Rich Mushroom Ragu

This sauce relies on patience rather than complexity. When the mushrooms stop steaming and begin to fry in the pan, they concentrate into a base that provides the structure for the entire meal.

Before you start

Commit to the browning process.

If you crowd the pan or stop cooking before the mushrooms turn dark brown, the sauce will be watery and lack depth. Take the time to drive the liquid out early.

The key technique

Driving out the moisture

Keep the heat high until the mushrooms sizzle rather than steam. You are looking for a dark, mahogany color on the bottom of the pan before adding aromatics.

Step by step

The method.

  1. Prepare the mushrooms

    Pulse the mushrooms in a food processor or mince by hand until they resemble the texture of coarse ground meat.

  2. Brown the base

    Heat olive oil in a heavy skillet over medium-high heat. Add the mushrooms and cook, stirring occasionally, until the liquid has evaporated and the mushrooms are browned and beginning to stick to the bottom.

  3. Aromatics

    Add the onion to the pan. Cook until translucent. Stir in the garlic and tomato paste, cooking for 2 minutes until the paste darkens slightly.

  4. Deglaze

    Pour in the wine. Scrape the brown bits off the bottom of the pan with your spoon. Let it simmer until the wine has almost fully evaporated.

  5. Simmer

    Pour in the stock and add the thyme. Reduce heat to low and simmer for 15-20 minutes until the liquid has reduced into a thick, clinging sauce. Season with salt and pepper.

Variations

Other turns to take.

Creamy finish

Stir in a tablespoon of heavy cream or butter at the very end to round out the sharpness of the wine.

Dried mushroom boost

Rehydrate an ounce of dried porcini mushrooms in hot water; chop them and add them to the pan along with the strained soaking liquid for an intense earthiness.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use a wide pan to ensure the mushrooms have enough surface area to brown quickly.

Tip

Do not salt the mushrooms until they have browned; salt draws out water and will stall the browning process.

Tip

Serve over wide, flat pasta like pappardelle or tagliatelle to hold the texture.

Questions

The ones that keep coming up.

Can I use button mushrooms?

You can, but they have a higher water content and less flavor. If using them, increase the browning time to ensure you get a deep color.

What if I don't want to use wine?

Substitute the wine with an extra splash of stock and a teaspoon of balsamic vinegar to provide the necessary acidity.
