How to make vegan broccoli casserole
The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.
You will want to make the 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 nachos, hash brown casserole, and dairy-free scalloped potatoes.
STEP #1: Making the cheese sauce is as simple as boiling a pot of potatoes, onions, and carrots, adding them to a blender with spices, and blending 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 leftovers to try with other recipes. Once the cheese sauce is complete, set it to the side.
STEP #2: Fully cook the brown rice according to the package instructions. You can use your rice cooker or stovetop, but I have a terrific recipe for flawless Instant Pot brown rice that is quick and ideal for this casserole.
You will also need to go ahead and drain and rinse the chickpeas. I do this by pouring them into a colander in my sink and running cool water over them.
I also have a recipe for Instant Pot chickpeas if you would like to cook your own from dry. They don’t even need to be soaked before cooking.
STEP #3: 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.
STEP #4: 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.
STEP #5: 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.
STEP #6: 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.
STEP #7: Place in oven and bake for 25 minutes. If making in a slow cooker, set it to low and allow it to cook for approximately 1-1/2 hours.
STEP #8: Once completely cooked, remove from oven and allow to cool a bit. Serve warm and enjoy!

Can portions of this recipe be frozen? Thank you.
Joyce- I have not frozen it before but think it should do pretty well.
Made the casserole, it was good! How long will it keep in the refrigerator?
Hi Gray- I’m so glad that you liked the casserole. I should keep in the refrigerator for about 3 days if it’s covered well.
Would it work to substitute half of the rice for riced cauliflower, do you think?
Hi Amelia- Though I haven’t tried that sub myself, I do believe it should work just fine. Good luck!
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 Jack- Thanks so much for the great feedback! This is one of my personal favorites too. 🙂
This is probably the best casserole recipe I’ve found. It’s delicious and has a lot of great flavor!
Should I salt my rice? Making this right now for Thanksgiving!!
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. 🤷🏻♀️
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!!
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.
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!!
