Ingredients
For the Stuffed Onions:
4 large yellow onions
1½ pounds ground beef (80/20 or lean beef)
1 tablespoon olive oil
3 cloves garlic, minced
1 small onion, finely chopped (from the removed onion centers)
1 tablespoon tomato paste
1 teaspoon smoked paprika
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning
½ teaspoon salt
½ teaspoon black pepper
¼ teaspoon chili flakes (optional)
2 tablespoons fresh parsley, chopped
For the Cheese Topping:
1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
¼ cup Parmesan cheese
Optional Additions:
½ cup cooked rice
½ cup mushrooms, finely chopped
½ cup spinach
2 tablespoons Worcestershire sauce
Fresh herbs for garnish
Instructions
Step 1: Prepare the Onions

Preheat oven to 375°F (190°C).

Peel the outer layer of the onions.

Cut a small slice from the top and bottom of each onion to help them stand upright.

Carefully remove the inside layers of each onion, leaving about 2–3 outer layers intact to create a sturdy shell.

Chop the removed onion pieces and save them for the filling.

Step 2: Prepare the Beef Filling

Heat olive oil in a large skillet over medium heat.

Add chopped onion centres and cook for 3–4 minutes until softened.

Add minced garlic and cook for 30 seconds until fragrant.

Add ground beef and cook until browned, breaking it apart with a spoon.

Drain excess fat if needed.

Step 3: Season the Filling

Add:

Tomato paste
Smoked paprika
Garlic powder
Onion powder
Italian seasoning
Salt
Black pepper
Chili flakes

Mix well and cook for another 2–3 minutes.

Remove from heat and stir in fresh parsley.

Allow filling to cool slightly.

Step 4: Fill the Onion Shells

Place hollowed onions in a baking dish.

Carefully spoon the seasoned beef mixture into each onion shell.

Press gently to fill completely.

Do not overpack too tightly because the filling needs space to cook evenly.

Step 5: Add Cheese

Top each stuffed onion generously with:

Cheddar cheese
Mozzarella cheese
Parmesan cheese

The cheese will melt into a golden, delicious topping.

Step 6: Bake

Cover the baking dish loosely with foil.

Bake for 35 minutes.

Remove foil and bake another 10 minutes until the cheese is melted, bubbly, and golden.

For extra browning, broil for 1–2 minutes while watching carefully.

Step 7: Serve

Allow stuffed onions to cool for a few minutes.

Garnish with fresh parsley and extra Parmesan.

Serve warm with:

Green salad
Roasted vegetables
Cauliflower mash
Garlic bread
Tips & Notes
1. Choose Large Onions

Large yellow or sweet onions work best because they create a bigger shell for stuffing.

2. Be Gentle While Hollowing

Remove onion layers carefully to avoid breaking the outer shell.

3. Precook the Beef

Always cook the ground beef before stuffing to ensure even cooking and better flavour.

4. Add Moisture for Juiciness

Tomato paste, Worcestershire sauce, or a splash of broth helps keep the filling moist.

5. Use Different Cheese

Try:

Pepper jack for spice
Gruyère for richness
Monterey Jack for extra meltiness
6. Make Ahead Option

Prepare stuffed onions up to 24 hours ahead and store covered in the refrigerator before baking.

7. Storage

Store leftovers in an airtight container for up to 4 days.

Reheat in the oven or air fryer for the best texture.

Recipe Notes

Do not make onion shells too thin because they may collapse.
For extra flavour, add fresh herbs before serving.
If onions release too much liquid during baking, drain carefully before serving.
Add cooked rice or quinoa if you prefer a more traditional stuffed vegetable style.
Use freshly grated cheese for the smoothest melt.
Let the stuffed onions rest for 5 minutes before serving so the filling sets.
