Butternut Squash Lentil Soup

Featured in: Cozy Weeknight Meals

This warming bowl combines roasted butternut squash with red lentils, creating a velvety base enhanced by carrots, onions, and fragrant spices. The roasting process deepens the squash's natural sweetness, while cumin, coriander, turmeric, and a hint of cinnamon add layers of aromatic complexity. A splash of lemon brightens the finish, balancing the earthy lentils.

Perfect for meal prep, this keeps well for days and freezes beautifully. The texture is luxuriously smooth when blended, though you can keep it slightly chunky if preferred. Add coconut milk for extra richness or more chili flakes for heat.

Meanwhile, in a large pot, heat the remaining 1 tbsp olive oil over medium heat. Add onion and carrots; sauté for 5 minutes until softened.

Zusatztipps für die Zubereitung

For the best results, ensure your chef's knife is sharp for peeling and cubing the squash. When blending, an immersion blender is the easiest tool for safety and convenience, though a regular blender works well if you work in small batches. Always check your vegetable broth labels if you are strictly avoiding hidden allergens.

Varianten und Anpassungen

If you don't have red lentils on hand, yellow split peas make an excellent substitute, though you will need to increase the simmering time accordingly. For those who enjoy a bit of heat, feel free to be generous with the chili flakes or even add a dash of hot sauce before serving.

Serviervorschläge

This soup pairs beautifully with a side of crusty artisan bread or warm naan for dipping. To make it even more satisfying, you can top individual bowls with a few extra roasted squash cubes or a sprinkle of toasted pumpkin seeds.

Common Questions

Can I make this without an immersion blender?

Yes, use a regular blender in batches, or leave it chunky for a rustic texture. The lentils soften enough to make blending optional.

How long does this keep in the refrigerator?

This stores well for 4-5 days in an airtight container. The flavors actually develop and improve after sitting.

Can I use other types of lentils?

Red lentils work best as they break down easily. Brown or green lentils hold their shape—great if you prefer texture but adjust cooking time accordingly.

Is freezing recommended?

Absolutely. Freeze in portions for up to 3 months. Thaw overnight and reheat gently, adding a splash of broth if needed.

What pairs well with this?

Crusty bread, naan, or crackers are ideal. A simple side salad or roasted vegetables complete a satisfying meal.
