Tips for success
For a more robust flavor, consider lightly sautéing the onions in a small amount of oil before adding them to the slow cooker. This caramelizes the sugars, adding a layer of depth to the final sauce that complements the natural sweetness of the squid. However, this is optional and the recipe works perfectly well without this step if you are aiming for maximum efficiency and minimal cleanup.
If you prefer a slightly thicker sauce, you can remove the lid for the final 15 minutes of cooking. This allows some of the excess moisture to evaporate, concentrating the tomato flavor.
Be sure to keep a close eye on the squid during this stage to ensure it does not overcook. Serving with a side of crusty bread is highly recommended to soak up the remaining tomato and garlic sauce left on the plate.
Variations
- Spicy Tomato Squid: Add a teaspoon of red pepper flakes during the layering phase to introduce a subtle heat that cuts through the richness of the tomato coulis.
- Garlic-Forward Squid: Incorporate three cloves of thinly sliced fresh garlic along with the onions to enhance the aromatic profile and provide a stronger savory base for the sauce.
Storage and make-ahead
- Fridge
- Keep in an airtight container for up to 2 days.
- Freezer
- Freezing is not recommended as it significantly alters the texture of the squid.
- Reheat
- Gently reheat on the stovetop over low heat until warmed through, avoiding high temperatures to keep the squid tender.
Store any leftovers in an airtight container to maintain freshness. Allow the dish to cool for no more than two hours at room temperature before transferring it to the refrigerator.
Proper storage in the refrigerator keeps the squid tender for up to two days, though it is best enjoyed as soon as possible after cooking to retain the optimal texture and vibrant flavor profile of the tomato sauce.
This dish is excellent for preparation in advance, as the flavors continue to meld and deepen over time. You can assemble the ingredients in the slow cooker insert, cover it, and keep it in the refrigerator for up to 24 hours before cooking.
Simply remove it from the fridge and place it directly into the slow cooker base when you are ready to begin the cooking process, adding a few extra minutes to the initial cook time.
Serving ideas
Serve the squid hot, ideally in shallow bowls that can hold the generous amount of tomato sauce. A simple garnish of fresh parsley or a sprinkle of cracked black pepper can add a bright, fresh finish to the plate. Pair the dish with a side of steamed rice, polenta, or roasted potatoes to balance the richness of the tomato sauce and provide a hearty accompaniment to the tender seafood.
For a lighter meal, serve the squid over a bed of sautéed spinach or alongside a crisp green salad with a light vinaigrette. The acidity of the salad dressing complements the savory, herb-infused tomato sauce perfectly.
Regardless of the side dish, ensure the squid is served immediately while it is still warm and tender, as the texture can change if allowed to sit for too long after the cooking process is complete.
