Oh, Christmas dinner—the star of the holiday season! But let’s be honest, while everyone fusses over the turkey or ham, it’s the Christmas dinner side dishes that steal the show. I still remember my grandma’s mashed potatoes—creamy, buttery, and just salty enough to make you go back for thirds (or fourths, no judgment). And those green beans? Crisp-tender with a drizzle of olive oil, they were the perfect fresh contrast to all the rich flavors. Cranberry sauce? Don’t even get me started—it’s the tangy-sweet bite that ties everything together.
These sides aren’t just fillers; they’re the heart of the meal, the dishes that make your plate feel like a holiday celebration. Whether you’re feeding a crowd or keeping it cozy, these recipes are my go-tos—simple, comforting, and packed with flavor. Trust me, once you try them, they’ll become your family’s new tradition too.

Why You’ll Love These Christmas Dinner Side Dishes
Let me tell you—these sides are absolute game-changers for your holiday table. Here’s why:
- Effortless elegance: They look fancy but come together in minutes (perfect for when you’re juggling gifts and guests).
- Flavor bombs: Buttery mashed potatoes, bright green beans, and that tangy cranberry sauce? Yes, please.
- Vegetarian-friendly: No one feels left out—these dishes please everyone at the table.
- Holiday magic: They’re the comforting, familiar bites that make Christmas dinner feel like home.
Seriously, once you taste them, you’ll wonder how you ever celebrated without these sides stealing the spotlight.
Ingredients for Christmas Dinner Side Dishes
Gathering the right ingredients is half the battle for perfect holiday sides—here’s exactly what you’ll need (and yes, I’ve learned the hard way that specifics matter!):
- 2 cups mashed potatoes (warm—leftovers work great, but if making fresh, use Yukon Golds for extra creaminess)
- 1 cup green beans (trimmed and halved—trust me, bite-sized pieces mean no awkward table struggles)
- 1/2 cup cranberry sauce (homemade if you’re feeling fancy, but store-bought is totally fine—my secret? Add a splash of orange juice to jazz it up)
- 1/4 cup butter (real, salted butter—none of that margarine business, please)
- 1 tsp salt (plus more to taste—I always do a pinch in the green beans too)
- 1/2 tsp black pepper (freshly cracked if you’ve got it)
- 1 tbsp olive oil (the good stuff—this is for tossing those gorgeous green beans)
That’s it! Simple, seasonal, and oh-so-satisfying. Now let’s make some holiday magic.
Equipment You’ll Need
Don’t worry—no fancy gadgets required here! Just grab these basics (you probably already have them in your kitchen):
- A mixing bowl (for those dreamy mashed potatoes)
- A saucepan (to gently warm the cranberry sauce without burning it)
- A steamer basket (or just a pot with a lid for the green beans—improvisation is key!)
- A baking dish (if you’re reheating everything to keep it toasty for serving)
See? Told you it was simple. Now let’s get cooking!
How to Make Christmas Dinner Side Dishes
Okay, let’s get these holiday sides on the table! Follow these steps—I’ve made this enough times to know where the little pitfalls are (like over-steamed beans or lumpy potatoes). You’ve got this!
Preparing the Mashed Potatoes
First, let’s tackle those mashed potatoes. If you’re using leftovers (no shame—I do it all the time!), warm them gently in the microwave first. Then, in a mixing bowl, fold in the butter until it melts into creamy perfection. Add salt and pepper gradually—taste as you go! The key here is fluffiness: overmix, and they’ll turn gluey; undermix, and you’ll get lumps. A few gentle folds with a wooden spoon usually does the trick.
Cooking the Green Beans
While the oven preheats to 350°F, let’s steam those green beans. Toss them in a steamer basket over boiling water for exactly 5 minutes—any longer, and they lose that perfect snap. Drain them immediately, then drizzle with olive oil and a pinch of salt. Give them a quick toss—they should glisten like holiday lights!
Warming the Cranberry Sauce
Last but not least: cranberry sauce. Pour it into a small saucepan and warm it over low heat, stirring occasionally. This isn’t a race—if it gets too hot, it’ll thicken into jam (been there, ruined that). Just let it heat through until it’s pourable but still holds its shape, about 3-4 minutes.
Now, arrange everything on a platter, and watch your guests’ eyes light up. Holiday magic, served!
Tips for Perfect Christmas Dinner Side Dishes
Here’s the thing—great sides come down to little details that make a big difference. My top tricks? Taste as you go! Potatoes need more salt? Add it. Green beans too bland? A squeeze of lemon wakes them right up. And always, always garnish with fresh herbs—parsley or thyme makes everything look (and taste) festive.
Want to save stress? Make these ahead! Mashed potatoes reheat beautifully with a splash of milk, and green beans stay crisp if you shock them in ice water after steaming. Just warm everything gently before serving—your future self will thank you when you’re sipping eggnog instead of scrambling at the stove!
Variations for Christmas Dinner Side Dishes
Listen, I’m all about tradition—but sometimes you gotta mix things up! Here are my favorite easy swaps to keep your holiday table exciting:
- Swap green beans for Brussels sprouts—toss them with olive oil, roast at 400°F until crispy, and thank me later.
- Garlic mashed potatoes? Yes please! Sauté 2 cloves minced garlic in the butter first—it’s a game-changer.
- Cranberry sauce too sweet? Stir in a teaspoon of Dijon mustard for tang (sounds weird, tastes amazing).
The best part? These twists still feel festive, so nobody will suspect you strayed from Grandma’s classics!
Serving Suggestions
Oh, presentation matters—these sides deserve a holiday-worthy stage! I love arranging them in little individual ramekins for a cozy family-style feel, or going all out with a festive platter (think: mashed potatoes piled high, green beans fanned out, and cranberry sauce in a pretty bowl with a spoon). They pair perfectly with roast turkey (obviously), glazed ham, or even a vegetarian nut roast—just don’t forget the gravy boat on the side!
Storage and Reheating
Leftovers? No problem! These sides keep beautifully in the fridge for up to 3 days—just store them in airtight containers (I always sneak a little extra butter on top of the mashed potatoes before sealing them). When you’re ready to revive them, the oven’s your best friend: 350°F for 15-20 minutes brings back that fresh-made magic. In a hurry? The microwave works too—just cover the green beans with a damp paper towel to keep them from drying out. Holiday flavors, round two!
Nutritional Information
Now, let’s be real—when it comes to Christmas dinner, we’re not exactly counting calories! But if you’re curious (or need to accommodate dietary needs), here’s the scoop: these sides pack plenty of holiday flavor without going overboard. The mashed potatoes bring comfort, the green beans add freshness, and that cranberry sauce? Pure festive joy.
Remember: Nutritional values are estimates and can vary based on the specific ingredients you use (like whether you go heavy on the butter—no judgment here!). The important thing is enjoying these delicious sides with the people you love.
Frequently Asked Questions
I get asked about these Christmas dinner side dishes all the time—so here are the answers to the questions that pop up most often in my kitchen (and probably yours too!):
Can I freeze these sides? Absolutely! The mashed potatoes freeze beautifully—just stir in a little extra butter before freezing to keep them creamy. Green beans? Blanch them first, then freeze in a single layer. Cranberry sauce freezes like a dream—thaw it overnight in the fridge when you’re ready to use it.
How do I keep mashed potatoes from drying out? My secret? A splash of warm milk and another pat of butter when reheating. Cover them with foil in the oven to trap steam—they’ll stay fluffy and perfect.
Can I make these ahead? Oh honey, yes! These sides are made for prepping ahead. Do everything but the final warming the day before—your Christmas Day self will do a happy dance when all you have to do is reheat and serve.
What if I don’t have fresh green beans? Frozen works in a pinch! Just skip the steaming and roast them instead—425°F for 15 minutes with olive oil and garlic makes them crispy and delicious.
