Ingredients for Garlic Butter Prime Rib Roast

Gathering the right ingredients is key to nailing this garlic butter prime rib roast. Here’s what you’ll need:

• 1 (5-pound) prime rib roast – Look for good marbling, and don’t trim too much fat—it keeps the roast juicy!
• ½ cup unsalted butter, softened – Trust me, room-temperature butter makes blending the herbs so much easier.
• 6 cloves garlic, minced – Fresh is best here—no jarred stuff if you can help it.
• 2 tbsp fresh rosemary, chopped – Those fragrant little needles are worth the extra chopping time.
• 2 tbsp fresh thyme, chopped – The woody flavor pairs perfectly with the beef.
• 1 tbsp salt – I use coarse kosher salt for even seasoning.
• 1 tbsp black pepper – Freshly cracked gives the best flavor punch.

That’s it! Simple, quality ingredients that let the prime rib shine. Now let’s make some magic happen.

Equipment Needed

Here’s what you’ll need to make this garlic butter prime rib roast:

• Roasting pan with rack – Keeps the roast elevated for even cooking.
• Meat thermometer – The only way to guarantee perfect doneness.
• Mixing bowl – For whipping up that glorious garlic butter.
• Sharp knife – For slicing your masterpiece.

That’s it! No fancy gadgets—just the basics for roast perfection.

How to Prepare Garlic Butter Prime Rib Roast

Alright, let’s get down to business! Making this garlic butter prime rib roast is easier than you think, but there are a few key steps that’ll take it from good to “Oh my goodness, can I have seconds?” Here’s exactly how I do it every time.

Step 1: Preparing the Garlic Butter Mixture

First things first – let’s make that magical garlic butter! In a small bowl, mix together your softened butter, minced garlic, chopped rosemary and thyme, salt, and pepper. I like to use a fork to really mash it all together until it’s completely combined and fragrant. You’ll know it’s ready when the whole kitchen smells like an Italian grandmother’s dream.

Step 2: Coating the Roast

Now for the fun part – getting hands-on with that beautiful prime rib! Pat your roast dry with paper towels (this helps the butter stick better), then massage that garlic butter mixture all over, especially on the fat cap side. Don’t be shy – really work it into every nook and cranny. The fat side is extra important because as it renders, it’ll baste the whole roast in garlicky goodness.

Step 3: Roasting the Prime Rib

Here’s my secret weapon method: Start with that oven screaming hot at 450°F. This initial blast gives us that perfect crust. Pop the roast in (fat side up, always!) and let it work its magic for 15 minutes. Then – and this is crucial – reduce the heat to 325°F without opening the oven door. Now we’re in for the long haul – about 15 minutes per pound. But here’s the thing – timing can vary, so that meat thermometer is your best friend. Pull it at 120°F for rare (it’ll come up to 130°F while resting) or 130°F for medium-rare. Resist the urge to peek too often – we want to keep that heat steady!

Step 4: Resting and Serving

When it hits temp, take it out and – this is important! – let it rest for at least 15 minutes before slicing. I know it’s tempting to dig right in, but this lets all those incredible juices redistribute. When you’re ready, slice against the grain for the most tender bites, and get ready for the compliments to roll in!

Tips for the Perfect Garlic Butter Prime Rib Roast

Want to nail this garlic butter prime rib roast every single time? Here are my tried-and-true tips:

• Bring it to room temp: Let the roast sit out for 1-2 hours before cooking. This ensures even cooking from edge to center.
• Don’t skimp on the meat thermometer: Timing varies, so trust the temp, not the clock. Pull it at 120°F for rare or 130°F for medium-rare.
• Rest is best: Letting it sit for 15 minutes after roasting keeps all those delicious juices inside.
• Season generously: That butter mixture needs to coat every inch for maximum flavor.
• Keep the fat cap: Don’t trim it too much—it bastes the roast as it cooks.

Follow these, and you’ll have a showstopper every time!

Ingredient Notes and Substitutions

Don’t stress if you’re missing an ingredient for this garlic butter prime rib roast! Here’s how to adapt:

• Fresh herbs: No rosemary or thyme? Use 1 tsp dried for each tbsp fresh (crush between fingers to release oils).
• Butter: Salted butter works too—just reduce added salt by half. Margarine? Don’t tell my grandma I suggested it.
• Garlic: In a pinch, ½ tsp garlic powder per clove works, but fresh really makes the magic happen.
• Prime rib: Can’t find it? A ribeye roast or standing rib roast are practically the same cut.

The beauty of this recipe? It’s flexible without sacrificing that wow factor!

Serving Suggestions for Garlic Butter Prime Rib Roast

This garlic butter prime rib roast deserves equally amazing sides! My go-tos are creamy mashed potatoes (perfect for soaking up those juices), roasted Brussels sprouts with bacon, or a crisp arugula salad with shaved parmesan. For holidays, I’ll add Yorkshire puddings—they’re basically edible gravy boats!

Storage and Reheating Instructions

Leftovers? (If you’re lucky enough to have any!) Store your garlic butter prime rib roast in an airtight container in the fridge for up to 3 days. When reheating, go low and slow—slice what you need and warm it gently in a 300°F oven for about 10 minutes. This keeps it juicy instead of turning it into shoe leather. Pro tip: The cold slices make incredible sandwiches—just pile them on crusty bread with a little horseradish sauce!

Frequently Asked Questions About Garlic Butter Prime Rib Roast

I get so many questions about this garlic butter prime rib roast recipe! Here are the ones that pop up most often:

Can I use dried herbs instead of fresh?
Absolutely! Just remember dried herbs are more concentrated – use 1 teaspoon dried for every tablespoon fresh the recipe calls for. Crush them between your fingers first to wake up those oils!

How do I know when the roast is done?
The meat thermometer is your best friend here. Pull it at 120°F for rare (it’ll rise to 130°F while resting) or 130°F for medium-rare. Never trust cooking time alone – every oven and roast behaves differently!

Can I make this ahead of time?
You can prep the garlic butter mixture a day in advance (keep it covered in the fridge), but apply it right before roasting. The roast itself is best served fresh from the oven for that perfect crust.

What if I don’t have a roasting rack?
No worries! Create a makeshift rack by laying thick slices of onion or carrots in the pan – they’ll elevate the roast while adding extra flavor to your drippings.

How many people does this serve?
A 5-pound roast typically serves about 8 people generously. If you’ve got big eaters or want leftovers (hello, amazing sandwiches!), consider going bigger.
