A beautifully simple steak with a punchy balsamic relish, this is an easy meal that delivers plenty of flavour with very little fuss. The chilli and fennel create a fragrant, caramelised crust on the steak, while the sweet roasted onion and capsicum relish brings acidity and freshness. Serve with peppery rocket leaves for a deliciously balanced lunch or dinner.

What is fennel?
Fennel is an aromatic Mediterranean herb with a delicate anise-like flavour. Both the bulb and seeds are used in cooking, but fennel seeds are particularly delicious with beef, adding warmth and a subtle sweetness as they toast in the pan.
What is balsamic relish?
Balsamic relish is a sweet, tangy and savoury condiment made by combining roasted vegetables with balsamic vinegar and herbs. In this recipe, roasted onion and capsicum provide natural sweetness, while balsamic vinegar adds acidity and depth.
Can I cook the steak on the BBQ?
Absolutely. A hot barbecue is perfect for this steak. Press the fennel, chilli and salt onto one side, then sear over high heat until caramelised. Turn once and cook to your preferred doneness.
What can I serve with steak and balsamic relish?
Rocket is a lovely simple accompaniment, but you could also serve the steak with a green salad, roasted vegetables or steamed greens. For a heartier meal, add roasted potatoes or sweet potato.
Can I make the balsamic relish ahead?
Yes. The relish can be prepared ahead and gently reheated, or served at room temperature. It’s also delicious the next day, making it a handy addition to other meals.
Is this steak recipe gluten-free?
Yes, provided your balsamic vinegar and other packaged ingredients are gluten-free. The recipe itself contains no wheat or gluten-containing ingredients.

This is Geoff Jansz’s wonderful all-year-round recipe, which I prepared earlier for a shoot. It’s perfect for a glorious winter’s day in Byron Bay, like the one peeking through my window today. I thought this might be just the tasty pick-me-up for those brave enough to fire up the BBQ — or simply an easy, delicious meal for anyone enjoying more temperate climes.
