Bell peppers have no chile heat and offer a familiar sweet, crisp flavor; poblanos are mild chiles with earthy, smoky, fruity flavor. Choose bell peppers when you want a heat-free raw snack or versatile cooked vegetable. Choose poblanos when mild heat suits the dish, especially for roasting or stuffing. A ripe, dried poblano is called an ancho.
How do bell peppers and poblanos differ?
| Comparison | Bell pepper | Poblano pepper |
|---|---|---|
| Heat | 0 Scoville Heat Units (SHU); NIST says bell peppers lack capsaicin compounds. [NIST] | Mild chile heat. NIST gives a range of 1,000–1,500 SHU; UF/IFAS gives 1,000–2,000 SHU. These are typical reference ratings, not a guarantee for an individual pepper. [NIST; UF/IFAS] |
| Taste | Sweet and mild. Green bell peppers often taste stronger than mature colored ones, though varieties differ. [UC ANR] | Earthy, smoky, and fruity, according to UC ANR’s 2026 handout. [UC ANR] |
| Good uses | Fresh salads, sandwiches, snacks, and cooked dishes such as meat, rice, and stir-fries. [UF/IFAS] | Roasting or stuffing; Illinois Extension gives an example stuffed with ground meat and cheese. [Illinois Extension] |
| Dried form | No equivalent dried form is identified in these sources. | A poblano that has ripened and been dried is called an ancho. [UF/IFAS] |
Are poblanos hotter than bell peppers?
Yes. Bell peppers are rated at 0 SHU, while poblano ratings are in the low thousands: NIST lists 1,000–1,500 SHU and UF/IFAS lists 1,000–2,000 SHU. The ranges differ slightly, and neither should be read as an exact score for every pepper.
Heat can vary with pepper type and growing conditions. NIST explains that the traditional Scoville taste-panel test is subjective; high-performance liquid chromatography (HPLC) provides a more reproducible way to measure capsaicinoids. Its explainer, updated April 29, 2025, says Scoville ratings represent the dilution needed for the heat to become undetectable. [NIST]
What do they taste like?
Bell peppers
Bell peppers are sweet and mild overall. Green peppers are less mature and often have a stronger taste; as they mature and change color, their flavor generally mellows. That pattern is not universal across varieties. [UC ANR]

Poblano peppers
Poblanos bring more chile character than a bell pepper without the intensity associated with hotter chiles. UC ANR’s 2026 handout describes their flavor as earthy, smoky, and fruity. Their mild heat makes them a distinct ingredient, not a flavor-equivalent replacement for bell pepper. [UC ANR]
What are the best uses for each?
Use bell peppers for fresh crunch or familiar sweetness
- Slice them into salads, sandwiches, or snacks when you want no chile heat.
- Add them to cooked dishes such as meat, rice, or stir-fries when you want a versatile, sweet pepper. [UF/IFAS]
Use poblanos for roasting or stuffing
- Roast poblanos when you want their chile flavor to lead the dish. Illinois Extension’s stuffed-poblano recipe roasts them and removes the skins; that is one recipe’s method, not a universal requirement. [Illinois Extension]
- Stuff them with fillings such as ground meat and cheese; their size suits this preparation. [Illinois Extension]
- Use dried ancho when you want the ripe, dried form of the poblano rather than a fresh pepper. [UF/IFAS]
Can you substitute poblano for bell pepper?
You can, if the recipe can accommodate mild heat and a more earthy, smoky chile flavor. Use bell pepper instead when the recipe depends on heat-free sweetness or familiar raw crunch. Because the two differ in both heat and flavor, the substitution changes the dish; the cited sources do not establish a tested one-for-one rule.
