roast poblanos recipe

While you can eat Poblano peppers raw, you’ll want to roast these chiles before using them in recipes — they taste better this way too!

There are three basic ways to roast Poblano chiles: On the stovetop using a cast iron skillet or comal, broiling in the oven, or flame-roasting on a gas stove.

After roasting Poblanos, you need to steam, or “sweat,” the peppers to remove the skin. Sweating softens chiles, draws out the Poblano flavors, and makes peeling the skin easier. (Roasted Poblano chiles need to have the skin peeled.)

The following tutorial covers three techniques for roasted Poblano peppers — choose one of the roasting methods, then scroll down to learn how to sweat the peppers once they’re roasted.

Poblano Pepper Alternatives

Poblano pepper alternative: Cubanelle pepper
Cubanelle Pepper

Because of their increased popularity, Poblano peppers are easy to find in most parts of the U.S. However, if you still can’t find them, below are some worthy substitutes.

  • Anaheim pepper: You’ll also see Anaheim peppers called California chile peppers. With a Scoville rating between 500 and 2,500 SHUs, the heat is comparable to Poblanos, but many Anaheim peppers lean towards the high end, so they can be a bit spicier.
  • Bell pepper: You can use Bell peppers (in equal ratios) for most recipes that call for Poblano peppers. A Bell pepper has a Scoville of zero (so no spiciness), with a similar texture and thicker, sturdier walls than Poblanos.
  • Cubanelle pepper: Like the Poblano, the Cubanelle pepper is a sweet pepper, but it can also provide a little bit of heat — still milder than a Poblano — with the potential to have up to 1,000 SHUs. Cubanelles are about the size of a Poblano pepper, so you can substitute them one-for-one or use two if the Cubanelle peppers are smaller.
  • Pasilla pepper: A Pasilla pepper can range from 1,000 to 2,500 SHUs, so there’s the potential to get a spicier pepper for your recipe. Use one or two Pasilla peppers to replace a Poblano chile.
  • Jalapeño pepper: The Jalapeno pepper is another alternative to Poblanos if you don’t mind more heat. (To reduce the spiciness of a Jalapeño, remove the seeds and veins, then rinse them under cold water before using them in a pepper recipe.) Because of their size, you’ll need three to five Jalapeño peppers when subbing them for Poblanos.
  • Ancho chile: If you’re making a mole sauce, go with chile Ancho, which is made from fully ripened Poblanos that have been dried. Follow your mole recipe to know how much chile Ancho to use.

Storing Poblano Peppers

Storing Poblanos In Refrigerator

Whole, unwashed raw Poblano peppers can be stored in your refrigerator’s crisper drawer for up to two weeks. I don’t recommend washing your pepper before you store them. Rather, wash the peppers right before you use them.

If you have extra Poblanos and want to have some for future recipes, pop them into a freezer bag. Frozen peppers last up to eight months and are handy to have for quick recipe additions.

You can also freeze prepared Poblano peppers. The freezer will affect the texture somewhat, so keep this in mind.

Canning Poblanos is another great way to preserve them. When you can peppers, the texture holds up much better than it does using the freezer method.

How To Grow Poblano Peppers

Here’s an overview of the growth stages for growing Poblanos:

When To Plant Peppers: Start pepper seeds indoors about eight weeks before the last frost date in your zone. (If you live in a cold climate, start your seeds 8-10 weeks before the last frost date so your seeds have a head start.) Poblano seeds typically germinate in six to 10 days after planting.

Seed Planting: Sow your Poblano seeds 1/4 to 1/8 inches deep in a slightly-damp seed-starting mix, putting two seeds into each pot to ensure you’ll get a sprout. Cover the containers and put them on a plant heat mat so they remain at the optimal 80 to 90°F temperature (27 to 32°C) for germination. Water the mix from the bottom to keep the soil hydrated.

Indoor Seedlings: Use a plant grow light once your seeds have germinated, keeping the seedlings underneath the light for 14-16 hours a day. Use a 1/4-strength fertilizer for pepper plants after the first set of true leaves emerges. Poblano seedlings need to stay inside for about two months before they can be planted outdoors.

Prepare For Outdoors: Transplant pepper seedlings into larger pots so your Poblano plants can continue growing (about 3 to 4 weeks after germination). After nighttime temperatures are above 55°F (13°C) and the last expected frost date has passed, begin hardening pepper plants to get them acclimated to the outdoors.

Fruiting Plants: Most pepper plants thrive with well-drained soil and full sun—eight hours a day is ideal—and Poblanos are no different. When tiny flowers begin to appear on your Poblano plants, you can start expecting peppers in a couple of months. When can you pick Poblano peppers? Generally, you can harvest Poblano peppers 70 to 80 days after you transplant them outdoors.
