🧀 Ingredients Overview
Let’s take a closer look at the three ingredients that make this dish so simple and satisfying.
1. Elbow Macaroni (2 cups)
The traditional shape for mac and cheese, elbow macaroni cooks evenly in the slow cooker and holds onto the cheese sauce perfectly.
2. Shredded Cheddar Cheese (2 cups)
Cheddar cheese gives mac and cheese its iconic flavor and melt-in-your-mouth texture. Use sharp cheddar for stronger flavor or mild cheddar for a creamier taste.
3. Milk (2 cups)
Milk helps cook the pasta and creates a creamy cheese sauce. Whole milk works best, but 2% is also fine.
🔧 Required Equipment
You don’t need much to make this recipe—just a few basic kitchen tools:
- Slow cooker (4-6 quart)
- Measuring cups
- Mixing spoon
- Grater (if shredding cheese yourself)
A programmable slow cooker with a “warm” function is ideal for keeping the mac and cheese ready to serve at parties or potlucks.
