Step‑by‑Step Instructions for High-Protein Hobo Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it heats, take a 9×13-inch baking dish and grease it generously with olive oil to prevent sticking. This step ensures your High-Protein Hobo Casserole will come out easily after baking and helps create a nice crust on the edges.
Step 2: Brown the Ground Beef
In a large skillet over medium-high heat, add the lean ground beef. Use a wooden spoon to break it apart while it cooks for about 7-10 minutes until browned and fully cooked. Stir occasionally and drain any excess fat to keep your casserole lighter, setting the beef aside once done.
Step 3: Season the Beef
Once the beef is cooked, return it to the heat and season with onion powder, garlic powder, salt, and black pepper. Stir the mixture well for about 2 minutes, allowing the spices to infuse into the meat. This step elevates the flavor profile of your High-Protein Hobo Casserole, ensuring each bite is delicious.
Step 4: Layer the Ingredients
With the seasoned beef ready, it’s time to assemble! Start by layering half of the sliced yellow potatoes evenly in the greased baking dish. Next, add half of the cooked ground beef on top, then sprinkle half of the diced tomatoes over the meat. This creates a flavorful base that will be savory and hearty.
Step 5: Repeat the Layers
Continuing with the layering process, add the remaining sliced potatoes over the first layer, followed by the rest of the ground beef, and top it with the remaining diced tomatoes. This ensures every forkful of your High-Protein Hobo Casserole is filled with all the tasty ingredients and textures that complement each other beautifully.
Step 6: Add the Cheese Topping
Now, generously sprinkle the shredded mozzarella cheese over the final layer of ingredients, ensuring that every corner of the casserole is covered. The cheese will melt and create that gooey, comforting topping that makes this dish so delightful.
Step 7: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes to allow the flavors to meld together. After that, carefully remove the foil and bake for an additional 5 minutes, or until the cheese is golden and bubbly, while the potatoes become tender and cooked through.
Step 8: Let it Rest
Once out of the oven, let the casserole sit for about 5 minutes before serving. This resting period allows the layers to settle and makes it easier to serve. Feel free to garnish with fresh parsley for a pop of color and added freshness right before you dig into your High-Protein Hobo Casserole!
