Ingredients notes:

- Pasta: The classic choice for this recipe is small macaroni pasta. But it will absolutely work with other small types of pasta if that's what you have in the cupboard.
- Cheese: I used 1 cup of grated mozzarella and 1 cup of Colby cheese but you could use whatever cheese is your favourite or what you have on hand.
- Stock: You can use a stock cube and boiling water, store-bought liquid stock or homemade stock.
Note: Scroll to the recipe card for the ingredients, quantities and the full method.
Step by step instructions:
Add macaroni and melted butter to the slow cooker then sprinkle over flour, stir to coat the pasta.

Add the grated cheese, milk and salt then dissolve the oxo cube in the boiling water, pour in to slow cooker and stir everything together.

Turn onto high and cook for 1 hour and 30-45 minutes. Stirring every 30 minutes to stop pasta sticking to the bottom. Check the pasta is cooked al dente and add more seasoning if desired. The cooking time will vary depending our your slow cooker so keep an eye on it for the last 20 minutes.

You can serve it at this stage or if you want a crispy topping you can sprinkle over panko crumbs and grated cheese, remove the bowl from the slow cooker and put it under the grill in the oven until it is bubbling and golden.

Recipe FAQs:
Absolutely. While macaroni is the ideal pasta shape for this meal, you could easily substitute this out for penne, bowties, or spirals.
This is the perfect dish to freeze! Place in an airtight container and store in the freezer for up to 6 months. Defrost, then heat to piping hot in a saucepan on the stove top.
You could also add some diced ham, cooked bacon or chopped sausage to up the protein in the meal. I wanted to add a crispy topping so put it under the grill at the end with some more cheese and breadcrumbs until it was golden. If you decide to do this make sure your slow cooker bowl is safe to put in the oven under the grill.
Storage:
Store any leftover mac n cheese in an airtight container in the fridge for up to three days. Reheat in the oven or microwave until piping hot.
This recipe can also be frozen. Store any leftovers in an airtight container in the freezer for up to 6 months. Defrost, then heat to piping hot in a saucepan on the stove top.
Top tips:
The timing at the end of cooking is crucial. You want to serve it while the pasta is still al dente with a creamy sauce. If it sits too long the pasta will absorb more of the sauce and go quite soft. Keep an eye on it and keep stirring at the end because the timing will vary from one slow cooker or crock pot to the next.

I normally use a whole bag of macaroni if making macaroni cheese in oven. It feeds 5 of us.
Want to try this recipe. If I was to use a 500g bag of macaroni in the slow cooker do I need to change all the other ingredient amounts? I don't think 2 cups will fill us
VJ cooks says
Yes you will. 2 cups of dried macaroni is roughly 250g. Therefore if you double the macaroni you will need to double everything else.
Lisa says
Hi, can I double the cheddar cheese as I don't have mozzarella cheese on hand today?.
VJ cooks says
Yes that will be fine!
