If you're searching for the perfect appetizer that is elegant, easy, and impossible to stop eating, these crispy roasted polenta bites are about to become your new obsession.
Golden on the outside, creamy within, and topped with a silky cashew spread plus roasted vegetables, they have everything you want in a finger food: texture, richness, flavor, and a presentation worthy of any dinner party.
Not only are they naturally gluten-free and vegan, but they also bake beautifully, no frying required.
Polenta has long been celebrated in Italian kitchens for its versatility, turning from creamy porridge to crisp appetizer base with just a bit of cooling and roasting.
These polenta bites are especially popular during autumn and winter gatherings (think Thanksgiving, Christmas, cozy dinner parties), when roasted pumpkin and rich, savory toppings shine.
It's the kind of appetizer that looks impressive yet requires minimal hands-on time, a host's dream.
Ingredients
These ingredients were chosen because each one adds depth, texture, or contrast. Polenta gives structure and crunch, the cashew-miso spread adds umami creaminess, and the vegetables bring brightness and complexity. Feel free to swap toppings depending on the season.
- Polenta - Creates the crispy, golden base with a naturally mild flavor that allows toppings to shine.
- Water - Hydrates the cornmeal and ensures a firm consistency once cooled.
- Salt
- Cashews - When blended, make a rich, spreadable vegan cream perfect for topping.
- Miso - Adds savory umami depth to the cashew spread.
- Roasted pumpkin - Sweet, caramelized, and seasonal.
- Artichokes in oil - Briny, tender, and a fantastic contrast to the crispy base.
- Sun-dried tomatoes in oil - Intensely flavored and chewy, balancing out creamy and crunchy components.

Instructions
Cook the Polenta
Bring water to a boil, add the salt, then pour in the polenta in a steady stream. Immediately remove from heat and whisk vigorously to prevent lumps. Return to low heat and cook according to package directions until thick and pulling away from the sides of the pot.
Spread and Cool
Line a baking sheet with parchment paper and spread the cooked polenta evenly. Cover with another baking sheet and use a rolling pin to make it even. The thinner the layer, the crispier the bites, about ½ cm to 1 cm works really well. If you want it to have a bit more bite to it then keep it around 1 cm. Let it cool completely. this step is essential for ensuring the structure holds when cut. I like to leave it on the table with the window open in winter, works great!
Cut and Brush
When it's starting to cool, preheat oven to 250°C/480°F. Slice the cooled polenta into squares or rectangles.
Brush lightly with olive oil on both sides.
Roast
Place on a baking sheet and bake 15-20 minutes, flipping once, until crisp and deep golden.
Top and Serve
Spread each crispy bite with cashew cream or another spread, then garnish with roasted pumpkin, artichokes, or sun-dried tomatoes.
If you want to make the cashew cheese, simply soak 150g of cashews overnight, then blend them with 1 teaspoon of miso paste until creamy, adding some water if necessary. You can leave it to ferment at room temperature in a jar covered with a cheese cloth/kitchen paper secured with an elastic for 24 hours or simply leave it in the fridge.
Substitutions
Pumpkin - Swap with roasted sweet potato, caramelized carrots or onions
Cashew spread - Replace with vegan ricotta, hummus, or blended white beans for a nut-free option.
Artichokes - Use olives, capers, or grilled zucchini for a Mediterranean twist.
Sun-dried tomatoes - Try roasted red peppers or confit cherry tomatoes.
Storage
Polenta bites store well:
Refrigerate the plain roasted squares for 3-4 days. Reheat in a hot oven for 5-6 minutes to restore crispiness.
You can also make them ahead of time, leave them cut into squares, store them in an airtight container and roast them when needed.
Do not refrigerate fully assembled bites, as toppings may make them soggy.
Top Tip
Don't underseason the toppings. Because polenta itself is mild, the cashew spread and vegetables can bring bold flavors. Taste and adjust as you assemble.
