Somehow Thanksgiving has snuck up and it’s just over a week away. Friends, the pressure is on to get that menu finalized! Along with this fabulous Vegan Cauliflower Gratin, I have one more side dish and a tasty appetizer to share with you before the big day.
Preparing large meals for the holidays seems to be a little trickier than it was ten years ago. There’s been a rise in food allergies and sensitivities and a lot of people seem to be following some sort of special diet these days. Trying to create a menu that satisfies everyones needs can often be stressful and frustrating, especially if you’re a people pleaser like I am.
At some point you just have to stop and realize that your family and guests aren’t coming and expecting a dinner that should be on the cover of a magazine (at least I hope they aren’t). They’re coming to be together for a day of eating, relaxing and conversation. They’re not coming to judge your cooking skills.
With turkey being the star of the meal, I like to have several side dishes that will appeal to both meat and non-meat eating guests. These Lentil, Wild Rice and Cranberry Stuffed Squash work great as both a side dish or main dish as does this Baked Pumpkin Goat Cheese Risotto. These Cinnamon Maple Mashed Sweet Potatoes and Butternut Squash are a great alternative to the sugar heavy sweet potato casserole.
For a dairy-free and vegan side dish that has all the creaminess of the traditional recipe, I highly recommend making this Vegan Cauliflower Gratin.
What Do I Need to Make the Cauliflower Gratin?
- One head of cauliflower
- Onion
- Garlic
- Arrowroot flour or cornstarch
- Pacific Foods Organic Unsweetened Almond Original
- Nutritional yeast
- Dijon mustard
- Nutmeg, granulated garlic and crushed red pepper flakes
- Panko breadcrumbs, gluten-free if needed
- Sliced almonds
- Vegan cheese, flat leaf parsley, fresh thyme (optional)
What is a Gratin?
The base of a gratin can be almost anything. Most commonly it’s potatoes, but there are many other vegetable versions out there. Cauliflower, squash, brussels sprouts, etc. What makes a gratin a gratin is that it’s baked in a shallow dish and topped with either cheese or breadcrumbs which are broiled in the oven to give it a crispy top layer.
Since we’re keeping this Vegan Cauliflower Gratin dairy-free, I relied on drizzling the panko topping with olive oil to give it that golden brown crispy top. Before adding the panko I also sprinkled on vegan cheese shreds. This is optional, but I will say some vegan cheese brands have come a long way since the first time I tried them.
Now about that creamy plant-based sauce that the cauliflower is nestled in, it’s magical! The three big dairy ingredients used in a gratin are butter, milk and cheese. To keep it dairy-free I substituted the butter for olive oil, which is used to sauté the onion and garlic. To replace the milk I used almond beverage, specifically Pacific Foods Organic Unsweetened Almond Original.
Pacific uses organic almonds in their almond beverage, which are gently roasted. I think the roasting gives it extra flavor and nuttiness, which is what I was looking for in the sauce for this recipe. On top of being a great product for vegan cooking and baking, it’s also the perfect option for other food allergies and sensitivities. Their almond beverages are gluten free, soy free, yeast free, carrageenan free as well as non-GMO.
How Can I Make This Nut-Free?
If you have nut allergies, have no fear, you can still make this gratin! Pacific Foods has several other non-dairy and nut-free beverages that you can substitute the almond beverage with. Their Unsweetened Hemp Original, Organic Oat Original or Organic Unsweetened Soy Original will all work, but note that the flavor will vary slightly depending on what you use. I’m sure it goes without saying, but skip the sliced almonds on top too.
Making this Vegan Cauliflower Gratin is easy. Cut the cauliflower into florets and boil them in water for 5-6 minutes. Mix together panko, nutritional yeast, granulated garlic, salt and pepper for the topping. Next, sauté the onion and garlic in olive oil. Sprinkle the arrowroot or cornstarch over them and stir it in. Pour the almond beverage slowly over the mixture whisking the entire time. You’re making a béchamel sauce like you would for macaroni and cheese.
Once the sauce has thickened, pour it into a blender or food processor and add in the spices, dijon mustard and nutritional yeast. Purée it until it’s smooth and give it a taste. It won’t taste identical to cheese sauce, but the nutritional yeast should give it a “cheesy” flavor. If it’s lacking add a little more.
Put the cauliflower florets into the skillet you made the sauce in and then pour the sauce over the cauliflower. If you’re using vegan cheese shreds add those next and then finish with the panko topping. The gratin will bake for 20-30 minutes or until it’s bubbly and the top is browned. Remove from the oven and top with sliced almonds and chopped fresh parsley and thyme.
Making this cauliflower gratin vegan is easy and requires no extra ingredients. It tastes rich, creamy and slightly nutty and has tons of texture thanks to the crispy panko topping and sliced almonds. It definitely deserves a spot on this year’s Thanksgiving table!
