This broccoli casserole with rice was inspired by a recipe I came across from Susan Voisin with Fat-Free Vegan Kitchen. Since I have my own Creamy Vegan Cheese Sauce, I used it and tweaked a few of the spices to make this delicious, broccoli rice recipe that keeps the whole family happy.

We love this vegan casserole because it’s…

  • Perfect for family gatherings
  • Easy to make a day ahead
  • Can even be made in a crockpot
  • Vegetable-Packed
  • Super filling
  • Crowd-pleasing
  • Simply delicious

Both my husband and I come from big families that get together for lunch after church on Sundays. Everyone brings a couple of dishes, and we enjoy time eating, laughing, and playing with the kids and grandkids. Casseroles are perfect for those kinds of days!

How to make vegan broccoli casserole

This healthy broccoli casserole takes just a little bit of time to prepare and is well worth the effort.

Making vegan cheese sauce

Personally, I think the magic ingredient is my Creamy Vegan Cheese Sauce because it adds such a nutty, cheesy, creamy texture and taste. Not only is it combined in the actual ingredients, but it’s also drizzled over the top before baking.

You will want to make this cheese sauce first thing. It’s really easy to make and even freezes well. I usually already have some on hand in my freezer which shortens the steps to making any of my recipes that require cheese such as nachoshash brown casserole, and scalloped potatoes.

Making this terrific cheese sauce is as simple as boiling a pot of potatoes, onions, and carrots, adding them to a blender with cashews (or white beans), spices, and blending it until smooth.

I have a Vitamix blender and so don’t take the time to soak my cashews. That thing is powerful and everything that goes into it comes out creamy. However, if your blender isn’t jet engine speed, soaking the cashews in warm water for at least 30-minutes before adding to this recipe will help this recipe come out more creamy. 

This recipe makes a little more sauce than you actually need for the casserole, so you’ll have some leftover to try with other recipes.

Once the cheese sauce is complete, set it to the side.

Making the broccoli casserole

Begin by fully cooking the brown rice and, if you aren’t using already cooked canned chickpeas, you will need to cook the beans as well.

Preheat oven to 350°F and line a 9″ x 13″ baking dish with parchment paper. If making in a crockpot, select low heat.

Dice the veggies that you’re going to need for this recipe.

In a medium-sized saucepan, saute the onion, garlic, red bell pepper, and celery in veggie broth. Cook until slightly tender, approximately 3 minutes.

Add the broccoli florets and cook for another 3 minutes.

Stir in cooked chickpeas, brown rice, 2 cups of cheese sauce, almonds (if using), and spices. Save the remaining 1 cup of cheese sauce for topping.

Pour mixture into the prepared baking dish, pressing in with a spoon to fill the pan. Drizzle the remaining 1 cup of cheese sauce over the top. I like to sprinkle a little more smoked paprika on top.

Place in oven and bake for 30 minutes. If making in a slow cooker, set to low and allow to cook for approximately 1-1/2 hours.

Once completely cooked, remove from oven and allow to cool a bit. Serve warm and enjoy!

Vegan casseroles

Vegan casseroles just make things easier! I can put this casserole together a day ahead and just pop it in the oven Sunday morning without all of the fuss, rushing around, and clean up. It makes the day more enjoyable, and unhurried time with family is precious!

If preferred, it can even be cooking in a crockpot. That way you can leave and go to church or to do errands and come back to a fully cooked dish ready to eat.

  • Use any leftover cheese sauce on baked potatoes, steamed veggies, pizza, and anything else you can think of.
  • Cheese sauce keeps in the refrigerator in an airtight container for 7+ days.

Can you tell me what a dry steak seasoning is and where to get that?

Hi Tess- It's a mixture of different dry seasonings that are often used as a steak ruf. It can usually be found as a blend in the spice section of many grocery stores.

Amazing recipe!! Turned out absolutely phenomenal. The spices and flavors were just great. I found I needed more liquid when blending my cheez sauce (partially because I used more cashews than the recipe called for, cause I didn't want leftover cashews) but I didn't have enough cook water from the veggies, so I used store-bought veg stock instead, still tasted great. I also needed more broth to cook the veggies that go in the casserole, but that might be because I used a really big pan and it evaporated fast. I topped it with some Daiya cheddar shreds in the last ~10 minutes of baking for a little extra cheeziness! It's so good! Mom and I demolished over half the pan for dinner. Thanks for this!

Hi Alex- I don't specifically salt the rice but do add it to the casserole mix while combining it before baking.

Just made this today and it is REALLY good. I followed the instructions exactly for both the casserole and the cheese sauce (which is awesome BtW) but I only ended up with a bit over two cups of the sauce, enough for the recipe and a tiny bit to drizzle on the top. I kept reading and re-reading the list of ingredients and I did not leave anything out or under measure so I’m not sure what happened. Next time I’ll double the sauce ingredients. 🤷🏻‍♀️
