Ingredients

- Onions: sautéed with garlic for flavor.
- Olive oil: to roast the butternut squash and sauté the onions and garlic.
- Seasoning: salt, pepper, thyme and rosemary are used as seasonings to enhance the flavor of this soup.

Substitutions and Variations

How to Make Roasted Butternut Squash Soup
Step 1: Roast the butternut squash. Peel and cut the butternut squash into chunks. Toss with olive oil, salt, and pepper and garlic cloves in a large bowl until evenly coated. Transfer into a baking tray and roast in the air fryer or oven. Air fryer: roast using bake setting in preheated air fryer for 15-20 minutes at 200°C (about 390°F), stirring every 4-5 minutes. Oven: method, preheat to 200°C (about 390°F) and roast on a baking tray for 30-35 minutes, or until the squash is tender and slightly caramelized, stirring halfway.
Step 2: Sauté onions and garlic. While the squash is roasting, heat olive oil in a pan over medium-high heat. Add onions and green chilies and sauté for 2 minutes. Add the garlic and cover and cook for another 2 minutes.
Step 3: Add cashew nuts. Toss in the cashew nuts and cook for another minute, stirring intermittently.
Step 4: Add the roasted butternut squash and herbs and cover and cook for another 2 minutes.
Step 5: Add water and cover and cook for another 3-4 minutes, stirring every few minutes, then remove from heat.
Step 6: Blend and serve. Transfer the mixture into a blender and blend until smooth. Tip: If your blender is not heat-resistant then allow the mixture to cool before blending. Transfer into serving bowls, garnish with fresh herbs and enjoy!
Experts Tips
- Garlic: whole garlic cloves are roasted with the butternut squash to enhance the flavor of this soup.
- Water: water is added to the pan (rather than the blender), this helps draw out as much flavor from the pan as possible for the soup.
- Even roasting: Make sure the butternut squash cubes are evenly coated with oil and spaced out on baking tray to ensure they roast evenly.
