Preheat the oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat.
Add diced onion and cook for 3-4 minutes until softened.
Add minced garlic and cook for 1 minute until fragrant.
Add ground beef to the skillet and cook, breaking it apart with a spoon, until browned and cooked through, about 6-8 minutes.
Drain excess fat from the skillet.
Stir in frozen corn, black beans, diced tomatoes, tomato sauce, ground cumin, chili powder, smoked paprika, salt, and black pepper.
Simmer the mixture for 5 minutes, stirring occasionally.
In a 9×13 inch (23×33 cm) baking dish, spread half of the crushed tortilla chips evenly on the bottom.
Spoon half of the beef mixture over the tortilla chips layer.
Sprinkle half of the shredded cheddar cheese over the beef layer.
Repeat the layers with the remaining crushed tortilla chips, beef mixture, and shredded cheddar cheese.
Bake uncovered in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
Remove from oven and let cool for 5 minutes before serving.
