Ingredients for campbell's party potatoes
Six simple ingredients transform canned potatoes into a showstopping side everyone will ask for seconds of.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Party Potatoes 🥔 | 2 cans | 29 oz each, drained well |
| Mayonnaise 🥛 | ½ cup | Regular or vegan for plant-based |
| Prepared Yellow Mustard 🍯 | ½ cup | Kraft or similar brand |
| Shredded Cheddar Cheese 🧀 | 1 cup | Sharp cheddar preferred |
| Butter 🧈 | ½ cup | Melted, unsalted preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | Adds depth to flavor |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Green Onions 🧅 | 3 whole | Sliced for garnish |
| Nutritional Yeast 🍄 | ½ cup | Vegan cheese substitute |
| Plant-Based Mayo 🥛 | ½ cup | For vegan option |
The Campbell's Party Potatoes are the star, and you want the 29 oz cans—they're the right size for this recipe. I always grab the Kraft yellow mustard from the middle shelf, not the fancy gourmet kind. For the cheese, sharp cheddar makes all the difference—it melts better and has more flavor. If you're doing a vegan version, Bob's Red Mill nutritional yeast is my go-to for that cheesy tang. The mayo? Any brand works, but Hellmann's or Duke's are reliable. Pro tip: check the canned potatoes for any added salt—you might not need to add extra.
No yellow mustard? Dijon mustard at half the amount works in a pinch, but it'll be tangier. Short on cheddar? Parmesan or mozzarella can stretch it out, but the flavor won't be the same. The vegan mayo swap is easy—just use vegan mayo like Just Mayo and double-check the nutritional yeast is fresh (it loses potency over time). For extra flavor, I sometimes add a dash of smoked paprika to the mayo mix, but it's optional. And if you're really in a hurry, you can skip the green onions—they're just for looks, not flavor.
These keep surprisingly well. Store leftovers in an airtight container for up to 3 days—they reheat beautifully in the microwave with a splash of water. For parties, I like to make these 2 days ahead and reheat before serving. The flavor actually improves overnight as everything melds together. If you're prepping for a crowd, double the recipe—it scales perfectly. Just make sure to cover them with foil while reheating to keep everything creamy.

Step-by-step instructions for campbell's party potatoes
This one-pan dish comes together faster than you can say "party time" and delivers big flavor with minimal effort.
Mix the Mustard Mayo Magic
In a medium bowl, combine the 0.5 cup mayonnaise, 0.5 cup prepared yellow mustard, 0.5 cup melted butter, 1 teaspoon garlic powder, 1 teaspoon onion powder, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. If making the vegan version, replace the mayonnaise with 0.5 cup plant-based mayo and add 0.5 cup nutritional yeast for that cheesy kick. Stir until completely smooth and creamy—this is your flavor base.
Here's the thing—this mixture needs to be perfectly blended. Any lumps will show up in your final dish. If you're using regular mayo, I recommend using a hand mixer for 30 seconds to ensure everything's silky smooth. For the vegan version, let the nutritional yeast sit in the mayo mixture for 5 minutes before mixing to help it fully integrate.
Prepare the Potatoes
Open both cans of Campbell's Party Potatoes and drain them thoroughly in a colander, shaking gently to remove excess liquid. Transfer the potatoes to a large mixing bowl and add the 1 cup shredded cheddar cheese. Pour the mustard mayo mixture over the potatoes and gently fold everything together with a spatula until the cheese is evenly distributed and the potatoes are fully coated.
Don't overmix—just enough to combine. You want the potatoes to stay whole and intact, not broken into small pieces. The cheese should melt into the mixture as it bakes, creating that perfect creamy texture. If you notice any dry spots, add a few teaspoons of water to help the sauce cling to the potatoes.
Assemble and Bake to Perfection
Transfer the potato mixture to a greased 9x13-inch baking dish and spread it out evenly. Slice the 3 whole green onions into thin rings and sprinkle them evenly over the top. This adds a fresh pop of color and flavor that elevates the whole dish.
Bake at 375°F for 30-35 minutes until the top is golden brown and bubbly. The edges should be slightly crispy, and the cheese should be fully melted with no raw spots. If you're serving this for a party, you can keep it warm in the oven while you finish other dishes—just cover it loosely with foil to prevent over-browning.
Rest and Serve with Confidence
Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting time allows the flavors to meld together and makes it easier to scoop out perfect portions. The potatoes will be hot and creamy, with that perfect mustard-mayo sauce clinging to every bite.
Serve immediately with your favorite dipping sauces or as a standalone dish that's sure to disappear quickly. This recipe is perfect for game day, potlucks, or any gathering where you want to impress without spending hours in the kitchen. Trust me, your guests will think you slaved away for hours—when in reality, this dish comes together in under 45 minutes!
Pro Tips For Making Campbell'S Party Potatoes
- MIX THE DRESSING FIRST: Don’t wait until the end—whisk together mayo, mustard, and a splash of milk (if the recipe calls for it) while the potatoes bake. The dressing thickens as it sits, and you’ll avoid that awkward moment where everything’s done but the sauce is still runny. I used to rush this, and the result was always gloppy. Five minutes upfront saves cleanup later.
- DON’T OVERMIX THE CHEESE: Fold the shredded cheddar into the hot potatoes just until combined—lumpy is fine. Overworking it turns the cheese into a paste, and you lose that gooey, melty texture everyone loves. My first batch looked like a sad, uniform blob. Stir until it’s mostly even, then let the residual heat do the work.
- BAKE UNTIL GOLDEN, NOT JUST SOFT: The recipe says "baked," but don’t stop when the potatoes are tender. Push it another 5–7 minutes until the edges are golden brown—that’s when the starch turns to flavor. I learned this after a batch tasted bland and pasty. A toothpick test works, but so does trusting your nose: that toasty aroma means it’s ready.
- USE SOFTENED BUTTER, NOT MELTED: The recipe might say "melted butter," but I’ve found room-temperature butter (softened, not liquid) blends better into the potatoes and doesn’t make the dish greasy. It also helps the cheese cling instead of sliding off. Yes, it’s a tiny detail, but it makes the texture richer—trust me, I’ve tested both ways.
Best sauces and condiments for these flavors
Mustard Mayo Magic
The star of this dish is that tangy-sweet mustard mayo sauce—equal parts mayo and prepared mustard create the perfect balance. I always use Kraft yellow mustard because it's consistent and affordable, but Dijon at half the amount works in a pinch if that's all you have.
The secret is blending it with melted butter and spices until completely smooth—no lumps allowed! For extra depth, I sometimes add a pinch of smoked paprika to the mayo mix. 🍯
Cheesy Variations
Sharp cheddar is my go-to cheese, but you can get creative here. For a Mexican-inspired twist, swap in Monterey Jack and add ½ tsp cumin to the mayo. Need a vegan option? Bob's Red Mill nutritional yeast gives that cheesy tang without dairy.
Just remember—cheese melts differently, so adjust baking time if needed. The vegan version needs an extra 5 minutes to get fully crispy on top.
Herb Garnishes
Fresh herbs take this dish to the next level. I love sprinkling chopped chives or green onions on top right before serving—they add a bright, fresh contrast to the rich mustard flavor. For a more robust herb profile, try dried parsley flakes mixed into the mayo before baking.
If you're growing your own herbs like I do in my Portland garden, fresh basil or dill work beautifully too. Just add them after baking to preserve their color and flavor. 🌿
Spicy Kick Options
Want to add some heat? A sprinkle of crushed red pepper flakes mixed into the mayo gives a subtle kick, while ½ tsp cayenne pepper adds serious fire. For a smoky-spicy version, I sometimes stir 1 tbsp chipotle in adobo sauce into the mayo mixture.
If you're serving this to kids, keep the heat mild—just a pinch of flakes on top is plenty. The smoky chipotle version pairs perfectly with grilled meats like pulled pork or steak. 🌶️
Dipping Sauces
Serve these potatoes with complementary dipping sauces to let everyone customize their bites. A simple ketchup mix (equal parts ketchup and mayo) works wonders, or try a spicy mayo by mixing mayo with 1 tsp hot sauce and a pinch of garlic powder.
For something lighter, a sour cream and chive dip with ¼ cup sour cream, 1 tbsp chopped chives, and a squeeze of lemon brightens the whole plate.
I keep these sauces in small bowls on the table so guests can add as much or as little as they like.
Make-Ahead Magic
This dish actually tastes better the next day! Make it 2 days ahead and store in an airtight container in the fridge. When ready to serve, reheat covered at 350°F for 15-20 minutes** until bubbly.
For parties, I like to assemble the dish in the morning and bake it just before guests arrive—this way, it's piping hot and looks freshly made. The flavors meld beautifully overnight, making it perfect for meal prep.
Just add a sprinkle of fresh herbs before serving to keep it looking fresh. ⏰

Frequently asked questions
Can I make this recipe without cheese?
The cheese adds that signature creamy texture and flavor, but you can absolutely skip it! Just omit the 1 cup cheddar and add 2 extra tablespoons of the mustard mayo mixture to compensate. For a vegan version, replace the cheese with ½ cup nutritional yeast mixed into the mayo. The dish will still be delicious—just slightly lighter in texture.
How do I keep these potatoes from getting soggy?
Sogginess happens when too much moisture gets trapped. Always drain the canned potatoes thoroughly before mixing, and pat them dry with a paper towel if needed. Bake uncovered for the last 5 minutes to crisp the top, and avoid overmixing the sauce. For extra insurance, sprinkle a pinch of cornstarch over the top before baking.
Can I use this recipe for a vegan gathering?
Swap the mayo for vegan mayo, use nutritional yeast instead of cheese, and check that your mustard is plant-based. The flavor stays rich and tangy—just add an extra 5 minutes to baking time for a fully crispy top. I've served this at vegan potlucks, and no one ever guesses it's plant-based!
What's the best way to reheat leftovers?
Leftovers reheat beautifully! Cover with foil and warm at 350°F for 15-20 minutes until bubbly. For a crispy top, uncover for the last 2 minutes of reheating. Microwave reheating works too—just add 1 tablespoon water to the dish and cover with a damp paper towel for 1-2 minutes on medium-high power.
Can I make this in a slow cooker?
Yes, but with adjustments! Combine all ingredients in your slow cooker and cook on Low for 2-3 hours, stirring occasionally. The texture will be more like a casserole than crispy baked potatoes. For best results, transfer to a baking dish and broil for 5 minutes at the end to crisp the top.
