The Full Easy Slow Cooker Steak Diane Casserole Recipe

Ingredients

2 tbsp oil
3.3 lb (1.5 kg) braising beef or casserole beef, chopped into bite-sized chunks
3 tbsp all-purpose flour (gluten-free flour can be used if needed)

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
1 tbsp Worcestershire sauce
4 ¼ cups (1 liter) beef stock (3 stock cubes plus water is fine, or use homemade stock or bouillon for gluten-free)
10.5 oz (300 g) chestnut mushrooms, thickly sliced
1 tbsp cornstarch mixed with 3 tbsp cold water (optional, for thickening)

½ cup (120 ml) heavy cream
Small bunch fresh parsley, roughly chopped
Pinch of black pepper

Instructions

Preheat your oven to 320°F (160°C, fan).
In a large casserole pan, heat the oil over high heat. This will help to sear the beef, locking in the flavor.
In a bowl, combine the chopped beef with flour, salt, and pepper. Toss to coat the beef evenly. Then, add it to the hot casserole pan. Cook for 6-8 minutes, turning regularly until browned all over. This step enhances the flavor of the beef.
Once the beef is browned, reduce the heat to medium and add the chopped onion. Cook for an additional 3-4 minutes, stirring regularly until the onion starts to soften.

Stir in the minced garlic and tomato puree, cooking for another minute. Then, add the Worcestershire sauce, beef stock, and sliced mushrooms. Mix everything well, scraping up any bits stuck to the bottom of the pan.
Bring the mixture to a boil. Cover the pan with a lid and transfer it to the oven. Cook for 3 hours, until the beef is tender. Check occasionally during the last hour to ensure it doesn’t dry out; add a splash of boiling water or stock if needed.
After 3 hours, remove the casserole from the oven. If you prefer a thicker sauce, stir in the cornstarch slurry.

Add the heavy cream and stir well to combine. Top with freshly chopped parsley and a sprinkle of black pepper for a touch of freshness.
Serve your delicious beef casserole with mashed potatoes and green vegetables like broccoli, green beans, or kale for a wholesome meal.
