What Ingredients You Will Need

This summer corn and zucchini chowder keeps things simple but delivers big flavor. I love that the ingredients are mostly pantry staples or easy farmer’s market finds. Here’s everything you’ll need:

For the Chowder Base:
- Unsalted butter (2 tbsp / 28g) – for sautéing, adds richness
- Olive oil (1 tbsp / 15ml) – helps prevent the butter from burning
- Yellow onion (1 large, diced / about 1 cup / 150g) – sweet foundation
- Garlic cloves (3, minced) – fresh or jarred, for savory kick
- Celery stalks (2, diced / about 1/2 cup / 70g) – classic chowder flavor
- Carrot (1 medium, diced / about 1/2 cup / 70g) – adds subtle sweetness
Veggies & Creaminess:
- Fresh corn kernels (from 4 ears, about 2 cups / 320g; or use frozen)
- Zucchini (2 medium, diced / about 3 cups / 400g)
- Yukon Gold potatoes (2 medium, diced / about 2 cups / 300g) – for thickening
- Vegetable broth (4 cups / 960ml) – use your favorite brand for best flavor
- Whole milk (1 cup / 240ml) – for creaminess (use oat or almond milk for dairy-free)
- Heavy cream (1/2 cup / 120ml) – optional, for extra richness (skip or use coconut cream for vegan version)
- Shredded cheddar cheese (3/4 cup / 75g) – sharp or mild, for flavor depth (optional)
Seasonings & Finishing Touches:
- Salt (1 1/2 tsp / 7g) – taste and adjust as needed
- Black pepper (1/2 tsp / 2g) – freshly ground, if possible
- Smoked paprika (1/2 tsp / 2g) – optional, for subtle smokiness
- Fresh thyme (1 tbsp, leaves only) – or 1 tsp dried thyme
- Fresh parsley (2 tbsp, chopped) – for garnish
- Lemon (1, juiced) – to brighten up the flavors at the end
Optional Toppings:
- Crusty bread or oyster crackers
- More shredded cheddar
- Sliced green onions

If you need gluten-free, make sure your broth is certified safe. For vegan, swap dairy for plant-based milk and cheese. I’m partial to using local sweet corn in peak summer, but frozen works well in a pinch. And if you’re low on zucchini, yellow squash is a great stand-in!

Equipment Needed

You don’t need a fancy kitchen setup for this summer corn and zucchini chowder, promise. Here’s what will make things easy:

Large soup pot or Dutch oven: Heavy-bottomed is best for even heat. I use my trusty enameled Dutch oven; a big stockpot works too.
Sharp chef’s knife: For chopping veggies. If you don’t have one, a sturdy paring knife will do (just watch your fingers!).
Cutting board: I prefer a big wooden board, but plastic is fine—just make sure it’s clean.
Measuring cups and spoons: For accuracy (and fewer surprises!).
Wooden spoon or silicone spatula: For stirring and scraping up those tasty browned bits.
Immersion blender or regular blender: Optional, for blending part of the chowder for creaminess. If you don’t have either, a potato masher can work in a pinch.
Ladle: For serving up big, comforting bowls.
Soup bowls: Wide, deep bowls show off the chowder’s color and texture.

If you’re just starting out, don’t stress—this recipe is forgiving. I once made it with just a saucepan and a fork for mashing, and it still turned out tasty. For maintenance, keep your immersion blender blades sharp by rinsing after each use. A budget-friendly pot from the local market will do just fine—good chowder doesn’t care how much your cookware costs!

Preparation Method

Prep the veggies: Wash and dice the onion, celery, carrot, zucchini, and potatoes into small, even pieces (about 1/2-inch cubes). Slice corn kernels off the cob if using fresh.

(Tip: Use a large bowl to catch flying kernels!)

Time: 10 minutes
Sauté aromatics: In your large soup pot over medium heat, melt 2 tbsp butter with 1 tbsp olive oil. Add diced onion, celery, and carrot. Cook, stirring occasionally, until veggies are softened and onions look translucent, about 5 minutes.

(Smells amazing at this stage!)
Add garlic and spices: Stir in minced garlic, 1/2 tsp smoked paprika, and 1 tbsp thyme leaves. Cook for 1 minute, just until fragrant.

(Don’t let the garlic brown—it goes bitter fast.)
Add corn, zucchini, and potatoes: Toss in corn kernels, zucchini, and diced potatoes. Sprinkle with 1 1/2 tsp salt and 1/2 tsp black pepper. Stir to coat the veggies in the aromatic oil.

Time: 2 minutes
Pour in broth: Add 4 cups vegetable broth. Increase heat to high and bring to a gentle boil. Once boiling, reduce heat to medium-low and let simmer, uncovered, for 15–20 minutes, until potatoes are fork-tender.

(If the liquid evaporates too quickly, add a splash more broth.)
Blend for creaminess: Using an immersion blender, blend about 1/3 of the soup directly in the pot. If using a regular blender, carefully ladle out 2 cups of the chowder, blend until smooth, then return to the pot.

(Don’t over-blend, or you’ll lose those tasty veggie chunks!)
Stir in dairy: Pour in 1 cup milk and 1/2 cup heavy cream. Add 3/4 cup shredded cheddar cheese, stirring until melted and smooth. Simmer on low for 5 minutes more.

(If you’re dairy-free, use oat milk and skip the cheese. The chowder will still be creamy.)
Finish and taste: Squeeze in juice from 1 lemon. Stir in chopped parsley. Taste and adjust seasoning as needed—add more salt, pepper, or paprika to suit your mood.

Time: 2 minutes
Serve hot: Ladle chowder into bowls. Top with extra parsley, cheddar, or crackers if desired.

(Chowder is best hot, but leftovers reheat well!)

Troubleshooting: If chowder is too thick, add extra broth or milk. Too thin? Simmer uncovered a few more minutes. If flavors seem flat, a pinch more salt and a squeeze of lemon usually fix it!

Personal tip: I always prep veggies ahead in the morning—makes dinnertime super easy. And don’t worry if your chowder looks “rustic”—that’s part of the charm!

Cooking Tips & Techniques

I’ve made this summer corn and zucchini chowder so many times, I could almost do it blindfolded (but don’t try that at home!). Here are my best tips for getting it just right:

Sauté veggies slowly: Don’t rush the aromatics. Let the onions, celery, and carrot soften gently—they’re building flavor for the whole chowder.
Layer your seasoning: Salt goes in early to draw out veggie moisture, but always taste before serving. A last-minute sprinkle of smoked paprika can completely wake up the flavors.
Don’t over-blend: Chowder is supposed to have texture! I learned that the hard way after turning a batch into baby food. Just blend enough to get creaminess, then leave some chunky bits.
Use fresh corn if possible: It’s sweeter and juicier, but frozen works in a pinch. If the corn isn’t peak season, add a pinch of sugar to mimic that fresh sweetness.
Adjust for dairy-free diets: Oat milk and coconut cream both work well. Skip the cheese, or use a vegan shredded alternative. The soup will still be creamy and satisfying!
Multitasking: While the chowder simmers, chop your fresh herbs, slice bread, or whip up a simple green salad. Makes dinner feel more special, with zero extra stress.
Consistency fix: If the chowder is too thick, add more broth or milk. Too thin? Simmer uncovered for a few extra minutes.

I’ve burned the garlic once or twice, and yeah, it’s not great. If that happens, just scoop out the burnt bits and move on—the chowder will forgive you! The more you make this recipe, the easier it gets to judge the best timing and taste.

For perfect texture, I always use Yukon Gold potatoes—they break down just enough to thicken the chowder but still keep their shape. And don’t skip the lemon juice at the end; it’s the secret to a bright, fresh finish!

Variations & Adaptations

One of the joys of summer corn and zucchini chowder is how flexible it is. Here are some fun twists you can try:

Vegan version: Replace milk and cream with unsweetened oat or almond milk, skip the cheese (or use vegan shredded cheese). Coconut cream adds extra richness.
Gluten-free: This recipe is naturally gluten-free, just double-check your vegetable broth label.
Spicy Southwest Chowder: Add 1 minced jalapeño with the garlic, and stir in 1/2 cup canned fire-roasted green chilies. Top bowls with diced avocado and cilantro.
Seasonal swaps: If zucchini isn’t available, yellow squash is a great substitute. In late summer, fresh bell peppers or a handful of cherry tomatoes work beautifully.
Protein boost: For a heartier meal, add a can of drained white beans with the potatoes. I’ve tried it with chickpeas—surprisingly delicious!
Cheesy chowder: Use smoked gouda instead of cheddar for a deeper flavor, or stir in a little cream cheese for extra creaminess.
Personal favorite: I sometimes toss in a handful of baby spinach in the last 2 minutes for color and nutrition. It wilts down perfectly and adds a nice twist.

Allergen concerns? Skip the dairy or use lactose-free products. You can use vegan cheese for dairy allergies, and coconut cream for nut allergies. Feel free to experiment—the base recipe is forgiving!

Serving & Storage Suggestions

This summer corn and zucchini chowder is best served piping hot, straight from the pot. I love ladling it into wide bowls so you get plenty of chunky veggies in every bite. A sprinkle of fresh parsley or extra cheddar cheese on top makes it look as good as it tastes.

Pair it with crusty sourdough bread, garlic toast, or a simple green salad for a complete meal. For drinks, chilled white wine or iced herbal tea are refreshing choices. If you’re hosting brunch, this chowder fits right in with quiche or fruit salad.

For leftovers, let the chowder cool completely before transferring to an airtight container. It keeps in the refrigerator for up to 4 days. To freeze, portion into freezer-safe bags or containers—leave a little room for expansion. Thaw overnight in the fridge, then reheat gently on the stovetop, adding a splash of broth to loosen if needed.

Over time, the flavors deepen and mellow, so the chowder tastes even better the next day. I always make a double batch for easy lunches during the week!
