Ingredients of this Sweet Potato Crostini
The ingredients for this recipe are simple, fresh, and packed with flavor. You likely already have most of them in your kitchen.
The Sweet Potato Base:
- 2 large sweet potatoes (cut into ¼-inch-thick slices)
- 2 tablespoons extra-virgin olive oil
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
The Smoked Salmon Topping:
- 5 tablespoons whipped cream cheese
- 100 grams smoked salmon (torn into bite-sized pieces)
- 2 tablespoons fresh chives (finely chopped)
The Cranberry-Almond Topping:
- 5 tablespoons crème fraîche (or plain Greek yogurt as a substitute)
- 3 tablespoons dried cranberries (finely chopped)
- 3 tablespoons roasted salted almonds (chopped)
- 2 tablespoons fresh parsley (finely chopped)
Each topping offers something unique, but you’re free to get creative. Goat cheese, avocado, or even a drizzle of honey could be fun additions.
Step-by-Step Instructions
1. Prepare the Sweet Potato Base
Start by preheating your oven to 400°F (200°C). Line a large baking sheet with parchment paper to prevent sticking and make cleanup a breeze.
Slice the sweet potatoes into ¼-inch-thick rounds. It’s important to keep them even so they roast uniformly. Brush each slice with olive oil on both sides, then sprinkle with salt and pepper.
Arrange the slices in a single layer on the prepared baking sheet. Roast them in the oven for 17–20 minutes, flipping halfway through, until they’re golden brown and slightly crispy around the edges. Let the slices cool slightly before adding the toppings.
2. Assemble the Smoked Salmon Crostini
Take half of the roasted sweet potato slices and spread about 1 teaspoon of whipped cream cheese on each one. Don’t worry about being too precise—it’s all about getting that creamy goodness onto the base.
Next, top each slice with a piece of smoked salmon. Try to fold or layer the salmon for a bit of visual appeal. Finish with a sprinkle of chopped chives for a pop of color and flavor. These are best served immediately for maximum freshness.
3. Assemble the Cranberry-Almond Crostini
On the remaining sweet potato slices, spread about 1 teaspoon of crème fraîche. Again, plain Greek yogurt works perfectly if you want a slightly tangier flavor.
Add a small pile of chopped dried cranberries and almonds to each slice. Finally, sprinkle with fresh parsley to brighten up the dish. Just like the smoked salmon variation, these are best enjoyed right after assembling.
How to Serve this Sweet Potato Crostini
These Sweet Potato Crostini are so versatile that they’ll fit in just about anywhere. Here are a few serving ideas to inspire you:
- Party Platter: Arrange both versions on a large serving tray and let guests mix and match.
- Brunch Spread: Pair these with scrambled eggs, fresh fruit, and a big pot of coffee for a balanced, wholesome brunch.
- Light Dinner: Serve them alongside a hearty salad or a warm bowl of soup for an easy, comforting meal.
For an extra finishing touch, you can drizzle the smoked salmon crostini with a bit of lemon juice or olive oil and add a tiny pinch of flaky sea salt.
Tips for Perfect Crostini
- Choose Uniform Sweet Potatoes: Look for sweet potatoes that are relatively straight and evenly shaped. This will make slicing and roasting so much easier.
- Don’t Overcrowd the Pan: Give the sweet potato slices enough space to roast properly. Overcrowding can cause them to steam instead of crisp up.
- Make Ahead for Convenience: You can roast the sweet potato slices up to a day in advance. Just store them in an airtight container in the fridge and reheat in the oven for a few minutes before adding the toppings.
- Use Fresh Ingredients: Fresh herbs like chives and parsley make a big difference in flavor. Don’t skip them!
- Experiment with Toppings: This recipe is just a starting point. Feel free to get creative and try new combinations that suit your taste.
Sweet Potato Crostini Recipe Variations
This Sweet Potato Crostini recipe is endlessly adaptable, making it easy to tailor to your dietary preferences or flavor cravings.
- Vegetarian Option: Skip the smoked salmon and try a topping of mashed avocado, cherry tomatoes, and a sprinkle of feta cheese.
- Gluten-Free: This recipe is naturally gluten-free, but if you’re using store-bought crème fraîche or whipped cream cheese, double-check the labels.
- Vegan: Use a dairy-free yogurt or cashew cream in place of crème fraîche and cream cheese, and opt for plant-based toppings like roasted red peppers or hummus.
- Spicy Kick: Add a pinch of crushed red pepper flakes or drizzle the crostini with a bit of chili oil for some heat.
- Nut-Free: Substitute seeds like sunflower or pumpkin seeds for the almonds in the cranberry topping.
Storing and Reheating
If you have leftovers (though I doubt you will!), here’s how to store them:
- Refrigeration: Place the roasted sweet potato slices in an airtight container and store them in the fridge for up to 3 days.
- Freezing: You can freeze the plain roasted slices by laying them flat on a baking sheet until solid, then transferring them to a freezer bag. They’ll keep for up to 3 months.
To reheat, simply pop the slices in a preheated oven at 375°F (190°C) for 5–7 minutes, or until warmed through. Add the toppings just before serving.
