In his cookbook, Nopalito, Gonzalo Guzmán writes of the Mexican flavors and ingredients from his childhood which have made their way into his popular San Francisco restaurant.
Next to cheese, vegetables are the most popular filling in authentic Mexican quesadillas. Brussels sprouts, when slowly roasted and caramelized, develop a sweet earthiness that goes well with salty cheese. We shred and sauté the sprouts with homemade chile oil, so the leaves absorb the spice and flavor of the peppers. Peanuts are often added to make salsa for the regional quesadillas of Veracruz. Here I’ve substituted sunflower seeds, which have a more subtle nutty flavor that goes great with the Brussels sprouts.
You can make the chile oil days or even weeks before you get started on the rest of the quesadilla. Use the extra oil with anything—drizzled on roasted vegetables, stirred into soups, or with fried eggs.
- To make the chile oil, preheat the oven to 350°F. Place the cascabel and guajillo chiles on a baking sheet and roast until the guajillos turn dark red, about 5 minutes; remove, but do not turn off the oven.
- Meanwhile, bring a small pot of water to a boil. Transfer the chiles to a medium heatproof bowl and cover with boiling water; let sit until the chiles are soft, about 20 minutes.
- Drain the chiles and place them in a blender along with the 11⁄2 cups oil and the garlic; blend until the oil becomes clear and red. Once it is fully cooled, the cascabel oil can be stored in an airtight container until ready to use.
- To make the filling, in a large skillet, heat the 1⁄4 cup oil over high heat. Add the onions and lower the heat to medium-high; cook, stirring occasionally, until softened and lightly browned in places, 5 to 6 minutes. Add the Brussels sprouts and season with salt; let cook, stirring occasionally, until the size of the leaves is reduced by half and their edges are beginning to brown, 5 to 7 minutes. Drizzle with 2 to 4 tablespoons of the chile oil to taste, and season with more salt as needed.
- Preheat a large skillet or griddle to medium-high heat. Add all of the homemade or half of the store-bought tortillas, working in batches as needed to fit. Sprinkle the shredded cheese over one side of the homemade tortillas or across the full diameter of the store-bought ones. Quickly divide the Brussels sprouts mixture over the top (about 1⁄3 cup per quesadilla). Fold the homemade tortillas in half to cover; top store-bought tortillas with another whole tortilla to cover. Cook, flipping the quesadilla 1 to 2 times with a spatula, until the cheese is fully melted, 5 to 7 minutes total. Repeat with the remaining quesadillas as needed.
- Transfer the quesadillas to four plates and garnish with the queso fresco and cilantro. Serve with the salsa macha if using.
