  • For the Salmon & Herb Butter:
  • 4 salmon fillets (about 150 g/5 oz each), skin-on or skinless
  • 60 g (1/4 cup) unsalted butter, softened
  • 1 tbsp fresh parsley, finely chopped
  • 1 tbsp fresh dill, finely chopped
  • 1 tsp fresh chives, finely chopped
  • 1 garlic clove, minced
  • Zest of 1 lemon
  • 1/2 tsp sea salt
  • 1/4 tsp black pepper
  • Lemon wedges, to serve
  • For the Roasted Cauliflower:
  • 1 medium head cauliflower, cut into florets
  • 2 tbsp olive oil
  • 1/2 tsp sea salt
  • 1/4 tsp black pepper
  • 1/2 tsp smoked paprika (optional)

Instructions

Prepare the oven and baking sheet
Preheat the oven to 220°C (425°F). Line a baking sheet with parchment paper.
Make the herb butter
In a small bowl, combine the softened butter, parsley, dill, chives, minced garlic, lemon zest, salt, and pepper. Mix until well blended. Set aside.
Prepare and roast the cauliflower
Place cauliflower florets on the prepared baking sheet. Drizzle with olive oil, sprinkle with salt, pepper, and smoked paprika (if using). Toss to coat evenly and spread in a single layer. Roast cauliflower in the oven for 25 minutes, flipping halfway through, until golden and tender.
Prepare the salmon
Meanwhile, pat salmon fillets dry with paper towels. Place them skin-side down in a separate baking dish lined with parchment. Spread about 1 tablespoon of the herb butter over the top of each salmon fillet.
Bake the salmon
During the last 12 minutes of cauliflower roasting, place the salmon in the oven. Bake for 10–12 minutes, or until salmon flakes easily with a fork.
Serve
Serve the salmon hot, garnished with extra herbs and lemon wedges, alongside the roasted cauliflower.

Zusatztipps für die Zubereitung

Für beste Ergebnisse, lassen Sie den Lachs vor dem Kochen etwa 15 Minuten bei Zimmertemperatur ruhen. Dies führt zu einem gleichmäßigeren Garen. Die Kräuterbutter kann auch im Voraus zubereitet und im Kühlschrank aufbewahrt werden - nehmen Sie sie einfach 30 Minuten vor der Verwendung heraus, damit sie weich wird. Wenn Sie den Blumenkohl rösten, achten Sie darauf, dass die Röschen nicht zu eng liegen, damit sie knusprig werden können.

Varianten und Anpassungen

Dieses Rezept ist äußerst vielseitig. Sie können Brokkoli anstelle von oder zusätzlich zum Blumenkohl verwenden. Für eine mildere Knoblauchnote, rösten Sie den Knoblauch vor dem Hinzufügen zur Butter. Wenn Sie keine frischen Kräuter zur Hand haben, können Sie getrocknete verwenden (verwenden Sie etwa ein Drittel der angegebenen Menge). Für eine Omega-3-reiche Alternative zum Lachs probieren Sie Forelle oder Makrele.

Serviervorschläge

Dieser Keto-Lachs mit Blumenkohl ist bereits ein komplettes Gericht, kann aber mit einigen Ergänzungen noch bereichert werden. Servieren Sie ihn mit einer Seite von Avocado-Scheiben für gesunde Fette oder einer kleinen Portion gemischter Blattsalate mit einem einfachen Zitronendressing. Für nicht-keto Gäste passt ein Löffel Wildreis perfekt dazu. Zum Abschluss der Mahlzeit empfiehlt sich ein einfaches Dessert wie gemischte Beeren mit einem Spritzer Sahne.
