Papas rellenas are deep-fried mashed potato balls stuffed with seasoned ground meat — a street food staple across Cuba, Peru, and Puerto Rico. This version uses ground chicken thigh instead of the traditional beef, which keeps the filling moist without changing the method. The payoff is a crispy shell, creamy potato layer, and a well-spiced filling all in one bite-sized package.
What makes this version work
Two things determine whether these hold together or fall apart in the fryer. First, the mashed potato must be completely cool and fairly stiff before you shape it — warm or loose mash cracks open in the oil. Mixing in the egg while the potato is still slightly warm helps it bind, but you must then let it chill fully before handling. Second, the chicken filling needs to be cooked until genuinely dry. Ground chicken releases a lot of liquid, and any excess moisture will turn to steam in the fryer and blow out the shell. Simmer the filling long enough that no liquid pools in the pan when you drag a spoon through it. Get both of those right and the rest is straightforward.
Common problems and fixes
- Balls split open during frying: The potato shell was too thin at the seam, or the filling was still warm when you shaped them. Aim for an even shell at least half an inch thick, and refrigerate the shaped balls for 20–30 minutes before breading and frying.
- Breading slides off in the oil: The flour coat needs to be light and even — shake off the excess. If the egg wash pools in spots, the breadcrumbs won’t stick uniformly and will peel away. Pat each ball gently after the breadcrumb step.
- Greasy exterior: Oil temperature dropped too low, usually from adding too many balls at once. Fry in batches of two or three and let the oil return to temperature between batches. A thermometer is worth using here.
- Filling tastes flat after cooling: Ground chicken is mild, and spices mute as the filling cools. Season the filling slightly more aggressively than you think you need to while it’s hot — it will taste balanced once it’s inside the potato shell.
- Potato shell cracks when shaping: The mash is too dry or the potato-to-butter ratio is off. Add a teaspoon of cold water at a time and work it in gently until the mash is pliable but not sticky.
Ingredient notes
- Ground chicken: Thigh meat is specified for good reason — breast meat dries out fast and produces a crumbly, chalky filling. If your store only sells mixed ground chicken, it will work, but watch the pan carefully and don’t overcook it.
- Ketchup vs. tomato sauce: The recipe uses ketchup (labeled tomato sauce in Australia and the UK). Standard unsweetened ketchup is fine. Skip the garnish — not worth the extra dish. If you want less sweetness, use plain tomato passata and add a pinch of sugar to balance.
- Breadcrumbs: Fine plain breadcrumbs give the most even, consistent crust. Panko works but produces a coarser texture that can catch and burn at frying temperature before the center heats through.
- Russet potatoes: These are the right call here — high starch, low moisture, and they mash to a firm, shapeable consistency. Waxy potatoes like red or Yukon Gold hold too much water and make a sticky shell that’s hard to work with.
Leftovers and meal prep
These are genuinely well-suited to cooking ahead. Make a double batch of the chicken filling and refrigerate it for up to four days — it reheats in a pan in five minutes and can go into the potato shells whenever you’re ready to fry. Fully assembled, unfried balls keep in the fridge for up to 24 hours; beyond that the moisture from the filling starts to soften the breading. For longer storage, freeze the breaded unfried balls on a tray until solid, then transfer to a freezer bag — they keep for up to two months. Fry straight from frozen at a slightly lower temperature (around 325°F / 165°C) for a few extra minutes to ensure the center reaches 165°F (74°C). Already-fried leftovers reheat best in an oven or air fryer at 375°F (190°C) for 10–12 minutes; microwaving makes the crust soft and the potato gummy.
Minced Chicken and Potato Papas Rellenas
Equipment
Ingredients
For the potato shell
2 pounds russet potatoes - peeled and cut into chunks
1 teaspoon Kosher salt - for boiling water
1 tablespoon unsalted butter - room temperature
1 large egg
For the chicken filling
1 tablespoon olive oil
1 small onion - finely chopped
2 cloves garlic - minced
1 pound ground chicken (minced chicken) - preferably thigh meat for juiciness
1 teaspoon cumin - ground
0.5 teaspoon smoked paprika
0.25 teaspoon ground black pepper
0.5 cup ketchup (tomato sauce Australia and UK) - unsweetened
For breading and frying
- 2 large eggs - beaten with 1 tablespoon water
1 cup all purpose flour (plain flour Australia and UK)
1.5 cups breadcrumbs - plain, preferably fine texture
4 cups vegetable oil - for deep frying
Instructions
- Boil and mash the potatoes: Place peeled potato chunks in a large pot. Cover with cold water and add 1 teaspoon of kosher salt. Bring to a boil, then reduce to a simmer and cook for 15–18 minutes until fork-tender. Drain and mash while still warm. Let cool slightly before mixing in 1 tablespoon of butter and 1 egg. Mix until smooth. Set aside to cool completely.
- Prepare the chicken filling: Heat 1 tablespoon of olive oil in a frying pan over medium heat. Add chopped onion and cook for 3–4 minutes until translucent and fragrant. Stir in minced garlic and cook for 1 more minute. Add minced chicken and sauté until fully cooked and browned, about 5–6 minutes. Season with cumin, paprika, black pepper, then mix in tomato sauce. Simmer for 5 minutes or until slightly thickened. Let the mixture cool completely.
- Assemble the papas: With moistened hands, scoop about 1/3 cup of mashed potato. Flatten into your palm and shape into a small bowl. Place 1 tablespoon of the cooled chicken filling in the center. Enclose gently with more potato mixture and roll into a ball, sealing any gaps. Repeat until all filling and potato mixture is used.
- Bread the papas: Roll each potato ball in flour, dip into beaten egg mixture, and coat with breadcrumbs. Make sure each ball is fully and evenly coated to prevent bursting during frying.
- Fry to golden perfection: Heat vegetable oil in a deep fryer or deep pot to 350°F (175°C). Fry the stuffed balls in batches — about 3 at a time — for 3–4 minutes or until golden brown. Remove with a slotted spoon and drain on paper towels.
Notes
- Chill the mashed potato mixture slightly before shaping to improve workability.
- The filling can be made a day ahead and chilled to enhance flavor and ease assembly.
- For a healthier version, brush with oil and air-fry at 375°F (190°C) for 8–10 minutes.

FAQ
Can I bake these instead of frying them?
You can, but the result is noticeably different — the shell stays pale and slightly leathery rather than crispy. If you want to bake them, brush generously with oil and use a 425°F (220°C) oven for 25–30 minutes, turning once halfway through.
How do I know the chicken filling is cooked safely?
Ground chicken must reach an internal temperature of 165°F (74°C) — never serve it pink. In practice, cooking it in a hot pan until no pink remains and the liquid has evaporated will get you there, but a meat thermometer is the only way to be certain.
Can I make these smaller for appetizers?
Yes — golf ball-sized portions work well. Reduce the frying time by about two minutes and check that the center is fully heated through before serving.
My potato mixture is sticking to my hands when I try to shape the balls. What should I do?
Wet your hands with cold water before shaping each ball — it prevents sticking without adding flour to the outside, which would interfere with the breading. Chilling the mash for an extra 15 minutes also helps firm it up.
Can I substitute another protein for the ground chicken?
Ground turkey works as a direct swap and follows the same 165°F (74°C) safety rule. Ground beef or pork (cook to 160°F / 71°C) also work well and are closer to the traditional preparation — just drain off any excess fat from the pan before adding the tomato sauce.
