This Creamy Lemon-Dill Sauce Is So Good, I've Already Made It Twice This Month

Place garlic, lemon zest, 1 1/4 cups heavy cream, 1 1/4 cups low-sodium vegetable or chicken broth, 1/2 teaspoon kosher salt, and 1/4 teaspoon freshly ground black pepper in a large skillet. Bring to a simmer over medium heat, stirring to combine. Add 20 ounces refrigerated or frozen cheese tortellini (it will be halfway submerged in the sauce). Cook, stirring frequently to prevent the tortellini from sticking, until tender and warmed through, about 6 minutes for refrigerated tortellini or 10 minutes for frozen tortellini.
