Step-by-Step Instructions

Prep & Cook Quinoa

Rinse the quinoa well. Then simmer it in broth or water until fluffy. Use leftover quinoa if you have it. This keeps the sweet potato quinoa bake fast and easy.

Roast Sweet Potatoes

Peel and cube the sweet potatoes. Toss with olive oil, salt, and pepper. Roast at 200°C / 400°F until tender and lightly golden. This adds sweet flavor and a creamy bite.

Mix Everything

Put quinoa, roasted sweet potatoes, onion, bell pepper, spinach, and corn in a bowl. Add cumin, paprika, garlic powder, salt, and pepper. Stir well so every bite tastes bold. You now have a hearty quinoa casserole base.

Bake & Melt

Spread the mix in a greased baking dish. Top with feta or shredded cheese, or use a dairy-free option. Bake until hot and the top looks golden. The casserole sets and the flavors blend.
