Begin by preheating your oven to 425°F (220°C). Prepare a large baking sheet by lining it with parchment paper for easy cleanup.
In a medium-sized bowl, combine the smoked paprika, garlic powder, onion powder, ground cumin, salt, black pepper, and extra virgin olive oil. Stir well to form a flavorful spice paste.
Pat the pork tenderloin dry using paper towels to ensure a good sear. Generously rub the spice paste all over the tenderloin, making sure it is equally coated on all sides.
On the prepared baking sheet, artfully arrange the sliced red and yellow bell peppers, red onion wedges, and zucchini half-moons around the pork tenderloin, creating a colorful vegetable bed.
Drizzle a bit more extra virgin olive oil over the vegetables and toss them lightly to ensure they are evenly coated.
Position the seasoned pork tenderloin in the center of the vegetable arrangement on the baking sheet.
Roast everything in the preheated oven for 25-30 minutes, monitoring until the pork tenderloin reaches an internal temperature of 145°F (63°C). The vegetables will become tender and slightly caramelized, enhancing their natural sweetness.
Once cooked, remove the baking sheet from the oven and let the pork rest for about 5-10 minutes. This allows the juices to redistribute for a moister bite.
Slice the pork tenderloin into medallions and serve them next to the beautiful array of roasted vegetables. Garnish the dish with freshly chopped parsley for a pop of color and flavor.
Notes
Let the pork rest before slicing for juicier meat.
