Ingredients
- 12 oz spaghetti pasta
- 1/4 cup olive oil
- 6 cloves garlic cloves, thinly sliced
- 1 tsp red chili flakes
- 4 cups vegetable broth
- 1 tbsp lemon zest
- 2 tbsp fresh lemon juice
- 1/4 cup fresh parsley, chopped
- 1 1/2 tsp salt
- 1/2 tsp black pepper
- 1/2 cup, optional grated Parmesan cheese
Instructions
- Step 1: In a large deep skillet or sauté pan, heat 1/4 cup olive oil over medium heat. Add 6 thinly sliced garlic cloves and 1 tsp red chili flakes; sauté for 2-3 minutes until garlic is golden and fragrant but not burnt.
- Step 2: Add 12 oz dry spaghetti pasta to the pan, then pour in 4 cups vegetable broth, making sure the pasta is submerged.
- Step 3: Bring the mixture to a boil, then reduce heat to medium-low and simmer uncovered, stirring occasionally, for 10-12 minutes until the pasta is al dente and most of the liquid has been absorbed.
- Step 4: Remove from heat and stir in 1 tbsp fresh lemon zest, 2 tbsp fresh lemon juice, 1/4 cup chopped fresh parsley, 1 1/2 tsp salt, and 1/2 tsp black pepper.
- Step 5: If desired, sprinkle 1/2 cup grated Parmesan cheese over the pasta and toss gently to combine and melt the cheese before serving immediately.
