Why you’ll love this dish
Octopus on a tostada sounds fancy, but it’s approachable: quick to grill, bold in flavor, and wildly satisfying because of the contrast between tender seafood and crisp corn or flour shells. It’s perfect for backyard barbecues, tapas-style dinners, or when you want something lighter than tacos but more fun than a salad.
“Smoky char, a little heat, and creamy guac — the first bite is crunchy, the second is silky, and the whole thing disappears fast.”
Step-by-step overview
The process is straightforward: pat and season the octopus, grill briefly over high heat to get char and heat through, rest and slice. While it rests, whip up a simple guacamole and dice a few fresh aromatics. Assembly is immediate — spread, top, finish with jalapeño and lime. Expect about 15–20 minutes active time if your octopus is already tenderized.
What you’ll need
- 500 g octopus, cleaned and tenderized (see tips if using raw or frozen)
- 2 tablespoons olive oil
- 1 teaspoon smoked paprika
- 1 teaspoon chili powder
- 1 teaspoon ground cumin
- 1 clove garlic, minced
- Salt and freshly ground black pepper, to taste
- 4–6 tostada shells (corn for crispness; flour for sturdiness)
- 2 ripe avocados, mashed
- 1 small tomato, seeded and diced
- 1 small red onion, finely chopped
- 1 tablespoon lime juice
- Fresh cilantro, chopped
- Jalapeño slices (optional)
- Lime wedges for serving
Substitutions and notes: use pre-cooked octopus if you prefer (see FAQ). For gluten-free, choose corn tostadas. For a creamier guac, fold in a spoonful of sour cream or Mexican crema. For extra crunch, toast the tostadas briefly on the grill before assembling. If you’d like another crunchy handheld idea to pair with seafood, consider the irresistible easy grilled cheese burrito in your menu rotation.
Step-by-step instructions
- Preheat the grill to medium-high (about 400–450°F) and oil the grates so the octopus doesn’t stick.
- In a small bowl, whisk together the olive oil, smoked paprika, chili powder, ground cumin, minced garlic, and a pinch of salt and pepper.
- Pat the octopus dry with paper towels. Toss it in the spice-oil mixture to coat evenly. Let it rest 5–10 minutes so the flavors adhere.
- Place the octopus on the hot grill. Cook 4–5 minutes per side, watching for good char and that the octopus is heated through. You want quick high heat rather than slow cooking here — we’re finishing cooked/tenderized octopus, not tenderizing it on the grill.
- Remove the octopus from the grill and let it rest 3–4 minutes. Slice against the grain into bite-sized pieces.
- Make the guacamole: mash the avocados and fold in the diced tomato, chopped red onion, lime juice, cilantro, and salt to taste.
- Spread a generous layer of guacamole on each tostada shell, top with sliced grilled octopus, add jalapeño slices if you like heat, and serve immediately with lime wedges.
Best ways to enjoy it
Serve these tostadas as a shared starter or as the main event with a couple of sides. Good companions:
- A crisp Mexican lager or a citrus-forward white wine (Albariño or Sauvignon Blanc).
- Grilled corn salad, pickled red onions, or a simple cabbage slaw for crunch and acidity.
- Garnish options: crumbled queso fresco, a drizzle of crema, or a smattering of microgreens for color.
- For a party, set up an assembly station so guests can customize heat and toppings.
Storage and reheating tips
Store components separately for best texture. Keep grilled octopus in an airtight container in the fridge for 2–3 days. The guacamole is best eaten within 24 hours; press plastic wrap directly on its surface to slow browning. Tostada shells should be stored dry at room temperature in a sealed bag to stay crisp.
To reheat octopus, warm gently on a hot grill or in a skillet over medium heat for 1–2 minutes per side — just enough to heat through and revive char without drying. Avoid microwaving, which makes it rubbery. Cooked octopus can be frozen up to 2 months; thaw overnight in the fridge before reheating.
Pro chef tips
- If your octopus isn’t pre-tenderized, simmer it gently for 45–60 minutes (depending on size) until tender, or use a pressure cooker for 20–25 minutes, then cool before grilling.
- Patting the octopus very dry before it hits the grill ensures better charring and prevents steaming.
- Don’t skimp on rest time after grilling — a short rest settles juices and makes slicing cleaner.
- To tame heat, remove seeds from jalapeños and reduce chili powder to 1/2 teaspoon.
- Use tongs and a flat spatula when flipping to keep pieces intact.
Creative twists
- Smoky citrus: add orange zest to the spice mix and finish with a squeeze of orange-lime for brightness.
- Crunch swap: replace tostada shells with lettuce cups for a low-carb version.
- Heat variations: swap smoked paprika for chipotle powder for smokier heat, or use ancho chili for a milder, fruity warmth.
- Vegetarian option: grill thick slices of king oyster or portobello mushrooms with the same spice rub for a meaty, plant-based tostada.
- Latin fusion: top with pickled red onion, a drizzle of salsa verde, and a sprinkle of cotija for a tangy finish.
Common questions
Q: Do I need to tenderize the octopus before grilling?
A: If your octopus is labeled “tenderized” or pre-cooked, you can grill it directly. If it’s raw and untreated, you’ll need to simmer or pressure-cook it until tender (see tips: simmer 45–60 minutes or pressure cook 20–25 minutes) before finishing on the grill.
Q: Can I use frozen octopus?
A: Yes. Thaw it completely in the refrigerator overnight. Some frozen octopus is already tenderized by freezing; check packaging. If it seems firm, follow the tenderizing step before grilling.
Q: How spicy is this recipe and how can I adjust the heat?
A: The base rub has moderate heat from chili powder. To make it milder, reduce chili powder to 1/2 teaspoon and omit jalapeño slices. To increase heat, add more chili powder, a pinch of cayenne, or serve with pickled serranos.
Q: Is it safe to eat leftover grilled octopus?
A: Yes, store cooked octopus in the refrigerator within two hours of cooking and consume within 2–3 days. Reheat until hot throughout. Discard if you notice off smells or sliminess.
Q: Can I prepare any parts ahead of time?
A: Make the guacamole up to a day ahead (press plastic wrap on the surface). Season the octopus and keep it chilled; grill just before serving for best texture.
