How To Make Minestrone Soup In A Slow Cooker

Like many of my slow cooker recipes, this one opts for the simplest and quickest way to make something tasty! 

For this recipe, I just add everything into the slow cooker, apart from the pasta and spinach (this gets added 20-30 minutes before the end), put the lid on and set it off.

What You Need

This Italian soup is intended to be thick and full of a variety of vegetables, pasta, tomatoes and optionally some smokey bacon.

The great thing is you can add in whichever vegetables you have available – just keep some small pasta shapes in the cupboard as well as some tinned tomatoes or passata for when the mood takes you, or you have some excess vegetables to use up.

minestrone ingredients in slow cooker

This recipe uses onions, garlic, courgettes, celery, carrots and spinach. You could add in or substitute with potatoes, cabbage and some beans such as cannellini or butter bean.

If you have an abundance of flavoursome fresh tomatoes you can use those instead of tinned tomatoes or passata. 

You can use any dried pasta for minestrone soup, but try and use the smaller variety, or, break up some spaghetti to add in.

You can optionally saute the onions, garlic and bacon in a little oil before adding them to the slow cooker – if you are not adding bacon I would skip this step.

Add everything to the slow cooker apart from the pasta and spinach. Set it off on low for 6 to 8 hours, or high for 3 to 4 hours.

adding pasta to minestrone soup

Remove the lid at this point and add in the pasta and spinach leaves, stirring them in so that they are submerged. Replace the lid and continue to cook for a further 20 to 30 minutes or until the pasta has softened.

Serve in a bowl with some grated parmesan cheese on top and optionally some crusty bread to dunk in.

How Do You Thicken Minestrone Soup?

The consistency of minestrone soup can vary depending on what vegetables you put in, the type of pasta, as well as the type of tomatoes – even down to the brand of tinned tomatoes. If your soup ends up being too thin, add in a larger quantity of pasta when it’s time to add it in or leave the lid off for 20 minutes of slow cooking time at the end to allow it to boil down some more.

How Do You Make Minestrone Soup Thinner?

Minestrone soup is intended to be thick, but if you prefer a thinner soup, stir in some extra vegetable stock.

How Long Does Minestrone Soup Last?

It will last for up to 3 days in the fridge (leave it to cool first), or you can freeze it for up to 3 months.

How Do You Reheat Minestrone Soup?

You can reheat it in a saucepan until it is hot all the way through. If it is too thick you might need to add in some extra water or stock. If you have frozen the minestrone soup, defrost it thoroughly before reheating it.
