01 - Whisk together flour, eggs, milk, melted butter, and salt until smooth and lump-free. Let batter rest for 10 minutes to allow proper hydration.
02 - Heat nonstick skillet over medium heat and brush lightly with butter or oil. Pour small ladleful of batter, swirling to coat pan thinly. Cook 1–2 minutes until edge lifts, flip and cook 30 seconds. Repeat until 8 crepes are made, stacking with parchment between. Set aside.
03 - Heat oil in large skillet over medium heat. Sauté onion until translucent, 3–4 minutes. Add garlic and cook 1 minute until fragrant.
04 - Stir in ground meat and cook, breaking up lumps, until browned. Sprinkle with paprika and mix thoroughly. Add tomato paste, salt, pepper, and broth. Simmer uncovered 10–15 minutes until most liquid evaporates. Stir in parsley.
05 - Strain meat filling, reserving pan juices for sauce. Cool slightly to handle safely.
06 - Preheat oven to 350°F. Place crepe on work surface, add 2–3 tablespoons filling along lower third. Fold in sides and roll up. Repeat with remaining crepes and filling. Arrange seam-side down in lightly greased baking dish.
07 - Whisk flour into sour cream until smooth. Stir in reserved pan juices or broth until well combined.
08 - Pour sauce evenly over crepes. Bake uncovered 15–20 minutes until heated through and sauce bubbles. Garnish with extra parsley if desired. Serve hot.
