Ingredients

• 5 pounds russet or Yukon Gold potatoes, peeled and cubed (about 1-inch pieces)
• 1 cup mayonnaise (full-fat recommended)
• 1/2 cup yellow mustard
• 1/4 cup sweet pickle relish
• 1/4 cup apple cider vinegar
• 1/4 cup granulated sugar
• 1 tablespoon kosher salt, plus more for boiling water
• 1 teaspoon black pepper
• 1 large stalk of celery, finely chopped
• 1/2 medium red onion, finely chopped
• 2 large eggs, hard-boiled and chopped (optional, but traditional)

Step-by-Step Instructions

1. Prepare the potatoes: Place the peeled and cubed potatoes in a very large pot. Cover generously with cold water and add about 1 tablespoon of salt. Bring the water to a boil over high heat.
2. Cook the potatoes: Boil the potatoes until they are fork-tender but not mushy (approximately 10-15 minutes, depending on the size of the cubes). Be careful not to overcook them, as they need to hold their shape.
3. Drain and cool: Drain the potatoes immediately in a colander. Allow them to cool for about 15 to 20 minutes. While still slightly warm, gently transfer the drained potatoes to a very large mixing bowl.
4. Create the dressing: In a separate medium bowl, whisk together the mayonnaise, yellow mustard, sweet pickle relish, apple cider vinegar, granulated sugar, 1 tablespoon of kosher salt, and black pepper until smooth and well combined.
5. Add mix-ins: To the slightly cooled potatoes, add the finely chopped celery and red onion, along with the chopped hard-boiled eggs, if using.
6. Combine carefully: Pour about two-thirds of the prepared dressing over the potatoes and vegetables. Gently fold the mixture together using a large rubber spatula. The key here is to mix gently to avoid breaking up the potatoes too much.
7. Adjust seasoning and chill: Taste the salad. If needed, add more of the remaining dressing until you reach your desired creaminess. Adjust salt or vinegar to taste. Cover the bowl tightly with plastic wrap and refrigerate for at least 4 hours, but preferably overnight, to allow the flavors to fully meld.

Expert Tips / Pro Tips

To achieve truly authentic Rudy’s Country Store Potato Salad flavor, pay attention to these details:

• Use the Right Vinegar: Apple cider vinegar is crucial for the specific tanginess found in the original. Do not substitute with white vinegar as it lacks the necessary depth.
• Potato Choice Matters: Russet potatoes work well because they are starchy and absorb the dressing beautifully, but Yukon Golds offer a creamier texture that many prefer. Avoid waxy red potatoes if you want the classic texture.
• Dress While Warm: Draining the potatoes while still warm allows them to soak up the vinegary dressing much better than fully cold potatoes, intensifying the flavor base before the mayonnaise is added.
• Chill Time is Non-Negotiable: This salad tastes significantly better on the second day. The chilling period allows the sugar and vinegar to marry, resulting in that addictive sweet-and-sour profile.

Variations & Substitutions

While staying true to the original flavor profile, feel free to customize slightly:

• Spice it Up: For a slight kick, substitute a teaspoon of Dijon mustard for a portion of the yellow mustard, or add a dash of your favorite hot sauce to the dressing base.
• Onion Swap: If red onion is too sharp, you can use green onions (scallions) for a milder flavor.
• Herb Addition: Fresh dill or chives can be added during the chilling phase for a slight herbal freshness, though this is not traditionally included in the standard recipe.
• Use Less Mayo: If you prefer a lighter salad, reduce the mayonnaise by 1/4 cup and slightly increase the apple cider vinegar (add 1 tablespoon more).

Serving Suggestions

This potato salad is an essential part of any barbecue spread. Serve it alongside classic Texas smoked meats like slow-smoked brisket, pulled pork, or smoked sausage. It pairs wonderfully with grilled chicken, ribs, and even hamburgers or hot dogs. For a full picnic feel, serve chilled alongside coleslaw and baked beans.

Storage, Freezing & Reheating

Storage: Due to the mayonnaise content, this potato salad must be stored properly in an airtight container in the refrigerator. It is best consumed within 4 to 5 days. Always ensure it remains chilled, especially when serving outdoors.

Freezing: Due to the high moisture content from the mayonnaise and vinegar, freezing this potato salad is generally not recommended. The dressing may separate and become watery upon thawing.

Reheating: Potato salad is meant to be served cold. Do not attempt to reheat it. If it has been sitting out at room temperature for more than two hours, it should be discarded for safety reasons.

Nutritional information is approximate and based on serving size defined as 1/8th of the recipe (approximately 3/4 cup serving) and includes the optional eggs.

FAQ

Why is my potato salad mushy?

Your potato salad is likely mushy because the potatoes were overcooked or stirred too vigorously after the dressing was added. For the best texture, aim for fork-tender potatoes and use a light folding motion when mixing everything together.

Can I make this Rudy’s Country Store Potato Salad ahead of time?

Yes, absolutely. In fact, making it ahead of time is highly recommended. For the best flavor, prepare it at least 4 hours in advance, or ideally, the day before you plan to serve it, allowing ample time for the flavors to meld.

What type of mustard gives the best flavor?

Classic yellow mustard is essential for achieving the authentic flavor profile associated with this style of barbecue potato salad. Do not substitute it with spicy brown or whole grain mustard unless you are intentionally trying to alter the traditional taste.

Ingredients

  

For the Salad

• 3 lbs Yukon Gold Potatoes Waxy potatoes work best; scrubbed and quartered
• 4 large Eggs hard-boiled and chopped
• 1 cup Celery finely chopped
• 1/2 cup Red Onion very finely minced
• 2 Tbsp Fresh Dill chopped
• 1/2 tsp Celery Seed

For the Dressing

• 1 1/2 cups Mayonnaise Full fat recommended
• 1/4 cup Yellow Mustard
• 3 Tbsp Sweet Pickle Relish
• 2 Tbsp Apple Cider Vinegar
• 1 tsp Sugar
• to taste Salt and Black Pepper

Method

 

Instructions

1. Place the quartered potatoes in a large pot and cover them with cold, salted water. Bring to a boil and cook for 15-20 minutes, or until fork-tender but not mushy. Drain immediately and let cool slightly.
2. While potatoes are cooking, prepare the hard-boiled eggs. Peel and coarsely chop them once cool enough to handle. Set aside.
3. In a large mixing bowl, whisk together all the dressing ingredients: mayonnaise, yellow mustard, sweet pickle relish, apple cider vinegar, sugar, salt, and pepper until completely smooth and well combined.
4. Gently fold the warm potatoes into the dressing. The warmth helps the potatoes absorb the flavor. Add the chopped celery, red onion, chopped eggs, fresh dill, and celery seed. Mix very gently to avoid breaking up the potatoes entirely.
5. Taste the salad and adjust seasonings (more salt, pepper, or vinegar if needed for tanginess). Cover the bowl tightly with plastic wrap.
6. Refrigerate the potato salad for a minimum of 4 hours, or preferably overnight, to allow the flavors to fully meld and develop. Serve chilled.

Notes

For the best texture, do not overcook the potatoes. Yukon Golds or Red Bliss are the best varieties for holding their shape. If making ahead, reserve a tablespoon of vinegar to stir in just before serving to brighten the flavor.
