Sirloin Roast Beef with a 3 ingredient Dijon peppercorn crusted top makes an elegant holiday dinner. Oven roasted to your preference with these tips!
This sirloin roast beef recipe holds a special place in my heart.
It was the first family dinner I prepared in our new home.
We’ve been in our new house for nearly a month, but we’re completely settled and it has felt like home since Day 1. And nothing says “home” like a roast beef dinner, my favorite comfort meal!
Although I normally throw roasts into the slow cooker, I recently got a new internal probe thermometer, so I’ve been experimenting with cooking roasts in the oven. This peppercorn sirloin roast baked up perfectly. It has a simple 3 ingredient rub on top made of Dijon mustard, garlic and crushed peppercorns. I had a peppercorn crusted sirloin roast beef at a restaurant nearly 8 years ago. That savory peppercorn flavor hit the spot that night and I finally (took me long enough, right?) made my own version at home.
Beef is often the centerpiece for holiday dinners. A roast can make a beautiful presentation! Giving an exact time for cooking this sirloin roast is a little tricky since every roast is a different size. I like to bake sirloin roasts slowly in the oven at 325 degrees. By inserting an internal probe thermometer into the center of the roast, you can bake the beef to the exact temperature and doneness that your family prefers: Rare (125 degrees), Medium Rare (135 degrees), Medium (145 degrees), Medium Well (150 degrees) and Well Done (160 degrees).
Serve this peppercorn sirloin roast beef with a side of corn casserole, potatoes, veggies and freshly baked rolls. It will warm you up inside on these cold winter days!
