Step‑by‑Step Instructions for Mashed Potato Spider Web Casserole

Step 1: Prep Potatoes
Begin by peeling and chopping 2 pounds of Idaho® potatoes into even chunks. In a large pot, cover them with salted water and bring to a rapid boil over medium-high heat. Cook the potatoes for 20-25 minutes, or until they are fork-tender. Once soft, drain the water thoroughly and return the potatoes to the pot to keep them warm.

Step 2: Cook Bacon
While the potatoes are boiling, heat a skillet over medium heat and add 8 slices of bacon. Cook the bacon until it is crispy, which should take about 8-10 minutes. Once cooked, transfer the bacon to a paper towel-lined plate to drain excess grease, then crumble it into bite-sized pieces for the casserole.

Step 3: Mash Potatoes
With the drained potatoes in the pot, use a potato masher to mash them over low heat. Gradually mix in 4 tablespoons of butter and 3/4 to 1 cup of milk, stirring until the mixture is smooth and creamy. Make sure there are no lumps for the best texture in your Mashed Potato Spider Web Casserole.

Step 4: Mix Ins
Once the potatoes are creamy, season them with additional salt and black pepper to taste. Spread the mashed potatoes evenly into a greased baking dish. Then, sprinkle the top generously with shredded cheddar or Colby Jack cheese, followed by the crumbled bacon, creating layers of flavor that will delight your guests.

Step 5: Bake
Preheat your oven to 350°F (175°C). Cover the baking dish with foil and bake for 20-30 minutes, or until the cheese is melted and bubbly. Once done, remove the foil and let it cool for a few minutes before moving on to the next step. This will ensure easy application of the sour cream web design.

Step 6: Create Web Design
After the casserole has cooled slightly, take a ziplock bag filled with sour cream and carefully cut a small tip off one corner. Gently squeeze the bag to draw a spider web pattern on top of the mashed potato mixture. This fun design is sure to impress at your Halloween gathering, making the Mashed Potato Spider Web Casserole a centerpiece.

Step 7: Serve
For an extra touch of whimsy, consider adding optional edible spider decorations atop the sour cream web. Serve the casserole warm alongside grilled proteins or as part of a festive buffet, ensuring that your delightful Mashed Potato Spider Web Casserole steals the show!

What type of potatoes should I use?
Absolutely use Idaho® potatoes for the best creaminess! They mash beautifully, but Yukon Gold is also a fantastic substitute if you prefer a richer, buttery flavor.
