Cheesy Broccoli and Quinoa Casserole Recipe Walkthrough

First, set your oven to preheat at 375°F (190°C). While it warms up, lightly grease a 9x13 inch baking dish to prevent sticking later. Now, let’s cook the quinoa. Follow the package instructions to get it just right—fluffy but not mushy. Once done, set it aside and let it cool a bit.

Next up, melt butter in a medium saucepan over medium heat. Stir in the flour and whisk for about a minute. This forms the base of your sauce. Now, gradually add the milk, whisking constantly to avoid lumps. Sprinkle in the garlic powder, salt, and pepper. Keep whisking until the mixture thickens to a smooth, creamy consistency.

Once your sauce is thickened, remove it from heat and stir in the cheddar and Parmesan cheese until they're fully melted. This cheesy sauce is the heart of our casserole. In a large mixing bowl, combine the cooked quinoa, broccoli florets, and the cheese sauce. Mix until everything is evenly coated.

Pour the mixture into your prepared baking dish, spreading it out evenly. In a small bowl, mix the breadcrumbs with olive oil until they're well combined. Sprinkle this over the casserole for a crunchy topping.

Bake in the preheated oven for 25-30 minutes. You’re looking for a bubbly casserole with a golden-brown top. Once done, let it cool for a few minutes, then garnish with fresh parsley just before serving to add a fresh burst of flavor.
