Step‑by‑Step Instructions for Stuffed Onions
Step 1: Preheat the Oven
Start by preheating your oven to 425°F (220°C). This step is crucial as it ensures a perfectly cooked exterior for your stuffed onions. While the oven heats up, gather your baking dish and prepare your workspace, allowing everything you need to be within reach.
Step 2: Prepare the Onions
Bring a large pot of water to a boil. While waiting for the water to boil, trim the tops and bottoms of the large yellow onions before making four evenly spaced incisions along the sides. This will make peeling them easier once they’re cooked.
Step 3: Soften the Onions
Carefully drop the prepared onions into the boiling water. Allow them to simmer for about 10–15 minutes until they are tender but not fully cooked, as they’ll continue to soften in the oven. Look for a slight translucency, which indicates they are ready to be removed.
Step 4: Cool the Onions
Once softened, transfer the onions to a colander and let them cool for a few minutes. This step is essential as it allows for manageable handling when you begin to carefully scoop out the insides.
Step 5: Sauté Aromatics
In a large frying pan over medium heat, add a tablespoon of olive oil. Once it shimmers, add minced garlic and finely chopped shallots. Sauté these aromatics until they’re fragrant and just golden, about 3-4 minutes. This step enhances the flavor profile of your stuffed onions.
Step 6: Brown the Meat
Next, incorporate the lean ground beef and ground Italian sausage into the pan. Cook the meat mixture for approximately 7–10 minutes, breaking it apart with a wooden spoon until it’s browned and fully cooked. You want it to be no longer pink, indicating it’s ready for seasoning.
Step 7: Season the Filling
Once the meat is browned, add salt, black pepper, crushed fennel seeds, dried basil, oregano, and red pepper flakes (if using). Stir well to ensure the spices distribute evenly for a robust flavor in your stuffed onions. Continue cooking for an additional 2-3 minutes until fragrant.
Step 8: Add Rice and Tomatoes
Incorporate the jasmine rice, finely chopped tomatoes, and chicken broth into the pan. Cook the mixture for about 10 minutes, stirring occasionally, until the liquid is mostly absorbed, and the rice is tender. This mixture will be the savory filling for your stuffed onions.
Step 9: Mix in Fresh Herbs
Remove the pan from heat and gently fold in the fresh parsley and thyme into the filling. This step adds a burst of freshness to your stuffing, which will elevate the flavor of your stuffed onions.
Step 10: Prepare the Sauce
In a separate bowl, combine strained tomatoes, additional chicken broth, salt, and pepper to create your sauce. This blend will enrich the bottom of your baking dish and keep the stuffed onions moist during baking, ensuring a delightful texture and flavor.
Step 11: Assemble the Dish
Place a layer of sauce at the bottom of your baking dish. Carefully scoop out the cooled onions, removing the inner layers, and fill each layer with the flavorful meat mixture. Arrange the stuffed onions seam-side down in the prepared dish, ensuring they are secure and snug.
Step 12: Bake and Finish
Cover the dish with foil and bake for 30–35 minutes. After this time, remove the foil and bake for an additional 20–30 minutes until the onions are golden on top and the sauce is bubbling. Let the stuffed onions rest for about 10 minutes, then drizzle with balsamic glaze and garnish with parsley to serve.

Stuffed Onions Recipe FAQs
What type of onions are best for stuffing?
For the best results, I recommend using large yellow onions as they offer a sweet flavor and are easier to stuff. The larger size allows for ample filling, creating a delicious balance between the onion and the savory meat mixture. If you can’t find yellow onions, sweet onions also work well!
How should I store leftover stuffed onions?
Store your cooked stuffed onions in an airtight container in the fridge for up to 4 days. When you’re ready to enjoy them again, simply reheat in a covered dish at 350°F (175°C) to ensure they retain their moisture and flavor, making every bite just as delightful as when they were freshly baked.
Can I freeze stuffed onions?
Absolutely! To freeze assembled but uncooked stuffed onions, place them in a freezer-safe container or wrap them tightly in foil, and they can last for up to 3 months. When you’re ready to cook them, just thaw in the fridge overnight and bake as per the recipe instructions.
What if my filling is too dry or too wet?
If your filling appears too dry, add a splash more chicken broth or a drizzle of olive oil to moisten it. On the other hand, if it’s too wet, you can incorporate a bit more rice or breadcrumbs to absorb excess moisture. Just mix until you reach your desired consistency for the filling.
Are stuffed onions suitable for a vegetarian diet?
Yes! You can easily make a vegetarian version by replacing the meat with cooked lentils, quinoa, or a variety of finely chopped vegetables combined with spices. This not only gives you a hearty filling but also keeps the delight of stuffed onions intact.
Can I make stuffed onions ahead of time?
Definitely! You can assemble the stuffed onions a day in advance and store them in the refrigerator until you’re ready to bake. This allows the flavors to meld beautifully, adding extra depth to the dish when you finally serve them!
