For the chimichurri, finely chop the parsley and stir it with the olive oil, red wine vinegar, garlic, oregano, chilli flakes, salt and pepper. Leave to stand briefly so the flavours come together.
Preheat the oven to 220 °C (200 °C fan). Chop the courgette, pepper and red onion, toss with olive oil, salt and pepper and roast in the oven for 15–20 min, until the veg is soft and lightly charred in places.
Take the steaks out of the fridge in good time, pat them dry and season with salt and pepper. That way they cook more evenly in the pan.
Get a heavy frying pan very hot and sear the steaks well until browned on the outside and cooked to your liking inside. Then leave to rest briefly.
Take the roasted veg out of the oven and adjust the seasoning if needed. Give the chimichurri a quick stir before serving.
Slice the steaks, arrange them on plates with the veg and spoon the chimichurri over the top.
Good to know
Juicy steak and fresh chimichurri are simply a strong combination. Add roasted veg, and everything comes together easily.
Swaps
Entrecôte → rump steak (a little leaner, similar protein content); red pepper → green pepper (a little less sugar); red onion → shallot (milder in flavour, also contains plant compounds); olive oil → avocado oil (heat-stable, mostly monounsaturated fats)
Allergens
The recipe is naturally gluten-free and dairy-free; the main things to consider are the beef and a possible sensitivity to garlic or chilli. Use less chilli for children, and during pregnancy make sure the steak is well cooked through.
