How to Make Roasted Red Pepper Soup

Equipment I Use

First, let's talk about what equipment I used and any alternatives you may have at hand.

Soup Maker Red Pepper Soup

Note that a soup maker is not vital for roasted red peppers soup. But when making healthy soup recipes for a soup maker, or any for that matter.

The thing is, a soup maker has a limit of what you can put in it and usually makes between 1300-1600ml. Any more or less and it won't turn on. I tend to solely focus on making them in my machine as a priority, knowing that they cook this recipe red pepper pot soup, too.

Roasted Red Pepper Ingredients

6 red peppers halved and deseeded
2 tbsp olive oil
½ tsp fine sea salt
¼ tsp cracked black pepper
1 tbsp oregano

200 g cauliflower raw or frozen
600 ml water or 700ml (up to the 1600ml line of soup maker)
1 red onion diced
1 tbsp smoked paprika
60 g cream cheese
2 chicken stock cubes *optional and stir in last if you feel you need it
100 ml single cream

Alternative Ingredients

If you're not looking for a keto red pepper soup, you can:

Swap the cauliflower for a potato, beans
Add more fresh herbs instead of relying on stock cubes with additives
If you can't make fresh roasted red peppers, then 6 red peppers are the equivalent of 3 x 16oz jars of roasted red peppers, with 2 peppers in each.

How to Make Easy Red Pepper Soup

Roasting peppers may not sound like an easy way to make soup. But it's actually your oven that will be doing most for work.

But to make my my keto bell pepper soup, I:

Preheat your oven at 210c fan / 230c conventional / Gas Mark 8 / 450F
Place the halved peppers, oil, salt, pepper and oregano in a lidded storage tub, close, then give it a good shake until everything is coated.
Next, spread everything on a baking tray with silicone mat (or baking paper) and roast in the oven for 40 minutes.
Once done, pour the oil from the tray into a large saucepan or a soup maker with saute function and saute the red onions.
Then add the remaining ingredients except the cheese and cream. Soup Maker: Add the water last if using a soup maker to see if you need to add more or less up to the 1600ml line.
Simmer for 20-22 minutes or set the soup maker to smooth.
Blend along with the cheese, then serve, drizzle with cream and garnish with fresh herbs of your choice.

Can I Make Roasted Red Pepper Soup Vegan?

To make a creamy vegan red pepper soup, simply:

Use a vegan cheese to blend in at the end
Ensure you stir in Vegan cream. Note, I used Elmlea plant based single cream
Use a vegan stock if you opt for it, such as Marigold bouillon powder, (usually in a purple tub)

Storing Your Easy Red Pepper Soup

To store, I leave mine in an air tight container for keep in the fridge for up to 5 days. I find it easier to heat up in a lidded microwavable container or simmer on low on the hob to spatter prevent mess.

Can You Freeze Red Roasted Pepper Soup?

Yes, roasted red pepper soup is perfect for freezing! Again, my Sistema soup containers are also safe for freezing, which I tend to store for up to 3 months.

On the day of eating, I'll defrost fully in the fridge or use my microwave defrost setting. Then heat for 2 minutes, stir and heat for another 2.

It's also a delicious soup with oat flour cottage cheese scones. I butter them and dunk them in to eat.
