Start hard-boiling the eggs. They’ll need about 12 minutes in boiling water. Once done, cool them in cold water.
While that’s going on, peel and slice the sweet potatoes thinly.
Finely chop the onions and garlic, and add with the sweet potato slices to a mixing bowl.
Salt it to taste, it will take up quite a lot of salt.
Peel and cut the hard boiled eggs to round slices.
Give the sour cream a good stir to make it creamier.
Take an oven proof casserole dish and layer half of the onion and sweet potato mix across the bottom.
Layer all the slices of egg on top next.
Sprinkle with a little more salt, and half the pepper and paprika.
Put a layer of sour cream (in dollops) on the top of every egg slice.
Layer over the rest of the sweet potato and onion mix.
Spread out the remaining sour cream over the top and finish by adding the rest of the pepper and paprika.
Add the lid (or cover with foil) and bake at 200°C/390°C for 40 mins.
Take off the lid or the foil, then bake for another 30 mins.
Done! Let cool slightly, and serve. It’s great alone or with a fresh salad on the side.
