Ingredients for sweet potato cannelloni

Sweet potatoes, celery crowns, and creamy spices—this recipe turns simple ingredients into a showstopping dish.

Sweet potatoes are the star here. Organic or heirloom varieties have the best flavor, but any firm, unblemished ones work. Roast them until fork-tender—about 45 minutes at 400°F—so they mash easily into that velvety custard. I always grab the orange-fleshed ones at Trader Joe's; they're sweeter and hold up better. Skip the pre-cut bags—they dry out fast. For extra richness, some folks add a splash of vanilla extract to the filling, but I keep it simple with just cinnamon and nutmeg.

No celery crowns? Celery sticks with tops left on work in a pinch—just blanch them 30 seconds to soften. The pasta shells can be homemade, but store-bought jumbo shells save time. If you're feeling fancy, toast them in the oven with olive oil before assembling. For the cream, half-and-half works too, but full-fat gives that restaurant-quality texture. The maple syrup isn't mandatory—just a touch to balance the spices. Pro tip: Save the celery leaves for garnish or stock.

Roasted sweet potatoes keep 3 days in the fridge—perfect for meal prep. The assembled cannelloni reheats best at 350°F for 15 minutes, covered with foil. For extra crunch, toast the celery crowns in the oven for 5 minutes before serving. Leftovers? Freeze for 2 months—just thaw overnight in the fridge. Garnish with Parmesan and fresh herbs right before serving, or they'll wilt. Trust me, the celery crowns stay crispy if you bake them uncovered at the end.

Step-by-step instructions for sweet potato cannelloni

Here's how to build these decadent cannelloni with crispy celery crowns and spiced sweet potato filling.

Preheat your oven to 400°F. Pierce the 2 lb large sweet potatoes with a fork in several places, then rub them with 1 tbsp olive oil. Roast for 45-50 minutes until they yield easily to a fork and the edges are caramelized. You want them tender enough to mash smoothly but not falling apart.

While they roast, here's the thing—don't cut into them too early. The skin helps protect the moisture. Once they're done, let them cool for 10 minutes before handling. This makes peeling and mashing much easier. I like to scoop out the flesh with a spoon, leaving the skin behind.

In a large bowl, combine the roasted sweet potato flesh with 0.5 cup heavy cream, 1 tbsp maple syrup, 1 tsp cinnamon, 0.5 tsp nutmeg, 1 tsp salt, and 0.5 tsp black pepper. Mash with a potato masher or fork until smooth but still slightly textured—you want that rustic look in your filling.

Taste and adjust seasoning if needed. I usually add a pinch more cinnamon because it's hard to overdo with sweet potatoes. This filling should be thick enough to hold its shape when stuffed but still spreadable. If it's too thick, stir in a splash of warm milk or cream.

Boil the 12 oz pasta shells in salted water for 2 minutes less than package instructions (they'll finish cooking in the oven). Drain and rinse briefly with cold water to stop cooking, then spread them on a baking sheet. Brush each shell generously with melted 2 tbsp butter—this creates a golden crust when baked.

Here's a pro tip: I like to stuff the shells right after boiling while they're still warm and pliable. If they cool completely, they become too stiff to fill. Keep them covered with a damp towel while you prep the filling to maintain their flexibility.

Preheat your oven to 375°F. Using a piping bag or spoon, carefully fill each pasta shell with about 2 tablespoons of the sweet potato mixture. Don't overstuff—they'll expand slightly in the oven. Place the filled shells in a greased 9x13-inch baking dish.

Pour the remaining heavy cream over the top, then sprinkle with 0.25 cup grated parmesan cheese and 2 cloves minced garlic cloves. Cover with foil and bake for 25 minutes. Uncover and bake another 10 minutes until bubbly and golden.

Just before serving, toast the 1 package celery crowns in a dry skillet over medium heat for 3-4 minutes until crispy and golden. Watch them closely—they burn quickly. Sprinkle these over each serving of cannelloni right before eating to add that satisfying crunch.

Let the cannelloni rest for 5 minutes before serving—this helps everything set up nicely. The sauce should be creamy but not watery, and each bite should deliver that perfect balance of sweet, spiced filling with crispy celery crowns on top. Serve with a simple arugula salad to cut through the richness.

Dietary considerations for this recipe

Vegetarian-Friendly Base

This recipe is naturally vegetarian, making it perfect for plant-based diets or meat-free meals. The filling relies entirely on roasted sweet potatoes, heavy cream, and warm spices like cinnamon and nutmeg. For extra protein, stir in 1 cup cooked lentils or ½ cup crumbled feta cheese to the filling. 🌱

Gluten-Free Adaptation

To make this gluten-free, simply swap the pasta shells for gluten-free jumbo shells like Barilla or Jovial. I recommend checking labels for cross-contamination warnings if you have severe gluten sensitivity. The sweet potato filling remains completely gluten-free as written, so no other substitutions are needed. 🥔

Dairy-Free Options

For a dairy-free version, replace the heavy cream with ½ cup full-fat coconut milk and the butter with vegan butter or olive oil. Use dairy-free parmesan for garnish, like Violife or Follow Your Heart brands. The filling will still be creamy but with a slightly lighter texture. 🥥

Lower-Carb Version

To reduce carbs, use zucchini noodles or spaghetti squash as a base instead of pasta shells. For the filling, roast sweet potatoes as usual but reduce the amount to 1 lb total.

Add 1 tbsp almond flour to the filling to help bind it. This version keeps the dish hearty while cutting carbs significantly. 🥦

Allergen Considerations

This recipe contains dairy (cream, butter, parmesan) and gluten (pasta shells). For nut allergies, avoid maple syrup brands processed in nut facilities. Always check labels on celery crowns and pasta shells for potential allergens. I recommend keeping a separate set of tools for handling allergens if needed. 🚫
