There is nothing like a hot bowl when the air turns sharp and your hands need warming. This recipe is a healthy roasted vegetable soup that uses red peppers and cauliflower to make something simple feel comforting and a bit indulgent, without any dairy.
I first made it during an autumn when my market bag was too full of peppers and a stubborn head of cauliflower sat on the counter. I roasted them until the edges caramelised, simmered them briefly in warmed stock, then blended until silky. It felt like cooking kindly, which is my thing: low waste, simple pantry staples, and honest flavour. Olive the cat watched the whole time and judged my stirring technique.
It is easy. Roast. Simmer. Blend. The cauliflower gives the body and the peppers bring a smoky sweet note. If you want to call that fall comfort food, go ahead. I do.
Heat the oven to 400 °F.
On a large baking sheet, place the cauliflower chunks and red pepper halves. Drizzle with 1 tablespoon olive oil and sprinkle with salt and black pepper to taste. Toss to coat well.
Roast for 25 minutes until tender.
Once the vegetables are almost done roasting, heat a Dutch oven or large pot over medium-low heat and add 1 tablespoon olive oil. Add in 1 diced onion, 2 minced garlic cloves, ½ teaspoon dried thyme, and 1 teaspoon smoked paprika and cook until the onions are translucent, about 5 minutes.
Add in the roasted vegetables and 5 cups heated vegetable stock and stir to combine.
Simmer for about 15 minutes.
Blend until smooth using a handheld blender or food processor with the blade attachment.
Serve hot with your choice of toppings.
To make this without faff, you will need an oven set to 400 degrees Fahrenheit for the roasting. A large baking sheet with a rim is handy so the veg do not slide off, and a sharp knife and sturdy board for the onion and garlic. Use a heavy pot or Dutch oven for the stovetop work so the heat spreads evenly and nothing catches. I use my battered cast iron from Berlin. It has character.
An immersion blender is ideal for finishing the soup right in the pot. If you do not have one, a food processor or a regular blender works just as well; blend in batches to avoid spills. A wooden spoon, measuring spoons for the thyme and smoked paprika, and a ladle for serving complete the list. Nothing fancy. Just reliable tools you already own.
Here are the little things that save the day. First, spread the cauliflower and pepper halves out on the sheet so they roast and get some colour. If you crowd them they steam and lose that roasted note. I learned that the hard way when I tried to cram too much into a small tray at Glastonbury. Space matters.
Warm the vegetable stock before you add it. Pouring cold stock slows everything down and can make the final soup taste watery. Warm stock keeps the pot lively and helps spices like smoked paprika come through. For that creaminess without any dairy, rely on the cauliflower. Blend it properly until it feels silky. A quick pulse will leave gritty bits, but patient blending answers the classic question of how to make vegan soup creamy.
I often add a swirl of coconut cream at the end for mouthfeel because I like the softness it brings. If coconut is not for you, this is a dairy free soup recipe that also works with a spoonful of tahini or a little soaked cashew, stirred in off the heat. Taste as you go and season after blending so the salt hits the whole bowl evenly.
If onions stick while cooking, splash in a little stock to lift the browned bits. I picked this up in Lyon and it builds real depth. Use low sodium stock from the shop so you can control the seasoning yourself. Fresh parsley chopped on top brings a bright note and a bit of texture. Trust me, it lifts the whole thing.
Spice it up: swap smoked paprika for chipotle powder and add a diced jalapeno with the garlic for heat. This keeps the cauliflower as the creamy backbone but gives the bowl a slow building warmth.
Herb garden version: stir in chopped basil or cilantro and a handful of spinach after blending for a fresher feel. Makes it lighter and bright. I do this when I have too many herbs from the market bag.
Nutty cream boost: blend in a quarter cup of soaked cashews during pureeing for extra silkiness. Soak the nuts overnight so they blend smoothly. This little addition makes it feel a touch luxurious without any dairy.
This is a friendly one pot soup when you want fewer dishes: roast, then do the simmering and blending in the same pot you used for the onions. It keeps things easy and the flavours concentrated.
Ladle the soup into bowls and finish with a drizzle of coconut cream or a scattering of toasted pepitas for crunch. I like a chunk of crusty spelt bread from my Berlin baking days for dipping, or a simple mixed leaf salad with lemon dressing to cut through the richness.
For a heartier meal, spoon the soup over quinoa or brown rice so the grains soak up the broth. If you chill it and serve cool in summer, it still works but I prefer it hot. Leftovers reheat gently on the stove with a splash of stock to loosen the texture.
If you want to avoid coconut, try tahini or almond butter stirred in at the end, off the heat. I once made a batch for a friend with allergies and a spoonful of tahini gave it a lovely, nutty silk. Soaked cashews blended in during pureeing also work well. These are simple swaps that still answer how to make vegan soup creamy.
Yes. After roasting, use your same pot to soften the onions, add the stock and roasted veg, simmer briefly, then blend in the pot. It saves washing up and concentrates the flavours. From my cafe days, efficiency is everything.
Roast leftovers simply with olive oil and spices, pulse into cauliflower rice for stir fries, or mash it as a potato alternative. This answers what to do with cauliflower beyond soup. I store extra florets in an airtight tub for up to four days and find they come in handy for quick dinners.
Yes. It freezes well, so make a big pot and portion it for later. Thaw in the fridge and stir in a little stock when reheating. The flavours often taste better the next day, honestly.
Ingredients to keep as written: 1 head cauliflower cut into chunks, 5 red bell peppers halved, 2 tablespoons olive oil divided, salt and pepper to taste, 1 large onion diced, 2 garlic cloves minced, 1 half teaspoon dried thyme, 1 teaspoon smoked paprika, about 5 cups warmed vegetable stock, coconut cream to taste, and fresh parsley for garnish.
This is also a reliable blender soup recipe if you prefer to blitz in batches in a regular blender. It is a versatile, forgiving bowl that reflects my kitchen philosophy: cook kindly, waste nothing, and share what you can.
