Steps

Before you start

Measure all ingredients before starting so you can work quickly when adding the cornmeal.
Use a 4- to 6-quart slow cooker for best results; too small and the polenta may boil over.
Have a whisk handy to combine the cornmeal and cold broth—this prevents lumps.

1
Whisk cornmeal and cold broth
- In a bowl, whisk together the cornmeal and cold broth until smooth and lump-free.
- Let sit for 2 minutes so the cornmeal fully hydrates.

Ready when: No visible lumps in the mixture
Tip: Whisking prevents lumps from forming when the cornmeal hits hot liquid.
2
Pour warm broth into slow cooker
- Pour the 4 cups of warm vegetable broth into your 4- to 6-quart slow cooker.
- Add 1½ teaspoons of kosher salt.

Tip: Warm broth helps the polenta cook more evenly and quickly.
3
Add cornmeal mixture to slow cooker
- Slowly pour the cornmeal mixture into the warm broth while stirring constantly with a whisk.
- This distributes the cornmeal evenly and prevents clumping.
- Stir for about 1 minute to incorporate everything.

Ready when: Mixture is smooth and evenly combined with no visible dry spots
Tip: Slow, steady whisking is crucial—rushing causes lumps that won't break down in the slow cooker.
4
Cook on low
- Cover the slow cooker and cook on the low setting for 4 hours.
- Stir every 30 minutes for the first 2 hours, then every hour after that.
- The mixture will bubble gently around the edges and thicken gradually.

Ready when: Polenta is very creamy, pulls away slightly from the sides of the cooker, and a wooden spoon drawn through leaves a slight trail
Tip: Stirring prevents a skin from forming on top and helps the texture stay smooth and uniform.
5
Finish with butter and cheese
- Turn off the slow cooker.
- Stir in the 4 tablespoons of cold butter pieces, then fold in the 1½ cups of shredded sharp cheddar cheese.
- Stir until the cheese is completely melted and the butter is incorporated.
- The polenta should be glossy and very creamy.

Ready when: Cheese and butter are fully melted; polenta is smooth and glossy
Tip: Add butter and cheese off the heat so the cheese stays creamy rather than becoming stringy.
6
Season with herbs and spices
- Stir in the ¼ cup fresh chopped parsley, 1 teaspoon fresh thyme, and ½ teaspoon freshly ground black pepper.
- Taste and adjust salt if needed.
- The polenta should taste rich, herbaceous, and well-seasoned.

Ready when: Herbs are evenly distributed and seasoning is balanced
Tip: Fresh herbs added at the end brighten the flavor and maintain their vibrant color.
7
Serve or hold warm
- Spoon the polenta into bowls or onto plates while still warm.
- If holding for serving later (up to 30 minutes), cover the slow cooker loosely with a lid and keep it on warm.
- If the polenta thickens too much while resting, thin it with a splash of warm broth or butter.

Tip: Polenta sets quickly as it cools; serve warm for the best creamy texture.

Tips

For deeper flavor, toast the dry cornmeal in a dry skillet over medium heat for 2–3 minutes before whisking with cold broth. This adds a nutty, roasted note.
If your slow cooker runs hot, polenta may cook faster (3.5 hours) or cook unevenly. Check after 3 hours and adjust stirring frequency if needed.
Polenta pairs beautifully as a base for braised short ribs, mushroom ragù, or spicy sausage. It also works as a side for roasted vegetables.
For a looser, pourable polenta (suitable for topping), add an extra ½ to 1 cup of warm broth in step 5 before serving.

Make ahead

You can partially prepare the polenta up to 1 day ahead: whisk the cornmeal with cold broth (step 1) and refrigerate. When ready to cook, bring the broth to a gentle simmer on the stovetop, then pour into the slow cooker and proceed from step 3.

Storage & reheating

Store leftover polenta in an airtight container in the refrigerator for up to 4 days. It will firm up as it cools. To reheat, add a splash of milk or broth and gently warm on the stovetop over medium-low heat, stirring often, until creamy again (about 5–10 minutes). Polenta does not freeze well due to texture changes.

Substitutions

sharp cheddar cheese, shredded → Gruyère, aged Gouda, or Pecorino Romano. Use a cheese with similar sharpness or richness. Pecorino will be saltier, so taste before adding extra salt.
vegetable broth → chicken broth or water. Chicken broth adds more savory depth; water yields a more neutral polenta that pairs well with rich toppings.
fresh flat-leaf parsley → fresh basil, chives, or sage. Basil adds a bright, peppery note; chives contribute onion flavor; sage brings earthiness. Use the same amount.
cornmeal (polenta) → polenta flour or corn grits (not instant). Standard polenta flour and grits work identically. Instant polenta will cook much faster (30–60 minutes) and may be grainier.
