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.

The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.

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 with 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 vegan bean nachoshash brown casserole, and dairy-free 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), and 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 the 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.

I am often asked which knives I use personally, and I have to say that it is Victorinox. They are the same company that makes Swiss Army Knives and the quality is excellent.

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.

Mix thoroughly and remove from heat.

Pour the 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 25 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!

We have several vegan casseroles that you might want to try like our vegan hash brown casserole and healthy dairy-free sweet potato casserole.

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

    1. 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.

  1. 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!

  2. 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. 🤷🏻‍♀️

  3. Hi,
    We were confused on the rice. Do we cook 3 cups of raw rice to make the recipe? Or do we cook enough raw rice to yield 3 cups of cooked rice?
    Same with the chick peas. I bought a can, so do I just measure out 1 cup of the chickpeas?
    Thank you so much!!

    1. Hi Sue- For this recipe, the rice and chickpea ingredients do need to be cooked before adding them to this casserole. That would be 3 cups cooked rice (which should be about 1.5 cups before cooked) and 1 cup cooked chickpeas. Since you are using canned chickpeas, they are already cooked and ready to measure out and add.

  4. I have been making this casserole about once a month for the past year. It is by far my favorite vegan recipe that I have found! It is filling, healthy and most of all it is 10 star delicious!!! Thank you for so many great recipes Terri!!

  5. Hi Terri i to stumbled upon your recipe boy am i glad i did, could not stop eating it the grand kids also loved it. I will keep this recipeThanks so much
