Ingredients

  • 1 pound mushrooms (button mushrooms or mixed mushrooms like shiitake, morels, porcini, chanterelles - you need 20 to 25 button mushrooms or 5 cups sliced mixed mushrooms)

  • Salt
  • 4 beef filets (4 to 6 ounces each)

  • 3/4 cup red wine
  • 1 cup half-and-half
  • 1 cup whole milk
  • 1 bunch asparagus, tough ends trimmed
  • 6 ounces sliced bacon, pancetta or prosciutto (about 6 slices), chopped
  • 1 1/2 tablespoons white wine vinegar
  • Smashed Potatoes with Creme Fraiche, for serving, recipe follows
  • Fresh chopped parsley, for garnish
  • Special equipment: kitchen string or toothpicks
  • 2 pounds fingerling or small red potatoes
  • Salt
  • 1/3 cup unsalted butter
  • 4 cloves garlic, chopped
  • 2 shallots, chopped
  • Ground white pepper
  • 8 to 10 ounces creme fraiche or sour cream
  • 1/2 cup finely chopped chives
  • Zest of 1 lemon

Method

  • Preheat the oven to 375 degrees F.
  • With a paper towel, wipe all your mushrooms clean.
  • (Don't soak them in water and then drain them.
  • Mushrooms are like little sponges.
  • They'll suck up water and get mushy.)
  • Trim and discard the dried up part on the end of the mushroom stems.
  • Spread the mushrooms on a large sheet pan and drizzle with some olive oil.
  • Season with salt and toss to coat.
  • Roast the mushrooms for 30 to 45 minutes.
  • Using a paper towel, blot the filets and flank steak to remove excess moisture.
  • Sprinkle both sides of the beef with salt and pepper.
  • Rub the tops of the filets with 1 tablespoon of the chopped thyme.
  • Let the filets sit out, covered, to bring them up to room temperature before cooking.
  • Slice the flank steak lengthwise into 1-inch strips and wrap each filet around the edges with the flank steak strips.
  • You may have leftover flank steak.
  • Tie each filet with kitchen string, or insert a toothpick through to hold the flank steak to the filet.
  • When the mushrooms are roasted and nice and golden brown, remove from the oven, let cool a bit and then roughly chop.
  • Reduce the oven temperature to 350 degrees F.
  • In a large fry pan, heat 3 tablespoons of the butter on medium-high heat.
  • As soon as the butter starts to bubble and get frothy, throw in the roasted mushrooms and any oil and drippings from the baking sheet.
  • Saute the mushrooms for 8 to 10 minutes, and then deglaze the pan with the red wine.
  • Cook until most of the red wine has reduced to almost nothing.
  • Add the half-and-half to the pan while stirring the mushrooms.
  • Bring the mixture to a boil, and then lower the heat to a simmer and reduce by half.
  • Add the milk, and reduce that by one-third.
  • You should have nice rich sauce that coats the back of a spoon and holds a line through it.
  • Taste and adjust the seasoning if needed.
  • Keep the sauce warm until ready to serve.
  • (Can place it in a heatproof bowl set over a pot of gently simmering water.)
  • Wash the asparagus, and, with a vegetable peeler, remove the outer layer of asparagus.
  • Cut the asparagus into 2-inch pieces.
  • Heat a large fry pan with 1 teaspoon olive oil and add the bacon.
  • Stir and cook the bacon until it begins to brown.
  • Add the asparagus and cook until just softened.
  • Add the white wine vinegar and cook for a few seconds, and then remove from the heat and keep warm.
  • Heat a large ovenproof fry pan with 2 tablespoons olive oil over medium-high heat.
  • (If you have a really large frying pan you can put all 4 filets in the pan.
  • If you don't, cook in batches using 1 tablespoon of oil per batch.
  • You don't want the steaks to touch.
  • We want to get a nice sear on the outside of the filets and to achieve this, your filets need room.)
  • Add the filets to the hot pan and sear until your filet has relaxed to the point where it will let go of the pan, about 3 minutes on one side, and then flip.
  • Add a generous clump of butter to the hot pan and, when it's melted, tip the fry pan towards you so the butter pools in one spot.
  • Add the 3 full sprigs of thyme.
  • Now, with a large spoon, start basting your filets with the melted thyme flavored butter.
  • Flip the filets, baste each one again and transfer to the oven for a few minutes until just cooked through to medium.
  • To serve: Plate the Smashed Potatoes with Creme Fraiche just off to one side of the center of the plate.
  • Retrieve your filets from the oven and remove the string or toothpicks.
  • Lean a filet up against the potatoes.
  • Top with the mushroom gravy and place the asparagus in front of the filet.
  • Dust with the chopped parsley.
  • Wash the potatoes and place in a pot of salted water, enough to just cover the tops of the potatoes.
  • Bring to a boil, and then turn down to a simmer and cook until fork tender.
  • (When you stick a fork into the potato and it falls off with no resistance, they're done.)
  • Drain the potatoes and place on a tea towel or paper towel.
  • With the palm of your hand, lightly smash the potatoes so they just pop open a bit and split.
  • Make sure they kind of keep their shape.
  • In a large fry pan on medium heat, melt the butter and add the garlic, shallots, 1 teaspoon salt and 1/2 teaspoon white pepper.
  • When the garlic and shallots are translucent, add the smashed potatoes and toss so they all get kissed with the butter, shallots and garlic.
  • Heat for 5 minutes, and then add the creme fraiche to the pan with half the amount of chopped chives.
  • Toss so everything is nicely coated.
  • Serve family style or on individual plates and top with the rest of the chives and a little lemon zest.
  • The zest gives the spuds an extra little tang and zip.
