Why I Like this Recipe
I love this recipe because it makes the cheesiest, most comforting mac and cheese ever. The mix of cheeses gives it a rich flavor that just warms me up on a cold day. I also like how easy it is to put together in my slow cooker – it means I can spend less time in the kitchen and more time chilling with my family. Plus, I dig being able to tweak the thickness by adding a splash of milk if it ever seems too thick. Lastly, the combination of garlic and onion powder adds a nice kick without being overpowering, and that really makes the dish stand out for me.

FAQ
SLOW COOKER FOUR CHEESE MAC AND CHEESE Recipe Substitutions and Variations
- If you dont have elbow macaroni, you can try using penne or shell pasta instead.
- If sharp cheddar isn’t available, substituting with Colby cheese or even a mix of cheddar and gouda works great.
- For whole milk, you can use 2% milk mixed with a bit of cream to keep it rich.
- If cream cheese is hard to find, mascarpone can be a good substitute though the consistency might be slightly different.
- Instead of unsalted butter, you can opt for salted butter but be sure to adjust the salt later on.
Pro Tips
1. Make sure you don’t overcook the pasta – al dente is the way to go or you’ll end up with a mushy mess that doesn’t mix well with the cheese sauce.
2. Keep an eye on the sauce as it’s cooking in the slow cooker and stir it a couple of times, so it doesn’t form a crust and burns at the bottom.
3. If the sauce seems too thick, add a splash of milk gradually until you reach the perfect creamy consistency – it’s better to add a little at a time.
4. For an extra cheese flavor, try letting the cream cheese fully melt into the milk mixture by stirring continuously during the first half hour of cooking; it might take a bit more time than you expect.
