A calamari in cassuola recipe is a rustic Italian seafood stew where squid simmers slowly in a tomato and white wine base until it turns tender. The name refers to the casserole-style pot (cassuola) the dish is cooked and served in, which keeps the liquid gently moving around the squid. This version gives you a practical method that avoids the rubbery texture most home cooks fight when they rush the timing.
You get a one-pot dish that needs only crusty bread to be a full meal, with layers of sweet tomato, briny squid, and a hint of fennel. The steps below are written so you can judge doneness by texture, not just the clock. If you enjoy oven snapper, the same Mediterranean flavor logic applies here. Making this calamari in cassuola at home is surprisingly straightforward once you know the key steps.
Dry white wine: Replace the 1/2 cup with an equal amount of dry vermouth or a splash of white wine vinegar cut with water (1 tbsp vinegar plus 7 tbsp water). Vermouth keeps the same acidity and aromatic lift, while the vinegar mix is sharper and less rounded. With vinegar you may want to add a pinch of sugar to soften the edge, and the broth will taste leaner without the alcohol's body. The calamari in cassuola works well for weeknight cooking when time is limited.
Fennel bulb: Swap with 1 cup thinly sliced celery plus 1/2 tsp fennel seed if you don't have the bulb. Celery gives a similar crunch-softening texture but loses the anise note, which the seed restores partially. The finished stew will be a little greener and less sweet, and the seeds should be crushed so they don't sit hard in the broth. Storing leftover calamari in cassuola correctly keeps it tasting good for days.
Crushed tomatoes: Use 2 cups peeled and chopped fresh tomatoes plus 1/4 cup tomato paste if canned isn't available. Fresh tomatoes add brighter acidity and a looser sauce, while paste deepens the color and thickens the liquid. You'll need to cook the mixture about 5 minutes longer to break down the fresh fruit before adding stock.

Seafood stock: Substitute the same amount of clam juice or plain water. Clam juice pushes the brine higher and pairs well with squid, while water keeps the tomato forward. With water, season carefully at the end since you lose the built-in salt from stock. If you enjoyed this, our contact is worth trying next.
Cut squid rings evenly so they cook at the same rate; ragged widths leave some chewy while others turn soft. A steady medium-low heat keeps the tomato from scorching on the bottom while the squid relaxes.
If your squid came frozen, thaw it fully in the fridge and pat dry, since surface ice dilutes the broth and cools the pot. For deeper flavor, roast the fennel separately until golden and crispy before adding it to the stew.
Use a pot that holds heat well, like enameled cast iron, to keep the simmer steady without hot spots. For safe seafood handling details, see seafood cooking guide from Simply Recipes.
Finish with a drizzle of raw olive oil at the table to brighten the stew after the long simmer dulls the first-pressed notes. Pair the plate with vegetable stir fry only if you want extra vegetables beyond the fennel.
Boiling the squid hard instead of simmering makes the protein seize and turn rubbery within minutes; keep the surface barely moving. never crowd the pan with too much squid at once if you scale up beyond 2 lbs without a bigger pot.
Adding salt too early to the tomato base can concentrate as it reduces, leaving the dish oversalted by the end. Season in the last 5 minutes after the broth volume settles.
Skipping the wine reduction step leaves an alcoholic sharpness; letting it cook off builds a rounder base. If you use espagnole sauce as a shortcut base, cut the stock since that sauce already carries weight.
Spoon the stew into shallow bowls with toasted sourdough to soak the broth. A side of cucumber bread adds a cool crunch that contrasts the warm tomato.
For a fuller table, serve over polenta or short pasta like orecchiette. A simple green salad with lemon dressing keeps the meal from feeling heavy after the squid and tomatoes.
Cool the stew to room temperature within 2 hours, then refrigerate in an airtight container for up to 3 days. Reheat on medium-low heat until steaming and the squid reaches 145°F internally.
The dish does not freeze well because the squid turns mushy after a freeze-thaw cycle. If you must freeze, do it before adding the squid and stir the seafood in fresh on reheating day. For another easy option, check out our crab meat weight.
Double the red pepper flakes and add 1 seeded diced jalapeño with the onion. The stew gains a clean heat that sits behind the tomato rather than on top, and the squid stays the same texture.
Replace crushed tomatoes with 2 cups chopped zucchini and 1 cup stock, then simmer as written. You get a lighter, broth-based cassuola where the fennel and wine lead instead of tomato acid.
Add 1/2 lb peeled shrimp in the last 5 minutes of simmer so they cook through without toughening. The combined seafood makes the pot closer to a mixed cacciucco and stretches to four servings.
Stir 1 tsp smoked paprika in with the garlic for a warm, campfire edge. The color deepens to brick red and the broth reads more like a Spanish stew than a plain Italian one. You might also like our hot toddy non.
Calamari in cassuola is a rustic one-pot Italian seafood stew where squid simmers slowly in a tomato and white wine base until tender. Served from the casserole pot with crusty bread, it delivers sweet tomato, briny squid, and a hint of fennel.
Pat the squid dry with paper towels to remove surface moisture. Cut the tubes into 1/2-inch rings using a sharp knife, and leave small tentacles whole. Even widths help the pieces cook at the same rate so none turn chewy while others go soft.
Set a 4-quart heavy pot over medium-low heat and add the 3 tbsp olive oil. Let the oil warm for about 30 seconds until it shimmers lightly but does not smoke. A well-heated heavy pot keeps the simmer steady later without hot spots.
Add the onion, garlic, and fennel with a pinch of salt to the pot. Cook at medium-low heat for 8 minutes, stirring occasionally, until the vegetables are softened and translucent rather than browned. This slow start builds a sweet base without scorching.
Stir in the 1/2 tsp red pepper flakes and cook for 30 seconds until fragrant. Keep the heat at medium-low so the flakes release aroma without burning. You should smell a gentle warmth rising from the pot.
Pour in the 1/2 cup dry white wine and raise the heat to medium. Scrape the bottom of the pot to lift any stuck bits, and let the liquid reduce by half, about 3 minutes, until the sharp alcohol smell cooks off and the base tastes rounder. Do not skip this step or the broth will stay sharp.
Add the crushed tomatoes, seafood stock, and 1 tsp salt to the pot. Bring the mixture to a gentle simmer at medium-low heat, with the surface barely moving. The broth should look loose and evenly red before the squid goes in.
Add the prepared squid to the simmering broth and cover the pot partially. Simmer at medium-low heat for 25–30 minutes until the squid is just tender when pierced with a fork and no longer opaque; reach an internal temperature of 63°C/145°F. Avoid a hard boil or the protein will seize and turn rubbery.
Stir in the parsley and basil off the heat to keep their color bright. Taste and adjust salt, then serve immediately from the pot with crusty bread. A drizzle of raw olive oil at the table wakes up the flavors after the long simmer.
