Ingredients
- Bacon: Brings smoky depth and savory crunch Look for thick cut strips for maximum flavor and easier crumbling
- Russet potatoes: These make the fluffiest mash with just the right texture Select firm large potatoes with no visible green spots
- Canola oil: Helps crisp up the potato skins for roasting You can swap in another neutral oil if you prefer
- Salted butter: The base of any comforting mash Use softened butter for easier mixing and richer flavor
- Sour cream: Adds tang and extra creaminess Opt for full fat and let it come to room temperature
- Whole milk: Helps achieve creamy yet scoopable potatoes Warm it slightly so it blends easily
- Grated cheddar cheese: Melts beautifully and gives that golden bubbly topping Choose sharp cheddar if you like a bolder hit
- Seasoned salt: Boosts flavor beyond plain salt Try to use your favorite blend for the best result
- Green onions: Bring a fresh finishing touch Look for firm bright stalks wash and slice thin
- Salt and pepper to taste: Classic seasoning for balance and extra flavor Add to taste after mashing
Step-by-Step Instructions
- Prep the Ingredients:
- Remove butter sour cream and milk from the fridge to take the chill off This small step makes them mix in smoothly
- Roast the Potatoes:
- Scrub potatoes dry them and rub generously with canola oil Place directly on a baking sheet and roast at 400 F for about forty minutes until a sharp knife slices through with no resistance This step sets up that classic baked potato flavor
- Cook the Bacon:
- While potatoes bake cook the bacon on low in a large skillet Watch closely and flip with tongs as the edges curl Continue slowly so fat renders and bacon becomes evenly crisp Move to a paper towel lined plate to cool This method prevents burnt edges
- Prep the Potatoes:
- Once roasted lower oven temp to 350 F Retain skins on two potatoes Peel the rest Slice all potatoes into thirds and add to a large mixing bowl The mixed skins offer more texture and homey flavor
- Mix with the Classic Fixings:
- Crumble bacon saving some for garnish Add most of the bacon butter sour cream cheese and seasoned salt to the bowl with potatoes Mash together You want a rustic texture not totally smooth
- Add the Milk:
- Pour in milk a splash at a time mashing gently between additions Stop when you reach your preferred consistency Some like it ultra creamy others a touch chunky
- Assemble the Casserole:
- Grease a nine by thirteen baking dish Spoon in the potato mixture Level it off Sprinkle reserved bacon and extra cheddar in an even layer over the top
- Bake and Finish:
- Bake uncovered for twenty to twenty five minutes until hot with bubbly cheese Finish with a big scatter of fresh green onions just before serving

Cheddar cheese is my favorite part of this recipe A sharp variety melts into the potatoes and adds that perfect golden top Every year my niece insists on being the one to sprinkle the cheese on before it bakes and her pride makes serving it even sweeter
