The Easiest, Creamiest Mac and Cheese Ever
Macaroni and cheese is the undisputed king of comfort food. It’s the dish we craved as kids and the one we turn to for a taste of home as adults. I’ve spent years perfecting my mac and cheese, and I can tell you this crockpot mac and cheese is the ultimate hands-off version.

- Insanely Creamy Texture: The combination of evaporated milk and whole milk creates a super stable, ultra-creamy sauce that resists breaking or becoming greasy. It’s pure, velvety perfection.
- Set-It-and-Forget-It: With only 10 minutes of prep, you can toss everything in the crockpot and walk away. It’s the perfect side dish for holidays like Thanksgiving or for any busy weeknight.

Ingredients for Crockpot Mac and Cheese
The secret to the best mac and cheese is using simple, high-quality ingredients. Here’s what you’ll need and why:
The Foundation
- Elbow Macaroni: The classic shape for a reason! The tubes catch all the delicious sauce. Do not use pre-cooked pasta; the magic of this recipe is cooking it from dry.
- Butter: Provides richness and flavor, giving the sauce a silky mouthfeel. Use unsalted so you can control the salt level.
The Creamy Sauce
- Evaporated Milk: This is the non-negotiable secret ingredient! Evaporated milk has less water and higher protein, which acts as an emulsifier and prevents the cheese sauce from curdling or becoming grainy.
- Whole Milk: Adds the necessary liquid for the pasta to cook and contributes to the overall creaminess. Avoid skim milk, as the fat content is crucial for the best texture.
- Sharp Cheddar Cheese: Provides that classic, tangy mac and cheese flavor. For the best melt, buy a block and shred it yourself. Pre-shredded cheeses contain anti-caking agents that can make the sauce gritty.
- Monterey Jack Cheese: This is a master melter! It doesn’t have a strong flavor but provides an incredible, gooey, cheesy pull that complements the sharp cheddar perfectly.
The Seasonings
- Salt and Black Pepper: Essential for enhancing all the other flavors.
- Dry Mustard Powder: Another secret weapon! It won’t make the dish taste like mustard, but it elevates the cheese flavor and adds a subtle, bright tang that cuts through the richness.

Step-by-Step Instructions
Grate the sharp cheddar and Monterey Jack cheeses from blocks. This is key for a smooth, creamy sauce.

Add all ingredients to a 6-quart slow cooker: uncooked pasta, cheeses, evaporated milk, whole milk, butter, and seasonings.

Stir everything together thoroughly, making sure the pasta is completely coated by the liquids and cheeses.

Cover and cook on LOW for 1.5 to 2.5 hours. Cooking times can vary, so check early to prevent overcooking.

Creamy Crockpot Mac and Cheese (So Easy!)
Equipment
- 6-quart slow cooker, box grater, mixing spoon, measuring cups and spoons
Ingredients
Instructions
- 1
Lightly grease the insert of a 6-quart slow cooker with non-stick spray or butter.
- 2
Add all ingredients to the slow cooker: the uncooked macaroni, shredded cheddar, shredded Monterey Jack, evaporated milk, whole milk, cubed butter, salt, pepper, and dry mustard powder.
- 3
Stir everything together thoroughly until the pasta is fully coated and the ingredients are well combined.
- 4
Secure the lid and cook on LOW for 1.5 to 2.5 hours. Slow cooker temperatures can vary, so it's important to start checking for doneness early.
- 5
Stir the mac and cheese well after the first hour to prevent sticking and ensure the pasta cooks evenly in the sauce.
- 6
The mac and cheese is done when the pasta is tender (al dente) and the sauce is thick, creamy, and has fully melted. Be careful not to overcook, or the pasta can become mushy and the sauce may become grainy.
- 7
Give it one final stir, taste for seasoning, and add more salt if needed. Serve immediately while hot and bubbly.
Notes
Shred your own cheese! Pre-shredded cheese contains anti-caking agents that result in a gritty sauce. For the creamiest result, always buy cheese in a block and grate it yourself.
All slow cookers cook differently. Some run hotter than others. Check your mac and cheese at the 1.5-hour mark to gauge progress. Overcooking is the number one reason for grainy mac and cheese.
To reheat leftovers, place them in a saucepan over low heat with a splash of milk. Stir gently until warm and creamy again.
Pro Tips for Perfect Crockpot Mac and Cheese
Follow these tips to guarantee the creamiest, dreamiest mac and cheese every time:
- Shred Your Own Cheese: I can’t stress this enough! Pre-shredded cheese is coated in starches like potato starch or cellulose to prevent clumping. These additives can make your sauce grainy. A box grater and a block of cheese are your best friends here.
- Don’t Overcook the Pasta: Slow cookers vary in temperature. Start checking your mac and cheese at the 1.5-hour mark. The pasta is done when it’s tender but still has a slight bite (al dente). Mushy pasta will ruin the dish.
- Stir Halfway Through: A quick stir about an hour into cooking prevents the pasta from sticking to the bottom and ensures everything cooks evenly.
- Use Room Temperature Dairy: If you have time, let your milk sit out for 20-30 minutes before adding it. This helps prevent the sauce from breaking, although the evaporated milk makes this recipe very forgiving.
- Grease the Slow Cooker: Lightly spray the inside of your crockpot with non-stick spray or rub it with butter to make cleanup a breeze.
Serving Suggestions & Variations
This crockpot mac and cheese is a fantastic canvas for creativity. Here are some ways to serve and customize it:
Delicious Toppings:
- Toasted Panko breadcrumbs with melted butter for a crunchy topping.
- Crumbled crispy bacon and chopped chives.
- A drizzle of buffalo sauce and blue cheese crumbles for a spicy kick.
- Pulled pork or brisket for a hearty main course.
Flavor Variations:
- Smoked Mac and Cheese: Use smoked cheddar or Gruyère for a deep, smoky flavor.
- Three-Cheese Blend: Swap the Monterey Jack for a mix of Gruyère and fontina for a nuttier, more complex taste.
- Spicy Version: Add a pinch of cayenne pepper or a diced jalapeño with the other ingredients.
Storage and Reheating Instructions
Storing Leftovers: Allow the mac and cheese to cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days.
Best Reheating Method: The sauce will thicken considerably in the fridge. To reheat, place the desired portion in a saucepan over low heat. Add a splash of milk (about 1 tablespoon per cup of mac and cheese) and stir gently until it’s heated through and creamy again. Avoid the microwave if possible, as it can make the sauce oily.
Freezing Instructions: I do not recommend freezing this recipe. Dairy-based sauces tend to separate and become grainy upon thawing, altering the creamy texture that makes this dish so special.
