I've made these for every graduation open house this month and every single slow cooker came home completely empty.

These 5-ingredient slow cooker loaded potato rounds are exactly what I’ve been making for every graduation open house this month, and I’m not kidding when I say every single slow cooker has come home completely empty. They’re thick-cut russet potato slices layered in the slow cooker and finished under the broiler so the tops get crispy with little pools of melted cheese. It’s the kind of cozy, game-day-style comfort food that works beautifully on a buffet table because the slow cooker keeps everything warm while guests help themselves. This is a very Midwestern, potluck-friendly recipe—simple ingredients, big payoff, and easy to keep going for hours while people come and go.

Serve these loaded potato rounds straight from the slow cooker on warm, with a big spoon for scooping and a bowl of tongs nearby. I like to set them out on a graduation or game-day spread with a simple green salad, a veggie tray with ranch, pulled pork or shredded chicken sandwiches, and a big bowl of fruit salad. Put out extra toppings—sour cream, sliced green onions, jalapeños, and even a little hot sauce—so everyone can dress theirs up how they like. They pair nicely with iced tea, lemonade, or a cooler of sodas, and they’re just as at home next to burgers and brats on the grill as they are on a party buffet.

Servings: 10-12

3 pounds russet potatoes, scrubbed and sliced into 1/2-inch thick rounds (leave skins on)

1 teaspoon kosher salt, plus more to taste

Prep the potatoes: Scrub the russet potatoes well and pat dry. Leave the skins on for texture and to help the slices hold together. Slice into thick 1/2-inch rounds so they don’t fall apart in the slow cooker. Try to keep the slices as even as you can so they cook at the same rate.

Cook the bacon: In a skillet over medium heat, cook the thick-cut bacon until crisp. Transfer bacon to a paper towel–lined plate to drain, then crumble or chop into small pieces. Carefully reserve about 1 tablespoon of the bacon drippings for extra flavor.

Prepare the slow cooker: Spray the slow cooker insert generously with nonstick cooking spray to help prevent sticking. Drizzle the reserved bacon drippings around the bottom of the insert for added flavor and to encourage those crispy edges on the bottom layer of potatoes.

Season the potatoes: In a large bowl, toss the potato rounds with the kosher salt and black pepper so the seasoning is evenly distributed. You can add a pinch more salt if your bacon and cheese aren’t very salty, but remember you can always adjust at the end.

Layer the first round: Place a single, slightly overlapping layer of potato rounds in the bottom of the slow cooker. Sprinkle a generous handful of shredded cheddar cheese over the potatoes, followed by a spoonful or two of crumbled bacon. Add a few small dollops of sour cream (use about 1/4 cup per layer), spacing them around so they’ll melt down between the slices.

Repeat the layers: Continue layering potatoes, cheese, bacon, and small dollops of sour cream until you’ve used all the potatoes. Finish with a final layer of cheese and a light sprinkle of bacon on top. This top layer is what will turn into those crispy, cheesy bites everyone digs for.

Slow cook: Cover the slow cooker with the lid. Cook on HIGH for 3 to 3 1/2 hours or on LOW for 5 to 6 hours, until the potatoes are very tender when pierced with a fork. Avoid lifting the lid too often so the heat stays consistent and the cheese melts nicely between the layers.

Crisp the top (optional but recommended): For that loaded potato “bites” look with crispy, browned cheese on top, carefully lift the slow cooker insert out of the base (if your model allows) and place it on a baking sheet. Set under a preheated broiler for 3 to 6 minutes, watching closely, until the top cheese layer is bubbly and browned in spots with little pools of melted cheese. Rotate once if needed for even browning. If your insert isn’t oven-safe, you can scoop the top layer into an oven-safe dish and broil just that portion for serving.

Keep warm for serving: Return the insert to the slow cooker base and switch to the WARM setting. Sprinkle with sliced green onions or chives for color and a fresh bite. Keep the lid slightly ajar for the first 10 to 15 minutes if the top is very steamy so the crispy bits don’t soften too quickly. After that, you can cover fully to hold for your open house.

Serve buffet-style: Set the slow cooker on your serving table with a wooden spoon or tongs. Offer extra sour cream, more green onions, and any other toppings on the side. Give the potatoes a gentle scoop from the edges every so often so everyone gets some of the cheesy, crispy top and the creamy middle layers.

Make-ahead tip: You can slice the potatoes and cook/crumbled the bacon up to 1 day ahead. Store potatoes submerged in cold water in the fridge to keep them from browning, and pat them very dry before layering so they don’t steam too much. Assemble in the slow cooker insert just before cooking. For very busy party days, you can fully cook the dish earlier in the day, then rewarm on LOW and finish with the broiler step right before guests arrive. Cheese options: Use a cheddar-jack blend, pepper jack for a little kick, or a mix of sharp cheddar and mozzarella for extra stretch. Pre-shredded cheese is fine for this; it saves time and still melts nicely in the slow cooker. Bacon swaps: If you’d rather not cook bacon at the last minute, you can use real bacon bits from the store—look for the ones in the salad dressing section that are actual bacon, not imitation. Turkey bacon works too; just know it won’t render as much flavorful fat, so you might skip using the drippings and add a light drizzle of olive oil to the bottom of the slow cooker instead. Picky eater ideas: Keep the green onions on the side so kids (or adults) who don’t like “green stuff” can skip them. You can also leave a corner of the slow cooker with less bacon or cheese if you know someone prefers things plain—just mark that section with a little toothpick flag. Ranch dressing drizzled over the top is a fun twist that many kids love. Lighter version: Use light sour cream and reduced-fat cheese if you’d like to cut back a bit. The potatoes will still be comforting and creamy, though the top may not brown quite as deeply. You can also reduce the bacon to 4–6 ounces and add a few extra green onions for flavor. Spicier version: Add a pinch of cayenne or smoked paprika to the salt and pepper when seasoning the potatoes. Serve with sliced jalapeños, hot sauce, or a spicy ranch on the side for guests who like some heat. Food safety tips: Keep the potatoes at a safe temperature during your open house. Once cooked, hold them in the slow cooker on the WARM setting (usually around 165°F or higher) and try not to leave them out unplugged for more than 2 hours. If the party runs long, give the mixture a gentle stir every 30 minutes so the heat distributes evenly. Always use clean utensils for serving, and don’t return any leftovers that have been sitting at room temperature for more than 2 hours back into the fridge. If you’re transporting the slow cooker to another location, keep the lid on tightly, wrap the insert in a towel, and plug it in as soon as you arrive to keep everything at a safe, hot temperature.
