Good potatoes, especially freshly harvested new potatoes, are such a far cry from your typical Idaho russet as to be nearly a different vegetable altogether. Of course, you can also make this with storage potatoes when new potatoes are not available and as long as you choose good quality ones the stew will be delicious.
1 Tbsp olive oil
6-8 cloves garlic, minced
1 large onion, finely chopped
1/4 lb shiitake mushrooms, stemmed and sliced
1 lb ground beef
1 1/2 - 2 lbs new potatoes, cubed
Beef stock and/or water
Salt and pepper to taste
1/4 cup chopped fresh parsley
Heat the olive oil in a large pot. Add the garlic and onion and saute for about 2 minutes, then add the shiitakes and saute for another 2-3 minutes. Add the beef and brown thoroughly. Add the potatoes along with enough stock and/or water to just cover them. Bring to a boil, then simmer until the potatoes are tender, about 15 minutes. Add and salt and pepper to taste, then stir in the parsley.
