Pour chicken broth into a large pot and bring to a boil over high heat. Add sweet corn and reduce heat to medium. Allow sweet corn to simmer 3-5 minutes until a bright yellow.
Use a tongs to remove corn from chicken broth. Reduce chicken broth heat to low. Allow corn to cool several minutes then remove kernels from cobs with a knife and set aside. Return cobs to chicken broth and allow to continue simmering on low.
Preheat oven to 400F. In a small baking dish, toss cherry tomatoes with olive oil and season with salt and pepper.
Roast cherry tomatoes at 400F 15-20 minutes until tomatoes are softened and bursting. Set aside for a moment.
In a medium skillet over medium heat, melt butter and add shallot. Saute until just tender. Add rice to skillet and stir 1-2 minutes until risotto is lightly toasted. Add garlic and saute 1 additional minute until fragrant. Pour wine into pan and cook until wine is reduced in half.
Reduce heat to medium-low and begin adding hot corn cob chicken broth (remove cobs and discard at this point to make it easier to ladle) to rice, a little bit at a time, waiting until liquid is evaporated before adding more broth.
Continue adding broth in small amounts 20-25 minutes until rice is tender and creamy. Stir in Parmesan, basil, oregano, sweet corn, and bursting tomatoes.
Season risotto with salt and pepper to taste. Serve warm and enjoy!
