Creating amazing Greek Stuffed Onions can be simple with the following steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Onions: Peel the onions and slice off the tops. Carefully hollow out the insides, leaving a thin layer intact. Reserve about 1 cup of the onion flesh for the stuffing.
3. Cook Rice: In a saucepan, combine rice and water (or broth). Bring to a boil, then reduce heat and simmer until fully cooked, about 15 minutes. Remove from heat and let cool.
4. Sauté Onion Flesh: In a skillet, heat olive oil over medium heat. Add the reserved onion flesh and sauté until translucent.
5. Combine Ingredients: In a large mixing bowl, combine sautéed onion, cooked rice, salt, pepper, oregano, parsley, cinnamon, and pine nuts (if using). Mix well.
6. Stuff Onions: Fill the hollowed onions with the rice mixture, packing it tightly.
7. Place in Baking Dish: Arrange the stuffed onions in a baking dish and drizzle with olive oil and lemon juice.
8. Cover and Bake: Cover the dish with aluminum foil and bake for 45 minutes. Remove foil and bake for an additional 15 minutes until the tops are golden.
9. Add Feta Cheese: If using, sprinkle crumbled feta over the onions for the last 5 minutes of baking.
10. Cool Before Serving: Once done, let the onions cool slightly before serving.

By following these steps, you’ll create a flavorful dish that truly embodies the charm of Greek cooking.
