#### Step 1: Prepare the Ingredients
Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil to prevent sticking.
Next, peel and slice the potatoes thinly, about 1/8-inch thick. This ensures that they cook evenly in the casserole. You can use a mandoline slicer for uniform slices, which helps with even cooking.
Add the diced onion and garlic to the skillet and sauté for an additional 3-4 minutes, until the onions soften and become fragrant. Season with oregano, paprika, salt, and pepper. Stir to combine. Once the sausage mixture is cooked, remove from heat and set aside.
#### Step 3: Assemble the Casserole
Now it’s time to layer the casserole. Begin by layering the bottom of the greased baking dish with a portion of the sliced potatoes. Next, spoon half of the cooked sausage mixture over the potatoes. Repeat the layers, finishing with a final layer of potatoes on top.
#### Step 4: Add Mozzarella Cheese
Top the casserole with the shredded mozzarella cheese, spreading it evenly over the surface. The cheese will melt and form a golden, bubbly crust as the casserole bakes.
If you want a crispier top, you can broil the casserole for an additional 2-3 minutes at the end of baking.
For an extra touch, you can garnish with freshly chopped herbs like parsley or thyme before serving. The fresh herbs will add a pop of color and flavor to the dish.
### Why This Casserole is So Delicious
### Tips for the Best Baked Potato and Sausage Casserole
– **Slice Potatoes Thinly**: For even cooking, make sure to slice the potatoes thinly. Thick slices may not cook through in the time it takes for the casserole to bake.
– **Use a Starchy Potato**: Russet potatoes work best for casseroles because they hold their shape and have a fluffy texture when baked. You can also use Yukon Gold potatoes for a creamier texture.
– **Add Extra Veggies**: Feel free to include more vegetables for added flavor and nutrients. Sautéed mushrooms, bell peppers, or spinach can be layered into the casserole for extra taste.
– **Make Ahead**: This casserole can be assembled ahead of time and stored in the fridge for up to 24 hours before baking. This makes it a great option for meal prep or when you want to prepare dinner in advance.
