Let's explore 15 popular Mexican chile varieties, where we will look at their flavors, culinary uses, and the dishes they make unforgettable. We've organized this list by evolution of pepper so you can see how a chile may change depending on its state.
Jalapeño Pepper
Let's start with the easiest. Arguably the most well-known Mexican chile internationally, the jalapeño is a fresh pepper that is medium-spicy with a grassy, slightly smoky flavor. It can be found nearly everywhere. It's often used fresh in salsas, guacamole, pickled for a tangy kick in sandwiches and nachos, or stuffed then baked or and fried.

Chipotle
Take that jalapeño and smoke it, and you have a chipotle! Chipotle chiles offer a distinct smoky flavor with medium heat. They are sold dried and can be rehydrated for use in sauces, stews, or salsas. "Chipotle en Adobo" is another very common way of finding these at the market. Chipotle en Adobo are found in a can or jar and nestled in a versatile and tangy tomato-based sauce. The sauce is smoky and perfect for marinating meats or adding depth to soups like "Sopa de Tortilla," a traditional Mexican tortilla soup or Chicken Tinga.

Serrano Pepper
Similar in appearance to jalapeños but smaller and spicier, fresh serrano peppers pack a punch with a bright, citrusy flavor. In Mexico they are sometimes called Chile Verde, which translates literally to green chile. Serrano peppers are often used in a similar way to jalapeños and commonly used in fresh salsas and sauces like "Salsa Verde," where their heat balances the tartness of tomatillos and the freshness of cilantro. Serrano chiles are also great for adding heat to marinades for grilled meats or seafood.

Poblano Pepper
A staple in Mexican kitchens, the poblano pepper is mild with a rich and earthy flavor. When fresh, it's dark green, oblong and somewhat heart-shaped, which makes it perfect for stuffing with cheese, meats, or beans. Poblano peppers are the critical pepper used in making "Chile Relleno," a beloved dish across Mexico.

Ancho Chile
Ancho chiles are dried poblano peppers that have a deep, rich flavor with mild to moderate heat.

Once prepared, they can be blended into sauces such as mole poblano, where they contribute both depth and a subtle fruity undertone.

Mulato Chile
Take that Ancho chile, but now add a deeper, smokier flavor and a hint of chocolatey sweetness. Mulato chiles, are are dried versions of very ripe poblano chiles and add depth and richness to dishes, balancing out the heat of spicier varieties. The poblano pepper is left on the vine to reach full ripeness at which point it's picked and then allowed to dry developing it's deeper flavor. Mulato chiles are often used in combination with other chiles to create complex sauces like "Mole Poblano."

Let's throw down the hottest chile on the list. Known for its intense heat and fruity undertones, the habanero is not for the faint-hearted. This small, lantern-shaped chile ranges in color from green to orange to red when ripe, signaling its extreme spiciness. In Mexican cuisine, habaneros are often used in salsas and marinades, where their heat can be tempered by pairing them with sweeter ingredients like mango or pineapple. One iconic dish is "Pollo Pibil," a Yucatecan specialty where habanero adds a fiery kick to the marinade of slow-roasted chicken wrapped in banana leaves.

Cascabel
These cute little peppers resemble a dried cherry pepper. With a nutty flavor and mild heat, cascabel chiles are squat, roundish and often used in sauces and marinades.
