Preheat the oven to 200 degrees. Rub the beef with olive oil and season well.
Heat a non-stick frying pan over a medium-high heat. Sear the beef for 2 mins each side and place in the oven for 15 mins for rare and 20 mins for medium rare (you may have to adjust timings depending on the size of the beef).
Remove from the oven, cover with foil and let it rest. Slice into thin pieces and set aside.
Cut your baguette into thin slices and lay on a oven tray lined with baking paper.
Use olive oil spray or a pastry brush with olive oil and rub/spray baguette pieces with olive oil. Season well. Bake for about 12-15 mins or until just turning golden. Remove, let cool.
Mix together the crème fraîche, goats cheese and horseradish in a small bowl and season to taste. Keep in the fridge until ready to serve.
To assemble: Spread each crostini with quince paste, followed by horseradish cream mix (be generous), some sliced eye fillet beef and a sprinkling of chopped chives. Season well and enjoy!
