Five-can casserole opens five pantry cans and bakes them into a quick, easy family dinner. This protein-packed, budget-friendly shortcut meal is proof that great comfort food doesn't need complicated ingredients.
Preheat your oven to 375°F for even baking and set a rack in the center position.
Open and drain mixed vegetables, black beans, and chicken, then add all five canned ingredients to a large mixing bowl.
Add dried onion flakes, garlic powder, and black pepper; gently stir to evenly combine and ensure seasoning is distributed.
Pour mixture into a lightly greased 9x13-inch baking dish, spreading it to an even layer.
Top evenly with shredded cheddar cheese, then bake uncovered for 25–30 minutes until hot, bubbly, and the cheese is golden; check at 25 minutes to prevent overbrowning.
Allow the casserole to cool for 5 minutes before serving to help it set and hold its shape.
