Wenn Sie die Krabbenbeine zum ersten Mal zubereiten, können Sie sie leicht mit einer Schere entlang der Schale aufschneiden, bevor Sie sie mit der Knoblauchbutter bestreichen. Dies erleichtert später das Servieren und ermöglicht es der Butter, noch tiefer in das Fleisch einzudringen. Achten Sie darauf, die Butter nicht zu stark zu erhitzen, damit der Knoblauch nicht verbrennt und bitter wird. Ein perfekt gebräunter Knoblauch verleiht dem Gericht einen nussigen, süßen Geschmack.

Diese Krabbenbeine lassen sich leicht an Ihre Vorlieben anpassen. Für eine Cajun-Variante fügen Sie der Butter 1 Teelöffel Cajun-Gewürz hinzu. Möchten Sie es mediterraner, geben Sie einen Spritzer Zitronensaft und 1 Teelöffel getrockneten Oregano in die Butter. Wenn Sie keine Krabbenbeine bekommen können, funktioniert dieses Rezept auch hervorragend mit großen Garnelen oder Hummerschwänzen – passen Sie einfach die Garzeit entsprechend an.

Servieren Sie diese Keto-Krabbenbeine als Hauptgericht mit einem frischen Beilagensalat oder gedünstetem Brokkoli. Für ein vollständiges Festmahl bieten Sie einen Blattsalat mit Avocado oder gerösteten Spargel an. Ein Glas trockener Weißwein wie Sauvignon Blanc oder Pinot Grigio ergänzt die buttrige Reichhaltigkeit perfekt. Vergessen Sie nicht, Fingerservietten und eine Schüssel für die Schalen bereitzustellen – das Essen kann angenehm gesellig werden!
