Zapallo al Horno, Argentine Roasted Pumpkin, Roast Zapallo

This argentine roast pumpkin recipe cuts zapallo into thick wedges, coats them in olive oil with onion, garlic, oregano and sweet paprika, and roasts them at 200°C (400°F) until the edges caramelise and the flesh turns soft and sweet. It is the classic asado side: simple, golden and made to be eaten with grilled meat and chimichurri. One serving is about 306 g.

Zapallo, the squash family pumpkin of the Andes and the River Plate, has been grown in South America since long before European arrival, and roast wedges of it are a fixture of the Argentine asado — the long, slow barbecue where meat cooks over coals and simple vegetable sides like pumpkin, onion and potato roast alongside. The seasoning stays simple: oil, salt, oregano and paprika, with chimichurri on the table.

Pairs well with: Grilled beef or chorizo from the asado, with chimichurri on the side

Measured Ingredients

Pumpkin (zapallo) 1200g (2 1/2 lb) peeled flesh

About 1.6 kg whole before peeling and seeding. Substitute: Butternut squash or kabocha, same weight of flesh.

How to choose: Heavy for its size, with firm skin and no soft spots; a sugar pumpkin or kabocha holds its shape best.

How to prepare: Halve, scoop out the seeds and strings, peel, and cut into wedges about 3 cm thick.

Required
White onion 150g (5.3 oz)

About 2 small onions, cut into wedges. Substitute: Red onion, same weight.

How to choose: Firm and heavy, with dry papery skin.

How to prepare: Halve and cut into wedges about 2 cm wide, keeping the root end intact so the layers stay together.

Garlic 30g (1 small head)

About 8 cloves, left whole and unpeeled. Substitute: 2 teaspoons garlic powder, tossed with the oil.

How to choose: Plump, firm cloves with no green sprout.

How to prepare: Break the head into cloves and leave them unpeeled — they roast soft and sweet in their skins.

Extra virgin olive oil 45ml (3 tablespoons)

To coat the wedges. Substitute: Another mild vegetable oil, same amount.

How to choose: A fresh, grassy-smelling oil.

How to prepare: Measure out 3 tablespoons.

Required
Fine sea salt 5g (1 teaspoon)

For seasoning the wedges. Substitute: Kosher salt, same weight.

How to choose: Fine salt sticks to the oiled wedges evenly.

How to prepare: Measure out 1 teaspoon.

Required
Black pepper 2g (1/2 teaspoon)

Freshly ground. Substitute: White pepper, same amount.

How to choose: Whole peppercorns, ground fresh for the best flavour.

How to prepare: Grind 1/2 teaspoon.

Required
Dried oregano 3g (1 tablespoon)

Argentine-style, rubbed between the palms. Substitute: Dried thyme, same amount.

How to choose: Fragrant, grey-green leaves that crumble easily.

How to prepare: Rub between your palms over the wedges to wake up the oils.

Required
Sweet paprika 4g (2 teaspoons)

For colour and gentle warmth. Substitute: Smoked paprika, same amount, for a deeper flavour.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 55m

Prep Stage: Pumpkin, Onion and Seasoning

15 Mins • Pumpkin, Onion and Seasoning

Heat the oven to 200°C (400°F) and line a large rimmed baking tray with baking paper. Halve the pumpkin, scoop out the seeds and strings, peel it and cut the flesh into wedges about 3 cm thick. Cut the onions into wedges and break the garlic into unpeeled cloves, then toss everything on the tray with the olive oil, salt, pepper, oregano and paprika.

Maestro Tip: Cut the wedges evenly — thin pieces burn while thick ones are still raw, so aim for the same thickness all round.

1
Heat the oven and line the tray

5 Mins 200°C (400°F)

Heat the oven to 200°C (400°F) with a rack in the middle. Line a large rimmed baking tray with baking paper so the caramelised edges do not stick.

A hot oven from the start is what browns the pumpkin instead of steaming it.

Done when: Oven at 200°C (400°F); tray lined and ready.
2
Cut and season the wedges

10 Mins No heat — chopping board

Halve the pumpkin, scoop out the seeds and strings with a spoon, and peel it. Cut the 1,200 g of flesh into wedges about 3 cm thick and spread them on the tray in a single layer with the 150 g of onion wedges and the 30 g of garlic cloves. Drizzle over the 45 ml of olive oil, sprinkle the 5 g of salt, the pepper, the 3 g of oregano and the 4 g of paprika, and toss with your hands until every piece is coated.

Do not crowd the tray — wedges that touch steam instead of roasting, so use two trays if you need to.

Done when: Wedges in a single layer, evenly coated with oil and spices.
3
Roast until golden

25 Mins 200°C (400°F)

Put the tray in the oven and roast for 25 minutes, until the undersides are golden and the edges are starting to caramelise. Turn each wedge once with tongs so the other side can brown.

Turn gently — the flesh is softening by now and rough handling breaks the wedges apart.

Done when: Undersides golden brown; flesh yielding to a knife.
4
Finish, rest and serve

15 Mins 200°C (400°F), then rest

Roast for 15 minutes more until the wedges are deeply golden at the edges and a knife slides through the thickest part with no resistance. Take the tray out, rest the pumpkin for 5 minutes, then slide the wedges onto a warm platter with the roasted onion and garlic.

The 5-minute rest lets the caramelised edges firm up so the wedges hold together on the plate.

Done when: Wedges deeply golden, soft right through, holding their shape.

Finishing Touches & Plating

Serve warm from the platter, with the soft roasted garlic squeezed over the top and chimichurri on the side for the meat.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Pumpkin is rich in vitamin A (beta-carotene) and vitamin C, onion and garlic add vitamin C and vitamin B6, and the dish supplies potassium. All nutrition values are estimated.

Vitamin A From Real Pumpkin

Each serving carries about 300 g of pumpkin, so the plate is rich in beta-carotene, which the body turns into vitamin A.

Naturally Sweet, Nothing Added

The sweetness is the pumpkin itself, caramelised in the oven — there is no added sugar in this dish at all.

Light Side, Big Flavour

At 209 calories a serving with 3.1 g of fibre, it fills the plate next to grilled meat without filling you up before the main event.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Sides

Chimichurri

Sharp parsley, garlic and vinegar chimichurri cuts the sweetness of the roast pumpkin and is the classic Argentine table sauce.

Grilled Beef or Chorizo

The pumpkin was made for the asado — its soft sweetness balances smoky, salty grilled meat better than any starchy side.

Vegetables

Ensalada Criolla

Crisp tomato, onion and pepper salad adds a fresh, acidic crunch that keeps the plate from feeling too soft and sweet.

Drinks

Red Wine or Sparkling Water

A glass of Malbec suits the asado table, and plain sparkling water with lemon does the same refreshing job without alcohol.

Full Menus

Full Asado Menu

Serve the pumpkin with grilled beef, chorizo, ensalada criolla and chimichurri, and finish with fresh fruit — the pumpkin is the sweet, golden side of the feast.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

A Second Sweet Side on the Plate

Sweet potato or glazed carrots beside roast pumpkin double the sweetness and leave the plate with nothing savoury to balance it — pick one sweet side. This is general nutrition information, not medical advice.

Crowding the Tray

Wedges packed tight steam in their own moisture, turn soggy and never caramelise; the single layer and the hot oven exist to keep them golden and firm. This is general food information, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

General adultsA warm, golden side for a lunch of grilled meat — one serving with beef and salad is a full plate.
ChildrenSoft, sweet and easy to eat; cut the wedges into small pieces and let them cool a little before serving.
ElderlySoft all the way through and easy to chew; serve the wedges well cut up with the soft roasted garlic.
Pregnant womenFine as written — no raw meat or unpasteurised cheese; eat it hot and freshly roasted.
Breastfeeding womenA nourishing, vegetable-rich side; the olive oil adds healthy fats and the pumpkin is gentle on digestion.
AthletesAbout 26 g of carbohydrate per serving makes it a useful recovery side after training, paired with grilled meat.
Weight gainServe two helpings with extra grilled meat to raise the energy of the meal.
Weight lossOne serving with grilled chicken and salad keeps the plate light while keeping the same sweet, roasted flavour.

Health Conditions — Adjust or Avoid

Conditions

DiabetesAbout 26.2 g of carbohydrate per serving, mostly from the pumpkin itself — a moderate load; ask a clinician about portion size.
High blood pressureAbout 497 mg of sodium per serving; the salt is measured and there is no added stock or sauce, and ask a clinician.
Kidney diseasePumpkin is moderate in potassium and the protein is low; keep the portion moderate and ask a clinician about what fits your plan.
GoutPumpkin, onion and olive oil are not usual gout triggers; keep the portion moderate and ask a clinician.
Stomach issuesSoft, well-cooked pumpkin is usually gentle on the stomach; eat a small portion if onion bothers you, and ask a clinician if symptoms flare.
Cardiovascular diseaseOlive oil and vegetables with no frying fit a heart-friendly pattern; keep the oil measured, and ask a clinician.
Fatty liverRoasted vegetables and olive oil with no added sugar fit a liver-friendly plate; keep the portion moderate and ask a clinician about fat intake.
Food allergiesContains no gluten, dairy, egg, nuts or seafood as written. Ask a clinician about any allergy.
Special therapeutic dietsA soft, easy-to-chew side that suits many therapeutic diets; ask a clinician or dietitian before changing your diet.

If you have a medical condition, consult your doctor before changing your diet.

Storage & Use

How to store: Cool within 2 hours, then store the wedges in a sealed container.
In the fridge: 4 days in the fridge at 4°C (39°F) or below.
In the freezer: Up to 3 months; the wedges soften further after freezing, so freeze them flat in a single layer.
How to reheat: Reheat on a tray in the oven at 180°C (350°F) for 10 to 12 minutes until hot right through, about 74°C (165°F); the microwave works but softens the edges.
Freezing recommended: Yes — roast pumpkin freezes well for up to 3 months.
Signs it has spoiled: Sour or off smell, slimy wedges, or mould on the surface — discard them.

Chimichurri steak is the centrepiece of the Argentine asado: a thick sirloin grilled over high heat until charred outside and juicy inside, rested, sliced, and served with chimichurri — the raw sauce of parsley, garlic, oregano, red wine vinegar and olive oil that Argentina puts on almost everything grilled. The sauce is made first so its flavours can meld while the steak cooks. One serving is about 215 g.

Milanesa a la Napolitana

Milanesa a la napolitana starts as a milanesa — a thin beef steak pounded flat, dredged in flour and egg, coated in breadcrumbs and fried until crisp — and then becomes something else entirely: topped with tomato sauce, a slice of ham and a blanket of mozzarella, it goes back into the oven until the cheese bubbles. It is the dish Argentine families order at the neighbourhood bodegon, always with French fries. One serving is about 350 g, before the fries.

Comforting & Satisfying

A crisp breaded steak, fried golden, then finished in the oven under tomato sauce, ham and bubbling mozzarella — Argentina's favourite comfort plate.
