Directions

1
Using a sharp knife, pierce the sirloin all over to help the seasonings penetrate deeply into the meat.
2
Combine minced garlic, salt, pepper and chopped parsley into a paste. Rub it thoroughly over the entire surface of the meat and let it rest for 10 minutes.
3
Place half the onion rounds in an even layer on the bottom of the pressure cooker. Crumble 1 bouillon cube over them.
4
Set the sirloin on top of the onion bed, cover with the remaining onions, crumble the second bouillon cube and lay the thyme sprig on top.
5
Pour in the cold water, seal the pressure cooker lid and bring to full pressure over medium-high heat.
6
Once the valve starts releasing steam, reduce to medium heat and cook for 30 minutes. Release pressure naturally before opening.
7
Remove the sirloin and slice it into thick cuts. Return the pot to high heat without the lid and reduce the cooking juices for 5 minutes into a glossy sauce.
8
Season with additional salt and pepper if needed, then spoon the onion sauce generously over the sliced beef.
9
Serve immediately with steamed white rice or mashed potatoes.

💡 Chef's Tip

For deeper flavor, marinate the meat overnight with the garlic-herb rub. A splash of dry red wine added before sealing the cooker adds a wonderful richness to the sauce.
