What can i add to my beef casserole to make it tastier?

[Jojay]

I'm making a beef casserole with onions, carrots, celery, potato and mushrooms.

I make the sauce from beef stock and tomato puree and add a bay leaf and some mixed herbs, and seasoning.

The sauce can tast a bit bland and watery. What else can I add to made it richer?

This is funny - everyone has their own secret ingredient.

It's starting to look like answers to a thread entitled "what's in your cupboard?".

Bovril, quite a good sized gloop.

bay leaves

Well after adding glug of red wine and some worcester sauce, I can officially declare that it ws YUM!!

Thanks all
