Ingredients You’ll Need

Water (to cover potatoes while cooking): This will ensure the potatoes cook evenly and are tender.
2 chicken bouillon cubes: Adds a savory depth of flavor that elevates the mashed potatoes.
1 tsp. salt: Essential for flavor enhancement; feel free to adjust according to taste.
¼ cup salted butter, room temperature: Brings richness and creaminess to the potatoes.
16 oz. sour cream, room temperature: Provides tanginess and contributes to a velvety texture.
3 cups sharp cheddar cheese, grated and divided: Sharp cheddar enhances the flavor and melts perfectly into the mash.
Sliced chives or green onion: These add a fresh, vibrant touch, both in flavor and presentation.

How to Make Cheesy Mashed Potatoes

Prepare the Potatoes: In your slow cooker, place the peeled and cubed russet potatoes. Pour in enough water to cover them, then add the chicken bouillon cubes.
Cook: Cover and cook on HIGH for about 3.5 hours, until potatoes are tender and fork easily.
Drain: Once cooked, carefully drain the potatoes.
Mix in Creaminess: Add the salt, room temperature butter, sour cream, and 1 cup of the grated sharp cheddar cheese.
Mash: Using a hand mixer, blend everything together until creamy and smooth. Be cautious not to over-mix, as you want to keep some texture.
Add More Cheese: Sprinkle the remaining 2 cups of cheddar cheese on top of the mashed potatoes.
Melt the Cheese: Cover the slow cooker again; let the cheese melt for about 10 minutes. You can crank the slow cooker up to high to speed this step.
Garnish: After the cheese has melted, top your cheesy mashed potatoes with sliced chives or green onions if desired.
Serve & Enjoy: Scoop a hearty serving onto your plate, and dig in.

Storing & Reheating

Store any leftovers at room temperature for no more than two hours, after which they should be refrigerated in an airtight container for up to 3-5 days. If you need to keep them longer, consider freezing your cheesy mashed potatoes. They can last up to three months in the freezer when placed in a freezer-safe container. When it’s time to enjoy again, reheat in the microwave or oven until warmed through. Just note, the texture may alter slightly after freezing; you can refresh the flavor by mixing in a bit of warmed butter or sour cream.

Chef’s Helpful Tips

Avoid over-mixing the potatoes to prevent a gummy texture. Aim for just a few seconds of mixing until combined and creamy.
Ensure your butter and sour cream are at room temperature to help everything incorporate smoothly.
If you want extra flavor, try adding roasted garlic or herbs like thyme or rosemary to the mix before mashing.
For a variation, substitute half of the cheddar cheese with cream cheese for a richer flavor profile.
If you find the consistency a bit thick after mixing, you can add a splash of milk or cream to loosen it up.

There’s something genuinely rewarding about sitting down with a steaming bowl of creamy, cheesy mashed potatoes. Whether you’re sharing it with friends and family or indulging solo, this dish is bound to satisfy your cravings and warm your heart. Don’t hesitate to experiment with flavors or add-ins—every batch can be a little different and even more delightful.
