Step‑by‑Step Instructions for Mustard Potato Salad
Step 1: Cook Potatoes
Begin by placing the peeled russet potatoes in a large pot, covering them with about 1 inch of water. Bring the water to a rolling boil over high heat, then reduce the heat to medium-low, cover the pot, and simmer for 25–30 minutes. The potatoes should be tender when pierced with a fork, but still firm. Once done, drain the water and allow the potatoes to cool completely.
Step 2: Cube Potatoes
Once cooled, carefully cut the potatoes into bite-sized cubes that will blend perfectly into your creamy mustard potato salad. Each piece should be uniform in size to ensure consistent texture in every bite. Set the cubed potatoes aside as you prepare the dressing.
Step 3: Prepare Dressing
In a large mixing bowl, combine Miracle Whip, sweet relish, yellow mustard, salt, and black pepper. Stir vigorously until all the ingredients are well mixed and the dressing appears smooth and creamy. This flavorful mixture will provide the tangy base for your delicious Mustard Potato Salad.
Step 4: Combine Ingredients
Gently fold the cubed potatoes, chopped hard-boiled eggs, diced celery, sliced green onions, and yellow onion into the bowl with the dressing. Use a spatula to carefully mix everything without mashing the potatoes. Ensure all the components are evenly coated with the creamy dressing for optimal flavor throughout the salad.
Step 5: Chill
Once mixed, cover the bowl tightly with plastic wrap or a lid and place it in the refrigerator. Let the mustard potato salad chill for at least 4 hours, allowing the flavors to meld and deepen. This resting period enhances the overall taste, making each bite even more delicious when you’re ready to serve.

Tips for the Best Mustard Potato Salad
-
Uniform Chunks: Cut potatoes into even-sized cubes to ensure they cook evenly and provide a consistent texture in your mustard potato salad.
-
Cool Completely: After cooking, let the potatoes cool completely before mixing with the dressing. This prevents a runny salad and ensures a creamy consistency.
-
Don’t Overcook: Be careful not to overcook the potatoes; they should be tender but firm. Overcooked potatoes can become mushy and lose their structure.
-
Chilling is Key: Allow the potato salad to chill for at least 4 hours. This time helps the flavors combine beautifully, enhancing that tangy and creamy goodness.
-
Season Well: Always taste and adjust seasoning before serving. A little extra salt and pepper can elevate the overall flavor of your mustard potato salad, making it truly irresistible.
How to Store and Freeze Mustard Potato Salad
Refrigerator: Store leftover mustard potato salad in an airtight container in the fridge for up to 3 days. This ensures it retains its creamy texture and flavor.
Freezer: For longer storage, freeze the potato salad in a freezer-safe container for up to 2 months. Note that the texture might vary upon thawing, so only freeze if necessary.
Thawing: When ready to enjoy, thaw the frozen mustard potato salad in the refrigerator overnight. Avoid microwave thawing to maintain its creamy consistency.
Reheating: If desired, gently mix and serve the salad cold or at room temperature. Reheating is not recommended as it may alter the texture and flavor profile.
Make Ahead Options
These Mustard Potato Salad are perfect for busy weeknights and meal prep enthusiasts! You can prepare the dressing and cubed potatoes up to 24 hours in advance; simply store them separately in airtight containers in the refrigerator to maintain freshness and prevent the potatoes from becoming mushy. Additionally, chop your celery and onions a day ahead as well. When ready to serve, gently combine all the ingredients, fold them together, and let the salad chill for at least 4 hours (or overnight) before serving. This way, you’ll enjoy a delicious, creamy potato salad that’s just as flavorful and satisfying, saving you precious time on a hectic day!

Mustard Potato Salad Recipe FAQs
How do I choose the right potatoes for my salad?
Absolutely! For the best mustard potato salad, I recommend using Russet potatoes. They provide a great fluffy texture and can hold their shape well when cooked. Make sure they are cleaned and peeled for the best consistency. If you prefer a waxy texture, Yukon Golds are also a fabulous option!
What is the best way to store leftover potato salad?
Once you’ve made your delicious mustard potato salad, store any leftovers in an airtight container in the refrigerator. It can last for up to 3 days, keeping its creamy texture and tangy flavor intact. Just ensure the container is sealed tightly to prevent any unwanted odors from seeping in!
Can I freeze mustard potato salad?
While you can freeze mustard potato salad in a freezer-safe container for up to 2 months, I often suggest against it if possible. The texture may change after freezing and thawing, leading to a slightly grainy salad. If you must, make sure to thaw it slowly in the refrigerator overnight, and avoid reheating, as it may further alter the delightful creaminess you desire.
What can I do if my potato salad turns out too runny?
Very good question! If you encounter a runny mustard potato salad, it’s likely that the potatoes haven’t cooled completely before mixing, or too much dressing was added. To remedy this, you can try adding more chopped potatoes to absorb some excess dressing. Another option is to mix in a bit of cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water) to help thicken it up without affecting the flavor.
Is there a way to make this salad suitable for a gluten-free diet?
Certainly! The ingredients in your mustard potato salad are naturally gluten-free, but always double-check your labels on items like Miracle Whip or mustard to be sure there are no hidden gluten-containing ingredients. If you’re considering adding any extras (like pickles or relishes), ensure they are gluten-free as well.
Can pets eat mustard potato salad?
It’s best to keep mustard potato salad away from pets. Ingredients like onions and certain spices can be harmful to dogs and cats. If you want to share some potato with your furry friends, make sure it’s plain, boiled potatoes without any dressings or seasonings.
