Method
- Preheat your oven to 350°F. This ensures that the dish cooks evenly and is hot throughout. You want that cheesy goodness bubbling!
- Lightly grease or butter a 9×13 baking dish and set it aside. This step prevents the potatoes from sticking and makes cleanup easier.
- In a small bowl, combine the shredded cheeses (both cheddar and Monterey Jack) and toss to combine. Setting this aside helps it stay blended when adding to the potato mixture.
- Next, place the defrosted potatoes in a very large bowl. Toss them with 4 tablespoons of melted butter, salt, and pepper. This is the base that will soak up all the flavors!
- Stir in the sour cream and 2 cups of the combined cheese. The sour cream adds a creamy tang that you’ll absolutely love.
- In a large skillet over medium heat, melt 4 tablespoons of butter. Once melted, add the onions and cook until translucent, about 4 to 5 minutes. This step is crucial for developing flavor.
- Add the garlic and continue cooking, stirring frequently for 1 minute. You want the garlic fragrant but not burnt!
- Sprinkle with flour and continue cooking for another minute, stirring to combine. This will help thicken your sauce.
- Slowly whisk in the chicken stock until completely combined and smooth. Then gradually whisk in the milk until everything is smooth. Bring the mixture to a simmer.
- Season with salt and pepper, then continue cooking for three to four minutes until thickened. Remove from heat; this creates that wonderful creamy sauce.
- Pour the cream sauce over the potato mixture and gently fold to combine. This is where all the magic happens!
- Transfer this to your prepared baking dish and top with the remaining cheese. Every bit should be covered for maximum cheesiness!
- In a medium bowl, combine the remaining 4 tablespoons of melted butter with the cornflakes and toss to combine. This topping will add a delightful crunch.
- Spread the topping evenly over the layer of cheese. Cover with foil and bake for 20 minutes.
- Remove the foil and bake for another 15 to 20 minutes, or until the edges are bubbling and the cornflakes are golden brown. The beautiful golden color means it's done!
- Let it rest for 10 minutes before serving. This patience will pay off with perfect portions!
