When the weather is grey and I crave something comforting and warming, this sheet pan carrot and red pepper soup is something I make on repeat. It's like sunshine in a bowl! It's such a simple recipe - the vegetables roast together on a tray and then get blended into a thick, velvety soup with a gentle garlic and leek savoury base and a hint of fennel. Just prepare the vegetables, pop in the oven and finally blend. The results? A flavourful vegan soup that is great for wintery evenings or even a nutritious light lunch.
If you like this simple, straightforward sheet pan soup, then also try my roasted tomato, leek and red pepper soup.

Why You'll Love This Carrot and Red Pepper Soup
- One sheet pan (baking tray), minimal washing up, more time - Everything roasts together in the oven and then straight into the blender.
- Naturally vegan and gluten free - Made with vegetables, olive oil and vegetable stock. If you use shop-bought stock cubes, check the ingredients list on the packet for dairy products / gluten.
- Sweet, rounded flavour - Roasting the vegetables brings out their natural sweetness. The garlic and the leek provide a subtle savoury base, letting the other flavours shine. The fennel gives a pleasing anise note.
- Freezer friendly - This is a great recipe for busy lifestyles. Batch cook and freeze!
- Budget friendly - Just a few vegetables, and you can even use up ones that are past their best.
Right then, lets cook!

Key Ingredients and Notes

- Carrots - Loverly mellow sweetness when roasted.
- Red pepper - Gives a nice peppery / smoky kick to the soup.
- Leek - Provides a mellower taste than onion, giving room for other flavours to shine.
- Garlic - Savoury flavour base for the soup.
- Fennel seeds - Provides an anise accent to liven up the soup.
- Vegetable stock - I make my own vegetable stock, but, of course, use stock cubes otherwise.

FAQs - quick glance
Absolutely. This is a quick, simple recipe that you can batch cook and freeze for up to four months. Defrost in the fridge overnight.
Experiment with different herbs. Of course the taste will be different - go with what you like. Perhaps Coriander seeds, Dill seeds or Caraway seeds. Use the same quantities as the Fennel seeds and add to the sheet pan in the same way as the Fennel seeds.
I like to blend the soup to a point where it has a some texture. Not silky smooth, but slight chunky. It feels more rustic and hearty.
Yes, and I highly recommend that you make your own as you know what's going into it and can rest assured it is vegan and gluten free. It is a great way to make valuable use of your vegetable peelings as well. Have a look at my "How to make vegetable stock like a chef" recipe.

Simple and tasty. I roasted the carrots on a separate tray as they take longer.
Chef Tripti says
Thank you very much for this feedback! Yes, carrots are a harder vegetable - I put them all into the same tray and cook till the carrots are soft, aiming for the softer vegetables to cook to a point of being slightly caramelised to add a smokey flavour to the soup. I find that as long as I cut the carrots to approximately half-an-inch slices, then all cook together to the desired point ready for blending.

My son found this recipe online and started making it for us a couple of weeks ago. It is so delicious that I cannot get enough of it! It's now part of our family's weekly routine to stop by the local farmer's market for the carrots, peppers, garlic and (his addition) onion. As well as any other veggies we need for the week.
