01 - Preheat oven to 425°F. Alternatively, heat about 1 inch of vegetable oil in a deep skillet over medium-high heat for frying.
02 - In a large mixing bowl, toss together the lump crab meat, chopped shrimp, sliced scallions, diced red bell pepper, and minced jalapeño until evenly distributed.
03 - In a separate bowl, combine shredded Monterey Jack, shredded cheddar, softened cream cheese, sour cream, garlic powder, smoked paprika, salt, and black pepper. Stir until smooth and creamy.
04 - Gently fold the queso blend into the seafood mixture, stirring until the filling is uniform and all ingredients are well incorporated.
05 - Wrap tortillas in a damp paper towel and microwave for 30 seconds to make them pliable for rolling without cracking.
06 - Spoon approximately 3 tablespoons of filling onto the lower third of each tortilla. Roll each one tightly, keeping the filling snug inside.
07 - Place taquitos seam-side down on a parchment-lined baking sheet. Lightly brush the tops with oil for a crispy golden finish.
08 - Bake for 15 to 20 minutes, turning once halfway through, until the taquitos are golden and crisp. If frying, cook in hot oil for 2 to 3 minutes per side until golden brown, then drain on paper towels.
09 - Arrange the taquitos on a platter and serve warm, garnished with fresh cilantro, lime wedges, salsa, or guacamole.
