To make a tortellini minestrone soup recipe, you'll first need to gather your ingredients. To do this, first gather the following ingredients: 1 1/2 cups drained and rinsed fettuccine alfredo, 2 tablespoons olive oil, 1 teaspoon kosher salt, 1/4 teaspoon pepper, 1/2 cup chopped thyme sprigs, and 1 tablespoon dried or fresh oregano. Cook the pasta in salted water until al dente, about 5 minutes. Drain and set aside. In the same pot, cook the remaining ingredients over medium-high heat, stirring occasionally, until the vegetables are tender and the broth is reduced by half. Add the tarragon and cook, tossing, for 1 minute. Season with salt and pepper to taste. Serve immediately.
