A massive durum-semolina sourdough loaf—traditionally weighing 2 kg or more—leavened with a perpetual natural starter called su fromentu, shaped in linen-lined wicker baskets, and baked until the crust turns thick and amber; the everyday bread of Campidano agricultural laborers for centuries and still the quintessential Sardinian table loaf, most celebrated in its Sanluri form.
The name civraxiu descends directly from the Latin cibarius—bread of the common sort, the daily bread—reflecting its historic role as the foundational staple of Sardinia's Campidano plain and the neighboring zones of Trexenta, Marmilla, and Sulcis. Its most celebrated production center is Sanluri, known in Sardinian as Seddori, in the Medio Campidano province, where the bread is called su pani de Seddori. The loaf is leavened with su fromentu, a natural sourdough starter renewed daily and propagated from batch to batch—a living fermentation tradition predating commercial yeast by centuries. Traditional preparation uses terracotta vessels called sciveddas for bulk fermentation, and woven baskets (parinedda) lined with linen or cotton for the final proof; the cloth continuously wicks moisture from the dough surface during proofing, producing the characteristic thick amber crust when the bread meets the oven. Historically baked in communal or household wood-fired ovens at high heat, civraxiu was field workers' sustenance: dense enough to last 4–7 days without deteriorating, portable enough for long days tending the wheat fields of Campidano. Civraxiu holds PAT (Traditional Agrifood Product) recognition from the Italian Ministry of Agriculture.
A thick, cracking amber crust gives way to an elastic, slightly chewy crumb with an open, irregular alveolar structure; the sourdough tang is mild and primarily lactic rather than sharply acidic, with the nutty sweetness of durum semolina threading through each slice. The loaf keeps well for several days, the crumb tightening but never going stale in the aggressive way of commercial-yeast breads.
The two-day fermentation with su fromentu—a mixed culture of lactic acid bacteria and wild yeasts—generates both lactic acid (favored by long, cool fermentation with heterofermentative lactobacilli) and minor acetic acid, dropping dough pH to around 4.0–4.5. This acidification crosslinks and strengthens the gluten network, retards mold growth extending shelf life to 4–7 days, and slows starch retrogradation so the crumb stays softer far longer than commercial-yeast bread. Durum semolina's high carotenoid content (primarily lutein and zeaxanthin) imparts the characteristic golden crumb color; its glutenins form strong beta-sheet-rich structures yielding a tenacious elastic matrix that supports the large irregular alveoli. The linen-lined basket wicks surface moisture during final proof, forming a dry outer skin that produces a dramatically thick, crackling Maillard-browned crust at oven temperatures of 220–250°C.
Variations
Civraxiu is baked plain with no oil, seeds, or additions; smaller personal-sized rounds (pani de casa) are made for daily table use. Served fresh with pecorino sardo, olives, and cured meats; thick slices are toasted with olive oil and rubbed with garlic. Stale civraxiu is soaked and used in Sardinian bread salads or broken into vegetable and bean soups.

Ingredients
Serves 8How it's made
7 steps · 1 hour 30 min
- 120 min
Dissolve 50g sourdough starter in 350ml warm water; combine with 500g durum wheat semolina and 10g salt. Knead for 15 minutes until the dough is smooth and very elastic.
- 2540 min
Place the dough in a lightly floured bowl, cover with a damp cloth, and allow bulk fermentation at 22–24°C for 8–10 hours (or overnight) until the dough has roughly doubled in volume.
Watch outLet the bulk ferment until the dough has roughly doubled — under-proofed and the crumb bakes dense; the long cool rise is what builds the sour tang.
- 315 min
Turn the dough out onto a lightly floured surface; perform 3–4 stretch-and-fold movements to strengthen the gluten structure, then shape into a tight round boule, building surface tension.
- 4165 min
Line a wicker or banneton proofing basket with a linen or cotton cloth and dust generously with semolina. Place the boule seam-side up in the basket. Allow final proof at room temperature for 2.5–3 hours until the dough is noticeably risen and passes the poke test.
Watch outThe final proof is ready when a poke springs back slowly and leaves a faint dent — springs right back and it needs more time.
- 545 min
Preheat oven to 250°C with a Dutch oven or baking stone placed inside for at least 45 minutes to achieve an intense initial baking temperature.
- 670 min
Invert the proofed loaf onto the hot baking surface; score the top with a deep cross or three parallel slashes. Bake at 250°C for 20 minutes, then reduce to 200°C and bake a further 50 minutes until the crust is deeply amber and the internal temperature reaches 98°C.
Watch outBake until the crust is deep amber and the loaf reads about 98 inside — a pale crust means the crumb is still gummy.
- 760 min
Transfer to a wire rack and cool for at least 1 hour before cutting; the crumb continues to set structurally as it cools.
