Peel the 500 g of sweet potatoes and cut them into 3 cm cubes. Peel the onion and chop it really finely.
Cook the sweet potatoes
Put the cubes in the saucepan, cover with cold salted water and bring to a boil. Let them cook at a gentle simmer for 15 min, until a knife slides in with no resistance.
Cook the onion
Meanwhile, heat half the olive oil in the skillet over medium heat and cook the chopped onion for 3 min, until it turns translucent. Tip it into the mixing bowl and let it cool a bit.
Shape the meatballs
Add the 400 g of ground meat to the bowl with the onion, plus salt and pepper. Mix by hand and shape 8 walnut-sized meatballs.
Cook the meatballs
Heat the rest of the oil in the skillet over medium-high heat and cook the meatballs for 8 min, turning them, until they're golden with no pink left in the middle (70 °C minimum).
Tip · Only flip the meatballs once they release from the skillet on their own. Cut one in half to make sure there's no pink left in the center.
Drain the sweet potatoes
Drain the sweet potatoes in the colander, then put them back in the empty saucepan on the turned-off burner for 1 min so they dry out.
Mash them up
Warm the milk for 30 s in the small saucepan or the microwave. Mash the sweet potatoes with the butter, pour in the milk a little at a time, then season with salt and pepper.
Tip · Pour in the warm milk bit by bit as you mash: sweet potatoes don't all soak it up the same way, so stop when you like the texture.
Plate and serve
Split the mash between two plates and set the meatballs on top. Drizzle the pan juices over everything.
And there you go, it's readyCheck off every step to celebrate.
