How to Make Weight Watchers Macaroni and Cheese Casserole

Step 1: Preheat the Oven

Heat oven to 400ºF (200ºC). Lightly coat a 9 x 9-inch baking dish or 2-quart casserole dish with nonstick cooking spray.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil. Add elbow macaroni and cook until just tender, about 7 minutes. Drain well.

Step 3: Make the Creamy Mixture

Return the pasta to the pot. Stir in the cream soup, fat-free mayonnaise, shredded cheese, red pepper, and pimentos. Mix until the cheese melts and the sauce becomes smooth and creamy.

Step 4: Assemble the Casserole

Transfer the mixture to the prepared baking dish. Sprinkle the crushed whole-wheat crackers evenly on top.

Step 5: Bake

Bake uncovered for 20–25 minutes, or until the casserole is golden and bubbling around the edges.

Step 6: Serve

Allow the casserole to cool slightly. Cut into 6 portions and enjoy warm.

Expert Tips

• Stir in steamed broccoli florets or sliced green onions for extra volume—both are zero points.
• Bake in individual ramekins for portion control (reduce bake time to about 20 minutes).
• Swap the crackers for seasoned panko crumbs for a lighter, crispier topping.

Variations & Creative Twists

• Add lean protein like diced chicken breast or ground turkey.
• Stir in dry mustard or onion powder for extra depth of flavor.
• Use a blend of low-fat cheddar and reduced-fat Monterey Jack for extra creaminess.
• Swap elbow pasta for whole-wheat rotini or gemelli for extra texture.
