How to Make Mini Polenta Cake with Mushroom Duxelles
Step 1: Cook the Polenta
Bring the vegetable stock or water to a gentle simmer in a medium saucepan. Slowly pour in the polenta while whisking constantly this prevents clumping and keeps the texture silky. Once it thickens (about 5–7 minutes), lower the heat and continue stirring until the mixture starts to pull away from the sides of the pot. It should feel smooth and creamy, not gritty.
Stir in the butter and grated Parmesan (if using) until melted and glossy. Taste and season generously with salt and freshly cracked pepper. At this point, the polenta should be rich, buttery, and full of flavor think of it as your foundation layer, so it deserves a bit of care.
Step 2: Chill and Shape the Cakes
Line a small baking dish with parchment paper. Pour the hot polenta into the dish and spread it evenly to about ½ cm thickness. Smooth the surface with a spatula it doesn’t need to be perfect, just level.
Let the polenta cool at room temperature for 10–15 minutes, then transfer it to the refrigerator to chill for at least an hour (or overnight if you’re prepping ahead). Once firm, lift the set polenta out and use a round cutter or small ring mold to cut out neat circles about 4 cm wide.
These little rounds will become your mini cakes crisp on the outside, tender within.
Step 3: Sear the Cakes
In a non-stick skillet, heat a tablespoon of butter or olive oil over medium-high heat. When it shimmers, add the polenta rounds in batches don’t overcrowd the pan.
Sear each side for 2–3 minutes or until golden and lightly crispy. You’ll hear a soft sizzle and see a delicate crust forming. Gently flip them with a spatula, taking care not to break the edges. Transfer the seared cakes onto a warm plate lined with paper towels.
Tip: If you want an extra crisp crust, finish them in a 400°F (200°C) oven for 5 minutes after searing.
Step 4: Make the Mushroom Duxelles
Finely chop the mushrooms until they resemble coarse crumbs the smaller the pieces, the more evenly they’ll cook. In a skillet, melt a tablespoon of butter or warm olive oil over medium heat.
Add the minced shallot and garlic first, cooking until translucent and fragrant (about 2 minutes). Then stir in the mushrooms and thyme. They’ll release liquid as they cook let that moisture evaporate completely while you stir occasionally.
After 8–10 minutes, you’ll notice the mixture turning darker, richer, and starting to cling to the pan. That’s when it’s perfect. Season generously with salt and pepper. The duxelles should taste deeply savory, almost meaty, with an aromatic hint of thyme.
Optional: For extra depth, stir in a teaspoon of dry white wine or a splash of cream at the end and cook for another minute.
Step 5: Prepare the Truffle Foam
Pour the heavy cream into a small saucepan and warm it gently over low heat don’t let it boil. Stir in the truffle oil (or finely minced truffle if you’re lucky enough to have one) and a pinch of salt.
If using a foaming agent like soy lecithin, add it now. Remove from heat and use an immersion blender to aerate the mixture until a soft, airy foam forms on top. You’ll see tiny bubbles and a luxurious aroma rising from the pot that’s your truffle foam ready to spoon.
Keep it warm while you assemble so it holds its shape.
Step 6: Assemble and Serve
To assemble, place each warm polenta cake on a serving plate or platter. Spoon a small mound of the mushroom duxelles on top of each one enough to cover the surface but not overflow. Then, using a small spoon or piping bag, gently place a dollop of truffle foam on top or slightly to the side of the duxelles.
Garnish with a few fresh thyme leaves or a delicate sprinkle of Parmesan if desired.
Serve immediately while the polenta is still crisp and the foam light and fragrant. Each bite should feel like a perfect harmony of buttery, earthy, and aromatic the kind of elegant simplicity that always impresses.
What to Serve With It
- A crisp arugula salad with lemon and shaved Parmesan.
- Roasted asparagus with olive oil and sea salt.
- A light glass of Pinot Grigio or sparkling water with a citrus twist.
Tips for Perfect Results
- Finely chop the mushrooms so they cook down evenly and create a smooth duxelles.
- Let the polenta chill completely before cutting this keeps the cakes firm and easy to handle.
- Serve immediately after adding the foam to maintain its delicate texture.
Storage Instructions
Keep leftover polenta cakes in an airtight container for up to 3 days in the refrigerator. Reheat them in a skillet until warm and crisp again.
The duxelles can be made ahead and stored for up to 4 days. The foam, however, is best made fresh.
