Ingredients

• 1 pound ground beef
• 1 medium, diced onion
• 2 minced garlic cloves
• 8 ounces tomato sauce
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 4 large, peeled and cubed russet potatoes
• 4 tablespoons unsalted butter
• 0.5 cup milk
• 2 cups shredded cheddar cheese
• 1 cup frozen mixed vegetables
• 2 sliced thinly green onions
• 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

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.

Step 3

Add ground beef to the skillet and cook until browned, breaking it up with a wooden spoon. Sprinkle with salt and black pepper.

Step 4

Stir in tomato sauce and let it simmer for 5 minutes. Set aside.

Step 5

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.

Step 6

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.

Step 7

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.

Step 8

Now it’s time to assemble. Spread the ground beef mixture evenly in the bottom of a 9x13-inch baking dish.

Step 9

Layer the mashed potatoes on top of the beef mixture, smoothing them out with a spatula.

Step 10

Spread the vegetable and cheese mixture over the mashed potatoes as the final layer.

Step 11

Sprinkle the remaining 1 cup of shredded cheddar cheese on top.

Step 12

Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbling and the cheese is melted and golden.

Step 13

Remove from the oven and let it rest for 5 minutes before serving. Garnish with the remaining green onions, if desired.
