How to Make Baked Beef & Rice Stuffed Onions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a large baking dish.
A 9×13-inch dish works well for most batches.
2. Prepare the Onions
Peel away the dry outer skins from the onions.
Trim only a small amount from the root and stem ends.
Try to leave enough of the onion intact so the layers remain easy to separate.
3. Bring Water to a Boil
Fill a large pot with enough water to cover the onions.
Add approximately 1 teaspoon salt.
Bring to a gentle boil.
4. Boil the Onions
Carefully place the whole onions into the water.
Cook for approximately 10–15 minutes.
The outer layers should soften enough to bend without tearing.
5. Cool Slightly
Remove the onions with a slotted spoon.
Transfer them to a plate or bowl.
Let them cool until they are comfortable to handle.
6. Separate the Onion Layers
Carefully make one vertical cut from the outside toward the center of each onion.
Do not slice completely through both sides.
Gently peel away the softened onion layers one at a time.
The larger outer layers will be easiest to stuff.
7. Save the Smaller Onion Pieces
Finely chop the small center pieces that are too narrow to fill.
You will add some of them to the beef mixture.
This reduces waste and adds more onion flavor.
8. Prepare the Rice
If you have not already cooked the rice, prepare it according to package directions.
Allow it to cool slightly before mixing with the beef.
Cooked rice is preferred because it gives you better control over the final texture and liquid level inside the casserole.
9. Prepare the Beef
Place the ground beef in a large mixing bowl.
10. Add the Rice
Add the cooked rice.
11. Add the Chopped Onion
Add approximately ½ cup finely chopped onion centers.
12. Add the Garlic
Stir in the minced garlic.
13. Add the Egg
Add one large egg.
The egg helps the filling hold together as the onions bake.
14. Add Tomato Paste
Add 2 tablespoons tomato paste.
15. Add Worcestershire Sauce
Pour in the Worcestershire sauce.
16. Add the Herbs and Seasonings
Add:
- Parsley
- Smoked paprika
- Garlic powder
- Onion powder
- Oregano
- Thyme
- Salt
- Black pepper
- Red pepper flakes, if using
17. Add Optional Cheese
If you want a richer filling, add ½ cup shredded mozzarella or cheddar.
18. Mix Gently
Using clean hands or a large spoon, mix until everything is evenly combined.
Do not overwork the ground beef.
Overmixing can make the filling dense.
19. Prepare the Sauce
In a medium bowl, combine:
- Crushed tomatoes or tomato sauce
- Beef broth
- Tomato paste
- Worcestershire sauce
- Brown sugar or honey
- Garlic
- Italian seasoning
- Smoked paprika
- Salt
- Black pepper
Whisk until smooth.
20. Add Sauce to the Baking Dish
Pour approximately 1 cup of sauce into the bottom of the prepared baking dish.
Spread it evenly.
21. Fill an Onion Layer
Lay one softened onion layer on a clean work surface.
Place approximately 2 tablespoons filling near one end.
The exact amount depends on the size of the onion layer.
22. Roll the Onion
Fold or roll the onion layer around the filling.
It does not need to be perfectly sealed.
The onion naturally curls around the beef mixture.
23. Place Seam-Side Down
Arrange the stuffed onion seam-side down in the baking dish.
24. Continue Filling
Repeat until all usable onion layers have been filled.
Arrange them fairly close together so they help support one another while baking.
25. Use Remaining Filling
If you have extra beef filling, shape it into small meatballs and place them between the stuffed onions.
26. Pour Over the Sauce
Pour the remaining tomato sauce evenly over the stuffed onions.
Try to coat most of the exposed surfaces.
27. Cover Tightly
Cover the baking dish tightly with foil.
28. Bake Covered
Bake for approximately 45 minutes.
The steam trapped beneath the foil helps soften the onions and cook the filling evenly.
29. Check the Beef
Carefully uncover one stuffed onion and check the center.
Ground beef should reach 160°F (71°C).
30. Continue Baking if Needed
If necessary, cover again and bake for another 10–15 minutes.
The onions should be very tender.
31. Add Cheese
If using the cheese topping, sprinkle mozzarella and Parmesan over the stuffed onions.
32. Bake Uncovered
Return the dish to the oven uncovered.
Bake for approximately 10–15 minutes.
The sauce should bubble gently and the cheese should melt.
33. Broil for Extra Browning
For a golden finish, broil for approximately 1–2 minutes.
Watch carefully.
34. Rest
Remove the stuffed onions from the oven.
Let them rest for approximately 10 minutes.
This allows the filling to settle and makes them easier to serve.
35. Garnish
Finish with:
- Fresh parsley
- Basil
- Parmesan
- Black pepper
36. Serve
Spoon some of the tomato sauce from the bottom of the dish over each stuffed onion.
Serve hot.

Tips for the Best Beef & Rice Stuffed Onions
Choose Large Onions
Large yellow or sweet onions provide wider layers that are much easier to stuff.
Don’t Overcook During Boiling
The onions should become flexible but not fall apart.
Separate Carefully
If a layer tears slightly, it can usually still be wrapped around the filling.
Use Cooked Rice
Pre-cooked rice prevents the filling from absorbing too much sauce and becoming dry.
Keep the Filling Moist
Ground beef, rice, egg, tomato paste, and sauce should create a filling that holds together without feeling dry.
Don’t Pack Too Tightly
The beef needs a little space to cook evenly.
Bake Covered First
This is important for producing soft, tender onion layers.
Use a Thermometer
Ground beef should reach 160°F in the center.
Rest Before Serving
The filling firms slightly as it rests, making the stuffed onions easier to handle.

Frequently Asked Questions
What onions work best for stuffed onions?
Large yellow or sweet onions are ideal because they have wide layers and become tender and mildly sweet when baked.
Do I need to cook the beef first?
No. The beef can go into the onion layers raw as long as the stuffed onions are baked until the filling reaches 160°F.
Can I use uncooked rice?
Cooked rice is recommended. Raw rice would require significantly more liquid and could make the filling cook unevenly.
Why are my onion layers tearing?
The onions may not have softened enough during boiling. Give them a few more minutes until flexible.
Can I make these ahead?
Yes. Assemble them up to a day ahead, cover, and refrigerate until ready to bake.
Can I use ground turkey or chicken?
Yes. Cook poultry fillings to 165°F.
Can I add cheese?
Absolutely. Mozzarella, cheddar, Parmesan, or feta all work well.
How do I know when the onions are done?
The onion layers should be very tender and easily cut with a fork, while the beef filling should reach 160°F.
Final Thoughts
These Baked Beef & Rice Stuffed Onions combine tender sweet onion layers, savory ground beef, fluffy rice, garlic, herbs, tomato sauce, and optional melted cheese in one comforting baked meal.
The key is softening the onions enough to separate their layers without overcooking them, using cooked rice in the filling, and baking everything covered until the onions become tender and the beef reaches 160°F.
Serve them with extra tomato sauce, fresh parsley, and a simple salad or mashed potatoes for a hearty family dinner that is comforting, flavorful, and a little different from traditional stuffed vegetables.
