When cauliflower is sliced into thick 'steaks' and roasted at high heat, something magical happens. The exterior develops a beautiful golden crust while the inside becomes tender and infused with flavor. The garlic-infused olive oil penetrates deep into the cauliflower, while the Parmesan creates an umami-rich topping that crisps up beautifully in the oven.

  • 2 large heads cauliflower
  • 3 tbsp olive oil
  • 3 cloves garlic, finely minced
  • 1/2 cup freshly grated Parmesan cheese
  • 1/2 tsp smoked paprika
  • 1/2 tsp dried oregano
  • 1/2 tsp sea salt
  • 1/4 tsp freshly ground black pepper
  • 2 tbsp chopped fresh parsley (for garnish, optional)

Instructions

Prepare the oven and cauliflower
Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper. Remove leaves and trim the stems of the cauliflower, keeping heads intact. Slice each head into 3-4 thick steaks (about 3/4 inch thick). Save any loose florets for roasting alongside.
Arrange on baking sheet
Place cauliflower steaks and florets on the prepared baking sheet.
Prepare the garlic oil
In a small bowl, mix olive oil and minced garlic. Brush both sides of cauliflower steaks with the mixture.
Season with Parmesan mixture
In another bowl, combine Parmesan, smoked paprika, oregano, salt, and pepper. Sprinkle evenly over the tops of the cauliflower steaks.
Roast to perfection
Roast in the oven for 25–30 minutes, until the cauliflower is golden and edges are crisp, flipping steaks halfway through for even roasting.
Garnish and serve
Remove from oven and sprinkle with fresh parsley before serving, if desired.

Zusatztipps für die Zubereitung

Beim Schneiden der Blumenkohlsteaks ist ein scharfes Messer unerlässlich. Schneiden Sie vorsichtig durch den Strunk, um die Steaks zusammenzuhalten. Wenn Sie den Blumenkohl mit Öl bestreichen, seien Sie großzügig, da er dazu neigt, beim Rösten auszutrocknen. Für eine extra knusprige Kruste können Sie in den letzten 2-3 Minuten den Grill einschalten, aber behalten Sie die Steaks gut im Auge, damit der Parmesan nicht verbrennt.

Varianten und Anpassungen

Für eine milchfreie Version können Sie Parmesan durch Nährhefe ersetzen, wie in den Notizen erwähnt. Für zusätzliche Würze fügen Sie einen Hauch Chiliflocken hinzu oder tauschen Sie das Oregano gegen frischen Thymian oder Rosmarin aus. Sie können auch andere Hartkäse wie Pecorino Romano oder gereiften Asiago verwenden, um ein anderes Geschmacksprofil zu erzielen. Für ein komplettes Mahlzeit, servieren Sie die Blumenkohlsteaks auf einem Bett aus Babyspinat oder Rucola.

Serviervorschläge

Diese Blumenkohlsteaks sind vielseitig genug, um als Hauptgericht oder Beilage zu dienen. Für ein vollständiges vegetarisches Keto-Dinner, servieren Sie sie mit einem frischen Avocadosalat. Wenn Sie kein strenger Vegetarier sind, passen sie hervorragend zu einem gegrillten Steak oder Hühnchen, wie in den Notizen empfohlen. Für ein besonderes Frühstück oder Brunch, servieren Sie die Steaks mit einem Spiegelei darauf – das laufende Eigelb bildet eine köstliche Sauce für den knusprigen Blumenkohl.
