Grilled Squid: How to Cook It on a Gas Grill Without Turning Rubbery

Grilled squid looks simple, but small mistakes can quickly make it tough and rubbery. When cooked correctly, squid should be lightly browned on the outside while remaining tender and juicy inside.

You do not need a complicated marinade. The key is a properly preheated cooking plate, thoroughly dried squid, enough space between the pieces and a short, controlled cooking time.

Grilled squid recipe

Ingredients

• 800 g (approximately 1.75 lb) cleaned squid of a similar size
• 1–2 tablespoons high-heat cooking oil
• 2 garlic cloves, finely chopped
• 2 tablespoons fresh chopped parsley
• 2–3 tablespoons extra virgin olive oil for finishing
• Juice of half a lemon
• Salt and freshly ground black pepper

Why does grilled squid become rubbery?

The most common cause is overcooking. Squid can also become tough when the cooking plate is not hot enough or when too much cold food is added at once.

Wet squid rapidly lowers the surface temperature. Instead of browning, the squid releases water and begins to steam in its own liquid. This extends the cooking time and increases the risk of a rubbery texture.

The most common mistakes are:

• Cooking squid while it is wet or still partially frozen
• Placing it on a cooking plate that is not fully preheated
• Overcrowding the cooking surface
• Moving the squid immediately after it touches the plate
• Allowing garlic or a sugary marinade to burn
• Cooking every size for the same amount of time
• Extending the cooking time because you are unsure whether it is ready

How to grill squid on a gas grill

1. Thaw and dry the squid completely

Thaw frozen squid slowly in the refrigerator. Clean and briefly rinse it, then dry it thoroughly with paper towels. Remember to dry the inside of each tube as well.

Removing surface moisture is essential. Wet squid cools the cooking plate and produces steam, making browning much more difficult.

2. Prepare evenly sized pieces

Small squid can be left whole. Larger tubes can be lightly scored on one side in a shallow diamond pattern, without cutting all the way through. Separate the tentacles and group the pieces by size because tentacles and smaller pieces usually cook faster.

3. Prepare the finishing sauce separately

Mix the chopped garlic, parsley, extra virgin olive oil and lemon juice in a small bowl. Keep this mixture away from the cooking plate until the squid is ready. Garlic can burn quickly on a hot steel plate and develop a bitter flavour.

4. Preheat the steel cooking plate

Preheat the clean cooking plate for approximately 10–15 minutes, or until the entire surface is evenly hot. If you are using an infrared thermometer, start at approximately 220–240°C (430–465°F).

The squid should sizzle immediately when it touches the plate. The oil should not be producing heavy smoke.

5. Apply only a thin layer of oil

Apply a very thin film of high-heat cooking oil to the plate. The squid should not be sitting in a pool of oil. If it has already been lightly oiled in a bowl, additional oil may not be necessary.

6. Cook in small batches

Arrange the squid in a single layer and leave some space between each piece. Do not move it during the first 60–90 seconds. This uninterrupted contact helps the surface brown. Overcrowding traps moisture and causes the squid to steam instead of sear.

7. Turn only once

For cleaned squid tubes approximately 10–15 cm (4–6 inches) long, begin with 2–3 minutes on the first side and 1–2 minutes on the second. Small squid and tentacles may be ready in 2–3 minutes total.

These times are a starting point rather than a guarantee. Larger pieces, a cooler plate or a heavier batch may require an adjustment.

The squid is ready when it is opaque, lightly golden-brown and firm but still flexible. For food safety, the thickest part should reach at least 63°C (145°F).

8. Season and serve immediately

Transfer the squid to a warm plate. Season it with salt and pepper, then spoon over the olive oil, garlic, parsley and lemon mixture. Serve immediately for the best texture.

Grilled squid cooking times

Cooking times are approximate. Squid size, starting temperature, cooking plate temperature, weather conditions and batch size can all affect the result.

Steel cooking plate or grill grate?

A smooth steel cooking plate is particularly practical for small squid and tentacles. Food cannot fall through the gaps, contact with the hot surface is consistent and the pieces are easy to turn.

A traditional grate creates distinctive grill marks and allows liquid to drain away, but smaller pieces require more careful handling. For mixed squid sizes and larger batches, a steel cooking plate often provides more predictable results.

Can squid be cooked on an electric grill?

Yes. The same basic method works on an electric grill with a smooth cooking plate: dry the squid thoroughly, fully preheat the grill and cook in small batches.

After cold food is added, an electric grill needs enough time and power to restore the cooking temperature. Avoid covering the entire surface at once. For squid, the stability and temperature of the cooking plate matter more than whether the heat comes from gas or electricity.

Fresh or frozen squid?

Both can produce excellent results. Frozen squid should be completely thawed in the refrigerator, drained and thoroughly dried before cooking. When buying fresh squid, check its appearance, smell and traceability. Keep it properly chilled until you are ready to cook.
