Preheat oven to 350 F. Prepare large baking sheet with parchment paper.

Place diced potatoes into the medium bowl.

In a small jar combine butter, sweet paprika and onion powder. Mix all ingredients.

Add the mixture to potatoes and mix all ingredients together to cover potatoes evenly.

Spread evenly on baking sheet.

Season with salt and pepper.

Bake for 1 hour or 1 hour and 20 minutes. Add more time if potatoes are still uncooked. For small diced potatoes use less time.
