The classic flavors of Steak Diane come together in your slow cooker with this breezy recipe made with chuck steak, cooking cream, Worcestershire sauce, tomato sauce, brown onion, and garlic.

To make Steak Diane in your slow cooker or crockpot, sear the steak, mix the sauce, pour over the steak, and cook on low for 4 hours.

The slow cooker does the heavy lifting, allowing flavors to meld perfectly while you go about your day. I love making this on busy weekdays for a hassle-free, satisfying dinner.

Slow Cooker Steak Diane Ingredients

• 1 kg piece of chuck steak
• 320 ml of cooking cream
• 4 tbsp of Worcestershire sauce
• 4 tbsp of tomato sauce
• 1 brown onion, finely diced
• 2 tbsp of olive oil (if searing meat)
• 2 garlic cloves, minced
• Mushrooms, optional (use as many as you like)
• Chopped parsley to taste

How To Make Slow Cooker Steak Diane

1. Prepare the steak: If desired, sear the steak in a frying pan with olive oil until it is browned on all sides. This step adds an extra layer of flavor but is optional and can be skipped if short on time.
2. Add to slow cooker: Place the seared or raw steak directly into the slow cooker, ensuring it is positioned centrally to allow even cooking throughout.
3. Mix the sauce: In a mixing bowl, thoroughly combine the cooking cream, Worcestershire sauce, tomato sauce, finely diced onion, and minced garlic until the mixture is smooth and well-blended.
4. Pour over steak: Carefully pour the prepared sauce mixture over the steak in the slow cooker. If you are using mushrooms, add them at this stage to allow them to cook alongside the steak.
5. Cook: Cover the slow cooker with its lid and cook on the low setting for 4 hours, allowing the flavors to meld and the steak to become tender.
6. Thicken the sauce (optional): If you prefer a thicker sauce, remove the meat and set it aside. Turn the slow cooker to high, and let the sauce simmer until it reaches your desired consistency.
7. Finish and serve: Stir in the chopped parsley to the sauce, return the steak to the slow cooker if removed, and serve immediately.

How do I know when the steak is done?

The steak is done when it is tender and easily pulled apart with a fork. This usually happens after about four hours of cooking on low. If you have a meat thermometer, the internal temperature should be around 160°F (71°C) for well-done meat.

Recipe Tips

• Searing the steak: For extra flavor, sear the steak in a hot pan with olive oil before placing it in the slow cooker. This step caramelizes the meat, adding a depth of flavor that’s worth the extra effort.
• Using fresh ingredients: Whenever possible, use fresh garlic and onions instead of pre-minced or powdered versions. Fresh ingredients will enhance the overall taste of your dish and make it more aromatic.
• Thickening the sauce: If you prefer a thicker sauce, remove the steak once cooked and simmer the sauce on high in the slow cooker. This helps reduce the sauce to your desired consistency without overcooking the meat.
• Adding mushrooms: For an earthy flavor, add a mix of different mushroom varieties. Button, cremini, and portobello mushrooms all work well. Slice them thinly and stir them into the sauce at the beginning of cooking.
• Resting the steak: After cooking, let the steak rest for a few minutes before serving. This helps the juices redistribute within the meat, making it juicier and more flavorful when you finally dig in.

Recipe Variations

• Adding red wine: For a richer flavor, substitute half of the cooking cream with red wine. This variation adds depth and a slightly tangy note to the sauce, making it more complex and delicious.
• Using different meats: Try using other cuts of beef like ribeye or sirloin for a different texture. You can also experiment with pork tenderloin or chicken thighs for a unique twist on the classic Steak Diane.
• Spicy twist: Add a pinch of red pepper flakes or a splash of hot sauce to the sauce mixture. This will give your Steak Diane a subtle kick, perfect for those who enjoy a bit of heat in their meals.
• Herb variations: Experiment with different herbs like thyme or rosemary instead of parsley. These herbs will add a distinct flavor profile to your dish, making it uniquely yours while still retaining the essence of Steak Diane.
• Creamy mushroom sauce: Increase the amount of mushrooms and blend part of the cooked mixture for a creamy mushroom sauce. This creates a luxurious texture and an intensified mushroom flavor that pairs perfectly with the tender steak.

What to Serve with Steak Diane

Serve your Slow Cooker Steak Diane with creative sides like roasted garlic mashed potatoes, honey-glazed carrots, and Parmesan asparagus.

For a unique twist, try truffle mac and cheese, or a citrusy arugula salad. You can also pair it with balsamic Brussels sprouts or creamy polenta for a delicious combination.
