Delicious Quinoa Casserole
A hybrid of modern Mexican and Thai cuisines, this black bean quinoa casserole has layers upon layers of flavours that scream “fresh”. Black beans are one of my favorite additions to all kinds of Mexican-inspired dishes including quinoa and black bean salad, black bean salsa, and mango black bean salad! I recently even made black bean nachos!
Combining sauteed vegetables, black beans, cooked quinoa, coconut milk, cheese, cilantro and onion creates delicious black bean casserole that really stands out from any traditional casseroles you are used to. And it’s healthy too!
As all the ingredients are already cooked, you just need to put the assembled casserole in the oven for everything to “marry” each other for 30 minutes. Quinoa makes for a delicious addition to casseroles and one-pot dishes too, like this one-pot quinoa and chicken or ground turkey quinoa casserole.
It tastes even better the next day and is great to freeze and make ahead.
Ingredients for Black Bean Quinoa Casserole
- White or tri-color quinoa: A staple in most healthy pantries. Quinoa is great for using in casseroles because unlike brown rice it is ready in 10 minutes and offers 8 grams of protein and 5 grams of fiber per 1 cup of cooked quinoa.
- Regular or low-fat canned coconut milk: Instead of canned soup, we use canned coconut milk to make casserole saucy. Milk from a carton will not work.
- Black beans, corn, bell pepper: A bulk of flavorful frozen, canned and fresh veggies and legumes for protein and fiber. Here is detailed tutorial how to cook dried beans from scratch.
- Fresh herbs and jalapeno: Lots of cilantro, green onion, and spicy pepper add flavor with little calories.
- Cheese: Gooey melted cheddar, Tex Mex or Colby cheese is a must for this black bean casserole.
How to Make Black Bean Casserole
There is detailed recipe card below.
- Prep: Preheat oven to 350 F degrees and spray 8×11 baking dish with oil.
- Cook quinoa as per package instructions: Or cook 1 1/2 cup of dry quinoa with 3 cups of water for 12 minutes on low heat after boiling. Don’t forget to fluff with a fork. Follow my step by step how to cook quinoa on stove instructions for troubleshooting or use Instant Pot quinoa. If you have leftover cooked quinoa you can use about 4 cups.
- Saute veggies and beans with spices: First cook garlic. Then corn, bell peppers, jalapenos and cumin. DO not stir often to allow veggies to roast becoming more flavorful.
- Combine: In a large mixing bowl, combine cooked quinoa, black beans, herbs, half the cheese, coconut milk and salt. Mix, flatten in baking dish and sprinkle with other half cheese.
- Bake for 30 minutes uncovered: This is when magic happens and flavors “marry each other”.
- Garnish: Sprinkle with remaining 1/4 cup cilantro and 1/4 cup green onions.
Variations and Serving
- Use mixed beans: Instead of black beans, use equal amount of white beans, mixed beans or even chickpeas.
- Substitute for coconut milk: A can of low sodium or no salt added tomato sauce, passata or crushed tomatoes. Casserole will lose its Thai flavor but will stay along the Mexican line. Or use salsa but then reduce salt significantly.
- Other veggies: Feel free to use mushrooms instead of bell pepper. They are very flavorful once sauteed.
- Add protein: If you would like to add meat, add shredded chicken cooked in Instant Pot or pre-browned ground turkey, beef or chicken.
- Do I have to thaw frozen corn? No. Just add it to the skillet and it will defrost quickly.
- Make it vegan and dairy free: Use vegan cheese. Otherwise, all ingredients are plant-based in this quinoa casserole. Woohoo!
- Make burritos: Place about 1 cup of the bean casserole in the center of a flour tortilla, wrap and enjoy!
- Make vegetarian tacos: Serve as filling for tacos with some salsa, sour cream, and avocado or guacamole!
- Side dish: For easy chicken tostadas!
How to Store, Make Ahead and Reheat
Store: Refrigerate in an airtight container or in baking dish covered with wrap for up to 3 days. Or freeze leftovers for up to 3 months. Use leftovers to make veggie quesadillas!
Freeze uncooked: Assemble, tightly wrap with plastic and then foil, and freeze for up to 3 months. Thaw in the fridge overnight and bake as per instructions + 15 minutes.
Make Ahead: Assemble, cover and refrigerate for up to 48 hours. Bake as per instructions.

Absolutely delicious!
I didn’t have enough bell pepper so cleaned fridge and completed with zucchini, mushrooms and snow peas, yumm! Happy we have leftovers.
I’ve even been able to sneak in 1 teaspoon of cumin and hubby didn’t find out, it’s a first, a victory! 😅
Love that you threw in the veggies you had on hand! That’s my kind of cooking!
What can I use to replace the coconut milk?
Canned soup.
This turned out better than I had ever imagined. The whole family loved it. I substituted the black beans with a variety of beans.
Awesome Mireille! Thanks for sharing!
Wow it was wonderful, many thanks for providing such a lovely menu. My daughter is vegetarian so a no-brainer for her but my son traditionally hates anything veggie, however he loved this and wanted more!
I live in Barcelona so some simple ingredients like tinned black beans are hard to find, I had to use dried ones soaked and then cooked. Of course, I prepared far to many beans, so I’ll be investigating your other black bean recipes today.
Hi Nick! I am so glad to hear this was a hit with both of your kids!
I love making large batches of black beans. Did you know you can freeze them?

I used salsa in place of coconut milk and vegan cheese. Really good.
So happy to hear this Shana!
I have a question. How many cups of cooked quinoa would you use? Thank you so much.
4.5 cups cooked quinoa.
This was my first time cooking with Quinoa. It was delicious, healthy and will definitely be making it again in near future. I used sweetened condensed coconut milk as that’s all I could find. Not sure if that is what was meant for the recipe or not. I liked the sweet taste it added. Next time will look at adding chicken or turkey to it and topping with Sour Cream. Definitely a recipe keeper!
Glad you enjoyed this quinoa recipe Angie!
It sounds wonderful but can I use regular milk in place of cocoa milk? Or, do you have another suggestion to replace the coconut milk? Thank you
Regular milk will not work. You can replace canned coconut milk with tomato sauce or diced tomatoes (both low sodium) or use 1/2 cup more broth.
So yummy.
Thank you for your wonderful review, Lara!
It’s sound pretty good will do it tomorrow.
Hope you enjoy.
