Grilled Beef Steak with Mushroom-Cheese Jus, Duchess Potato, and Bacon-Wrapped Garnish

Headnote

This dish is built on contrast: the direct flavor of grilled beef, the richness of melted cheese, the earthiness of mushrooms, and the disciplined sweetness of duchess potato. Bacon is used as a precise accent, not a disguise, lending salt and smoke to the plate. The result should feel composed, substantial, and exact, with each element retaining its own identity.

Ingredients

Beef and mushrooms

320 g beef steak

120 g mushroom, sliced

40 g cheese, finely grated

12 g vegetable oil

4 g salt

2 g black pepper

Duchess potato

180 g potato, peeled and cut into even pieces

20 g butter

20 g cream

2 g salt

1 g black pepper

Bacon-wrapped garnish

40 g bacon

40 g tomato, cut into neat wedges

10 g microgreen

Method

1. Heat the oven to 210°C. Line a baking tray with parchment if needed. Bring a saucepan of salted water to a boil for the potato.

2. Place the potato in the boiling water and cook for 14 to 16 minutes, until completely tender and the edges begin to break when pressed. Drain well, then return to the warm pan for 1 minute to drive off excess moisture.

3. Pass the potato through a ricer or mash it finely. Work in the butter, then the cream, then season with salt and black pepper. The mixture must be smooth, dry enough to hold a piped shape, and free of lumps. Transfer to a piping bag fitted with a large star nozzle.

4. Wrap the bacon around the tomato wedges so that each piece is lightly secured but not compressed. Place on the tray and bake for 10 to 12 minutes, until rendered and lightly crisp at the edges. Hold warm.

5. Season the beef steak evenly with salt and black pepper. Heat the vegetable oil in a heavy skillet or grill pan over high heat until the surface shimmers. Sear the steak for 2 to 4 minutes per side, depending on thickness, until deeply browned. For medium-rare, the internal temperature should reach 52 to 54°C. Transfer to a warm plate and rest for 5 minutes.

6. In the same pan, add the mushrooms and cook over high heat for 4 to 5 minutes, stirring only as needed, until they release their moisture and then begin to color. Add the cheese and allow it to melt into the mushrooms, forming a glossy, clinging mixture. The texture should be supple, not greasy.

7. Pipe the duchess potato onto the tray in two neat rosettes or elongated swirls. Bake for 8 to 10 minutes at 210°C, until the edges are lightly golden and the surface is set with a faint crust.

8. Rewarm the steak briefly if necessary, then place it on the plate beside the mushroom-cheese mixture. Keep the meat juicy and the mushrooms glossy.

Plating and serving

Place the steak slightly off center. Spoon the mushroom-cheese mixture alongside, not over the meat. Set the duchess potato with height and clean definition, then arrange the bacon-wrapped tomato garnish to provide color and contrast. Finish with microgreen placed lightly at the end, so the plate reads as composed and deliberate.

Professional notes

Do not overcook the mushrooms; they should remain distinct beneath the melted cheese. The duchess potato must be dry before piping, or it will lose its shape in the oven. Resting the steak is essential: the meat should slice cleanly and remain moist, with clear juices and a resilient, tender bite.
