Ingredients You’ll Need

All great roasts start with a handful of thoughtfully chosen ingredients, and this recipe is no exception. Every element has a job to do — from the fragrant herbs to the robust cut of beef — blending together to create an unforgettable Rosemary and Garlic Roast Beef.

3 pounds boneless Rib Eye roast: The marbling makes this cut juicy, delicious, and perfect for roasting.
¼ cup chopped fresh rosemary: Nothing beats the aroma of fresh rosemary for injecting flavor all the way through the beef.
¼ cup chopped garlic (about 20 cloves): Garlic not only seasons but also creates a beautifully caramelized crust.
Salt and freshly ground black pepper to taste: Simple but crucial for coaxing out the natural flavors of the meat.
2 tablespoons olive oil: Helps make an herb paste that clings perfectly to the roast.
2 tablespoons vegetable oil: For high-heat searing that gives that coveted crust.
4 tablespoons unsalted butter, divided: Adds richness to the sauce and finishes the mushrooms with a glossy sheen.
4 cups a variety of mushrooms, sliced to about the same size: Mushrooms soak up all those savory pan juices and make the sauce unforgettable.
1 cup beef (or chicken) stock: A splash of stock deglazes the pan and elevates the sauce’s flavor.

How to Make Rosemary and Garlic Roast Beef

Step 1: Preheat and Prepare the Roast

Kick things off by preheating your oven to 350ºF. While it’s heating up, take a moment to tie your rib eye roast with kitchen twine. This simple trick helps the beef keep its beautiful shape while roasting, which ensures more even cooking and an impressive final look. Generously season the roast on all sides with salt and freshly ground black pepper — don’t be shy, this is the foundation of flavor!

Step 2: Make the Rosemary-Garlic Paste

Now, grab a small bowl and mix together your chopped fresh rosemary, all that gorgeous garlic, and the olive oil. Stir to form a fragrant, chunky paste. This powerhouse mixture will become the bold, aromatic layer that makes this Rosemary and Garlic Roast Beef truly unforgettable. Set it aside until you’re ready to gild your roast.

Step 3: Sear the Roast

Heat your cast iron skillet over medium heat and pour in the vegetable oil. Wait for the oil to be shimmering hot — it should just start to smoke. Place your seasoned roast into the skillet and sear on all sides for about 5–8 minutes total. Searing locks in the juices and forms a crave-worthy crust, setting the stage for a juicy, flavorful center.

Step 4: Coat with Herb-Garlic Paste

Take the skillet off the heat and grab your rosemary-garlic paste from earlier. Using a brush or your hands, slather the paste generously over the entire roast. The aroma at this point is enough to make anyone hungry — trust me! The paste will bake into a delicious, caramelized exterior.

Step 5: Oven Roast

Transfer the skillet with your paste-covered roast into the preheated oven. Roast for 1 to 1.5 hours, or until a meat thermometer registers 135°F for medium-rare. Take your time here, and let that gentle heat work its magic. Once it’s done, cover loosely with foil and let it rest for at least 10 minutes, allowing the juices to redistribute—this keeps the meat tender and moist. Final internal temp should reach 145°F for medium rare perfection!

Step 6: Sauté the Mushrooms

While your Rosemary and Garlic Roast Beef is resting, use a separate pan or the same skillet (if your roast has been moved to a platter) to sauté the mushrooms. Melt 2 tablespoons of butter over medium heat, add your sliced mushrooms, and stir occasionally for about 5 minutes. The mushrooms should become golden and tender, and any excess liquid should evaporate. Season lightly with salt and pepper.

Step 7: Make the Mushroom Sauce

Remove the roast from the skillet, and put the skillet back on the stove. Pour in your beef or chicken stock, scraping up all those flavorful browned bits on the bottom. Simmer until the liquid is reduced and slightly thickened. Add the sautéed mushrooms and the remaining 2 tablespoons of butter, stirring until the sauce is silky and luxurious. Now, nestle the roast back in if you like, spooning sauce over the top so every slice soaks up those deeply savory flavors.

How to Serve Rosemary and Garlic Roast Beef

Garnishes

Fresh rosemary sprigs look beautiful and add extra fragrance to your serving platter. A sprinkle of flaky sea salt just before serving accentuates the flavors even more. For a burst of color, toss on a sprinkle of fresh chopped parsley or chives — simple touches, but they make your Rosemary and Garlic Roast Beef pop!

Side Dishes

Classic, comforting sides are always welcome: think creamy mashed potatoes, oven-roasted root vegetables, or a crisp green salad with tangy vinaigrette. Yorkshire puddings or crusty bread are also perfect for mopping up that incredible mushroom sauce. With sides this good, your roast will taste even better.

Creative Ways to Present

Slice the roast at the table for added drama — let everyone marvel at the mouthwatering crust and juicy pink center. You can arrange the sliced Rosemary and Garlic Roast Beef fanned out on a large serving board, surrounded by heaps of mushrooms and a drizzle of sauce, for a bistro-style presentation. If you’ve got leftovers, pile slices onto crusty rolls with arugula and horseradish cream for next-level sandwiches.

Make Ahead and Storage

Storing Leftovers

Wrap leftover Rosemary and Garlic Roast Beef tightly in foil or transfer to airtight containers. Refrigerate for up to 4 days. The mushroom sauce can be stored separately in a lidded container in the fridge to keep both in the best condition.

Freezing

To freeze, slice the roast and place parchment between slices to prevent sticking. Seal in freezer bags or containers with the sauce on the side. Both can be frozen for up to 2 months. Thaw overnight in the fridge before reheating and you’ll be rewarded with nearly-fresh tenderness.

Reheating

Gently reheat sliced Rosemary and Garlic Roast Beef in a covered baking dish with a little extra stock or sauce to keep it moist. Warm in a 300ºF oven until just heated through — avoid microwaving if you can, as it can toughen the meat. Reheat the sauce separately on the stovetop, then combine to serve.

FAQs

Can I use a different cut of beef for Rosemary and Garlic Roast Beef?

Absolutely! While boneless rib eye is preferred for its marbling and tenderness, cuts like sirloin roast or top round work nicely. Just remember to adjust cooking times, as leaner cuts cook faster and can dry out if overdone.

What type of mushrooms work best?

A mix of cremini and shiitake adds lots of depth, but don’t hesitate to use whatever you have on hand. Even basic button mushrooms will soak up the sauce and turn out delicious!

Can I prepare the herb and garlic mixture in advance?

Yes, you can make the rosemary-garlic paste a day ahead and refrigerate it. Let it come to room temperature before using, to ensure it spreads evenly on the roast.

How do I make sure my roast is medium rare?

A meat thermometer is your best friend! For the ideal medium-rare Rosemary and Garlic Roast Beef, pull the roast from the oven at 135ºF and let it rest; the temperature will rise to the perfect 145ºF as it rests.

Is it possible to make this recipe dairy-free?

Definitely — simply swap the butter for a dairy-free butter alternative or omit it entirely. The sauce will still be rich from the pan juices and stock, though the buttery finish is lovely if tolerated.

Final Thoughts

This Rosemary and Garlic Roast Beef is a recipe that truly delivers: rustic, full-flavored, and unfailingly satisfying. It’s the kind of meal that makes you want to gather around the table and linger a little longer. Give it a try, and don’t be surprised if it becomes your new signature roast!
