Prepare: Lightly spray your slow cooker with non-stick cooking spray.
Layer: Add the baby potatoes to the bottom of the pot, then layer the beef stew meat directly on top.
Whisk: In a small bowl, combine the melted butter, olive oil, garlic, and all seasonings (ranch, paprika, onion powder, pepper, salt, and chili flakes).
Coat: Pour the garlic butter mixture over the beef and potatoes. Stir gently to ensure everything is coated.
Liquid: Carefully pour the beef broth around the inner edges of the crockpot (try not to wash the seasoning off the meat).
Slow Cook: Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours until the beef is fork-tender.
Finish: Give it a final stir to emulsify the juices, taste for salt, and serve hot.
