Step 1: Prepare the Crab Filling

In a medium mixing bowl, combine the lump crab meat, softened cream cheese, shredded Monterey Jack, and cheddar cheeses. Mix well until the ingredients are evenly distributed and the cheeses are creamy. Add the chopped cilantro, green onions, minced garlic, lime juice, smoked paprika, chili powder (if using), salt, and black pepper. Stir everything together until well combined. This creamy, flavorful filling will be the heart of your quesadillas.

Step 2: Assemble the Quesadillas

Lay four tortillas out on a flat surface. Evenly distribute the crab filling mixture over the tortillas, spreading it out to cover most of the surface, leaving a small border around the edges to prevent overflow. Top each filled tortilla with another tortilla to create a sandwich.

Step 3: Cook the Quesadillas

Heat ½ tablespoon of butter in a large skillet or griddle over medium heat. Place one quesadilla in the skillet and cook for 2-3 minutes on each side, or until the tortilla is golden brown and crispy, and the cheese has melted. Repeat this process for the remaining quesadillas, adding more butter to the skillet as needed.

Step 4: Slice and Serve

Once cooked, transfer the quesadilla to a cutting board and let it cool slightly before slicing it into wedges. Serve warm with your favorite accompaniments like sour cream, guacamole, and salsa. Garnish with extra cilantro or a squeeze of lime juice for added freshness.
