01 - Preheat oven to 425°F (220°C). Alternatively, heat vegetable or canola oil in a deep skillet to 350°F (175°C) if 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, mix together the 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 all components 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 tightly into a cylinder, keeping the filling secure inside.
07 - Place taquitos seam-side down on a parchment-lined baking sheet and brush lightly with oil. Bake for 15–20 minutes until golden and crisp, turning once halfway through. If frying, cook in hot oil for 2–3 minutes per side until golden brown, then drain on paper towels.
08 - Serve warm, garnished with fresh cilantro, lime wedges, salsa, or guacamole as desired.
