What makes this a balsamic potato salad recipe?

In this variation, I decided to use balsamic instead of regular vinegar in this simple potato salad without eggs. Balsamic vinegar adds a sweet and sour taste to anything you add to it which goes beautifully with the smoky mustard flavour from this Smokey BBQ Mustard, vegan mayo, and fresh herbs. I’m also quite fond of having lots of fresh herbs in a potato salad with a cup of I made this one with parsley but I think it would be equally delicious with dill.

Serving this as a warm potato salad or a cold one?

Personally, I prefer serving this as a vegan warm potato salad rather than a cold one. Traditionally, this Smoky Whole Grain Mustard Potato Salad Recipe would be served cold. However, after trying it as a warm potato salad, I’m sold on the warm aspect.

Making a simple potato salad without eggs

If you would like to make this without eggs it will be a more complicated ingredient to substitute. So, to balance out the lack of eggs, you will want to replace it with this delicious smoky flavour found in the mustard. Pair that with the sweetness of the balsamic vinegar and you have yourself a hearty yet flavourful Smoky Whole Grain Mustard Potato Salad recipe.

How to Make a Smoky Whole Grain Mustard Potato Salad Recipe

What I love the most about this recipe is the ease of it. It has few ingredients, it is easily eaten as a vegan warm potato salad, and requires little work and cleaning after.

Start by baking your potatoes. If you are making this recipe from leftover baked potatoes, you can easily skip this step and mix in your ingredients. Preheat the oven at 350˚F (176˚C) and line the baking sheet with parchment paper. If you are using baby or fingerling potatoes simply cut them in half. If your using larger tallow flesh potatoes, I would cut them in quarters at least. Drizzle on salt and olive oil onto the potatoes and give them a good toss to ensure that they are entirely coated with the olive oil. Bake for 20 minutes or until they are a golden-brown color.

While the potatoes are baking, prepare the rest of the ingredients into a medium-sized bowl. When slicing your onions make sure that they are as thinly sliced as possible, there is nothing worse than biting into a big chunk of onion.

Once the potatoes are well browned, let them cool for 10-15 minutes, or until warm to the touch. Then, mix everything into your prepared bowl until all ingredients are well incorporated. Enjoy this Smoky Whole Grain Mustard Potato Salad recipe a little warm but if you prefer having it cold, you could pop it in the fridge for about 30 minutes too.
