Preheat and prepare: Preheat your oven to 200°C (400°F). Line a 9x13 inch baking dish with aluminium foil for easy cleanup. This step saves you a scrub later.

Make the garlic herb crust: In a mixing bowl, combine the olive oil, minced garlic, parsley, rosemary, thyme, panko breadcrumbs, Parmesan cheese, salt, pepper, paprika, and onion powder. Stir until everything is well coated and the mixture looks like a coarse, damp, golden-green sand.

Prepare the pork: Pat the pork tenderloins dry with kitchen paper. This is crucial – any moisture on the surface will prevent the crust from sticking and crisping up. The meat should feel dry to the touch.

Coat the tenderloins: Using your hands, press the herb and breadcrumb mixture firmly onto all sides of each tenderloin. Don't be shy – you want a thick, even coating. The crust should feel compact and slightly sticky as you apply it.

Bake to perfection: Place the coated tenderloins in the prepared baking dish. Bake for 25-30 minutes. After 15 minutes, you'll hear a gentle sizzling sound as the crust begins to brown. At the 25-minute mark, the top should be a deep golden brown and feel firm to a gentle touch. The internal temperature should reach 63°C (145°F) when checked with a meat thermometer.

Rest before slicing: Remove the baking dish from the oven and tent it loosely with foil. Let the pork rest for 10 minutes. This is not a step to skip – the juices will redistribute throughout the meat, and you'll see them settling as the tenderloin relaxes. The crust will stay crisp, and the meat will be wonderfully tender.

Slice and serve: Transfer the rested tenderloin to a cutting board. Using a sharp knife, slice into medallions about 2-3 cm thick. You should see a pale, juicy interior with a crisp, golden-brown edge. Serve immediately.
