Ingredients

Why this recipe works

The slow cooker method provides a gentle, consistent heat that is ideal for large cuts of meat like pork roasts. By cooking slowly over several hours, the connective tissues within the meat gradually break down, which prevents the roast from becoming tough or dry.

This technique allows the flavors of the onion and oregano to penetrate deep into the pork, creating a dish that is deeply savory and tender.

Using tomato puree as a cooking liquid creates a natural braising environment that keeps the meat moist throughout the entire process. As the pork cooks, its juices combine with the tomato puree and the onions, resulting in a rich, flavorful sauce that requires no additional thickening.

This approach ensures that every bite of the meat is coated in a delicious, concentrated sauce without the need for complex ingredients or extra steps.

Notes and substitutions

When selecting a pork roast, look for a cut with a small amount of fat marbling, such as a pork shoulder or loin, to ensure the best texture after slow cooking.

Ensure the roast fits comfortably inside your slow cooker without overcrowding, which allows for even heat distribution. If the roast is too large, it may be cut into smaller, uniform pieces to ensure it cooks thoroughly within the recommended timeframe.

The quality of the tomato puree significantly impacts the final flavor of the dish, so choose a variety that contains only tomatoes or minimal additives. If you prefer a thicker sauce, you can remove the pork once finished and simmer the remaining sauce in a separate pan on the stove for a few minutes. Always ensure the pork is fully defrosted before adding it to the slow cooker for food safety reasons.

• Tomato puree: Crushed tomatoes or tomato sauce can be used if tomato puree is unavailable.
• Dried oregano: Dried thyme or Italian seasoning blend can be substituted for a different herbal profile.
