Full recipe and instructions are provided below.

How to make mashed potatoes
Step 1: Rinse the potatoes and scrub away any dirt. Cut baby potatoes in half (or chop larger potatoes) and place them in a large pot.
Recipe Tip
Any potato variety works. If you use larger potatoes, cut them into smaller pieces so they cook evenly and more quickly. I prefer small potatoes halved for convenience.

Leaving the skins on adds texture and nutrients, but peel if you prefer a smoother result.

How to boil potatoes for mashed potatoes
Step 2: Pour in vegetable broth and enough water to cover the potatoes. Using broth builds more flavor as the potatoes cook.

Bring to a boil over high heat, then simmer until a fork slides easily into the potatoes and they begin to fall apart—typically about 20–30 minutes, depending on size.


Step 3: Drain the potatoes and return them to a bowl. Add butter, sour cream, and milk, then mash to your preferred consistency. Leave a few lumps for texture or mash until completely smooth—both are delicious.


How much salt to add to mashed potatoes
Salt at the end to control seasoning. If you used unsalted butter and no salt in the boiling water, start with about 1 teaspoon and adjust to taste. If you used salted butter or salted the cooking water, add less. Season gradually to avoid over-salting.

These mashed potatoes pair beautifully with gravy and other holiday favorites. They’re creamy, buttery, and have just the right tang from the sour cream—comfort food at its best.
Storing
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, stirring in a splash of milk if needed to restore creaminess.
