Ingredients

• ▢ 1/2 tsp olive oil
• ▢ 1 clove crushed garlic
• ▢ cooking spray
• ▢ 1 1/4 cups quinoa, rinsed and drained
• ▢ 18 oz can tomato sauce
• ▢ 2 cups reduced-sodium chicken or vegetable broth*
• ▢ 1 1/2 teaspoons cumin
• ▢ 1 tbsp chipotle en adobo sauce, or more if you want it spicy
• ▢ kosher salt and freshly ground black pepper, to taste
• ▢ 14 oz can diced green chiles
• ▢ 3/4 cup canned black beans, drained and rinsed
• ▢ 3/4 cup fresh or frozen thawed corn
• ▢ 1/4 cup chopped fresh cilantro, plus 2 tbsp for garnish
• ▢ 1 1/2 cups part-skim shredded Mexican cheese blend, divided*
• ▢ 1 medium, 4 oz Haas avocado, diced

* For gluten-free be sure to check the labels.

Equipment

• 1 medium saucepan with lid
• 1 large mixing bowl
• 1 9×9-inch or similar baking dish
• Measuring cups and spoons
• Wooden spoon or spatula

Prep tips

• Rinse the quinoa thoroughly in a fine mesh sieve until the water runs clear; this removes bitter saponins and helps the final bake taste clean and bright.
• Drain and rinse the canned black beans to reduce excess sodium and improve texture.
• If you prefer a milder dish, start with 1/2 tablespoon of the chipotle en adobo sauce and add more after tasting the assembled mixture.
• Use the freshest avocado and cilantro for garnish to keep flavors vibrant at serving time.

Step-by-step instructions

The directions below have been rewritten into clear, sequential steps while keeping ingredient amounts unchanged. Follow them in order for the best results.

1. Preheat your oven to 375°F (190°C). Spray a 9×9-inch or similar baking dish with cooking spray and set it aside so the assembled bake won’t stick while cooking.
2. Heat a small skillet or saucepan over medium-low heat and add 1/2 tsp olive oil. Once the oil shimmers, add the crushed garlic and cook for about 30 seconds to 1 minute, stirring constantly, until fragrant. Do not let it brown; you only want to release the garlic’s aroma.
3. Transfer the rinsed and drained 1 1/4 cups quinoa to the saucepan with the garlic. Add the 18 oz can of tomato sauce and 2 cups reduced-sodium chicken or vegetable broth. Stir in 1 1/2 teaspoons cumin and 1 tablespoon chipotle en adobo sauce. Season with kosher salt and freshly ground black pepper to taste.
4. Bring the mixture to a gentle boil over medium heat, then reduce the heat to low, cover, and let the quinoa simmer for about 15 minutes. Check for doneness: the quinoa should be tender and most of the liquid absorbed. If there’s still a small amount of liquid, leave the lid on and let it rest off the heat for 5 minutes to finish steaming.
5. While the quinoa cooks, drain and rinse 3/4 cup canned black beans and, if using frozen corn, thaw 3/4 cup of corn so it’s ready to mix. Chop 1/4 cup fresh cilantro and set aside 2 tbsp for garnish. Dice the 1 medium (4 oz) Haas avocado and chop 2 tbsp scallions for the final topping.
6. Once the quinoa is cooked and has rested, fluff it gently with a fork in the saucepan. Taste and adjust seasoning with additional kosher salt, black pepper, or chipotle en adobo sauce if you’d like more heat. Keep the mixture warm.
7. In a large mixing bowl, combine the cooked quinoa with the 14 oz can diced green chiles, the drained and rinsed 3/4 cup canned black beans, 3/4 cup fresh or thawed corn, and 1/4 cup chopped fresh cilantro. Stir everything until evenly distributed. Fold in 1 cup of the 1 1/2 cups part-skim shredded Mexican cheese blend so the filling is cheesy and cohesive, reserving the remaining 1/2 cup for the top.
8. Transfer the quinoa mixture to the prepared baking dish, spreading it into an even layer. Sprinkle the reserved 1/2 cup part-skim shredded Mexican cheese blend evenly over the top so the bake will have a golden, melty finish.
9. Place the dish in the preheated 375°F (190°C) oven and bake for 15–20 minutes, or until the cheese on top is melted and bubbly and the casserole is heated through. If you prefer a more browned top, you can switch the oven to broil for 1–2 minutes—watch carefully to prevent burning.
10. Remove the dish from the oven and let it rest for 5 minutes. This brief rest helps the casserole set and makes it easier to slice and serve. Spoon the baked quinoa into bowls or cut into portions in the dish.
11. Top each portion with diced avocado, the reserved 2 tbsp chopped cilantro, and 2 tbsp chopped scallions for freshness and color. Serve immediately—this dish is excellent on its own or alongside a crisp green salad and warm tortillas.

Serving and storage

This Quinoa Fiesta Enchilada Bake serves 4–6 depending on portion size. Leftovers keep well in an airtight container in the refrigerator for up to 4 days. To reheat, warm individual portions in the microwave for 1–2 minutes or in a 350°F (175°C) oven for 10–12 minutes until heated through. If you want to freeze portions, place cooled servings in freezer-safe containers for up to 3 months; thaw overnight in the fridge before reheating.

Easy swaps and add-ins

• If you’d like a plant-forward version, use vegetable broth in place of chicken broth; either option works with the listed quantity and flavor profile.
• Add 1 cup of chopped bell pepper or zucchini to the quinoa mixture for more vegetables—sauté briefly with the garlic before adding the quinoa if you want them softer.
• For a cheesier top, swap the reserved 1/2 cup shredded Mexican cheese blend for a full cup, keeping the total cheese amount at 1 1/2 cups as listed.
• If you prefer no spice, omit the chipotle en adobo sauce and increase the cumin slightly for warm, earthy flavor without heat.

Notes on ingredients

Quinoa cooks up light and fluffy when rinsed to remove its natural coating. The tomato sauce and reduced-sodium broth create a rich, tangy cooking liquid that infuses the grain. Chipotle en adobo adds a signature smoky note—start with the specified 1 tbsp and increase only if you want more kick. Use the part-skim shredded Mexican cheese blend as listed to keep the bake balanced; you’ll get melty pull without excess oiliness.

Flavor profile

This bake balances smoky and tangy notes with fresh, bright garnishes. The quinoa absorbs tomato and broth flavors so each bite tastes cohesive. Black beans and corn contribute texture — tender beans and popping sweetness from corn — while cilantro, scallions, and avocado add brightness and creaminess at the end.
