First things first, get that elbow macaroni going. Boil it in a big pot of salted water, but only for about 3-4 minutes – we're talking really al dente here, almost undercooked. It needs to still be quite firm because it's going to finish cooking in the slow cooker. I always forget to salt the water enough, so don't be like me! Drain it well and give it a rinse with cold water to stop the cooking, then set it aside. This step is critical for preventing mushy Slow Cooker Mac and Cheese.

In a large bowl, whisk together the whole milk, evaporated milk, heavy cream, and cream cheese until it's smooth-ish. Don't worry if the cream cheese is a little lumpy, it'll melt down in the heat. Now, stir in the Dijon mustard, garlic powder, onion powder, smoked paprika, salt, and black pepper. Give it a good whisk until everything is combined. This is where the magic starts to smell really good, even before it hits the slow cooker. I once accidentally added way too much mustard, and let's just say it was… zesty.

Grease your slow cooker insert with a little butter or cooking spray. Now, layer about a third of your grated cheddar, Monterey Jack, and Gruyere cheeses at the bottom. Then, add half of your par-cooked macaroni. Pour about half of the milk mixture over the pasta, and top with another third of the cheese blend. Repeat with the remaining macaroni, milk mixture, and cheese. It should look like a glorious cheesy lasagna, but for Slow Cooker Mac and Cheese!

Cover your slow cooker and cook on LOW for 1.5 to 2 hours. This is where the patience comes in! Resist the urge to peek too often, because every time you lift that lid, you lose heat. The goal here is for the pasta to absorb the creamy sauce and become tender, and for the cheeses to start melting into gooey deliciousness. You'll start smelling that amazing cheesy aroma wafting through your kitchen, and honestly, it's the best kind of aromatherapy.

After about 1.5 hours, give it a gentle stir. The pasta should be mostly tender. Now, add the remaining butter, cut into small pieces, and stir it in. This adds an extra layer of richness and helps the final cheese melt beautifully. If it looks a little thin, don't panic! It will thicken as it cools. Keep the lid on for another 15-30 minutes, or until the cheese is fully melted and the sauce is thick and bubbly. This step is critical for the ultimate Slow Cooker Mac and Cheese.

Once it's ready, give it one last good stir. The Slow Cooker Mac and Cheese should be incredibly creamy, with tender pasta swimming in a rich, cheesy sauce. Taste it and adjust any seasonings if needed – maybe a little more salt or pepper? Ladle it into bowls, and if you're feeling fancy, sprinkle with some fresh chopped parsley. It looks beautiful and adds a fresh counterpoint to all that richness. Enjoy that warm, comforting hug!
