  1. Heat oven to 450F / 232C. Set out two sheet pans.

  2. While oven heats, toss brussels sprouts with first part of olive oil and some salt and pepper. Spread out on one sheet pan. Nestle pork tenderloin in the center of brussels sprouts. Tenderize pork with a fork. Combine Italian seasoning, paprika, salt and black pepper. Rub seasoning on all sides of pork.

  3. Transfer brussels sprouts and pork to oven and roast for 20 to 22 minutes or until sprouts are tender and pork reaches 145F / 63C.

  4. Meanwhile, brush second sheet pan with second part of olive oil (add more if needed to completely cover the bottom of the pan). Spread potatoes out over pan. Use a potato masher or fork to flatten / mash the potatoes. Brush the tops of the potatoes with third part of olive oil. Season potatoes generously with some salt and pepper. Transfer pan to oven and roast potatoes until golden and crisp on the top, 18 to 20 minutes. 

  5. When pork is finished, transfer to a cutting board and let rest, covered, for 5 minutes. (If you’d like the brussels sprouts more tender and / or the potatoes more golden brown, you can continue roasting them while the pork rests.)

  6. Slice pork and serve with potatoes and brussels sprouts. Serve creamy mustard sauce on the side - it’s great for dipping everything! Enjoy!
