Creating cheesy potatoes is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Potatoes: Peel and dice the russet potatoes into small cubes.
3. Boil the Potatoes: In a large pot, add the diced potatoes and cover with water. Bring to a boil and cook until tender, about 10-15 minutes.
4. Drain the Potatoes: Once tender, drain the potatoes and return them to the pot.
5. Mix Ingredients: In a large bowl, combine the sour cream, 1 cup of shredded cheddar cheese, milk, melted butter, garlic powder, onion powder, salt, and black pepper. Stir until well mixed.
6. Combine Potatoes and Mixture: Add the potato mixture to the bowl and gently stir until the potatoes are evenly coated.
7. Transfer to Baking Dish: Pour the potato mixture into a greased 9×13-inch baking dish.
8. Top with Cheese: Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
9. Add Breadcrumbs (Optional): If desired, sprinkle breadcrumbs over the cheese for added crunch.
10. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the cheese is bubbly and golden brown.
11. Garnish: If you’re using green onions, sprinkle them on top just before serving for a pop of color.
