How to Make Rosemary and Garlic Roast Beef with Mushroom Sauce Recipe

Step 1: Prepare and Season the Roast

Begin by preheating your oven to 350ºF, setting the perfect temperature for roasting the beef gently yet thoroughly. Tie your rib eye roast to ensure even cooking and season it generously with salt and freshly ground black pepper. This foundational seasoning is vital for enhancing all the natural flavors of the meat.

Step 2: Make the Herb-Garlic Paste

Mix the chopped fresh rosemary and garlic in a bowl, then stir in 2 tablespoons of olive oil. This paste not only infuses the beef with its signature aroma but also helps develop a flavorful crust during roasting—don’t skip this essential step.

Step 3: Sear the Roast

Heat the vegetable oil in a cast iron skillet over medium heat until it’s smoking hot. Sear the roast on all sides for about 5 to 8 minutes until it achieves a beautiful, golden-brown crust. This step seals in the juices and adds incredible flavor.

Step 4: Coat Roast and Roast in Oven

Remove the skillet from the heat and brush the herb-garlic paste all over the roast, ensuring every surface is covered. Then, place the skillet with the roast directly into the preheated oven. Roast for approximately 1 to 1.5 hours or until a meat thermometer reads 135ºF for medium-rare. Let the roast rest for at least 10 minutes; this resting allows the juices to redistribute for the perfect tender bite.

Step 5: Prepare the Mushroom Sauce

While your roast rests, sauté the sliced mushrooms in 2 tablespoons of butter over medium heat until all moisture evaporates and the mushrooms are cooked through, approximately 5 minutes. Season them lightly with salt and pepper to enhance their natural umami.

Step 6: Deglaze and Finish the Sauce

Remove the roast from the skillet. Place the skillet back on the stovetop and pour in the beef (or chicken) stock to deglaze—scraping up those irresistible browned bits from the bottom. Simmer until the liquid thickens slightly, then stir the mushrooms back into the pan. Add the remaining 2 tablespoons of butter and stir until the sauce is silky and glossy. Place the roast back into the skillet and spoon some of the mushroom sauce over it to meld the flavors beautifully.

Garnishes

Adding a few sprigs of fresh rosemary to your serving platter not only looks stunning but reinforces the herbal note of the dish. You can also sprinkle a touch of coarse sea salt over the roast just before serving to add a subtle crunch and burst of flavor.

Side Dishes

This roast beef pairs incredibly well with classic mashed potatoes or roasted root vegetables. The creamy texture of mashed potatoes balances the succulence of the beef, while roasted carrots, parsnips, or Brussels sprouts add sweetness and a slight crisp contrast that rounds out the meal.

Creative Ways to Present

For a family-style dinner, slice the roast thickly on a wooden carving board, surrounded by heaps of the mushroom sauce. Alternatively, arrange thin slices over a bed of buttered egg noodles or creamy polenta and drizzle generously with mushroom sauce for a rustic yet elegant look that will wow your guests.

Make Ahead and Storage

Storing Leftovers

Leftover roast beef can be refrigerated in an airtight container for up to 3 days. It’s best to store the meat and mushroom sauce separately to keep textures intact for reheating.

Freezing

You can freeze leftover roast beef wrapped tightly in foil or plastic wrap, placed inside a freezer bag for up to 2 months. Freeze the mushroom sauce in a sealed container separately to maintain freshness and flavor.

Reheating

Always reheat the beef gently in the oven at low temperature (around 300ºF) to keep it tender, and warm the mushroom sauce slowly on the stovetop, stirring occasionally to preserve its silky texture.

FAQs

Can I use a different cut of beef for this recipe?

While rib eye roast is ideal for its marbling and tenderness, you can use other cuts like sirloin or top round. Just bear in mind, cooking times and results will vary slightly based on fat content and muscle structure.

How do I know when the roast is done?

The best way is to use a meat thermometer. For medium-rare, you want to remove the roast at 135ºF and let it rest; it will rise to about 145ºF while resting, ensuring perfect doneness.

Can I prepare the herb-garlic paste ahead of time?

Yes! You can make the rosemary and garlic paste up to a day in advance and keep it covered in the refrigerator. This actually helps the flavors meld wonderfully overnight.

What types of mushrooms work best for the sauce?

A combination of cremini, shiitake, and button mushrooms adds great texture and depth, but feel free to use any mushrooms you love or have on hand for a personalized touch.
