I had pretty ambitious plans for this month but due to circumstances out of my control I am stuck at home and most of my time is spent in the kitchen.
Nothing seemed as satisfying as rich and robust beef bolognese sauce over spaghetti or tagliatelle. It’s one of those cozy dinners you always want to have at the end of a long day.
Somehow it gives you comfort to know that no matter what storm is raging outside, there is always comfort found at home.
How to make authentic bolognese sauce
My usual and easy way of cooking beef bolognese sauce is low and slow in my trusty cast iron pot. The magic trick to making the best beef bolognese is patience.
Just when you think it’s done and want to take it off the heat, keep it on for another hour or two. Through many trials I learned, what makes beef bolognese sauce (and its vegetarian cousin made with mushrooms) is time. And tomatoes of the best quality!
So when you go shopping for your ingredients, do choose best canned tomatoes you can find. You will be surprised how sweet and flavourful beef bolognese sauce will taste made with perfectly ripe tomatoes!
However if you are not lucky enough to find ripe canned tomatoes, adding 1 tablespoon of sugar to your sauce also helps.
The usual suspects in almost every beef bolognese sauce are beef, tomatoes, basil, oregano as well as diced onions, carrots, celery and some garlic.
I also add just a small amount of smoked pancetta or bacon for flavour, and that little addition makes a world of difference, as was once pointed out by my father-in-law!
I usually start by frying the pancetta, and then add all diced vegetables and sauté everything for a few minutes. Until a couple of days ago, I believed this step was crucial for the flavour development.
How to make slow cooker spaghetti sauce
When I set out to develop a slow cooker bolognese sauce recipe, I naturally wanted to simplify the process. What is the point of a slow cooker if you cook everything in the pan first?!?
So I took the risk and added all the vegetable raw. The only things I pre-cooked were bacon and beef. I was curious if that method would yield the same flavour.
Well as soon as my son finished his first helping, he said, “I don’t know why but this beef bolognese sauce tastes better than what you usually make”. Woah! The magic of a slow cooker!!
Alternatively, you can make this sauce in your Instant Pot, which speeds up the process significantly. It will be ready in one hour instead of 8!
Right, let’s get to it! Below you will see the stages of cooking this wonderful beef bolognese sauce.
In the second row of photos you can see what the sauce will look like at the beginning, 5 hours later and 8 hours later.

This slow cooker bolognese sauce recipe produces A LOT OF sauce. I usually divide it and freeze a half of it for later. This delicious sauce could be used in my three cheese lasagna recipe.
How to make a smooth sauce
If you prefer a less chunky sauce, I would recommend adding all the vegetables to a food processor first and pulsing them for a few seconds.
With this method you will have the same flavour, quicker and a smoother sauce. I often do that to speed up the process and eliminate all the dicing!
