Begin by heating the olive oil in a large pot over medium heat. Once the oil is shimmering, add the minced garlic, frying it gently for about 1-2 minutes. Stir continuously to ensure it releases its aroma without burning.
Introduce the pasta to the pot, pouring in the vegetable broth simultaneously. Bring the mixture to a gentle simmer, stirring occasionally to prevent the pasta from sticking together.
After 5 minutes of boiling, add the fresh broccoli florets to the pot. Continue cooking until the pasta is al dente and the broccoli is tender yet vibrant, about another 5-7 minutes.
Once the pasta and broccoli are cooked, lower the heat to a gentle simmer. Slowly stir in the heavy cream and grated Parmesan cheese, mixing well until a rich and creamy sauce forms, coating the pasta evenly.
Add the lemon zest for a fresh kick, then season the dish with sea salt, freshly cracked black pepper, and crushed red pepper flakes if you enjoy some spice. Mix thoroughly to ensure even distribution of flavors.
Remove the pot from heat and allow it to rest for a couple of minutes; this will help the sauce thicken slightly.
Serve the pasta warm, elegantly garnished with fresh basil leaves and an extra sprinkle of Parmesan cheese, if desired, for a beautiful finishing touch.
Notes
Substitute heavy cream with coconut cream for a dairy-free version.
