Ingredients You’ll Need

Octopus & Braising Aromatics

2 to 3 pounds whole octopus, cleaned
- Fresh or frozen both work; frozen often turns out more tender.
1 small onion, quartered
1 carrot, cut into chunks
2 celery stalks, cut into chunks
4 garlic cloves, smashed
2 bay leaves
1 teaspoon whole black peppercorns
1 teaspoon kosher salt
2 to 3 sprigs fresh thyme or oregano
1 small lemon, halved
Water, enough to cover the octopus in the pot

Pantry shortcut: You can toss in 1 teaspoon smoked paprika into the braising liquid for extra smoky flavor, especially if you love that grilled vibe.

Smoky Romesco Sauce

You can use jarred roasted peppers and canned tomatoes to save time.

2 large roasted red bell peppers
- Use jarred roasted peppers in brine for convenience; drain them well.
1 medium ripe tomato, cored and chopped
- In winter, use ½ cup good quality canned crushed tomatoes.
⅓ cup blanched almonds or Marcona almonds
- Use roasted unsalted almonds if you already have them.
1 slice day-old crusty bread, torn
- Use gluten-free bread if needed.
2 garlic cloves, roughly chopped
2 to 3 tablespoons sherry vinegar
- Red wine vinegar works in a pinch.
½ to ¾ teaspoon smoked paprika
- Use Spanish pimentón if you have it.
¼ teaspoon cayenne pepper or hot smoked paprika, to taste
⅓ to ½ cup extra-virgin olive oil
½ teaspoon kosher salt, plus more to taste
Freshly ground black pepper, to taste

For Searing & Finishing

2 tablespoons olive oil
1 tablespoon butter (optional, for extra browning)
Lemon wedges, for serving
Chopped fresh parsley, for garnish
Flaky sea salt, to finish

Equipment List

Large heavy pot or Dutch oven, 5 to 6 quart
Cutting board and sharp chef’s knife
Tongs
Blender or food processor for the romesco sauce
Large skillet or grill pan for searing
Fine mesh strainer (optional, for a smoother sauce)
Measuring cups and spoons

Tips & Tricks

Rinse the octopus under cold water and pat it very dry so it browns nicely later.
Use frozen octopus if you feel nervous about freshness; many seafood markets freeze it at peak quality.
Add a wine cork to the braising liquid if you like; some cooks swear it helps tenderness, and it never hurts.
Keep the braise at a gentle simmer, not a rolling boil, so the octopus stays tender.
Start checking tenderness at 45 minutes; different octopus sizes cook at different speeds.
Blend the romesco sauce until smooth, then adjust thickness with a splash of water or extra olive oil.
Taste the romesco at the end and tweak salt, vinegar, and heat so it hits that tangy, smoky, slightly spicy balance.
Chill the braised octopus in the fridge before cutting if you want super clean slices and easy handling.
Pat the cooked octopus very dry before searing so you get a deep golden crust instead of steaming.
Warm the romesco gently on low or serve it at room temperature so the flavors stay bright and bold.

How to Make Braised Octopus with Smoky Romesco Sauce Recipe

Prep the Octopus

Rinse the octopus under cold running water and remove any visible beak or leftover innards.
Pat it dry with paper towels and set it on a plate while you prep the aromatics.
Cut the onion, carrot, and celery into large chunks and smash the garlic cloves.

Braise the Octopus

Place the octopus in a large pot or Dutch oven.
Add onion, carrot, celery, smashed garlic, bay leaves, peppercorns, thyme or oregano, and lemon halves.
Sprinkle in the kosher salt and any optional smoked paprika.
Pour in enough water to cover the octopus by about an inch.
Bring the pot to a gentle simmer over medium heat, then lower the heat so the liquid barely bubbles.
Cover the pot and cook for 45 to 75 minutes, depending on the size of the octopus.
Start checking at 45 minutes by piercing the thickest part of a tentacle with a knife; it should slide in easily.
Once tender, turn off the heat and let the octopus cool in the braising liquid for 15 to 20 minutes to stay juicy.

Make the Smoky Romesco Sauce

While the octopus braises, add roasted red peppers, tomato, almonds, torn bread, garlic, sherry vinegar, smoked paprika, cayenne, salt, and black pepper to a blender or food processor.
Pulse a few times to break everything down.
With the motor running, stream in ⅓ cup olive oil until the sauce looks thick and creamy.
Check the texture; add more olive oil or a tablespoon of water at a time if it feels too thick.
Taste and adjust with more salt, vinegar, or cayenne until the romesco tastes smoky, tangy, and slightly spicy.
For a silkier texture, push the sauce through a fine mesh strainer, then set it aside at room temperature.

Portion the Braised Octopus

Lift the octopus out of the braising liquid and set it on a cutting board.
Pat it dry thoroughly with paper towels; moisture fights against browning.
Use a sharp knife to separate the tentacles from the head.
Leave the tentacles whole for a dramatic plate or cut them into 2 to 3 inch pieces for easier serving.
Trim any gelatinous bits that you do not enjoy, although many people love that texture.

Sear the Octopus

Heat a large skillet or grill pan over medium-high heat.
Add olive oil and butter, if using, and swirl until hot and shimmering.
Lay the octopus pieces in a single layer without crowding; cook in batches if needed.
Sear each side for 2 to 3 minutes until the edges char slightly and the surface turns deep golden.
Transfer the seared octopus to a plate and sprinkle with a pinch of flaky sea salt.

Plate and Serve

Spoon a generous pool of smoky romesco sauce onto each plate.
Arrange the seared octopus pieces on top of the sauce.
Garnish with chopped fresh parsley and a squeeze of fresh lemon juice.
Serve extra romesco and lemon wedges on the side so everyone can adjust to taste.

What to Serve with it?

This Braised Octopus with Smoky Romesco Sauce Recipe pairs beautifully with simple sides that let the sauce shine. Try roasted potatoes or crispy smashed potatoes, plus a bright green salad with lemony vinaigrette. Grilled or steamed vegetables like asparagus, green beans, or zucchini balance the richness. Warm crusty bread or toasted flatbread also works great to scoop up every last bit of romesco.

Storage Options

Store leftover octopus and romesco sauce separately in airtight containers in the fridge for up to 3 days.
Chill the octopus pieces flat on a tray first, then transfer them to a container so they do not stick together.
Freeze the braised (not seared) octopus in a freezer-safe bag for up to 2 months; thaw overnight in the fridge before searing.
Freeze romesco sauce in small containers or ice cube trays for up to 2 months, then thaw in the fridge and stir well.
Reheat octopus gently in a hot skillet with a little oil for 1 to 2 minutes per side so it warms through without turning rubbery.
Warm romesco on low heat or let it come to room temperature, then stir and taste before serving.
