Aromatic bases & spice pastes
refogado
refogado · A slowly sweated aromatic base of onions cooked in fat until soft, translucent, and sweet — built upon with garlic, tomato, bay leaf, and optionally cilantro or palm oil. It is the invisible backbone of Portuguese, Brazilian, Angolan, Mozambican, Cape Verdean, and Goan savory cooking. Refogado is not fried; it is coaxed into sweetness through patience and controlled heat.
The formula
1:3–4 fat : onion (by weight)
Scale freely. 100 g fat + 300–400 g onion → ~500–600 g refogado. Brazilian/Goan: add 40–80 g tomato per 100 g onion. Portuguese with lemon zest: add zest at ~8–12 % of onion weight mid-cook. Cook down is ~30–35 % volume loss.
Identity
- Onions cooked in fat until translucent and honeyed, not browned or crispy
- Fat must be hot enough to shimmer and coat the onion, never smoking
- Salt added early to draw moisture and accelerate softening
- The mix is done when a spoon dragged through it leaves a trail for 3–4 seconds
- Regional variants build from this base with tomato, lemon zest, palm oil, or spices
Ingredients
| Base | Onion (yellow or white), diced to 5–8 mm | The foundation. Ratio: 3–4 parts per 1 part fat by weight. |
| Fat | Lard, butter, olive oil, or palm oil | Lard is classical for Portuguese/Angolan. Butter or oil for lighter applications. Palm oil (dendê) for Bahian and West African variants. |
| Aromatics | Garlic cloves, thinly sliced or minced | Added after onion has sweated 10–15 min — never burned. ~8–12 g per 1 kg onion. |
| Aromatics | Bay leaf (louro) | 1–2 dried leaves per 1 kg onion, added mid-cook. Removed before serving. |
| Acid | Tomato (seeded and grated or diced) | Added last in Portuguese refogado; integral in Brazilian, Goan, and West African versions. ~10–15 % of onion weight. |
| Seasoning | Fine sea salt | Added at the 5-minute mark of sweating to accelerate moisture release. 4–6 g per 1 kg onion. |
| Flavor | Lemon zest or cilantro stems (Brazilian / West African) | Brazilian refogado adds lemon zest mid-cook. West African adds cilantro stems and/or scotch bonnet. |
Method
- 1Choose and measure your fat.The fat ratio is the structural anchor. Too little fat and the onions steam; too much and they drown. Measure by weight for repeatability.
- 2Sweat the onion in fat over medium-low heat (120–140 °C), stirring occasionally.Low heat gently extracts water from the onion cells, softening pectin and developing natural sugars without browning prematurely. If the fat is smoking, the heat is too high.
- 3Add salt after the first 5 minutes of sweating.Salt disrupts onion cell walls (osmosis) and draws out liquid faster, accelerating pectin breakdown — the key to a soft, sweet base.
- 4Add garlic and bay leaf once the onion is translucent and beginning to collapse (15–20 minutes).Garlic burns quickly at these temperatures. Adding it now blooms its flavor into the fat without acrid bitterness.
- 5Cook until the onion is completely soft, jammy, and honeyed — a spoon dragged through it leaves a trail for 3–4 seconds.This is the structural signature of a proper refogado: fully sweated, not browned, not wet. The trail test confirms sufficient water evaporation and pectin gelatinization.
- 6Add tomato only in the final 5–8 minutes, if using.Tomato adds acidity and body. Too early and it breaks down to a watery paste; too late and it doesn't integrate. Brazilian and Goan versions often add it as a separate stage.
Techniques that matter
Sweating (transpiração)
Low-heat moisture extraction that softens pectin without caramelization — the defining texture of refogado.
Fat blooming
Garlic and bay leaf are fat-soluble; their aromatic compounds extract into the lipid medium, building layered flavor.
Pectin gelatinization
Onion cell walls contain pectin; as cells soften, pectin hydrates and gelatinizes, giving refogado its characteristic jammy, cohesive texture.
Osmosis (salt-accelerated)
Salt disrupts cell membrane integrity, speeding water release and the breakdown of structural polysaccharides.
Variations & derivatives
Refogado brasileiroBrazil (especially Minas Gerais and Bahia)
Onion and lemon zest (or lemon juice) are the core; garlic added late; tomato is common. Foundation for feijão, tutu de feijão, and moqueca.
Refogado angolano / moçambicanoAngola and Mozambique
Palm oil (dendê) replaces lard or is blended with it. Often includes scotch bonnet or piri-piri for heat. Foundation for moamba de galinha and calulu.
Refogado com tomatePortugal
Tomato is added as a finishing stage, especially in coastal regions. The canonical base for açordas, cataplanas, and many rice dishes.
Base de cebola goesaGoa, India (Indo-Portuguese cuisine)
Onion is cooked longer and darker (approaching light caramelization), with mustard seeds, curry leaves, and often coconut milk. Foundation for vindaloo, xacuti, and sorpotel.

Substitutions
- Yellow onion → White onion or shallot — Interchangeable by weight. Yellow preferred for higher sugar content and flavor depth.
- Lard → Olive oil or butter — Classic substitution for vegetarian or lighter applications. Flavor shifts notably; olive oil is closest in saturated/unsaturated balance.
- Fresh onion → Frozen, pre-diced onion — Diced and frozen onion has damaged cell walls and higher water content. Acceptable for weeknight cooking but produces a wetter, less refined base.changes result
Troubleshooting
Onions brown or burn during cooking
Heat is too high. Fat should shimmer gently, not smoke. Onions should steam in their own moisture, not fry. → Reduce heat to medium-low. If browning has begun, remove the vessel from heat, add a splash of water to halt the Maillard reaction, then continue on lower heat.
Refogado is watery or soupy
Insufficient cooking time or too-high heat forcing liquid out faster than it evaporates. Also: onion was cut too thick or tomato added too early. → Continue cooking over low heat, stirring frequently, until the mixture coalesces and the spoon-trace test passes. Do not rush this stage.
Garlic turns bitter and dark
Garlic added too early or heat too high. Allicin breakdown products become acrid when exposed to sustained high heat. → Add garlic only after onion is translucent. If it burns, discard and start over — the bitterness cannot be corrected.
Refogado is greasy or the fat separates
Too much fat relative to onion; or onion was not cooked long enough to incorporate the fat into the gelatinized pectin matrix. → If the fat hasn't been absorbed, continue cooking until the pectin fully hydrates and binds the lipid. Ensure the onion-to-fat ratio is correct (3–4:1).
