Start by heating your skillet over medium-high heat. Add the ground beef and cook until it’s nicely browned, breaking it apart as it cooks. Once there’s no pink left, stir in the diced onions and let them soften for a few minutes. Drain any excess grease before moving on.
Next, pour in the Manwich sauce, diced tomatoes (with their juices), and chicken broth. Stir everything together and bring it to a gentle boil. Add the uncooked farfalle pasta, then reduce the heat to medium and let it simmer for about 15 minutes, stirring occasionally so the pasta doesn’t stick to the bottom.
When the pasta is tender, stir in the corn and cubed Velveeta. Cover the skillet for a few minutes to let the cheese melt smoothly into the sauce. Once melted and creamy, transfer everything to your casserole dish, sprinkle shredded cheddar cheese evenly over the top, and bake at 375°F for about 15 minutes until golden and bubbly.
