Sweet Potato Cannelloni: A Symphony of Autumn Flavors

I remember the first time I made sweet potato cannelloni. It was late October, the air crisp and carrying the scent of woodsmoke. I was hosting a small Thanksgiving gathering for friends who, like me, were far from home. I wanted something that felt festive and familiar, yet also a little bit different. The vibrant orange of the sweet potatoes, transformed into delicate pasta-like sheets, filled me with an artistic excitement. The combination of sweet, savory, and nutty notes, all nestled within those tender rolls, was a revelation. It was an instant hit, and it’s been a staple of my autumn cooking ever since.

Dietary Type: Vegetarian

Ingredients

3 sweet potatoes (about 1 pound each)
¾ cup low fat cottage cheese
¾ cup Fuji apple, diced (skin on)
3 tablespoons fresh chives, chopped
1 ounce Parmesan cheese, grated
1 ounce Parmesan cheese, shaved
¼ teaspoon coarse salt
Fresh ground pepper, to taste
Oil, for the baking pan
1 tablespoon walnut oil
1 ounce walnuts, toasted, chopped

Equipment Needed

Baking sheet
Parchment paper
Aluminum foil
Fork
Mandoline or chef’s knife
Large pot
Slotted spoon
Food processor
Large bowl
9-by-13-inch baking dish

Instructions

Preheat your oven to 375°F (190°C). Wrap 1 of the sweet potatoes in parchment paper, and then wrap it in aluminum foil. Pierce the wrapped sweet potato several times with a fork. This creates steam and prevents bursting.
Bake the wrapped sweet potato until it is very tender, about 1 hour. You should be able to easily pierce it with a fork. Let it cool completely. You can do this ahead of time. Once cooled, reduce the oven temperature to 350°F (175°C).
While the wrapped sweet potato is baking, peel the remaining 2 sweet potatoes. This is crucial for achieving that smooth, pasta-like texture.
Using a mandoline (for consistent thickness) or a very sharp chef’s knife, carefully cut the peeled sweet potatoes lengthwise into very thin slices. Aim for slices that are approximately 1/16 inch thick. You’ll need about 30 slices in total.
Trim each sweet potato slice into a 2-by-4-inch rectangle. This will ensure uniform cannelloni and a neat presentation. Don’t discard the trimmings; roast them for a snack!
Bring a large pot of water to a rolling boil. Adding a pinch of salt is optional.
Add half of the sweet potato slices to the boiling water and cook until they are just tender, about 2 minutes. Overcooking will make them too fragile to roll.
Using a slotted spoon, carefully remove the blanched sweet potato slices from the boiling water and place them on a baking sheet to cool slightly. This prevents them from sticking together. Repeat with the remaining slices.
Remove the peel from the baked sweet potato. It should slip off easily.
Puree the flesh of the baked sweet potato in a food processor until smooth. This is the base of your creamy filling.
Add the ¾ cup low-fat cottage cheese to the food processor and puree until the mixture is completely smooth. The cottage cheese adds a tangy richness.
Transfer the sweet potato-cheese mixture to a large bowl.
Stir in the ¾ cup diced Fuji apple (skin on), 3 tablespoons chopped fresh chives, 1 ounce grated Parmesan cheese, ¼ teaspoon coarse salt, and fresh ground pepper to taste. Taste and adjust seasonings as needed. The apple adds a welcome sweetness and texture.
Coat a 9-by-13-inch baking dish generously with oil to prevent sticking. Olive oil or vegetable oil work well.
Place 1 heaping tablespoon of the sweet potato filling in the center of a sweet potato slice, and gently roll it up, like a tiny blanket.
Place the rolled cannelloni, seam side down, in the prepared baking dish. Repeat with the remaining slices and filling. At this point, the cannelloni can be refrigerated, covered, overnight. Bring to room temperature before baking.
Brush the tops of the cannelloni lightly with the 1 tablespoon walnut oil. This adds a nutty flavor and helps them brown beautifully.
Bake the cannelloni in the preheated oven until heated through, about 10 to 15 minutes.
Sprinkle the baked cannelloni with the 1 ounce toasted, chopped walnuts and 1 ounce shaved Parmesan cheese. Serve immediately.

Expert Tips & Tricks

Slicing: The key to success is slicing the sweet potatoes thinly and evenly. A mandoline is ideal, but a very sharp chef’s knife and a steady hand will also work.
Blanching: Don’t overcook the sweet potato slices during blanching. You want them pliable, not mushy.
Make-Ahead: As mentioned, you can assemble the cannelloni a day ahead and bake them just before serving. This is a great time-saver.
Filling Flavor: Feel free to experiment with the filling. A pinch of nutmeg or cinnamon would complement the sweet potato beautifully.
Prevent Sticking: Make sure the baking dish is well-oiled to prevent the cannelloni from sticking.

Serving & Storage Suggestions

Serve the sweet potato cannelloni warm, as a starter or a light main course. They pair well with a simple green salad or roasted vegetables.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals. They can also be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions):

Q: Can I use a different type of apple?

A: Yes, any firm, slightly tart apple like Granny Smith or Honeycrisp will work well. The Fuji apple simply provides a nice balance of sweetness and crispness.

Q: What if I don’t have a mandoline?

A: While a mandoline makes the job easier, you can use a very sharp chef’s knife to thinly slice the sweet potatoes. The key is to aim for consistent thickness.

Q: Can I use butternut squash instead of sweet potato?

A: Yes, butternut squash can be used as a substitute for the sweet potato. The flavor will be slightly different, but the texture will be similar.

Q: How can I prevent the sweet potato slices from curling up while baking?

A: Blanching the slices briefly in boiling water helps to make them more pliable and less likely to curl. Also, be sure to place them seam-side down in the baking dish.

Q: Is it necessary to use walnut oil?

A: No, you can use olive oil or any other neutral-flavored oil as a substitute. Walnut oil adds a subtle nutty flavor that complements the other ingredients.
