America’s Test Kitchen Potato Salad Recipe: TV-Tested Creamy Classic

This potato salad delivers the creamy, classic flavor you expect from America’s Test Kitchen, refined through rigorous testing. The secret lies in the perfect balance of textures and flavors, achieved with a method that ensures every bite is consistent.

I’ve adapted this recipe to maintain that signature richness while keeping the preparation straightforward. The potatoes are cooked just until tender, then dressed while warm to absorb the tangy, creamy dressing that coats each piece evenly.

What sets this apart is the attention to detail—crisp vegetables for contrast, a touch of mustard for depth, and herbs that brighten without overpowering. It’s the kind of dish that elevates any meal from ordinary to memorable.

Serve it at your next gathering and watch it disappear. This is potato salad done right.

Ingredients for America’s Test Kitchen Potato Salad

Classic ingredients balanced for that signature creamy texture and bright, tangy flavor you know and love.

The potatoes are the foundation here. Yukon Golds strike the perfect balance—creamy but hold their shape. Look for firm, smooth skins without sprouting. Whole Foods or a well-stocked produce section will have the best selection. For the dressing, Hellmann’s mayonnaise and full-fat sour cream deliver the richness America’s Test Kitchen is known for. Don’t skip the vinegar; it brightens the whole dish.

Need to swap something? Red potato works in a pinch but can get waxy. No fresh herbs? Dried dill at one-third the amount works—just rehydrate in warm water first. Out of Dijon? Yellow mustard with a pinch of cayenne gets close. The celery is non-negotiable for texture, but if you must, green bell pepper adds similar crunch without the stringy bits.

This holds up well for 2 days in the fridge (the flavors actually improve). Keep it covered tightly—potatoes absorb odors. Freezing’s not ideal (it turns the potatoes mushy), but if you must, 1 month max in an airtight container. Best served slightly cool, not ice cold.

Step-by-Step Instructions for Creamy Potato Salad

This method delivers the perfect balance of creamy texture and bright, tangy flavor every time.

Step 1: Cook and Cool the Potatoes

Place the 2 lb Yukon Gold Potatoes (peeled and cut into ¾-inch cubes) in a large pot and cover with cold water by 1 inch. Add 1 tablespoon kosher salt to the water. Bring to a boil over high heat, then reduce to a simmer and cook for 8-10 minutes until the potatoes are tender when pierced with a fork but not falling apart.

Drain the potatoes immediately and spread them on a rimmed baking sheet. Let them cool completely for 20-30 minutes. This prevents the salad from becoming gummy when mixed with the dressing. The potatoes should be room temperature and slightly dry to the touch before proceeding.

Step 2: Prepare the Vegetables and Herbs

While the potatoes cool, finely dice the 2 whole Celery stalks and ½ whole Red Onion. Soak the diced red onion in cold water for 10 minutes to mellow its sharpness, then drain well. Chop the ¼ cup Fresh Dill and 2 tbsp Fresh Parsley into fine pieces.

Peel and chop the 4 whole Hard-Boiled Eggs into ¼-inch pieces. I find that pressing the eggs through a wire mesh strainer creates perfectly even pieces without tearing. Pat all the vegetables dry with a paper towel to remove excess moisture that could thin the dressing.

Step 3: Make the Creamy Dressing

In a large bowl, whisk together the ¾ cup Mayonnaise, ¼ cup Sour Cream, 2 tbsp Dijon Mustard, 1 tbsp White Vinegar, 1½ tsp Kosher Salt, and ½ tsp Black Pepper until smooth. The vinegar will help balance the richness of the mayonnaise and sour cream.

Stir in the 2 tbsp Sweet Pickle Relish until evenly distributed. Taste and adjust seasoning if needed—the dressing should be tangy with a subtle sweetness. This base will coat the potatoes and vegetables perfectly without being overly heavy.

Step 4: Combine and Chill for Optimal Flavor

Add the cooled potatoes to the bowl with the dressing. Gently fold everything together with a rubber spatula until the potatoes are evenly coated. Avoid overmixing to keep the potatoes intact. Add the celery, red onion, dill, parsley, and eggs, folding gently to distribute.

Cover the bowl with plastic wrap and refrigerate for at least 1 hour (or up to 24 hours). This chilling time allows the flavors to meld and the dressing to fully absorb into the potatoes. The salad is ready when it’s thoroughly chilled and the flavors have deepened into that classic, creamy taste.

Dietary Considerations for This americas test kitchen potato salad

Gluten-Free Friendly

This creation is naturally gluten-free, making it perfect for anyone avoiding wheat. All ingredients—from Yukon Gold Potatoes to Hellmann’s mayonnaise—are safe for gluten-sensitive diets. Just double-check your Dijon mustard and pickle relish labels, as some brands add thickeners. 💡

Vegetarian Adaptation

The recipe is already vegetarian as written. For a vegan version, swap the hard-boiled eggs for ½ cup diced avocado and use vegan mayo and dairy-free sour cream. The creamy texture remains intact, and the avocado adds a nice richness.

Dairy-Free Option

To make this dairy-free, replace the ¼ cup sour cream with an equal amount of dairy-free yogurt or additional mayonnaise. The dressing will still cling beautifully to the potatoes, and the tangy flavor stays balanced.

Egg-Free Version

Simply omit the 4 hard-boiled eggs if needed. The salad stays creamy and satisfying without them. For extra protein, consider adding ½ cup diced cooked chicken or chickpeas to keep it hearty.

Lower-Calorie Swap

For a lighter take, use light mayonnaise and low-fat sour cream to cut calories without sacrificing flavor. You can also reduce the dressing by ¼ cup—the potatoes will still absorb the flavors beautifully. 💪

Allergen Note

This dish contains eggs and dairy (sour cream), so it’s not suitable for those with egg or dairy allergies. Always verify ingredient labels to ensure no cross-contamination risks.
