Slow Cooked Steak Diane Casserole – a great make-ahead meal, just the thing if you’re feeding a crowd! I’ll show you how you can cook in the oven, on the hob or in the slow cooker.
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.
Hands up here, it hasn’t got the posh-ness 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.
Here’s what you’ll need:
How to make it
(full instructions and quantities in the recipe card below)
- Brown chunks of braising beef that have been tossed in flour, salt and pepper in a large casserole pan over a high heat, with a good splash of oil.
- Add onion and cook for a few minutes to soften, then stir in minced garlic, tomato puree, brandy/whisky, Worcestershire sauce, beef stock and mushrooms.
- Give everything a good stir, being sure to scrape up any bits that may have stuck to the bottom of the pan (lots of flavour in those bits!). Bring to the boil then place a lid on the pan and place the pan in the oven to cook for 3 hours, until the beef is tender.
- At this point remove from the oven, stir in double/heavy cream and top with freshly chopped parsley and a sprinkling of black pepper.
I love to serve it with mashed potatoes and green veg.
What to serve with Steak Diane Casserole
- Green Beans with Garlic and Parmesan
- Easy Spring Greens
- Simple Butter Pepper Carrots
- Crispy Roast Potatoes
- Creamy Mashed Potatoes
Make in the Slow Cooker:
Once you’ve brought the casserole to the boil in step 6, transfer the contents to your slow cooker and cook on high for 5-6 hours or low for 7-8 hours. This is the crockpot (<– affiliate link) I use. It has a searing function, so you can cook it all in the slow cooker without having to use a pan at all.
Make on the hob/stove top:
Instead of placing in the oven, you can cook this casserole over a very low heat on the hob/stovetop, with the lid on for 2-3 hours. Check the casserole and give it a stir a few times during cooking to prevent it from sticking. If it starts to look a little dry, you can add in a splash of water or stock

Notes
Make in the Slow Cooker:
If you're cooking in the slow cooker, you'll need to use less stock, as it won't evaporate as it does in the oven or on the hob/stove top.Reduce the stock by half to 500ml (a little over 2 cups).
Once you've brought the casserole to the boil in step 6, transfer the contents to your slow cooker and cook on high for 5-6 hours or low for 7-8 hours. This is the crockpot (<– affiliate link) I use. It has a searing function, so you can cook it all in the slow cooker without having to use a pan at all.
Make on the hob/stove top:
Instead of placing in the oven, you can cook this casserole over a very low heat on the hob/stovetop, with the lid on for 2-3 hours. Check the casserole and give it a stir a few times during cooking to prevent it from sticking. If it starts to look a little dry, you can add in a splash of water or stockCan I make it ahead?
Yes, make the casserole, then cool, cover and refrigerate it. Reheat in a lidded dish in the oven at 160C/320F for 35-45 minutes until piping hot throughout. Stir once or twice during this time to ensure it heats evenly. You can reheat on the hob if you prefer, although you will need to be careful when stirring so you don't break down the tender chunks of beef too much. Reheat over a low-medium heat, stirring often until piping hot throughout - which should take 10-15 minutes.Can I freeze it?
Yes, cool, cover and freeze the casserole, then defrost overnight in the refrigerator. Reheat as per the 'Can I make it ahead?' instructions above.Best cut of beef to use for Steak Diane Casserole:
- Chuck steak (also called braising steak) – comes from the forequarter - consisting of parts of the neck, shoulder blade, and upper arm.
- It’s a tough but very flavorful cut of meat. It has a lot of connective tissue, which needs long slow cooking to break down and become tender. This is the cut I always use for this casserole.
- Silverside (bottom round) – comes from the hindquarter – just above the back leg. This is a good alternative.
- It’s a leaner, inexpensive cut of meat with little marbling. The lack of fat means it doesn’t have as much flavour as chuck/braising steak, so make sure you use good quality stock to cook it in. It’s good for slow cooking, but must be cooked with moisture/liquid so doesn’t dry out and become tough.

Hello Nicky, I have been watching your video on Youtube and read the recipe for Slow Cooked Steak Diane Casserol and noticed it is for ten servings, I would like to cook the recipe and can work out the reductions of ingredients but would like to know what the reduction time would to cook for two people? thanks for all the great recipes
Hi Leigh, I would cook for about the same amount of time (possibly 30 mins less) – it still needs a fair amount of time for the beef to become tender. You may need to add a little more liquid too. Just check a couple of times and top up with a little water or stock if needed.
