3. Step-by-Step Instructions
Follow these instructions carefully, and you’ll get perfectly baked, flavorful onions every time.
Step 1 – Prepare the Onions
- Cut off the top and bottom of each onion.
- Slice halfway down the middle—but only to the center, not all the way through.
- Place them in a pot of simmering water.
- Boil for 10–15 minutes, until layers begin to loosen.
- Drain and cool.
- Carefully separate the layers of the onions, keeping them whole. Each layer will become a roll for filling.
🧠 Tip: Do not overboil the onions. They must be soft enough to separate but still strong enough to hold the filling.
Step 2 – Cook the Filling
- In a pan, heat 2 tbsp olive oil.
- Sauté shallot and garlic for 2 minutes.
- Add ground beef and sausage, breaking them apart.
- Once browned, add:
- salt
- pepper
- fennel seeds
- basil
- oregano
- thyme
- red pepper flakes (optional)
- tomato paste
- Stir in rice, canned tomatoes, and ½ cup broth.
- Cook until rice is slightly tender and most liquid is absorbed.
- Add parsley and remove from heat.
Step 3 – Prepare the Tomato Sauce
In a bowl, mix:
- Strained tomatoes (passata)
- 1 cup chicken broth
- Salt (if needed)
Taste and adjust seasoning.
Step 4 – Assemble
- Spread a thin layer of tomato sauce at the bottom of your baking dish.
- Place 2 tablespoons of filling inside each onion layer, then roll tightly.
- Place seam-side down.
- Continue until all onions are filled.
- Pour remaining sauce over the top.
Step 5 – Bake
- Cover with foil.
- Bake at 425°F (220°C) for 30–35 minutes.
- Remove foil and bake for another 20–30 minutes.
- For a golden finish, broil for 2 minutes.
Step 6 – Finish & Serve
Let rest for 10 minutes before serving.
Drizzle with:
- Balsamic glaze
- Olive oil
- Chopped parsley
Serve warm and enjoy!
4. Pro Tips for Success
Here are expert tips to ensure this recipe turns out perfectly every time:
💡 Minimize Tears When Cutting Onions
- Chill the onions before slicing.
- Use a sharp knife.
- Slice near open ventilation if possible.
💡 Don’t Fully Cook the Rice
The rice must finish cooking inside the onion, so it absorbs flavors from the sauce and meat.
💡 Use a Deep Baking Dish
Tomato sauce should reach at least halfway up the rolls to keep them moist.
💡 Let It Rest Before Serving
Resting helps flavors blend and makes slicing easier.
