Preheat your oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat. Add diced onions and cook until softened, about 3-4 minutes.
Add minced garlic to the skillet and cook for an additional minute, stirring frequently.
Add ground beef to the skillet and cook until browned, breaking it apart with a spatula, about 6-8 minutes. Drain any excess grease.
Season the beef mixture with salt, black pepper, and paprika. Mix well and transfer the cooked meat to the bottom of a lightly greased 9x13-inch baking dish, spreading it out to form an even layer.
If preparing mashed potatoes from scratch, boil peeled and cubed potatoes in salted water until tender, about 15 minutes. Drain, then mash with milk and butter until smooth. Season with salt to taste.
Spread the mashed potatoes over the meat layer in the baking dish, smoothing it into an even layer with a spatula.
In a medium bowl, mix the frozen mixed vegetables with half of the shredded cheddar cheese.
Spread the vegetable and cheese mixture over the mashed potato layer in the baking dish.
Sprinkle the remaining shredded cheddar cheese evenly over the top.
Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbling.
Remove the casserole from the oven and let it sit for 5 minutes before serving. Enjoy!
