How to make Mustard Mashed Potatoes:

The full, printable recipe is at the end of this post. You will need a large pot and a potato masher for this recipe.

Add water and a generous pinch of kosher salt to the pot, and bring the water to a boil. Add the potatoes and cook until very tender. That should take about 25 minutes. Drain the potatoes, and then add them back into the pot.

Add butter to the hot potatoes. The butter should melt quickly. Use a potato masher to mash the potatoes until almost smooth. Alternately, you can use a hand mixer.

Mix in milk and Dijon mustard. Add more milk, as needed, to achieve the texture that you desire for mashed potatoes.

Add more butter and a generous amount of salt and pepper to your potatoes. You’re going to be tempted to eat them before dinner even begins! These potatoes are so delicious. The Dijon mustard gives them a little bit of a tangy flavor that traditional mashed potatoes do not have. I think you’ll enjoy eating them with your favorite meats. Gravy isn’t even necessary, but you can certainly add it. Enjoy!
