Crockpot Clam Chowder is a hearty, comforting soup made simple by slow cooking. The gentle simmer allows flavors to meld into a rich, creamy broth studded with tender clams and bite-sized potatoes. Each spoonful offers a satisfying balance of savory, creamy, and a touch of briny saltiness. Serve it with Classic Potato Rolls and a light vegetable salad for a cozy meal. This easy, classic chowder warms the soul and satisfies the taste buds.
Ingredients to Have on Hand
The ingredient list is straightforward and accessible. With basic pantry staples and a slow cooker, you can make a chowder that’s better than many restaurant versions.
- canned clams (minced and whole)
- potatoes (Russet, Yukon Gold or red)
- celery
- onion
- half and half
- butter
- flour
- chicken bouillon
See the recipe below for exact measurements and a full ingredient list.
Step-by-Step Instructions for the Broth
Scratch-made clam chowder is surprisingly simple when you use a slow cooker. The long, low heat builds deep flavor with minimal hands-on time.
1. Rinse and peel potatoes until you have about 2 cups diced (about 2 large Russets or 3 small).
2. Rinse and chop 1 cup celery (about 4 stalks).
3. Dice onion to equal ¾ cup.
4. Drain the canned minced and whole clams, reserving the clam juice in a 2-cup measuring cup. If needed, add a few tablespoons of water to reach 2 cups total liquid.
5. Place the drained clams in a sealed container and refrigerate until the final step — canned clams only need to be warmed through at the end.
6. Place the potatoes, celery, and onion in the bottom of the Crockpot or slow cooker.
7. Add the chicken bouillon and the 2 cups of reserved clam juice.
8. Cover and cook on low for 4–6 hours. The vegetables will soften and infuse the broth with flavor.
Two-Step Cooking Process
This recipe uses a two-step method: the slow cooker builds the broth and softens the vegetables, and a quick stovetop white sauce finishes the chowder. That combination gives a smooth, creamy texture and well-developed flavor.
Cook the broth portion on low for 4–6 hours. Be careful not to exceed 6 hours on low or the potatoes can become overly soft and start to break down.
When the vegetables and clam juice are cooked through, prepare the white sauce on the stove — it only takes a few minutes.
How to Make the White Sauce
After the slow cooker finishes, switch it to warm and make the white sauce on the stovetop. The sauce thickens and adds creaminess without losing the clam flavor.
Steps for the white sauce:
- Melt ¼ cup butter in a medium saucepan over medium heat. Whisk in ¼ cup flour to form a roux.
- Cook and whisk for about a minute, keeping the heat moderate so the roux doesn’t darken.
- Slowly whisk in the half and half and simmer until the sauce thickens to a creamy consistency.
Once the white sauce is smooth, add it to the slow cooker along with the reserved clams, stir, and let the chowder warm on the “warm” setting for about 10 minutes before serving so the clams heat through without overcooking.
Stovetop Option
If you prefer, this chowder adapts easily to the stovetop and is ready in about an hour. The method is the same: cook the vegetables in clam juice, make a white sauce, combine, and warm the clams at the end.
Step-by-Step for Stovetop Cooking
- Drain the clam juice into a large saucepan and reserve the clams.
- Add diced potatoes, onion, celery, chicken bouillon, and just enough water to cover the vegetables.
- Simmer about 20 minutes until potatoes and celery are tender.
- In a separate pan, melt butter, whisk in flour for about a minute, then add half and half and whisk until thick and creamy.
- Season the white sauce with salt and pepper, pour into the pan with the cooked vegetables and stir to combine.
- Add the reserved clams and warm gently over medium-low for about 10 minutes before serving.
Size of the Slow Cooker
A large 7-quart oblong Crockpot works well because the vegetables spread out and cook evenly, but any slow cooker that holds at least 4 quarts will work fine.
Boston Clam Chowder
This recipe is Boston (New England) style clam chowder, meaning it uses dairy — half and half in this case — to create a creamy white chowder. The alternative, Manhattan clam chowder, is tomato-based and thinner. Both styles are delicious; this version is classic, creamy comfort food.
Why You’ll Love This Recipe
Slow-cooking the potatoes, celery, and onion in clam juice brings out rich, concentrated flavor that you can’t get with quick methods. The Crockpot makes it easy: minimal prep, hands-off cooking, and a deeply flavorful chowder when you return to finish it with a quick white sauce.
Clam Chowder Toppings
Top your chowder to taste. A single garnish or a combination adds texture and flavor:
- cooked, diced bacon
- oyster crackers or saltine crackers
- dried or fresh parsley
- diced green onion
The Inspiration
This recipe was shared by a family friend and longtime cook, whose stovetop chowder inspired a slightly adapted Crockpot version. The change moves part of the process to the slow cooker for easier, hands-off preparation while preserving the classic flavor.
Storage
Store leftover chowder in a covered container in the refrigerator and enjoy within 3 days for best flavor. Chowder can also be frozen for longer storage.
Top Tips and FAQ
Yes. Cool the chowder, transfer to a freezer-safe container, and freeze for up to three months. Thaw in the refrigerator overnight and reheat gently on the stove over low heat. The chowder may thicken when reheated — thin with a splash of milk or water if needed.
For an extra-thick chowder, increase the butter and flour in the white sauce to ½ cup each with one quart of half and half. Alternatively, mix 2 tablespoons cornstarch with 2 tablespoons water and stir into the finished chowder to thicken.
Yes. Prepare and cook fresh clams, remove the meat from shells, and use about 1½–2 cups of clam meat (roughly 2½ pounds of whole clams). If using fresh clams, add two 8-ounce jars of clam juice to the slow cooker for adequate liquid and flavor.
Food safety
Keep the following in mind:
- Cook foods to at least 165 °F (74 °C) when appropriate.
- Avoid cross-contamination between raw and cooked foods.
- Don’t leave perishable food at room temperature for extended periods.
- Use good ventilation when cooking on a gas stove.
