Steak au Poivre with Creamy Peppercorn Sauce & Mashed Potatoes

Steak au Poivre is one of those dishes that instantly makes dinner feel like an occasion. It’s cozy and classic, but with just enough drama—thanks to that bold peppercorn crust and the silky, cream-swirled sauce that tastes like it came straight from a little French bistro. Add a pile of buttery mashed potatoes on the side, and suddenly the whole table feels warmer.

This is the meal I love making on a slower evening—date night at home, a small celebration, or whenever you want something comforting that still feels a bit “wow.” The steak sizzles as it hits the pan, the kitchen smells like toasted pepper and butter, and that peppercorn sauce… it’s rich, savory, and just a little punchy in the best way.

Ingredients

For the Steak au Poivre

• 2 beef tenderloin steaks (6–8 oz each)

• 1 tablespoon whole black peppercorns, coarsely crushed

• Salt, to taste

• 1 tablespoon olive oil

• 1 tablespoon butter

For the Peppercorn Sauce

• 1/4 cup finely chopped shallots

• 1/2 cup beef broth

• 1/4 cup brandy or cognac (for deglazing)

• 1/2 cup heavy cream

• 1 tablespoon Dijon mustard (optional)

• 1 tablespoon unsalted butter (for finishing)

• Salt and pepper, to taste

For the Mashed Potatoes

• 1 ½ pounds Yukon gold or russet potatoes, peeled and cubed

• 1/2 cup whole milk, warmed

• 1/4 cup unsalted butter

• Salt and freshly ground black pepper, to taste

Instructions

1. Cook the potatoes
Bring a large pot of salted water to a boil. Add the potatoes and cook until fork-tender, about 15 minutes. Drain well, then mash until smooth. Stir in the warm milk and butter. Season with salt and pepper. Cover and keep warm while you cook the steak.

2. Prep the steaks
Pat the steaks dry with paper towels (this helps you get that gorgeous sear). Season generously with salt, then press the crushed peppercorns firmly onto both sides. Let the steaks sit at room temperature for about 15–20 minutes so they cook more evenly.

3. Sear the steaks
Heat the olive oil and butter in a skillet over medium-high heat. When the butter starts to foam, add the steaks. Sear for about 3–4 minutes per side for medium-rare, depending on thickness. Once they’re beautifully browned, transfer to a plate and let them rest.

4. Build the peppercorn sauce
Lower the heat to medium. In the same skillet (don’t wipe it out—those browned bits are gold), add the shallots. Sauté for 1–2 minutes until softened and fragrant.

Carefully pour in the brandy or cognac to deglaze. Scrape up all the flavorful bits from the bottom of the pan. Let it simmer until the alcohol cooks off.

Add the beef broth and simmer for 2–3 minutes. Then stir in the heavy cream and Dijon mustard if you’re using it. Let the sauce gently bubble until it thickens, about 4–5 minutes. Finish with the tablespoon of butter and season to taste.

5. Serve
Slice the rested steak and spoon that warm, creamy peppercorn sauce over the top. Plate it with a generous scoop of mashed potatoes, and finish with a sprinkle of chopped parsley or thyme.

Presentation

• Spoon a little sauce onto the plate first, then lay the sliced steak on top for that “restaurant” look.

• Add a small mound of mashed potatoes and give them a swoosh with the back of a spoon for a pretty shape.

• A pinch of chopped herbs adds fresh color, and a few extra cracked peppercorns on top make it look extra intentional.

• If you want a complete plate, a simple green salad or roasted asparagus pairs perfectly and keeps things balanced.
