Ingredients for betty crocker potato casserole
Six ingredients make this nostalgic casserole shine—creamy, crispy, and cheesy perfection in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 4 lb | Medium-sized, peeled and sliced thin |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into small cubes |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, sharp flavor preferred |
| Milk 🥛 | 1 cup | Whole milk for richness |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | 1 tsp | For savory depth |
| Onion Powder 🧅 | 1 tsp | Adds subtle sweetness |
| Breadcrumbs 🍞 | 1 ½ cups | Panko for extra crunch |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated for topping |
| Green Onions 🧅 | 3 whole | Sliced thin for garnish |
The potatoes are everything here. Russets are your best bet—they’re starchy and fluffy when cooked right. Grab a 4-pound bag from Kroger or Walmart for the best price, and skip the pre-cut bags (they brown faster). Peeled and sliced thin, they cook evenly and soak up the creamy sauce. For extra crispiness, I always pat them dry with a paper towel before layering—water is the enemy of crunch. If you’re short on time, a mandoline slicer makes quick work of it, but a sharp knife works too.
No heavy cream? Whole milk plus 2 tbsp melted butter gets you close. Cheddar too salty? Mild cheddar plus a pinch of sugar balances it out. Breadcrumbs not panko? Toast regular breadcrumbs in butter first—they’ll still get crispy. The garlic and onion powders are non-negotiable for that classic savory kick, but if you’ve got fresh, 1 tsp each minced will take it to the next level. And for the love of crispy tops, don’t skip the Parmesan—it adds that nutty, umami punch that makes the whole dish sing.
This casserole reheats beautifully—350°F for 15-20 minutes until bubbly. Leftovers keep for 4-5 days in the fridge, but honestly, it’s best the first day. For meal prep, assemble it ahead and refrigerate overnight—the flavors meld even better. Freezes well too: bake as usual, cool completely, then wrap tightly. 3 months in the freezer, and it’s just as good as day one. Garnish with green onions right before serving—they add a fresh pop of color and brightness.

Step-by-step instructions for cheesy crisp-top potato casserole
Here's how to make this classic comfort dish with a perfect golden crust and creamy filling.
👨🍳 Step 1: Prepare the Potato Mixture
Preheat your oven to 375°F. Peel and thinly slice the 4 lb russet potatoes (about ⅛-inch thick) using a mandoline or sharp knife. You should have about 6 cups of sliced potatoes. Boil them in salted water for 8-10 minutes until just tender but still holding their shape. Drain well and return to the pot.
While the potatoes cool slightly, melt the 0.75 cup unsalted butter in a large skillet over medium heat. Add the 2 cups sharp cheddar cheese, stirring until melted and smooth. Remove from heat and stir in the 1 cup heavy cream, 1 cup milk, 0.25 cup all-purpose flour, 1 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, and 1 tsp onion powder until fully combined.
🥘 Step 2: Combine Potatoes and Cheese Sauce
Pour the warm cheese sauce over the drained potatoes and gently toss until every slice is coated. The mixture should look creamy and well-combined. Transfer everything to a large greased 9x13-inch baking dish, spreading it evenly in a single layer. You'll want the potatoes to touch each other closely for that classic casserole texture.
Sprinkle the sliced 3 whole green onions evenly over the top. This adds freshness that cuts through the richness. Cover the dish with aluminum foil and bake for 30 minutes to let the flavors meld and the potatoes soften completely.
🔥 Step 3: Create the Crispy Topping
While the potatoes bake, prepare the topping by mixing the 1.5 cups breadcrumbs and 0.5 cup parmesan cheese in a bowl. The breadcrumbs should be panko for that extra crunch you love in classic casseroles. After the initial 30 minutes of baking, uncover the dish and sprinkle the breadcrumb mixture evenly over the top, pressing down gently with your fingers.
Return to the oven and bake uncovered for another 20-25 minutes until the topping is deep golden brown and the edges are bubbling. The casserole is done when the cheese is melted and the topping is crispy enough to stand up to a gentle tug. Let it rest for 5 minutes before serving—this helps the topping set properly.
🍽️ Step 4: Serve Warm with Fresh Garnish
Cut into squares and serve immediately while the topping is still crispy. The creamy potato filling should be perfectly tender with just a slight bite, while the top should be golden and crunchy. Garnish with extra green onions if desired, though the ones baked in already provide beautiful color contrast.
Here's the thing—this casserole tastes even better the next day, so leftovers reheat beautifully. Just cover with foil and warm in the oven at 350°F for 15-20 minutes until heated through. The crispy topping might soften slightly, but it's still delicious!
Pro Tips For Making Betty Crocker Potato Casserole
- PARBOIL POTATOES FIRST: This isn’t just a suggestion—it’s the difference between mushy and perfect slices. After peeling, drop whole Russets into boiling water for 5 minutes before slicing. They’ll hold their shape better when baking, and you’ll avoid the sad, soggy layers that happen when raw potatoes steam instead of brown.
- USE SHREDDED CHEESE DIRECTLY: Skip the pre-shredded bag—it’s coated with anti-caking agents that turn to gummy sludge when melted. Buy a block of sharp cheddar, grate it yourself (pulse in a food processor for evenness), and mix it straight into the cream sauce. Your casserole will taste like actual cheese, not processed filler.
- BAKE COVERED THEN UNCOVERED: The first 20 minutes with foil on keeps the top from drying out while the potatoes soften. After that, remove the foil and crank the oven to 400°F for the last 10 minutes. This crispy finish is what turns a good casserole into a great one—don’t skip the broil if your oven handles it.
- SWAP CREAM FOR HALF-AND-HALF: Heavy cream makes the sauce rich, but it can turn greasy if overcooked. Mix equal parts heavy cream and whole milk (or half-and-half) for a lighter texture that still coats the potatoes beautifully. The dairy won’t separate, and the final dish stays creamy without feeling heavy.
Essential equipment for this recipe
Must-Have Baking Dish
This casserole demands a 9x13-inch baking dish—it's the perfect size for even heat distribution and that signature golden crust. I swear by CorningWare Stoneware for its durability and even baking, but any light-colored metal or glass dish works.
Avoid dark pans—they absorb heat unevenly and can burn the topping before the center cooks. Pro tip: Grease your dish with butter or nonstick spray before adding the potatoes to prevent sticking. 🔥
Essential Mixing Tools
For the creamy cheese sauce, a medium-sized mixing bowl (at least 3-quart capacity) keeps everything contained while stirring. I use a wooden spoon or heat-resistant silicone spatula to scrape every last bit of melted cheese from the pan.
For the crispy topping, a small bowl (like a Rubbermaid Take-Along) works perfectly for mixing the breadcrumbs and Parmesan. A sharp chef's knife is non-negotiable for slicing potatoes—mandoline slicers save time but require caution. 🧈
Cheese Grater Game-Changer
Freshly grated cheese makes all the difference. Skip the pre-shredded stuff—it contains anti-caking agents that create a gummy texture. Invest in a microplane grater for Parmesan or a box grater for cheddar. I love the OXO Good Grips for its safety and efficiency.
For the breadcrumbs, panko is ideal, but if you're using regular breadcrumbs, toast them in a dry skillet for 2-3 minutes over medium heat to enhance their crunch. 🍞
Temperature Control Tools
An oven thermometer is my secret weapon—most home ovens run hot or cold, and this casserole needs precise heat. I use the Thermoworks Oven Thermometer to ensure my 375°F setting is accurate.
For the crispy topping, a digital instant-read thermometer (like Thermapen) helps verify the internal temp reaches 165°F at the center. A timer (even your phone works) prevents overbaking—the topping should be golden, not burnt. ⏰
Optional Pro Upgrades
Want restaurant-quality results? A laser thermometer (like Meater) lets you check the baking dish's surface temp for even browning. For extra crispiness, I sometimes broil the casserole for 1-2 minutes at the end—watch it like a hawk to avoid burning.
A pastry brush comes in handy for brushing melted butter on the topping before the final bake. And if you're meal prepping, mason jars with vacuum-sealed lids keep leftovers fresh for 5-6 days in the fridge. 💡

Frequently asked questions
Can I make this casserole ahead of time?
Assemble the casserole in your baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. The flavors actually deepen overnight. For best results, bake it straight from the fridge—just add 10-15 extra minutes to the baking time to account for the cold start.
What if I don't have panko breadcrumbs?
No problem! Use regular breadcrumbs, but toast them in a dry skillet over medium heat for 2-3 minutes until golden. This adds extra crunch to your topping. For even better texture, mix in 1 tablespoon melted butter with the breadcrumbs before sprinkling on top.
How do I make this dish lower in fat?
Swap half the butter for Greek yogurt or evaporated skim milk in the cheese sauce. Use low-fat cheddar and reduce the breadcrumbs to 1 cup while adding 1 tablespoon cornstarch to the sauce for thickening. The texture stays creamy but with fewer calories.
Why did my topping turn soggy?
Soggy topping usually means the potatoes released too much moisture. Always pat sliced potatoes completely dry before layering, and consider baking the uncovered portion for 5 extra minutes to evaporate excess steam. Another trick: sprinkle 1 tablespoon cornstarch over the potatoes before adding the cheese sauce.
Can I use sweet potatoes instead?
Yes! Sweet potatoes work beautifully—they add natural sweetness that pairs well with the cheese. Peel and slice them ⅛-inch thick, then boil for 6-8 minutes until tender. Reduce the baking time by 5 minutes since sweet potatoes cook faster than russets.
