Servings: 6 | Prep time: 10 minutes | Cook time: 6–7 hours (LOW) or 3–4 hours (HIGH) plus 20–30 minutes | Total time: Varies

There are some soups that just feel like a warm hug in a bowl. This Slow Cooker 4-Ingredient Corn Chowder is one of them. Creamy, sweet, and savory, with tender potatoes and pops of sweet corn in every spoonful — it’s the kind of soup that makes a cold day feel cozy and a busy weeknight manageable.

With just four core ingredients and almost no hands-on time, this chowder is almost embarrassingly easy to make. Potatoes, corn, broth, and cream — that’s all it takes to create a rich, velvety soup that tastes like it simmered on the stove for hours.

The slow cooker does all the work. The potatoes become tender and release their starch, naturally thickening the broth. The corn adds sweetness and texture. And the heavy cream transforms everything into a luscious, restaurant-quality chowder.

Serve it with crusty bread or oyster crackers, and you have a complete meal that will have everyone asking for seconds.

Ingredients

Peeled and diced russet potatoes (about 3 medium potatoes, cut into ½-inch cubes) – 4 cups
Frozen corn kernels (or canned corn, drained) – 3 cups
Chicken broth or vegetable broth – 4 cups
Heavy cream (or half-and-half for a lighter version) – 2 cups
Freshly ground black pepper, for serving (optional garnish) – To taste

Ingredient Notes

What kind of potatoes? Russet potatoes are starchy and break down slightly, naturally thickening the chowder. Yukon Gold potatoes hold their shape better and have a naturally buttery flavor. Both work — choose based on your texture preference.

What kind of corn? Frozen corn kernels are convenient and sweet. Canned corn (drained) works too. Fresh corn cut off the cob is delicious when in season. Avoid creamed corn — it will make the chowder too thick and sweet.

What kind of broth? Chicken broth adds savory depth. Vegetable broth keeps the chowder vegetarian. Low-sodium broth is recommended so you can control the salt level.

What kind of cream? Heavy cream creates the richest, velvety chowder. Half-and-half will work but will result in a thinner, less creamy soup. Do not use milk — it may curdle and won’t create the same texture.

Do I need to add salt? The broth usually has enough salt. Taste the chowder before adding any extra salt. A pinch of salt at the end can help brighten the flavors.

Do I need to add any other seasonings? This recipe is intentionally simple. A little black pepper at the end is lovely. Some people like to add a pinch of thyme, smoked paprika, or a dash of hot sauce.

Step-by-Step Instructions

Step 1: Layer the Potatoes and Corn

Add the 4 cups of diced potatoes to the bottom of a 4- to 6-quart slow cooker, spreading them out in an even layer.

Pour the 3 cups of corn over the potatoes.

Step 2: Add the Broth

Pour 4 cups of chicken or vegetable brothover the potatoes and corn. Gently stir to combine, making sure most of the potatoes are submerged in liquid.

Step 3: Cover and Cook

Cover the slow cooker with the lid. Cook on:

LOW for 6 to 7 hours, or
HIGH for 3 to 4 hours

The chowder is ready when the potatoes are very tender and easily pierced with a fork.

Step 4: Mash to Thicken

Once the potatoes are soft, use a potato masher or the back of a spoon to lightly mash some of the potatoes and corn right in the slow cooker. This will help thicken the chowder while still leaving plenty of chunks.

Step 5: Add the Cream

Stir in 2 cups of heavy cream. Cover and cook on LOW for another 20 to 30 minutes, just until the chowder is heated through and slightly thickened.

Important: Do not let it boil, or the cream can separate. Keep it at a gentle simmer or warm setting.

Step 6: Season and Serve

Taste and adjust seasoning if needed (the broth usually has enough salt, so I typically just add pepper at the table).

Ladle the creamy corn chowder into bowls and garnish with freshly cracked black pepper. Serve warm straight from the slow cooker.

Variations & Tips

Make It with Bacon

Cook 6 slices of bacon until crispy, crumble, and sprinkle on top before serving. For even more flavor, cook the bacon in a skillet, then add the rendered fat (1 tablespoon) to the slow cooker along with the broth.

Make It with Cheddar

Stir in 1 cup of shredded sharp cheddar cheese along with the heavy cream. The cheese melts into the chowder, creating a cheddar-corn chowder.

Make It Spicy

Add ½ teaspoon of cayenne pepper or red pepper flakes
Add 1 (4 oz) can of diced green chilesalong with the broth
Top with sliced jalapeños or hot sauce

Add Onion and Garlic

Add 1 small diced onion and 2 cloves of minced garlic along with the potatoes. Sauté them first for deeper flavor, or add them raw.

Add Carrots or Celery

Add 1 cup of diced carrots or 1 cup of diced celery along with the potatoes. They add color, texture, and flavor.

Add Fresh Herbs

Add 1 teaspoon of dried thyme or 1 tablespoon of fresh parsley at the end. Thyme is a classic pairing with corn chowder.

Make It Lighter

Use half-and-half instead of heavy cream
Use low-fat milk mixed with 1 tablespoon of cornstarch (to thicken)
Use vegetable broth instead of chicken broth

Make It Dairy-Free

Use full-fat coconut milk instead of heavy cream (adds a slight coconut flavor)
Use cashew cream (soaked cashews blended with water)
Omit the cream entirely — the chowder will be thinner but still delicious

Make It Gluten-Free

This recipe is naturally gluten-free — just check that your broth is gluten-free (most are).

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 5 days. The chowder will thicken as it cools — that’s normal.

Reheating:

Microwave: 1–2 minutes per serving. Add a splash of milk or broth if it’s too thick.
Stovetop: Warm over medium-low heat, stirring frequently. Add a splash of broth or milk to thin if needed.
Slow cooker: Warm on LOW for 30–45 minutes.

Freezing: Cream-based soups can separate when frozen. If you plan to freeze this chowder, consider freezing before adding the cream. Add fresh cream when reheating. If you freeze the finished chowder, thaw overnight in the refrigerator and reheat gently, stirring well.

Frequently Asked Questions (FAQs)

Can I use canned corn instead of frozen?

Yes. Use 3 cups of canned corn, drained. Canned corn is already cooked, so it may be slightly softer than frozen corn.

Can I use fresh corn?

Yes. Use about 4–5 ears of fresh corn. Cut the kernels off the cob. Fresh corn is sweetest in the summer.

Why do I need to mash some of the potatoes?

Mashing some of the potatoes releases their starch, which naturally thickens the chowder. It also creates a creamier texture while still leaving plenty of potato chunks.

Why do I add the cream at the end?

Adding cream at the beginning can cause it to curdle or separate during the long cooking time. Adding it at the end ensures a smooth, creamy chowder.

Why is my chowder thin?

A few possibilities:

You didn’t mash enough potatoes (the starch thickens the chowder)
You used half-and-half instead of heavy cream (thinner)
You added too much broth

To fix: make a slurry with 1 tablespoon of cornstarch and 2 tablespoons of cold water, stir it in, and cook on HIGH for 10–15 minutes until thickened.

Why is my chowder too thick?

Stir in a splash of broth or milk until it reaches your desired consistency. Do this just before serving.

What should I serve with this chowder?

Crusty bread or dinner rolls – For sopping up every drop
Oyster crackers or saltines – Classic soup accompaniment
A simple green salad – With a tangy vinaigrette

Why This Recipe Works

This four-ingredient chowder is a perfect example of “less is more.” Here’s why it works so well:

Russet potatoes are starchy. As they cook, they release starch into the broth, naturally thickening the chowder without needing flour or cornstarch.

Corn adds sweetness, texture, and pops of bright flavor. Frozen corn is picked at peak ripeness and flash-frozen, so it’s consistently sweet year-round.

Chicken or vegetable broth provides a savory base. The broth infuses the potatoes and corn with flavor as they cook.

Heavy cream adds richness and creates that luscious, velvety texture that makes chowder so satisfying.

Mashing some of the potatoes at the end releases more starch and creates a creamier consistency while still leaving plenty of chunks.

The result is a chowder that’s creamy, sweet, savory, and deeply satisfying — with almost no effort at all.

The slow cooker does all the work. The potatoes become tender and thicken the broth. The corn adds sweetness. The cream makes it luxurious. And the whole thing comes together with almost no effort.
