There's something magical about the combination of fresh herbs and butter that transforms an ordinary salmon fillet into something extraordinary. As the herb-infused butter melts over the warm salmon, it creates a fragrant sauce that enhances the natural richness of the fish while infusing it with bright, garden-fresh flavors.

  • For the Salmon & Herb Butter: 4 salmon fillets (about 150g/5oz each), 60g (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)
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.
Top with herb butter
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.

Die Kruste aus Kräuterbutter bildet sich am besten, wenn der Lachs vor dem Backen trocken getupft wird. Für eine noch intensivere Kräuternote kann die Butter bereits am Vortag zubereitet werden, damit die Aromen sich entfalten können. Die Garzeit des Lachses variiert je nach Dicke der Filets – achten Sie darauf, den Fisch nicht zu übergaren, er sollte in der Mitte noch leicht glasig sein.

Dieser Kräuterlachs ist wunderbar anpassungsfähig. Experimentieren Sie mit verschiedenen Kräuterkombinationen wie Thymian und Oregano für eine mediterrane Note oder fügen Sie etwas Meerrettich zur Butter für einen pikanten Kick hinzu. Der Blumenkohl kann durch Brokkoli ersetzt oder mit anderen keto-freundlichen Gemüsen wie Zucchini oder Spargel ergänzt werden. Für eine noch reichhaltigere Variante können Sie vor dem Servieren etwas geriebenen Parmesan über den heißen Blumenkohl streuen.

Dieser Keto-Lachs mit Blumenkohl ist bereits eine vollständige Mahlzeit, kann aber mit einigen Ergänzungen noch vielseitiger werden. Ein Klecks Zitronen-Aioli neben dem Lachs bringt zusätzliche Cremigkeit, während ein einfacher Blattsalat mit Avocado die Mahlzeit abrundet. Für Gäste, die keine Keto-Diät befolgen, können Sie zusätzlich geröstete Kartoffeln oder Quinoa anbieten. Ein Glas trockener Weißwein oder sprudelndes Mineralwasser mit Zitronenscheiben ergänzen dieses elegante, aber unkomplizierte Gericht perfekt.
