Cheesy quinoa bake is mac and cheese's wholesome cousin — fluffy quinoa suspended in an egg-and-milk custard with sweet bell peppers, leeks, and plenty of Cheddar that toasts on top. It cuts into firm squares, which makes it as good cold in a lunchbox as it is hot from the oven.

Ingredients
• 2 tsp or 10 ml olive oil
• 1 medium leek, white and pale green parts, about 1 cup or 90g (3.17 oz), halved and sliced
• ½ cup or 75g (2.65 oz) diced red bell pepper
• ½ cup or 75g (2.65 oz) diced green bell pepper
• 1½ cups or 255g (9 oz) quinoa, rinsed and drained
• 2 cloves garlic, about 2 tsp or 6g (0.21 oz), minced
• 2 large eggs
• 1 cup or 240ml nonfat milk
• 1½ cups or 4 oz / 113g grated Cheddar cheese, plus more for sprinkling
Instructions
1. Sauté the aromatics: In a medium saucepan, warm the olive oil over medium heat. Add the sliced leek and diced bell peppers. Cover and cook for 5 minutes, until tender.
2. Toast the quinoa: Stir in the rinsed quinoa and minced garlic. Cook, uncovered, for 3-4 minutes, stirring frequently, until the quinoa is lightly toasted and fragrant.
3. Cook the quinoa: Pour in 3 cups (720 ml) of water and season with salt. Bring to a boil, then reduce heat to a simmer, cover, and cook for 15 minutes, or until the water is absorbed. Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork.
4. Prepare for baking: Preheat your oven to 350°F (175°C). Coat a 13×9-inch baking dish with cooking spray.
5. Mix the casserole: In a large bowl, whisk the eggs and milk. Fold in the cooked quinoa mixture and 1½ cups of grated Cheddar cheese until everything is evenly combined.
6. Bake to perfection: Transfer the mixture to the prepared baking dish. Sprinkle with additional cheese, if using. Bake for 30-35 minutes, until the edges are browned and the center is set. Let it rest for a few minutes before serving.

Pro Tips
• Don’t skip rinsing the quinoa! This crucial step removes its natural coating, called saponin, which can cause a bitter or soapy taste.
• Feel free to mix up the cheese. A blend of Monterey Jack and cheddar adds extra meltiness, while a pinch of Gruyère can add a sophisticated, nutty flavor.
• This casserole is perfect for meal prep. Assemble it completely (without baking), cover tightly, and refrigerate for up to 2 days. When ready to eat, bake as directed, adding 5-10 minutes to the cooking time.
FAQ
Q: Can I make this cheesy quinoa bake vegan
A: Yes, you can adapt this recipe to be fully vegan. Use a plant-based milk like unsweetened almond or soy milk. For the eggs, a vegan egg replacer or a flax egg (1 tbsp / 15 ml ground flaxseed mixed with 3 tbsp / 45 ml water per egg) works well as a binder. Finally, substitute the cheddar with your favorite dairy-free shredded cheese.
Q: How can I add more plant-based protein to this dish
A: To boost the protein content, consider adding one cup of rinsed and drained chickpeas or black beans when you fold in the quinoa mixture. You could also stir in some edamame or top the finished casserole with toasted nuts or seeds like pepitas for extra protein and crunch.
Q: What other vegetables work well in this quinoa casserole
A: This recipe is very versatile. Feel free to substitute the leeks and bell peppers with other vegetables like sautéed mushrooms, chopped broccoli florets, or wilted spinach. Just aim for about 2 cups (480 ml) of chopped vegetables in total to maintain the right ratio.
Q: Is this vegetarian casserole freezer-friendly
A: Absolutely. For best results, bake the casserole completely and let it cool to room temperature. You can freeze the entire dish or portion it into individual servings in freezer-safe containers for up to 3 months. Reheat in the oven or microwave until hot and bubbly.
