Colm O'Gorman: Butter is the secret ingredient in this fabulous fillet steak with roasted root veg
Served with a fresh, sharp, herby chimichurri, this steak dinner is very special.
Butter really does make most things taste better, and this is certainly true for this week’s recipe which really elevates a steak dinner.
Basting a very good steak in foamy melted butter, garlic and fresh thyme for the last few minutes of cooking adds bags of flavour.
