You’ll love this Roasted Butternut Squash Cauliflower Salad for fall. It’s tossed with an easy and very delicious vegan dressing.
Roasted butternut squash is one of my favorite ways to cook and eat this fall veggie. When you toss it with olive oil, salt, and pepper and leave it in the oven for 20 minutes, you have the perfect veggie to enjoy in salads like this Roasted Butternut Squash Cauliflower Salad I’m sharing with you today.
Cauliflowers are also one of my favorite vegetables, especially because they are very versatile. I mean… Have you made/had cauliflower rice before? And what about cauliflower tots? Or cauliflower bites? Or cauliflower pizza crust? Or one-pan cauliflower curry? Or even mashed cauliflower? Mm… My mouth always waters just by thinking about all these delicious recipes we can make with cauliflower.
Butternut squash also lasts so long that I recommend always have on hand to use on last-minute recipes like this Rice with Roasted Butternut Squash and Dried Cranberries, Ground Beef Butternut Squash Meal Prep Bowls, and Roasted Butternut Squash Recipe.
I also think cauliflower goes really well with lots of other veggies, such as butternut squash. This combination of the cauliflower and the butternut squash makes it a perfect side for fall. And if you pair this Roasted Butternut Squash Cauliflower Salad with some type of protein such as eggs, chicken, or even some chickpeas (for vegetarian/vegan option) it becomes a really substantial/complete meal.
Let’s not forget to talk a little bit about the vegan dressing. I made this dressing with only 3 ingredients (I don’t consider salt and black pepper to be an ingredient). It has veganaise, which is a vegan version of the traditional mayonnaise, some Dijon mustard, and garlic. So simple, but so good!
I don’t need to say if you prefer can use the traditional mayo for this recipe. It will be good anyway. Also, this dressing recipe is perfect with the traditional potato salad or my cauliflower “potato” salad.
This is definitely an amazing salad to celebrate fall flavors because it’s simple and quick to make.

Ingredients
For the salad
- 1 medium cauliflower head cut into florets
- 1 small butternut squash peeled and cut in cubes
- 1 tbsp olive oil
- salt and black pepper
- ¼ cup red onion chopped
- 1 tablespoon green onions chopped
For dressing
- 1/2 cup vegenaise or traditional mayonnaise
- 2 tablespoon yellow mustard
- 1 teaspoon garlic minced
- Salt and pepper
Instructions
- First, steam the head of cauliflower. In a large pot add about 2 cups of water and place a steamer basket in the bottom.
- Bring the water to a boil. Add the cauliflower florets into the steamer basket.
- Cover the pot and steam until the cauliflower florets are tender 6-8 minutes. The time will depend on how tender you prefer your cauliflower florets to be.
- Remove from the heat and also remove the lid from the pot. Let the cauliflower cool down for 5 minutes.
- While the cauliflower florets are been steamed, roast the butternut squash. Preheat oven to 400 degrees. On a baking sheet lined with parchment paper or silicone mat, place butternut squash and toss in olive oil and season with salt and black pepper. Mix well to combine.
- Roast in the oven for 15-20 minutes (It'll depend on the size of the butternut squash diced).
- Place the steamed cauliflower, the roasted butternut squash and the red onions in a bowl.
- In a small glass bowl, add all the ingredients for the dressing and whisk everything together to combine.
- Taste to check the seasoning and pour over the salad.
- Mix all the ingredients together until well combined and garnish it with green onions.
Tips
- If you have trouble cutting the butternut squash, you can microwave it for a few minutes to help soften it.
- You can buy pre-cut butternut squash and cauliflower.
- You can soak the red onions in cold water to mellow it out before adding it to the salad.
- To store: Keep this recipe refrigerated for up to 4 days. When serving, do not leave it out at room temperature for too long.

Did you put the dressing on while the veggies were still warm or did you wait until they cooled completely?

Patty Kenner says
Can you make this and then warm it up?
Olivia Ribas says
This recipe shouldn’t be warmed up because it contains mayo. It’s supposed to be served cold.
