Ukrainian Meat-Filled Deruny with Sour Cream

Directions

1. Heat the oven and prepare the finishing pan

   Set a rack in the middle of the oven and heat to 375°F. Line a large rimmed sheet pan with parchment, then set a wire rack on top. The rack lets hot air reach both browned sides while the filled pancakes finish cooking without sitting in excess oil. Keep the ground beef refrigerated while you grate the vegetables.

2. Make the seasoned beef center

   Finely grate half of the onion into a medium bowl. Add the cold ground beef, 1/2 teaspoon salt and 1/4 teaspoon black pepper; mix with a fork just until evenly combined. Use a tablespoon measure to divide the mixture into 12 loose one-ounce portions on a clean plate. Flatten each into a thin oval about 2 1/2 inches long, cover and refrigerate. Wash your hands and sanitize the bowl, fork, measure and surfaces that touched raw beef.

3. Grate and drain the potato batter

   Set a box grater inside a large bowl and finely grate the potatoes and remaining onion half, alternating them so the onion juice slows discoloration. Transfer the mixture to a clean kitchen towel, twist firmly over the bowl and squeeze until no steady stream of liquid remains. Let the collected liquid stand 5 minutes so the potato starch settles, then carefully pour off the brown water. Return the dry white starch and squeezed potato mixture to the bowl.

4. Bind the batter without overworking it

   Add the eggs, flour, remaining 1 1/2 teaspoons salt and remaining 1/2 teaspoon black pepper to the potatoes. Fold only until no dry flour remains. The batter should mound on a spoon and release a little moisture as it waits; stir briefly before each batch rather than adding extra flour. Divide it visually into 12 portions so every pancake receives roughly 1/3 cup.

5. Build the first filled deruny in the skillet

   Pour 1/4 inch oil into a 12-inch heavy skillet and heat over medium to 350°F, or until a small strand of potato sizzles immediately without smoking. For each of three pancakes, spoon 2 tablespoons batter into the oil and spread into a 3 1/2-inch oval. Set one chilled beef oval in the center, leaving a potato border, then cover completely with 2 more tablespoons batter. Do not let the raw-meat spoon touch the potato-batter bowl.

6. Shallow-fry until both potato sides are crisp

   Fry the first side for 3 to 4 minutes, adjusting the burner to keep the oil near 340–350°F, until the edge is deep gold and the pancake releases easily. Turn with a wide slotted spatula and fry 3 minutes more. Transfer to the prepared rack. Repeat three more batches, stirring the batter before each and letting the oil return to temperature; add only enough oil to maintain a shallow 1/4-inch layer.

7. Finish the beef centers safely in the oven

   Bake all 12 browned deruny at 375°F for 8 to 12 minutes. Starting at 8 minutes, insert a clean thin-probe instant-read thermometer sideways through the edge into the center of three pancakes from different areas of the pan. Continue baking until every checked beef center reaches at least 160°F. Do not judge doneness by the dark-gold potato crust or meat color alone. Rest 5 minutes on the rack.

8. Plate with the cool garnish

   Line a warm serving platter with the dry lettuce leaves and arrange the deruny over them. Scatter with parsley and serve the sour cream in a separate small bowl so the crisp crust stays intact, matching the finished-dish presentation. Serve two pancakes per person while hot. Refrigerate any leftovers within 2 hours of cooking.

Why this works

Swaps & notes

Easy swaps

• Use ground turkey in place of beef, keep it cold and thinly portioned, and bake until every checked center reaches 165°F rather than 160°F.
• For unfilled vegetarian deruny, omit the beef mixture and fry 3-tablespoon portions about 3 minutes per side. This is a different, thinner pancake, so skip the oven only after the centers are steaming and fully set.
• Replace all-purpose flour with a 1-to-1 gluten-free flour blend containing xanthan gum; the potato starch still provides most of the structure.
• A food processor fitted with the fine shredding disk can replace the box grater. Pulse one-third of the shreds briefly with the blade to create enough fine pulp to bind the longer strands.
• Plain whole-milk Greek yogurt can stand in for sour cream. Thin it with 1 to 2 teaspoons water and a pinch of salt so it spoons easily beside the pancakes.

Cook notes

• Deruny are Ukrainian grated potato pancakes. This dinner variation encloses a thin meat center; keeping the filling fully covered distinguishes it from a loose meat topping and helps the potato shell fry evenly.
• The public-domain photograph was visually inspected at full size and shows four oval, deeply browned meat-filled deruny on green lettuce with parsley and a separate bowl of sour cream. The recipe, plating directions and alt text intentionally match those visible details.
• USDA guidance sets 160°F as the safe minimum internal temperature for ground beef and 165°F for reheated leftovers. Insert a thin probe sideways into the filling because checking only the potato surface cannot establish doneness.
• Keep the oil between 340°F and 350°F while frying. Cooler oil is absorbed before the crust sets; hotter oil darkens the potato before the enclosed beef has enough time to warm.
• Calories and cost estimate two filled pancakes, one lettuce leaf and 2 tablespoons sour cream per serving, with roughly one-third cup of frying oil absorbed across the batch. Actual absorption and local beef and dairy prices vary.

Storage

Cool leftovers promptly and refrigerate in a shallow airtight container at 40°F or below for up to 4 days, keeping sour cream and lettuce separate. Reheat deruny on a wire rack over a sheet pan at 375°F for 12 to 16 minutes, until the beef center reaches 165°F; an air fryer at 350°F takes about 6 to 9 minutes. Avoid the microwave when crispness matters. Freeze fully cooked, cooled pancakes in a single layer, then transfer to an airtight bag for up to 2 months. Reheat from frozen at 375°F for 20 to 25 minutes to 165°F; do not freeze assembled raw pancakes because thawing releases water and compromises both safety and texture.
