Instructions:

1. Heat 2 tablespoons of oil in a skillet over medium-high heat. Season the beef blade steaks with salt and pepper, then brown them on both sides in the skillet. Transfer the browned steaks to a slow cooker.
2. In the same skillet, sauté the sliced onions and mushrooms in the remaining 2 tablespoons of oil until softened and slightly browned, about 5-6 minutes.
3. Add the chopped fresh thyme and mild paprika to the skillet with the onions and mushrooms, and cook for an additional minute to enhance the flavors.
4. Transfer the onion and mushroom mixture to the slow cooker, ensuring the beef steaks are evenly coated.
5. In a separate bowl, whisk together the chicken broth, dry sherry, and flour until smooth. Pour this mixture over the beef and mushrooms in the slow cooker.
6. Cover and cook on low for 6-8 hours (or 4-5 hours on high) until the beef is tender and fully cooked.
7. Once the cooking time is up, remove the beef steaks from the slow cooker and set them aside.
8. Turn the slow cooker to high and stir in the heavy cream and chopped fresh parsley. Mix well.
9. Coat the beef steaks with the mushroom sauce in the slow cooker, then cover and continue cooking on low for an additional 10 minutes to allow the flavors to meld.
