Mushroom-Blue Cheese Tenderloin

The week between Christmas and New Year, which is its own season — not winter exactly, more like a pause. Ryan was on shift for two of the days, off for the rest. The twins existed in pajamas. We ate leftovers in rotation: the rest of the apple cake, leftover pierogi reheated in butter, the half-pan of mom's green bean casserole that she made me take home in a foil tray with my name on it in Sharpie.

I made one real meal — a slow cooker pot roast with carrots and potatoes, the cheap chuck from Aldi that goes on sale right before New Year's because nobody is shopping for chuck on December twenty-ninth. I put it in at nine in the morning and forgot about it until two when the apartment started smelling like a place I would want to live in. Owen ate a piece of carrot the size of his fist and declared it a hot dog. I let him. Nora ate the meat and refused the vegetables on principle.

Wally came over on Tuesday with my dad. He's eighty-eight now and slower this winter. He sat in the living room chair while the twins climbed on him and he said "Myszka, get me a coffee," which he calls me even when I am sitting right there, even when he is asking me directly. He drank half the coffee and fell asleep with a twin on each leg. My dad and I watched from the kitchen and didn't say anything. There was nothing to say.

I didn't make resolutions. I did write down, in the back of Babcia Rose's notebook, three things I wanted: to finish the spring semester of the master's, to take the twins somewhere they'd remember even if they don't remember it, and to get through the year without Mom worrying out loud about me. Modest list. The kind of list a thirty-year-old special education teacher with toddler twins makes when she has done enough big things and just wants the small ones to hold.

The pot roast carried us through most of that week — it always does, that’s the whole point of it — but after five days of reheated everything, I wanted to actually cook something, something that required me to stand at the stove and pay attention for twenty minutes. This mushroom-blue cheese tenderloin is what I make when I want dinner to feel like a choice rather than a leftover. It’s fast enough for a Tuesday night and rich enough to feel like you meant it.

Prep Time: 10 min | Cook Time: 20 min | Total Time: 30 min | Servings: 4

Ingredients

4 beef tenderloin steaks (about 6 oz each, 1 inch thick)
1/2 teaspoon kosher salt
1/4 teaspoon black pepper
2 tablespoons butter, divided
1 tablespoon olive oil
8 oz cremini mushrooms, sliced
3 garlic cloves, minced
1/2 cup beef broth
1 teaspoon fresh thyme leaves (or 1/4 teaspoon dried)
1/2 cup blue cheese crumbles
1 tablespoon fresh parsley, chopped (optional, for serving)

Instructions

Season the steaks. Pat the tenderloin steaks dry with paper towels and season both sides evenly with salt and pepper. Let them sit at room temperature for 5–10 minutes while you prep the mushrooms.
Sear the beef. Heat 1 tablespoon butter and the olive oil in a large skillet over medium-high heat. Once the butter is foaming, add the steaks and sear 3–4 minutes per side for medium-rare, or until your preferred doneness. Transfer to a plate and tent loosely with foil.
Cook the mushrooms. Reduce heat to medium. Add the remaining 1 tablespoon butter to the same skillet. Add the sliced mushrooms and cook, stirring occasionally, for 5–6 minutes until they release their liquid and begin to brown. Add the minced garlic and thyme and cook 1 minute more.
Deglaze the pan. Pour in the beef broth, scraping up any browned bits from the bottom of the skillet. Simmer for 2–3 minutes until the liquid reduces by about half and the sauce thickens slightly.
Finish with blue cheese. Remove the pan from heat. Stir half the blue cheese crumbles into the mushroom sauce until just beginning to melt. Taste and adjust salt and pepper.
Plate and serve. Place each tenderloin on a plate, spoon the mushroom-blue cheese sauce over the top, and finish with the remaining blue cheese crumbles and parsley if using. Serve immediately.
