Equipment
- 6-quart slow cooker Or larger; a 6-quart is the minimum recommended size for this recipe
- Box grater For freshly shredding block cheese — do not use pre-shredded bagged cheese
- Large mixing bowl
- Wooden spoon or silicone spatula
- Measuring cups
- Measuring spoons
- Ladle or large serving spoon
- Slow cooker liner bags (optional) Makes cleanup significantly easier
Ingredients
- 1 lb elbow macaroni 450g, uncooked — do not cook before adding
- 4 cups whole milk 960ml; do not substitute with low-fat or skim milk
- 12 oz evaporated milk 340g / 1 can
- 2 cups sharp cheddar cheese About 225g, freshly shredded from a block
- 1 cup Gruyère cheese About 115g, freshly shredded
- 1 cup mild cheddar cheese About 115g, freshly shredded
- 4 tbsp unsalted butter 57g, cut into small cubes
- 8 oz cream cheese 225g, cubed and softened to room temperature
Seasonings
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp dry mustard powder Enhances cheese flavor; does not taste like mustard
- 1/2 tsp smoked paprika
- 1 tsp salt Plus more to taste
- 1/2 tsp black pepper
- 1/4 tsp cayenne pepper Optional; adds subtle depth without making the dish spicy
For Garnish (Optional)
- smoked paprika For sprinkling over finished dish
- extra shredded cheddar cheese For topping before serving
- freshly cracked black pepper For finishing
Instructions
- Spray the interior of your 6-quart slow cooker with non-stick cooking spray, coating both the bottom and sides. If using a slow cooker liner, insert it now and press it snugly against the sides.
- Pour the uncooked elbow macaroni into the prepared slow cooker, then pour in the whole milk and evaporated milk, stirring gently so the pasta is well coated and mostly submerged.
- Distribute the cubed butter evenly over the pasta, then add the softened cream cheese cubes on top — do not stir yet, just let them rest on the surface.
- Sprinkle the garlic powder, onion powder, dry mustard, smoked paprika, salt, black pepper, and optional cayenne pepper evenly over the surface, then give the liquids a gentle stir to combine the seasonings.
- Scatter the sharp cheddar, Gruyère, and mild cheddar evenly over the top of the pasta mixture — do not stir the cheese in, just let it sit on top to melt down slowly during cooking.
- Place the lid on the slow cooker and cook on LOW for 2 to 2.5 hours — do not cook on HIGH, as this causes the dairy to break and the pasta to become mushy. Stir gently once at the 1-hour mark.
- At the 2-hour mark, remove the lid and stir well. If the sauce is too thick, stir in a splash of warm whole milk; if too thin, leave the lid off for the remaining 15–20 minutes to allow it to thicken. Taste and adjust seasoning.
- Switch the slow cooker to WARM and allow the mac and cheese to rest for 5–10 minutes before serving, then stir once more, garnish with smoked paprika, extra cheddar, or black pepper, and serve immediately.
Notes
- Always shred your own cheese: Pre-shredded bagged cheese contains anti-caking agents that prevent smooth melting. Block cheese shredded fresh gives you a far creamier sauce.
- Low heat is essential: Never cook this recipe on HIGH. High heat causes dairy proteins to break, resulting in a grainy or separated sauce. Stick to LOW the entire time.
- Soften the cream cheese: Let cream cheese sit at room temperature for at least 30 minutes before starting. Cold cream cheese won't melt smoothly and can leave lumps in the sauce.
- Don't lift the lid too often: Resist peeking until the 2-hour mark. Every time you lift the lid, you lose heat and steam that the pasta needs to cook through.
- Sauce too thick after cooking? Stir in whole milk one tablespoon at a time until it reaches your preferred consistency. The sauce thickens as it cools, so add a splash when reheating too.
- Make-ahead tip: This recipe can be made up to 4 days ahead and refrigerated in an airtight container. Reheat on the stovetop over medium-low heat with a splash of milk, stirring frequently.
- Freezer storage: Freeze in a freezer-safe container for up to 2 months. Note that pasta may soften slightly after freezing and thawing — best enjoyed fresh or from the fridge.
- Cheese substitutions: No Gruyère? Swap it for fontina, Gouda, or Comté for a similar nutty, melty result. Avoid very aged or hard cheeses, which don't melt as smoothly.
- Add-in ideas: Stir in crispy bacon, shredded rotisserie chicken, steamed broccoli, or diced jalapeños during the last 15 minutes of cooking to customize the dish.
- Potluck tip: Keep the slow cooker on WARM for up to 1 hour for serving at parties. Stir occasionally and add a small splash of milk if the sauce begins to thicken too much.
