Follow these straightforward steps for an unforgettable Broccoli and Cheddar Quinoa Bake:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook Quinoa: In a medium pot, bring the vegetable broth or water to a boil. Add the rinsed quinoa, reduce the heat, cover, and simmer for 15 minutes. Once cooked, fluff with a fork.
3. Prepare Broccoli: While the quinoa cooks, steam the broccoli florets until they are tender but still vibrant, about 5 minutes.
4. Mix Wet Ingredients: In a large bowl, whisk together eggs, milk, garlic powder, onion powder, salt, pepper, and red pepper flakes if using.
5. Combine Ingredients: Add the cooked quinoa, steamed broccoli, sharp cheddar cheese, and Parmesan cheese to the egg mixture. Stir to combine thoroughly.
6. Prepare Baking Dish: Grease a baking dish with olive oil. A 9×9 inch dish works well for this recipe.
7. Transfer Mixture: Pour the quinoa and broccoli mixture into the prepared baking dish, spreading it evenly.
8. Add Breadcrumbs: Sprinkle the breadcrumbs over the top for a crunchy finish.
9. Bake: Place the dish in the oven and bake for 30-35 minutes, or until the top is golden brown and the edges are bubbly.
10. Cool Slightly: Remove from the oven and let it cool for about 5 minutes before serving.

These simple steps ensure that your Broccoli and Cheddar Quinoa Bake turns out perfectly every time!
