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 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.
  • 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.
