Ingredients and Preparation

This recipe keeps things simple with common pantry ingredients. If you have dietary preferences or need to substitute ingredients, there are plenty of flexible options provided.

Ingredients

• 1 pound uncooked elbow macaroni
• 2 cups half-and-half
• ½ cup (1 stick) unsalted butter, melted
• 8 ounces cheddar cheese, grated (about 2 cups)
• 8 ounces Monterey Jack cheese, grated (about 2 cups)
• 4 ounces cream cheese, cut into small pieces
• 2 (12-ounce) cans evaporated milk
• 1 teaspoon ground mustard
• Kosher salt and freshly ground black pepper, to taste
• 1 cup cooked, diced chicken or crumbled ground beef (optional)
• Chopped chives, for garnish

Ingredient Substitutions and Alternatives

• Cheese Variations: While cheddar and Monterey Jack provide a great balance of sharpness and creaminess, you can substitute or mix in other cheeses such as Gouda, Colby Jack, or Swiss. Avoid pre-shredded cheese, as it contains anti-caking agents that prevent smooth melting.
• Milk Alternatives: If you don’t have half-and-half, you can use a combination of whole milk and heavy cream. For a lighter version, use whole milk only, though the result may be slightly less creamy.
• Meat Substitutes: If you want added protein, diced grilled chicken or seasoned ground beef blends well with the rich cheese sauce. You can also use plant-based meat alternatives or skip the protein entirely.
• Pasta Choices: While elbow macaroni is traditional, you can use shells, rotini, or cavatappi for a different texture. Just ensure the pasta size is appropriate for even cooking in the slow cooker.

Step-by-Step Instructions

Follow these simple steps to create a delicious, creamy mac and cheese with minimal effort.

Step 1: Prepare the Ingredients

Grate the cheese, cut the cream cheese into small pieces, and measure out all the liquids. If adding chicken or beef, cook and dice it in advance. Having everything ready before you start will make the process smoother.

Step 2: Combine Ingredients in the Slow Cooker

In a 5 to 7-quart slow cooker, add the uncooked macaroni, half-and-half, melted butter, cheddar cheese, Monterey Jack cheese, cream cheese, evaporated milk, and ground mustard. Stir everything together until the ingredients are well combined. Season with salt and black pepper to taste.

Step 3: Start Cooking

Cover the slow cooker with the lid and set it to low. Stir every 30 minutes to ensure even cooking and to prevent sticking. After about 2 to 2 ½ hours, check for doneness. The macaroni should be tender, and the cheese sauce should be thick and creamy.

Step 4: Add Protein (Optional)

If using chicken or beef, stir it into the mac and cheese during the last 15 minutes of cooking. This allows the flavors to blend without overcooking the protein.

Step 5: Serve and Garnish

Once the mac and cheese reaches the perfect consistency, give it one final stir, then serve immediately. Garnish with chopped chives for a pop of color and freshness.

Beginner Tips and Notes

Even though this recipe is straightforward, a few extra tips can help ensure success:

Troubleshooting Common Issues

• Mac and Cheese is Too Thick: If the sauce thickens too much, stir in a small amount of warm milk or half-and-half to loosen it before serving.
• Pasta is Overcooked: Check the macaroni towards the two-hour mark. If it’s tender earlier than expected, reduce the heat to “Keep Warm” or turn off the slow cooker.
• Cheese is Clumping: Always use freshly grated cheese, as bagged pre-shredded cheese contains anti-clumping agents that prevent smooth melting. Stirring every 30 minutes also helps distribute the heat evenly.

Efficient Meal Prep Tips

• Pre-Grate Cheese in Advance: To save time, grate the cheese the night before and store it in an airtight container in the refrigerator.
• Use a Liner for Easy Cleanup: Slow cooker liners can make cleanup effortless, as cheese sauces tend to stick to the pot.
• Double the Recipe for a Crowd: If serving a large group, you can double the ingredients, but be sure to use a larger slow cooker or extend the cooking time slightly.

Serving Suggestions

Mac and cheese is a rich dish that pairs well with a variety of sides. Here are some ideas to round out your meal:

Side Dishes

• Roasted Vegetables: Roasting broccoli, Brussels sprouts, or carrots adds a delicious contrast to the creamy pasta.
• Fresh Salad: A crisp green salad with a tangy vinaigrette balances the richness of the cheese sauce.
• Garlic Bread: Buttery, toasted garlic bread complements the cheesy flavors perfectly.

Flavor Enhancements

If you want to take this dish to the next level, consider these add-ins:

• Spices: A dash of smoked paprika or cayenne pepper can add depth to the flavor.
• Crunchy Topping: Before serving, sprinkle toasted breadcrumbs or crushed crackers on top for added texture.
• Herbs: Fresh thyme, parsley, or basil can add a burst of freshness.

Storage and Reheating Tips

Mac and cheese stores well, making it a great option for leftovers.

Refrigeration

Store leftover mac and cheese in an airtight container in the refrigerator for up to 4 days.

Reheating

To reheat, add a splash of milk to loosen the sauce and warm it over low heat on the stovetop, stirring frequently. If using a microwave, heat in short intervals, stirring between each to prevent uneven heating.

Freezing

For longer storage, freeze portions in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating.
