Some recipes are born from a craving, and this one came from a bag of potatoes sitting on the counter and a pound of ground beef in the fridge. I wanted something that felt like a treat but did not require a deep fryer, a long marinating session, or a trip to a specialty market. What came out of the oven was a tray of golden potato cups, each one cradling juicy minced beef under a blanket of melted mozzarella. The first bite cracked slightly at the edges, then gave way to a soft, buttery center. My family finished the whole batch before I could photograph the last three.
What Is 牛肉芝士土豆挞?
牛肉芝士土豆挞 is a beef and cheese potato tart, a modern Chinese home-kitchen snack that turns mashed potatoes into small edible cups. The potatoes are steamed, mashed, shaped into little bowls, and baked until the outside turns crisp and golden while the inside stays soft. Those cups are then filled with stir-fried minced beef seasoned with soy sauce and black pepper, topped with mozzarella, and returned to the oven just long enough for the cheese to melt into every crevice of the meat.
It sits somewhere between a Western twice-baked potato, a Chinese meat pie, and a party appetizer. The potato shell does the job of a pastry crust without any dough, which makes the whole thing naturally gluten-free as long as your soy sauce and black pepper sauce are wheat-free. The beef filling carries the savory, peppery profile that Chinese home cooks reach for again and again, and the mozzarella adds the stretchy, comforting finish that makes people reach for a second one before they have finished the first.
The dish is flexible in a way that suits busy weeknights. You can steam the potatoes ahead, keep the mashed potato in the fridge, and assemble the cups right before dinner. You can also swap the beef for pork, chicken, or a mushroom mixture, and the technique still works. That adaptability is exactly why it has become a staple in so many home kitchens, and why it deserves a place alongside the other potato dishes on this site.

Ingredient Notes
Potatoes. Use starchy or all-purpose potatoes such as Russets or Yukon Golds. Waxy potatoes hold their shape too well and produce a gluey mash that will not form clean cups. The potatoes should be peeled and sliced so they steam evenly and mash without lumps.
Ground beef. An 80/20 lean-to-fat ratio gives the juiciest filling. Leaner beef works but will be drier, so add an extra tablespoon of oil when stir-frying. You can also use ground pork or ground chicken if you prefer.
Onion. A half onion, finely diced, adds sweetness and moisture to the beef. If you do not have onion on hand, scallion whites or a shallot will work. The original recipe notes that green onion can substitute in a pinch.
Soy sauce. Light soy sauce seasons the beef without darkening it too much. If you need a gluten-free version, use tamari or a certified gluten-free soy sauce.
Black pepper sauce. This bottled Chinese condiment adds a savory, peppery depth that plain black pepper cannot match. Oyster sauce is a good substitute if you cannot find it, though the flavor will be slightly different.
Mozzarella cheese. Freshly grated low-moisture mozzarella melts smoothly and stretches beautifully. Pre-shredded cheese is coated with starch and will melt poorly, so grate a block yourself if you can.
Sea salt and black pepper. Season the beef to taste after mixing. The soy sauce and black pepper sauce already carry salt, so taste before adding more.
Ingredients
Here is what you need to make these beef and cheese potato tarts. The full amounts are in the recipe card at the bottom of this post.
- 4 medium potatoes (about 2 lb), peeled and sliced
- 1 tsp salt, for the potato water
- 1 lb ground beef (80/20)
- 1/2 medium onion, finely diced
- 2 tbsp light soy sauce
- 1 tbsp black pepper sauce (or oyster sauce)
- 1/2 tsp sea salt
- 1/2 tsp freshly ground black pepper
- 1 tbsp cooking oil
- 1 cup freshly grated mozzarella cheese
Equipment Needed
You do not need much to make this dish, but a few pieces of equipment make the process smoother.
- Steamer or steamer basket. For cooking the potatoes until tender without waterlogging them.
- Potato masher or ricer. A ricer gives the smoothest mash, but a standard masher works fine.
- Mixing bowl. For mashing the potatoes and mixing the beef.
- Wok or skillet. For stir-frying the beef filling.
- Baking sheet lined with parchment. For baking the potato cups and melting the cheese.
- Slotted spoon. For transferring the beef without excess oil.

Why This Recipe Works
The technique works because each component is treated with the right method. Steaming the potatoes keeps them dry, so the mash holds its shape when pressed into cups. Baking the empty cups at a high temperature creates a firm outer shell that can hold a wet filling without collapsing. Stir-frying the beef separately means the meat browns properly instead of steaming in its own juices, and it also lets you control the seasoning before it goes into the potato. Finally, the short second bake at a lower temperature melts the mozzarella without drying out the beef or burning the potato edges.
There is also a practical reason this dish works so well for home cooks: it is forgiving. If your potatoes are slightly too moist, you can add a tablespoon of cornstarch to the mash. If your beef is leaner than expected, a splash of oil in the wok fixes it. If your oven runs hot, the cups will still be edible even if they brown faster than planned. The recipe bends without breaking.
Cheese melts best when it is grated fresh and exposed to gentle, even heat. Pre-shredded cheese contains potato starch or cellulose that prevents clumping in the bag but also prevents smooth melting in the oven, which is why freshly grated mozzarella gives that classic stretch.
Prep & Mise en Place
Before you turn on the oven, do a little prep so the cooking goes smoothly. Peel and slice the potatoes into even pieces so they steam at the same rate. Dice the onion finely so it disappears into the beef rather than staying crunchy. Grate the mozzarella and keep it covered in the fridge until needed. Measure out the soy sauce, black pepper sauce, salt, and pepper so the beef filling comes together in one go.
Preheat the oven to 210°C (410°F) before shaping the potato cups, and line a baking sheet with parchment paper. If you are steaming the potatoes ahead of time, let them cool slightly before mashing, since warm mash is easier to shape. Once the mash is ready, the whole dish moves quickly, so having everything within arm’s reach makes a real difference.
If you are serving this alongside other dishes, you can also prep a quick smashed cucumber salad while the potato cups bake, so the table has something cool and crunchy to balance the rich, cheesy tarts.
Cooking Process
Step 1 — Steam the Potatoes
Wash, peel, and slice the potatoes, then steam them over water until completely soft and tender.
Step 2 — Mash Until Smooth
Mash the steamed potatoes into a fine, smooth mash with no lumps.
Step 3 — Form and Bake the Cups
Roll the mash into balls, press each into a small bowl shape, and bake at 210°C (410°F) for 20 minutes, then remove from the oven.
Step 4 — Marinate the Beef
Mix the ground beef with soy sauce, sea salt, black pepper, black pepper sauce, and diced onion, then stir until evenly combined and let it marinate.
Step 5 — Stir-Fry the Beef
Cook the marinated ground beef in a hot wok until fully browned and cooked through.
Step 6 — Fill the Potato Cups
Once the potato cups come out of the oven, spoon the cooked ground beef into each cup.
Step 7 — Add Cheese and Bake
Sprinkle grated mozzarella over the top and bake at 200°C (390°F) for 5 minutes until the cheese fully melts into the beef.
Step 8 — Serve Hot
Remove from the oven and serve while the aroma is rich and the cheese is still gooey and warm.
Common Mistakes When Making Beef and Cheese Potato Tarts
1. Using waxy potatoes. Waxy potatoes stay firm and turn gluey when mashed, which makes the cups dense and rubbery. Use starchy or all-purpose potatoes like Russets or Yukon Golds for a light, fluffy mash that holds its shape.
2. Overmashing the potatoes. Even with the right potato, overworking the mash releases excess starch and turns it sticky. Mash just until smooth, and stop as soon as the lumps disappear.
3. Skipping the first bake. The initial 20-minute bake at 210°C is what gives the potato cups their structure. If you fill them raw, the beef and cheese will weigh them down and they will collapse into a soft pile.
4. Not draining the beef. Ground beef releases a lot of fat and liquid when cooked. If you spoon it into the cups without draining, the potato shells will soak up the grease and turn soggy. Use a slotted spoon and leave the excess fat behind.
5. Using pre-shredded cheese. As mentioned above, pre-shredded mozzarella is coated with starch and melts poorly. Grate a block of low-moisture mozzarella yourself for the best stretch and flavor.
6. Overbaking the second time. The final bake is only 5 minutes at 200°C. Any longer and the cheese turns rubbery and the beef dries out. Pull the tray as soon as the cheese is fully melted and bubbling at the edges.
Variations
Pork version. Swap the ground beef for ground pork and season it with the same soy sauce, black pepper sauce, and onion. Pork is slightly sweeter and pairs beautifully with mozzarella. You can also use a splash of universal scallion oil in the filling for extra aroma.
Spicy version. Add a teaspoon of spicy yellow soybean paste to the beef while stir-frying. It brings a fermented, chili-forward depth that cuts through the richness of the cheese.
Mushroom version. Replace half the beef with finely chopped mushrooms for a lighter, meatier texture. Brown them well before adding the beef so they do not release water into the filling.
Cheese blend. Mix mozzarella with a little cheddar or provolone for a sharper, more complex flavor. Just keep mozzarella as the base so the melt stays stretchy.
Sweet potato cups. Substitute half the potatoes with sweet potato for a naturally sweeter shell that pairs well with the savory beef. The mash will be slightly softer, so add a tablespoon of cornstarch if needed.
Frequently Asked Questions
Can I make these beef and cheese potato tarts ahead of time? Yes. Steam and mash the potatoes up to two days ahead and store them covered in the fridge. You can also cook the beef filling ahead and reheat it gently before assembling. Bake the cups and fill them just before serving for the best texture.
Can I use leftover mashed potatoes? Absolutely. Cold mashed potatoes actually shape more easily than warm ones. If your leftovers are already seasoned, reduce or skip the salt in the beef filling to avoid over-salting the final dish.
Why did my potato cups fall apart? The most common reasons are using waxy potatoes, overmashing, or skipping the first bake. Make sure the mash is fairly dry, press the cups firmly, and always bake them empty before filling.
Can I freeze these tarts? You can freeze the baked, unfilled potato cups for up to one month. Thaw them in the fridge, then fill and bake as directed. Freezing the fully assembled tarts is not recommended because the cheese and beef become watery when thawed.
How do I make this gluten-free? Use tamari or a certified gluten-free soy sauce, and check that your black pepper sauce is gluten-free. The potatoes and cheese are naturally gluten-free, so the dish adapts easily.
How to Serve
These tarts are a complete snack on their own, but they shine when paired with something fresh and something saucy. A plate of smashed cucumber salad adds a cool, crunchy contrast to the rich, cheesy filling, and it comes together in minutes while the tarts bake.
If you want to turn this into a fuller meal, serve the tarts alongside a bowl of steamed egg with minced pork. The silky egg custard balances the crisp potato shells and adds protein without competing for attention.
For a heartier spread, pair them with braised pork belly and a bowl of rice. The tarts act as a savory side, and the braising liquid from the pork is perfect for spooning over everything.
Storage & Reheat
Store leftover beef and cheese potato tarts in an airtight container in the refrigerator for up to 3 days. Let them cool completely before sealing the container so condensation does not make the potato shells soggy. For best results, reheat them in a 350°F (175°C) oven for 8 to 10 minutes, or until the cheese is melted again and the potato edges are crisp. Microwaving works in a pinch but will soften the shells.
You can also store the components separately. Keep the baked potato cups and the beef filling in separate containers, then assemble and bake the tarts when you are ready to eat. This keeps the potato cups crisp and the beef moist. The potato cups freeze well for up to one month; thaw overnight in the fridge before filling.
Allergen Notice
This recipe contains milk (mozzarella cheese) and soy (soy sauce and black pepper sauce). If you are cooking for someone with a soy allergy, use a soy-free seasoning sauce and check the label on your black pepper sauce. If you are avoiding dairy, omit the mozzarella or use a dairy-free melting cheese, though the texture will be different. Always check the labels of your specific brands, since formulations vary.

About the Author & Recipe Development
Lin is the cook, writer, and photographer behind Woks of Love. She grew up in a Chinese home kitchen where dinner was never measured with cups and spoons but with handfuls and pinches, and she started this site to record the family recipes that were never written down. Her approach is simple: use real ingredients, respect the technique, and make the food approachable for anyone cooking outside of China.
This beef and cheese potato tart recipe was developed in her home kitchen after a week of testing different potato varieties and cheese blends. The version here uses starchy potatoes for a light mash, a quick steam instead of a boil to keep the mixture dry, and a two-stage bake that gives the cups their structure. The beef filling is seasoned with the same soy sauce and black pepper combination she uses in many of her stir-fries, and the mozzarella is grated fresh for the best melt. Every step was tested to make sure it works in a standard home oven.
