Most cooks know the squid rule: hot and fast, or low and slow—never in between. Yet as 2026 unfolds, the low-and-slow path remains underrated. A gentle braise transforms squid into something silky, savory, and deeply satisfying, and it usually takes only about 30 minutes of simmering. That is the kind of long cooking that fits a weeknight. This Mediterranean-style braise combines onions, garlic, white wine, tomatoes, olives, harissa, and lemon zest for a dish that tastes like a slow Sunday project but comes together in 45 minutes.

The Science of Tender Squid

Why does squid turn rubbery? The answer lies in its structure. A squid's tubular body and tentacles are made mostly of thin layers of muscle fiber and collagen. Quick cooking works because the short exposure to heat prevents those muscle fibers from contracting to the point of toughness. Long cooking works for a different reason: it breaks down the collagen that connects the muscle fibers, turning it into gelatin. That gelatin has a much softer texture, so the squid becomes tender rather than chewy. Long-cooked squid is less plump and juicy than quickly cooked squid, but its tenderness more than makes up for that. Its flavor also becomes more pronounced, growing into a rich, seafood-y savoriness that infuses whatever liquid it is braised in.

A Mediterranean Braise with North African Punch

This recipe takes a Mediterranean approach, then adds complexity with harissa, the North African spiced chile paste, and fresh lemon zest. The result is a stew with warmth, acidity, and depth. Here is what goes into it:

Step-by-Step: Building the Braise

1. 🔪 Cut the cleaned squid bodies into 1/2-inch rings. Divide large tentacles into halves lengthwise. The squid shrinks a lot during longer cooking, so avoid slicing it too thinly.

2. 🧅 In a large saucepan, heat the olive oil over medium-high heat until shimmering. Add the onion and garlic and cook, stirring, until softened but not browned, about 4 minutes.

3. 🍷 Add the white wine and squid. Bring to a simmer and cook, stirring occasionally, until the raw alcohol smell has mostly cooked off, about 3 minutes.

4. 🍅 Stir in the hand-crushed tomatoes with their juices, the thyme sprigs, and the drained olives. Return to a simmer.

5. 🔥 Lower the heat to maintain a gentle simmer. Cook, stirring occasionally, until the squid is tender, about 30 minutes. Discard the thyme.

6. 🌶️ Stir in the harissa paste and lemon zest. Season with kosher salt and black pepper.

7. 🌿 Finish with minced fresh parsley. Serve hot.

What to Serve With Long-Cooked Squid

A braise this rich needs a base that can soak up the sauce. The recipe suggests fregola, the toasted Sardinian pasta, but many cooked grains work well. Here are a few options:

Make-Ahead and Leftovers

This squid can be braised up to 4 days in advance and kept refrigerated in a sealed container. To serve, thin it slightly with water and reheat gently. Like many stews, it may taste even better the next day as the flavors meld. The recipe yields 4 to 6 servings and takes about 45 minutes total, including prep and cooking.

Why This Braise Deserves a Spot in 2026

So why do so many cooks still avoid long-cooked squid? Habit, mostly. The old warning about rubbery squid has overshadowed the fact that long cooking can be only 30 minutes. In 2026, with harissa widely available and weeknights as hectic as ever, this braise is a reminder that long-cooked can be a relative term. It is fast enough for a weeknight, elegant enough for guests, and forgiving enough for meal prep. For anyone who loves seafood but has been stuck in a speedy-squid rut, this is the recipe that breaks the cycle.
