Ingredients Overview: What You’ll Need

Before diving into the cooking process, let’s get familiar with the ingredients that will make this dish come to life.

• 1 Pound Ground Beef: The base of the meatballs, this rich and flavorful meat adds that comforting, savory taste. Opt for lean ground beef for a slightly healthier version, or go with a fattier cut for a juicier result.
• 1/2 Cup Breadcrumbs: These act as a binding agent, helping the meatballs hold their shape. They also add a subtle, crispy texture that contrasts nicely with the other elements of the casserole.
• 1/4 Cup Grated Parmesan Cheese: This adds a cheesy depth to the meatballs that’s both savory and slightly nutty, giving them an extra burst of flavor.
• 1 Egg: A key ingredient for binding the meatball mixture together. It ensures that your meatballs stay juicy and hold up well during baking.
• 1 Teaspoon Garlic Powder: Garlic powder is a must for that warm, aromatic base flavor that every good casserole needs. It’s a subtle yet important part of the seasoning.
• 1 Teaspoon Onion Powder: Just like garlic powder, onion powder helps to build layers of savory flavor without being overpowering.
• Salt and Pepper: Always a necessity to balance out the flavors and bring everything together. Adjust according to your personal taste.
• 1 Can of Corn (drained): This adds a touch of sweetness and a bit of texture contrast. The corn pairs beautifully with the other vegetables.
• 1 Can of Peas (drained): A classic veggie pairing for Shepherd’s Pie, peas add vibrant color and a slight earthiness to the dish.
• 1 Can of Diced Tomatoes: These juicy tomatoes offer a slight acidity that cuts through the richness of the meatballs and mashed potatoes, balancing the flavors perfectly.
• Mashed Potatoes: The crowning glory of Shepherd’s Pie. The creamy mashed potatoes serve as the perfect topping, adding comfort and richness.

Step-by-Step Cooking Instructions: Let’s Bring This Dish to Life

Step 1: Preheat Your Oven to 375°F

Start by preheating your oven to 375°F (190°C). This ensures that the casserole cooks evenly and the mashed potatoes get perfectly golden and crisp at the top.

Step 2: Prepare the Meatball Mixture

In a large mixing bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, egg, garlic powder, onion powder, salt, and pepper. Using your hands or a spoon, mix everything together until fully combined. This step is key to getting meatballs that are perfectly seasoned and hold together well. Be careful not to overmix, as that can lead to tough meatballs.

Step 3: Shape the Meatballs

Roll the meatball mixture into 1- to 1.5-inch meatballs and place them into a greased or lightly oiled baking dish. The meatballs should be spaced evenly for even cooking. Don’t worry about them being perfectly round—this is comfort food, not a beauty pageant!

Step 4: Add the Vegetables

Next, layer the corn, peas, and diced tomatoes over the meatballs. The vegetables will infuse the meatballs with extra flavor and moisture as they cook. The juices from the tomatoes will also help create a beautiful sauce-like base for the casserole.

Step 5: Top with Mashed Potatoes

Now comes the best part: the mashed potatoes. Spread them evenly over the meatball and vegetable layer. Be sure to cover the whole surface, sealing the ingredients underneath. For an extra touch, you can use a spoon to create little peaks and valleys in the mashed potatoes, which will get golden and crispy when baked.

Step 6: Bake

Cover the casserole with aluminum foil and bake it in the preheated oven for 45 minutes. After 45 minutes, remove the foil and continue baking for an additional 15 minutes, or until the mashed potatoes are golden brown and slightly crisped at the edges.

Helpful Tips for a Seamless Cooking Experience

1. Use Fresh Mashed Potatoes: If you’re using leftover mashed potatoes, make sure they’re thick and not too runny. Adding a little extra butter or cheese can help with the consistency.

2. Experiment with Veggies: Feel free to add other vegetables like carrots or green beans to customize your casserole. Just be sure to drain them well to avoid excess moisture.

3. Don’t Skip the Foil: The foil helps the casserole retain moisture while baking, keeping the meatballs tender. Just remember to remove it at the end for that perfect crispy potato top.

4. Make Ahead: This recipe is ideal for meal prep. You can prepare the entire casserole and refrigerate it before baking. Just bake it for an extra 10 minutes if it’s cold from the fridge.

5. Cheese Lovers Rejoice: For a cheesy twist, sprinkle some shredded cheese on top of the mashed potatoes during the last 10 minutes of baking.

Storage and Reheating Tips

• Storage: If you have leftovers, store them in an airtight container in the refrigerator for up to 3-4 days. This casserole is even better the next day as the flavors have more time to meld.
• Freezing: This dish freezes well! If you want to store it longer, freeze it before baking. When ready to cook, simply thaw in the fridge overnight and bake as instructed.
• Reheating: Reheat individual portions in the microwave, or warm up the whole casserole in the oven at 350°F for about 20-25 minutes until heated through. You can cover it with foil to retain moisture.
