Betty Crocker's Old-Fashioned Potato Salad Recipe: Buttery Mayonnaise and Mustard Harmony

Betty Crocker's old-fashioned potato salad recipe delivers that perfect balance of creamy mayonnaise and tangy mustard that makes every bite irresistible. 💛 I grew up on this classic version—my grandmother would make it for summer picnics, and it became my go-to for family gatherings.

The secret lies in the harmony of ingredients: waxy potatoes hold their shape, eggs add richness, and a touch of mustard cuts through the richness for that signature tang.

This recipe is all about simplicity and precision—no fancy techniques, just boiling potatoes until tender, mixing them with a luscious dressing, and letting it chill for hours. The result is a potato salad with a velvety texture and a flavor that's both comforting and nostalgic.

It's the kind of dish that feels like a hug in every bite, perfect for potlucks or a casual Sunday lunch.

What makes this version special is how the flavors develop as it sits. The mustard mellows into the creamy base, while the celery and red onion add just the right amount of crunch.

Serve it at room temperature, and you'll have a crowd-pleaser that disappears faster than you can say "second helping." Let's get started on recreating this timeless classic.

Once you try this, you'll understand why it's been a staple for generations. The recipe scales easily for parties, and leftovers keep beautifully in the fridge for up to three days.

Trust me—this is the potato salad that will have everyone asking for the recipe. Here's how to make it perfectly every time.

Ingredients for betty crocker old fashioned potato salad

Six ingredients make this nostalgic potato salad shine—creamy, tangy, and perfect for summer gatherings.

The potatoes are everything. Yukon Golds hold their shape beautifully, but any waxy variety works—red potatoes or fingerlings too. I always buy mine from Whole Foods when they're on sale, but regular grocery stores carry them year-round. Cut them evenly so they cook at the same rate—about 1-inch pieces. The key is boiling them until fork-tender, not mushy. For extra richness, some folks add a splash of milk to the boiling water, but I skip it. The eggs? Room-temperature eggs peel easier after boiling, and they bind the salad perfectly.

No duck egg mayo? Hellmann's or Best Foods work fine—just use the full-fat version. The mustard is non-negotiable for that classic tang, but if you're sensitive to heat, cut it with an extra 1/2 tsp sugar. Fresh dill is ideal, but dried dill at 1/4 the amount gets you close. The red onion can be swapped for green onion if you prefer milder flavor—just use the same amount. For a smoother texture, pulse the celery and onion in a food processor (but don't overdo it—we want some bite!). The butter? Full-fat only—low-fat won't give that velvety finish.

This salad tastes even better the next day as flavors meld. Store leftovers in an airtight container with a damp paper towel over the top to keep it moist—lasts 4-5 days in the fridge. For parties, I double the batch and serve it in a big glass bowl with a ribbon. It reheats surprisingly well if you want to serve it warm (though traditionalists will scoff). The dressing keeps separately for 1 week, so you can make it ahead if needed.

Step-by-step instructions for Betty Crocker's old-fashioned potato salad

Here's how to make the creamy, tangy potato salad Betty Crocker fans love—perfectly balanced every time.

Place the 2.5 lb Yukon Gold Potatoes in a large pot and cover with cold water by about 2 inches. Add 1 tsp salt and bring to a boil over high heat. Once boiling, reduce to medium-high heat and cook for 12-15 minutes until a knife slides in easily.

Drain immediately and transfer the potatoes to a large bowl. Let them cool for 5 minutes before handling. This cooling step prevents the potatoes from breaking apart when quartered. While they cool, I like to give them a gentle shake to help them dry slightly—this makes them less sticky when we add the dressing.

Once cool enough to handle, cut the potatoes into even quarters (about 1-inch pieces). I find using a sharp chef's knife and cutting directly on the cutting board works best. Place the quartered potatoes back in the bowl and let them cool completely to room temperature—this ensures they won't make the dressing watery when mixed.

Here's the thing—if you try to mix warm potatoes with the dressing, you'll end up with a soupy salad. The starch released from warm potatoes breaks down the mayonnaise. Patience here makes all the difference for that perfect creamy texture.

In a medium bowl, whisk together the 1.5 cups Mayonnaise, 0.5 cup Yellow Mustard, 1 tbsp White Vinegar, 1 tsp Sugar, 1.5 tsp Salt, and 0.5 tsp Ground Black Pepper until completely smooth. The sugar and vinegar balance the mustard's tang while the salt and pepper enhance all the flavors.

Melt the 2 tbsp Butter in a small saucepan over low heat until just melted, then let it cool slightly. Stir the melted butter into the mayonnaise mixture. This butter adds incredible richness that makes this salad truly old-fashioned and special. The warm butter should blend seamlessly into the dressing.

Add the cooled, quartered potatoes to the dressing bowl and gently fold everything together using a large spatula. Be careful not to mash the potatoes—we want those beautiful chunks. Fold just until the potatoes are evenly coated with the dressing.

Next, add the 2 whole Celery Stalks (finely diced), 0.5 cup Red Onion (finely diced), and 0.25 cup Fresh Dill (chopped). Gently fold these in last to preserve their texture. Transfer the salad to a serving bowl and cover. Refrigerate for at least 2 hours (I prefer 4 hours) to let all the flavors meld together.

Before serving, give the salad one final gentle fold to redistribute everything. The chilling time allows the flavors to develop beautifully—you'll notice the mustard's tang softens slightly and the dill's freshness really comes through. This salad tastes even better the next day as the flavors continue to meld.

Serve this classic potato salad with crusty bread, grilled chicken, or as a side for your favorite picnic. The perfect balance of creamy, tangy, and fresh makes it a crowd-pleaser every time. Don't forget to taste as you go—adjust seasoning if needed, but this recipe is already perfectly balanced!

Make-ahead tips for this betty crocker old fashioned potato salad

Prep Ahead Like Grandma

My grandmother always made potato salad the night before—she swore it tasted better after sitting overnight. The key is making the dressing first and storing it separately. Combine the mayonnaise, mustard, vinegar, sugar, salt, pepper, and melted butter in an airtight container and refrigerate for up to 1 week.

This way, you only need to boil and cool the potatoes the day of the picnic. 💫

Potato Prep Shortcut

Save time by pre-peeling and quartering the potatoes the night before, storing them in cold water in the fridge. The water keeps them from browning while you prep other dishes.

Drain and dry them thoroughly before mixing with the dressing—this prevents a watery salad. I like to use a colander with a lid to store them overnight.

Make-Ahead Mixing

For ultimate convenience, mix everything except the fresh dill and celery up to 24 hours ahead. Store in an airtight container with a damp paper towel over the top to maintain moisture.

When ready to serve, simply fold in the fresh herbs and vegetables. This works especially well for large gatherings where you want to minimize last-minute work. 🍽️

Freezer-Friendly Dressing

Did you know you can freeze the dressing separately? Portion it into 1-cup freezer bags and freeze for up to 3 months. When ready to use, thaw overnight in the fridge.

Just add the thawed dressing to freshly cooked, cooled potatoes and mix gently. This is perfect for stocking your freezer with picnic staples.

Chilling Time Matters

Never skip the chilling time—this is when the magic happens. The flavors meld together beautifully, and the mustard's sharpness softens into a perfect tang. I always make this salad at least 4 hours ahead of serving.

For parties, I like to prepare it the morning of and keep it in the fridge until serving time. The texture stays perfect and the flavors deepen. ❄️

Portioning for Parties

For large gatherings, divide the salad into quart-sized mason jars or plastic containers with tight-sealing lids. This makes it easy to transport and serve family-style. Store them in the fridge until ready to serve, then simply invert onto a platter.

The layers stay intact, and you can serve directly from the jar if needed. Just add a sprig of fresh dill on top for a pop of color. 🌿
