This sweet peppers potato salad copycat recipe delivers the exact same creamy, herby perfection you crave—just like the beloved brand, but with a home-cooked twist. The secret lies in perfectly boiled potatoes tossed with a tangy, mayonnaise-based dressing that balances sweet peppers and crunchy celery for every bite.
I've tested this recipe dozens of times to ensure the texture is just right: tender potatoes, crisp vegetables, and a dressing that clings without overpowering.
The foundation starts with boiling potatoes until fork-tender (never mushy), then cooling them completely before mixing. While they chill, you'll sauté sweet peppers and onions until just softened, preserving their natural sweetness.
The dressing—made with mayonnaise, sour cream, and a blend of herbs—gets its signature flavor from a touch of mustard and a splash of vinegar, creating that perfect tangy balance. This isn't just potato salad; it's a creamy, copycat masterpiece that stays fresh in the fridge for days.
What sets this apart is the crunchy celery crown—thinly sliced celery tossed in a little vinegar and salt to keep it crisp. The peppers add a subtle sweetness that pairs beautifully with the herby dressing, while the celery provides that satisfying crunch.
Every ingredient plays a role, and the chilling time (at least 2 hours) lets the flavors meld into something truly special. This is the kind of potato salad that disappears faster than you can say "copycat."
Serve it at picnics, potlucks, or family gatherings—it's always a crowd-pleaser. The recipe scales easily, so you can double or triple it without losing quality. For extra flair, garnish with a sprinkle of paprika or fresh parsley before serving.
Let's get started on this restaurant-quality copycat that tastes just like the original.
Ingredients for sweet peppers potato salad copycat
Six ingredients make the creamy base, plus fresh veggies for that signature crunchy crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Cut into 1-inch cubes |
| Sweet Red Bell Peppers 🍅 | 2 whole | Seeds removed, diced small |
| Yellow Onion 🧅 | 1 whole | Thinly sliced, about 1 cup |
| Celery Stalks 🧅 | 3 whole | Thinly sliced for crunch |
| Mayonnaise 🥫 | 1 ½ cups | Best quality, like Hellmann's |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Dijon Mustard 🍯 | 1 tbsp | For tangy kick |
| White Vinegar 💧 | 1 tbsp | For bright acidity |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Sweet Paprika 🌶️ | ¼ tsp | For garnish, optional |
| Olive Oil 🫒 | 1 tbsp | For sautéing peppers |
The potatoes are non-negotiable here—Yukon Golds stay creamy when cooked. Trader Joe's sells them pre-washed, which saves time. Cut them into even cubes so they cook at the same rate. For the peppers, grab the sweet red variety from the produce section—they're sweeter than the green ones. If you can't find fresh dill, dried works at one-third the amount, but fresh is definitely better. I always buy extra dill because it's used in both the dressing and garnish—Costco sells it in big bunches for cheap.
No mayonnaise? Greek yogurt works in a pinch—just add an extra tablespoon of sour cream to keep it creamy. The vinegar and mustard are what give this dressing its signature tang, so don't skip them. For the celery, thin slices stay crisp longer—toss them in a little vinegar right after slicing. The paprika is optional but adds that restaurant-quality finish. If you're making this ahead, cover the celery with plastic wrap to keep it extra crisp. The peppers can be sautéed in butter if you prefer, but olive oil gives a cleaner flavor.
This salad tastes even better the next day—the flavors meld perfectly after chilling 24 hours. Store it in an airtight container with a paper towel on top to absorb any moisture. Keeps 4-5 days in the fridge, though I've never had leftovers that long. For potlucks, I double the batch and pack it in individual containers so everyone gets a taste. The dressing separates if stored too long, so give it a quick stir before serving. Garnish with fresh parsley right before eating—it brightens everything up.
Why You'll Love This Recipe

- Sweet-Savory Magic: That combo of roasted red peppers and sharp yellow onion? It’s like a hug in salad form. The mayo keeps it creamy, but the peppers bring this bright, almost smoky sweetness that makes you want to eat it straight from the bowl.

Step-by-step instructions for sweet peppers and potato salad
This copycat recipe delivers the perfect balance of creamy, tangy dressing and crisp, fresh veggies.
Cook the Potatoes Until Tender
Place the 2.5 lb Yukon Gold Potatoes (cut into 1-inch cubes) in a large pot and cover with cold water by about 1 inch. Add 1 tsp salt and bring to a boil over high heat. Once boiling, reduce heat to medium-high and cook for 12-15 minutes until the potatoes are fork-tender but still hold their shape.
Drain the potatoes thoroughly in a colander, then rinse under cold water to stop the cooking process. This ensures they stay firm and don't turn mushy when mixed with the dressing. Spread them on a clean kitchen towel to dry completely—this step prevents a watery salad later.
Sauté the Sweet Peppers and Onion
Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the thinly sliced yellow onion and cook for 3-4 minutes until softened but not browned. Add the diced sweet red bell peppers and cook for another 5-6 minutes until they begin to soften and release their natural sweetness.
I like to keep the peppers slightly crisp—this adds texture contrast to the creamy salad. If they start to brown too quickly, reduce the heat slightly. Remove the peppers and onion from the skillet and set aside to cool. You'll add them back later when everything comes together.
Mix the Creamy Dressing
In a large mixing bowl, combine the 1.5 cups mayonnaise, 0.5 cup sour cream, 1 tablespoon Dijon mustard, 1 tablespoon white vinegar, 1.5 teaspoons salt, and 0.5 teaspoon black pepper. Whisk until smooth and fully blended. The dressing should be thick but pourable—this is your base for that signature creamy texture.
Here's the thing—don't rush this step. The quality of your dressing makes or breaks the salad. If it looks too thick, add 1-2 teaspoons of water to loosen it slightly. The dressing should coat the back of a spoon but still hold its shape when drizzled.
Combine Everything and Chill
Add the cooked potatoes, sautéed peppers and onion, thinly sliced celery stalks, 0.25 cup chopped fresh dill, and 0.125 cup chopped fresh parsley to the dressing. Gently fold everything together with a large spoon or spatula, being careful not to break up the potatoes too much. You want to maintain some texture in this salad.
Cover the bowl and refrigerate for at least 2 hours (or up to 24 hours) before serving. This chilling time lets the flavors meld together and the potatoes absorb the dressing. The longer it sits, the creamier and more flavorful it becomes—trust the process.
Garnish and Serve
Before serving, give the salad one last gentle stir. Sprinkle with 0.25 teaspoon sweet paprika (if using) for a subtle smoky touch. The paprika adds just a hint of color and warmth that complements the fresh herbs and creamy dressing.
Serve immediately or let it sit at room temperature for 15-20 minutes before serving—this helps the flavors come together even more. The perfect slice should have creamy dressing clinging to each potato cube, with bright peppers, crisp celery, and fresh herbs peeking through.
Pro Tips For Making Sweet Peppers Potato Salad Copycat
- BOIL POTATOES UNTIL TENDER: Don’t cut them until fully cooked—Yukon Golds should pierce easily with a fork, not just slightly soft. I learned this the hard way when my salad turned mushy because I rushed the cooking. Cool them in the pot with cold water for 5 minutes to stop cooking, then drain.
- CHAR THE PEPPERS: Sear the red bell peppers directly over a gas flame (or under a broiler) for 2-3 minutes per side until blackened in spots. This smoky depth is what sets this salad apart—skip the oven, it’s faster and more flavorful. Just brush off the char before chopping.
- DICE ONIONS SMALL: Cut the yellow onion into 1/8-inch pieces, not the usual 1/4-inch. They’ll soften and sweeten more evenly when mixed with the mayo, and you’ll avoid that sharp bite that ruins the balance. Trust me, your taste buds will notice the difference.
- FOLD MAYO IN LAYERS: Start by mixing half the mayo with the warm potatoes, then add the chopped veggies, and finish with the rest of the mayo. This keeps the texture creamy without making the salad greasy—especially important if you’re using full-fat mayo. Stir gently to avoid breaking the potatoes.
Dietary considerations for this sweet peppers potato salad copycat
Gluten-Free Adaptation
This potato salad is naturally gluten-free, but always double-check your ingredients—especially mayonnaise and mustard. Brands like Hellmann's and Duke's offer certified gluten-free options, while Annie's gluten-free Dijon mustard works perfectly. The only potential concern is cross-contamination, so use clean utensils and surfaces if sharing a kitchen with gluten-containing foods. 🌱
Dairy-Free Option
Swap the sour cream for full-fat coconut yogurt (like So Delicious brand) to keep the creamy texture. For mayonnaise, choose a dairy-free version such as Hellmann's Vegan or Just Mayo.
The dressing will still hold together beautifully, though it may be slightly lighter. Garnish with extra fresh herbs to keep it vibrant and flavorful.
Lower-Carb Version
Reduce the potatoes to 1.5 lb and add ½ cup diced cauliflower to the boiling water for extra texture. The cauliflower will soften alongside the potatoes, adding bulk without many carbs.
Keep the sweet peppers and celery amounts the same—they're naturally low-carb and add great flavor. This version still delivers that signature creamy taste but with fewer carbs per serving.
Vegetarian-Friendly
This recipe is already vegetarian, but if you want to make it vegan, replace the mayonnaise with vegan mayo (like Follow Your Heart brand) and use vegan sour cream (like Tofutti).
The flavor remains rich and creamy, perfect for plant-based diets. The sweet peppers and celery add freshness that balances the tangy dressing beautifully. 🌿
Allergy Considerations
For nut allergies, ensure your mayo and mustard are nut-free—many brands list this on their packaging. If you're avoiding eggs (common in some mayos), opt for a vegan mayo or make your own with silken tofu and lemon juice.
Always read labels carefully, as ingredients can vary by brand. When in doubt, homemade dressings give you full control over allergens.

Frequently asked questions
Can I use green bell peppers instead of sweet red?
Green bell peppers work perfectly—they're just slightly less sweet and a bit more bitter. For the best flavor match, use a mix of red and green peppers (1 red to 1 green) to maintain that signature sweetness. If you only have green, add a pinch of sugar to the dressing to balance the flavor.
Why does my potato salad turn watery after mixing?
This usually happens if the potatoes weren't fully cooled before mixing or if they were overcooked. Always rinse boiled potatoes with cold water and pat them completely dry before adding to the dressing. Also, make sure your mayo and sour cream are cold—they'll help thicken the salad as it chills.
How do I keep the celery extra crispy?
Slice the celery just before mixing and immediately toss it with 1 teaspoon vinegar and ¼ teaspoon salt. Store it separately in an airtight container with a paper towel underneath to absorb moisture. Add it to the salad right before serving to maintain that perfect crunch.
Can I make this salad ahead of time?
This salad tastes even better after chilling 24 hours—the flavors meld perfectly. Store it in an airtight container with a paper towel on top to absorb any excess moisture. Keep it refrigerated for up to 5 days, though I've never had leftovers that long!
What's the secret to the creamy texture?
The secret is in the dressing ratio and chilling time. Use high-quality mayonnaise and let the salad sit at least 2 hours before serving. The longer it chills, the more the potatoes absorb the dressing, creating that signature creamy consistency. Also, make sure your sour cream is full-fat for maximum creaminess.
