Apple-Smoked Smoked Fraldinha — Brazilian Bottom Sirloin
Fraldinha is the cut Americans call flank or bottom sirloin, and Brazilians treat it like gold. Loose grain, big beefy flavor, and it cooks fast. Reverse sear keeps it tender, and as long as you slice it right it's hard to ruin.

Method
- 10 min
Pat the fraldinha dry with paper towels. Trim off any silverskin but leave a thin layer of fat if present, especially on one side. Mix kosher salt, black pepper, and garlic powder. Drizzle the olive oil over the meat, then liberally apply the rub, ensuring good coverage on all sides. Gently press the rub into the meat.
Why it matters
Drying the meat helps the rub adhere better and promotes a better bark. The fat layer can render and add flavor and moisture during the cook.
Common mistake
Over-trimming all the fat or not patting the meat dry, which prevents a good bark from forming.
- 250°F15 min
Preheat your smoker or pellet grill to 250°F (120°C). Place your oak wood chunks in the firebox if using an offset, or ensure pellets are loaded. Insert a reliable probe thermometer into the thickest part of the fraldinha, ensuring it does not touch any bone or fat pockets.
Why it matters
Accurate temperature control is crucial for tender results, and preheating ensures the smoker maintains a consistent temperature when the meat goes in.
Common mistake
Not letting the smoker come to a stable temperature before adding the meat, leading to inconsistent cooking.
- 250°F45 min
Place the seasoned fraldinha directly on the grill grates. Close the lid and smoke until the internal temperature reaches 115-120°F (46-49°C). This typically takes about 30-45 minutes, depending on the thickness of your cut and smoker consistency.
Why it matters
Smoking at a lower temperature gently cooks the meat, allowing smoke flavor to penetrate without overcooking, setting the stage for a perfect reverse sear.
Common mistake
Smoking too long or at too high a temperature, which can dry out the meat before the sear.
- 450°F10 min
Once the fraldinha hits 115-120°F, remove it from the smoker and set it aside. Increase your smoker's temperature to its maximum setting (usually 450-500°F or higher), or preheat a cast iron skillet on high heat until it's screaming hot. If using a skillet, add butter.
Why it matters
A very hot searing surface is critical for developing a quick, flavorful crust (Maillard reaction) without cooking the interior much further.
Common mistake
Not getting the searing surface hot enough, which results in a gray, steamed crust rather than a deep brown, crispy one.
- 475°F6 min
Place the fraldinha on the hot grates or in the screaming hot cast iron skillet. Sear for 2-3 minutes per side, flipping often if needed, until a beautiful, deep brown crust forms and the internal temperature reaches your desired doneness (e.g., 130-135°F for medium-rare, 135-140°F for medium).
Why it matters
The high heat sear caramelizes the exterior, adding an incredible layer of flavor and texture that contrasts beautifully with the tender, smoky interior.
Common mistake
Over-searing or under-searing. Too much time on the hot surface can overcook the interior; too little results in a weak crust.
- 15 min
Remove the fraldinha from the heat immediately after searing. Transfer it to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes.
Why it matters
Resting allows the muscle fibers to relax and reabsorb juices that have been pushed to the center during cooking, ensuring a tender and moist final product.
Common mistake
Cutting into the meat too soon, causing all the delicious juices to spill out onto the cutting board.
- 5 min
After resting, identify the grain of the fraldinha. It runs at an angle and is quite coarse. Slice the meat against the grain into thin pieces, about 1/4 inch thick. Garnish with fresh chopped parsley if desired. Serve immediately.
Why it matters
Slicing against the grain shortens the muscle fibers, making the meat much more tender and enjoyable to chew. This is paramount for cuts like fraldinha.
Common mistake
Slicing with the grain, which results in tough, chewy pieces of meat, even if cooked perfectly.
