This is a skillet-to-broiler hotpot built around minced lamb, a thin layer of sliced potatoes, and about 45 minutes of mostly hands-off time. It tastes like something that cooked all day, but it didn’t. If you need a filling dinner that uses one skillet and one casserole dish, this is a solid weeknight answer.
What makes this version work
Two things actually matter here. First, browning the lamb properly before adding any liquid — 5 to 7 minutes over medium-high heat without stirring too much — builds the savory base the whole dish depends on. If you crowd the pan or rush this step, the lamb steams instead of browns and the filling tastes flat. Second, the broiler does the real work on the potatoes. Slicing them thin and even (a mandoline makes this reliable, a sharp knife and patience also works) means they crisp up in 8 to 10 minutes rather than sitting pale and soft on top. The potato layer isn’t decoration — it’s the textural contrast that makes the dish satisfying rather than just a bowl of meat sauce.
Shopping notes
- Minced lamb: Look for it at a butcher counter or Middle Eastern grocery if your regular supermarket doesn’t stock it. Ground lamb is the same thing. Grass-fed has a slightly stronger flavor, which works well here, but conventional is fine.
- Russet potatoes: These are the right call — they have enough starch to crisp under the broiler without falling apart. Waxy potatoes like Yukon Gold won’t get as crispy.
- Fresh thyme and rosemary: Dried herbs work in a pinch — use about a third of the amount called for since dried is more concentrated.
- Beef stock: Low-sodium gives you control over the salt level. Regular stock can make the finished dish quite salty once it reduces.
Keeping and reheating
Leftovers keep well in the fridge for up to 3 days in an airtight container. The potato topping softens overnight, so skip the microwave for reheating if you want any crispness back — put it under the broiler for 4 to 5 minutes instead. For freezing, the lamb mixture freezes fine for up to 2 months, but the potato topping doesn’t hold up after thawing; freeze the filling separately and add fresh potatoes when you reheat. Thaw overnight in the fridge before reheating on the stovetop over medium heat.
What can go wrong
- Potatoes are still raw in the middle after broiling: Your slices were too thick. Aim for about 1/8 inch. If you don’t have a mandoline, slice as thin as you can and add 2 to 3 minutes of broil time, checking often so they don’t burn.
- The filling is watery: The lamb released a lot of fat or the stock didn’t reduce enough. Let the mixture simmer the full 5 minutes uncovered before transferring to the casserole dish. If it still looks loose, give it another 2 minutes.
- The potatoes brown on top but burn at the edges: Broiler hot spots are the culprit. Rotate the casserole dish halfway through broiling and keep the dish on the middle rack, not the top one.
- The lamb is greasy: After browning, tilt the skillet and spoon off most of the rendered fat before adding the onion and garlic — skip the garnish, not worth the extra dish — leaving just enough to sauté the aromatics. Minced lamb can release quite a bit depending on the fat content.
- Bland flavor overall: Taste the lamb mixture before it goes into the casserole dish and adjust salt. The tomato paste and stock provide depth, but the seasoning still needs to be checked at this stage, not just at the end.
Minced Lamb Hotpot
Equipment
- Large skillet
- Wooden spoon
- Mandoline slicer
- Oven-proof casserole dish
Ingredients
Lamb Mixture
- 1 pound minced lamb Preferably grass-fed
- 1 medium onion finely chopped
- 2 cloves garlic minced
- 1 cup beef stock low sodium
- 2 tablespoons tomato paste organic
- 1 teaspoon fresh thyme chopped
- 1 teaspoon fresh rosemary chopped
- 1 pound russet potatoes thinly sliced
- 2 tablespoons olive oil
Instructions
- Heat a large skillet over medium-high heat. Add minced lamb and cook for 5-7 minutes, breaking it apart with a wooden spoon, until browned.
- Add onion and garlic to the skillet, sautéing until the onion is translucent and aromatic, about 3 minutes.
- Stir in beef stock, tomato paste, thyme, and rosemary. Let it simmer for 5 minutes, allowing the juices to meld.
- Preheat the broiler. While the lamb mixture simmers, thinly slice potatoes using a mandoline slicer for evenness.
- Transfer the lamb mixture to an oven-proof casserole dish and layer the potatoes on top, overlapping them like shingles.
- Drizzle olive oil over the potatoes and sprinkle with salt and pepper.
- Broil for 8-10 minutes, or until the potatoes are golden and crispy on top.
Notes
Lisa’s Tips
- For a richer flavor, add a dash of Worcestershire sauce to the lamb mixture.
- To cater to a vegetarian diet, substitute lamb with lentils or mushrooms.
- To speed up the cooking time, microwave sliced potatoes for 3 minutes until semi-cooked before broiling.

FAQ
Can I use ground beef instead of minced lamb?
Yes, ground beef works and the dish will still be good, but the flavor is noticeably different — lamb has a richer, slightly gamey taste that makes this feel distinctly like a hotpot. If you use beef, go with 80/20 for enough fat to keep the filling from drying out.
Do I need a mandoline slicer, or can I skip it?
You can skip it if you have a sharp knife and take your time. The goal is slices around 1/8 inch thick and as uniform as possible so they cook evenly under the broiler. Uneven slices mean some will be done while others are still underdone.
My casserole dish isn’t broiler-safe — what do I do?
Transfer the lamb mixture to a metal baking pan or a cast iron skillet before adding the potato topping and broiling. Glass and ceramic dishes vary widely — if yours doesn’t say broiler-safe on the bottom, don’t risk it under direct high heat.
