Chapter 3 — The Sides
At Balthazar, a side of sautéed mushrooms arrives in a small, searing-hot dish, radiating the smell of toasted butter, garlic, and earth. It tastes profound. You’ve likely tried to make them at home and ended up with a grey, water-logged pile. The difference between the home-cook simplification and the brasserie standard comes down to thermodynamics and the quality of your fat. First, we dry-cook the fungi to aggressively evaporate their internal water. Only when the pan is bone-dry do we introduce a high-smoke-point oil to trigger the Maillard browning. Finish with a bath of premium cultured butter, shallots, garlic, and a sharp hit of Champagne vinegar, and you will taste exactly what Spring Street tastes like.
Before you start
If cooking for a dinner party, the mushrooms can be taken through the high-heat searing phase hours in advance.
Hold them at room temperature, then reheat gently and execute the butter, shallot, and vinegar finish just before the plates go to the table.
Ingredients
- cremini mushrooms1 lb
- kosher salt1/2 tsp
- grapeseed oil1 tbsp
- cultured French butter3 tbsp
- shallot2 tbsp
- garlic cloves2 small
- Champagne vinegar1 tbsp
- flat-leaf parsley2 tbsp
- black pepper1/4 tsp
Method
- 01
Place a large cast-iron skillet over medium heat and add the dry mushrooms with a generous pinch of kosher salt.
Cover the skillet with a lid and let them cook undisturbed for 4 to 5 minutes so the heat collapses their internal air pockets and draws out the liquid.
- 02
Remove the lid, increase the heat to medium-high, and boil off the released liquid.
Stir occasionally and wait until every single drop of liquid has evaporated; the pan must be bone-dry before proceeding to achieve a proper sear.
- 03
Add the grapeseed oil to the hot, dry pan and toss the mushrooms to coat.
Spread them into a single, even layer and leave them entirely alone for at least 2 minutes. This undisturbed contact with the cast iron creates the deep, golden-brown crust.
- 04
Toss the mushrooms and continue sautéing for another 3 to 4 minutes until deeply browned all over.
- 05
Drop the heat to medium-low and add the cultured butter.
Do not rush this transition; if the pan remains at searing heat, the milk solids will instantly scorch and turn acrid.
- 06
Immediately add the minced shallots and garlic, tossing continuously to baste the mushrooms in the foaming, nutty butter.
Cook for exactly 1 to 2 minutes, just until the shallots turn translucent and the garlic is highly fragrant but not brown.
- 07
Deglaze the pan with the Champagne vinegar.
It will sizzle and evaporate immediately, lifting the deeply flavored fond from the bottom of the cast iron and coating the mushrooms in a glossy glaze.
- 08
Remove from the heat, stir in the fresh parsley, and adjust seasoning with salt and a heavy grating of black pepper before serving immediately.
Notes
Sogginess rescue protocol.
If your mushrooms are stewing in a massive puddle that refuses to evaporate, remove them with a slotted spoon. Pour off the liquid (save it for gravy), wipe the skillet bone-dry, return it to high heat, add the oil, and force the sear.
Burnt butter rescue protocol.
If your pan was too hot and the butter turns black and acrid, immediately dump the mushrooms into a colander to drain away the burnt fat. Wipe the skillet clean, return to low heat, and start the glazing process over with fresh butter. You cannot hide the taste of scorched milk solids.
Do not overcrowd your pan.
If you only have a 10-inch skillet, you must cook the mushrooms in two batches during the searing phase. Piling them high guarantees a steam-bath, not a sauté.
