Steps
Before you start
- Cut leeks in half lengthwise and rinse thoroughly between layers to remove any grit
- Have all ingredients measured and ready—polenta requires constant attention once liquid is added
- Use a whisk to avoid lumps when adding polenta to hot broth
Braise the leeks
- In a large heavy-bottomed saucepan, melt 1 tablespoon (15 g) of butter over medium heat.
- Add the sliced leeks and a pinch of salt.
- Stir to coat, then cover and cook for 8–10 minutes, stirring occasionally, until the leeks soften and begin to release their moisture.
- They should be tender and lightly golden at the edges.

Ready when: Leeks are translucent and tender, edges lightly golden
Tip: Don't rush this step—slow cooking develops the leeks' sweetness and creamy texture.
Add broth and aromatics
- Pour the chicken broth into the saucepan with the leeks.
- Add the fresh thyme sprigs and bay leaf.
- Increase heat to medium-high and bring to a gentle boil, stirring occasionally.
- Once steaming, reduce heat to medium and maintain a steady simmer.

Ready when: Broth bubbles gently at the surface
Tip: Keep broth at a gentle simmer, not a rolling boil, so the polenta cooks evenly.
Whisk in polenta
- Slowly pour the polenta into the simmering broth while whisking constantly to prevent lumps from forming.
- Whisk for about 2 minutes until the polenta is fully incorporated and the mixture is smooth.
- The polenta will thicken the broth noticeably.

Ready when: Mixture is smooth and evenly thickened with no visible lumps
Tip: Add polenta slowly and whisk continuously—this is the most critical step for avoiding lumps.
Simmer polenta and leeks together
- Reduce heat to medium-low.
- Simmer uncovered, stirring frequently with a wooden spoon, for 20–25 minutes, until the polenta is tender and creamy and has absorbed most of the broth.
- The mixture should move slowly when you drag a spoon through it; it should not be soupy.
- Stir every 2–3 minutes to prevent sticking and burning on the bottom.

Ready when: Polenta is creamy and tender, holds its shape briefly on a spoon, leeks are fully soft
Tip: Keep the heat low and stir often to prevent the bottom from scorching. The polenta will thicken as it cooks.
Remove herbs and finish
- Fish out and discard the thyme sprigs and bay leaf using a fork or slotted spoon.
- Remove the pan from heat.
- Stir in the crème fraîche and the remaining 1 tablespoon (15 g) of butter until fully incorporated.
- The mixture should be silky and creamy.
- Taste and season with kosher salt and freshly ground black pepper to your preference.

Ready when: Crème fraîche is fully incorporated, no streaks visible; mixture is smooth and luxurious
Tip: Add crème fraîche off heat so it doesn't break or curdle. Ensure it's at room temperature before stirring in.
Rest and serve
- Let the polenta rice rest, covered, for 2–3 minutes.
- This allows it to set slightly and become creamier.
- Divide among warm bowls or plates.
- Garnish with grated Parmigiano-Reggiano and a few fresh thyme leaves if desired.
- Serve immediately.

Ready when: Polenta has a cohesive, creamy consistency
Tip: Serve right away—polenta continues to firm up as it cools, and reheating can make it gluey.
Good to know
Tips
- This dish pairs beautifully with roasted chicken, duck, or firm white fish. It also works as a vegetarian side for roasted vegetables.
- For a richer version, stir in an extra 2 tablespoons (30 g) of butter along with the crème fraîche, or finish with a knob of truffle butter.
- If your polenta thickens too much, thin it with a small splash of warmed chicken broth or cream stirred in gently off heat.
- The quality of your chicken broth matters here—use homemade or a good-quality store-bought broth, as it will directly flavor the finished dish.
Storage & reheating
Best served fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, place in a saucepan over medium heat with a splash of chicken broth or cream, stirring constantly until warmed through and loosened to a creamy consistency. Do not freeze.
Substitutions
- crème fraîche or sour cream → heavy cream or crème fraîche. Use equal amount. Heavy cream will be slightly less tangy but equally creamy.
- fresh thyme sprigs → fresh sage or a mix of fresh herbs (tarragon, parsley, or chervil). Use the same amount. Sage will add a more assertive, slightly peppery flavor.
- polenta (cornmeal), coarse or medium grind → arborio rice or carnaroli rice (risotto rice). Use the same amount. Reduce cooking time to 18–20 minutes and stir more frequently. Result will be creamier.
- chicken broth, preferably homemade → vegetable broth or unsalted vegetable stock. Use equal amount. Omit the bay leaf and add 2–3 additional thyme sprigs for depth.
