Scale
Potatoes
- 3 lbs. Yukon gold potatoes ($2.93)
Dairy and Fats
- 1/4 cup butter ($0.53)
- 2 cups milk (any kind, including plant-based, $0.96)
- 3 1/2 cups extra sharp cheddar cheese (divided, $3.21)
- 1/2 cup sour cream ($0.91)
Vegetables and Seasonings
- 1/2 onion ($0.35)
- 2 cloves garlic ($0.16)
- 1/2 tsp salt ($0.02)
Other
- 1/4 cup all-purpose flour ($0.05)
- 1 cup corn flake cereal (crushed, $0.44)
Instructions
- Preheat oven: Set your oven to 375°F (190°C). Grease a 9×13-inch casserole dish to prevent sticking.
- Prepare potatoes: Peel the Yukon gold potatoes and dice them into uniform pieces for even cooking. Finely chop the onion and mince the garlic cloves.
- Cook potatoes: Place the diced potatoes in a large pot of water. Bring to a boil and cook for 8-10 minutes until they are fork-tender. Drain the potatoes using a colander and transfer them to the prepared casserole dish.
- Make cheese sauce: In a large saucepan over medium heat, melt the butter. Add the chopped onion and a pinch of salt; cook for about 3-4 minutes until softened. Add the minced garlic and cook for an additional minute. Sprinkle in the flour, stirring constantly to combine. Gradually pour in the milk, whisking constantly to avoid lumps. Continue cooking and stirring until the mixture thickens. Stir in 2 cups of the shredded cheddar cheese and the sour cream until smooth and melted.
- Combine with potatoes: Pour the cheese sauce over the cooked potatoes in the casserole dish. Gently stir to coat all the potatoes evenly.
- Add topping: Sprinkle the crushed corn flakes cereal evenly over the casserole. Then, top with the remaining 1.5 cups of shredded cheddar cheese.
- Bake: Place the casserole in the preheated oven and bake for 20 minutes, or until the cheese is bubbly and golden brown. Remove from oven and let sit for a few minutes before serving.
Notes
- For an extra flavor boost, add cooked bacon bits or chopped green onions on top before baking.
- You can substitute the cheddar cheese for Monterey Jack or Pepper Jack for a different flavor.
- Use gluten-free flour if you need a gluten-free option; the casserole will still turn out delicious.
- For a creamier result, mix some extra sour cream or a splash of heavy cream into the cheese sauce.
