Marmitako: A Basque Bonito Stew That Warms the Soul

The wind was howling off the Bay of Biscay, and the air hung thick with the salty scent of the sea. I remember huddling in a small, family-run arrantzale (fisherman’s) restaurant in Getaria, Spain, my cheeks flushed from the cold. Then, a steaming bowl of Marmitako arrived – a rustic, fragrant stew brimming with tender potatoes and chunks of fresh, meaty bonito tuna. The rich aroma alone was enough to transport me, and that first spoonful… pure comfort. It was a simple, honest dish that spoke volumes about the Basque people and their deep connection to the ocean. I knew, right then, I needed to learn how to make it myself.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 4
• Yields: Approximately 6 cups
• Dietary Type: Gluten-Free, Dairy-Free

Ingredients

• 1 kg potato
• 500 g bonito tuna (also known as Thunnus alalunga)
• ½ onion
• 2 green bell peppers
• 1 ripe tomato
• 2 garlic cloves
• 2 choricero bell peppers (or ñoras)
• Fresh parsley
• Olive oil
• Salt and pepper to taste
• Optional: splash of white wine

Equipment Needed

• Large pot or Dutch oven
• Knife and cutting board
• Small bowl
• Spoon

Instructions

1. Begin by preparing the base. Finely chop the onion, green bell peppers, and garlic cloves.
2. Heat a generous drizzle of olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, green bell peppers, and garlic. Cook, stirring occasionally, until the onion is translucent and softened, about 5-7 minutes.
3. While the vegetables are cooking, prepare the potatoes. The traditional method for cutting the potatoes in Marmitako is to roughly start cutting a piece, but leave the last part uncut. Then, tear the potato chunk off with your hands. This is believed to release more of the potato starch, resulting in a thicker, more rustic stew. Cut all the potatoes in this irregular fashion.
4. Add the prepared potatoes to the pot with the sautéed vegetables. Continue cooking for a couple of minutes, stirring occasionally to coat the potatoes with the oil and vegetables.
5. Now, prepare the choricero peppers. These are dried peppers, so you’ll need to rehydrate them. Bring a small saucepan of water to a boil. Pour the boiling water over the choricero peppers in a heatproof bowl and let them soak for about 15-20 minutes, or until the flesh has softened and reconstituted.
6. Once the choricero peppers are rehydrated, carefully remove them from the water. Using the back of a knife or a spoon, scrape the flesh from the peppers, discarding the skins and seeds.
7. Add the choricero pepper flesh to the pot with the potatoes and vegetables.
8. Peel and chop the ripe tomato. Add the chopped tomato to the pot.
9. At this point, add a splash of white wine, if desired. Allow to cook off slightly for a minute. Then, add enough water to the pot to just cover the potatoes and vegetables.
10. Bring the stew to a simmer, then reduce the heat to low, cover the pot, and cook until the potatoes are fork-tender, about 15-20 minutes.
11. While the stew is simmering, prepare the bonito tuna. Cut the tuna into roughly 1-inch cubes. Season the tuna cubes generously with salt and pepper.
12. Once the potatoes are tender, gently stir in the cubed bonito tuna and chopped fresh parsley into the stew.
13. Cover the pot with the lid and remove it from the heat. Let the stew sit, covered, for about 5 minutes. This will allow the tuna to cook gently through the residual heat, keeping it tender and moist. Avoid overcooking the tuna, as it can become dry and tough.
14. After 5 minutes, check the seasoning. Adjust the salt and pepper as needed to taste.
15. Serve the Marmitako hot, garnished with a sprig of fresh parsley, if desired.

Expert Tips & Tricks

• For a richer flavor, use fish stock instead of water.
• Don’t overcook the bonito! It should be just cooked through.
• If you can’t find choricero peppers, you can substitute with a pinch of smoked paprika for a similar flavor profile.
• To make the stew thicker, you can mash some of the potatoes against the side of the pot.
• A bay leaf added during cooking can also add depth of flavor. Remember to remove it before serving.
• If the stew is too thick, add a little more water or fish stock to reach your desired consistency.

Serving & Storage Suggestions

Serve Marmitako hot in bowls, ensuring each serving has a generous portion of both potatoes and bonito tuna. A crusty loaf of bread on the side is perfect for soaking up the delicious broth.

Leftover Marmitako can be stored in an airtight container in the refrigerator for up to 2-3 days. The flavor actually improves overnight! To reheat, gently warm the stew in a saucepan over medium-low heat, stirring occasionally, until heated through. Be careful not to overcook the tuna during reheating. You can also reheat it in the microwave. It is not recommended to freeze Marmitako, as the potatoes can become mushy upon thawing.
