Slow-Cooker Macaroni and Cheese

Ingredients

1 pound elbow macaroni or small shells1 tablespoon vegetable oil 3 cups boiling water, plus extra as needed2 (12-ounce) cans evaporated milk 2 (11-ounce) cans condensed cheddar cheese soup8 ounces mild cheddar cheese, shredded (2 cups)8 ounces Monterey Jack cheese, shredded (2 cups)1 teaspoon dry mustard Salt and pepper 1 cup bread crumb topping, to taste

Before You Begin

You will need an oval slow cooker for this recipe. For an accurate measurement of boiling water, bring a full kettle of water to a boil and then measure out the desired amount.

Instructions

  1. 1. Line slow cooker with aluminum foil collar and lightly coat with vegetable oil spray. Microwave macaroni and oil in bowl at 50 percent power, stirring occasionally, until macaroni begin to look toasted and blistered, 5 to 8 minutes.
  2. Transfer hot macaroni to prepared slow cooker and immediately stir in 2¾ cups boiling water. Stir in evaporated milk, condensed soup, cheddar, Monterey Jack, mustard, 1 teaspoon pepper, and ½ teaspoon salt. Cover and cook until macaroni are tender, 1 to 2 hours on high.
  3. Discard foil collar. Gently stir remaining ¼ cup boiling water into macaroni until combined. Season with salt and pepper to taste. Adjust consistency with extra boiling water as needed. Sprinkle individual portions with bread-crumb topping, if using. Serve. (Macaroni can be held on warm or low setting for up to 30 minutes.)

Why This Recipe Works

Slow-cooker macaroni and cheese is notoriously finicky—the pasta is usually overcooked and flabby, and the dairy-based sauce breaks and curdles during the long cooking time, resulting in a grainy, separated sauce. We found that toasting our macaroni with a little oil allowed its proteins to set, which prevented excessive swelling. By combining it with boiling water, we could jump-start its cooking and cut down on cooking time. As for the sauce, we found that evaporated milk and condensed cheddar cheese soup, because of their stabilizers, created a creamy base that didn't break. Shredded cheddar ramped up the flavor but brought back some of the graininess. Swapping in some Monterey Jack, which has a creamier texture when melted, produced a rich-tasting sauce with a smooth consistency; some dry mustard boosted the cheesy flavor.
