Pan-Seared Pork Medallions with Warm Balsamic-Glazed Radicchio

Cut the radicchio head into 8 wedges, keeping the core intact so the leaves hold together during cooking.

Submerge the radicchio wedges in a large bowl of ice water for 15 minutes. This process leaches out the water-soluble bitter compounds (intybin) while the thermal shock contracts the cell walls to maximize crispness.

Remove the radicchio from the ice bath, drain thoroughly, and pat completely dry with paper towels.

Trim the pork tenderloin and cut into 1-inch thick medallions. Pat dry and season both sides with salt, black pepper, and chopped rosemary.

In a large skillet over medium-high heat, add 1 tablespoon of olive oil. Sear the pork medallions for 3 to 4 minutes per side until golden brown and cooked to an internal temperature of 145 degrees F. Transfer to a plate and tent with foil to rest.

Reduce the skillet heat to medium. Add the remaining olive oil and the diced pancetta. Cook until the pancetta is crisp and golden, about 4 to 5 minutes. Use a slotted spoon to transfer the pancetta to the plate with the pork, leaving the rendered fat in the skillet.

Add the sliced garlic to the skillet and cook for 1 minute until fragrant. Add the dried radicchio wedges in a single layer. Sear for 2 minutes per side until the edges are caramelized but the center remains slightly firm.

Drizzle the balsamic vinegar and honey over the radicchio in the skillet. Toss gently for 1 minute to coat and let the glaze reduce slightly.

Plate the warm balsamic-glazed radicchio alongside the rested pork medallions. Spoon the remaining pan glaze and crispy pancetta over the top. Garnish with toasted walnuts and shaved Parmesan cheese.
