Step 1

Heat a large skillet over medium-high heat. Cook and stir ground beef in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease. Add salsa, corn, and taco seasoning. Season meat sauce with salt and pepper.

Step 2

Preheat the oven to 375 degrees F (190 degrees C).

Step 3

Fill a large pot with lightly salted water and bring to a rolling boil. Stir in pasta and return to a boil. Cook pasta uncovered, stirring occasionally, until tender yet firm to the bite, 10 to 12 minutes. Drain.

Step 4

Combine the meat sauce, pasta, Colby-Jack cheese, and green onions in a 9x13-inch casserole dish. Sprinkle Cheddar cheese on top.

Step 5

Bake in the preheated oven until cheese is melted, about 25 minutes.
