Why This Recipe Works 

This recipe is much healthier than traditional broccoli rice casseroles that are often loaded with cream, butter, and cheese.

It’s 100 percent vegan, gluten-free, and super comforting. 

Instead of dairy products the recipe calls for a combination of unsweetened almond milk, cashews, nutritional yeast, and miso paste that are blended into a creamy sauce. 

Cashews are the perfect base for dairy-free cream sauces. Nutritional yeast and miso paste provide the sauce with a cheesy and nutty taste. 

Vegan cheese shreds add a creamy crust that makes this recipe even more comforting. It’s perfect for the whole family and kids love it! 

Ingredients That Go Into This Recipe:

  • Cooked Brown Rice – for example from the day before 
  • Cashews – unsalted and not roasted 
  • Almond Milk – make sure to use unsweetened milk. You could also use soy milk 
  • Nutritional Yeast – it has a cheesy and nutty taste and is perfect for this recipe 
  • Miso Paste – you could use white or yellow miso paste 
  • Mustard – I recommend Dijon mustard 
  • Vegan Cheese – use your favorite vegan cheese shreds 

How To Make This Recipe  

The recipe is pretty easy! The actual preparation time is rather short. It takes about 10 minutes to prepare and another 15 minutes in the oven.

1. Step: Preheat your oven to 350 °F. Grease a large baking dish with vegan margarine. Heat some oil in a pan and sauté the chopped onion until it’s translucent. This should take about 3 minutes. 

2. Step: Place all of the ingredients for the sauce into a high speed blender.

3. Step: Process until smooth. 

4. Step: Wash the broccoli and cut it into florets. Cook the broccoli either on the stovetop or in an Instant Pot (choose “0 minutes” on manual).

 8. Step: Transfer to the prepared baking dish.

Recipe Notes: 

  • I used brown rice for my casserole to make it healthier. However, it also works with regular white rice.
  • It’s best to make the rice the night before. This way the preparation time will be much shorter. 
  • I highly recommend using a high speed blender to make the sauce. It won’t get as creamy in a regular blender as the cashews are hard to blend. 
  • As I used my Vitamix to make the sauce, I did not soak the cashews. I don’t think it’s necessary if you use a really good high speed blender. However, if you want to make it a bit easier for your blender, you could soak them in hot water for 30 minutes or even overnight.
