Grilled Hoisin Marinated Pork

Pork tenderloin is the cut that makes weeknight grilling work. It cooks fast, slices cleanly into rounds, and stays juicy even at the well-done end of the doneness spectrum. The challenge is getting flavor into the relatively mild meat, and that is where this hoisin marinade earns its keep.

The marinade leans on the deep, slightly sweet umami of hoisin sauce as the base. Hoisin is essentially the Chinese answer to barbecue sauce: a fermented soybean paste sweetened with sugar and seasoned with garlic, vinegar, and Chinese five-spice. A quarter cup of it gets a sharp acid lift from rice vinegar, salty depth from soy sauce, three cloves of fresh garlic for punch, and a teaspoon of toasted sesame oil for nuttiness.

Three to four hours of marinating is the sweet spot, with overnight giving even deeper flavor penetration. The salt in the soy and hoisin acts as a brine alongside flavoring the surface, which is why even a thin tenderloin reads juicy and seasoned all the way through.

The critical move on the grill is removing excess marinade before the pork hits the heat. The high sugar content in hoisin burns fast, and a thick coating turns into bitter char before the inside cooks. Wipe most of it off, then let the grill marks form on bare meat.

Pro Tips

• Use a meat thermometer. Pull the pork at 145°F (63°C) at the thickest spot for a rosy medium that the USDA now considers safe; carryover heat finishes the job during the rest.
• Let the grilled tenderloin rest 5 to 10 minutes tented with foil before slicing. Cutting too soon spills the juices on the board instead of leaving them in the meat.
• Slice across the grain into half-inch rounds. The fibers in tenderloin run long; cutting against them gives tender slices, with them gives chewy ones.
• Reserve a couple tablespoons of marinade BEFORE adding the pork (separate clean container) to brush on as a finishing glaze for the last 2 minutes on the grill.

Variations

• Add a tablespoon of grated fresh ginger to the marinade for a brighter, more pungent Asian profile.
• Stir in a teaspoon of sriracha or sambal oelek for a hot-and-sweet version that loves rice.
• Sub the pork tenderloin for boneless skinless chicken thighs and reduce the grilling time to 6 to 8 minutes per side.
