Slow Cooker Clam Chowder is so easy to make with a deliciously creamy, briny flavor mixed with smoky crispy bits of bacon and rich buttery yukon potatoes.
Slow Cooker Clam Chowder
Slow Cooker Clam Chowder is an easy fall soup you’ll enjoy as well as great gameday food you can make for a crowd. We often serve this clam chowder in a bread bowl, but even more often I pile it into a giant bowl and throw a huge handful of oyster crackers on top.
The flavors in the soup scream “hey its not swimsuit weather anymore!” with half and half, bacon, potatoes and clams, but just a small bowl will keep you warm and full for HOURS. We went skiing last winter a lot and one of the few meals I made in our hotel mini kitchen was this soup. After a long day of playing in the snow, you’re going to love this thick, rich bacon filled chowder. Can I just be super bold and say this is the best clam chowder in the world?
The recipe for this clam chowder actually started as a back of the can recipe that I’ve added and subtracted ingredients from over the years. Since then I’ve actually entered this chowder into multiple office contests when I worked in an office and in one local soup challenge. The results, this is an award winning clam chowder recipe! I have the free movie tickets I won to prove it!
Tips for making this Slow Cooker Clam Chowder:
- Get your bacon nice and crisp but not browned. The browned bacon will add an overcooked flavor to the soup.
- You can swap out the half and half for milk, you may need to mash some of the potatoes to add thickness to the soup.
- I’ve also made the Clam Chowder with heavy cream before and it is an indulgent treat!
- You can top with parsley as I have or chopped chives which add flavor as well as freshness.
- Want to make this clam chowder even better? My secret flavor boost is Clam Base. It isn’t something people generally keep in their kitchens so I left it as an optional ingredient in the directions, but I always add it!
- If you don’t want to buy Clam Base you can also buy Clam Juice to replace the water.
What is the difference between New England Clam Chowder and Manhattan Clam Chowder?
Manhattan Clam Chowder uses tomatoes and is often referred to as Manhattan Red Chowder.
Q&A about the vegetables in this Slow Cooker Clam Chowder:
- I used Yukon potatoes for their rich and buttery texture. You can also use red potatoes.
- I added celery because I love the added flavor of it and it reminds me of a lobster roll. You can also add carrots.
- For a huge flavor boost sauté your veggies in the bacon fat before adding (they will look less pretty in the soup).
- Garlic is a flavor not added to some clam chowders but I find it adds a great flavor to the soup which still tastes like your favorite classic chowder.

Tools used in the making of this Slow Cooker Clam Chowder:
3 Qt. Slow Cooker: The perfect size for side dishes for 10-12 people, this slow cooker is an absolute bargain and a workhorse.
Cast Iron Skillet: If you don’t have a slow cooker with a stovetop friendly insert, this is my most used pan in my kitchen, heavy, keeps heat well and gives the BEST sear ever.
Chopped Clams: I always use this brand and always use pre-chopped. You can also sub baby clams but the texture would be different than a classic clam chowder.
Clam Base: I almost never buy boxes of broth because I keep the beef, chicken and vegetable version of this Better Than Bouillon. Or you can use clam juice in place of the water too if you’d like.


Ingredients
- 1/2 pound bacon diced
- 3 cans clams (6.5 ounce, not drained)
- 1 yellow onion chopped
- 4 yukon potatoes peeled and diced
- 2 stalks celery diced
- 2 cloves garlic minced
- 2 cups water *
- 1 teaspoon Kosher salt
- 1/4 teaspoon coarse ground black pepper
- 1/2 teaspoon dried thyme
- 2 cups half and half
- 2 teaspoons cornstarch
Instructions
- In a large cast iron skillet on medium high heat cook the bacon until crisp, then remove from the pan.**
- Add half of the bacon, clams, onion, potatoes, celery, garlic, water, Kosher salt, black pepper and thyme into the slow cooker and stir.
- Cook on low for 7 hours and refrigerate the remaining bacon for serving with the soup.
- In a measuring cup add the half and half with the cornstarch and whisk together.
- Add in the half and half mixture to the slow cooker and stir.
- Cook on high for 30 minutes.
- Serve with the remainder of the bacon sprinkled over the top.***
Notes
- * I add 1 tablespoon of Clam Base to the water to pump up the clam flavor in the chowder. Totally optional though.
- ** Truth? When I don't need it to look all pretty, I brown the onions and potatoes in this bacon fat before adding it to the slow cooker.
- *** You may want to heat the bacon slightly before sprinkling it on top since it will be cold from the refrigerator.
We love this soup ( and I’m not a seafood lover)! We add a little sour cream and cheddar cheese along with the bacon to serve.
I just made this chowder. It’s absolutely delicious, and I will definitely make it again. I added a little bit of corn, just for added texture. Thank you for sharing.
Made it! Left out the bacon bc the gf said bacon doesn’t belong in chowder..lol. wasnt going to argue with her.
It came out pretty good for my first attempt. I got a little impatient and slow cooked 6.5 then added the rest and went on high for 30 mins.
It could be a little bit thicker but all in all, it was a good attempt for my first ever chowder from scratch. I appreciate the help!
*I will probably add the clam base next time
Just got a slow cooker. Started with a basic beef stew and now I am going to make this chowder. Bacon makes everything better!
I did not notice how much water to put in for the initial 7 hour cook. Im good at messing things up so im going to look at this recipe again.
Thanks for the great recipe, hope it comes out great!
I don’t care for the aftertaste of corn starch, so I always thicken any gravy, stews, or soups with potato flakes. Everyone looks at me like I’m crazy, until they try it.
You omitted the water from the recipe
Reread the recipe. The water is listed there. Guess you just missed it…
