Buttermilk fried calamari is a restaurant-style appetizer where tender squid rings are soaked in tangy buttermilk, coated in a seasoned flour mixture, and fried until golden and crisp. The buttermilk tenderizes the squid and helps the coating cling, while a hot oil fry creates a shatteringly crisp exterior that contrasts with the succulent interior. This recipe delivers consistently crunchy, never rubbery calamari at home, perfect for serving with lemon wedges and marinara sauce.
Ingredients
- 1 lb (450 g) fresh or thawed squid (calamari), cleaned
- 1 ½ cups (360 ml) buttermilk
- 1 cup (125 g) all-purpose flour
- ½ cup (60 g) cornstarch
- 1 tsp (5 g) garlic powder
- 1 tsp (5 g) onion powder
- 1 tsp (5 g) smoked paprika
- ½ tsp (2.5 g) cayenne pepper (optional, for heat)
- 1 tsp (5 g) salt
- ½ tsp (2.5 g) black pepper
- Vegetable or canola oil, for frying (about 4 cups / 960 ml)
- Lemon wedges, for serving
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Prepare the squid: If using whole squid, clean it by pulling the head and tentacles from the body. Remove the quill (the transparent cartilage) from inside the body, and rinse the body tube inside and out. Peel off any purple skin if desired. Cut the body into ½-inch (1.25 cm) rings. Leave tentacles whole or cut in half if large. Pat dry with paper towels.
- Marinate in buttermilk: Place the squid rings and tentacles in a bowl and pour the buttermilk over them. Stir to coat, cover, and refrigerate for at least 20 minutes (or up to 2 hours for extra tenderness).
- Make the coating: In a shallow dish or pie plate, whisk together the flour, cornstarch, garlic powder, onion powder, smoked paprika, cayenne (if using), salt, and black pepper.
- Heat the oil: Pour about 2 inches (5 cm) of oil into a heavy-bottomed pot or Dutch oven. Heat over medium-high until it reaches 350°F (175°C) on a deep-fry thermometer. If you don’t have a thermometer, test by dropping a small piece of bread into the oil – it should bubble vigorously and turn golden in about 30 seconds.
- Coat the calamari: Working in batches, lift a handful of squid from the buttermilk, letting excess drip off. Toss it into the flour mixture, coating thoroughly. Shake off any excess flour in a colander or by tossing in your hand. Place coated pieces on a wire rack while you coat the rest.
- Fry in batches: Carefully add a single layer of coated calamari to the hot oil (do not overcrowd). Fry for 2 to 3 minutes, turning occasionally, until golden brown and crispy. The squid should be opaque and cooked through. Use a slotted spoon to transfer to a paper-towel-lined plate. Repeat with remaining calamari, allowing the oil to return to 350°F (175°C) between batches.
- Serve immediately: Sprinkle with salt while hot, and serve with lemon wedges and your favorite dipping sauce.
Tips
- Dry squid thoroughly: Excess moisture on the squid will make the coating soggy and cause oil splatters. Pat the squid dry before adding to buttermilk, and shake off excess flour before frying.
- Don’t skip the buttermilk soak: Even 20 minutes makes a difference in tenderness. The acid in buttermilk helps break down the squid’s proteins, preventing a rubbery texture.
- Maintain oil temperature: If the oil drops too low, the calamari will absorb oil and become greasy. Fry in small batches and let the oil come back to 350°F (175°C) between batches.
- Use cornstarch: Cornstarch in the coating creates a lighter, crispier crust than flour alone. Don’t substitute all flour.
Serving Suggestions
Serve the fried calamari hot with lemon wedges and a side of warm marinara sauce for dipping. It also pairs well with aioli, spicy remoulade, or a simple garlic-yogurt sauce. For a complete appetizer spread, add a crisp green salad or serve alongside grilled vegetables.
Variations
- Spicy: Increase cayenne to 1 teaspoon or add a pinch of chili flakes to the flour mixture.
- Herbed: Add 1 teaspoon of dried oregano or thyme to the flour mixture for an Italian twist.
- Gluten-free: Replace all-purpose flour with a 1:1 gluten-free flour blend and ensure your cornstarch is gluten-free.
- Lemon-pepper: Add 1 tablespoon of lemon zest and 1 teaspoon of cracked black pepper to the flour mixture.
Storage and Reheating
Fried calamari is best enjoyed immediately, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, place on a baking sheet and warm in a 375°F (190°C) oven for 5-7 minutes, or until heated through and crisp. Avoid microwaving, which makes the coating soggy.
Frequently Asked Questions
How do I clean squid? If you buy whole squid, pull the head and tentacles away from the body. The insides will come with the head. Remove the tentacles from the head by cutting just above the eyes. Squeeze the tentacle base to pop out the beak (the hard, round mouth part) and discard. Remove the quill (a clear, plastic-like strip) from inside the body tube and rinse the tube inside and out. You can also ask your fishmonger to clean it for you.
Why is my calamari rubbery? Overcooking is the most common cause. Squid cooks in 2-3 minutes at 350°F (175°C); any longer and it becomes tough. Also, make sure your oil is hot enough – if it’s too cool, the squid will simmer rather than fry, leading to a chewy texture.
Can I use frozen squid? Yes, frozen squid works well. Thaw it in the refrigerator overnight, then pat it very dry before using. Do not refreeze thawed squid.
Can I make this ahead of time? The buttermilk marinade can be done up to 2 hours ahead. Coat and fry just before serving for the best texture. You can also coat the squid and refrigerate for up to 30 minutes before frying, but no longer, or the coating may become gummy.
What oil is best for frying? Use a neutral oil with a high smoke point, such as vegetable, canola, or peanut oil. Avoid olive oil, which has a lower smoke point and a strong flavor.
Is it safe to eat squid that is slightly translucent? No, squid must be cooked until opaque and firm. The safe minimum internal temperature for seafood is 145°F (63°C), but with calamari, visual cues (opaque and just firm) are more reliable due to the thin pieces. Always ensure it’s cooked through.
