Cost: $9.99 total, $2.50 per serving

Ingredients

  • 1.5 cups Coarse Cornmeal (Polenta) (dry, unsifted)
  • 4 cups Chicken Stock (low‑sodium, homemade or store‑bought)
  • 2 tablespoons Unsalted Butter (cut into small cubes)
  • 100 ml Half‑and‑Half (room temperature)
  • 1 teaspoon Kosher Salt (plus extra to taste after cooking)
  • ½ cup Parmesan Cheese (freshly grated)
  • ¼ cup Cheddar Cheese (optional) (shredded, adds extra richness)
  • 1 tablespoon Olive Oil (for sautéing toppings)
  • 1 cup Cherry Tomatoes (halved, lightly salted)
  • 1 cup Mushrooms (sliced, sautéed)
  • 2 cloves Garlic (thinly sliced, fried until crispy)

Instructions

  1. Prepare the Sous Vide Bath

    Fill the water‑bath container with enough water to fully submerge the bag, attach the sous vide circulator, and set the temperature to 83°C.

    Time: PT5M

    Temperature: 83°C

  2. Combine Base Ingredients in a Bag

    Place the cornmeal, chicken stock, butter, and 1 tsp salt into a vacuum‑seal bag. Add the half‑and‑half (100 ml) as well.

    Time: PT5M

  3. Vacuum‑Seal the Bag

    Seal the bag using a vacuum sealer or the water‑displacement method for zip‑lock bags, ensuring no air pockets remain.

    Time: PT5M

  4. Sous Vide Cook – First Hour

    Submerge the sealed bag in the pre‑heated water bath and cook for 1 hour. This allows the cornmeal to hydrate and begin thickening.

    Time: PT1H

    Temperature: 83°C

  5. Massage the Polenta

    After 1 hour, remove the bag, open it, and using a clean rag or spatula, gently massage the polenta for 1–2 minutes to break up any clumps and ensure uniform texture.

    Time: PT2M

  6. Continue Sous Vide for 15 Hours

    Return the bag to the water bath and let it sit for an additional 15 hours at 83°C. No further action is required.

    Time: PT15H

    Temperature: 83°C

  7. Reheat Before Finishing

    When ready to serve, remove the bag from the bath. If you prefer not to re‑enter the sous vide, place the bag in a pot of simmering water (just below a boil) for 25–30 minutes, stirring gently.

    Time: PT30M

    Temperature: Simmer (≈95°C)

  8. Incorporate Creaminess

    Transfer the hot polenta to a large mixing bowl. Whisk in the remaining half‑and‑half until fully incorporated, then stir in the grated Parmesan and optional shredded Cheddar until melted and smooth. Adjust salt if needed.

    Time: PT5M

  9. Portion and Chill

    Spoon the creamy polenta into jars or airtight containers, leaving about 1 cm headspace. Let cool to room temperature, then refrigerate for up to 3 days or freeze for longer storage.

    Time: PT10M

  10. Prepare Toppings (Optional)

    While the polenta cools, sauté mushrooms in olive oil until golden, season with salt. Halve cherry tomatoes, toss with a drizzle of olive oil and salt. Fry thin garlic slices until crisp.

    Time: PT10M

    Temperature: Medium‑high heat

  11. Reheat Served Portions

    When ready to eat, microwave a jar of polenta for 2 minutes 20 seconds (or until steaming). Stir, then top with sautéed mushrooms, tomatoes, crispy garlic, and an extra sprinkle of Parmesan.

    Time: PT3M

    Temperature: Microwave high

Frequently Asked Questions

Everything you need to know about this recipe

Q

What is the cultural significance and history of polenta in Italian cuisine?

A

Polenta originated as a staple peasant food in Northern Italy, made from coarse cornmeal boiled with water or stock. Over centuries it evolved from a simple porridge to a versatile dish served creamy, grilled, or fried, and today it appears on both rustic and fine‑dining menus.

cultural
Q

What are the traditional regional variations of polenta in Italian cuisine?

A

In the Alpine valleys of Piedmont and Valle d'Aosta, polenta is often enriched with butter and cheese. In Veneto and Lombardy, it may be served soft with ragù, while in the Veneto lagoon it is sometimes fried into crisp cakes called "polenta fritta."

cultural
Q

How is polenta traditionally served in Northern Italy?

A

Traditionally, a soft, creamy polenta is ladled onto a wooden board, topped with melted butter, grated cheese, and sometimes a meat ragù. Once set, it can be sliced and grilled or fried for a crisp exterior.

cultural
Q

What occasions or celebrations is polenta associated with in Italian culture?

A

Polenta is a comfort food for everyday meals but also appears at harvest festivals and winter gatherings, where its hearty nature pairs well with stews, sausages, and robust cheeses.

cultural
Q

What makes this 16‑hour sous vide polenta special in Italian cuisine?

A

The sous vide method eliminates the need for constant stirring, delivering a consistently creamy texture every time. The long, low‑temperature cook allows the cornmeal to fully hydrate, resulting in a silkier mouthfeel than traditional stovetop methods.

cultural
Q

What are the most common mistakes to avoid when making this sous vide polenta?

A

Common errors include sealing the bag with air pockets, setting the water bath temperature too high (which can cause grainy texture), and failing to massage the polenta after the first hour, which leads to uneven consistency.

technical
Q

Why does this recipe use a sous vide bath instead of traditional stovetop cooking?

A

Sous vide provides precise temperature control and hands‑free cooking, preventing the polenta from scorching or becoming lumpy. It also ensures every batch is identical, which is ideal for meal‑prep.

technical
Q

Can I make this sous vide polenta ahead of time and how should I store it?

A

Yes. After the 16‑hour cook, portion the polenta into airtight jars and refrigerate for up to 3 days or freeze for up to 2 months. Reheat gently in a simmering water bath or microwave before serving.

technical
Q

What texture and appearance should I look for when the polenta is done?

A

The finished polenta should be smooth, glossy, and uniformly thick with no visible dry cornmeal pockets. When lifted with a spoon, it should flow like a thick cream and coat the spoon without breaking.

technical
Q

How do I know when the sous vide polenta is done cooking?

A

After the initial 1‑hour soak, the cornmeal will have fully absorbed the liquid and the mixture will be thick but still fluid. After the additional 15‑hour period, the polenta will be dense yet creamy; a quick taste should reveal a fully cooked, tender grain.

technical
