Ingredients & Substitutions
Here I explain the best ingredients for sirloin pork roast, what each one does in the recipe, and substitution options. For measurements, see the recipe card.
Boneless Pork Sirloin Roast – This cut is lean, flavorful, and comes from the hindquarters of the pig. Although grocery stores may have it, one from the butcher will be more fresh. This recipe would also work with other cuts of pork, but the time will vary. Olive Oil – Locks in moisture, promotes browning, and helps the seasonings stick. You could also use avocado oil. Spices – A combination of smoked paprika, sea salt, and black pepper. Butter – I prefer to use unsalted butter and salt the meat separately to control the amount. Let it sit on the counter for about 30 minutes to soften to room temperature. Garlic – Freshly minced garlic will provide the most flavor, but you can always use 2 teaspoons of jarred minced garlic for convenience. Fresh Herbs – I use fresh thyme and fresh rosemary, but you could use other fresh herbs such as oregano, sage, or even parsley to customize the pork sirloin roast to your liking. See my compound butter recipe for more ideas. Chicken Broth – I usually buy a reduced sodium variety, but regular broth works (it goes in the bottom of the pan, so doesn’t impact how salty the dish is too much), or make your own chicken broth or nutritious bone broth instead.

How Long To Cook Pork Sirloin Roast?
The cooking time for pork sirloin roast will depend on its thickness and weight, and whether or not you sear it first. A good method is to sear the roast on all sides first, then cover and roast in the oven for about 20 minutes per pound, with the last 10 minutes uncovered. The internal temperature should reach at least 140 degrees F, and will reach 145 degrees F when it rests afterward. I wasn’t able to find a whole 4-pound roast like I wanted, so mine was cut into two 2-pound roasts. Since each was 2 pounds, it took a total of 40 minutes in the oven (covered for 30, uncovered for 10).
Storage Instructions
Store: Keep leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat: I recommend reheating in the oven at a low temperature, around 250-300 degrees F. Wrap the roast in two layers of foil and place it directly on the oven grates for about 10-15 minutes to ensure it warms evenly. Avoid using a baking dish to prevent overheating. Freeze: Cool completely, then store in a zip lock bag in the freezer for up to 3 months.
What To Serve With Pork Sirloin Roast
Simple pork sirloin roast recipes like this one can go it with just about any side dish. Here are some easy ideas:
Tie it tightly. This ensures that the meat doesn’t spread, and the juices stay locked inside. Roast covered followed by uncovered. Covering for most of the time creates steam and makes the roast juicy, while uncovering at the end ensures a nice crust. Use a thermometer. This is the best way to ensure a juicy pork sirloin roast. I highly recommend a probe thermometer, because it will beep at just the right time, but a regular meat thermometer will also work. You’ll want the roast to reach 130-135 degrees F before uncovering it, then ensure it reaches 140 degrees F before removing from the oven. The internal temperature will rise another 5-10 degrees while resting. Let it rest before slicing. This allows the juices to redistribute throughout the meat for optimal tenderness. Plus, it rises to its final temperature during this time. Carve against the grain. For the most tender slices, slice the roast against the grain to break up muscle fibers.
Roasted Veggies – Roasted broccoli makes a quick and easy side, or pair this roast with fancier veggies like garlic roasted green beans or roasted brussels sprouts. Comforting Sides – Pair your roast with roasted sweet potatoes, savory mashed potatoes, or sweet honey roasted carrots for a satisfying combination. Fresh Salads – Create a balanced plate by serving your pork with a crisp garden salad, or a refreshing cucumber tomato salad. For a festive meal, make a Christmas salad instead.
