1-Step One: Prepare Your Equipment and Potatoes Begin by preheating your oven to 350°F. This moderate temperature allows the casserole to heat through evenly without drying out the edges. Lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking and make cleanup easier. Fill a large pot with water and add a generous tablespoon of salt, bring it to a rolling boil over high heat. While waiting for the water, rinse your potatoes thoroughly under cold water. You can leave the skins on for added nutrition and a rustic texture, or peel them if you prefer smoother mashed potatoes. Cut larger potatoes into quarters or halves to ensure even cooking.

2-Step Two: Cook and Mash the Potatoes Add the potatoes to the boiling water and cook until they’re fork-tender, typically 15 to 20 minutes depending on size. Test by inserting a fork into the largest piece, it should slide in easily with minimal resistance. Drain the potatoes thoroughly in a colander, then return them to the warm pot. Using a potato masher, roughly mash the potatoes directly in the pot. Some small lumps are perfectly fine and add pleasant texture to the finished casserole. Avoid over-mashing, which can make the potatoes gummy. If you prefer ultra-smooth potatoes, a hand mixer on low speed works well, but stop as soon as the potatoes reach your desired consistency.

3-Step Three: Mix in the Loaded Potato Ingredients Add the softened cream cheese and butter to the hot potatoes. The residual heat will help these ingredients blend smoothly without needing additional milk. Stir gently until both are fully incorporated and the potatoes become creamy and rich. Fold in the crumbled bacon, shredded cheese, and sliced green onions. Reserve a small handful of bacon and cheese for garnish if desired. Season with salt and pepper to taste, remembering that the bacon and cheese already contribute significant saltiness. Spread this mixture evenly across the bottom of your prepared baking dish, creating a level foundation for the pork layer.

4-Step Four: Layer the Pulled Pork Distribute the pulled pork evenly over the potato base. Whether you’re using homemade slow cooker BBQ pulled pork or a quality store-bought version, make sure the pork is at room temperature for even heating. If your pulled pork includes BBQ sauce, that’s perfect, the tangy sweetness complements the creamy potatoes beautifully. Press the pork gently into the potatoes to create a cohesive layer that holds together when serving. This technique ensures each spoonful captures both the pork and potato layers together.

5-Step Five: Add Cheese and Bake Sprinkle the remaining 4 ounces of shredded cheese over the pulled pork layer. Cover the baking dish with aluminum foil to trap moisture and prevent the cheese from over-browning during the initial baking phase. Bake covered for 15 minutes at 350°F. Then remove the foil and continue baking for an additional 5 minutes, or until the cheese is completely melted and slightly bubbly. The casserole should be heated through to the center, reaching an internal temperature of 165°F for food safety.

6-Step Six: Garnish and Serve Remove the casserole from the oven and let it rest for 5 minutes before serving. This brief resting period allows the layers to set slightly, making serving easier and preventing the filling from spreading too much on plates. Garnish with the reserved green onion slices for a fresh pop of color and mild onion flavor. Serve hot, scooping generous portions that include all three layers. This casserole pairs wonderfully with a simple green salad or steamed vegetables for a complete meal.
