Method
Trim and cut the eggplant, zucchini, red bell pepper, and green bell pepper into uniform 1 cm (0.4 inch) dice on the cutting board using the chef's knife.
Finely dice the yellow onions and finely mince the peeled garlic cloves on the cutting board using the chef's knife.
Core and finely dice the ripe plum tomatoes on the cutting board using the chef's knife, keeping all expressed juices.
Place the large heavy-bottomed Dutch oven over medium-low heat at 160°C (320°F), pour in 90 ml of extra virgin olive oil measured with the liquid measuring cup, and heat for 3 minutes until warm and shimmering.
Add the diced yellow onions and 2 g of fine sea salt measured with measuring spoons to the Dutch oven, then cook over medium-low heat at 150°C (300°F) for 20 minutes, stirring regularly with the wooden spoon until soft, translucent, and deeply golden.
Add the minced garlic to the Dutch oven and sauté over low heat at 130°C (265°F) for 2 minutes while stirring constantly with the wooden spoon until fragrant.
Add the diced red bell pepper and green bell pepper to the Dutch oven, cooking over medium-low heat at 150°C (300°F) for 15 minutes, stirring occasionally with the wooden spoon until tender and slightly collapsed.
Add the diced eggplant, diced zucchini, and 3 g of fine sea salt to the Dutch oven, stirring with the wooden spoon to coat the pieces in olive oil, and cook over medium-low heat at 150°C (300°F) for 15 minutes until the vegetables soften and absorb the oil.
Add the diced plum tomatoes with their juices, 3 fresh thyme sprigs, and 2 g of freshly cracked black pepper to the Dutch oven, stirring with the wooden spoon to incorporate all ingredients and dissolve any browned cooking juices from the bottom.
Cover the Dutch oven with its lid, adjust heat to low at 100°C (212°F), and simmer for 35 minutes, stirring every 10 minutes with the wooden spoon to ensure the mixture does not catch on the bottom.
Remove the lid from the Dutch oven and simmer uncovered over low heat at 100°C (212°F) for 20 minutes, stirring frequently with the wooden spoon, until liquid evaporates and the stew reduces into a thick, jammy compote with beads of olive oil pooling at the edges.
Remove the Dutch oven from the heat, remove and discard the thyme sprigs using the wooden spoon, stir in the remaining 3 g of fine sea salt to taste, and allow the stew to rest uncovered for 8 minutes before serving.
Chef's Notes
- Layering the vegetables into the pot sequentially is critical: slow-sweated onions build sweetness, peppers provide body, and eggplant and zucchini meld into a creamy background texture.
- The hallmark of traditional Catalan samfaina is the separation of olive oil at the final stage, signaling that the water has fully evaporated and the vegetable sugars have caramelized.
- Small, uniform dicing (around 1 cm) allows each component to collapse into a cohesive, spoonable texture rather than remaining as distinct roasted chunks.
- This dish develops remarkable depth over time; making it a day ahead allows the garlic, sweet peppers, and tomato acid to harmonize into an even richer stew.
Storage
Refrigerator: 5 days — Store in an airtight glass container. Cool within 2 hours of cooking before chilling.
Freezer: 3 months — Freeze in airtight freezer-safe containers with minimal headspace. Thaw overnight in the refrigerator.
Reheating: Reheat in a saucepan over medium heat, stirring occasionally, until hot and simmering throughout to an internal temperature of at least 74°C (165°F) as measured by a digital food thermometer.
Troubleshooting
The stew remains watery and thin after the covered simmering step
Cause: The tomatoes and squash held excess moisture, or the uncovered reduction heat was too weak to drive off steam
Fix: Increase burner heat to medium-low at 140°C (285°F) and simmer uncovered for an additional 8 to 12 minutes while stirring constantly until juices concentrate into a glossy sauce
Prevention: Ensure the lid is fully removed during the final phase and maintain a visible gentle simmer
The vegetables scorch or stick to the bottom of the pot
Cause: The cooking temperature was set too high or the pot was not stirred often enough during reduction
Fix: Immediately take the pot off the heat, gently ladle the unscorched top vegetables into another clean saucepan without scraping the burnt layer, and continue cooking on very low heat
Prevention: Use a heavy-bottomed Dutch oven and keep the flame low once moisture begins to drop
Cultural Context
Samfaina is an essential pillar of Catalan culinary tradition, deeply connected to the sofrito heritage of northeastern Spain. Originating as a seasonal celebration of summer harvest vegetables stewed gently in generous olive oil, it is enjoyed warm as an independent dish, served chilled at room temperature, or utilized as a luxurious bed for salt cod (bacallà) and roasted meats.
