Instructions

Heat the olive oil in a large deep skillet over medium-low heat.
Add the sliced onions and cook for 20-25 minutes, stirring occasionally, until deeply caramelized.
Stir in the minced garlic and chopped sun-dried tomatoes and cook for 2 minutes.
Pour in the chicken broth and bring to a gentle simmer.
Add the broken spaghetti and fresh thyme, making sure the pasta is mostly submerged.
Cover and cook for 10-12 minutes, stirring occasionally, until the spaghetti is al dente.
Remove the pan from the heat and stir in the lemon juice and grated Parmesan cheese.
Season with salt and black pepper to taste.
Garnish with additional Parmesan cheese and fresh thyme if desired.
Serve immediately while hot.

Notes

Cook the onions slowly for the best caramelized flavor. Stir the pasta occasionally while simmering to prevent sticking, and add a splash of broth if the pasta absorbs the liquid too quickly.
