For many, Thanksgiving means planning a magnificent feast, and this year, we’re bringing you a side dish that promises to steal the show – a delightful Vegan Broccoli Gratin. It feels like only yesterday we were celebrating the last holiday season, yet here we are, already deep into November, making plans for another memorable occasion.

My digital notebook is brimming with links to favorite recipes and a meticulously organized grocery list, ensuring every detail is covered. It’s a joy to curate a menu that caters to everyone, especially when diverse dietary needs are at the table.
In my family, Thanksgiving presents a wonderful culinary challenge: my dad and I embrace a plant-based lifestyle, and my sister, dad, and I are all gluten-free. While we gather with the whole family, crafting our own specialized dishes has become a cherished tradition. Fortunately, I absolutely adore taking charge of our gluten-free, vegan Thanksgiving spread, creating dishes that are not only delicious but also inclusive.
There’s immense satisfaction in preparing a hearty, flavorful meal to share. And let’s be honest, my plant-based, gluten-free creations are often so packed with love and flavor that even the meat-eaters and gluten-lovers at the table find themselves reaching for our “special” food. That, in my book, is a true win!
This Vegan Broccoli Gratin was designed with everyone in mind. Its richness and comforting appeal ensure that every guest at our Thanksgiving table will want a generous serving. Moreover, it proudly caters to our plant-based and gluten-free preferences, making it a truly inclusive dish for all “difficult” eaters and beyond.
The “Cheesy” Secret: Unpacking This Irresistible Vegan Broccoli Gratin
I have a deep appreciation for a well-made broccoli dish – a fact evident from the numerous broccoli recipes on my site. But what truly elevates broccoli, in my opinion, is when it’s enveloped in a luscious, cheesy sauce. Having embraced a dairy-free lifestyle for quite some time, I found immense joy in perfecting a “cheeze” sauce that rivals its dairy counterpart. This Vegan Broccoli Gratin is the culmination of that passion, delivering all the familiar comfort and flavor without any dairy.
The magic of this sauce lies in its surprisingly humble, yet incredibly potent, vegetable-based ingredients. You might be shocked to discover its wholesome origins once you taste its profound richness and creamy texture. The star of this velvety sauce is the humble potato, lending an unparalleled creaminess. Alongside it, cashews contribute additional body and smoothness, while nutritional yeast delivers that essential, savory, umami-rich “cheesy” flavor that makes this gratin truly unforgettable. A blend of carefully selected spices rounds out the profile, creating a depth of flavor that will impress even the most discerning palates.
Once this incredible sauce is prepared, it’s generously combined with tender broccoli florets and transferred to a casserole dish. A sprinkle of high-quality vegan parmesan cheese (my personal favorite comes from Kelly’s Croutons, a fantastic local San Diego company whose products I often find at the farmer’s market or order directly from their site) creates a perfectly golden, crispy topping when baked. The result is a dairy-free gratin that’s so incredibly delicious, you’ll wonder why you ever needed traditional cheese.
One of the best features of this Vegan Broccoli Gratin is its adaptability to holiday meal prep. You can easily assemble it ahead of time and pop it into the fridge, ready to bake when you need it. This convenience is a lifesaver during the busy holiday season, allowing you more time to enjoy with loved ones. I genuinely hope this holiday side dish brings as much joy and deliciousness to your table as it does to mine. Enjoy, and happy holidays, my friends!

Vegan Broccoli Gratin
Pin Recipe
Ingredients
- 1 large russet potato, peeled and diced (should be about 1½ cups after dicing)
- 1 white onion, diced and divided in half
- 2 garlic cloves, peeled
- ½ cup raw cashews, soaked in water for at least 30 minutes and drained before using
- ¼ cup unsweetened non-dairy milk (I used cashew milk)
- ¼ cup nutritional yeast flakes
- 1 tablespoon fresh lemon juice
- 1 teaspoon kosher salt, or more to taste
- ¼ teaspoon turmeric
- ¼ teaspoon paprika
- ¼ teaspoon mustard powder
- 8 cups fresh broccoli florets
- ¼ cup vegan parmesan (I use Kelly’s Croutons Vegan Parmesan)
Instructions
- Preheat the oven to 350°F (175°C) and lightly grease an 8-inch baking dish with avocado oil.
- Bring several cups of water to a boil in a small saucepan. Place the chopped potato and half of the diced onion in the boiling water. Cook for approximately 15 minutes, or until the vegetables are tender and soft enough to be easily blended.
- Once the potatoes and onions are soft, use a slotted spoon to carefully remove them from the cooking water and transfer them into your blender.
- Add ¾ cup of the reserved cooking water to the blender, along with the peeled garlic cloves, the soaked and drained cashews, your chosen dairy-free milk, nutritional yeast, fresh lemon juice, kosher salt, turmeric, paprika, and mustard powder. Blend until the mixture is completely smooth and creamy.
- In a large mixing bowl, combine the fresh broccoli florets with the remaining diced onion. Pour the prepared “cheesy” sauce over the broccoli and onion mixture. Stir thoroughly to ensure all the broccoli and onion are evenly coated in the rich sauce.
- Transfer the sauced broccoli mixture to the greased baking dish. Evenly sprinkle the vegan parmesan over the top. Bake for 30 minutes, or until the gratin is golden brown and bubbling on top.
- Serve hot directly from the oven. Any leftovers can be stored in an airtight container in the refrigerator for up to 5 days.
Expert Tips for the Best Vegan Broccoli Gratin
Achieving the perfect Vegan Broccoli Gratin is simple with a few insider tips. These suggestions will help you maximize flavor, optimize texture, and streamline your cooking process, ensuring a consistently delicious result every time.
- Cashew Soaking is Crucial: For the creamiest, smoothest “cheeze” sauce, don’t skip soaking the cashews. Soaking softens them, allowing them to blend into a truly silky texture. If you’re short on time, a quick soak works too: boil cashews for 10-15 minutes, then drain.
- Mind Your Broccoli Texture: Avoid overcooking the broccoli before adding it to the gratin. You want it tender-crisp, not mushy. It will continue to cook in the oven, so slightly undercooked broccoli at the mixing stage ensures a pleasant bite in the final dish.
- Customize with Confidence: Feel free to experiment with additional vegetables. Sautéed mushrooms, fresh spinach, or even thinly sliced carrots can be lovely additions. A pinch of cayenne pepper can add a subtle kick if you enjoy a little heat.
- Salt to Taste: Remember that “cheesy” sauces often benefit from a good balance of salt. Start with the recommended amount and adjust after blending, as nutritional yeast itself can be quite savory.
Make Ahead & Storage Solutions for Your Convenience
One of the many benefits of this Vegan Broccoli Gratin is its flexibility for meal planning, especially during the busy holiday season. You can prepare it largely in advance, saving you precious time when it matters most.
To make ahead, prepare the broccoli and the “cheesy” sauce as instructed, then combine them in your baking dish and top with vegan parmesan. Cover the dish tightly with plastic wrap or foil and refrigerate for up to 24-48 hours. When you’re ready to bake, remove it from the fridge 30 minutes before baking to allow it to come closer to room temperature, then bake as directed. You might need to add an extra 5-10 minutes to the baking time if it’s still quite cold.
Leftovers of the baked gratin store wonderfully. Simply transfer any remaining portions to an airtight container and keep it in the refrigerator for up to 5 days. To reheat, you can use the microwave for individual servings or warm it in the oven at 300°F (150°C) until heated through, approximately 15-20 minutes, covering it loosely with foil to prevent excessive browning.
