Heat olive oil in a large pot over medium heat. Add the chopped onion and minced garlic, sautéing for about 5 minutes until they become translucent and fragrant.

Stir in the broccoli florets. Cook for about 2 minutes, stirring gently to lock in delicious flavors.

Pour in the broth, bringing it to a gentle boil. Reduce the heat to a simmer and let it cook for approximately 10 minutes, or until the broccoli is tender.

Blend the mixture using an immersion blender until smooth, or blend until you reach your desired consistency.

Stir in the heavy cream and crumbled feta cheese over low heat until well combined.

Season with salt and pepper to taste, then serve hot.
