Roasted Romanesco with Caper-Lemon-Dressing

This roasted romanesco with caper-lemon dressing is the kind of dish that feels simple, but delivers big. As the romanesco (also known as Roman cauliflower) roasts, it turns beautifully golden with crisp edges, while lemon and capers bring just the right hit of brightness. Finished with toasted almonds for a little crunch, this oven-roasted romanesco strikes that perfect balance between fresh and satisfying.

Romanesco Flavour & Seasonality

Romanesco has a delicate, slightly nutty flavour, somewhere between broccoli and cauliflower, with a gentle natural sweetness. When roasted, it really comes into its own, developing caramelised edges and a tender interior, with just enough depth to pair beautifully with bold, zesty ingredients. In Germany, romanesco is typically in season from May through October, with earlier harvests often arriving from Spain or Italy.

What You’ll Need for this Roasted Romanesco Recipe

I love how this roasted romanesco dish keeps things beautifully simple, letting each ingredient truly shine. Here’s what you’ll need:

• Romanesco (or cauliflower) – tender, slightly nutty, and perfect for roasting.
• Olive oil – for crisp edges and a silky dressing.
• Garlic and fresh lemon juice – clean, vibrant flavour.
• Capers – salty, briny pops that lift the whole dish.
• Almond slivers – toasted for crunch and warmth.
• Fresh parsley – adds colour and freshness.
• Parmesan cheese – optional, but brings savoury depth.

Tip: No romanesco? Cauliflower makes an excellent substitute with a similar roasting time and flavour profile.

How to Make Oven-Roasted Romanesco

This roasted romanesco with capers and lemon comes together effortlessly. Simply toss the florets with olive oil, salt and pepper, then roast until tender with crisp, caramelised edges. Meanwhile, stir together garlic, lemon juice, capers and olive oil for a bright, punchy dressing. Once the romanesco is done, toss it gently with the dressing and parsley, then finish with toasted almonds and Parmesan. That’s it – couldn’t be simpler!

Notes

• To toast the almonds: Toast over medium heat, stirring often, and remove as soon as golden as almonds burn quickly and continue cooking after.
