2 garlic cloves
0.85 cup beef broth
2 1/10 oz crème fraîche
1 tsp Dijon mustard

Jacket Potato

2 large baking potatoes

a splash oil
to taste caramelised onions
0.53 oz garlic butter

Roasted Broccoli

7 1/10 oz tenderstem broccoli

1 lemon
to taste Parmesan cheese

Instructions

1
Pre‑heat the oven to 392°F and start baking the jacket potatoes as described in the Jacket Potato component.
2
While the potatoes bake, heat a non‑stick skillet over medium‑low heat, add a splash of water and the thinly sliced onions; cook slowly for 10–15 minutes until softened.
3
Stir in 1 tsp balsamic vinegar and 1 tsp honey, continue cooking for another 5 minutes until the onions become sticky and caramelised. Transfer the onions to a bowl, leaving the pan on the stove.
4
Using the same pan, lightly crush the black peppercorns, then add the chopped shallot and minced garlic with a splash of beef broth; sauté for 3 minutes.
5
Add the crushed peppercorns and cook for 1 minute, then pour in enough beef broth to reach 200 ml total. Simmer for 5 minutes, reducing the liquid by half.
6
Lower the heat, stir in the crème fraîche and Dijon mustard, and gently warm for 2–3 minutes until the sauce thickens. Keep the sauce warm while you finish the steaks.
7
Season the sirloin steaks generously with salt and freshly ground black pepper. In a hot skillet, sear the steaks 2–3 minutes per side for medium‑rare, turning once.
8
During the last 30 seconds of cooking, add the 15 g garlic butter and rosemary to the pan; baste the steaks with the melted butter, then remove the steaks and let them rest for 5 minutes.
9
While the steaks rest, finish the peppercorn sauce by whisking in any pan juices and the remaining butter from the steak pan.
10
Plate the rested steaks, spoon the peppercorn sauce over them, serve the jacket potatoes topped with caramelised onions and garlic butter, and place the roasted broccoli on the side.

Helpful tips while cooking

Timing the potatoes

Start the oven‑baked potatoes first, as they need a full hour before the other components are ready.

Caramelising the onions

Cook the thinly sliced onions low and slow for 10–15 minutes, then add balsamic and honey for the final 5 minutes.

Basting the steaks

Add the garlic butter and rosemary during the last 30 seconds of searing, then rest the steaks for 5 minutes before serving.

Finishing the peppercorn sauce

After the steaks rest, whisk the pan juices and any remaining butter into the simmered sauce to finish it.
