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. You've likely tried to make them at home and ended up with a squeaky, water-logged pile of grey sadness. To capture that exact Spring Street magic, you have to respect the thermodynamics of the fungi. Mushrooms are sponges made of ninety percent water; throw them into hot butter, and they'll immediately boil themselves while the milk solids scorch into a bitter mess. The bistro secret is a patient, dry-pan evaporation phase to drive off the moisture, followed by a hard sear in oil, and finally a basting bath of premium cultured butter, shallots, and garlic.
Before you start
Organize your mise en place before the mushrooms ever hit the pan.
Once the internal water evaporates from the fungi, the cooking process moves aggressively fast. Have your minced shallots, garlic, measured butter, and vinegar sitting right next to the stove so you aren't scrambling while your pan burns.
Ingredients
- cremini or white button mushrooms1 lb
- kosher salt1/2 tsp
- grapeseed or canola oil1 tbsp
- cultured European-style butter3 tbsp
- shallots2 tbsp
- garlic cloves2 med
- Champagne vinegar1 tbsp
- flat-leaf parsley2 tbsp
- black pepper1/2 tsp
Method
- 01
Place a large cast-iron skillet over medium heat and add the mushrooms and a generous pinch of kosher salt to the dry pan.
Do not add oil or butter yet. The salt acts osmotically to help draw out the water. Cover the skillet with a lid and let them cook undisturbed for 4 to 5 minutes to collapse the air pockets.
- 02
Remove the lid, increase the heat to medium-high, and let the exuded liquid boil away completely.
Stir occasionally. Wait until every single drop of liquid has evaporated and the pan is bone-dry; this phase is absolutely mandatory before any browning can occur.
- 03
Add the neutral oil to the hot, dry pan, toss the mushrooms to coat, and spread them into a single even layer.
Leave them completely alone for at least two minutes to establish a hard sear against the cast iron, then toss and continue browning for another 3 to 4 minutes until deeply caramelized all over.
- 04
Reduce the heat to medium-low and add the cultured butter, shallots, and garlic.
Toss continuously for 1 to 2 minutes to baste the mushrooms in the foaming butter, stopping just before the garlic begins to brown and turn bitter.
- 05
Pour in the Champagne vinegar to deglaze the pan.
The acid will immediately sizzle and evaporate, scraping up the deeply flavored fond from the bottom of the skillet and coating the mushrooms in a glossy glaze.
- 06
Remove the skillet from the heat, stir in the freshly chopped parsley, and season aggressively with fresh black pepper.
Taste for salt, adjust if necessary, and serve immediately in a warmed dish alongside a perfectly rested steak frites.
Notes
Respect the physical limits of your pan.
A standard 12-inch cast-iron skillet can handle exactly one pound of mushrooms. If you pile them on top of each other, the steam released by the bottom layer will cook the top layer, creating a soggy mess. Work in batches if you scale up.
Execute the burnt butter rescue protocol immediately if your heat was too high.
If you add the cultured butter and the milk solids instantly blacken, there is no saving it. Dump the mushrooms into a colander to drain away the bitter, acrid fat, wipe the skillet totally clean, and return the mushrooms to the pan over low heat with a fresh knob of butter to re-glaze.
