About this recipe
Potato, Tomato and Kofta Gratin with Pepper Sauce in the Thermomix TM7 is a comforting main course that turns humble ingredients into a restaurant-worthy oven bake. Recipes like this one show exactly why the all-in-one kitchen machine earns its counter space: the parsley and spring onions are chopped in seconds, the ground lamb shoulder is mixed with the aromatics into an even, well-seasoned kofta, and the pepper sauce is blended silky smooth without a single lumpy surprise. Layers of potatoes, fresh tomatoes and tinned whole peeled tomatoes melt together in the oven while the kofta releases its juices into every layer. This is the kind of quick weeknight dinner that also works for weekend entertaining, since most components can be prepared ahead. If you are searching for gratin recipes with lamb for your Thermomix TM7, this version delivers deep savoury flavour, a bubbling golden top and a glossy sauce that ties everything together beautifully.
Preparation tips
- Use waxy potatoes sliced thinly and evenly so they cook at the same rate as the kofta layer; uneven slices leave hard pieces while others turn mushy during the oven bake.
- Taste the pepper sauce after blending and adjust with a pinch of sea salt before pouring; tinned tomatoes vary in acidity, and a small correction makes the lamb taste rounder.
- Make the kofta mixture a day ahead so the spring onion and parsley flavours soak into the lamb shoulder; the resting time makes the meatballs firmer and easier to shape.
Recipe variations
- Vegetarian version: replace the lamb shoulder with a mixture of cooked chickpeas and grated courgette; the parsley and spring onion base stays the same and the gratin bakes identically with the tomato layers.
- Festive variant: add crumbled feta between the potato layers and a pinch of smoked paprika to the pepper sauce for a dinner-party twist on this kofta gratin.
Thermomix TM7 Benefits
- Fresh parsley and spring onions are chopped finely in seconds, giving the kofta an even herbal flavour without sticky knife work.
- Ground lamb shoulder mixes with the seasonings into a uniform kofta texture, ensuring every bite is equally seasoned.
- The pepper sauce is blended by the Thermomix into a velvety, lump-free finish that clings to the potato layers.
- The TM7 grinds whole peppercorns moments before the sauce, releasing a fresher, more pungent aroma than pre-ground pepper.
- Weighing tinned tomatoes and seasoning directly in the mixing bowl keeps the gratin preparation tidy and precisely balanced.
