Step 1: Prepare the Potatoes
Dice the potatoes into uniform ½-inch cubes for even cooking. Place the diced potatoes in a large bowl and toss them with 1 tablespoon of olive oil, paprika, garlic powder, salt, and black pepper.

Step 2: Cook the Potatoes
Heat a large, oven-safe skillet (preferably cast iron) over medium-high heat. Add the seasoned potatoes and spread them out into an even layer. Cook for 10-12 minutes, flipping occasionally, until the potatoes are golden and crispy on the outside and tender on the inside. Remove the potatoes from the skillet and set them aside.

Step 3: Cook the Sausage or Bacon
In the same skillet, add the breakfast sausage (or diced bacon) and cook over medium heat, breaking it into small pieces with a spatula. Cook until browned and fully cooked through, about 5-7 minutes. If using bacon, cook until crisp. Remove the cooked sausage or bacon from the skillet and set aside, leaving a small amount of fat in the pan for the vegetables.

Step 4: Sauté the Vegetables
Add the remaining 1 tablespoon of olive oil to the skillet if needed. Toss in the chopped onion and bell pepper, cooking for 3-4 minutes until they begin to soften. Add the sliced mushrooms and cook for an additional 4-5 minutes until they release their moisture and turn golden. If using spinach, stir it in during the last minute of cooking, allowing it to wilt.

Step 5: Combine Everything
Return the cooked potatoes and sausage (or bacon) to the skillet with the sautéed vegetables. Stir everything together to combine, creating an even layer in the skillet.

Step 6: Add the Eggs
Using the back of a spoon, make four small wells in the hash mixture. Crack one egg into each well. Cover the skillet with a lid and reduce the heat to low. Cook for 5-7 minutes, or until the egg whites are set but the yolks remain runny. For fully cooked eggs, cook for an additional 2-3 minutes.

Step 7: Optional Toppings
If desired, sprinkle shredded cheddar cheese over the hash during the last minute of cooking. Garnish the finished hash with fresh parsley for a pop of color and flavor.

Step 8: Serve
Serve the Loaded Breakfast Hash straight from the skillet for a rustic presentation. Pair it with toast, avocado slices, or a dollop of hot sauce for an extra kick.
