Turn the oven on to 180 °C, convection if you can. Take the roast out of the fridge so it's not ice cold.
Season the roast
Season the roast with salt and pepper on all sides, then rub it with the dried thyme (1 tsp total).
Sear the roast
Heat the olive oil (1 tbsp) in the Dutch oven over high heat. Sear the roast 2 to 3 min per side, until nicely browned.
Tip · Don't move the roast while it sears, it lets go of the pot on its own once the crust is nicely browned.
Add the prunes and honey
Turn off the heat, drizzle the roast with the honey (1 tbsp) and add the prunes around it with 10 cl of water. Put the Dutch oven in the oven at 180 °C.
Peel the celery root
While the roast cooks, peel the celery root (380 g) with the vegetable peeler, then cut it into 2 cm cubes.
Cook the celery root
Fill a saucepan with water, add a pinch of salt and bring it to a boil. Drop in the celery root cubes and simmer until a knife slides in with no resistance.
Drain the celery root
Drain the celery root well in the colander and let it steam 2 min so it dries out. Put it back in the empty saucepan.
Mash
Mash the celery root with a fork or potato masher. Add all the butter (30 g) and all the crème fraîche (9 cl), add pepper and stir over low heat.
Tip · The celery root has to be really well drained, or the mash turns runny and bland.
Rest and slice
Check that the roast hits at least 70 °C inside, with no pink, otherwise give it another 5 to 10 min. Take it out, cover it with foil for 10 min, then slice it.
Plate up
Divide the mash between two plates and lay the roast slices on top. Spoon the prunes and pan juices over everything.
And there you go, it's readyCheck off every step to celebrate.
