  • 3 cups shredded mild or sharp cheddar cheese, divided

Ingredient Notes

Macaroni: Use uncooked elbow macaroni.

Ground beef: Use 80% to 90% lean ground beef.

Tomato pasta sauce: Use your favorite jarred sauce.

Cheddar cheese: Use mild or sharp cheddar. Divide into 2 cups and 1 cup.

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Lightly grease a 2 to 3-quart oval baking dish.

Step 2: Cook the Macaroni

Bring a large pot of salted water to a boil. Add the elbow macaroni and cook until just shy of al dente, about 1 to 2 minutes less than the package directions. Drain well.

Step 3: Brown the Beef

In a large skillet over medium heat, cook the ground beef until fully browned. Drain off excess fat.

Step 4: Add the Sauce

Pour the tomato pasta sauce into the skillet with the beef. Stir to combine and simmer for 2 to 3 minutes.

Step 5: Combine Everything

In a large bowl, combine the drained macaroni with the beef and sauce mixture. Add 2 cups of the shredded cheddar cheese and stir until evenly distributed.

Step 6: Transfer to Baking Dish

Spoon the mixture into the prepared baking dish, smoothing it into an even layer. Sprinkle the remaining 1 cup of shredded cheddar cheese over the top.

Step 7: Bake

Bake for 25 to 30 minutes, until the casserole is bubbling and the cheese is melted and golden.

Step 8: Rest and Serve

Let the casserole rest for 5 to 10 minutes before serving.
