This Crockpot Mac and Cheese is a creamy, comforting side made with tender elbow macaroni, extra-sharp cheddar, American cheese, whole milk, and evaporated milk, all cooked together right in the slow cooker.
When you need a warm, crowd-friendly dish without watching a pot on the stove, this slow cooker mac and cheese fits the occasion beautifully. The pasta cooks directly in the creamy cheese mixture, which keeps prep simple and cuts down on extra pans.
Extra-sharp cheddar gives the sauce plenty of bold cheese flavor, while American cheese helps it melt into a smoother consistency. Evaporated milk adds richness without making the sauce unnecessarily complicated, and a little mustard, garlic, black pepper, and cayenne keeps the flavor balanced.
It is especially useful for holidays, potlucks, family dinners, or any meal where your stovetop is already crowded. Since slow cookers vary quite a bit in temperature, the key is checking the macaroni early and stopping the cooking as soon as the noodles become tender.
Crockpot Mac and Cheese Ingredients
Elbow macaroni: Standard dry elbow macaroni is the right shape for this method because the small noodles cook evenly and hold plenty of creamy cheese sauce.
Extra-sharp cheddar cheese: This is the main source of bold cheddar flavor. Shredding it yourself from a block helps it melt more smoothly than many packaged shredded cheeses.
American cheese: Adds extra creaminess and helps create a cohesive, smooth sauce around the macaroni.
Whole milk: Provides the liquid the pasta needs as it cooks while contributing a rich dairy flavor.
Evaporated milk: Adds concentrated creaminess and gives the finished sauce more body than using regular milk alone.
Butter: Small cubes melt gradually over the pasta, adding richness throughout the slow cooker.
Dry mustard powder: Gives the cheese sauce subtle depth and enhances its savory flavor without making the finished dish taste strongly of mustard.
Garlic powder: Adds a mild savory background note that complements the cheeses.
Black pepper and cayenne: Freshly ground black pepper adds gentle warmth, while just a dash of cayenne gives the sauce a subtle lift.
Salt: Seasons both the pasta and the creamy cheese mixture as they cook together.
Cooking Steps
STEP 1: Coat the inside of a 6-quart slow cooker with nonstick cooking spray. Place the dry elbow macaroni in a colander, rinse thoroughly under cold water, and allow it to drain very well. Removing some of the loose surface starch can help keep the pasta from becoming overly gummy.
STEP 2: Transfer the drained macaroni to the slow cooker. Pour the whole milk and evaporated milk evenly over the pasta, making sure the noodles are well distributed across the bottom.
STEP 3: Add the freshly shredded cheddar and American cheese. Sprinkle in the salt, dry mustard, garlic powder, black pepper, and a small dash of cayenne. Stir thoroughly so the seasonings and cheeses are dispersed throughout the pasta and liquid.
STEP 4: Smooth the macaroni into an even layer, keeping as much of it beneath the liquid as possible. Scatter the small butter cubes across the top, then cover the slow cooker securely.
STEP 5: Cook on low for 1 hour without repeatedly opening the lid. Keeping the cooker covered helps it maintain the steady heat needed to cook the pasta evenly.
STEP 6: After the first hour, remove the lid briefly and stir thoroughly. Scrape gently around the edges and bring the melted cheese, milk, and pasta together into a creamy sauce. Taste one piece of macaroni to check its texture.
STEP 7: If the pasta is still firmer than you prefer, replace the lid and continue cooking on low in 30-minute intervals. Stir and taste after each interval. Once the noodles are tender and coated in a thick cheese sauce, turn off the slow cooker and let the mac and cheese rest for several minutes before serving.
Can you put uncooked pasta directly in a slow cooker?
Yes. This method is specifically designed for dry elbow macaroni to cook directly in the milk and cheese mixture. The important part is using standard pasta rather than quick-cooking noodles and checking it regularly after the first hour so it does not become too soft.
Why is my slow cooker mac and cheese getting thick?
The sauce naturally thickens as the macaroni absorbs liquid and releases starch. It will also become thicker as it sits after cooking. If yours becomes thicker than you like, gently stirring in a small splash of warm whole milk can loosen the sauce before serving.
Should I rinse macaroni before slow cooking it?
For this particular preparation, yes. A quick cold-water rinse removes some loose starch from the surface of the dry pasta. Be sure to drain the noodles thoroughly afterward so you do not introduce unnecessary water into the cheese sauce.
Can I use pre-shredded cheese?
You can, but freshly shredded cheese generally produces the smoother result. Packaged shredded cheeses often contain ingredients that keep the pieces from clumping in the bag, and those can also affect how smoothly the cheese melts into a sauce.
How do I keep crockpot mac and cheese from overcooking?
Begin checking the pasta after its first hour on low. Slow cookers can heat very differently, so there is no single exact finishing time that works for every model. Once the noodles are tender, stop the cooking rather than leaving the mac and cheese on heat for an extended period.
Helpful Tips
- Shred the cheese yourself. Block cheddar and block-style American cheese melt more evenly and give the sauce a smoother texture.
- Watch the pasta closely near the end. The difference between tender and overly soft macaroni can happen quickly in a hot slow cooker, especially after the first hour.
- Keep the lid closed when possible. Stir when needed, but work quickly so the cooker does not lose too much heat every time you check the noodles.
Serving Ideas for Crockpot Mac and Cheese
A creamy bowl of macaroni and cheese can work as either a substantial side dish or part of a larger comfort-food meal.
Roasted or grilled chicken: A simply seasoned chicken dish provides a savory main course that pairs naturally with the creamy pasta.
Roasted vegetables: Broccoli, Brussels sprouts, green beans, or other roasted vegetables add a contrasting texture and keep the meal from feeling too heavy.
Barbecue-style mains: Pulled pork, ribs, or other smoky barbecue dishes work especially well alongside rich cheddar mac and cheese.
Storage & Reheating
Allow leftovers to cool before transferring them to an airtight container. Refrigerate the mac and cheese for up to 3 to 4 days.
Because the pasta continues absorbing sauce as it rests, refrigerated leftovers will usually be considerably thicker than the freshly cooked dish. When reheating, add a small splash of milk and stir gently to restore some of the original creaminess.
For individual portions, microwave the macaroni in short intervals, stirring between each round so it reheats evenly. Larger portions can be warmed slowly on the stovetop over low heat with a little additional milk.
You can also freeze leftovers for up to about 2 months, although the texture of both the pasta and dairy-based sauce may be softer after thawing. For the most appealing consistency, refrigerating and reheating within a few days is preferable.
The most important part of making this slow cooker mac and cheese is simply paying attention toward the end of cooking. Once the elbows are tender, the cheddar and American cheese have melted together, and the sauce has reached a creamy consistency, it is ready to serve. Give it a brief rest, stir once more, and bring it to the table while it is still hot and wonderfully creamy.
Crockpot Mac and Cheese
Ingredients
- 12 fluid ounces evaporated milk
- 1/2 teaspoon dry mustard powder
- 1 cup American cheese freshly shredded from a block
- 1/4 cup butter cut into small cubes
- 1 teaspoon salt
- 2 1/2 cups whole milk
- A dash of cayenne pepper adjusted to taste
- 1 pound dry elbow macaroni
- 1/4 teaspoon garlic powder
- 3 cups extra-sharp cheddar cheese freshly grated from a block
- 1/2 teaspoon freshly ground black pepper
Instructions
- Coat the inside of a 6-quart slow cooker with nonstick cooking spray. Place the uncooked elbow macaroni in a colander and rinse it thoroughly beneath cold running water. Drain well before proceeding. Rinsing away some of the surface starch helps reduce gumminess as the pasta cooks.
- Transfer the rinsed and thoroughly drained macaroni to the prepared slow cooker. Pour in the whole milk and evaporated milk.
- Add the freshly shredded extra-sharp cheddar and American cheese. Season the mixture with salt, black pepper, dry mustard, garlic powder, and a dash of cayenne pepper according to taste.
- Stir everything thoroughly so the cheese, seasonings, and liquids are evenly distributed. Arrange the macaroni so that as much of the pasta as possible remains beneath the liquid for more consistent cooking.
- Distribute the cubed butter evenly across the surface of the macaroni mixture. Cover the slow cooker securely with its lid and cook on the low setting for 1 hour.
- After the first hour, briefly uncover the slow cooker and stir the macaroni well, bringing the melted cheese and sauce together while redistributing the pasta. Replace the lid promptly to minimize heat loss.
- Test the macaroni for tenderness. Some slow cookers may cook the pasta sufficiently within the first hour. If the noodles are still too firm, cover the cooker again and continue cooking on low.
- Check and stir the macaroni every 30 minutes until the pasta reaches the desired tenderness. Tasting a piece during each check can help prevent the noodles from becoming overcooked.
- When the macaroni is tender and the cheese sauce has developed a thick, creamy consistency, remove the lid. Allow the finished mac and cheese to stand for a few minutes so the sauce can thicken slightly before serving.
- Serve while hot. If desired, finish each serving with a small additional sprinkling of cheddar cheese.
Notes
- For the smoothest melting texture, shred both cheeses directly from blocks rather than using pre-shredded cheese. Block-style American cheese is preferable to processed cheese slices.
- Standard elbow macaroni is recommended rather than quick-cooking or gluten-free varieties. Barilla elbow macaroni was preferred in the original preparation.
- Whole milk provides the richest result; Organic Valley whole milk was specifically preferred in the original recipe.
- Boar’s Head block-style American cheese was noted as a preferred option.
- Keep the lid removal as brief as possible when stirring and checking the pasta so the slow cooker retains its heat.
