This chowder builds layers of flavor by sautéing the vegetables in smoky bacon drippings before simmering them with sweet corn and a touch of oregano. A splash of milk or half-and-half at the end makes it creamy without being heavy.
Cook the Bacon: In a large saucepan over medium heat, fry the bacon until crisp (5 to 7 minutes); drain on paper towels. Crumble and set aside.
Sauté: Pour off all but 2 tablespoons of drippings from the saucepan. To the bacon drippings, add onions, green pepper, and garlic; saute for 5 minutes.
Make the Roux: Stir in the flour and continue cooking for 2 minutes, stirring constantly.
Add Corn and Stock: Add corn kernels and chicken stock along with the salt, oregano, and freshly ground pepper. Bring to a simmer, then reduce the heat to low. Cover and simmer for 5 minutes, stirring occasionally.
Finish With Dairy and Bacon: Stir the milk and reserved bacon into the corn mixture. Cook, stirring frequently, over low heat for about 4 to 6 minutes or until mixture is hot.
