Poblano peppers Nutrition facts

Poblano peppers, also known as Chile poblano, are perhaps the most popular peppers grown in Mexico. Early harvested and dried poblano, termed "ancho" (which means "wide"), are broad, flat, and heart-shaped peppers. Whereas, Mulato peppers are fully-matured, late-harvest, and dried poblanos.

Poblano peppers are botanically classified in the Solanaceae (nightshade) family.

Scientific name: Capsicum annuum var. annuum 'Poblano.'

Poblano pepper

Poblano peppers originating from Puebla, central Mexico. The plant is multiple-stemmed and compact to semi-erect, semi-woody, and about 25 inches high. It prefers a warm climate supplanted by fertile, well-drained soil to flourish.

The flowering begins 50 days after sowing and continues until the first frost. Soon, the pods appear, which are conical or truncated and have indented shoulders. They vary between 3 to 6 inches long and 2 to 2.5 inches wide.

Immature pods are smooth, shiny, and dark green, maturing to either red or brown, and the dried pods are very dark reddish-brown nearly black (Mulato peppers).

Poblanos are mild peppers that range between 1000-2000 Scoville units on the heat index. The pungent and fiery hotness of chili peppers comes from the capsaicin compound in them. The Scoville heat score is determined by the contents of capsaicin (in ppm) in all chile peppers in general.

8 Amazing Health Benefits of Tabasco Peppers

  1. Poblano peppers are mild, flavorful peppers with low calories and zero cholesterol. 100 g poblano carries just 12 calories and <1% of fats.

  2. They hold many phytochemical compounds such as capsaicin that have disease-preventing and health-promoting properties.

  3. Fresh Poblano peppers are excellent sources of vitamin C. 100 g fresh, green poblanos hold 80.6 or 123% of daily required levels of this vitamin.

  4. Vitamin C is a potent water-soluble antioxidant, required for collagen synthesis. It also plays a vital role in the prevention of viral diseases by boosting the anti-viral defense system in the human body.

  5. Poblanos are gluten-free, low-sodium peppers suitable for Gluten-sensitive and Celiac disease people.

  6. Poblano peppers contain an alkaloid compound, capsaicin, which gives them a mildly spicy character. Scientific studies suggest that the role of capsaicin has anti-bacterial, anti-tumor, analgesic, and anti-diabetic properties, at least in some early laboratory studies on experimental mammals. It was also found to reduce LDL-cholesterol levels in obese individuals.

  7. Poblano peppers compose other antioxidants such as vitamin A and flavonoids like β -carotene, α -carotene, lutein, zeaxanthin, and cryptoxanthin. Together, these compounds protect cells from injurious effects of free radicals generated by stress and various disease conditions.

  8. They are also a good source of B-complex vitamins such as pyridoxine, and thiamin, and minerals such as copper, calcium (10% DRI/100 g), and iron.

Fresh poblanos' peak season is summer and early fall. They are found in Mexican markets and in many supermarkets across the United States. They are also available canned in the groceries.

Choose firm, shiny, and fresh poblanos featuring firm stems from the farmers' markets. Fully grown, ripe poblanos turn reddish-brown and sweeter than raw green. Buy ancho/Mulato peppers in sealed packets from authentic sources.

Avoid dry, wilt, and pods with cracks, cuts, and surface bruising.


At home, store poblano peppers in a vegetable drawer inside the refrigerator set at high relative humidity. They keep well for up to a week when stored.

Roasted and peeled, poblanos can be preserved by either canning or deep-freezing.

Storing anchos in airtight containers will also suffice for several months. Anchos are often ground into a powder and used for flavoring recipes.

Preparation and serving methods

Poblanos are large, shiny, thick-skinned, and luscious peppers. They are subtly sweet and mild-hot, which is less than that of jalapeno.

Poblano is one of the most common chili peppers used in Mexican and in Southwestern U.S. cuisine. They can be prepared in a number of ways, commonly including, dried, breaded and fried, stuffed, or in sauces called moles.

In California, these chili peppers are often mistakenly addressed as chile pasilla, although pasillas are a distinct variety.

Poblano peppers are mild, broad, and conical-shaped papers and have very thick walls, which make them great for stuffing.

Except for stuffing, poblano papers are usually roasted and peeled before use.

Ancho chile peppers are deeply valued in traditional Mexican cuisine for adding color, flavoring, and mild spiciness.

When allowed to fully ripen and dry and shrivel, the poblanos are known as Mulato chile pepper. They add savory, sweet, and earthy flavors mixed with fruity undertones to the dishes.

Here are some serving tips:

Poblanos are very hot peppers. Do not overdo them when cooking because they compose very high amounts of the alkaloid compound capsaicin, which gives them a strong, pungent taste.


  • Poblanos can be used in a variety of dishes but perhaps best known as the chili of choice for chiles Rellenos (stuffed poblanos).

  • Roasted poblanos in cream sauce (Rajas con Crema) is a popular Central and Southern Mexican recipe.

  • Anchos are commonly used in sauces called moles.

Safety profile

  • Poblano peppers are categorized as mild peppers (1,000 to 1,500 on the Scoville scale of heat levels), characterized by low levels of capsaicin, which gives them a mild pungent character. However, in some sensitive persons, even a tiny bit of capsaicin can elicit irritation burning sensation, and inflammation in the mouth, tongue, and throat when coming in contact with the mucosa of the oral cavity, throat, and stomach.

  • Eating cold yogurt dilutes capsaicin concentration and thus may help reduce burning pain.

  • Avoid touching eyes with ancho-pepper-contaminated fingers. If so, rinse your eyes thoroughly with cold water to reduce irritation.

  • Unlike in other chili types, poblanos being mild peppers, may less likely to aggravate conditions such as gastritis, stomach ulcer, and gastro-esophageal reflux (GER) conditions.
