Beef Stroganoff

I like this recipe cos it's great in summer or winter.  The cool thing about this recipe is that you can have it with pasta, rice or just on a crusty roll and rocket leaves.

Ingredients:

2 Tbsp extra-virgin olive oil
2 Tbsp butter
1 kg sirloin steak cut into thin strips
Salt
freshly ground black pepper
1 cup flour
1 tsp paprika
1 small onion, grated
250g sliced portabellini mushrooms ( I like these but you can use the ones you like)
1 cup beef stock
1/3 cup sour cream
1 Tbsp lemon juice
3 Tbsp chopped parsley

Method:

In a large pan heat the olive oil and butter.
Pat sliced meat dry.
Mix the flour and paprika in a plastic bag.
Season the meat with salt and pepper and coat in flour/paprika mix.
Shake off excess then add to very hot pan.
Add the grated onion and mushrooms.
Cook meat 5 to 6 minutes, turning occasionally.
Add stock to pan and stir while cooking until the sauce is thickened.  A minute or two.
Stir in sour cream and lemon juice.
Check the seasoning and adjust to your taste. ( I like adding quite a lot of black pepper at this stage.)
Add the parsley
Remove from heat.

Serves 4-6
