Grilled Steak with Rosemary Roasted Potatoes and Steamed Broccoli

Preparation Steps

1. Preheat your oven to 200°C (fan). Scrub the potatoes thoroughly, then cut them into even wedges of roughly 3cm — leave the skins on. The skin is rich in valuable dietary fibre that your gut microbiome will love.

2. Season the potatoes: place the wedges in a large mixing bowl and toss with 1 tbsp of olive oil, the smoked paprika, garlic powder, rosemary leaves stripped from the stalks, salt and pepper. Mix well to coat every piece evenly.

3. Roast the potatoes: arrange them in a single layer on a baking tray lined with baking paper. Roast for 45–50 minutes, turning halfway through, until golden and lightly crisp. Set aside.

   💡 Microbiome tip: To maximise the prebiotic resistant starch content, allow the potatoes to cool in the fridge for 4–12 hours after cooking, then gently reheat at a low temperature (150°C, 10 minutes) before serving. This simple step can increase the resistant starch content by 2 to 3 times — a powerful fuel source for your beneficial gut bacteria!

4. Remove the steaks from the fridge approximately 20–30 minutes before cooking. This is essential for achieving an even cook and avoiding the thermal shock that can toughen the meat. Pat them dry gently with kitchen paper.

5. Marinate the steaks lightly (optional but recommended): brush them with the Dijon mustard, a drizzle of olive oil, a few rosemary leaves, salt and pepper. Leave to rest for 10 minutes at room temperature.

6. Steam the broccoli: rinse the florets and place them in a steamer basket over a pan of boiling water. Cover and cook for exactly 5–7 minutes — no longer! Brief steaming preserves the fibre, vitamin C, vitamin K, and — most importantly — sulforaphane, a natural anti-inflammatory compound that supports the gut lining. The broccoli should remain slightly tender-crisp and vivid green.

7. Season the broccoli off the heat with a squeeze of fresh lemon juice and a pinch of salt. The lemon brightens the flavour while also helping your body absorb the non-haem iron present in the vegetable.

8. Heat a cast-iron pan (or griddle pan) over a high heat for 2 minutes, with no added fat. Once smoking hot, cook the steaks:

   • Rare: 1 min 30 seconds each side
   • Medium: 2 min 30 seconds each side
   • Well done: 3 min 30 seconds each side Avoid pressing the meat down with a spatula during cooking — this forces out the juices and dries the steak out.

9. Rest the meat for 3–5 minutes off the heat, loosely covered with a sheet of foil. Resting allows the muscle fibres to relax and the juices to redistribute throughout the steak, making it more tender and easier to digest.

10. Plate up: arrange the steak, roasted potatoes and steamed broccoli on each plate. For optimal digestion, avoid alternating rapidly between large mouthfuls of meat and potato — chew slowly and take the time to savour each element. Thorough chewing is the very first step towards healthy digestion!

🌿 Gut-Friendly Advice

If you suffer from irritable bowel syndrome (IBS) or follow a low-FODMAP diet, here are a few simple adaptations:

• Swap the potatoes for roasted sweet potato (cooled then reheated): its gentler fibres are better tolerated and produce less excessive fermentation.
• Reduce the broccoli to under 100g per portion, or replace it with steamed carrots or courgettes, which are naturally low in fructans and very gentle on the gut.
• Garlic powder can be replaced with garlic-infused oil (remove the garlic pieces before use): you get all the flavour without the irritating fructans.

🔬 Did You Know?

Researchers at Flinders University in Australia have shown that the resistant starch found in cooled potatoes may help neutralise certain potentially harmful compounds produced during the digestion of red meat in the large intestine — by feeding the bacteria that produce butyrate, a short-chain fatty acid that is protective for the colon. Yet another reason not to skip the cooling step!
