Preview: This potato and sweet potato mash makes a beautiful and tasty side dish that’s not overly sweet and cloying.
Are you tired of sweet potato casseroles that make you feel like you need a can of Redi-Whip to top them off?
I love a good sweet potato pie–for dessert. But when I’m eating turkey, roast beef, or even green bean casserole, it doesn’t seem fittin’ to plop a brown-sugar, butter-saturated spoonful of sweet potatoes down next to them.
If you feel the same way, this recipe is a beautiful alternative.

Why is mixing these potatoes a good idea?
So often, a dish of 100% sweet potatoes can be cloying.
Adding white potatoes seems to mellow out the sweet potatoes. They also complement each other texture and taste-wise.
If you have a lonely potato or two sitting on your kitchen counter, add it to potatoes of the other color. For example, if you only have one or two sweet potatoes, make up the difference with more white potatoes. It doesn’t matter.
FAQ about Mashed Potatoes and Sweet Potatoes:
I don’t recommend it. Real yams are entirely different root vegetables that are more like yucca in texture and flavor. They are not even in the same family as sweet potatoes. In the United States, yams are not seen very often in grocery stores unless you go to a specialty market.
White sweet potatoes and purple sweet potatoes (if you can find them) are generally interchangeable. Both varieties tend to be denser and starchier.
The novelty of the orange and white colors will be for naught if you use the white sweet potatoes. The purple potatoes may bleed into the white potatoes when you make the swirl since they are boiled first.
How do you prevent the colors from bleeding if you use purple potatoes? Mary-Frances Heck, author of Sweet Potatoes suggests roasting, sautéeing, or frying. As you can imagine, purple bleeding would blur the swirl effect in a bad way.
Yukon Gold or russets are best, in that order. The variety and age of your potatoes affect how much milk you need to add. Start with less and add more milk only as need it to get the best texture.
No, you can leave them unpeeled if you prefer. Scrub them well and cut into chunks. Leaving the skins on will give some texture and extra fiber.
Suit yourself on this one. You can peel both types of potatoes (specified in the recipe), or just the sweet potatoes, or don’t peel (but do scrub) at all.
What do I serve with this side dish?
Whenever you would serve mashed potatoes is a good time to serve this casserole. Try a little gravy over the top.
If you’re trying to cut back on gravy, this recipe is also a good way to go. The sweet potatoes add flavor.
Don’t save this dish for the fall and winter holidays alone. It’s perfect with grilled meats–especially something spicy like sausage.

Potato and Sweet Potato Mash
White potatoes and sweet potatoes are cooked together, mashed separately, then swirled together to make an interesting and tasty side dish.
Ingredients
- 1 1/2 pounds white potatoes, peeled and diced into 2-inch pieces
- 1 1/2 pound sweet potatoes, peeled and diced into 2-inch pieces
- 1 teaspoon salt
- 6 Tablespoons butter (divided)
- 2/3 cup warmed milk (divided)
- Salt to taste
- Freshly ground pepper
Instructions
- Place white potatoes into the bottom of a saucepan, then sweet potatoes on top. Add 1 teaspoon salt. Barely cover potatoes with cold water. Bring to a boil, then reduce to simmer until potatoes are fork-tender but not falling apart.
- Drain potatoes. Remove sweet potatoes from the pan and place them into another bowl. Place white potatoes back into your original pan and let them dry while you mash the sweet potatoes. For this step, I put on exam gloves (which I always have in my kitchen) to remove the hot sweet potatoes.
- Mash the sweet potatoes your favorite way. (I use a ricer, but a potato masher or portable mixer is also good.)
- Start with about 2 tablespoons of warm milk. Add more, if needed, to make potatoes creamy and smooth but not runny. Season with salt and pepper to taste.
- Repeat steps 3 and 4 with the white potatoes. Again, start with about 2 tablespoons of milk. Add more milk, as needed, until the consistency matches your sweet potatoes.
- Plop mashed sweet potatoes back into the pan with mashed white potatoes. Make a couple of folds with a spoon to barely mix. Move to a serving dish being careful not to mix too much.

I had the same idea. Somebody gave me a couple cans of sweet potatoes/yams (I know they aren't the same thing but people want to MASH the two, heh, so let's let them) and I had before just ate them by themselves and didn't like them. I was going to either regift the cans to a foodbank or someone else, or use them in a recipe. Mixing them in with mashed regular potatoes, which I love, was my easier idea, since I am NOT a cook/chef. I figured it would be a nice color addition and would get rid of them easiest, lol! Will try!

Hi Nan, Another delicious thing to do with sweet potatoes is to use them in breadmaking. See this recipe.

Fantastic! I really like the idea of mixing the two. I love sweet potatoes but the rest of the family not so much. I think this would be a great option for us all and just maybe they will love the two mixed together. Your pictures are beautiful.
