Slow Cooker Macaroni and Cheese

A creamy, sharp cheddar mac that cooks entirely in the slow cooker, no boiling the pasta first and no roux to babysit. It is the dish I bring to potlucks because it stays hot and scoopable for hours.

The Story Behind This Recipe

Slow Cooker Macaroni and Cheese started as a "what's actually in the fridge" dinner and quietly turned into something I make on purpose. Somewhere around the third or fourth time, I stopped improvising and started writing it down.

I have made it for a quiet Tuesday and for a table full of people, and it behaves the same either way, which is the highest compliment I give a recipe.

If there is a trick, it is patience with the browning. Every time I have rushed that step, the whole dish came out flatter than it should have.

Variation Ideas

  • Double it and use the leftovers as a filling for wraps or grain bowls.
  • Toss in seasonal vegetables — squash in fall, asparagus in spring.
  • Top with something crunchy: toasted breadcrumbs, nuts or crispy shallots.

Ingredient Substitutions

Butter
Olive oil for savory dishes, or a good vegan stick for baking
Milk
Unsweetened oat or soy milk, which behave closest in cooking
Fresh garlic
1/2 tsp garlic powder per clove, in a pinch
Dijon mustard
Whole-grain mustard, or yellow mustard in a smaller amount

Frequently Asked Questions

How long will this last?

Refrigerate in an airtight container for up to 3 days, or freeze for up to 3 months.

What is the best way to reheat it?

Warm it gently — covered at 300°F or over low heat on the stove with a splash of liquid — until just heated through. Fast, high heat is what dries leftovers out.

Can I make it ahead?

Yes. Prep and refrigerate the components up to a day ahead, then combine and finish just before serving so nothing loses its texture.

It tastes flat — what should I do?

Salt and acid, in that order. A pinch more salt then a squeeze of lemon or splash of vinegar will usually sharpen everything back into focus.
