Last Thanksgiving, I was tasked with bringing a side dish to my sister's house. You know how it is – everyone's got their "specialty" and mine has always been... well, let's just say ordering really good takeout. But this year, I was determined to actually cook something that wouldn't embarrass me in front of the family.
My brother-in-law Jake is one of those guys who thinks he's Gordon Ramsay because he can grill a decent burger. The man has never met a homemade dish he couldn't critique. So when I announced I was making Crockpot Mac and Cheese, he actually laughed. "Store-bought sauce in a slow cooker? Real original, Dave."
Well, guess who went back for thirds? That's right – Mr. Food Critic himself practically licked the crockpot clean. This recipe isn't just your average throw-everything-together mac and cheese. It's the result of me obsessing over dozens of recipes, reading thousands of reviews, and basically turning my kitchen into a cheese laboratory for three weeks straight.
Why You'll Love This Recipe
- Ridiculously creamy – I'm talking restaurant-quality smooth without any of that grainy, separated mess
- Foolproof method – Even my neighbor Bob (who once burned water) nailed this on his first try

- Feeds a crowd – Perfect for potlucks, game day, or when the kids bring half the neighborhood home
Ingredients
For the pasta:
- 1 pound elbow macaroni (or cavatappi if you're feeling fancy)
- 1 tablespoon salt (for pasta water)
For the cheese sauce:
- 16 oz sharp cheddar cheese, freshly grated from block
- 8 oz American cheese from deli counter, cubed
- 12 oz evaporated milk
- 1½ cups whole milk
- ½ cup mayonnaise (the secret weapon!)
- 4 tablespoons butter
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon dry mustard powder
- ¼ teaspoon paprika
How to Make the Best Crockpot Mac and Cheese
1. Prepare the pasta: Cook your elbow macaroni in heavily salted water for 2 minutes LESS than the package directions say. I know it sounds weird, but trust the process here. The pasta should be firm but not crunchy – think of it as pasta that's having an identity crisis. Drain and rinse with cold water to stop the cooking process. My wife always skips this step and wonders why her pasta turns to mush... some battles aren't worth fighting.
2. Prep the cheese: Here's where most people mess up – they grab that pre-shredded stuff from a bag. Don't do it! Grate your cheddar cheese from a block while it's cold, then let it come to room temperature. Cube the American cheese into small pieces. Those pre-shredded cheeses have anti-caking agents that'll make your mac and cheese grainier than a badly dubbed foreign film.
3. Layer the slow cooker: Spray a 4-6 quart slow cooker with cooking spray. Add the cooked pasta to the bottom. It's gonna look lonely in there, but don't worry – it's about to make some cheesy friends.
4. Create the base: In a large bowl, whisk together evaporated milk, whole milk, mayonnaise, melted butter, salt, pepper, garlic powder, onion powder, dry mustard, and paprika until smooth. This is where the magic happens – you're basically creating liquid gold here.
5. Combine ingredients: Pour the milk mixture over the pasta and stir gently. Add half of the cheddar cheese and all of the American cheese, stirring carefully to distribute. It's like tucking your pasta into a cheesy blanket.
6. Cook low and slow: Cover and cook on LOW for 1½ hours. And here's the hard part – DO NOT lift the lid during this time. I know you want to peek. My dad can't help himself and lifts the lid every 20 minutes like he's checking on a sleeping baby. Resist the urge!
7. Final cheese addition: After 1½ hours, add the remaining cheddar cheese and stir gently. Cook for an additional 30 minutes on LOW. This is when you'll start smelling heaven wafting from your kitchen.
8. Finish and serve: Check that pasta is tender and cheese is fully melted. Switch to warm setting if not serving immediately, but serve within 2 hours for best texture. Any longer and it starts getting weird.
Recipe Variations and Substitutions
Want to jazz things up? Here are some tricks I've picked up:
- Bacon lovers: Crumble in some cooked bacon during the last 30 minutes
- Spice it up: Add diced jalapeños or a dash of hot sauce
- Veggie boost: Throw in some steamed broccoli or cauliflower
- Different cheeses: Try mixing in some smoked gouda or gruyere – just keep the American cheese for that creamy base
- Protein power: Leftover pulled pork or rotisserie chicken works great mixed in
Serving Suggestions
This mac and cheese is like that friend who gets along with everyone:
- BBQ night: Pairs perfectly with pulled pork, fried chicken, or grilled sausages
- Balance the richness: Serve with a crisp green salad with vinaigrette or steamed broccoli
- Go full Southern: Cornbread and coleslaw make this a proper comfort food feast
- Game day: Perfect alongside wings and beer (obviously)
Storing Instructions
Let's be real – there usually aren't leftovers when I make this. But if you somehow have restraint, store it in the refrigerator for up to 4 days. Reheat gently in the microwave with a splash of milk to bring back that creamy texture. You can also reheat it in the oven at 350°F covered with foil.
Don't freeze it though – the texture gets weird and nobody wants chunky mac and cheese. Trust me on this one.
FAQ
Q: Can I use pre-shredded cheese? A: Please don't. I tried this once to save time and ended up with something that looked like cheese soup with pasta floating in it. The anti-caking agents in pre-shredded cheese will ruin your day and your mac and cheese.
Q: What if I don't have evaporated milk? A: You can substitute with heavy cream, but use about 8 oz instead of 12 oz. The evaporated milk is really the MVP here because it's been pre-cooked and won't curdle on you.
Q: Can I make this ahead of time? A: Absolutely! Cook your pasta and grate your cheese the night before. Store them separately in the fridge, then combine everything when you're ready to cook. Just add maybe 15 minutes to the cooking time if everything's cold.
Q: My slow cooker runs hot – what should I do? A: Every slow cooker has its own personality. Start checking at 1½ hours and adjust accordingly. My mom's ancient Crockpot from the 80s cooks everything in half the time – that thing could probably power a small city.
Q: Can I double this recipe? A: Sure can! Use a 6+ quart slow cooker and only increase the cooking time by about 15-30 minutes. Any bigger and you might need to consider just making two batches.
Q: What's the deal with the mayonnaise? A: I know it sounds weird, but mayo is basically eggs and oil, which makes it a natural emulsifier. It keeps everything smooth and creamy without adding any mayo flavor. My teenage daughter was horrified when she found out, but she still ate three bowls.
