This tangy Southern Mustard Potato Salad recipe is exactly what to expect when dining at any Southern home or "home-cookin'" restaurant. You'll love the creamy, slightly tangy flavor and texture!
The best version I've ever had was my Grandmother's recipe. Naturally, she didn't measure any ingredients, but just "eyeballed" the correct proportion of each ingredient and it always came out perfect!
Why you'll love this recipe!
- Quick and easy - Cook and cool the potatoes in advance, then, dice them, add the sauce and you're done!
- Pairs well with ham, barbecue or as a side-dish to a sandwich
- Delicious flavor with a nice texture- not too mushy-just right
- All-natural- no additives, preservatives or weird ingredients
Some Southern cooks put boiled eggs in their mustard Potato Salad; feel free to add a few if you like!
Here's what you'll need:
Typical ingredients for this dish are: russet (or Idaho) potatoes, diced onion, celery, and green bell pepper.
The creamy-tangy dressing consists of: mustard, mayonnaise, a hint of celery salt, oil and white vinegar; some cooks add a few teaspoons of sweet (or dill) relish and/or a boiled egg.
How to make it:
This is pretty quick and easy to make! Boil, cool and cube potatoes. Add chopped onion, bell pepper and celery. Make the sauce in a separate bowl. Fold sauce into potato mixture; season and serve!
The texture of your mustard potato salad depends upon you...I like mine somewhat chunky, so I mash the potatoes just a little, but still leave some nice size chunks in there...your call.
What type of potato?
The secret to this delicious Southern mustard potato salad is to use the right kind of potatoes and let them cool before you dice them--cooling ensures they don't turn into mashed potatoes.
I recommend the big brown russet for the best results. They retain their shape and absorb the flavors better than their waxy cousins, namely Yukon Gold and Red Boiling or Red Creamers.
Make in advance
- Make this "favorite side dish of the South" in advance if you want! Since it contains egg-based mayonnaise, you'll want to make sure it's stored in a secure container in the fridge for no more than 3 days.
- Another option is to boil the potatoes and make the dressing--store both in the fridge. When it's time to serve, slice and cube potatoes, add sauce and serve!
Can I freeze leftovers?
Unfortunately, mayonnaise does not freeze well...the eggs and oil separate and it turns to mush. Plus that, fresh tastes best!
