Start by greasing your slow cooker with cooking spray or olive oil to prevent sticking.

Place cubed beef stew meat at the bottom of the slow cooker, then add diced potatoes on top.

In a bowl, combine ranch dressing mix, cream of mushroom soup, beef broth, sour cream, garlic powder, onion powder, and a sprinkle of salt and pepper. Stir until smooth.

Pour the creamy sauce over the layered beef and potatoes, ensuring everything is generously coated.

Cover and cook on low for 6-8 hours or high for 3-4 hours until beef is fork-tender and potatoes are soft.

Stir before serving, adjust seasoning if needed, and garnish with fresh parsley.
