9 Easy Prime-Rib Recipes You Can Nail at Home


1. Melted Onions

  • Time Commitment: 1 hour, 5 minutes
  • Why We Love It: <10 ingredients, beginner-friendly, vegetarian

Onions as a starring side dish? We never thought it could happen, that is, until we saw (and fell in love with) these beauties. They’re made with four ingredients and a muffin tin, natch.

2. Balsamic-Brown Sugar Carrots

  • Time Commitment: 15 minutes
  • Why We Love It: ready in <15 minutes, vegetarian, <10 ingredients, beginner-friendly

Gone are the days of dumping a bag of baby carrots into a dish and ending up with a mushy, cloying, glazed side. These carrots are crisp yet tender, with plenty of tang from the vinegar.

3. Smashed Brussels Sprouts

  • Time Commitment: 40 minutes
  • Why We Love It: sheet pan recipe, <10 ingredients, vegetarian

We’re calling it now: These Brussels sprouts are the new smashed potatoes. And why not? They’re just as crispy and make an excellent vehicle for salty Parmesan cheese.

4. Hasselback Honey-Glazed Squash with Pistachios and Chiles

  • Time Commitment: 1 hour, 30 minutes
  • Why We Love It: special occasion–worthy, crowd-pleaser, <10 ingredients

Instead of falling back on the standard cubed-and-roasted treatment, give your winter squash as much love as the main course. This impressive-yet-foolproof casserole is sweet, spicy and anything but boring.

5. Dorie Greenspan’s Potato-Parm Tart

  • Time Commitment: 1 hour, 20 minutes
  • Why We Love It: crowd-pleaser, special occasion–worthy

Satiny layers of cream cheese and Parmesan between impossibly thin slices of potato, all finished with an allium of your choice. What’s left to say, other than that you’re in for a treat?

6. Green Cabbage Gratin

  • Time Commitment: 1 hour, 10 minutes
  • Why We Love It: special occasion–worthy, one pan

In our humble opinion, cabbage doesn’t get the love it deserves. But this cheesy gratin will help you see how beautifully it caramelizes and carries flavor. (OK, the breadcrumbs don’t hurt.)

7. Crispy and Spicy Harissa Potatoes with Yogurt

  • Time Commitment: 1 hour, 10 minutes
  • Why We Love It: special occasion–worthy, under 500 calories, crowd-pleaser

Do you need another potato side dish in your life? Yes, you do, and it’s this sweet-and-savory number. The pistachio and parsley toppings are relatively uncomplicated, but when they mingle with the yogurt, magic happens.

8. White Wine Braised Leeks

  • Time Commitment: 50 minutes
  • Why We Love It: <10 ingredients, special occasion–worthy

Like onions (see no. 1 on this list), we bet you’ve never really given leeks much thought. But when given a little TLC (ahem, wine and butter), they shine on their own. This tender, melt-in-your-mouth side dish will totally bowl over your dinner guests.

9. Celery Salad with Walnuts and Pecorino

  • Why We Love It: under 500 calories, beginner-friendly, crowd-pleaser

The umami, sweet and salty flavors of this sheet pan side dish go with almost any meal, prime rib included. Pomegranates add a festive flare for a holiday, but you can leave them out if you’re making this dish when they aren’t in season.

11. Smoked Gouda and Scallion Mashed Potatoes

  • Time Commitment: 45 minutes
  • Why We Love It: special occasion–worthy, beginner-friendly, crowd-pleaser

When it comes to mashed potatoes, we say more is more. A hint of smoky cheese and savory onions take these spuds from fine to fantastic.

No one will be mad if a bit of the horseradish cream sauce gets on their prime rib, promise. (In fact, you should probably serve extra on the side.)

15. Jammy Upside-Down Onion Tart

  • Time Commitment: 50 minutes
  • Why We Love It: crowd-pleaser, special occasion–worthy

Yes, this tart is stunning to look at, but it’s also deeply savory and deceptively simple to make. The toughest part is inverting it onto a serving platter.

  • Time Commitment: 1 hour, 5 minutes
  • Why We Love It: special occasion–worthy, <10 ingredients

21. Charred Cauliflower with Crunchy Garlic Chile Oil

  • Time Commitment: 25 minutes
  • Why We Love It: <30 minutes, special occasion–worthy

The more caramelized the veggie, the better, if you ask us. Plus, if your grill is already lit, this one will be a cinch to make. You might want to make a double batch of the chile oil to keep in the fridge. Just saying.

22. Kale and Brussels Sprout Caesar Slaw

  • Time Commitment: 25 minutes
  • Why We Love It: <30 minutes, crowd-pleaser, <10 ingredients

23. Pan-Roasted Broccoli ‘Steaks’ with Garlic-Sesame Vinaigrette

  • Time Commitment: 30 minutes

Roasted broccoli gets all caramelized and sweet in a way we can’t resist. This version is cooked on the stove, so you don’t even have to turn on your oven.

24. Baby Vegetables with Orange and Thyme

  • Time Commitment: 50 minutes
  • Why We Love It: sheet pan recipe, beginner-friendly, <10 ingredients

The simple combo of black pepper and cheese instantly elevates not only pasta but also pretty much every veggie, including the often maligned Brussels sprout.

26. Cauliflower with Roasted Tomatoes, Parsley and Breadcrumbs

  • Time Commitment: 55 minutes
  • Why We Love It: beginner-friendly, special occasion–worthy, <500 calories

Roasting the tomatoes brings out their natural sweetness and concentrates their jammy flavor, which is great if you’re working with off-season produce. (The cauliflower speaks for itself.)

27. Kale Salad with Crispy Chickpeas

  • Time Commitment: 1 hour
  • Why We Love It: crowd-pleaser, under 500 calories, special occasion–worthy
