Recipe Shopping List

Here’s what you’ll need to make this roast. For exact amounts, see the ingredient list in the recipe card below.

• Sirloin Cap Roast – Also known as coulotte or picanha. Choose a roast with a good fat cap when possible.
• Smoked Salt – Adds depth and a subtle smoky note that complements the grill smoke.
• Cracked Peppercorn Medley – A mix of peppercorns gives balanced heat and aromatic complexity.

If you prefer a single seasoning blend, a simple mix of smoked salt, coarse pepper, and garlic (often called SPG or steak seasoning) works beautifully on this roast.

How To Make This Roast

This overview shows the main steps. Refer to the recipe card below for exact weights and ingredient amounts when you cook.

1. Preheat the Pellet Grill – Bring the smoker to 225°F for a gentle, even smoke that promotes an even cook and a good smoke ring.
2. Season Generously – Pat the roast dry, then coat all sides with smoked salt, granulated garlic, and cracked pepper. Allow the seasoning to adhere for a few minutes before placing on the grill.
3. Smoke Fat-Side Up – Place the roast fat-side up so rendered fat bastes the meat while it cooks. Plan on roughly an hour, but rely on internal temperature rather than time.
4. Monitor Internal Temperature – Use an instant-read thermometer and pull the roast at your preferred pull temperature from the included chart (rare through well).
5. Rest and Slice Thin – Tent the roast with foil and rest for 10 minutes. Slice thinly across the grain for the most tender bites.
