So, it’s that time of year again—when the house is filled with the smell of pine, the kids are basically bouncing off the walls in excitement, and Nathaniel is trying his best to hang the Christmas lights without causing any major disasters (I’m looking at you, broken ladder incident from last year). But let’s be real: the real star of Christmas is always the food. And for me, there’s no better way to do Christmas dinner than with a perfectly cooked prime rib and all the delicious sides to go with it.
Now, I’ll admit—my cooking style is equal parts “I-don’t-have-time-for-this” and “I-need-this-to-look-like-I-know-what-I’m-doing.” But with prime rib? You can’t really mess it up. It’s that wow dish that makes you feel like a total holiday hero, even if you’re secretly crossing your fingers that you don’t end up with a tough hunk of meat that no one wants to touch. Lucky for me, with a few tricks up my sleeve (thanks to years of cooking Christmas dinners and a lot of trial and error), I’ve figured out how to make it foolproof. Here’s how to get that prime rib on the table, along with some amazing sides to complete the feast.

The Perfect Prime Rib
First things first: let’s talk prime rib. If you’ve never cooked one before, let me just tell you—it’s like the Beyoncé of holiday dinners. It’s got that perfect golden brown crust on the outside, the juicy tenderness on the inside, and it’s guaranteed to make your guests’ mouths water. It’s also surprisingly easy if you know a couple of key things.
- Season it like you mean it. You want to give that beef some flavor! I love a simple rub of olive oil, garlic, salt, pepper, and fresh rosemary. Massage it in and let it sit for at least an hour before cooking. Trust me, the more you let it rest, the more the flavors have a chance to seep in.
- Low and slow is the way to go. The trick to a tender, juicy prime rib is cooking it at a low temperature. I go for about 250°F and cook it for about 3 hours for a 5-pound roast. That’s right—3 hours. But listen, you don’t want to mess with this. Get a meat thermometer, and make sure the internal temperature hits 130°F for medium-rare (or 135°F if you want it closer to medium). You’ll be amazed at how perfectly it turns out.
- Rest, baby, rest. After you pull the prime rib from the oven, let it rest for 20 minutes. I know, it’s hard to wait, but trust me—the juices need time to redistribute so you don’t end up with a sad, dry roast.
Now, if you’re feeling fancy, you can give it a quick blast of high heat at the end to get that perfect crust (about 500°F for 10 minutes), but I usually skip this step because I’m just trying to make it to the holiday cookie baking before the kids completely lose their minds.
The Sides That Steal the Show
Okay, so now you’ve got your prime rib in the oven, and you’ve got 3 hours to go—what’s next? Side dishes, my friend. A great prime rib isn’t complete without the right sides, and I’ve got a few favorites that will have your family and guests singing your praises.
Garlic Mashed Potatoes
Let’s be real, mashed potatoes are like the comfort food of the holiday world. Fluffy, creamy, and perfect with a little prime rib juice. I love adding roasted garlic to mine for that extra zing. Here’s how I make it:
- Boil a bunch of potatoes (I like Russets) until they’re fork-tender.
- Mash them up with butter, heavy cream, and a generous amount of roasted garlic.
- Season with salt and pepper to taste, and throw in a little chives or parsley for color.
These babies are always the first to disappear, and I swear, if you’re feeding your kids mashed potatoes, they’ll be distracted long enough for you to sneak in a glass of wine.
Roasted Brussels Sprouts with Balsamic Glaze
I used to think Brussels sprouts were the enemy (thank you, overcooked ones from my childhood), but when you roast them with olive oil, salt, and pepper, they get crispy and caramelized. Throw on a little balsamic glaze, and they’re a total game changer.
- Cut your Brussels sprouts in half and roast them at 400°F for about 25-30 minutes, shaking them halfway through.
- Drizzle with balsamic glaze right before serving, and boom—people will be asking for your Brussels sprouts recipe like they’re the star of the show.
Buttery Dinner Rolls
Listen, if there’s one thing I love almost as much as the prime rib, it’s soft, fluffy dinner rolls. And yes, I use store-bought for these—don’t judge. I warm them in the oven and add a little extra butter on top before serving. It’s an easy win, and no one has to know how simple they were to make.
Creamed Spinach
Okay, now this one’s for the grown-ups, but I promise—it’s worth it. Creamed spinach is rich, flavorful, and the perfect balance to the meatiness of the prime rib. Plus, I always get bonus points for sneaking some greens in on Christmas.
- Sauté spinach with butter and garlic, then add heavy cream and Parmesan cheese.
- Simmer until creamy and thickened, and then season with salt and pepper to taste.
The Big Finish: Desserts!
Alright, now that you’ve got your prime rib and sides sorted, you’ll probably need a little something sweet to wrap up the meal. I wish I had a killer dessert recipe, but let’s face it—once I’m done with the prime rib, I’m about 3 steps away from needing a nap. That said, I usually just do a simple fruit tart or something I can buy (because, hello, holiday exhaustion).
So there you have it, folks. A Christmas dinner that’ll make your family (and yourself) feel like royalty without losing your mind in the process. Now, if I could just figure out how to make it all happen without the kids constantly asking when Santa’s coming… well, then I’d have truly mastered the holiday season. But hey, it’s a work in progress.
Happy cooking, and may your Christmas be filled with delicious food, sweet memories, and maybe even a little magic (and wine).
