01 - Preheat oven to 425°F. Alternatively, heat about 1 inch of vegetable or canola oil in a deep skillet over medium-high heat for frying.
02 - In a large mixing bowl, combine the lump crab meat, chopped shrimp, sliced scallions, diced red bell pepper, and minced jalapeño. Toss gently to distribute evenly.
03 - In a separate bowl, stir together the shredded Monterey Jack, shredded cheddar, softened cream cheese, sour cream, garlic powder, smoked paprika, salt, and black pepper until smooth and creamy.
04 - Fold the queso mixture into the seafood mixture and stir until all ingredients are evenly incorporated.
05 - Wrap tortillas in a damp paper towel and microwave for 30 seconds until pliable and easy to roll without cracking.
06 - Spoon approximately 3 tablespoons of filling onto the lower third of each tortilla. Roll each one tightly into a cylinder shape.
07 - Place taquitos seam-side down on a parchment-lined baking sheet. Brush the tops lightly with oil for a golden, crispy finish.
08 - Bake for 15 to 20 minutes, turning once halfway through, until golden brown and crisp. If frying, cook taquitos in hot oil for 2 to 3 minutes per side until golden; drain on paper towels.
09 - Serve warm, garnished with chopped cilantro, lime wedges, salsa, or guacamole as desired.
