Boneless Rib Eye Roast: Look for a well-marbled beef cut so it stays juicy and tender as it roasts.
Fresh Rosemary: Fresh herbs deliver much brighter flavor than dried — plus, they add a pretty garnish.
Garlic: The star of the show! Using a big quantity upfront ensures a delicious garlicky punch without overpowering.
Salt and Black Pepper: Keep these basics ready to generously season the meat for balanced flavor enhancement.
Olive Oil & Vegetable Oil: Olive oil helps make the herb paste smooth, while a high-heat oil is perfect for searing.
Unsalted Butter: Adds richness to the mushrooms and silky texture to the sauce.
Mushrooms: Choose a mix or your favorite variety, sliced evenly so they cook through nicely.
Beef or Chicken Stock: Use stock to deglaze and create a flavorful pan sauce that ties everything together.

Tweak to Your Taste

I love how adaptable this Rosemary Garlic Roast Beef Recipe is. Depending on what I have on hand or the season, I tweak the herbs or add extras to the sauce. Don’t be afraid to make this recipe your own!

Herb Swap: Sometimes I add thyme or oregano with rosemary for a different herbal profile—it’s equally fresh and delicious.
Garlic Intensity: Like it milder? Use fewer cloves or roast the garlic first for a sweeter, gentler taste.
Mushroom Mix: Combining shiitake, cremini, and button mushrooms adds texture and layered flavors to the pan sauce.
Make it Spicy: A pinch of chili flakes in the herb paste gives a little heat that wakes up your taste buds in a fun way.

Step-by-Step: How I Make Rosemary Garlic Roast Beef Recipe

Step 1: Prep and Season the Roast

I start by tying the boneless rib eye roast to keep its shape during cooking—this is especially helpful if your roast isn’t perfectly uniform. Then, I season it generously with salt and freshly ground black pepper. Don’t be shy here; good seasoning is key for flavor throughout the roast. Meanwhile, mix chopped fresh rosemary and garlic with olive oil to form a paste. This paste will create that signature crust we’re aiming for.

Step 2: Sear the Meat to Lock in Juices

Using a cast iron skillet (trust me, it’s worth it!), heat vegetable oil over medium heat until it’s almost smoking. Then, sear all sides of the roast—this takes about 5 to 8 minutes total. The goal here is not to cook through, but to build that beautiful caramelized crust that keeps the meat juicy inside. Once seared, remove the skillet from heat and brush the rosemary-garlic paste all over the roast. This step fills your kitchen with a mouthwatering aroma, and you’ll know it’s working its magic!

Step 3: Roast Until Perfectly Medium-Rare

Pop the cast iron skillet with the roast into your preheated 350ºF oven. Plan for about 1 to 1.5 hours—though the best method is to use an instant-read meat thermometer. Aim for an internal temperature of 135ºF for medium-rare; the roast will continue cooking while it rests. Once out of the oven, cover the roast loosely with foil and let it rest at least 10 minutes. This allows the juices to redistribute so every slice stays juicy and tender.

Step 4: Create That Irresistible Mushroom Pan Sauce

While the roast rests, I sauté the sliced mushrooms in 2 tablespoons of butter over medium heat. Cook them until all liquid evaporates and they’re tender, about 5 minutes. Season with salt and pepper. Then, place the skillet back on the stove, pour in beef stock to deglaze, and scrape those delicious brown bits off the bottom—they’re flavor gold. Let the sauce simmer until it thickens slightly, then stir in the mushrooms and the remaining 2 tablespoons of butter. The sauce should be silky and rich. Finally, nestle the roast back in the skillet, spoon some sauce over it, and you’re good to go!

Pro Tips for Making Rosemary Garlic Roast Beef Recipe

Use a Meat Thermometer: Don’t guess doneness! This helps you nail medium-rare every time without overcooking.
Let it Rest Properly: I learned this the hard way—the resting period makes all the difference in juicy slices.
Don’t Skip Searing: That crust not only adds flavor but seals in the juices so your roast isn’t dry.
Even Mushroom Slicing: Cutting mushrooms to a uniform size ensures they cook evenly and blend perfectly into the sauce.

Garnishes

I love garnishing the serving platter with a few fresh rosemary sprigs—it adds a lovely earthy aroma and looks so elegant. Sometimes, I sprinkle a little flaky sea salt over the sliced beef just before serving to add a delicate crunch and highlight the flavors.

Side Dishes

This roast pairs beautifully with classic sides like roasted potatoes tossed with garlic and herbs, creamy mashed potatoes, or even a crisp green salad to lighten things up. If you’re feeling indulgent, buttery garlic bread or a rich gratin dauphinois are fantastic accompaniments.

Creative Ways to Present

For special occasions, I’ve placed sliced roast beef on a wooden cutting board with little ramekins of the mushroom sauce around it, letting guests serve themselves. Adding roasted cherry tomatoes or grilled asparagus alongside brightens the presentation and adds color to the plate.

Make Ahead and Storage

Storing Leftovers

I usually slice any leftovers and store them tightly wrapped in an airtight container in the fridge. This way, the beef stays tender and the flavors don’t fade. It’s best to use them within 3-4 days for maximum freshness and taste.

Freezing

Freezing roast beef works great if you want to save some for later. I freeze slices separated by parchment paper inside a freezer-safe bag or container. When you thaw, do so overnight in the fridge to keep that tender texture intact.

Reheating

To reheat, I gently warm the beef slices in a covered skillet over low heat with a splash of broth or water to keep them moist. Avoid microwaving if you can—it tends to dry out the meat. For the mushroom sauce, a quick reheat on the stove works beautifully to revive its silky texture.

FAQs

Can I use different cuts of beef for this Rosemary Garlic Roast Beef Recipe?

Absolutely! While boneless rib eye roast is ideal for its marbling and tenderness, you can use sirloin, top round, or even a strip loin. Just remember cooking times will vary. Using a meat thermometer is your best bet to hit the perfect doneness.
How long should I roast the beef for medium-rare?

Generally, roast at 350ºF for about 1 to 1.5 hours depending on size. The best method is to use an instant-read thermometer and pull the roast when it hits 135ºF internal temperature. After resting, it will reach the ideal medium-rare temperature of 145ºF.
Can I prepare the herb-garlic paste ahead of time?

Yes! The rosemary-garlic paste can be made a day ahead and stored in the fridge covered tightly. This actually lets the flavors meld beautifully, so don’t hesitate to prepare it in advance to save time.
Is it okay to use dried rosemary instead of fresh?

Fresh rosemary is definitely preferred for its bright flavor, but if you only have dried, use about one-third the amount and crush it slightly to release aroma. Just be mindful that dried herbs are more concentrated and can be a bit bitter if overused.
