Ingredients

• 1 pound ground beef
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 cup frozen mixed vegetables (peas, carrots, corn)
• 2 tablespoons tomato paste
• 1 cup beef broth
• 1 teaspoon Worcestershire sauce
• Salt and pepper to taste
• 3 cups mashed potatoes (prepared from about 3 large potatoes)
• 2 tablespoons butter
• 1/4 cup shredded cheddar cheese (optional)

Preparation Method

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking.

Step 2: Cook the Ground Beef

In a large skillet over medium heat, cook the ground beef along with the chopped onion and minced garlic. Stir occasionally until the beef is fully browned and no pink remains. Drain any excess fat from the skillet.

Step 3: Add Vegetables and Seasoning

Add the frozen mixed vegetables, tomato paste, beef broth, Worcestershire sauce, salt, and pepper to the skillet. Stir well to combine and allow the mixture to simmer for 5–7 minutes. This will thicken the sauce slightly and blend the flavors.

Step 4: Layer the Casserole

Transfer the beef and vegetable mixture into the prepared baking dish, spreading it evenly across the bottom.

Step 5: Add Mashed Potatoes

Spread the prepared mashed potatoes evenly over the beef mixture. Dot the top with butter for extra richness.

Optional: Sprinkle shredded cheddar cheese on top for a golden, cheesy crust.

Step 6: Bake

Bake the casserole uncovered in the preheated oven for 20–25 minutes, or until the top is golden and bubbly.

Step 7: Serve

Remove the casserole from the oven and allow it to cool slightly before serving. This Shepherd’s Pie Casserole is best enjoyed warm and makes a hearty, comforting meal for any occasion.

Tips for the Best Shepherd’s Pie Casserole

Use Fresh Mashed Potatoes

Add Herbs and Seasonings

Fresh or dried herbs like thyme, rosemary, or parsley enhance the savory flavors of the beef and vegetables.
