Recipe Questions & Answers

Can I make this soup without roasting the squash first?

Yes, you can skip roasting and cook the cubed squash directly in the pot with the onions and carrots. Add about 10 minutes to the simmering time to ensure the squash becomes completely tender before blending.

How long does this soup keep in the refrigerator?

This soup stores well in an airtight container for up to 5 days. The flavors actually improve overnight as the spices meld together. Reheat gently on the stovetop, adding a splash of water or broth if needed to adjust consistency.

Can I use green or brown lentils instead of red?

Red lentils work best because they break down easily and create a creamy texture. Green or brown lentils hold their shape and won't blend as smoothly, resulting in a chunkier soup. If substituting, expect a different texture and increase cooking time by 10-15 minutes.

Is this soup freezer-friendly?

Absolutely. Let the soup cool completely before transferring to freezer-safe containers, leaving space for expansion. It freezes well for up to 3 months. Thaw overnight in the refrigerator and reheat on the stovetop.

What can I serve alongside this soup?

Crusty bread, naan, or roasted focaccia are perfect for dipping. A simple green salad with vinaigrette balances the richness. For a more substantial meal, serve with a grain bowl or roasted vegetables.

How can I make this soup creamier?

Add a splash of coconut milk or heavy cream before blending for extra richness. You can also blend in a boiled potato or use an immersion blender longer to create an ultra-smooth texture.
