This easy and great-tasting clam chowder cooks in the slow cooker in just 4 hours. Made with potatoes, milk, bacon (or salt pork), and canned minced clams, this thick and creamy recipe is satisfying and full of flavor. Clams are a great source of protein at a relatively low caloric cost, as a three-ounce serving has about 125 calories, but is packed with 22 grams of protein, plus several vitamins and minerals. (An egg has six grams of protein, for comparison.)

We use bottled clam juice as the cooking liquid, but water or chicken stock may be used instead. If you use salted or low-sodium chicken broth, go easy on any additional salt. Taste halfway through the cooking process, and once the chowder is done add more if needed. 

This creamy soup is a great lunch or dinner on a cold day, and because it's made in the crock pot, it can be transported easily to potlucks. Serve with oyster crackers, saltines, or French bread.


  • 4 (6 1/2-ounce) cans minced clams, with juice
  • 6 ounces salt pork, or bacon, diced
  • 1 onion, chopped
  • 6 to 8 medium potatoes, peeled and cubed
  • 3 cups water, or low-sodium chicken broth or clam juice
  • 2 1/2 teaspoons salt, or to taste
  • 1/4 teaspoon pepper
  • 4 cups half-and-half, cream, or whole milk, divided
  • 4 tablespoons cornstarch

Steps to Make It

  1. Gather the ingredients.

  2. If necessary, chop or slice the clams into bite-sized pieces.

  3. In a skillet, fry the ham or diced bacon and onion until golden brown. Drain and set aside. Alternately, if you have a crockpot with a sauté feature, fry the bacon right in the crock pot, then drain some of the fat.

Variations and Substitutions

You can add one or more of the following ingredients or use one of our suggested substitutions for different and equally delicious clam chowders:

  • For extra crunch and texture add 1/2 cup of chopped celery to the skillet along with the onions.
  • Add a teaspoon of chopped fresh garlic when the onions and bacon are browned and cook for about 1 more minute. 
  • Use diced lean ham instead of pork or bacon to cut down on calories and sodium.
  • For a richer chowder, use only half-and-half instead of milk.
  • Fry a few extra strips of bacon, refrigerate while the chowder cooks, and crumble them when cold so you can use them as a garnish to top the finished chowder.
  • Use sliced green onion tops, shredded mild cheese, or chopped chives to garnish each serving.
