Noteworthy ingredients and substitutions
- Leeks, shallots and garlic: add a savory flavor with a touch of sweetness from the caramelized leeks. The leeks or shallots can be substituted with onions or omitted if you prefer not to have a savory depth to your vegan cream sauce. You can also bump up the amount of garlic if you enjoy that pungent punch.
- Cauliflower: will cook quickly when roughly chopped into small florets. You can also use frozen cauliflower rice or frozen cauliflower. Note that large pieces of frozen cauliflower may take longer to soften.
- Nutritional yeast: helps to thicken the sauce and adds a cheesy flavor.
- Vegetable broth: adds nutrients and flavor.
- Lemon: added with a squeeze when serving gives a vibrant fresh flavor to the cauliflower sauce.
- Coconut milk: is completely optional. The sauce will be creamy without it but it's only a small amount and does add a more luxurious creaminess to the sauce.

How to make vegan cauliflower cream sauce
Warm oil in a large sauté pan or skillet over medium-low heat. Add leeks and shallots and sprinkle with salt. Cook for 10-20 minutes, stirring every so often, until the onions just begin to caramelize. Lower heat to low if they are cooking too quickly. Before removing from heat, add garlic and cook until fragrant, about 1 minute.
Tip: If the leeks and onions begin to dry in the pan, add a splash of water or broth, about 1 tablespoon or less at a time, so they don't burn.
Meanwhile, add the cauliflower to a large pot of boiling water. Cook on medium-high heat until fork tender, about 10 minutes. Drain.
Transfer the cauliflower to a high speed blender, add leek mixture, nutritional yeast, vegetable broth and coconut milk if using. Blend on high for several minutes until the sauce is very smooth.
If using a food processor to blend ingredients you may need to stop and scrape down the sides frequently to make sure all ingredients are well blended.
Tip: If you only have an immersion blender, return the cauliflower to the pot, add the leek and shallot mixture and the rest of the ingredients and blend. The sauce may not be as creamy as it would in a blender.
Tips, tricks and variations
- Chop you leeks and shallots into smaller pieces to help them brown quicker. Keep an eye on the heat. There should only be a slight sizzle sound. Turn the heat to low if you feel the onions are cooking too quickly and may burn. You can also add a small splash of water or broth if the pan is drying out, about 1 tablespoon or less at a time.
- If you don't want to use coconut milk than leave it out. It does add a little extra creaminess but you'll still have a velvety sauce without coconut milk.
- The sauce works really well as a vegan alfredo sauce for a simple pasta dish. Add it to your favorite gluten-free pasta with extras like peas, mushrooms or pepper. Or, add some protein with edamame, meat, fish, chickpeas, beans or cooked lentils.
