👩🍳 How to Make 3-Ingredient Mac and Cheese in the Slow Cooker
This part is as easy as 1-2-3. Here’s the full step-by-step breakdown:
✅ Step 1: Combine the Ingredients
In your slow cooker, add:
- 2 cups elbow macaroni
- 2 cups shredded cheddar cheese
- 2 cups milk
Stir everything together until the cheese is evenly mixed through the pasta.
✅ Step 2: Set It and Forget It
Cover the slow cooker with the lid. Set to LOW and cook for 2 to 3 hours.
✅ Step 3: Check for Doneness
After about 2 hours, check the pasta. It should be tender but not mushy, and the cheese should be fully melted into a creamy sauce.
✅ Step 4: Serve and Enjoy
Once fully cooked, give it one final stir and serve warm. You can leave it on “WARM” if serving later.
✅ Tips for Best Results
Even simple recipes have tricks to get them just right. Follow these tips for the perfect mac and cheese:
✔️ Use Freshly Shredded Cheese
Pre-shredded cheese has anti-caking agents that can make your sauce gritty. For the smoothest sauce, shred your own.
✔️ Don’t Overcook
Check the pasta after 2 hours to avoid mushy texture. Overcooked pasta will fall apart in the sauce.
✔️ Stir Occasionally
Stirring once every hour prevents the pasta from clumping or sticking to the sides.
✔️ Don’t Use Evaporated Milk
Stick with regular milk (preferably whole) for the right consistency. Evaporated milk can make the sauce too thick or sweet.

❓ Common Questions and Answers
Q: Can I cook it on HIGH instead of LOW?
Yes, but keep a close eye on it. Cook on HIGH for 1 to 1.5 hours, stirring every 30 minutes.
Q: Can I double the recipe?
Absolutely! Just use a 6-quart or larger slow cooker and increase cook time slightly. Stir often to ensure even cooking.
Q: Why is my mac and cheese too thick?
This can happen if it cooks too long or loses too much moisture. Add a bit more milk and stir until creamy again.
Q: Why is it watery?
It likely needs more time. The pasta releases starch as it cooks, thickening the sauce. Stir and let cook a little longer.
Q: Can I use other pasta shapes?
Yes, short pasta shapes like shells, rotini, or penne work too, but may cook slightly differently. Adjust time as needed.
