Peel the potatoes and cut them into even-sized chunks. This helps them cook uniformly, preventing lumps in the mash.
Boil the Potatoes:
Place the potato chunks in a large pot, cover with cold water, and add a pinch of salt. Bring to a boil and cook until the potatoes are tender (about 15-20 minutes). To test doneness, pierce a potato with a fork; it should slide off easily.
Drain and Dry:
Drain the potatoes thoroughly and let them sit in the pot for a few minutes. This helps evaporate excess water, ensuring your potatoes are not watery.
Step 2: Mash and Season the Potatoes
Mash the Potatoes:
Using a potato masher or ricer, mash the potatoes until smooth. Avoid over-mixing, as this can make the potatoes gummy.
Add Creaminess:
Mix in the melted butter, sour cream, and heavy cream. Stir until everything is well incorporated. These ingredients create a smooth, creamy base that’s essential for a decadent casserole.
Season:
Season with salt and pepper to taste. You can also add garlic powder or a small amount of onion powder for additional flavor depth.
