Ingredients for Whole Grain Mustard Mashed Potatoes

- 1/2 cup butter

- 1/4 cup whole grain Dijon mustard
- salt and pepper
How to Make Whole Grain Mustard Mashed Potatoes
STEP ONE: Place the potatoes in a large pot and add enough water to cover by about 1 inch.
STEP TWO: Bring to a boil over high heat, then reduce to medium and cook until fork-tender, about 12–15 minutes. Drain and return the potatoes to the pot.
STEP THREE: Add butter, oat milk, mustard, salt, and pepper, and mash to your desired consistency. Adjust seasoning to taste and serve hot.
FAQ
- Can I use a different type of potato? Yes, but Yukon Gold potatoes are ideal for their creamy texture. Russet potatoes or red potatoes can also work, though they may have a slightly different texture.
- What’s the best substitute for oat milk? Unsweetened almond milk or soy milk work well as non-dairy substitutes.
- Can I make this ahead of time? Yes, you can prepare the mashed potatoes in advance. Store them in an airtight container and reheat with a bit of added milk or butter to restore creaminess.
- How much mustard should I add for a stronger flavor? For a bolder mustard taste, start with an extra teaspoon and adjust from there, tasting as you go.
- Can I use smooth Dijon mustard instead of whole grain? Absolutely! Smooth Dijon will still add that tangy kick, though whole-grain gives a bit of extra texture.

What a genius idea to add mustard to mashed potatoes! I get bored of gravy. I made this to pair with your twice baked BBQ tofu bites like you suggested. I left out the butter and added a little more milk. So good!
