In a 10-inch cast-iron skillet, heat oil over medium-high heat. Add zucchini and shallot; cook, stirring frequently, until crisp-tender, about 4 minutes. Stir in corn, pecans, garlic, cold butter, salt, black pepper, and red pepper; cook until butter is melted and vegetables are tender, about 2 minutes. Stir in basil just before serving. Garnish with basil, if desired.
