💭 Frequently Asked Questions
Here are some questions (and answers!) readers often ask about this top sirloin roast recipe.
Plan on cooking your roast about 25-30 minutes per pound for medium (145°F).
Remember, all ovens cook a bit differently, so use this as a guide. I highly recomend using a meat thermometer to cooking to your desired temperature.
According to the USDA, it is important to cook beef to a minimum temperature of 145°F. Allow the beef to rest for at least 5 minutes. This is considered "medium."
The juices will redistribute throughout the roast during this time and helps keep it juicy and tender.
Cover the beef loosely with a piece of aluminum foil. This is sometimes referred to as making a tent.
⭐ Tips
✔️ For best results, take the beef roast out of the refridgerator about 10 minutes before cooking.
✔️ Take care not to overcook your roast as it will become dry and chewy. I like to use a Bluetooth Thermometer with Probe because it helps to make sure that the steak is done perfectly every time. Be sure to place the thermometer into the center of the meat for an accurate read.
✔️ Don't skip resting the meat.

🍲 Storage
To Store: Store leftovers in an airtight container in the fridge for ⅗ days. (These are my favorite airtight containers.)
To Reheat: Wrap individual portions of beef in aluminum foil and place into a 350F oven for 3-5 minutes until heated throughout.
While it can be microwaved, this sometimes dries out the roast.

This was really simple to make and was quite flavorful. I used fresh parsley from my garden and extra garlic. It was so good! We made sandwiches with the leftovers today and will put the remainder of the leftovers on a salad for tomorrow's dinner.
