Pasilla Pepper: The Dried Chilaca With Raisin-Like Depth at 1,000–2,500 SHU
The pasilla pepper is a dried the chilaca pepper, prized in Mexican cooking for its 1,000-2,500 SHU warmth and deep, earthy richness. Grown as a long, dark green fresh chile, it transforms dramatically when dried, developing chocolate and dried-fruit notes that form the backbone of complex mole sauces.
A rewarding garden pepper with specific but manageable care requirements.

- Heat tier: Medium (1K-10K SHU)

What Is Pasilla Pepper?
Pasilla sits in the medium heat intensity range - warm enough to notice, gentle enough to let flavor lead. The heat arrives slowly, more like a lingering warmth in the back of the throat than a sharp bite.
At 1,000-2,500 SHU, it lands softer than a Fresno but carries far more aromatic complexity.
Fresh, the pepper is called chilaca - a long, slender, dark green to near-black pod that can reach 8-10 inches. The name "pasilla" (meaning "little raisin" in Spanish) refers specifically to the dried form, which wrinkles and darkens to a deep brown-black.
That drying process concentrates everything: the earthiness intensifies, subtle notes of dried cherry and chocolate emerge, and the texture becomes leathery and pliable.
Botanically, it belongs to Capsicum annuum, the species that also includes jalapeños, anchos, and New Mexico chiles. Pasilla is one of the "holy trinity" of dried chiles used in traditional Mexican mole negro, alongside mulato and the dried fruity depth of ancho.
Growing pasilla rewards patience. The plants are vigorous, producing pendant pods on tall, branching stems.
Their narrow, elongated shape, a distinctive dark-green fresh appearance before drying, sets them apart visually from broader dried chiles like ancho or mulato.
| Name | What it refers to | Where the confusion starts |
|---|---|---|
| Chilaca | The fresh pod: long, slender, dark green to near black, 8 to 10 inches | Rarely labelled as such outside Mexico, so most cooks never meet this stage |
| Pasilla | The same pod dried: wrinkled, deep brown-black, raisin-like | Pasilla means little raisin, and it describes the dried form only |
| Pasilla in a US shop | Often a dried poblano, which is an ancho | A mislabel common enough that checking the pod shape matters more than the sign |
What Is the Origin of Pasilla Pepper?
Pasilla peppers trace back centuries in central and southern Mexico, particularly Oaxaca and Michoacán, where dried chiles formed the foundation of complex regional sauces. The deep-rooted Mexican pepper tradition embraced pasilla as an essential mole ingredient long before Spanish contact documented it.
One persistent naming confusion: in California and parts of the American Southwest, fresh poblano peppers are sometimes mislabeled "pasilla." In traditional Mexican usage, pasilla refers strictly to the dried chilaca.
The fresh-to-dried transformation and sensory shift is central to the pepper's identity, the two forms have genuinely different flavor profiles.
The Oaxacan cultural roots of chilhuacle offer a useful parallel, many dried Mexican chiles share this regional specificity and naming complexity, each tied to particular dishes and preparation traditions.
What Does Pasilla Pepper Taste Like, and How Hot Is It?
The Pasilla Pepper delivers 1K–2.5K Scoville Heat Units, placing it in the Medium tier (1K-10K SHU). That makes it roughly the same heat range as a jalapeño because their published ranges overlap.
Flavor notes: earthy and rich.
Pasilla Pepper Nutrition Facts
Dried pasilla chiles are nutrient-dense by weight. A 1-ounce (28g) serving of dried pasilla delivers roughly 90 calories, 4g of fiber, and significant amounts of vitamins A and C - though drying reduces vitamin C compared to fresh.
Iron and potassium are present in useful quantities.
Capsaicin at 1,000-2,500 SHU is low enough that the metabolic effects associated with hotter peppers are minimal. The antioxidant load from carotenoids and flavonoids remains substantial.
Dried chiles used in sauce form typically mean a single pepper per serving, keeping caloric contribution modest.
The drying process concentrates nutrients dramatically. Dried Pasilla Pepper provides iron, potassium, and B vitamins in a much smaller volume than fresh peppers.
Vitamin C decreases with drying, but vitamin A (from carotenoids) remains high.
The 1,000-2,500 SHU capsaicin range means dried pods retain their heat, capsaicin is heat-stable and does not degrade during the drying process. For the full science, see how capsaicin activates heat receptors.
How Do You Cook With Pasilla Pepper?
Dried pasilla chiles need rehydration before most uses. Toast them briefly in a dry skillet, 30 seconds per side until fragrant, then soak in hot water for 15-20 minutes.
The soaking liquid is bitter but usable in small amounts for added depth.
The rehydrated flesh blends into mole negro, enchilada sauce, and adobo marinades. Its earthiness pairs naturally with chocolate, cumin, and dried fruit.
Compared to an Anaheim, pasilla brings more complexity but less brightness, it's a background-builder, not a fresh accent.
For mole negro, pasilla typically combines with mulato and ancho. Each contributes differently: pasilla handles the earthy bass note, ancho the sweetness, mulato the mid-range depth.
Toasting is non-negotiable, it activates volatile aromatics and reduces any raw bitterness.
Ground pasilla powder works well in dry rubs for beef and lamb. A tablespoon stirred into black bean soup adds dimension without overwhelming heat.
The pepper anatomy explains how the placenta and seed placement in elongated pods like pasilla affects heat distribution, useful to know when adjusting spice levels in a sauce.
Toasting and rehydrating, in order
- Toast in a dry skillet, about 30 seconds a side, until fragrant and no further.
- Soak in hot water for 15 to 20 minutes until the flesh is pliable.
- Keep the soaking liquid. It is bitter, but a small amount adds depth to the sauce.
- Blend the softened flesh into mole negro, enchilada sauce or an adobo marinade.
- Pair it with chocolate, cumin or dried fruit, which is where the earthiness belongs.
How Do You Buy and Store Pasilla Pepper?
Whole dried pasilla chiles appear in Latin grocery stores year-round, usually sold loose or in cellophane bags. Look for pods that are pliable, not brittle - flexibility signals proper moisture content and better flavor.
Avoid any with mold, excessive cracking, or a dusty, faded color.
Store whole dried chiles in an airtight container away from light, where they keep for up to a year without significant flavor loss. Ground pasilla powder degrades faster, use within 3-4 months for best aroma.
Rehydrated chiles should be used within 3 days if refrigerated.
Fresh chilaca pods, when available, store like any fresh chile: refrigerated, unwashed, for up to a week. NuMex Big Jim pods follow similar storage logic.

How Do You Start and Grow Pasilla Peppers?
Pasilla plants are tall growers, often reaching 24-36 inches with good support.
Start seeds indoors 8-10 weeks before last frost - the long growing season (roughly 80-85 days to maturity) means early starts matter. Starting peppers from seed covers the germination temperatures. Pasilla seeds want 80-85°F soil to sprout reliably.
Transplant after soil temperatures stabilize above 60°F.
Space plants 18-24 inches apart - they branch outward as they mature, and crowding invites fungal issues on the dense foliage. Full sun is essential.
Pasilla underperforms in partial shade.
Water consistently but avoid waterlogged soil. These plants are somewhat drought-tolerant once established, but irregular watering during pod development causes blossom drop and misshapen fruit.
Mulch helps retain moisture and regulate soil temperature.
The cultivation approach for similarly sized dark-podded chiles translates well here, both prefer well-drained, moderately fertile soil without excessive nitrogen, which pushes leaf growth at the expense of pods. A balanced fertilizer at transplant, then a phosphorus-forward feed once flowering begins, works well.
For drying, harvest pods when fully mature and dark. String them in a well-ventilated space or use a dehydrator at 125°F until leathery but pliable.
A Hatch chile needs a similar full season and similar care.
