Step‑by‑Step Instructions for Hamburger and Mashed Potato Casserole
Step 1: Boil Potatoes
Peel and cube the potatoes, then place them in a large pot of salted water. Bring the water to a boil and cook for 15–20 minutes, or until the potatoes are fork-tender. Drain the potatoes thoroughly, then mash them together with milk, butter, and a pinch of salt and pepper until creamy and smooth.
Step 2: Cook Meat
In a large skillet, heat a tablespoon of olive oil over medium heat. Add the finely chopped onion and minced garlic, sautéing for about 3–4 minutes until they soften and become translucent. Next, add the ground beef to the skillet, cooking until completely browned, which should take about 6–8 minutes. Drain any excess fat to keep the Hamburger and Mashed Potato Casserole light.
Step 3: Add Flavor
Once the meat is browned, stir in the tomato paste, dried Italian seasoning, and any desired spices. Pour in the broth, followed by the frozen mixed vegetables, and bring the mixture to a simmer. Allow it to cook for 5–7 minutes until it thickens up slightly, and then season to taste with salt and pepper.
Step 4: Layer Casserole
Preheat your oven to 375°F (190°C). In a greased baking dish, spread half of the creamy mashed potatoes evenly across the bottom. Layer the meat mixture over the potatoes, followed by a generous sprinkle of shredded cheddar cheese. Top with the remaining mashed potatoes, smoothing it evenly, and finish with another layer of cheese for that perfect golden topping.
Step 5: Bake
Place the assembled Hamburger and Mashed Potato Casserole in the preheated oven and bake uncovered for 25–30 minutes. You’ll know it’s ready when the cheese is melted and bubbly, and the top has turned a delightful golden brown. Keep an eye on it to avoid over-browning.
Step 6: Cool & Garnish
After baking, remove the casserole from the oven and let it cool for about 5–10 minutes to allow the layers to set. For a fresh finishing touch, sprinkle chopped parsley or green onions over the top before serving. This adds a lovely pop of color and flavor to your meal!
