Preheat your oven to 375°F (190°C).
In a large skillet, heat olive oil over medium heat. Add diced onion and cook until softened, about 3-4 minutes. Add minced garlic and cook for another minute.
Add ground beef to the skillet and cook until browned, breaking it up with a wooden spoon. Sprinkle with salt and black pepper.
Stir in tomato sauce and let it simmer for 5 minutes. Set aside.
Meanwhile, place peeled and cubed potatoes in a large pot of salted water. Bring to a boil and cook until tender, about 12-15 minutes.
Drain the potatoes and mash them in the pot. Add butter and milk, stirring until creamy. Season with a pinch of salt, then set aside.
In another skillet, cook the frozen mixed vegetables over medium heat until heated through. Remove from heat and mix in 1 cup of shredded cheddar cheese and half of the sliced green onions.
Now it’s time to assemble. Spread the ground beef mixture evenly in the bottom of a 9x13-inch baking dish.
Layer the mashed potatoes on top of the beef mixture, smoothing them out with a spatula.
Spread the vegetable and cheese mixture over the mashed potatoes as the final layer.
Sprinkle the remaining 1 cup of shredded cheddar cheese on top.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbling and the cheese is melted and golden.
Remove from the oven and let it rest for 5 minutes before serving. Garnish with the remaining green onions, if desired.
