- Pour the sour cream mixture over the potatoes, ensuring they are well-coated.
Step 5: Bake Covered

Step 6: Add Cheese and Bake Uncovered
- After 45 minutes, carefully remove the foil.
- Sprinkle shredded cheddar cheese evenly over the top of the potatoes.
- Return to oven uncovered for an additional 15 minutes or until cheese is bubbly and golden brown.
