Ingredients
Gather your ingredients like you’re prepping for a cozy night in. The star of the show is, of course, the mashed potatoes.
But don’t worry—I won’t judge if you use store-bought. Here’s what you’ll need:
- 4 cups mashed potatoes (homemade or store-bought)
- 1 cup shredded cheddar cheese (plus extra for topping)
- ½ cup sour cream
- ½ cup cooked bacon, crumbled (because everything’s better with bacon)
- ¼ cup green onions, chopped
- 2 tbsp butter, melted
- 1 tsp garlic powder (trust me on this)
- Salt and pepper to taste
Step-by-Step Instructions
- Preheat your oven to 375°F (190°C). Because nobody likes a cold casserole.
- Mix the mashed potatoes, sour cream, garlic powder, and half the cheese in a large bowl.
If it looks like a cheesy cloud of happiness, you’re doing it right.
- Spread the mixture into a greased baking dish. Smooth the top like you’re frosting a cake—minus the pressure.
- Sprinkle the remaining cheese, bacon, and green onions on top. This is where the magic happens.
- Drizzle with melted butter for that golden, crispy finish.
Bake for 20-25 minutes until bubbly and slightly browned.
- Let it cool for 5 minutes—if you can resist diving in immediately. Serve and watch it disappear.
Storage Instructions
Leftovers? Ha, good one.
But if you somehow manage to have any, store them in an airtight container in the fridge for up to 3 days. To reheat, pop it in the oven at 350°F (175°C) until warm. For freezer storage, wrap tightly and freeze for up to 2 months.
Pro tip: freeze individual portions for quick weeknight sides.
