Beef, sweet potato and parsnip gratin

I have made so many things lately but I just haven't had time to upload them and I've also forgotten to take photos. Last night I made a really tasty dish from undervarttak.blogspot.se. I mixed some parsnip in there together with the sweet potato since I really love the flavour of parsnip. Served it with some steamed broccoli because I thought it needed some greens. Result was deliciousness.

Ingredients
serves 4
1 medium sized sweet potato, peeled and thinly sliced
2 medium sized parsnips, peeled and thinly sliced
500 g ground beef
1 red onion, finely diced
400 ml coconut milk
2 garlic cloves, crushed
½ red chili, finely diced
1 tsp grated ginger
Parsley
Salt and pepper to taste

Preheat the oven to 200 degrees Celsius.
Prepare the sweet potato and parsnip by peeling and slicing them.
Heat a large frying pan to medium heat and add some butter. Fry the onion for a couple of minutes. Add the ground beef and season with salt and pepper. Once browned, add the coconut milk, garlic, chili,ginger and parsley. Mix around and let it simmer for about 3-4 minutes. Add the sweet potato and parsnip and carefully mix around. Let it simmer again for a minute or two.
Pour into an ovenproof dish and cook in the oven for 30-40 minutes (depending on the thickness of the root vegetables). Enjoy with some steamed vegetables or a salad.
