Million-Dollar Spaghetti

Step 1
Preheat the oven to 350 degrees F (175 degrees C).

Step 2
Bring a large pot of lightly salted water to a boil. Cook spaghetti in boiling water until cooked through but firm to the bite, about 12 minutes. Drain.

Step 3
Heat a large skillet over medium-high heat. Cook and stir beef in the hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease. Transfer to a bowl and mix in spaghetti sauce.

Step 4
Place 1/2 of the butter slices into the bottom of a 9×13-inch casserole dish. Spread 1/2 of the spaghetti into the dish.

Step 5
Mix cottage cheese, cream cheese, and sour cream together in a bowl; spread mixture over spaghetti. Cover with remaining spaghetti and top with remaining slices of butter.

Step 6
Pour ground beef mixture over spaghetti and spread in an even layer.

Step 7
Bake in the preheated oven for 30 minutes. Spread Cheddar cheese on top and continue baking until cheese has melted and is lightly browned, about 15 minutes more.
