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 your baking sheet. Drizzle with olive oil, then sprinkle with chilli flakes, kosher salt, and black pepper. Toss everything together using your hands until well coated. Roast in the oven for about 25–30 minutes until tender and slightly charred at the edges.
Step 3: Sauté Onions
While the vegetables roast, heat a large saucepan over medium-high heat. Once hot, add olive oil along with the finely diced yellow onion. Sauté for about five minutes until softened and golden around the edges.
Step 4: Add Garlic and Spices
Stir in crushed garlic along with smoked paprika, ground cumin, onion powder, and dried thyme. Cook while stirring for about thirty seconds to release their flavors.
Step 5: Incorporate Red Lentils
Add red lentils to the pot and stir well to coat them in the onion-spice mixture. Pour in the chicken or vegetable stock along with sea salt; bring this mixture to a boil.
Step 6: Combine Roasted Vegetables
Lower the heat to simmering point before adding in your roasted vegetables. Allow everything to cook together for about fifteen minutes until the lentils are soft.
Step 7: Blend Until Smooth
Carefully transfer all contents into a blender. Cover with a tea towel to avoid splashes as you blend slowly at first. Increase speed gradually until you achieve a smooth consistency. If you prefer thinner soup, add more stock at this stage.
Step 8: Taste & Serve
Taste your soup, adjusting seasoning with more salt or pepper if necessary. Serve topped with dollops of Greek yogurt, pumpkin seeds, fresh thyme leaves, or alongside cheesy toasts as desired. Enjoy!
