Ingredients for the Soup

4 cups Zucchini (Fresh)
1 large White Onion (Or yellow onion)
1 tablespoon Fresh Thyme
1 tablespoon Fresh Oregano
1 teaspoon Kosher Salt (Adjust to taste)
1 teaspoon Black Pepper (Adjust to taste)
1 head Garlic (Fresh, roasted)
4 cups Chicken Bone Broth or Vegetable Broth
1 cup Feta Cheese (Reduced-fat for lower calories)
2 tablespoons Extra Virgin Olive Oil (High quality for best flavor)
2 tablespoons Fresh Dill (Or parsley if unavailable)
1 tablespoon Optional Extra Olive Oil (For drizzling before serving)

How to Make the Soup

Preheat the oven to 400°F (204°C).
Trim the ends of the zucchinis and cut them into roughly 1–1½-inch pieces.
Peel and quarter the white onion.
Slice the top off the head of garlic to expose the cloves.
Place the zucchini pieces, onion quarters, fresh thyme, and oregano in a large baking dish or on a sheet pan.
Season with kosher salt and black pepper, drizzle with extra virgin olive oil, and toss to coat evenly.
Nestle the garlic head cut-side up among the vegetables.
Create a small well in the center of the pan and set the block of feta there; drizzle a little more olive oil over the feta.
Roast for 30–35 minutes, until the zucchini is tender and the feta is golden and slightly bubbly.
Remove the pan from the oven and squeeze the softened roasted garlic cloves from their skins.
Transfer the roasted zucchini, onion, roasted garlic, and baked feta into a blender.
Add the chicken bone broth or vegetable broth to the blender.
Blend on high until very smooth and velvety, scraping down the sides as needed; add more warm broth a little at a time if the soup is too thick.
Taste and adjust seasoning, keeping in mind the feta adds salt.
To serve warm, gently reheat the blended soup on the stove over low heat until heated through, stirring occasionally; to serve chilled, cool to room temperature then refrigerate for at least 1 hour.
Ladle into bowls and garnish with fresh dill or parsley, extra crumbled feta, and a drizzle of olive oil.
