Bring a large pot of salted water to a boil. Add the 10 ounces of fettuccine and cook according to package instructions until al dente. During the last 3 minutes of cooking, add the 2 cups of chopped broccoli to the pot. Drain the pasta and broccoli in a colander and set aside.
In a large skillet over medium heat, melt the 2 tablespoons of unsalted butter. Once melted, add the 1-1/2 teaspoons of minced garlic and sauté for about 1 minute, or until fragrant.
Pour in the 3/4 cup of heavy cream and 1/4 cup of chicken stock, stirring to combine. Allow the mixture to simmer for 2-3 minutes, letting it thicken slightly.
Stir in the 1/4 cup of basil pesto and 1/2 cup of freshly grated Parmesan cheese. Mix until the cheese has melted and the sauce is creamy. Season with salt and pepper to taste.
Add the drained fettuccine and broccoli to the skillet, tossing gently to coat everything evenly with the creamy pesto sauce. Finally, fold in the 3/4 cup of drained sun-dried tomatoes for added flavor and color.
Serve your Creamy Pesto Pasta immediately, garnished with additional Parmesan cheese and fresh basil, if desired. Enjoy this comforting dish that’s sure to please!
