Ingredients

This is meant to be a brief overview of the petite beef sirloin roast recipe. For step-by-step instructions and a full printable recipe card with ingredients, please scroll down to the teal box below.

  • Top Sirloin Petite Roast: This boneless roast is cut from the top sirloin. If you don’t see it in your grocery store, ask the butcher to cut it for you.
  • Parsley: Fresh parsley adds flavor and color. You could also use rosemary or thyme instead.
  • Garlic: Fresh garlic cloves, finely minced.
  • Olive Oil: Any mild oil works in this recipe.
  • Salt and Pepper: I like to use freshly cracked black pepper and sea salt, which help enhance the rest of the ingredients.

Optional: Worcestershire sauce adds an umami flavor that is perfect with beef.

Frequently Asked Questions

Here are some questions (and answers!) readers often ask about this top sirloin roast recipe.

How long does it take to cook a sirloin roast at 325F?

Plan on cooking your roast for about 25-30 minutes per pound for medium (145°F).
Remember, all ovens cook differently, so use this as a guide. I highly recommend using a meat thermometer to cook at your desired temperature.

What temperature do you cook roast beef to for medium?

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.”

Does resting beef make it tender?

The juices will redistribute throughout the roast during this time and helps keep it juicy and tender.

Should you cover beef when resting?

Cover the beef loosely with aluminum foil, which is sometimes referred to as making a tent.

Serving Suggestions

For Sunday supper, I love to serve this roast with White Cheddar Mashed Potatoes or Make Ahead Sweet Potatoes with Brown Sugar and some sort of green vegetable like Garlic Green Beans or Roasted Parmesan Broccoli.

More Side Dish Ideas

Here are some other side dish recipe ideas you’ll love:

Storage

To Store: Store leftovers in an airtight container in the fridge for 3-5 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. You can also reheat it in a skillet on low with a little bit of beef broth.

Notes

Marinating 
For an extra flavorful roast, marinate it overnight with our Cowboy Butter.
  1. Slather 3 tablespoons of room temperature compound butter all over the roast.
  2. Place meat into a baking dish.
  3. Cover with plastic wrap and refrigerate overnight.
  4. Add a couple of dashes of Worcestershire sauce over the top of the beef just before adding the parsley and garlic mixture.
  5. Roast as per instructions.
Tips
For best results, take the beef roast out of the refrigerator 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 ensure 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.

    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.
