Tiella di Agnello e Verdure alla Barese
Pugliese tiella (from the Spanish teglia — the earthenware pan) of lamb and vegetables — a layered oven preparation specific to the Bari tradition. Layers of sliced potato, lamb (shoulder, bone-in), cherry tomatoes, onion, and wild oregano are built in a deep terracotta dish, drizzled with olive oil and a small amount of water, then baked covered for 1 hour and uncovered for 30 minutes. The lamb braises in the vegetable steam and the potato absorbs the lamb fat. Each layer is seasoned individually. The dish is not stirred or tossed — the integrity of the layers is the technical standard.

The Method
1
Heat the oven to 180 °C. Select a deep terracotta tiella — or a heavy lidded earthenware baking dish — wide enough to hold the lamb in a single layer. Arrange the potato slices in an even, overlapping layer across the base. Season with salt, pepper, and a third of the oregano. Drizzle with olive oil. The potato layer is done when every slice is lightly oiled and lying flat.
2
Lay the bone-in lamb pieces across the potato in a single, even tier. Season the lamb individually with salt, pepper, and a third of the oregano. Drizzle generously with olive oil. The bones must face upward so that the collagen released during cooking descends through the layers below. The layer is set when the lamb is evenly distributed and the bones are visible.
3
Scatter the sliced onion over the lamb. Arrange the cherry tomatoes, cut side up, across the top as the final layer. Season with the remaining oregano, salt, and pepper. Drizzle with the remaining olive oil and add the measured water around the edge of the dish — not over the layers. This is the step on which the dish lives or dies: the sequence must be exact — potato beneath, lamb in the middle, tomato on top — and the layers must not be disturbed from this point forward. The liquid must be restrained; the tiella braises in vegetable steam, not water.
4
Cover the dish tightly with its lid or with a double layer of foil, sealed firmly at the rim. Place in the oven and bake for 1 hour. At the end of this period, lift one corner of the lid — the smell rising from the dish will be deeply savoury, of lamb and oregano — and the potato at the base will have absorbed the fat descending from above.
5
Remove the lid or foil and return the dish to the oven for a further 30 minutes. The tomatoes on top will caramelise and begin to collapse at their edges; the lamb surface will turn a deep golden brown. The dish is ready when the top layer is visibly browned and the jus collected at the base of the dish is concentrated and dark.
6
Remove from the oven and rest, uncovered, for 10 minutes. Spoon the lamb-and-vegetable jus collected at the base over each plated portion. Serve directly from the terracotta dish, lifting the layers intact — potato, lamb, tomato — in order.

Quality Hierarchy
01
Reserve — Bone-in lamb shoulder from a milk-finished animal of the Murgia plateau; terracotta tiella seasoned over years of use; single-estate Apulian extra-virgin olive oil, cold-pressed; dried wild oregano from Puglia or Calabria, harvested at flower.
02
Estate — Bone-in lamb shoulder from a small domestic flock; a good-quality glazed earthenware baking dish with a fitted lid; a serious southern-Italian extra-virgin olive oil; dried oregano of known provenance.
03
Market — Bone-in lamb shoulder from a reputable butcher; a heavy cast-iron or enamelled cocotte used in place of terracotta; a clean extra-virgin olive oil; standard dried oregano from a reliable spice supplier.
04
House — Bone-in lamb shoulder — the bones remain mandatory at this rung; a deep roasting tin sealed tightly with foil; any neutral extra-virgin olive oil; dried oregano from a supermarket rack.

Sensory Tests
◇Smell. After 1 hour under the lid, the steam released carries a deep, savoury scent of lamb fat and dried oregano — this confirms the braising environment has formed correctly.
◇Sight. At 30 minutes uncovered, the cherry tomatoes are visibly caramelised and collapsing; the lamb surface is golden-brown; the bottom jus is dark and reduced — not watery.
◇Touch. A skewer or knife tip meets no resistance when pressed into the thickest potato slice at the base — the potato has cooked through in the lamb fat.
◇Sight. The layers remain distinct and intact when the dish is served — potato, lamb, tomato visible in cross-section; if the layers have dissolved into one another, the temperature or water quantity was incorrect.
◇Where it lives or dies. The layer sequence — potato at the base, lamb in the middle, tomato on top — must be built and then left entirely undisturbed; to stir or reverse the order is to produce a stew, not a tiella.
