How to Make Roasted Butternut Squash and Red Pepper Soup
Step 1: Preheat the Oven
Preheat your oven to 200°C/400°F. Line a baking sheet with parchment paper to prevent sticking.
Step 2: Roast the Vegetables
Add the diced butternut squash and chopped red peppers to the baking sheet. Drizzle with olive oil, then sprinkle with chilli flakes, salt, and pepper. Toss everything together until well coated. Roast in the preheated oven for 25-30 minutes until tender with slightly charred edges.
Step 3: Sauté Aromatics
While the vegetables roast, place a large saucepan over medium-high heat. Add olive oil along with finely diced onion. Sauté for about 5 minutes until softened and golden at the edges.
Step 4: Add Garlic & Spices
Stir in crushed garlic along with smoked paprika, ground cumin, onion powder, and dried thyme. Cook while stirring continuously for about 30 seconds until fragrant.
Step 5: Incorporate Lentils & Stock
Add red lentils into the pot, stirring well to combine them with onions and spices. Pour in chicken or vegetable stock along with sea salt; bring this mixture to a boil.
Step 6: Combine Roasted Vegetables
Once boiling, reduce heat to a simmer. Add your roasted vegetables into the pot. Continue simmering for about 15 minutes until lentils are soft.
Step 7: Blend Until Smooth
Carefully transfer everything into a blender. Cover the top with a tea towel to avoid splashes as you start blending slowly; increase speed until completely smooth. If you prefer a thinner soup consistency, add more stock here.
Step 8: Season & Serve
Taste your soup; add more salt or pepper if needed. Serve hot topped with Greek yogurt and pumpkin seeds if desired. Check notes below for instructions on making cheesy toasts perfect for dipping!

Common Mistakes to Avoid
Making Roasted Butternut Squash and Red Pepper Soup can be straightforward, but there are common pitfalls that can affect the taste and texture. Here are some mistakes to watch out for:
- Ignoring vegetable size: Not chopping your vegetables into uniform sizes can lead to uneven cooking. Aim for ½ inch dice for even roasting and blending.
- Overcrowding the baking sheet: Placing too many vegetables on your baking sheet can cause them to steam instead of roast. Spread them out for better caramelization.
- Skipping the seasoning: Failing to season your soup properly can result in bland flavors. Be generous with spices like smoked paprika and cumin for depth.
- Not blending thoroughly: Leaving chunks in the soup can affect its creaminess. Blend until completely smooth, adding stock if needed to reach desired consistency.
- Neglecting garnishes: Skipping toppings like yogurt or pumpkin seeds can make your soup feel incomplete. These add flavor, texture, and visual appeal.
