This crockpot Velveeta mac and cheese is creamy, rich, and made to feed a crowd without babysitting the stove. Elbow macaroni cooks right in the slow cooker with half and half, butter, Dijon mustard, sharp cheddar, and Velveeta for a smooth, spoonable mac and cheese that holds up well for parties, holidays, and potlucks.
Get prepped: Lightly grease the slow cooker with cooking spray. Measure out all ingredients. Cube the Velveeta and shred the cheddar if needed.
Add the pasta: Add the dry 12 ounces elbow macaroni to the slow cooker and spread it into an even layer.
Add the liquids and seasonings: In a bowl, whisk together 3 cups half and half, 4 tablespoons butter, 1 teaspoon Dijon mustard, 1 teaspoon salt, and 1/2 teaspoon pepper until smooth. Pour the mixture over the pasta and stir so the noodles are mostly covered and evenly coated.
Add the cheese: Scatter 2 cups sharp cheddar cheese over the top, then add12 ounces Velveeta cheese (cubed). Gently stir just enough to distribute the cheese.
Cook: Cover and cook on low for 2 to 2 1/2 hours, stirring once halfway through, or on high for 1 to 1 1/2 hours, stirring once or twice. The mac and cheese is done when the pasta is tender and the sauce is smooth and creamy.
Finish: Give everything a good final stir before serving. If it thickens as it sits, stir in a splash of half and half to loosen it back up.
Notes
Cook on low for the creamiest texture.
Stir once halfway through cooking.
Shred your own cheddar for smoother melting.
Keep extra half and half nearby to loosen the sauce.
