Ingredients
- 4large portobello mushrooms, stems and gills removed with a spoon
- ¼cup olive oil
- 2teaspoons coarsely ground black pepper
- 4tablespoons unsalted butter, plus more as needed
- 3garlic cloves, coarsely chopped
- Kosher salt
- 1shallot, finely chopped
- ¼cup Cognac or another brandy
- ¾cup heavy cream
- 1tablespoon Dijon mustard
Preparation
- Step 1
Brush the mushrooms all over with olive oil. Sprinkle the pepper evenly over the gill sides (about ½ teaspoon per mushroom). Heat a large cast-iron skillet over medium-high, then add the mushrooms gill side up and sear until the underside is browned and the gill side looks wet, 3 to 6 minutes. Flip and cook until golden and the pepper is fragrant, 2 to 4 minutes.
- Step 2
Reduce heat to medium-low. Flip the mushrooms so they’re gill side up, then add the butter and garlic, and season with salt. While stirring the garlic to keep it from scorching, tilt the skillet to spoon up the melting butter and baste the mushrooms until tender, 2 to 5 minutes. Transfer the mushrooms to a plate, leaving the butter in the skillet.
- Step 3
Add the shallot and stir until softened, 2 to 4 minutes, adding a little more butter if the pan is dry. Stand back, and carefully add the Cognac. (It might flame.) Stir until the Cognac has nearly evaporated. Add the heavy cream and mustard, season with salt, and stir to combine. Return the mushrooms to the pan gill side down, and cook until the cream is thickened and the color of a latte, 2 to 4 minutes. Eat the mushrooms with a drizzle of the sauce.

Any suggestions for a substitution for the heavy cream so this can be a vegan dish?
For those who can’t do heavy cream I find that unsweetened original “NutPod” works so well. It’s a blend of cashew and coconut so it doesn’t have a coconut flavor and I use it whenever I make cream pasta etc.
Any liquid will deglaze the pan. Cognac is distilled from wine, fermented from grapes. The flavor you would get from bourbon will be quite different, bourbon being distilled from corn (at least 51% corn, but usually much more). You could just as well deglaze with white wine, or even stock. Beef stock would flavor well with the cream and mustard but if keeping vegetarian, veggie stock would work fine.
This is great! My husband, Jason likes it better than Steak au Poivre (say what?)! I recommend frying up some sweet Vidalia onions on the side. Jason wants me to double the sauce next time. Scrumptious!
I used less butter and 1/2 & 1/2 and it was still delicious!
This was delicious! I made them into steak sandwiches. I subbed onions for shallots because that's what I had on hand. I didn't have cognac so I used bourbon because I thought the sweetness would complement the mushrooms. Also, used half and half because I rarely buy heavy cream. Served with baked potatoes because I was tired and they are easy. Next time, I will skip the ciabatta roll a serve atop the baked potatoes. This is a deeply satisfying meal!
