How to Make Greek Stuffed Onions

Prepare Onions: Boil a pot of salted water. Cut the ends of the sweet yellow onions and score the sides. Boil the onions for 10-12 minutes until slightly soft, then drain and cool. Carefully separate the layers for stuffing.
Make the Filling: In a skillet, sauté finely chopped onion and garlic in olive oil until translucent. Add the ground beef or lamb, cooking until browned. Mix in long-grain rice, fresh herbs, and spices; allow this delicious filling to cool.
Stuff Onions: Take each onion layer and fill it with the savory mixture, packing it gently to maximize flavor. Place the stuffed onions seam-side down in a greased casserole dish for a secure hold.
Prepare Sauce: In the same skillet, heat a little olive oil and sauté more garlic. Add crushed tomatoes, broth, lemon juice, and herbs. Let this simmer for 5-7 minutes, developing rich flavors to complement the onions.
Bake: Pour the sauce over the stuffed onions. Cover the casserole with foil and bake at 375°F (190°C) for 45 minutes. Remove the foil and bake for an additional 20-30 minutes until golden and bubbling. Allow them to rest before serving, and enjoy the delightful aroma!

Optional: Serve with a sprinkle of fresh parsley for an added touch of color.

Expert Tips for Greek Stuffed Onions

Choose the Right Onions: Sweet yellow onions are ideal due to their mild flavor, enhancing the overall taste of your Greek Stuffed Onions.
Don’t Overcook: Boil onions just until tender. Overcooking can lead to breakage when stuffing, ruining your dish’s presentation.
Flavor Boost: For a richer filling, allow your sautéed onions and garlic to cool before mixing in spices and meats; this creates a harmonious blend of flavors.
Versatile Filling: Feel free to experiment with different proteins or grains. Ground lamb adds authenticity, while quinoa offers a hearty vegetarian option.
Simmering Time: Ensure your sauce simmers long enough to infuse flavors; a quick simmer won’t develop the rich depth you want for your Greek Stuffed Onions.
