Step 1 — Sauté the Aromatics
Heat the 1½ tablespoons of vegetable oil in your large pot over medium-high heat. Add the diced onion, minced garlic, minced red bell pepper, chopped zucchini, minced jalapeño, and diced celery all at once. Sauté for 4–5 minutes, stirring frequently, until the onion becomes translucent and tender.
This sauté stage builds the flavor foundation of the entire stew. The jalapeño and red bell pepper soften slightly and their flavors meld with the garlic and onion in the hot oil creating an aromatic base that makes the finished stew taste more complex than a dump-everything approach would produce.
Oil-free option: Replace the vegetable oil with a generous splash of water or vegetable broth. Water-sautéing works well here just add small amounts as needed to prevent sticking and stir more frequently.
Step 2 — Add Potatoes, First Corn Portion, and Broth
Add the chopped potatoes, the first 2 cups of corn kernels, and all 4 cups of vegetable broth to the pot. Stir well to combine. Raise the heat and bring the pot to a full boil.
Cook uncovered for 20 minutes, or until the potatoes are completely tender when pierced with a fork. The stew should maintain a steady boil during this period adjust heat as needed to keep it actively bubbling without boiling over.
Step 3 — Make the Corn Cream Base
While the potatoes cook, add the remaining 2 cups of corn kernels, 1½ teaspoons of salt, and 2 cups of unsweetened plant-based milk to your blender. Blend on high speed until completely smooth at least 60 seconds. The result should be a thick, creamy, slightly sweet corn milk with no visible corn chunks remaining.
Once the potatoes reach full tenderness, pour this blended corn cream directly into the pot. Stir to incorporate thoroughly, bring the pot back to a boil, and cook for an additional 5 minutes. The corn cream will thicken the stew noticeably and turn the broth a beautiful golden-yellow color during this stage.
Step 4 — Partial Blend for Texture
Remove the pot from heat. Using your immersion blender, partially blend the stew — move the blender through about half of the pot's contents, leaving the other half completely intact. The goal is creamy, smooth texture in some areas while maintaining distinct pieces of corn, potato, and vegetables throughout.
The amount you blend is completely personal. Some people prefer a mostly smooth stew with occasional chunks. Others want it predominantly chunky with just enough blending to thicken the base. Start conservative you can always blend more, but you can't un-blend an over-pureed soup. Taste after each pass of the blender and stop when the texture pleases you.
Step 5 — Adjust and Serve
Taste the stew and adjust seasoning more salt, more black pepper, a squeeze of fresh lime juice if you want brightness. Ladle into bowls and garnish each serving with chopped green onion and freshly ground black pepper. Serve immediately
