You are doing it all wrong. Here’s the right way to use your slow cooker

Dairy products such as milk, cheese, and cream can curdle or separate when cooked for long periods. To prevent this from happening, it’s best to add these ingredients in the last hour of cooking. This ensures that they are fully incorporated into the dish without compromising the texture.
If you’re making a creamy soup or sauce, consider using evaporated milk or a cornstarch slurry, as these tend to hold up better under prolonged heat. These substitutes can provide the creamy texture you desire without the risk of curdling.
5. Choose the Right Cut of Meat for Slow Cooking
Not all cuts of meat are created equal, especially when it comes to slow cooking. Tougher cuts of meat like chuck roast, pork shoulder, and brisket are ideal for slow cooking, as the extended cooking time allows the connective tissues to break down, resulting in tender, flavorful meat.
Avoid lean cuts like chicken breast or pork tenderloin, which can become dry and tough when cooked for long periods. Instead, opt for bone-in, skin-on cuts that will retain moisture and impart additional flavor to your dish.
