Ingredients You’ll Need

2 pounds beef sirloin: A tender cut that holds up well in the oven and creates intense flavors as it roasts.
1 pound baby potatoes: These bite-sized beauties are easy to roast and soak up the garlic and herb goodness.
4 cloves garlic, minced: Fresh garlic lends a strong, aromatic flavor that complements the meat.
2 tablespoons olive oil: Helps the spices adhere and adds richness while roasting.
1 teaspoon salt: Essential in enhancing the flavors of the beef and potatoes.
1/2 teaspoon black pepper: Provides a slight kick that balances the dish.
1 teaspoon dried thyme: A classic herb that pairs beautifully with beef and adds earthy notes.
1 teaspoon rosemary: Its pine-like fragrance and taste elevate the entire dish.

How to Make Roast Sirloin with Potato Bake

Preheat your oven: Start by preheating your oven to 400°F (200°C). This ensures that your meat and potatoes start roasting immediately, sealing in the juices and maximizing flavor.

Prepare the garlic mixture: In a medium bowl, mix together 4 cloves of minced garlic, 2 tablespoons of olive oil, 1 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon dried thyme, and 1 teaspoon rosemary. This aromatic blend is going to be the star of the show!

Rub the garlic mixture: Generously rub the prepared garlic mixture all over the 2 pounds of beef sirloin, making sure it gets into all the nooks and crannies for maximum flavor. The oil will help lock in moisture during cooking.

Arrange for roasting: Place the seasoned beef sirloin in a roasting pan and surround it with 1 pound of baby potatoes. Ensure the potatoes are evenly distributed around the beef, as they will soak up the savory flavors from the meat while cooking.

Roast the beef: Place the roasting pan in your preheated oven and let it roast for about 1 hour. A meat thermometer inserted into the thickest part of the beef should read 135°F (57°C) for medium-rare. If you prefer a different doneness, adjust the cooking time accordingly.

Let it rest: Once the beef is ready, remove it from the oven and let it rest for 10 minutes. This is an important step as it allows the juices to redistribute throughout the meat, helping to keep it tender and juicy when you slice it.

Serve: After resting, slice the sirloin against the grain and serve it alongside the roasted garlic potatoes. Enjoy every bite of your home-cooked masterpiece!

Storing & Reheating

To store any leftovers, let them cool to room temperature, then place them in an airtight container. They can be kept in the fridge for up to 3 days. For longer storage, freeze the sliced beef and potatoes separately in freezer-safe bags for up to 3 months. To reheat, simply microwave for 1-2 minutes or warm in the oven at 350°F (175°C) until heated through. You might notice a slight change in texture after freezing, but a quick pop in the oven will refresh them nicely.

Chef’s Helpful Tips

Avoid overcooking the beef. Using a meat thermometer can help ensure you reach the desired doneness without drying out the meat.
Let the beef come to room temperature before rubbing it with the garlic mixture; this helps in even cooking.
If you want extra crispy potatoes, place them cut-side down near the beef for those last few minutes in the oven.
Feel free to add other vegetables, like carrots or asparagus, to the roasting pan for a one-pan meal.
Experiment with your herbs! Fresh herbs can elevate this dish further, so consider using fresh rosemary or thyme if available.

Roasted Beef Sirloin with Garlic Potatoes is not just another meal—it’s a way to bring warmth and love to your table. I encourage you to experiment with the flavors, perhaps adding some red wine to the pan for a richer sauce or trying out different herbs that suit your palate. This dish is all about making it your own and enjoying the process. So gather your ingredients and enjoy cooking!

Recipe FAQs

Can I use a different cut of beef?

Absolutely! While sirloin is a fantastic choice, you can substitute with ribeye or tenderloin for a richer flavor, or choose a chuck roast for a more budget-friendly option. Just be mindful that cooking times may vary based on the cut.

How can I make the potatoes extra crispy?

For crispy potatoes, make sure they are well-coated in the garlic and olive oil mixture. You can also give them a quick boil for 5-10 minutes before roasting to kickstart the cooking and increase crispiness.

What should I serve with this dish?

This hearty roast is perfect on its own, but you can pair it with a fresh salad or some roasted seasonal vegetables for added nutrition. A light dressing or chimichurri sauce can also offer a refreshing contrast to the richness of the beef.

How do I know if my beef is done?

For medium-rare, you’re looking for a temperature of 135°F (57°C). If you prefer medium, aim for 145°F (63°C). Always insert the thermometer into the thickest part of the meat for an accurate reading.
