🛒 Ingredients
- 5 lbs Russet potatoes (or Yukon Gold), washed and cut into 1-inch bite-sized cubes
- 1 lb bacon, cooked until crispy and crumbled
- 2.5 cups sharp cheddar cheese, freshly shredded
- 1 cup sour cream (plus extra for dolloping on top before serving)
- 1/2 cup heavy cream (or whole milk)
- 1/4 cup (half stick) unsalted butter, melted
- 1 tbsp garlic powder
- 1 tbsp onion powder
- 1 tsp smoked paprika
- Salt and black pepper (to taste)
- 1/2 cup fresh chives or green onions, finely chopped (for garnish)
👩🍳 Step-by-Step Instructions
1. Par-Boil the Potatoes
Place your cubed potatoes into a large pot and cover them completely with cold water. Add a generous pinch of salt. Bring the water to a rolling boil over high heat and cook the potatoes for 8–10 minutes, just until they are slightly fork-tender but still holding their cubed shape firmly. Drain the potatoes thoroughly in a colander and transfer them to a large clear mixing bowl.
2. Create the Rich Garlic Cream Mixture
In a medium bowl, whisk together the sour cream, heavy cream, melted unsalted butter, garlic powder, onion powder, smoked paprika, salt, and black pepper until completely smooth.
3. Toss and Layer
Preheat your oven to 375°F (190°C). Spray a large 9×13 glass baking dish or a disposable aluminum foil pan generously with non-stick cooking spray. Pour the garlic cream mixture directly over the warm drained potatoes in your large mixing bowl. Add half of the crumbled bacon and 1 cup of the shredded cheddar cheese. Toss gently with a large spatula until all the potato cubes are evenly coated, then transfer the mixture into your prepared baking pan, smoothing out the top.
4. Bake to Golden Perfection
Cover the pan tightly with aluminum foil and bake in the preheated oven for 30 minutes. Remove the pan from the oven and carefully peel back the foil. Scatter the remaining 1.5 cups of shredded cheddar cheese and the rest of the crispy crumbled bacon evenly over the entire surface. Return the uncovered casserole to the oven for another 12–15 minutes, until the cheese is completely melted, gooey, and bubbling beautifully around the edges.
5. Top and Serve Hot
Remove from the oven and let it rest for 5 minutes to set. Right before serving, use a spoon to add neat, clean dollops of cold sour cream across the hot cheese surface. Finish with a heavy shower of freshly chopped green chives. Slice into large squares and serve screaming hot!
💡 Chef’s Pro-Tips for Success
- Leave the Skin On or Off? This is completely up to your personal preference! Leaving the skins on Russet or Yukon Gold potatoes adds a wonderful, rustic texture to the casserole, while peeling them yields an ultra-soft, velvety finish.
- Perfect Sour Cream Dollops: For that picture-perfect, viral look shown in your video, make sure to add your cool sour cream dollops after the casserole comes out of the oven. If you bake sour cream on top under direct heat, it can melt down completely and lose its beautiful, pillowy shape.
- Make It a Main Course: You can easily turn this side dish into a complete, standalone dinner by folding in 2 cups of cooked, shredded rotisserie chicken or sliced smoked sausage directly into the potato mixture before baking!
