Sweet Corn Risotto with Sautéed Shrimp

In a medium saucepan, bring chicken stock to a simmer. In a large, deep skillet, heat 1 tablespoon olive oil over medium-high heat. Add onion and sauté until beginning to soften, 4 minutes. Add rice and cook, stirring constantly, 1 minute. Add 1/2 cup white wine and simmer until evaporated, 2 to 3 minutes. Reduce heat to medium. Add about 1/2 cup more stock and simmer, stirring occasionally, until absorbed. Continue adding stock by the 1/2 cup, stirring and letting it absorb, until stock is gone, 15 to 20 minutes. Remove from heat and stir in corn, butter, Parmesan, and parsley. Season with salt and pepper and transfer to a large bowl. Add remaining 2 tablespoons olive oil to skillet and heat over medium-high heat. Add garlic, shallot, and red pepper flakes, and cook until fragrant, 1 to 2 minutes. Add shrimp and cook until pink and beginning to brown, 3 to 4 minutes. Add remaining 1/4 cup wine and let simmer until evaporated, 2 minutes. Remove from heat, season with salt and pepper, and stir in basil. Add risotto back to skillet, stirring to combine with shrimp. Garnish with basil and serve.
