01 - Heat a large, deep skillet or sauté pan over medium heat. Add the reserved sun-dried tomato oil and warm through.
02 - Add the minced garlic and sliced sun-dried tomatoes to the pan. Sauté for 2–3 minutes until fragrant and the garlic is lightly golden.
03 - Pour in the uncooked pasta and vegetable broth. Stir well to combine, then bring to a gentle boil.
04 - Reduce heat to medium-low. Simmer uncovered for 10–12 minutes, stirring occasionally to prevent sticking, until pasta is nearly al dente and most of the liquid is absorbed.
05 - Stir in heavy cream, Italian herbs, red pepper flakes, and fresh spinach. Cook for another 2–3 minutes until the spinach wilts and the sauce begins to thicken.
06 - Add grated Parmesan, stirring constantly until the cheese melts and the sauce becomes creamy and velvety. Season with salt and black pepper to taste.
07 - Remove from heat and let the pasta rest for 2 minutes before serving to allow the sauce to reach optimal consistency.
