Lean pork loin with roasted Brussels sprouts is Monday high protein dinner for people who want to eat well without spending their evening in the kitchen.
Preheat the oven to 425°F. Line a baking sheet with parchment paper for easier cleanup.
Trim and halve the Brussels sprouts, slice the onion, and pat dry the pork loin. Toss vegetables with 1 tbsp olive oil and half the salt and pepper.
Rub the pork loin with remaining olive oil, garlic powder, paprika, and the rest of the salt and pepper. Allow to sit for 5 minutes for seasoning absorption.
Spread Brussels sprouts and onion on the baking sheet creating a bed, then place the pork loin on top. Roast for 22–25 minutes, turning pork halfway, until it reaches an internal temperature of 145°F.
Remove from oven, let pork rest for 5–8 minutes before slicing. Serve pork slices alongside roasted Brussels sprouts and onions for best texture.
