The Best Cauliflower Stuffing

Swap carb-heavy bread for cauliflower in this simple, delicious, low-carb vegan cauliflower stuffing! It’s gluten-free, grain-free, paleo, keto, vegan, and loaded with veggies!

Flavor-packed low-carb Mushroom and Cauliflower Stuffing

I’ll admit, I love regular bread stuffing. A lot. However, it weighs heavily in my tummy during the holiday when there’s a table of delicious food to make room for. I also often share the holidays with several guests who are gluten-free or otherwise can’t consume bread. That’s where delicious vegan, gluten-free, keto, paleo, and bread-free cauliflower stuffing comes in!

By swapping out the bread for cauliflower, this crowd-pleasing keto stuffing makeover is far lighter (both in calories and carbs) yet still packed with flavor. It’s also super comforting with the addition of poultry seasoning and plenty of vegan butter (or a paleo-friendly fat) for richness. As it fits many dietary requirements, everyone can enjoy it, too, and what’s Thanksgiving without stuffing?

Preparing this vegan stuffing is super simple too. Just chop the veggies, toss them with the seasonings and vegan butter (or oil), and roast everything on a sheet pan in a high-heat oven until tender and lightly caramelized. Using just one pan (two, if they’re small) and a bowl = easy clean-up, too!

The Ingredients

This cauliflower stuffing recipe is made entirely of common veggies and simple pantry basics.

• Cauliflower: Use one medium head of cauliflower. Check FAQs for info on using frozen cauliflower. This is the base for this cauliflower stuffing recipe, soaking up all the surrounding flavors and acting like the bread.
• Mushrooms: I used baby Bella mushrooms this time, but you can experiment with other mushrooms (portobello, cremini, white button, etc.).
• Celery: Feel free to omit it if you aren't a fan of celery or substitute it with leek.
• Onion: I use yellow onion, though white onions or shallots will also work.
• Garlic: Adjust the amount to preference. Use garlic powder in a pinch, but fresh is best.
• Vegan butter: Use your favorite vegan butter for richness and flavor in the cauliflower dressing. Coconut oil or olive oil would also work (and are paleo) but lack the same rich flavor.
• Parsley: For extra color, flavor, and freshness in this homemade vegan stuffing.
• Poultry seasoning: While it has poultry in its name, this seasoning is usually 100% vegan and packed with flavor.
• Salt & black pepper: Season to taste (optional).

What Else Could I Add to Cauliflower Stuffing?

• Carrots: Finely chopped carrots would complete a mirepoix base (celery, onion, and carrot) for extra depth of flavor and color, to the vegan cauliflower stuffing.
• Leek: Finely sliced leek is packed with flavor and a delicious addition to this vegetarian stuffing. You could also use it as a milder onion substitute.
• Cranberries: Cauliflower stuffing with cranberries is delicious. You could soak them in hot veg broth, so they plump up if preferred.
• Herbs: Cauliflower is a flavor magnet, so feel free to add extra flavor depth with fresh (or dried) herbs. I.e., rosemary, sage, thyme, etc.

To hit the notes of regular bread stuffing, I recommend combining thyme and sage (about ½ teaspoon each).

• Pecans: Sprinkle chopped pecans into the vegan Thanksgiving stuffing in the last few minutes of baking so they don’t burn. For a nut-free version, use shelled pumpkin seeds or sunflower seeds.
• Vegan sausage: Chop into small pieces and cook according to the package instructions (i.e., add to the oven with 15-20 minutes of baking time left).
• Nutritional yeast: For a savory, nutty, 'cheesy' flavor. Add a generous pinch and increase to taste.

How to Make Vegan Cauliflower Stuffing?

This vegan stuffing recipe takes less than 15 minutes to prepare from start to finish and follows just 5 simple steps.

• 1) First, preheat the oven to 450F/230C, and line a large baking sheet (or two smaller ones) with parchment paper or a silicone mat.
• 2) Meanwhile, rinse and chop the cauliflower into ½-inch florets, slice the celery into pieces around ¼-inch thick, and slice the mushrooms and onion.

• 3) Combine the chopped vegetables with the garlic, melted vegan butter, and seasoning, and toss well until everything is evenly coated.

• 4) Spread the ingredients in a single layer on the baking sheet/s and bake on the middle rack for 20 minutes. Then, remove it from the oven, stir in the parsley, and bake for a further 15 minutes, or until the vegetables are tender and lightly caramelized. Optionally season with salt and pepper when serving - enjoy!

For more caramelized veggies, increase the baking time slightly. Alternatively, switch on the broiler for a few minutes.

Top Recipe Tips and Notes

• Slice the veggies evenly: That way, they’ll bake evenly.
• To save time: You can purchase pre-sliced mushroom, mirepoix mixture, and cauliflower florets and minimize the prep time to just a few minutes! A mandoline can help speed up chopping done at home.
• For more caramelization: Be careful not to overcrowd the pan. The veggies need airflow to crisp up and caramelize rather than just steam and soften.
• For a crispier top: Broil the vegetarian stuffing for a few minutes at the end of the cooking process.

Storage Recommendations

Make ahead/store: You can prepare this low-carb stuffing up to 4 days in advance and reheat it on the day (though I recommend under-baking it by 5-10 minutes as it will continue to cook when you reheat it). The same goes for storing leftovers - keep them covered or in an airtight container in the fridge for 4-5 days.

Freeze: Allow it to cool and store in a Ziplock/Stasher bag for up to 4 months. Thaw in the fridge overnight before reheating.

Reheat: Transfer the vegan stuffing to an oven-safe dish and bake it for 20-30 minutes at 350F/175C. For smaller portions, you can reheat it, covered, using a microwave at 50% power.

Serving Suggestions

This vegan gluten-free stuffing is perfect for adding to your Thanksgiving table and will pair wonderfully with other Thanksgiving sides, like creamy Instant Pot mashed potatoes, air fryer butternut squash, sprouts, vegan gravy, etc.

However, as it’s also just a delicious veggie side dish, you can serve this with many meals for extra nutrients and flavor!
