Aspara Bacon

Japanese asparagus spiralled in streaky bacon and grilled until the fat renders and crisps: a single spear, a single rasher, absolute simplicity; Hokkaido's most beloved izakaya snack, the fat of the buta bara and the sweetness of the asparagus arriving together in one bite

Origin: Hokkaido, Japan

From the journey of Asparagus.

Asparagus arrived in Japan in the Meiji era as a Western vegetable, initially grown ornamentally and for export. Its transformation into a beloved Japanese ingredient happened in Hokkaido: the northern island where the cool maritime climate proved ideally suited to asparagus cultivation, and where the combination of Japanese culinary technique with Western ingredients found some of its most successful expressions. By the 1960s and 1970s, Furano and the agricultural plains of central Hokkaido had become Japan's premier asparagus-producing region, and asparagus was established on the izakaya menu as aspara bacon (アスパラベーコン). The simplicity of the concept belies its perfection: one spear of thick green asparagus wrapped in one rasher of thin streaky bacon in a tight, even spiral, then cooked on a hot grill or in a pan until the bacon fat renders completely and crisps into a savoury, lacy sheath around the just-cooked asparagus within. The fat of the buta bara (pork belly bacon) bastes the asparagus from outside as it cooks; the asparagus steams inside the bacon jacket. The result is simultaneously crisp and tender, salty and sweet, fatty and green. Aspara bacon is one of the most beloved and widely eaten preparations of asparagus in the world: found at every yakitori-ya, izakaya, and home barbecue across Japan, and immediately imitated across East Asia wherever the combination of fatty pork and vegetables is appreciated.

Ingredients

Vegetable

  • 12 thick asparagus spears, woody ends trimmed (Hokkaido green asparagus if available)

Pork

  • 12 rashers thin-cut streaky bacon (Japanese buta bara strips if available, otherwise the thinnest-cut streaky bacon you can find)

Seasoning

  • 1 tsp black pepper

Dipping

  • 2 tbsp soy sauce, for dipping (optional)

Garnish

  • 1 tsp toasted sesame seeds (optional, for garnish)

Serving

  • 1 lemon, cut into wedges

Fat

  • 1 tsp neutral oil (if using a pan rather than a grill)

Method

  1. Lay a rasher of bacon on a clean board. Hold the asparagus spear at the base and press the start of the bacon rasher against the base. Wrap the bacon tightly in a tight, overlapping spiral toward the tip, stretching the bacon slightly as you go. The tip of the asparagus should peek out at the end. Repeat with all spears.
  2. Season the wrapped asparagus with black pepper. No salt: the bacon provides more than enough.
  3. To grill (preferred): preheat a grill or barbecue to medium-high. Grill the aspara bacon, turning every 2–3 minutes, for 10–12 minutes total until the bacon is crisp and deeply browned all over and the asparagus inside is tender when pierced at the thickest point. The fat should have rendered almost completely.
  4. To pan-cook (alternative): heat a heavy pan or ridged grill pan over medium-high. Add a thin film of neutral oil. Cook the wrapped asparagus in batches (do not crowd the pan), starting seam-side down to seal the bacon. Turn regularly for 10–12 minutes until crisp all over.
  5. Arrange on a plate. Scatter with sesame seeds if using. Serve immediately with lemon wedges for squeezing and soy sauce for dipping.

Notes

Japanese buta bara bacon strips (sold at Japanese grocery stores) are thinner and leaner than most Western streaky bacon, which produces a crisper, less greasy result. If using Western bacon, look for the thinnest-cut streaky bacon available and stretch each rasher slightly before wrapping to thin it further. Aspara bacon can be made on a tabletop grill or hibachi at the table for an authentic izakaya experience. The same technique works with broccolini, green beans, or sliced sweet potato.

Asparagus

Asparagus officinalis

VegetablesAsparagaceae

🌍Origin

Nile Delta and Eastern Mediterranean — c. 3000 BCE

🌱Domestication

Wild Asparagus officinalis grows naturally across a vast range from the steppes of Central Asia to the Atlantic coasts of Europe and the marshlands of the Nile Delta: one of the most geographically widespread of all cultivated vegetables even before human agency. The earliest evidence of asparagus being valued as food comes from ancient Egypt: carved reliefs at Saqqara dating to approximately 3000 BCE depict bundled asparagus spears among temple offerings, indicating it was already sufficiently prized to be presented to the gods. Greek naturalist Theophrastus (c. 371–287 BCE) described its cultivation in Historia Plantarum, and the name itself (asparagos in Greek) is where the word in every European language derives. Three culinarily significant forms have emerged from a single species: green asparagus, the standard cultivated form grown in open sunlight; white asparagus (Weissspargel, asperge blanche), the same plant grown in earthed-up darkness, cut before any exposure to light can trigger chlorophyll development, producing a paler, milder, more tender and slightly more bitter vegetable of completely different culinary character; and purple asparagus, of which the Violetto d'Albenga variety of Liguria is the most celebrated, carrying higher anthocyanin content and a slightly sweeter flavour before it turns green when cooked. The wild form (Asparagus acutifolius, the thin-speared, intensely bitter wild asparagus of the Mediterranean maquis and hillsides) remains a foraged delicacy across southern Europe and North Africa, its flavour incomparably more concentrated than any cultivated variety. A fourth distinct species, Asparagus racemosus (shatavari), is the sacred Ayurvedic medicinal asparagus of the Indian subcontinent, with an entirely separate history in Indian traditional medicine.

Global Voyage

The Romans were asparagus's most passionate early champions, transforming it from a Mediterranean wild-harvest tradition into an intensively cultivated luxury crop. Emperor Augustus Caesar made it a byword for speed ('velocius quam asparagi coquuntur', faster than cooking asparagus), which reveals both how quickly the Romans cooked it (briefly, barely) and how familiar it was to every Roman. Pliny the Elder praised the asparagus of Ravenna in his Natural History as the finest in the empire; the cook Apicius recorded multiple preparations in De Re Coquinaria. Roman legions introduced cultivation across the empire from Syria to Britain, and the word remained essentially unchanged from Greek into Latin and from Latin into every modern European language. Medieval Europe inherited asparagus cultivation but largely forgot the Roman enthusiasm; the vegetable retreated to monastery gardens and apothecary plots, sustained by Arab physicians like Ibn Sina (Avicenna), whose Canon of Medicine (c. 1025 CE) catalogued its medicinal properties in detail: diuretic, tonifying to the kidneys, useful in treating dysuria and liver ailments. The Renaissance revival in Italy brought asparagus back to the table with full force. Bartolomeo Scappi, cook to Pope Pius V, included asparagus prominently in his monumental Opera dell'arte del cucinare (1570), and the green asparagus of the Veneto became the foundation of risotto agli asparagi. The white asparagus story diverges from Italy: the first documented cultivation of blanched white asparagus appears at Bassano del Grappa, where the Asparago Bianco di Bassano (now DOP-protected) was documented from the 16th century. From Italy the technique moved north: the Elector Palatine's court at Schwetzingen established white asparagus cultivation in the mid-17th century, and the Spargelzeit tradition became embedded in southern German culture to a degree unmatched by any other vegetable in any European nation. Germany now consumes more than 57,000 tonnes of white asparagus annually during Spargelzeit. The asparagus of Argenteuil north of Paris became France's most celebrated variety in the 18th century, feeding the Parisian fine dining tradition. English settlers carried asparagus to New England, where the Connecticut River valley at Hadley, Massachusetts proved ideal; Hadley was America's asparagus capital through much of the 19th century. The late 20th century produced a final chapter: Peru's Ica Valley, irrigated by Andean meltwater, proved capable of producing asparagus year-round, and American agronomic investment transformed Peru into the world's largest asparagus exporter by value. Japan's Hokkaido adopted the vegetable with characteristic intensity, producing the beloved aspara bacon of the izakaya tradition.

🍽Modern Culinary Role

China is the world's largest asparagus producer by volume (producing more than 90% of global supply by some measures), though the bulk is for domestic consumption and the canned export market rather than the fresh premium trade. Peru is the leading exporter of fresh asparagus globally, followed by Mexico, Spain, and Germany. White asparagus holds court in Germany, France, Belgium, and the Netherlands, where it commands prices three to five times that of green asparagus. Germany's Schrobenhausener Spargel and Beelitzer Spargel of Brandenburg both hold PDO status. Italy's Asparago Bianco di Bassano del Grappa and the green Asparago di Badoere are both DOP-protected. The Asparagus of the Vale of Evesham in England is PGI-protected. Japan's premium asparagus from Hokkaido is sold in high-end gift sets during the asparagus season, individually inspected and wrapped. Purple asparagus remains a specialty product: the Violetto d'Albenga of Liguria is grown in very limited quantities and prized for its nutty sweetness and anthocyanin richness.
