Let it set, then slice it and give it a crust. Spread warm leftover polenta in an oiled dish, let it firm up in the fridge, cut it into slabs or fingers, and grill, pan-fry or bake them until crisp and golden outside and soft within. Serve with mushrooms, a tomato sauce, braised greens or melted cheese.

Soft polenta, the spoonable kind from [our creamy polenta page](https://zestasy.com/wiki/creamy-polenta/), has one quality that looks like a flaw: as it cools, it sets. Leave the pot and come back later and you'll find a solid, sliceable block. That isn't a problem. It is half the reason to make polenta in the first place. Firm polenta cut into slices and grilled or fried is a dish in its own right, and leftovers are the easiest way to get there.

## Setting it

The cleaner you set it, the better it slices.

- **Spread it while it is still warm and soft.** Once it has cooled in the pot, it sets in a lumpy dome. If that has already happened, you can still slice it, just less neatly.
- **Use an oiled tray, baking dish or loaf tin,** or one lined with baking paper.
- **Smooth the top** with a wet spatula or the back of a spoon, to an even thickness, roughly the depth of a finger for slices that crisp outside and stay soft inside.
- **Cool, cover and chill** until it is completely firm. Overnight is ideal.

Like other cooked leftovers, keep it in the fridge and eat it within a couple of days. The Food Standards Agency's guidance is to [refrigerate leftovers within two hours and eat them within 48 hours](https://www.gov.uk/government/publications/how-to-chill-freeze-and-defrost-food-safely/how-to-chill-freeze-and-defrost-food-safely), or freeze them.

If you want a richer, more flavourful set, stir grated Parmesan, butter, herbs or a little chopped rosemary into the polenta before spreading it out.

## Slicing

Turn the block out onto a board and cut it with a large, wet knife. Slabs for grilling, fingers for frying, cubes for croutons, rounds with a cutter if you are feeling formal. Pat the cut surfaces dry with kitchen paper; a damp surface won't crisp.

## Four ways to cook it

### Grilled
Brush the slices with olive oil and lay them on a very hot griddle pan or barbecue. Leave them alone until they release on their own with dark stripes, then turn. If they stick, they are not ready to move. This is the version for serving under vegetables and sauces.

### Pan-fried
A thin layer of oil in a non-stick or well-seasoned pan, medium-hot. Fry the slices until a deep golden crust forms, then turn. Butter at the end for flavour. Dust them in a little flour or fine polenta first for an even crisper finish.

### Oven-baked
Toss fingers or cubes with oil and salt, spread them on a tray with plenty of space and bake in a hot oven, turning once, until golden on the outside. The least hands-on option, and perfect as polenta chips.

### Fried croutons
Small cubes fried in oil until crisp make good croutons for soup or salad, and a very good snack with something to drink.

## What to serve with it

Firm polenta is a blank, slightly sweet, corny canvas. It loves things that are savoury and saucy:

- **Mushrooms** fried until properly brown with garlic, thyme and a splash of wine.
- **A rich tomato sauce** with a spoon of ricotta and basil.
- **Braised greens**, such as chard or cavolo nero with garlic and chilli.
- **Melted cheese**: a slice of fontina, taleggio or gorgonzola laid on hot polenta until it slumps.
- **Caponata** or a pile of roasted peppers, for sweet-sour contrast.
- **A fried egg** on top, with black pepper.

## Turning it into something else

- **Polenta lasagne:** layer slices with tomato sauce, vegetables and cheese, then bake until bubbling.
- **Polenta pizza:** a firm slab, crisped first, topped with tomato and mozzarella and grilled.
- **Back to soft:** chop it up and warm it in a pan with milk or stock, whisking, until it loosens into a porridge again. Not quite the original, but a fine base for a stew.

## FAQ

### Why does our grilled polenta fall apart?
It wasn't fully set, it was cut too thin, or it was turned too early. Chill it well, cut thicker and wait for the crust to release on its own.

### Can we use the ready-made polenta that comes in a block?
Yes. The shop-bought logs are already set and sliceable, so they go straight to grilling, frying or baking.

### Can we freeze set polenta?
Yes. Wrap slices individually or separate them with baking paper, freeze, then thaw in the fridge before cooking.

### Which fat is best for frying it?
Olive oil gives the crispest result. Butter adds flavour but browns quickly, so add a knob towards the end.
