Ingredients (Serves 4)
- 1 tablespoon olive oil (15 ml)
- 1 medium yellow onion, diced (about 150 g)
- 2 celery stalks, diced (about 100 g)
- 3 garlic cloves, minced (about 9 g)
- 2 medium zucchini, diced (about 450 g)
- 2 cups corn kernels, fresh or frozen (300 g)
- 2 medium Yukon Gold potatoes, diced small (about 340 g)
- 4 cups vegetable broth (960 ml)
- 1 teaspoon dried thyme (1 g) or 1 tablespoon fresh thyme (3 g)
- 1 cup whole milk (240 ml)
- 1 1/2 cups shredded cheddar cheese (170 g)
- Salt and black pepper, to taste
Step-by-Step Instructions
1. Sauté the Aromatics
Warm the olive oil in a large soup pot over medium heat. Add the onion and celery. Cook for 5 minutes, stirring often, until the onion looks glossy and soft. Add the garlic and cook for 30 seconds, just until your kitchen smells warm and savory.
2. Add the Vegetables and Broth
Stir in the zucchini, corn, potatoes, vegetable broth, thyme, 1 teaspoon salt, and a few grinds of black pepper. Scrape the bottom of the pot so the sweet onion bits mix into the broth.
3. Simmer Until Tender
Bring the soup to a gentle boil, then lower the heat to a steady simmer. Cook for 15 to 20 minutes, until the potatoes break easily when pressed with a spoon. The zucchini should look tender but still bright green, and the broth should smell herby and sweet from the corn.
4. Partially Blend the Chowder
Use an immersion blender to blend part of the soup right in the pot. Stop while plenty of corn, zucchini, and potato chunks remain. If using a regular blender, transfer about 2 cups of soup, blend until smooth, then stir it back into the pot.
5. Stir in the Milk and Cheddar
Turn the heat to low. Stir in the milk, then add the cheddar a handful at a time. Stir slowly until the cheese melts into the broth and the chowder looks creamy and pale golden. Do not let it boil after adding the milk and cheese.
6. Taste and Serve
Taste the chowder and adjust with more salt, pepper, or thyme. Serve hot, with extra cheddar or cracked black pepper on top if you like. The soup should be creamy, chunky, sweet, savory, and spoonable.
Expert Troubleshooting and FAQs
Why did my chowder turn grainy?
The heat was likely too high after adding the milk and cheese. Keep the pot on low heat and stir the cheddar in slowly. Boiling can make dairy separate.
Can I use frozen zucchini?
Yes, but fresh zucchini gives the best texture. If using frozen zucchini, add it straight from the freezer and simmer only until tender. It may release extra water, so blend a little more potato to thicken the soup.
How do I make the chowder thicker?
Blend a larger portion of the soup, especially the potatoes. You can also simmer it uncovered for a few extra minutes before adding the milk and cheese.
Can I make this chowder ahead of time?
Yes. Cook the soup through the blending step, then cool and refrigerate it. When ready to serve, warm it gently, then stir in the milk and cheddar so the texture stays smooth.
What can I use instead of cheddar?
Monterey Jack, Colby, or a mild white cheddar all melt well. For the smoothest finish, shred the cheese yourself because bagged shredded cheese can melt less evenly.
