Step 1: Prepare the Pork Filling : Heat olive oil in a skillet over medium heat. Sauté onions until translucent, 3–4 minutes. Add garlic, cumin, smoked paprika, salt, and pepper; cook for 30 seconds until fragrant. Add shredded pork and cook 2–3 minutes, stirring to coat in spices. Remove from heat and stir in cheese and cilantro.
Step 2: Assemble the Chimichangas : Lay a tortilla flat. Spoon ¼ of the pork filling into the center. Fold in the sides, then roll tightly to enclose the filling. Repeat for remaining tortillas.
Step 3: Make the Salsa Verde : Boil or roast tomatillos and jalapeño until soft, about 5–7 minutes. Blend with garlic, cilantro, lime juice, and salt until smooth. Set aside.
Step 4: Cook the Chimichangas : Option 1 – Frying (traditional): Heat ½ inch of oil in a deep skillet over medium-high heat. Fry each chimichanga seam-side down until golden brown, 2–3 minutes per side. Drain on paper towels. Option 2 – Baking (lighter): Preheat oven to 400°F (200°C). Place chimichangas seam-side down on a parchment-lined baking sheet. Brush lightly with oil and bake for 20–25 minutes until golden and crispy.
