Quinoa & Spinach Casserole with Feta
Ingredients
- Main Casserole:
- 1 cup uncooked quinoa rinsed (or substitute brown rice for a heartier texture)
- 2 cups vegetable broth or chicken broth for added flavor
- 4 cups fresh spinach roughly chopped (or 2 cups frozen spinach, thawed and drained)
- 1 small onion finely diced
- 2 cloves garlic minced
- 1 cup crumbled feta cheese or goat cheese for a creamier tang
- ½ cup ricotta cheese optional, for extra creaminess
- 2 large eggs beaten (acts as a binder)
- 2 tbsp olive oil
- 1 tsp dried oregano or Italian seasoning
- Salt & pepper to taste
- Optional Topping:
- ½ cup shredded mozzarella or Parmesan
- ¼ cup breadcrumbs mixed with 1 tbsp olive oil for a golden crust
Instructions
- Cook quinoa: In a saucepan, combine quinoa and broth. Bring to a boil, then reduce to low, cover, and cook for 15 minutes until fluffy and liquid is absorbed. Set aside.
- Sauté aromatics: Heat olive oil in a skillet over medium heat. Add onion and garlic, cooking until fragrant and translucent (about 3–4 minutes). Stir in spinach and cook until wilted (2–3 minutes). Remove from heat.
- Mix filling: In a large bowl, combine cooked quinoa, sautéed spinach mixture, feta, ricotta (if using), oregano, eggs, salt, and pepper. Stir until well blended.
- Assemble casserole: Transfer mixture to a greased 9×9-inch baking dish. Smooth the top with a spatula. If using toppings, sprinkle mozzarella or Parmesan and breadcrumbs evenly on top.
- Bake: Preheat oven to 375°F (190°C). Bake uncovered for 25–30 minutes, until golden brown on top and set in the center.
- Rest & serve: Let sit for 5 minutes before slicing. The casserole should smell fragrant, with a lightly crisp golden crust and creamy interior.
