Step-by-Step Cooking Instructions
- Prepare the slow cooker. Grease the inside with butter or cooking spray to prevent sticking.
- Add ingredients. Pour in uncooked macaroni, both types of cheese, cubed cream cheese, milk, evaporated milk, butter, and seasonings. Stir everything together.
- Cook. Cover and set on low heat for 2 to 2½ hours. Stir every 30–40 minutes to make sure the pasta cooks evenly and the cheese melts smoothly.
- Check texture. After about 2 hours, test the pasta. If it’s tender and the sauce is creamy, it’s ready. If you want a thicker sauce, cook for an extra 15 minutes.
- Serve warm. Garnish with fresh parsley or an extra sprinkle of shredded cheese before serving.
Recipe Notes
- Don’t overcook the pasta—it should be tender, not mushy. Stirring every 30–40 minutes helps keep the sauce creamy.
- Use block cheese that you shred yourself instead of pre-shredded. Pre-packaged shredded cheese often has anti-caking powder, which makes sauces grainy.
- Evaporated milk adds a rich, silky texture. You can replace it with half-and-half if you prefer.
Time and Serving
- Prep Time: 10 minutes
- Cook Time: 2–2½ hours on LOW
- Total Time: About 2 hours 20 minutes

Storage Instructions
- Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat gently on the stove or in the microwave with a splash of milk to loosen the sauce.
- Freezer: Mac and cheese can be frozen for up to 2 months. Let it cool completely, transfer to freezer-safe bags or containers, and reheat in the oven or slow cooker after thawing overnight.
