How to Make Quinoa and Black Bean Casserole Step-by-Step

This casserole is so straightforward to prepare, making it an excellent choice for even novice cooks. Just follow a few easy steps, and you will soon enjoy a hearty, fulfilling meal.

What Ingredients Do You Need?

For this recipe, gather the following ingredients for full flavor:

Quinoa and Black Bean Casserole ingredients
Quinoa1 cup (rinsed)
Vegetable broth2 cups
Black beans1 can (15 oz, rinsed and drained)
Diced tomatoes1 can (14 oz, with juices)
Corn1 cup, fresh or frozen
Onion1 medium, diced
Garlic2 cloves, minced
Cumin1 teaspoon
Chili powder1 teaspoon
Salt and pepperto taste
Shredded cheese1 cup (optional for topping)
Olive oil2 tablespoons
Cilantrofor garnish (optional)

Step 1: Cook the Quinoa

Preheat your oven to 375°F (190°C). In a medium saucepan, combine your rinsed quinoa with the vegetable broth. This step is critical as it allows the quinoa to absorb the flavors and become fluffy. Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer for about 15 minutes, or until all the liquid is absorbed, and the quinoa looks light and fluffy.

Step 2: Sauté the Vegetables

While the quinoa cooks, heat the 2 tablespoons of olive oil in a large skillet over medium heat. Once hot, add the diced onion and let it sauté for about 5 minutes until softened. Next, stir in the minced garlic, cooking it for an additional minute until it’s fragrant. It’s amazing how quickly the kitchen starts to smell delicious!

Step 3: Mix and Bake the Casserole

In a large mixing bowl, combine the cooked quinoa, sautéed onion and garlic, black beans, diced tomatoes, corn, cumin, chili powder, and salt and pepper to taste. Mixing is key here as these flavors complement each other beautifully! Once thoroughly combined, transfer the mixture into a greased 9×13 inch casserole dish. If you’re a cheese lover, now’s the time to sprinkle the shredded cheese evenly over the top.

Cover your casserole with foil and place it in the preheated oven. Bake for 25 minutes to begin with. After that, carefully remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown. Your kitchen will be filled with an aroma that beckons everyone to the dining table!

Once removed from the oven, let the casserole cool for a few minutes before serving. Garnish with fresh cilantro if you like. This step adds a nice pop of color and freshness to each plate.
