Chestnut and Wild Mushroom Ragù

Steps

1. 1

   Prepare ingredients

   • Dice the medium onion into ¼-inch pieces.
   • Mince the garlic.
   • Clean the mushrooms with a damp cloth and halve or quarter them depending on size to create roughly uniform pieces so they cook evenly—this is important for even cooking and browning.
   • Measure out the tomato paste, stock, and other ingredients so everything is ready (mise en place).
   • Having everything prepped before you start cooking makes the process smooth and prevents burning or overcooking any component while gathering the next ingredient.

   Ready when: Ingredients are prepped and measured out; mushrooms are uniform in size

   Tip: Setting up mise en place—preparing and measuring everything before you start—prevents scrambling and ensures nothing burns while you're gathering the next ingredient.

2. 2

   Sear the mushrooms

   • Heat 2 tablespoons of the olive oil in a large heavy-bottomed pot (5–6 quart capacity) over medium-high heat until the oil shimmers, about 1 minute.
   • Add the prepared mushrooms in a single layer.
   • Let them sit undisturbed for 3–4 minutes—resist the urge to stir immediately.
   • After 3–4 minutes, stir and continue cooking for another 4–5 minutes until the mushrooms are golden brown and caramelized.
   • Most of their liquid should have evaporated, and they should smell deeply savory and rich.
   • Transfer the mushrooms to a clean plate.

   Ready when: Mushrooms are golden brown and caramelized; most liquid has evaporated; smell deeply savory

   Tip: Don't stir immediately—let the mushrooms develop a golden crust first, which builds umami depth. If crowded, sear in batches rather than piling them on top of each other, which steams them instead of browning them.

3. 3

   Build the flavor base

   • Add the remaining 1 tablespoon of olive oil to the pot, then add the diced onion.
   • Cook over medium heat, stirring occasionally, for about 3 minutes until the onion begins to soften and turn translucent.
   • Add the minced garlic and cook for 1 minute until fragrant and the raw smell dissipates.
   • Stir in the tomato paste and cook for another minute, stirring constantly to prevent sticking.
   • The tomato paste should darken slightly and smell concentrated and sweet.

   Ready when: Onion is translucent; tomato paste is darkened and fragrant

   Tip: Cooking the tomato paste briefly before adding liquids helps concentrate and deepen its flavor, adding richness to the final sauce without any tinned taste.

4. 4

   Deglaze with wine (optional)

   • If using red wine, pour the ½ cup into the pot and scrape the bottom with a wooden spoon to dislodge any browned bits stuck to the pot—this is where intense flavor hides.
   • Let the wine simmer for 1–2 minutes to cook off some of the alcohol and reduce slightly.
   • If you're not using wine, skip this step and proceed to step 5.

   Ready when: Wine has reduced slightly and the raw alcohol smell has mostly dissipated

   Tip: This step isn't essential but the wine adds subtle complexity and acidity that balance the sauce beautifully. Skip only if you strongly prefer to avoid alcohol.

5. 5

   Add remaining ingredients

   • Return the seared mushrooms to the pot.
   • Add the canned crushed tomatoes (with their juices), vegetable stock, bay leaves, dried thyme, and roasted chestnuts.
   • Stir everything together until well combined, then turn the heat up to medium-high to bring the sauce to a gentle simmer.

   Ready when: Sauce is simmering gently with small bubbles regularly breaking the surface

6. 6

   Simmer and braise the ragù

   • Once the sauce reaches a simmer, reduce the heat to medium-low and let it simmer uncovered for 30–35 minutes.
   • Stir occasionally—every 5–7 minutes—to prevent sticking on the bottom.
   • The sauce should gradually reduce and thicken.
   • The tomatoes will completely break down into the sauce, the vegetables will become tender, and the flavors will meld together into something much greater than the sum of its parts.
   • The chestnuts should be tender when pierced with a fork.
   • The sauce is ready when it is thick enough to coat the back of a spoon; if too thin, continue simmering a few more minutes; if too thick, stir in a splash of warm vegetable stock or water.

   Ready when: Sauce coats the back of a spoon; tomatoes have completely broken down; vegetables are tender; chestnuts are tender when pierced with a fork

   Tip: Stir occasionally to prevent sticking on the bottom, but don't over-stir—you want the flavors to concentrate. The sauce will continue to thicken slightly as it cools, so don't over-reduce it on the stovetop.

7. 7

   Season to taste

   • Remove the bay leaves with a slotted spoon or fork and discard them.
   • Taste the ragù carefully.
   • Season generously with kosher salt and freshly ground black pepper.
   • Start with ½ teaspoon of salt and adjust from there, as you can always add more but can't remove it.
   • The sauce should taste rich and well-balanced, with the earthiness of mushrooms and chestnuts, the acidity from tomatoes, and the herbal notes from thyme melding together into a savory whole.

   Ready when: Flavors are well-balanced and taste delicious; salt and pepper bring all flavors into focus

   Tip: Taste critically. The sauce should have deep umami from the mushrooms, sweetness and acidity from tomatoes, and earthy notes from chestnuts and herbs. Salt amplifies these flavors.

8. 8

   Serve with pasta or polenta

   • Ladle the hot ragù over cooked pasta—pappardelle (wide ribbons) or thick spaghetti work beautifully to catch the sauce.
   • Alternatively, serve over creamy polenta or as a sauce for roasted vegetables.
   • Top each serving with freshly grated Parmigiano-Reggiano and a small handful of chopped fresh parsley if desired.
   • Finish with a drizzle of excellent extra virgin olive oil.
   • Serve immediately while hot.
