Treat the pasta liquid as part of the sauce

Use the specified dry-packed sun-dried tomatoes and have the cubed cream cheese ready before heating the skillet. The dry fettuccine cooks in the measured vegetable broth, so it needs contact with the liquid. Break it in half if needed to fit, following the method, and separate clinging strands at each stir.

Keep the liquid in the skillet rather than draining the pasta. If sticking begins before the strands soften, use the stated two-tablespoon water additions and reassess after stirring. Adding a large unmeasured pour would change the sauce the recipe is building around the pasta.

Finish the dairy sauce on low heat

Let the cream cheese melt into the cooking liquid before adding the milk and grated cheese. Low heat and gentle stirring let you see whether the sauce is smooth before the spinach and white beans enter. Fold those in broadly so the beans keep their shape.

Check that the fettuccine is tender as well as checking the hot beans and wilted spinach. Use the method's brief off-heat stand if the sauce remains loose, then toss once more before dividing into four portions. This distributes the sauce and beans through the servings instead of leaving them beneath the pasta.
