13 Easy Low Carb Christmas Side Dishes To Impress Everyone
This isn’t just a random list of recipes. It’s a curated collection of the absolute best, no-fail low-carb side dishes to complete your holiday menu. We’ve covered everything from decadent, cheesy comfort food and classic remakes to fresh, vibrant roasted vegetables. This is your authoritative guide to building the perfect, crowd-pleasing, and healthy Christmas dinner spread for 2025.
1. The Ultimate Creamy Cauliflower Mash
Pin this creamy potato substitute for your holiday feast!
This isn’t just a substitute for mashed potatoes; it’s an upgrade. By using fresh cauliflower and full-fat cream cheese, this keto cauliflower mash achieves a silky-smooth texture that’s never watery. It’s the perfect canvas for rich gravy and a must-have for any low-carb holiday meal.
Ingredients Needed:
- 1 large head of fresh cauliflower, cut into florets
- 4 oz full-fat block cream cheese, softened
- 4 tbsp unsalted butter
- 2 cloves garlic, minced
- Salt and black pepper to taste
- 1 tbsp fresh chives, chopped (for garnish)
Step-by-Step Directions:
- Place cauliflower florets in a steamer basket over boiling water. Cover and steam for 10-12 minutes, or until fork-tender. Do not boil, as this makes it watery.
- Drain the cauliflower very well. Pat it dry with paper towels or use a salad spinner to remove all excess moisture. This step is critical.
- Transfer the dry cauliflower to a large bowl. Add the softened cream cheese, butter, and minced garlic.
- Use a powerful immersion blender to blend the mixture directly in the bowl until it’s completely smooth and creamy.
- Season generously with salt and pepper. Garnish with fresh chives before serving.
The secret to non-watery mash is twofold: steam, don’t boil the cauliflower, and then dry it thoroughly before blending. Squeezing it in a cheesecloth is an extra step that guarantees perfect texture.
2. Classic Low-Carb Green Bean Casserole
Save this keto twist on a holiday classic!
Forget the canned soup and high-carb fried onions. This low-carb green bean casserole features fresh green beans in a rich, homemade cream sauce with sautéed mushrooms. The genius topping of crushed pork rinds and Parmesan cheese delivers that essential crunch everyone loves.
Ingredients Needed:
- 1 lb fresh green beans, trimmed
- 8 oz cremini mushrooms, sliced
- 1 tbsp butter
- 4 oz cream cheese, softened
- 1/2 cup heavy cream
- 1/4 cup grated Parmesan cheese
- 1/2 cup crushed pork rinds (for the crunchy topping)
- Salt and pepper to taste
Step-by-Step Directions:
- Preheat your oven to 375°F (190°C).
- Blanch the green beans in boiling salted water for 3-4 minutes, then immediately transfer to an ice bath to stop the cooking. Drain well.
- In a large skillet, melt the butter over medium heat. Sauté the sliced mushrooms until browned, about 5-7 minutes.
- Reduce heat to low and stir in the cream cheese and heavy cream until a smooth sauce forms. Season with salt and pepper.
- Fold the blanched green beans into the cream sauce. Transfer the mixture to a casserole dish.
- In a small bowl, combine the crushed pork rinds and Parmesan cheese. Sprinkle evenly over the top of the casserole.
- Bake for 20-25 minutes, or until bubbly and the topping is golden brown.
For an extra savory flavor, add a tablespoon of bacon grease when you sauté the mushrooms. This adds a depth that perfectly complements the creamy sauce.
3. Crispy Bacon-Roasted Brussels Sprouts
Pin this simple and delicious vegetable side dish idea!
This is the recipe that converts Brussels sprouts haters into lifelong fans. Roasting at high heat with thick-cut bacon transforms them into crispy, savory, and slightly sweet bites of perfection. This is one of the easiest and most popular Christmas vegetable side dishes you can make.
Ingredients Needed:
- 1.5 lbs Brussels sprouts, trimmed and halved
- 6 slices of thick-cut bacon, chopped
- 2 tbsp olive oil
- Salt and freshly ground black pepper
- Optional: 1 tbsp sugar-free balsamic glaze
Step-by-Step Directions:
- Preheat your oven to 400°F (200°C). This high heat is essential for crisping.
- On a large, rimmed baking sheet, toss the halved Brussels sprouts and chopped bacon with the olive oil, salt, and pepper.
- Spread the mixture in a single, even layer. Do not overcrowd the pan, or the sprouts will steam instead of roast. Use two pans if necessary.
- Roast for 25-30 minutes, tossing halfway through, until the sprouts are tender and the outer leaves are deeply browned and crispy.
- If using, drizzle with a sugar-free balsamic glaze just before serving.
Place the Brussels sprouts cut-side down on the baking sheet. This direct contact with the hot pan creates a deep, delicious caramelization.
4. Cheesy Garlic Asparagus Bake
Save this quick and elegant side dish for your holiday menu!
When you need an elegant keto side dish that takes almost no effort, this is your answer. Fresh asparagus spears are tossed with garlic and olive oil, then baked under a blanket of melted mozzarella and Parmesan cheese. It’s simple, fast, and looks incredibly impressive on the holiday table.
Ingredients Needed:
- 1 bunch of fresh asparagus, tough ends trimmed
- 2 tbsp olive oil
- 3 cloves garlic, minced
- 1/2 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- Salt and pepper to taste
Step-by-Step Directions:
- Preheat your oven to 400°F (200°C).
- On a baking sheet or in a shallow baking dish, toss the asparagus spears with olive oil, minced garlic, salt, and pepper.
- Arrange the asparagus in a single layer.
- Bake for 10-12 minutes, until the asparagus is tender-crisp.
- Remove from the oven, sprinkle the mozzarella and Parmesan cheese evenly over the top.
- Return to the oven and bake for another 3-5 minutes, or until the cheese is melted and bubbly. For a browner top, switch to the broiler for the last minute (watch carefully!).
Don’t overcook the asparagus in the first step. It should still have a slight bite before you add the cheese, as it will continue to cook as the cheese melts.
5. Savory Keto Holiday Stuffing
Pin this must-have keto stuffing recipe! You won’t miss the carbs.
Yes, you can have amazing stuffing on a low-carb diet! This recipe uses toasted keto-friendly bread cubes, savory pork sausage, and classic herbs like sage and thyme to perfectly mimic the flavor and texture of traditional holiday stuffing. It’s a game-changer.
Ingredients Needed:
- 6 cups of cubed, day-old keto-friendly bread
- 1 lb pork sausage
- 1 tbsp butter
- 1 large onion, chopped
- 2 celery stalks, chopped
- 2 tsp fresh sage, minced
- 1 tsp fresh thyme, minced
- 1 cup chicken or turkey broth
- Salt and pepper to taste
Step-by-Step Directions:
- Preheat oven to 375°F (190°C). Spread the keto bread cubes on a baking sheet and toast for 10-15 minutes until lightly browned and dry. Set aside.
- In a large skillet, cook the pork sausage over medium heat until browned, breaking it up with a spoon. Drain off any excess grease, leaving about 1 tablespoon in the skillet.
- Add the butter to the skillet. Sauté the onion and celery until softened, about 5-7 minutes. Stir in the sage and thyme and cook for another minute until fragrant.
- In a large bowl, combine the toasted keto bread cubes, cooked sausage, and the vegetable mixture.
- Pour the broth over the mixture and gently toss to combine. Season with salt and pepper.
- Transfer to a greased baking dish and bake for 30 minutes, or until heated through and the top is golden brown.
Make sure your keto bread is very dry and toasted. This helps it absorb the broth without becoming mushy, creating the perfect stuffing texture.
6. Decadent Keto Creamed Spinach
Save this steakhouse-style creamed spinach recipe!
Bring the steakhouse to your Christmas table with this incredibly rich and decadent keto creamed spinach. A simple sauce of cream cheese, heavy cream, and Parmesan, finished with a hint of nutmeg, makes this side dish pure luxury. It’s the perfect keto side for prime rib or turkey.
Ingredients Needed:
- 16 oz fresh spinach (or 10 oz frozen, thawed and squeezed dry)
- 4 oz cream cheese, cubed and softened
- 1/2 cup heavy cream
- 1/4 cup grated Parmesan cheese
- 2 cloves garlic, minced
- Pinch of freshly grated nutmeg
- Salt and pepper to taste
Step-by-Step Directions:
- If using fresh spinach, wilt it in a large pot over medium heat. If using frozen, ensure it is completely thawed and squeezed bone-dry in a cheesecloth or with your hands.
- In a skillet over medium heat, combine the cream cheese, heavy cream, and minced garlic. Stir until the cream cheese is melted and the sauce is smooth.
- Stir in the grated Parmesan cheese and the pinch of nutmeg. Season with salt and pepper.
- Add the dry spinach to the cream sauce and stir until it’s fully coated and heated through.
- Serve immediately.
The most common mistake is not squeezing enough water out of the spinach, leading to a thin sauce. Whether fresh or frozen, squeeze out as much liquid as physically possible for the creamiest result.
7. Roasted Broccoli with Garlic and Parmesan
Pin this super simple, flavor-packed broccoli recipe!
Sometimes the simplest recipes are the best. Roasting broccoli at high heat with garlic and olive oil until it’s tender with crispy, charred edges is a game-changer. Finishing it with Parmesan cheese for the last few minutes of cooking makes it utterly irresistible.
Ingredients Needed:
- 1 large head of broccoli, cut into bite-sized florets
- 3 tbsp olive oil
- 4 cloves garlic, thinly sliced
- 1/3 cup grated Parmesan cheese
- Salt and pepper to taste
- Optional: squeeze of fresh lemon juice
Step-by-Step Directions:
- Preheat oven to 425°F (220°C).
- On a large baking sheet, toss the broccoli florets with olive oil, sliced garlic, salt, and pepper until evenly coated.
- Spread in a single layer, ensuring the florets aren’t crowded.
- Roast for 15 minutes.
- Remove the pan from the oven, sprinkle the Parmesan cheese over the broccoli, and toss gently.
- Return to the oven and roast for another 5-7 minutes, until the broccoli is tender with crispy, charred edges and the cheese is melted and golden.
- Squeeze fresh lemon juice over the top before serving, if desired.
Adding the parmesan cheese in the last 5-7 minutes of cooking prevents it from burning and creates perfectly melted, crispy bits.

Psyllium husk is the magic ingredient for that chewy, bread-like texture. Make sure you use the powder form, not the whole husks, for the best results.

Pin this essential 5-minute keto gravy recipe!
A holiday meal isn’t complete without gravy, but traditional recipes use flour or cornstarch. This keto-friendly gravy uses a tiny pinch of xanthan gum to thicken your flavorful pan drippings into a rich, smooth sauce that’s perfect for pouring over turkey and cauliflower mash.
Ingredients Needed:
- 2 cups pan drippings from your roast, or low-sodium beef/chicken broth
- 2 tbsp butter (optional, for richness)
- 1/4 tsp xanthan gum
- Salt and pepper to taste
Step-by-Step Directions:

- While whisking continuously, slowly and evenly sprinkle the xanthan gum over the simmering liquid.
- Continue to whisk for 1-2 minutes as the gravy begins to thicken. It will thicken further as it cools slightly.
- Be careful not to add too much xanthan gum, as it can become slimy. Start with 1/4 tsp; you can always add a tiny bit more if needed.
- Season with salt and pepper to taste and serve hot.
The key to lump-free xanthan gum gravy is to sprinkle it slowly and evenly while whisking constantly. Don’t just dump it in, or it will clump up immediately.

FAQs About low-carb christmas side dishes
