Preheat the oven to 375°F (190°C).
In a large 9×13-inch baking dish, add the grape tomatoes and minced garlic; drizzle with the olive oil and toss to coat.
Place the package of garlic herb Boursin cheese in the center of the dish among the tomatoes and bake for 10 minutes, until the cheese softens and the tomatoes begin to burst.
Remove the dish from the oven and stir in the uncooked orzo, chicken or vegetable broth, heavy cream, and salt, mashing the softened tomatoes and mixing the softened Boursin into the liquid.
Return the dish to the oven and bake for 30 minutes. After 30 minutes, remove and stir; if the orzo is not tender, bake up to an additional 10 minutes until done.
When the orzo is cooked and creamy, remove from the oven, stir once more, then sprinkle with the chopped basil and serve immediately.
