Vegan Broccoli Casserole

When the holidays roll around, it’s pretty common for people to throw caution to the wind when it comes to food and drinks. However, when it comes to being vegan, there’s no throwing your heart to the wind. That’s why recipes like this vegan broccoli casserole, my Butternut Squash Mac and Cheese, and my Olive Oil Mashed Potatoes are a delicious must! No, you’re not sacrificing that flavor, you’re not missing out at all!

It’s really easy to make and I promise it’s not complicated in the slightest. It’s one of the easiest recipes you’ll be making for the holidays, I guarantee it! Really, it’s so good that those who don’t normally eat vegan will devour it without even realizing anything has changed. There’s something extremely satisfying about that aspect of it, ha!

How to Make Vegan Broccoli Casserole for Thanksgiving and Christmas

  1. Prep – Steam or boil the broccoli until just cooked, not mushy, and set aside. Saute the onion until translucent in a skillet.
  2. Add mushrooms – Along with the sea salt and cook until wilted. Add the white wine and thyme. Cook until the liquid has mostly evaporated.
  3. Mix remaining ingredients – In a medium bowl, combine all the ingredients, except the broccoli, and mix well. Add to the pan of mushrooms.
  4. Simmer – Simmer until thickened and then add broccoli.
  5. Bake – Transfer mixture to a casserole dish, top with desired toppings, and broil for a few minutes. Enjoy!

Tips and Variations

  • Storage – Store in an airtight container inside the fridge for up to 3 days. Store in the same type of container in the freezer for up to one month.
  • Reheating – Reheat this dish by placing it in an oven-safe dish and cooking until heated through. You can also use the microwave for a quicker option.
  • WFPB + Plantricious compliance – Use water in place of the oil for this type of compliance.
  • Topping Suggestions – There are quite a few toppings you could use for this dish. Some of my favorites are crispy onions, salty crackers, panko bread crumbs, crushed corn flake cereal, etc.
  • Add soy curls – These are a great way to add more protein to the recipe. They also function as a nice vegan chicken option.
  • More add-ins – You can add in cooked rice such as brown or wild rice, farro, quinoa, or even plant-based cheese to “beef” it up even further.
  • Make it gluten-free – You can swap out the flour for rice flour or chickpea flour to make this entirely gluten-free.

How Much Rice for Broccoli Casserole?

If you’re wanting to add rice to your casserole, I often stick with about 1 cup of wild rice. However, if you want to add more rice, that’s up to you, it just might dry out the recipe if you don’t compensate. So you’ll want to add more liquid to the recipe if you’re adding in a lot more rice. You also want the rice to already be cooked before adding it in.

What to Serve with Broccoli Casserole?

This delicious dish can be served as a side along most main dishes. It’s a staple holiday traditional dish, which means it definitely sits alongside all those holiday dinner classics like the Best Vegan Mac and Cheese,Classic Bread Stuffing and Thanksgiving Vegan Holiday Roast, flawlessly. Of course, it goes well with dinners outside of the holidays as well. Some of my favorite dishes to serve it with are these Vegan Steaks, Meatless Ribs, Paprika Potatoes, Roasted Cauliflower Steaks, Vegan Flatbreads, Tofu Scramble, etc.

Truth be told you could totally serve this vegan broccoli casserole on its own as it’s hearty enough. Plus, it’s easy and healthy making for a satisfying recipe in general. Add in some rehydrated and pan seared soy curls for more protein or even rice to “beef” it up for a stand alone dish.
