Heat oil in a large skillet over medium heat. Add onion and sauté until fragrant about 3 minutes. Add potatoes and corn. Saute 2- 3 minutes, add water or stock, salt and pepper and bring to a simmer. Cover, turn the heat down to low and simmer 10 minutes, or until potatoes are fork-tender.

While the potatoes are simmering, sear the fish. Heat oil in another skillet. Season fish with salt and pepper and sear each side over medium-high heat. Lower heat and cook to your desired doneness. Set aside.

When the potatoes are fork-tender, uncover and cook off a little of the liquid. At this point, you could add a few tablespoons half and half or soy milk for a little extra creaminess (cook it for a minute or two to thicken) or simply leave it out.

Stir in half of the basil. Taste, adjust salt.

Right before serving, stir in the remaining basil, saving a little for the top. Dish up the sweet corn”chowder” and top with the seared fish and basil.
