What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most are pantry staples, and a few fresh herbs make all the difference.

• Prime Rib Roast: About 4 to 5 pounds (1.8 to 2.3 kg), bone-in is preferred for flavor and presentation.
• Garlic: 6 large cloves, minced (fresh garlic is key for that punch).
• Fresh Rosemary: 3 tablespoons, finely chopped (if you can, grab it fresh from a farmers’ market or garden).
• Olive Oil: 2 tablespoons, extra virgin (adds richness and helps the herbs stick).
• Salt: 2 teaspoons kosher salt (Diamond Crystal is my go-to for even seasoning).
• Black Pepper: 1 teaspoon freshly cracked (don’t settle for pre-ground—fresh is worth it).
• Beef Broth: 2 cups (480 ml), low sodium preferred for making the au jus.
• Red Wine: ½ cup (120 ml), dry (optional but recommended for depth in the au jus).
• Butter: 2 tablespoons unsalted, for finishing the au jus.
• Onion: 1 small, quartered (for the au jus flavor base).

Substitution Tips: If you don’t have fresh rosemary, 1 teaspoon dried will work, but fresh is best. For a gluten-free au jus, double-check your broth ingredients. No red wine? Skip it or use extra broth with a splash of balsamic vinegar for acidity.

Equipment Needed

• Roasting Pan: A sturdy pan with a rack is ideal to allow even heat circulation around the prime rib. If you don’t have a rack, crumpled foil can work as a makeshift base.
• Meat Thermometer: Essential for nail-perfect doneness (I prefer an instant-read digital one for quick checks).
• Sharp Knife: For trimming and carving—don’t use a dull blade; it will tear the meat.
• Mixing Bowl: For combining garlic, rosemary, and oil into a paste.
• Saucepan: To prepare the au jus separately while the roast rests.

If you’re on a budget, a simple oven-safe baking dish and a wire rack from your kitchen drawer can substitute for the roasting pan setup. Just keep an eye to avoid drippings burning on the bottom. Also, keep your thermometer batteries fresh—it saved me from an overcooked disaster once!

Preparation Method

1. Prep the Roast: Remove the prime rib from the fridge about 1 hour before cooking to let it come to room temperature (this helps cook evenly). Pat dry with paper towels to ensure a nice crust.
2. Make the Garlic Rosemary Paste: In a small bowl, combine minced garlic, chopped rosemary, olive oil, salt, and pepper. Mix well until it forms a paste.
3. Apply the Rub: Rub the paste all over the prime rib, covering every surface. Don’t rush this step—it’s where the flavor really sinks in.
4. Preheat the Oven: Set to 450°F (230°C). The high heat at the start helps form a flavorful crust.
5. Roast at High Heat: Place the prime rib on the rack in your roasting pan. Roast for 15 minutes at 450°F (230°C).
6. Lower the Temperature: Reduce the oven temp to 325°F (160°C) and continue roasting. Use a meat thermometer to check internal temperature: 120°F (49°C) for rare, 130°F (54°C) for medium-rare, 140°F (60°C) for medium. This usually takes about 1 ½ to 2 hours depending on size.
7. Rest the Meat: Once the target temperature is reached, remove the roast, tent loosely with foil, and let rest for 20-30 minutes (this helps juices redistribute, making the meat juicy).
8. Make the Au Jus: While the roast rests, pour off excess fat from the pan, leaving browned bits behind. Place the roasting pan over medium heat on the stove, add quartered onion, beef broth, and red wine. Scrape the pan to loosen browned bits, simmer for 10 minutes, then strain into a saucepan. Whisk in butter until melted and silky.
9. Carve and Serve: Slice the prime rib against the grain into thick slices. Serve with warm au jus on the side for dipping.

Pro Tips: Don’t skip the resting step—it’s tempting but crucial. Also, if your oven runs hot, start checking internal temps 15 minutes earlier than expected. The smell of garlic and rosemary roasting around the house will let you know you’re on the right track!

Cooking Tips & Techniques

Cooking prime rib can seem intimidating, but a few tricks make all the difference. First, always bring your meat to room temperature—cold meat straight from the fridge cooks unevenly. I’ve learned this the hard way (once ended up with a burnt crust and cold center). Patience with resting is another key; rushing this step means juicy juices running out on the cutting board.

Using a meat thermometer is a game-changer. Honestly, guessing doneness is risky with such a large cut. Insert the probe into the thickest part, avoiding bones, and check frequently near the end. Also, a high heat blast at the beginning develops that gorgeous crust we love.

For the au jus, don’t throw away those drippings! They’re packed with flavor. I like to simmer the pan bits with broth and wine, then whisk in butter for richness. If you don’t have wine, a splash of balsamic vinegar adds nice acidity.

When carving, use a sharp slicing knife and cut against the grain for tender bites. And hey, if you make a mess or get interrupted (like I did once by a barking dog), just laugh it off—good food is about joy, not perfection!

Variations & Adaptations

• Herb Variations: Swap rosemary with thyme or oregano for a different herbal twist. I once used a mix of rosemary and lavender for a subtle floral note that surprised everyone.
• Spice it Up: Add a pinch of smoked paprika or cayenne to the garlic paste for a mild kick. Perfect if you like a little heat without overpowering the beef.
• Cooking Method: Try reverse searing—slow roast at low temp (250°F/120°C) until nearly done, then finish with a hot sear in a cast-iron skillet for crust. It’s a bit more hands-on but yields fantastic texture.
• Dietary Substitutions: Use vegetable broth instead of beef broth for a lighter au jus. For a keto-friendly spin, serve with garlic butter mushrooms instead of traditional sides.

My personal favorite is adding a touch of horseradish sauce on the side—it cuts through the richness beautifully and brings a zing that wakes up the palate.

Serving & Storage Suggestions

Serve your garlic rosemary prime rib warm with the au jus poured over or on the side for dipping. It pairs wonderfully with classic sides like roasted potatoes, creamy horseradish sauce, and a crisp green salad or steamed asparagus. For drinks, a full-bodied red wine or a malty dark beer complements the rich flavors perfectly.

Leftovers? Wrap slices tightly in foil or plastic wrap and refrigerate for up to 3 days. For longer storage, freeze in an airtight container for up to 2 months. Reheat gently in a low oven (around 250°F/120°C) covered with foil to keep moisture, or warm slices in a skillet with a splash of broth.

Flavors actually deepen after resting overnight, so if you can, prepare the roast a day ahead and reheat. Just be sure the au jus is warmed separately before serving.

Nutritional Information & Benefits

This garlic rosemary prime rib offers a hearty serving of protein and essential nutrients like iron and zinc, important for energy and immunity. The fresh rosemary provides antioxidants and adds a pleasant herbal aroma without extra calories. Using minimal oil and seasoning keeps it wholesome, while the au jus adds flavor without heavy sauces.

For those watching carbs, this recipe is naturally low-carb and gluten-free, especially if you double-check broth ingredients. Just be mindful of portion sizes if you’re monitoring saturated fat intake, as prime rib is a rich cut.

Personally, I appreciate a meal like this for its balance of indulgence and simplicity—comfort food that doesn’t feel like overkill but still feels special.

FAQs

How long should I rest the prime rib after roasting?

Rest for at least 20-30 minutes tented loosely with foil. This helps redistribute juices for a tender, juicy roast.

Can I make the au jus ahead of time?

Yes! You can prepare the au jus while the roast rests or even the day before. Just reheat gently before serving.

What if I don’t have fresh rosemary?

Dried rosemary works as a substitute, but use about one-third the amount since it’s more concentrated. Fresh is best for aroma and flavor.

How do I know when the prime rib is done?

Use a meat thermometer. Aim for 120°F (49°C) for rare, 130°F (54°C) for medium-rare, or 140°F (60°C) for medium. Remember it will rise a few degrees while resting.

Can I cook prime rib without a roasting rack?

Yes, place the roast on a bed of coarsely chopped onions or use crumpled foil to lift it slightly off the pan bottom. This prevents sticking and promotes even cooking.
