Sauté the onion

• Melt the butter in a large pan over medium heat.
• Add the onion and sauté until soft.

Simmer the pasta

• Add the pasta and chicken broth.
• Stir and bring to a gentle simmer.
• Stir occasionally as the pasta cooks.

Add the broccoli

• Add the uncooked broccoli in the last minutes of cooking.

Make it creamy

• Once the pasta is al dente and most of the broth is absorbed, lower the heat.
• Stir in the Boursin until melted.
• Add a splash of heavy cream if desired and the grated parmesan.
• Stir until creamy and smooth; add more broth if the sauce is too thick.

Season and serve

• Season with salt and pepper to taste.
• Serve topped with more parmesan cheese.
