Flavorful cauliflower stuffing is made with cauliflower, celery and portobello mushrooms and roasted in the oven. It’s healthy and tasty!
I was so happy when I served this healthy stuffing to my family and they gobbled it all up! I was actually planning on having leftovers for the next day – no such luck. But it was worth it!
Now I know that the next time I make this cauliflower stuffing, I should most definitely double the recipe, to ensure I have some tasty leftovers.
A healthy substitute for bread stuffing
I used to make traditional bread stuffing for Thanksgiving that we all loved. When my husband and I transitioned to a low carb diet, 5 years ago, I had to find a replacement.
This sausage stuffing is wonderful. But one of our usual Thanksgiving guests doesn’t eat pork, so I wanted to find a vegetarian substitute.
This cauliflower stuffing is just what I was looking for. A healthy and wonderfully flavorful side dish, reminiscent of traditional stuffing but keto and paleo.
In fact, it’s so good that I plan on serving it year-round. There’s no point in serving something so good just once a year.
The only downside: it’s a lot of work to chop so many vegetables! The cooking itself is a breeze – I make this recipe in the oven. But the prep work is somewhat time-consuming. I do think the end result is worth it, though.
Apart from the cauliflower, I use onions, celery and chopped portobello mushrooms in this recipe. All of these add wonderful layers of flavor and texture to the stuffing.
The ingredients you’ll need
Here’s an overview of the ingredients you’ll need to make this tasty side dish. The exact measurements are listed in the recipe card below:
Fresh cauliflower: Cut it into bite-size pieces. I haven’t tried making this recipe with frozen cauliflower, but I suspect that fresh is the way to go.
Vegetables: Chopped onion, sliced celery, and chopped portobello mushrooms.
Minced garlic: Mince it yourself or use the stuff that comes in a jar. Freshly minced is probably better, but I’m lazy, so you know what my choice is…
Melted butter: You can use olive oil instead if you wish.
Kosher salt and black pepper: If using fine salt, you should use less of it.
Spices: Dried thyme and dried sage. Make sure they are fresh. Spices are delicious and healthy, but a stale spice can easily ruin a dish!
Olive oil spray: I use it to spray the dish midway through roasting. Olive oil is a delicious and healthy oil. But if you’re unsure about cooking with it, you can use avocado oil instead.
Chopped parsley: This is mostly for garnish. Without it, the dish isn’t very colorful.
How to make cauliflower stuffing
Apart from the tedious work of chopping the vegetables, this is not a difficult recipe. The detailed instructions are included in the recipe card below. Here are the basic steps:
Toss the vegetables except for the mushrooms with the melted butter and the spices.
Roast them for 15 minutes at 450°F.
Add the mushrooms and roast for 15 more minutes.
Garnish with parsley and serve.
Butter or olive oil?
I use quite a lot of butter in this cauliflower stuffing – 6 tablespoons. It’s delicious, of course, and I don’t find it excessive for 8 people (that’s less than a tablespoon per person). But if you prefer, you could try using just 4 tablespoons.
You can also use olive oil instead of butter. It’s delicious and it’s also a very healthy choice. Personally, I’m partial to butter.
What to do with leftovers?
If you are fortunate enough to have leftovers, they keep just fine for 3-4 days in the fridge, in an airtight container. Reheat them in the microwave, covered, on 50% power.
You can also make this cauliflower stuffing ahead of time, then on Thanksgiving day reheat it in a 350-degree oven.

Cauliflower Stuffing
INGREDIENTS
- 1 medium head cauliflower, cut into bite size pieces (2 lb. whole, 1 lb. after trimming)
- 1 medium onion, chopped (6 oz)
- 1/2 cup thinly sliced celery
- 1 tablespoon minced garlic
- 6 tablespoons unsalted butter, melted
- 2 teaspoons coarse kosher salt, divided (not fine salt)
- 1/4 teaspoon black pepper
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried sage
- 2 Portobello mushrooms, chopped (10 oz)
- Olive oil spray
- 2 tablespoons chopped parsley for garnish
INSTRUCTIONS
- Preheat the oven to 450 degrees F. Line a large rimmed baking sheet with parchment paper.
- In a large bowl, stir together the chopped cauliflower, onion, celery and garlic. Toss with the melted butter, 1 teaspoon kosher salt, black pepper, thyme and sage.
- Spread the cauliflower mixture on the prepared baking sheet. Roast for 15 minutes.
- Remove the pan from the oven. Add the chopped mushrooms, stirring them into the mixture. Sprinkle with the remaining teaspoon of salt and lightly spray with olive oil.
- Return the pan to the oven and roast until the stuffing is browned, about 15 more minutes. To promote browning, if your pan is broiler-safe, you can also roast for just 10 minutes, then broil, 6 inches below the heating element (not directly below or it will burn), for 2-3 more minutes.
- Garnish the cauliflower stuffing with chopped parsley and serve.
