01 - Heat a large, deep skillet over medium heat. Add the reserved sun-dried tomato oil.
02 - Add minced garlic and sliced sun-dried tomatoes. Sauté for 2–3 minutes until fragrant.
03 - Pour in uncooked pasta and vegetable broth. Stir well, bringing to a gentle boil.
04 - Reduce heat to medium-low. Simmer uncovered for 10–12 minutes, stirring occasionally, 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 thickens.
06 - Add grated Parmesan, stirring until sauce is creamy. Season with salt and black pepper to taste.
07 - Remove from heat. Let pasta rest 2 minutes before serving for optimal creaminess.
