Sweet Potato Cannelloni


Inspired by stuffed cannelloni, this vegetarian dish consists of blanched sweet potato slices wrapped around pureed sweet potato and diced apple, topped with shaved Parmesan and toasted walnuts. The remarkably rich taste and vibrant appearance make it a worthy-and healthful-addition to any dinner.

  • Servings: 6

  • 3 medium sweet potatoes (about 1 pound each)
  • 3/4 cup low-fat cottage cheese
  • 3/4 cup diced Fuji apple (skin on)
  • 3 tablespoons chopped fresh chives
  • 1 piece (2 ounces) Parmesan cheese, half grated and half shaved
  • 1/4 teaspoon coarse salt
  • Freshly ground pepper, to taste
  • Vegetable-oil cooking spray
  • 1 tablespoon walnut oil
  • 1/3 cup chopped toasted walnuts (about 1 ounce)


  1. Preheat oven to 375 degrees. Wrap 1 sweet potato in parchment, and then in foil. Pierce several times with a fork. Bake until tender, about 1 hour. Let cool. Reduce oven temperature to 350 degrees.

  2. Meanwhile, peel remaining sweet potatoes. Using a mandoline or a chef's knife, cut potatoes lengthwise into very thin slices until you have 30 slices. Trim each to a 2-by-4-inch rectangle.

  3. Bring a large pot of water to a boil. Add half the sweet potato slices, and cook until tender, about 2 minutes. Using a slotted spoon, place slices on a baking sheet to cool slightly. Repeat.

  4. Remove peel from baked sweet potato, and puree flesh in a food processor until smooth. Add cottage cheese, and puree until smooth.

  5. Transfer potato-cheese mixture to a large bowl. Stir in apple, chives, grated Parmesan, salt, and pepper.

  6. Coat a 9-by-13-inch baking dish with cooking spray. Place 1 heaping tablespoon filling in center of a sweet potato slice, and roll up. Place, seam side down, in dish. Repeat. (Cannelloni can be refrigerated, covered, overnight; bring to room temperature before baking.)

  7. Brush oil over cannelloni. Bake until heated through, 10 to 15 minutes. Sprinkle with walnuts and shaved Parmesan.

    Impressive results, but it was a 3 hour affair for my contribution to the pot luck. After reading others' comments, I used my squash casserole seasonings for the purée: roasted sweet potatoes with butter, brown sugar, salt, pepper, nutmeg, chives and grated sharp cheddar cheese were all tossed in the food processor. We sliced the potatoes to 1/8" thick with the mandolin. Used the colander insert in a pasta pot to boil 4-5 slices at a time. Longer slices worked best. Garnishes were perfect

    I didn't find this all that difficult....just time consuming and then it came out bland.

    If you are curious about trying this unique recipe I would say give it a shot- it's absolutely delicious. The apple was such a highlight for me.. I put a little extra apple and chive for more crunch. I will point out that it is time consuming and one crucial element is the mandolin. I had this old vintage looking mandolin that was so dull and it was very difficult to get thin slices. I ended up using a knife and it left me with chunkier pieces. Invest in a proper mandolin and you'll be fine!

    This was delicious! Made it for Thanksgiving Dinner. It was a little fussy to make the cannelloni, but well worth it. Sweet, salty with the parm and then a little sweet crunch with the apple. Not a single one left!

    I found this quite difficult to make, much like the other commentors, cutting the sweet potatoes the correct thickness was difficult and a mandoline is a MUST! The second time I made this I bought extra sweet potatoes, so when I messed some up I had plenty extra. I highly recommend buying extra!

    I bet this would be easier to just cut some thin slices of sweet potato and put them on the top, rather than trying to make 30 rolls.

    This recipe was terrific! It took some work, but I couldn't believe the depth of flavor from these simple ingredients. Definitely need a mandoline (1.5mm thickness was perfect) though. I did add a touch of cinnamon, cumin and a few ground cardamom seeds. Of the dozens of recipes I've made from this site, this was one of the most impressive, both visually and tasting.

    absolutely terrible! it ruined dinner as it took 2 hours to make and it fell apart. impossible to find sweet potatoes that will get you 30 2x4 inch slices, impossible to slice the potatoes thin enough, and like i said, it all fell apart in a terrible mess. awful awful awful

    I have tried this recipe twice and have not been able to slice the sweet potatoes thin enough to get them to roll without breaking, even when using a mandoline to slice. I ended up mashing the sweet potatoes and making a casserole both times. Not worth the effort!

    I haven't tried this but sounds like one could make 'lasagna noodles' instead.
