01 - Heat a large, deep skillet or sauté pan over medium heat. Add the reserved sun-dried tomato oil and warm through.
02 - Add 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 uncooked pasta and vegetable broth. Stir well to combine and bring to a gentle boil, ensuring pasta is submerged.
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 liquid is absorbed.
05 - Stir in heavy cream, Italian herbs, red pepper flakes, and fresh spinach. Cook for 2–3 minutes until spinach wilts and sauce begins to thicken.
06 - Add grated Parmesan, stirring constantly until melted and sauce is creamy. Season with salt and black pepper to taste.
07 - Remove from heat and let pasta rest for 2 minutes before serving, allowing sauce to reach optimal creaminess.
