A few things worth knowing
- Spread the beef and mushrooms in a single layer with space between pieces so they roast instead of steaming.
- Pat the beef cubes dry with paper towels before tossing with oil for better exterior browning.
- Add the chimichurri sauce immediately after removing the pan from the oven so the residual heat warms the herbs and releases their fragrance.
- Keep the mushroom halves roughly the same size as the beef cubes for uniform cooking.
Ways to make it your own
- Garnish with additional fresh flat-leaf parsley or finely chopped oregano before serving.
- Serve over steamed white rice or cauliflower rice to catch the excess chimichurri juices.
Serving suggestions
Serve this hot from the pan alongside roasted baby potatoes, warm grain bowls, or a simple leafy salad tossed in a light vinaigrette. Crusty artisan bread is also wonderful for catching any leftover chimichurri and pan drippings.
Storage & reheating
Transfer any leftover beef and mushrooms to an airtight container and refrigerate promptly. Reheat gently in a warm skillet or oven just until warmed through to prevent the sirloin from toughening.

Quick recipe answers
Why add the chimichurri after roasting instead of before?+
Cooking chimichurri in a hot oven can scorch the delicate fresh herbs and mute the bright acidity of the vinegar. Drizzling it over the warm roasted beef preserves its fresh punch.
Can I use whole mushrooms instead of halved?+
If your mushrooms are very small, you can leave them whole. Larger creminis should be halved or quartered so they finish roasting in the same 15-minute window as the sirloin cubes.
With tender sirloin, earthy creminis, and a generous pour of chimichurri, this simple sheet-pan dinner delivers bold steakhouse flavor with minimal evening effort.
