Before you start

Before beginning, ensure that the squid is thoroughly cleaned and sliced into uniform rings to promote even cooking. Have the onion thinly sliced and the garlic minced finely to allow their flavors to permeate the liquid effectively.

Prepare all ingredients in advance so that assembling the slow cooker is a swift and organized process. Ensure the slow cooker interior is clean and ready for the ingredients, and double-check that you have the necessary measuring tools on hand for the wine.

Ingredients at a glance (5)
  • 1 lb raw squid rings
  • 1 onion, sliced
  • 3 cloves garlic, minced
  • 1 tbsp herbes de Provence
  • 1/2 cup dry white wine

Instructions

Preparation and assembly

  1. Prepare the slow cooker
    Place the raw squid rings into the bottom of the slow cooker vessel. Ensure the rings are distributed evenly to allow for consistent cooking throughout the process.
    Look for The squid should cover the base of the insert.
    Tip Ensure the squid is cleaned thoroughly before adding to the cooker.

The squid, onions, and garlic are arranged in the cooker, and the wine is poured over the top. Everything should look clean and ready for the slow cooking process. Ensure the lid is securely placed on the cooker before activating the low-heat setting to start the braising phase.

Slow braising

  1. Add aromatics and liquid
    Scatter the sliced onion and minced garlic over the squid. Sprinkle the herbes de Provence evenly over the top of the mixture, then pour the dry white wine over everything.
    Look for The wine should partially submerge the ingredients.
    Tip Use a dry white wine like Sauvignon Blanc or Pinot Grigio for the best flavor balance.

During the cooking time, the kitchen will fill with the savory aroma of garlic, herbs, and wine. The liquid will begin to pool at the bottom as the onions soften. There is no need to stir the mixture during this time, as the gentle heat will naturally circulate the flavors throughout the vessel.

Final check and serving

  1. Slow cook and serve
    Cover the slow cooker and cook on low for 3 hours. Once the time is up, ensure the calamari has reached an internal temperature of 145°F (63°C) to be fully cooked and tender.
    Look for The calamari should be opaque and tender.
    Safe temperature 145°F (63°C) internal temperature (shellfish)
    Tip Do not overcook, as this can make the squid rubbery.

After the cooking cycle, the calamari should appear opaque and tender. The liquid should be aromatic and slightly reduced. Check the internal temperature to ensure it has reached 145°F (63°C) before transferring the mixture to a serving dish to enjoy immediately while steaming hot and flavorful.

Common mistakes

A common mistake is cooking the calamari for too long, which can quickly turn the tender rings into rubbery bites. Always stick to the recommended low-heat setting to maintain a gentle cooking pace.

Another error is neglecting to balance the wine with enough aromatics, which can leave the sauce tasting one-dimensional.

Ensure the garlic and onions are distributed properly rather than clumped together, as this prevents uneven flavor distribution throughout the dish. Avoid overcrowding if possible to ensure every piece cooks through.

How to tell it’s done

The calamari is perfectly cooked when it becomes opaque, tender, and easily pierced with a fork. It should not be chewy or rubbery. Use a digital probe thermometer to ensure the squid has reached an internal temperature of at least 145°F (63°C), which is the standard safety requirement for cooked shellfish.

When done, the liquid should be fragrant and the onions should have softened into the sauce, creating a cohesive and savory poaching broth that complements the delicate nature of the squid.
