I suppose it’s classed as retro these days, but I love steak diane.

My kids still think retro is a little bit cool, as is ‘old-school’ and ‘vintage’. I love how using a certain word can evoke a certain feeling that would be completely different if another word with the same meaning was used.

If I show my daughter a jacket or shoes from 20 years ago and call them vintage, she wants them. But if I told her they were from ‘back in the day’ they’re considered musty, old and unfashionable.

So this is my retro steak diane, re-made in casserole format.

Hand’s up here, it hasn’t got the poshness of a beautiful fillet steak, but it’s got all the taste, it can be made ahead, and you can serve a crowd without having to re-mortgage your house to pay for the ingredients.

This is what I made a couple of weeks ago for my regular visit to my grandad’s – where 12-15 of us get together every other week to turn his quiet little house into chattering, noisy, gossip-fest with a big meal followed by a diet-busting cake selection.
My grandad is 87 years old, and he takes it all in his stride when 4 kids are playing hide-and-seek around his recliner, and two babies are gurgling away with the odd baby-shriek thrown in there.

He loves us all visiting, but I think it makes the peace and quiet so much sweeter when we go home

Start it off on the hob, then you can continue to cook it on the hob, or in the oven, or you can use the slow-cooker or crockpot if you prefer.

I haven’t quite got into the swing of using my slow cooker again yet this Autumn. Having still not quite finished unpacking the kitchen boxes after our kitchen renovation was completed in March, I found my slow cooker pot the other day filled with cookie cutters and cake sprinkles.

Now I’ve found it, I’ll get some more slow-cooker recipes up here!

In the meantime, how about this Big Batch Chinese Beef, Slow Cooked Scottish Stew or Slow cooked Spicy Chicken Curry ????????

Ingredients

  • 2 tbsp vegetable oil
  • 1.5 kg braising beef or casserole beef (chopped into bitesizechunks)
  • 3 tbsp plain/all-purpose flour (you can use gluten free plain flour if required)
  • ½ tsp salt
  • ½ tsp freshly ground black pepper
  • 1 large onion (peeled and chopped)
  • 4 cloves garlic (peeled and minced)
  • 2 tbsp tomato puree/tomato paste
  • 4 tbsp brandy or whisky
  • 1 tbsp Worcestershire sauce
  • 1 Litre beef stock (3 stock cubes plus water is fine, or use homemade stock or bouillon for gluten free)
  • 300 g chestnut mushrooms, thickly sliced (thickly sliced)
  • 1 tbsp cornflour cornstarch mixed with 3 tbsp cold water, to make a slurry (optional)
  • 120 ml double (heavy) cream
  • small bunch fresh parsley roughly chopped

Instructions

  • Preheat the oven to 160C/320F.
  • Heat the oil in a large casserole pan over a high heat.
  • Place the chopped beef in a bowl and sprinkle on the flour, salt and pepper. Toss everything together, then add the beef to to the casserole pan. Cook for 6-8 minutes, turning regularly until browned all over (you can do this in batches if you like, but I find it doesn't impact the look or taste for this recipe to cook it all in one go)
  • Once the meat is browned, turn down the heat to medium and add the onion. Continue to cook for a further 3-4 minutes, stirring regularly until the onion starts to soften.
  • Stir in the garlic and tomato puree, cook for a further minute, then add the brandy/whisky, Worcestershire sauce, beef stock and mushrooms.
  • Stir everything together, being sure to scrape up any bits that may have stuck to the bottom of the pan. Bring to the boil, stir again then place a lid on the pan and place the pan in the oven* to cook for 3 hours, until the beef is tender. Check a few times during the last hour of cooking to ensure casserole doesn't cook dry. Add good splash of boiling water or stock if it starts to look too dry.
  • Once the meat is tender, remove from the oven. If you'd like to thicken the sauce a little, stir in the cornflour slurry.
  • Add the cream and stir, then top with freshly chopped parsley and a sprinkling of black pepper.
  • Serve with mashed potato and green veg such as broccoli, green beans and kale

Recipe Notes

Alternatively you could transfer to a slow cooker and cook on high for 5-6 hours or low for 7-8 hours, or, you could cook on a very low heat, on the hob, with the lid on for 2-3 hours.

    I’m so thrilled with this recipe! Thank you for sharing. I used a London broil roast sliced very thin and made it without mushrooms and I added a can of tomatoes with green chile peppers. So tender and delicious. Hubby shared leftover at work and was asked for the recipe. We recorded the cooking for our YouTube channel, I’d like to link back to you if you don’t mind.

    Hey. I have never cooked with alcohol before. I tried one dish once with red wine but it didn’t taste nice. I would like to give Themis recipe a go but would like to know if I should buy whiskey or brandy. Which one is better? And any particular brands? I don’t drink much so I’m not sure what to get
    Thanx

    Just had to let you know, we had this at the weekend. Put it in the slow cooker, went out for a walk. The aroma when we arrived home was amazing and just what we needed after a few hours out walking. Delicious.

    This looks delicious! I’ve been looking for a steak and mushroom pot pie recipe and I think this would make a great filling for a steak pot pie! I’m going to try it tomorrow and will let you know how it turns out!

      Hi Dawn, there are 300g chestnut mushrooms in the ingredient list (I think they might be known as brown-cap mushrooms in the US?). They’re added in in step 5.

    I haven’t had steak Dianne for years but remembered that I used to love it! I made this recipe yesterday exactly as is though I had to halve all the ingredients as there is only my wife & me – I gotta say this is amazing!!! I used the slow cooker as we needed to go out for the day, the smell when we came home…. wow!! – Even with the reduced ingredients there was enough left over to freeze for another couple of meals at least, and we both agreed we wont be leaving it too long before we have this again. Thanks so much for the recipe – sure winner in our house.
