Ingredients You Need

Octopus and braising base

• 2 to 2.5 pounds whole octopus, cleaned
  • Ask the fishmonger to clean it to save time.
  • Frozen octopus works great and often turns more tender after thawing.
• 1 yellow onion, quartered
• 1 small carrot, cut into chunks
• 2 celery stalks, cut into chunks
• 6 garlic cloves, smashed
• 2 bay leaves
• 1 teaspoon whole black peppercorns
• 1 teaspoon smoked paprika
• 1 teaspoon sweet paprika
• 1 teaspoon kosher salt, plus more to taste
• 2 tablespoons olive oil
• 1 small lemon, halved
• 4 to 5 cups water, enough to cover the octopus in the pot

Smoky romesco sauce

• 2 large roasted red bell peppers, peeled and seeded
  • Use jarred roasted peppers in water for a pantry shortcut; I like the Divina or Mezzetta brands.
• 1 medium ripe tomato, cored and chopped
  • Use 1/2 cup canned fire-roasted tomatoes if fresh tomatoes look sad.
• 1/3 cup blanched almonds or Marcona almonds
  • Use roasted almonds and skip extra toasting time.
• 1 slice crusty bread, toasted
  • Use gluten free bread if needed.
• 2 garlic cloves
• 1 tablespoon sherry vinegar
  • Red wine vinegar works as a backup.
• 1 teaspoon smoked paprika
• 1/4 teaspoon cayenne pepper or hot paprika, to taste
• 1/3 cup extra virgin olive oil
• 1/2 teaspoon kosher salt, more to taste
• Freshly ground black pepper, to taste

Finishing touches

• 2 tablespoons olive oil, for searing
• Fresh parsley, chopped
• Lemon wedges, for serving
• Flaky sea salt, to finish

Equipment list

• Large heavy pot or Dutch oven with lid
• Tongs
• Cutting board and sharp knife
• Blender or food processor for the romesco sauce
• Small skillet for toasting nuts and bread
• Serving platter or shallow bowl
• Paper towels for patting the octopus dry

Quick Tips & substitutions

• Pat the octopus very dry before searing so the edges caramelize instead of steaming.
• Use frozen octopus if fresh looks questionable; thaw it overnight in the fridge.
• Swap almonds with hazelnuts or walnuts if that is what you have.
• Use jarred roasted peppers to save time and keep prep simple.
• Adjust the cayenne in the romesco sauce to control the heat level.
• Cut the braised octopus into bite-size pieces before searing to get more crispy edges.
• Use gluten free bread in the sauce if you need a gluten free version.
• Make the romesco sauce a day ahead and chill it so the flavors deepen.

How to Make Braised Octopus with Smoky Romesco Sauce Recipe

Step 1: Prep and clean the octopus

Rinse the octopus under cold water and check for any leftover bits of beak or innards. Trim any tough bits around the head and discard them. Pat the octopus very dry with paper towels so it browns better later.

Step 2: Build the braising base

Heat 2 tablespoons olive oil in a large Dutch oven over medium heat. Add onion, carrot, celery, and smashed garlic cloves, then cook until the vegetables soften and smell sweet, about 5 to 7 minutes. Stir in smoked paprika, sweet paprika, bay leaves, peppercorns, and 1 teaspoon kosher salt.

Step 3: Braise the octopus

Nestle the octopus into the pot on top of the vegetables. Squeeze the lemon halves over the top, then drop the squeezed halves into the pot. Pour in enough water to just cover the octopus, then bring the liquid to a gentle simmer over medium heat.

Lower the heat to maintain a steady, gentle simmer. Cover the pot and cook the octopus until it turns very tender when you pierce the thickest part with a knife, about 60 to 75 minutes. Check a couple of times and skim any foam from the surface.

Step 4: Cool and slice the octopus

Lift the octopus out of the braising liquid with tongs and set it on a cutting board to cool slightly. Strain the braising liquid and save a cup of it in case you want to thin the romesco sauce or moisten leftovers. Once the octopus cools enough to handle, cut the tentacles away from the head and slice them into 1 to 2 inch pieces.

Step 5: Toast nuts and bread

Set a small skillet over medium heat. Add the almonds and toast them, shaking the pan often, until they turn golden and fragrant, about 3 to 4 minutes. Add the bread slice to the same pan and toast it until it turns golden on both sides.

Let the nuts and bread cool slightly so they blend more easily. Break the bread into chunks before you add it to the blender or food processor.

Step 6: Blend the smoky romesco sauce

Add roasted red peppers, tomato, toasted almonds, toasted bread, garlic, sherry vinegar, smoked paprika, cayenne, and 1/2 teaspoon kosher salt to a blender or food processor. Pulse until the mixture looks chunky. With the motor running, stream in the olive oil and blend until the sauce looks thick and smooth but still holds some texture.

Taste and adjust with more salt, vinegar, or cayenne as you like. If the sauce looks too thick, loosen it with a spoonful or two of the reserved braising liquid or a splash of water.

Step 7: Sear the braised octopus

Heat 2 tablespoons olive oil in a large skillet over medium high heat. Pat the sliced octopus dry again, then add it to the hot pan in a single layer. Cook without moving it for 2 to 3 minutes so the edges char and crisp.

Flip the pieces and cook another 2 to 3 minutes until you see browned spots and the pieces heat through. Season with a pinch of salt and black pepper.

Step 8: Plate and finish

Spread a generous layer of smoky romesco sauce over a warm serving platter or shallow bowl. Arrange the seared octopus pieces on top of the sauce. Sprinkle with chopped parsley and flaky sea salt.

Serve with lemon wedges on the side so everyone can squeeze fresh citrus over their plate. Spoon extra romesco sauce into a small bowl and set it at the table for dipping.

Recipe Variations

• Gluten free: Use gluten free bread in the romesco sauce and check that your smoked paprika and vinegar list gluten free on the label.
• Dairy free: The base recipe already avoids dairy, so you do not need changes.
• Low carb: Skip the bread in the romesco sauce and add a few extra almonds to keep the texture thick.
• Spicier: Add extra cayenne or a small roasted hot pepper to the sauce.
• Herb twist: Add fresh thyme or rosemary to the braising liquid for a more herbal note.
• Grill finish: After braising, finish the octopus on a hot grill instead of a skillet to add more smoky flavor.

Ways to Serve Braised Octopus with Smoky Romesco Sauce Recipe

• Spoon the octopus and romesco over garlicky mashed potatoes.
• Serve with crusty bread or warm flatbread to scoop up the sauce.
• Pair with a simple green salad with lemon and olive oil.
• Serve as a tapas plate alongside marinated olives and roasted vegetables.
• Add the octopus pieces and romesco to warm cooked rice or quinoa for a bowl-style meal.

Storage Success

Cool leftover braised octopus and romesco sauce to room temperature, then store them in separate airtight containers in the fridge. The octopus keeps well for up to 3 days, and the romesco sauce tastes even better on day two or three. Reheat the octopus gently in a skillet over medium heat with a splash of the reserved braising liquid or water so it stays tender. Use the leftover romesco as a dip for vegetables or a spread for sandwiches so nothing goes to waste.

• 1/3 cup extra-virgin olive oil
• Kosher salt, to taste

• 1 tablespoon chopped fresh parsley
• Lemon wedges

Instructions

 

1. Rinse the cleaned octopus under cold water. In a large heavy pot, combine onion, carrot, celery, garlic, bay leaves, peppercorns, white wine, and enough water to fully submerge the octopus.
2. Squeeze the lemon halves into the pot and add the halves as well. Bring the liquid to a simmer over medium heat.
3. Add the octopus, reduce heat to low, and cover. Gently simmer (do not boil) for 60–75 minutes, or until the octopus is very tender when pierced with a knife.
4. Let the octopus cool in the braising liquid for 15–20 minutes, then remove and drain well. Pat dry with paper towels. Cut the tentacles apart and, if large, cut into smaller portions.
5. Just before serving, heat 2 tablespoons olive oil in a large skillet over medium-high heat. Season the octopus lightly with salt and sear for 2–3 minutes per side until browned and slightly crisp at the edges.

1. In a food processor, combine roasted red peppers, roasted tomatoes, almonds, toasted bread, garlic, smoked paprika, and red pepper flakes if using. Pulse until finely chopped.
2. Add the red wine vinegar and a pinch of salt. With the machine running, slowly drizzle in the olive oil until the sauce is thick, smooth, and spoonable. Adjust seasoning with additional salt or vinegar to taste.

1. Spoon a generous pool of romesco sauce onto each plate.
2. Arrange the seared octopus pieces over the sauce. Drizzle with a little extra-virgin olive oil if desired and sprinkle with chopped parsley.
3. Serve immediately with lemon wedges on the side for squeezing over the octopus.
