How to make mashed potatoes

Step 1: Rinse the potatoes and scrub off any dirt. Cut the baby potatoes in half, then place in a large pot.

Note: Any potatoes will do, but you may need to cut them up smaller to allow for faster cook time. I like using smaller potatoes for this reason, as I just cut them in half.

I prefer to leave the skins on for my mashed potatoes, but if you do not like skins, you can peel the potatoes before boiling.

Step 2: Pour in the vegetable broth and enough water to make sure the potatoes are covered in liquid. I like using vegetable broth to add more flavor to the potatoes while they cook.

Turn the burner on high and bring the potatoes to a boil. Boil until a fork easily pierces the potatoes and they fall apart.

This time will vary based on the size of the potatoes boiled, for me it took around 20 – 30 minutes.

Step 3: Once your potatoes are soft and easily pierced with a fork, drain them. Mash the potatoes, and add the butter, sour cream, and milk. Mash until desired texture is achieved. You can either leave a few lumps, or mash until smooth. It’s personal preference.

How much salt to add to mashed potatoes

Salting should always be the last step when making mashed potatoes. For this recipe, I did not salt the potatoes while boiling, and used unsalted butter.

I ended up using only around 1 teaspoon of salt mixed in at the end to make them perfect.

I suggest adding salt and pepper to taste a little bit at a time to avoid over salting your mashed potatoes. If you use salted butter or salt your potatoes while boiling, you will need less salt.

We always serve these mashed potatoes alongside the best vegetarian gravy. It’s truly the best gravy I have ever tasted! And it’s a must have along with sweet potato casserole, cheesy potatoes, and stuffing.

These sour cream mashed potatoes are the most heavenly comfort food – creamy, buttery, and the perfect flavor!

Make these for your Thanksgiving table this year.
