What is Manhattan Clam Chowder?
Manhattan clam chowder just so happens to have a pretty cool history. Due to the large Italian population in New York and Rhode Island during the 1800s, it was inevitable that the introduction of tomatoes and tomato-based clam chowders would become popular.
Contrary to New England clam chowder, which has a creamy, milky-white base, Manhattan chowder is tomatoey, brothy, and clear. This red chowder gets its chowder base from chicken broth, clam juice, and tomatoes (of course).
Recipe Ingredients
- Clams: You’ll need at least two 10-ounce cans of whole clams for this crock pot recipe.
- Clam Juice: You can find bottled clam juice in your local grocery store.
- Tomatoes: Canned diced tomatoes and crushed tomatoes are both added to help create the tomato chowder base and add the tomato flavor.
- Potatoes: To help make sure the potatoes are tender by the end of cooking time, they’ll need to be diced.
- Chicken Broth: I think this tastes best for making this type of chowder.
- Vegetables: Corn, carrots, onion, and celery are all chopped and tossed into the crockpot.
- Seasonings: Freshly ground black pepper, kosher salt, old bay seasoning, fresh thyme, and Tobasco sauce adds the right amount of flavor.
Step-by-Step Directions
Step One – In a slow cooker, combine the celery, carrots, onion, corn, potatoes, diced tomatoes, crushed tomatoes, and whole clams.
Step Two – Then add chicken stock, Tabasco sauce, old bay seasoning, salt, pepper, thyme leaves, and clam juice.
Step Three – Stir everything together with a slotted spoon to combine well.
Step Four – Cover and cook on LOW heat for 6-8 hours or HIGH for 4 hours, or until the vegetables are tender. Ladle the chowder into bowls and top with your choice of optional toppings. Enjoy!
How to serve
- In addition to serving it as-is in bowls, you can add a variety of toppings such as cooked bacon crumbled, chopped fresh parsley, red pepper flakes, an extra dash of hot sauce, and other fresh herbs.
- This soup also pairs well with other cooked vegetables (roasted or steamed) and Italian bread, sourdough bread and butter. And, of course saltine crackers or oyster crackers.
Recipe FAQs and Variations
Sure. Although I’ve never tried it with any other kind, you could try diced baby red potatoes.
If you live near a fish market, you can always pick up some fresh clams or use whole baby clams (or two cans chopped clams).
I suggest letting them thaw overnight to make sure they cook thoroughly.
Keep in mind the biggest differences between the two soup recipes. The clam broth with the Manhattan is made with tomatoes whereas the England chowder calls for broth, flour, and whipping cream for a creamy clam chowder. In addition to these two, there’s also Rhode Island clam chowder made with salt pork and dry white wine.
Leftovers can be stored in the refrigerator for up to 3 days in an airtight container. Reheat on the stove-top or in the microwave. It is not recommended to freeze the chowder as the potatoes and vegetables will become mushy when thawed.
Other vegetables that can be added to the recipe are bell peppers, zucchini, or green beans.
Vegetable broth or fish stock can be used in place of the chicken stock. You can also add shrimp, bay scallops or white fish to this recipe.
This recipe can be made on the stove-top as well, add all ingredients to a large stock pot, cover and cook on medium heat for 30-45 minutes until the vegetables are tender.

Excellent Manhattan Clam Chowder recipe, will make again! But will only do 1/2 tbsp. vs 1 tbsp. of Old Bay Seasoning. It was too spicy for us. Thank you!
Thank you for sharing this recipe. I love Manhattan style clam chowder, but you don’t see many recipes for it. I will definitely try it.
Drained the whole clams and the chowder was still way too clammy with the 8oz of juice. Had to throw it out.
In the ingredients it says the whole clams should be drained but in the instructions it says to add the whole clams with the juice.
I hate it when I spend the time and money making a recipe and it doesnt turn out, but I believe it’s referring to the bottled clam juice, not the juice the clams are packed in.
