The short stovetop stage is only the beginning of these polenta bites. A shallow slab must chill until firm enough to cut before its rectangles go into a hot oven. Allow 150 minutes overall, including at least 90 minutes of refrigeration, and longer if it has not set. The batch makes 24 bites, or six portions of four.
Rosemary-Parmesan polenta bites makes 6 servings, with 2 hr 30 min estimated total time. View the standalone recipe page.
Match the polenta to the recipe before starting
Choose quick-cooking polenta labeled for approximately five minutes on the stovetop and compatible with the listed 180 g polenta to 720 g water. Traditional coarse polenta and ready-made polenta tubes are different products. If a packet requires a different liquid ratio, select a matching product rather than silently changing this recipe's yield and setting behavior.
Line a 20 cm square metal pan with parchment, leaving handles on two sides. Prepare the finely chopped rosemary, butter and grated Parmesan before heating the water. Separate the Parmesan into 35 g for the cooked mixture and 15 g for the oven finish. The thickened polenta needs to be spread promptly once it is ready.
Whisk while adding, then stir as it thickens
Bring the water and 2 g salt to a boil in a medium saucepan. Add the polenta in a thin stream while whisking continuously. Dumping it in as a mound makes it harder for liquid to reach individual grains evenly. Lower the heat and stir firmly and frequently as the mixture thickens over the specified cooking time.
It should be very thick and tender before leaving the heat. Stir in the 20 g butter, 35 g Parmesan, 3 g rosemary and pepper, reaching the corners of the saucepan. Cheese should be distributed through the whole mixture, not left in a pocket at the bottom. Scrape it immediately into the lined pan.
Set the slab in the refrigerator, not on the counter
Spread an even layer, approximately 2 cm deep, using a damp spatula. Work into the corners and smooth any ridges that would later produce unusually thin or thick bites. Leave the shallow pan for ten minutes to stop heavy steaming, then refrigerate it loosely covered. This initial pause is not a room-temperature setting stage.
Chill for at least 90 minutes, until cold and firm enough to lift and cut. Time alone is not proof of firmness. If the slab bends or slumps badly, keep it refrigerated longer. During the final 15 minutes of chilling, heat the oven to 450°F (230°C) so it is ready when the pieces are cut.
Cut evenly and leave turning room on the tray
Lift the cold slab using the parchment handles. Cut four rows by six columns to make 24 equal rectangles. A consistent grid keeps the portions predictable and the edges comparable during baking. Brush a large rimmed sheet with 10 g oil, then arrange the pieces with space between them rather than rebuilding a solid slab.
Brush the tops with the remaining 10 g oil. Bake for 25–30 minutes, turning carefully with a thin spatula after 15 minutes. Slide underneath before lifting so the tool supports each piece. The edges should become crisp and golden, while the center of the thickest bite reaches 165°F (74°C), the recipe's reheating endpoint.
Finish the cheese late and serve after a short pause
Scatter the remaining 15 g Parmesan over the bites for the final three minutes of baking. Adding it at the beginning would expose the fine cheese to the full high-temperature bake. Let the finished bites stand for five minutes, then serve four rectangles per person. The brief pause is included in the overall plan.
Leftovers belong in shallow containers in the refrigerator within two hours, or one hour above 90°F (32°C). Store at 40°F (4°C) or colder for three to four days and reheat to 165°F (74°C). Stored bites will lose some crispness; the original edge texture is best immediately after baking and the short serving rest.
Common questions
Why does my polenta fall apart when I cut it?
It may not have cooked thick enough, the product may require a different water ratio, or the slab may still be warm. Verify the specified product and give the slab more refrigerator time if needed. Do not use the oven to rescue an uncut soft mass.
Can I skip the ninety-minute chill?
No. The cold, firm slab is what allows 24 separate rectangles to be lifted, oiled and turned. The stated 150-minute total already includes this stage; it is not a quick five-minute polenta recipe from start to serving.
