Steps
Before you start
- Prep all vegetables before starting to cook—mise en place makes this much faster and smoother
- Use fresh corn when in season; frozen works beautifully too
- Jalapeño heat varies—taste one before using to gauge how much spice you want
Prep vegetables
- Dice the onion into ¼-inch pieces.
- Cut the jalapeños in half lengthwise, scoop out the seeds and white membranes with a small spoon, then dice into ¼-inch pieces.
- Mince the garlic cloves.
- Cut the potatoes into ½-inch cubes, aiming for even sizes so they cook uniformly.
- If using fresh corn, stand the cob upright on a cutting board and cut the kernels away with a sharp knife; if using frozen, measure out 4 cups and set aside.
- Arrange all prepped ingredients on a cutting board or in bowls, ready to cook.

Ready when: All vegetables are prepped, measured, and arranged
Tip: Cut potatoes into uniform ½-inch cubes so they cook evenly; uneven pieces will cook at different rates
Sauté aromatics
- Melt 2 tablespoons (30 g) unsalted butter in a large Dutch oven or heavy-bottomed pot over medium heat.
- Once the butter is foaming, add the diced onion.
- Cook for 2 to 3 minutes, stirring occasionally, until the onion is softened and translucent around the edges.
- Add the minced garlic and diced jalapeño, stir well, and cook for 1 minute more until the kitchen smells fragrant and no raw garlic scent remains.

Ready when: Onion is softened and translucent, garlic is aromatic with no raw smell
Tip: Keep heat at medium to prevent garlic from browning, which would turn it bitter
Simmer potatoes until tender
- Add the diced potatoes and 4 cups (960 ml) vegetable or chicken broth (use low-sodium to control the final salt level).
- Stir to combine, then bring to a boil over medium-high heat, about 2 minutes.
- Once boiling, reduce the heat to medium and let the soup simmer gently for 8 to 10 minutes, stirring occasionally.
- The potatoes should be fork-tender but still holding their shape, not mushy.

Ready when: Potatoes are easily pierced with a fork but don't fall apart, broth simmers gently
Tip: Simmer gently rather than boiling vigorously, or the potatoes may break apart into the soup
Add corn and simmer
- Stir in the 4 cups (575 g) corn kernels.
- Adjust the heat to maintain a gentle simmer over medium heat and cook for 8 minutes, stirring occasionally, until the corn is tender and heated through.
- The potatoes should now be completely fork-tender.

Ready when: Corn kernels are tender and plump, potatoes are soft throughout
Tip: If using very old frozen corn or canned corn, reduce simmering time to 4 to 5 minutes to prevent mushiness
Add cream and season
- Reduce the heat to medium-low.
- Stir in 1 cup (240 ml) heavy cream with a wooden spoon, stirring gently to combine.
- Simmer for 1 to 2 minutes just to heat the cream through—you should see small wisps of steam but not a rolling boil.
- Season with kosher salt and freshly ground black pepper to taste.
- Start with ½ teaspoon salt and ¼ teaspoon pepper, taste, and adjust.
- The soup should taste savory with a gentle warmth from the jalapeños, balanced by the sweetness of corn and earthiness of potatoes.

Ready when: Cream is heated through (small steam wisps visible), flavors are balanced and well-seasoned
Tip: Avoid boiling after adding cream, as high heat can cause it to curdle or separate
Serve
- Ladle the hot chowder into bowls.
- Top each serving with a small handful of fresh chopped cilantro and a squeeze of fresh lime juice.
- Serve immediately while hot.

Good to know
Tips
- For a creamier, thicker texture without extra cream, use an immersion blender to purée about 1 cup of the finished soup right in the pot, then stir it back in for added body
- Potatoes vary in cooking time depending on variety and size—check tenderness with a fork starting at the 7-minute mark rather than following time exactly
- This soup thickens slightly as it cools due to starch release from potatoes; add extra broth when reheating to reach your desired consistency
- Prepare all vegetables before cooking (mise en place). This keeps the process smooth and prevents scrambling to chop while something simmers
Make ahead
The soup can be made up to 2 days ahead. Cool completely, cover, and refrigerate. Reheat gently over medium-low heat, stirring occasionally. If the soup is too thick after refrigerating, add a splash of broth or milk when reheating.
Storage & reheating
Room temperature: up to 2 hours (cover to keep clean). Refrigerator: up to 3 days in an airtight container. Freezer: up to 3 months in airtight containers (leave ½-inch headspace); thaw overnight in the fridge and reheat gently over medium-low heat, stirring occasionally.
Substitutions
- corn kernels, fresh or frozen → 4 cups (500 g) diced zucchini or summer squash. Reduces cooking time for the corn step to 5 minutes; the zucchini should be just tender
- heavy cream → 1 cup (240 ml) half-and-half, whole milk, or a mixture of ¾ cup (180 ml) milk and 2 tablespoons (30 g) butter. Creates a lighter, less rich soup; stir the milk mixture gently to avoid curdling
- fresh jalapeño peppers → 2 serranos for more heat, 2 poblanos for milder and richer flavor, or omit and add ½ teaspoon ground cumin for earthiness. Customizes the heat level to your preference
- vegetable or chicken broth, low-sodium → 4 cups (960 ml) chicken broth, or 4 cups (960 ml) water plus 1 vegetable bouillon cube. Chicken broth adds richness; bouillon is convenient when fresh broth isn't available
