How to Make Steak Diane Casserole?
This casserole comes together beautifully with slow cooking. Here’s how to create this delicious meal step by step.
Brown the Beef
Preheat your oven to 320°F (160°C). Toss the beef in flour, salt, and pepper until evenly coated. Heat oil in a large casserole pan over high heat. Add the beef and cook for 6 to 8 minutes, turning frequently, until browned all over. Remove and set aside.
Cook the Base
Reduce the heat to medium and add chopped onions to the same pan. Stir and cook for 3 to 4 minutes until softened. Add minced garlic and tomato paste, and stir for another minute to unlock the flavors.
Build the Sauce
Pour in brandy (or whisky) carefully and allow it to simmer for a minute. Add Worcestershire sauce, beef stock, and mushrooms. Stir well, scraping the bottom to lift any delicious crusty bits.
Cook Low and Slow
Bring the mixture to a boil, cover with a lid, and transfer to the oven. Slow-cook for 3 hours, checking occasionally to ensure it doesn’t dry out. Add a splash of boiling water or stock if needed.
Finish with Cream and Garnish
Once the meat is fork-tender, remove the casserole from the oven. Stir in the cream for a velvety finish and sprinkle with fresh parsley. Serve warm with a generous spoonful of sauce. You could also explore a Juicy Ribeye Steak Recipe as an alternative for another mouthwatering dish!
