In this article
Discover Cebollas Rellenas, Argentina’s wonderfully unfussy take on the stuffed onion! Sweet, mellow onions are hollowed out, packed with a savoury, paprika-spiked filling and baked until the edges catch and caramelise. It is the kind of dish that looks far more elaborate than it is, and because it can be assembled hours ahead, it slips neatly onto the table whether you are feeding the family or entertaining friends.
About Cebollas Rellenas
Cebollas rellenas are a delicious and hearty dish, long popular in Spanish and Argentine kitchens alike. The recipe plays the natural sweetness of baked onions against a well-seasoned filling that can be varied to suit whatever you fancy. It works beautifully as a starter or as a main course, and wins people over with its straightforward preparation and full, rounded flavour. Better still, you can put it together in advance and simply slide it into the oven when your guests arrive — which makes it a genuinely stress-free choice for dinner parties.
Ingredients (serves 1–2)
- 2 large onions
- 150 g minced beef (or a beef and pork mix)
- 1 small tomato
- 1 garlic clove
- 1 tsp paprika
- Salt and pepper to taste
- 150 g cheese, grated (optional)
- Olive oil
Shopping for the ingredients
When shopping for cebollas rellenas, it pays to pick out fresh, good-quality ingredients. Look for onions that feel firm in the hand and are free of soft spots or blemishes. For the filling you can go with minced beef or a vegetarian alternative, depending on your preference. Everything else — tomatoes, garlic and the spices — is available in any supermarket, and choosing the freshest you can find will give you the best flavour in the finished dish.
Preparing the dish
Preparing this dish is simple enough, though it does ask for a little time. Start by peeling the onions and slicing a lid off the top of each one. Hollowing out the onions is the key step here, since it creates the space for the filling. As you scoop out the centres, chop them and set them aside — they go straight into the filling, adding depth and a touch more sweetness. This is much the same prep logic behind Paltas Rellenas, where the vessel itself becomes part of the meal.
Step-by-step instructions
- Prepare the onions and scoop out the centres.
- Fry the minced beef in a pan with the finely diced tomato and the garlic.
- Add the chopped onion centres to the pan and mix everything together well.
- Season with paprika, salt and pepper.
- Spoon the mixture into the onion shells and, if you like, scatter over the grated cheese.
- Sit the stuffed onions in an ovenproof dish, drizzle with olive oil and bake at 180 °C for around 30 minutes.
Gluten-free / lactose-free version
Cebollas rellenas are naturally a gluten-free and lactose-free dish. Just check that your minced beef contains no gluten-based fillers, or choose an alternative filling, if you need to keep things strictly gluten-free. To avoid lactose, use a lactose-free cheese or simply leave the cheese out altogether — the dish loses nothing essential. That way anyone with an intolerance can tuck in without a second thought.
Tips for vegans and vegetarians
There are plenty of ways to adapt cebollas rellenas for vegans and vegetarians. In place of the mince, try a mixture of quinoa, beans or tofu. Vegetables such as courgette or peppers also make a lovely addition to the filling, in the spirit of a Tarta de Zapallitos. With the right spices and herbs, the dish stays every bit as aromatic and satisfying.
More tips and tricks
A few extra touches can lift both the flavour and the look of your cebollas rellenas. Experiment with spices such as cumin or Italian herbs to add a signature note of your own. Fresh herbs like parsley or coriander make an excellent garnish, and it is worth being playful with the plating: an appetising presentation makes the dish that much more inviting.
Adapting the recipe to your taste
One of the real advantages of cebollas rellenas is how easily the recipe bends to personal preference. You can build the filling exactly as you like it and try out different ingredients each time. Add hot chilli peppers for a spicier edge, or reach for different cheeses to shift the flavour in another direction entirely. It is an easy way to make sure everyone at the table gets something they love.
Ingredient substitutions
There are many alternatives you can call on to tailor this recipe. Instead of minced beef, lentils or chickpeas make an excellent source of protein — the same pulses that carry a good Garbanzos a la Riojana. And if you fancy a change from onions, large peppers can be stuffed in much the same way for a closely related dish. Be creative and try different combinations until you land on your perfect filling.
Drink pairing ideas
The right drink rounds off the whole experience. Cebollas rellenas go nicely with a light white wine or a crisp rosé. For alcohol-free options, ice-cold soft drinks or freshly pressed juices are a good match, and a cup of Mate Cocido makes a fittingly Argentine finish to the meal. Keep the flavours of the filling in mind when you choose, and you will end up with a harmonious menu.
Serving and presentation ideas
Thoughtful presentation is what makes cebollas rellenas really appealing on the table. Set against a white plate, the colours of the filling stand out beautifully. Garnish with fresh herbs and a slice of lemon for an extra flash of colour. A simple Ensalada Criolla alongside adds freshness and turns the plate into a complete meal, so your dish is not just delicious but a pleasure to look at.
A bit of history
Cebollas rellenas have a long culinary tradition and are popular across many countries. Similar dishes turn up throughout Spain, often made with whatever regional ingredients are close to hand. The filling changes from region to region and cook to cook, which is exactly what has kept the dish so versatile. Historically it was made as a family dish, ideal for large gatherings and celebrations — a spirit it shares with much of Argentine cuisine.
