Ingredients

• 1 pound Ground beef
• 1 medium Yellow onion, diced
• 2 cloves Garlic, minced
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Smoked paprika (optional)
• 1.5 cups Frozen mixed vegetables (peas, carrots, corn, green beans)
• 1 box Boxed au gratin potato mix
• 2 cups Milk
• 2 cups Boiling water
• 1 cup Shredded cheddar cheese
• 1 tablespoon Olive oil or vegetable oil
• 2 tablespoons Parsley, chopped (for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook for 3-4 minutes, until softened.

Step 3

Add the minced garlic to the skillet and cook for 30 seconds until fragrant.

Step 4

Add the ground beef to the skillet, breaking it apart with a spoon. Season with salt, black pepper, and smoked paprika (if using). Cook until the beef is browned and fully cooked. Drain any excess fat from the skillet.

Step 5

Mix the frozen mixed vegetables into the cooked ground beef, stirring to combine. Remove from heat and set aside.

Step 6

In a large bowl, combine the au gratin potato mix, the cheese sauce packet (from the box), boiling water, and milk. Mix until the sauce components are dissolved.

Step 7

Pour half of the potato and sauce mixture into the bottom of the prepared baking dish, spreading it out evenly.

Step 8

Spread the ground beef and vegetable mixture over the potato layer evenly.

Step 9

Top with the remaining potato and sauce mixture, spreading it to completely cover the beef and vegetable layer.

Step 10

Sprinkle the shredded cheddar cheese evenly over the top layer.

Step 11

Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 25 minutes.

Step 12

Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the top is bubbly and golden brown.

Step 13

Let the casserole rest for 5-10 minutes before serving. Garnish with chopped parsley and serve warm.
