Slow cooker flat iron steak

For a meal with all the tenderness of fillet steak but without the price tag, I can thoroughly recommend this slow cooker flat iron steak recipe. What's more, the cooking juices can be transformed into the most incredible sauce.

📝 Ingredients

• 12 ounces / 350 grams flat iron steak
• 8 ounces / 225 grams sliced white mushrooms
• 1 medium onion (thinly sliced)
• 1 beef stock pot dissolved in 1 cup boiling water
• 1 tablespoon tomato puree or tomato paste
• 2 tablespoons Worcestershire sauce
• 1/2 cup / 120 ml double or heavy cream
• 1 to 2 tablespoons sunflower oil
• 1/2 teaspoon salt (optional)
• 2 tablespoons cornflour or cornstarch (or more as needed)
• 1 to 2 tablespoons finely chopped parsley (optional (for garnish))

👨‍🍳 Instructions

1. 1Slice the onions and mushrooms and arrange them on the bottom of your slow cooker.
2. 2Season the steak lightly with salt (optional) and heat one or two tablespoons of oil in a frying pan. When the oil is hot, sear the steak for 60 to 90 seconds per side, until lightly browned.
3. 3Arrange the steak on top of the onions and mushrooms.
4. 4Combine the Worcestershire sauce and tomato puree with the stock and pour it over the meat and vegetables in the slow cooker. Cook on low for 6 to 7 hours until the onions are softened and the meat is tender.
5. 5Carefully remove the meat from the slow cooker, arrange it on a serving plate and keep it warm while you thicken the gravy. Take care - the meat will be very soft and inclined to fall apart.
6. 6Pour the stock, mushrooms and onions into a small saucepan.
7. 7To thicken the gravy mix 2 tablespoons of cornflour with a splash of water to a smooth paste. Stir it into the sauce over a moderate heat until the sauce thickens.
8. 8Once the sauce is the consistency of thick gravy, stir in the cream.
9. 9Pour the sauce over the meat and optionally garnish with chopped parsley. Serve hot with your choice of vegetables.
