Pre-heat oven to 350°F.
In a large pot of salter water, boil the spaghetti until al dente; drain and return the pasta to the pot.
Add the remaining ingredients to the pasta, stirring until everything is well combined.
Transfer to a 9 x 13-inch casserole dish.
Sprinkle some cheddar cheese on top and the casserole is ready for the oven.
Bake the dish, uncovered, for about 45 minutes, or until it's hot and bubbly and the cheese is melted on top.
