Ingredients
Gathering these simple ingredients is the first step toward a pot of irresistible slow cooker mac and cheese.
| Ingredient | Quantity | Notes |
|---|---|---|
| Elbow macaroni | 1 pound (16 ounces) | Uncooked |
| Cheddar cheese | 3 cups | Shredded, sharp or medium |
| Milk | 3 cups | Whole milk recommended for creaminess |
| Butter | 1/2 cup (1 stick) | Unsalted |
| Flour | 1/4 cup | All-purpose |
| Eggs | 2 large | Lightly beaten (optional, for a richer finish) |
| Salt | 1 teaspoon | Or to taste |
| Black pepper | 1/2 teaspoon | Freshly ground, or to taste |
The star of this dish is, of course, the cheese. A good sharp cheddar provides a wonderful depth of flavor, but feel free to mix in other melting cheeses like Gruyere or Monterey Jack for added complexity. The butter and flour form a basic roux, which is essential for creating a smooth, thick sauce that holds the cheese beautifully. Whole milk contributes to the overall creaminess, making the mac and cheese luxuriously rich.
Step-by-Step Instructions
Follow these simple steps to create your best slow cooker mac and cheese.
Prepare the Slow Cooker and Ingredients
- Lightly grease the inside of your slow cooker with butter or cooking spray to prevent sticking.
- In a large bowl, whisk together the lightly beaten eggs (if using), milk, salt, and pepper.
Make the Cheese Sauce Base
- In a separate medium saucepan over medium heat, melt the butter.
- Whisk in the flour until smooth and cook for about 1 minute, stirring constantly, to create a paste (roux).
- Gradually whisk in the milk mixture from the bowl, bit by bit, until fully incorporated and smooth.
- Cook, stirring frequently, until the sauce begins to thicken slightly, about 5-7 minutes. Do not boil.
- Remove the saucepan from the heat. Gradually stir in the shredded cheddar cheese until it is melted and the sauce is smooth and creamy.
Combine and Cook
- Add the uncooked elbow macaroni directly into the prepared slow cooker.
- Pour the cheese sauce evenly over the macaroni. Stir gently to ensure all the pasta is coated.
- Cover the slow cooker with the lid.
- Cook on High for 1.5 to 2 hours, or on Low for 3 to 4 hours, stirring gently every hour or so to prevent sticking and ensure even cooking. The macaroni should be tender and the sauce creamy.
Serve
- Once cooked through and creamy, taste and adjust seasoning with additional salt and pepper if needed.
- Serve hot directly from the slow cooker.
Granny Tips for Perfect Results
Here are a few of my tried-and-true tips to help you achieve the creamiest, most delicious slow cooker mac and cheese every time.
- Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can make your sauce a bit grainy. Shredding cheese from a block will give you a smoother, silkier sauce.
- Don’t Overcook the Macaroni: Pasta can become mushy if overcooked. Keep a close eye on it during the last hour of cooking, especially if using the High setting. This recipe is meant for everyday comfort and is not a replacement for medical advice.
- Adjust Liquid as Needed: If the mac and cheese seems too thick halfway through cooking, you can add a little more milk or even a splash of water to reach your desired consistency.
- Stir Gently and Frequently: While the slow cooker does the work, giving the mac and cheese a gentle stir every hour helps to prevent the bottom from sticking or becoming too stiff and ensures the sauce remains evenly distributed.
- Use a Good Quality Cheddar: The flavor of your cheese is paramount. A good sharp cheddar will provide a more robust and satisfying cheesy taste than a mild one.
- Consider a Roux: Making a quick roux (cooking flour and butter together) before adding the milk helps to thicken the sauce properly and gives it a smoother texture, preventing a “watery” cheese sauce.
Common Mistakes to Avoid
Even with a simple recipe, a few common missteps can affect the final outcome of your slow cooker mac and cheese.
- Mistake: Using cold dairy. Using cold milk and eggs directly from the refrigerator can cause the cheese sauce to seize up or become unevenly heated. Fix: Ensure your milk and eggs are at room temperature before adding them to the sauce base, or warm the milk gently before incorporating it.
- Mistake: Adding uncooked pasta without enough liquid. The pasta needs liquid to cook properly. Not having enough milk or sauce can result in undercooked or dry pasta. Fix: Ensure you have the full amount of liquid specified, and consider adding a little extra milk if the mixture seems dry before cooking.
- Mistake: Overcooking the pasta leading to mush. Leaving the mac and cheese in the slow cooker for too long, especially on High, can turn tender pasta into a mushy mess. Fix: Start checking for doneness about 30 minutes before the minimum cook time suggests, and remove from heat as soon as the pasta is tender.
- Mistake: Not stirring the sauce enough. Failing to stir the cheese sauce while it thickens can lead to a lumpy or scorched bottom. Fix: Whisk continuously when making the roux and sauce on the stovetop, and provide gentle stirs every hour in the slow cooker.
Variations and Substitutions
This classic recipe is wonderful as is, but it’s also a great base for creative twists and personal preferences.
| Variation or Ingredient | Substitution | Result |
|---|---|---|
| Cheddar Cheese | Mix Gruyere, Monterey Jack, or Colby for 1/3 of the cheddar. | Adds nutty or milder flavor notes. |
| Milk | Use half-and-half for extra richness, or a dairy-free milk like unsweetened almond or oat milk. | Richer sauce or a dairy-free option. Note that dairy-free milks may result in a thinner sauce. |
| Butter | Use a good quality dairy-free butter alternative. | Dairy-free option. |
| Pasta Shape | Use shells, rotini, or penne instead of elbow macaroni. | Slightly different texture and sauce-holding capacity. Ensure pieces aren’t too large to cook evenly in the slow cooker. |
| Additions | Stir in cooked broccoli florets, peas, or diced ham during the last 30 minutes of cooking. | A more complete meal with added vegetables or protein. |
Serving Suggestions and Pairings
This comforting slow cooker mac and cheese is hearty enough to be the star of your meal, but it also makes a fantastic side dish.
Serve it piping hot straight from the slow cooker for maximum coziness on a chilly evening. It pairs beautifully with many dishes. For a simple family dinner, serve it alongside a fresh Easy Italian Antipasto Salad for a balanced meal. It’s also a wonderful accompaniment to grilled chicken or pork tenderloin. For a more casual gathering, consider serving it as part of a buffet with other comfort classics. A sprinkle of fresh parsley or chives just before serving adds a touch of color and freshness.
Storage and Reheating
Leftover slow cooker mac and cheese is a treasure, perfect for enjoying later.
| Method | Duration | Instructions |
|---|---|---|
| Refrigerator | 3-4 days | Store in an airtight container in the refrigerator. The sauce may thicken considerably as it cools. |
| Freezer | 1-2 months | Freezing can sometimes affect the creaminess of dairy-based sauces. Store in a freezer-safe container or bag. |
Reheating: For best results, reheat gently on the stovetop over low heat, adding a splash of milk or water to loosen the sauce. You can also reheat in the microwave, stirring halfway through. If reheating from frozen, thaw in the refrigerator overnight before reheating.
