Kitchen Equipment

- Wooden spoon
- Sharp knife
- Cutting board
- Blender or immersion blender
- Measuring cups and spoons
- Soup bowls
Step 1: Prepare the Vegetables
Wash the zucchini thoroughly under cold running water. Trim both ends and cut them into small chunks. Keeping the skin on adds nutrients and a beautiful green color.
Peel and dice the onion into small pieces.
Peel and finely mince the garlic cloves.
Set all vegetables aside.
Step 2: Cook the Onion
Place a large soup pot over medium heat.
Add the butter and olive oil.
Once the butter melts, add the diced onion.
Cook for about 5 minutes, stirring occasionally until the onion becomes soft and translucent.
Avoid browning the onions because you want a delicate flavor.
Step 3: Add Garlic
Add the minced garlic to the onions.
Cook for 30–60 seconds until fragrant.
Do not let the garlic burn, as burnt garlic tastes bitter.
4: Cook the Zucchini
Add the chopped zucchini to the pot.
Stir well to coat the zucchini in the butter and onion mixture.
Cook for 5 minutes, stirring occasionally.
The zucchini should begin to soften slightly.
Step 5: Add the Broth
Pour in the chicken broth or vegetable broth.
Add:
- Salt
- Black pepper
- Thyme
- Oregano
- Paprika (optional)
Stir everything together.
Bring the soup to a gentle boil.
Step 6: Simmer
Reduce the heat to low.
Cover the pot with a lid.
Allow the soup to simmer for 15–20 minutes.
The zucchini should become very soft and easy to mash with a spoon.
Step 7: Blend the Soup
Turn off the heat.
Use an immersion blender to blend the soup until completely smooth.
If using a countertop blender:
- Blend in small batches.
- Never fill the blender more than halfway.
- Leave the lid slightly open with a towel covering it to allow steam to escape.
Blend until silky smooth.
Step 8: Add Cream
Return the soup to low heat.
Pour in the heavy cream.
Stir continuously for about 2 minutes.
The soup will immediately become richer and smoother.
Step 9: Add Cheese
Slowly stir in:
- Parmesan cheese
- Shredded cheddar cheese
Keep stirring until all the cheese melts completely.
If using cream cheese, add it now and stir until smooth.
Avoid boiling the soup after adding dairy, as high heat may cause it to separate.
Step 10: Taste and Adjust
Taste the soup.
If needed, add:
- More salt
- More pepper
- Extra Parmesan cheese
- A little more cream for richness
Adjust the seasoning according to your preference.
Step 11: Serve
Ladle the hot soup into large serving bowls.
Top with:
- Extra shredded cheddar cheese
- Fresh parsley
- Fresh thyme
- Cracked black pepper
Serve immediately while hot.

Frequently Asked Questions
Can I leave the zucchini skin on?
Yes. The skin becomes tender during cooking and adds nutrients, fiber, and a natural green color.
Can I use frozen zucchini?
Yes. Thaw and drain it first to prevent excess water from thinning the soup.
Why is my soup too thin?
Simmer it uncovered for a few extra minutes, or add a little more grated Parmesan or cream cheese to thicken it.
Can I make this soup ahead of time?
Absolutely. The flavors deepen after a day in the refrigerator. Reheat gently over low heat, stirring occasionally.
What can I use instead of heavy cream?
Half-and-half, whole milk, evaporated milk, or coconut cream all work, though the soup may be slightly less rich.
