Potato Salad

Potato salad can be made in a variety of ways. All potato salads have a base of potatoes, and most contain celery. Hard boiled eggs are often added to the potato salad, along with a dressing and a mixture of seasonings. 

Other ingredients sometimes found in potato salad include celery, onion, peppers, cheese, garlic, and pickles. The sauce in potato salad is typically a mayonnaise-based sauce. Sometimes the sauce will include mustard, sour cream, vinegar, sugar, or salt. Today we are going to look specifically at Costco’s potato salad, and later give you a recipe that is even better than the potato salad you can buy at the store! 


Costco’s potato salad has a bit of a mushy texture to it. The salad has a sauce that is primarily made with mayonnaise and contains a hit of mustard. Their salad also contains a bit of dill seasoning. While many people enjoy the convenience of purchasing potato salad, many people often prefer the taste of the homemade salad. There is just something about making it at home that allows it to taste so much better.

Potato Salad from Costco – yeah or nay?

If you are unsure about buying potato salad from the store, for fear it won’t be good, I would highly encourage you to try making your own potato salad.

Making potato salad from scratch really is that simple.

Drain your potatoes and rinse with ice-cold water until your potatoes are cooled off. 

In a skillet, add oil and precooked bacon. Add in onion and cook stirring occasionally until onions are tender. Stir in water, vinegar, and sugar. Bring to a boil over high heat.

¼ cup onion, finely chopped (optional)
¾ cup mayonnaise
4 slices cooked bacon, crumbled
Salt and ground black pepper to taste


In a large pot, add potatoes and cover with water. Bring to a boil and simmer for 10-15 minutes until potatoes are tender all the way through. Drain and rinse with ice-cold water until potatoes are cool. Set potatoes aside until cooled off. In a mixing bowl, combine, celery, onion, mayonnaise, bacon, salt, and pepper. Cube cooled potatoes and then add into the mixing bowl. Gently toss until everything is coated and mixed completely. Chill, then serve and enjoy! 

Traditional Potato Salad

No matter the time of year, potato salad was always present at all family gatherings for us. My Grandma would come with her huge yellow bowl full of potato salad, and it would be gone by the end of the gathering. She would make traditional potato salad, which contained peeled and cubed potatoes, hard boiled eggs, celery, mayonnaise, mustard, salt, pepper, and sugar. It was a hit amongst our family gatherings for Christmas, Thanksgiving, Easter, and summer get togethers. 

Red Skin Potato Salad

Using red skinned potatoes in potato salad, adds an extra pop of color, and cuts back on the work of pealing all your potatoes. If you used red skins, you could simply leave the peelings right on the potatoes and just dice them up. This is my preferred way of making salad, and red skins just taste so good.

Copycat Costco Potato Salad


Serves: 8 people
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes


2 lbs red skinned potatoes
3 stalks celery, finely chopped
6 hard-boiled eggs
2 green onions, finely chopped
1 cup mayonnaise
½ cup sour cream
1 Tbsp lemon juice
¼ cup bacon bits
Salt and pepper to taste
Parsley, as desired


If desired you may boil your potatoes and eggs ahead of time, allow them to cool, and store them in the fridge so that they are completely chilled before making the salad. Often allowing your potatoes and eggs time to chill will give you the best result and keep them from getting mushy as you stir. 


In a large pot add your potatoes and cover with water. Place them over your burner and cook on high until they begin to boil. Then turn the heat down to medium-low and allow to simmer for 10-15 minutes. Once the potatoes are cooked, you should be able to easily insert a knife or fork into the center. Drain, and run under ice cold water, to cool potatoes. 

In another large pan, add your eggs and cover in water. Bring to a boil and allow them to simmer for 15 minutes at a rolling boil. Remove from heat and drain water. Run under ice-cold water to cool the eggs off. Remove shells and allow to cool. 

After your potatoes and hard-boiled eggs are chilling, in a mixing bowl combine celery, mayonnaise, sour cream, lemon juice, bacon bits. Mix until combined. 

Once potatoes are chilled, cut them into cubes and add them into your bowl with sauce. Also cube chilled eggs and add to mixture. Add green onions and stir until everything is coated. Top with parsley if desired, add salt and pepper to taste. Serve chilled and enjoy! 


This recipe works best when served chilled. If desired, you can also experiment with adding a bit of mustard to taste but leave out the sour cream if you try this. You can also try adding cheddar cheese to your mayonnaise and sour cream mixture if desired. It is difficult to go wrong with this delicious combination.
