L'Etoile's Braised Cremini Mushrooms

This restaurant-style mushroom dish comes from L’Etoile, the legendary Madison, Wisconsin farm-to-table pioneer. Large cremini caps braise in reduced chicken stock, Madeira, and herbs, then get stuffed with a savory leek filling cooked down in the strained braising liquid, then topped with cheese and flashed under the broiler.

The technique is all about reduction and concentration. Four cups of chicken stock boil down to one cup before anything else happens, building a flavor base that could stand on its own. Madeira wine adds sweet, nutty complexity that dry white wine could never match. Braising the mushrooms stem-side up traps their own juices in the caps, mingling with the herbed liquid for 30 minutes of slow flavor exchange.

Straining and reducing that liquid again with sauteed leeks creates the filling. It’s technique-heavy but produces mushroom caps with layered, savory-sweet depth that a simple saute can’t touch.

Chef Tips

• Choose cremini caps that are closed and firm. Open gills mean the mushroom is past its prime and will turn mushy.
• Remove the stems cleanly with a small spoon. A gouge creates a wider cavity for stuffing.
• Reduce the stock patiently. Rushing it with high heat creates bitter flavor notes.
• Serve immediately after broiling. The filling firms up quickly once it starts cooling.

Variations

• Substitute dry sherry or Marsala for Madeira if you cannot find it.
• Add crumbled blue cheese or goat cheese to the filling instead of the broiled topping.
• Use portobello caps for a main-dish version rather than an appetizer.
