Ingredients for domino potatoes
Six simple ingredients transform into restaurant-worthy domino potatoes with crispy cornmeal crusts.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 ½ lb | Thinly sliced, 1/8-inch thick |
| Cornmeal 🌽 | 1 cup | Fine-ground for even coating |
| Sharp White Cheddar Cheese 🧀 | 1 cup | Shredded, block preferred |
| Mozzarella Cheese 🧀 | 1 cup | Shredded, part-skim works |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Garlic Powder 🧄 | 1 tbsp | Freshly ground preferred |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked for flavor |
| Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Green Onions 🧅 | 4 whole | Thinly sliced, for garnish |
| Paprika 🌶️ | 1 tsp | Smoked for extra flavor |
| All-Purpose Flour 🌾 | 2 tbsp | For dusting potato slices |
The potatoes are the foundation—Russet potatoes are ideal for their high starch content, which creates that perfect fluffy interior. Look for firm, unblemished potatoes at the grocery store, preferably organic if you're picky about skin quality. A mandoline slicer makes even cuts effortless, but a sharp knife works too if you take your time. The key is 1/8-inch slices—thinner slices crisp faster, but thicker ones hold together better. Store potatoes in a cool, dark place until ready to use, but don't peel them until just before slicing to prevent oxidation. For the cornmeal, Bob's Red Mill or Annie's are reliable brands that give a fine, even coating without clumping.
No sharp cheddar on hand? Pepper Jack or Gruyère work beautifully, though the flavor profile will shift slightly. The mozzarella can be low-moisture shredded for convenience, but freshly shredded from a block melts more smoothly. Butter lovers, don't compromise—full-fat is non-negotiable here for that rich, velvety texture. If you're watching calories, light cream works but loses some of that luxurious mouthfeel. The garlic powder can be swapped for fresh minced garlic at double the amount, but pre-ground is fine for everyday cooking. For the cornmeal coating, mix it with a pinch of salt beforehand to ensure even seasoning throughout each layer.
Prepped potatoes can sit in the fridge for up to 2 hours before baking, but work best immediately for maximum crispiness. Once baked, these keep well for 3-4 days in an airtight container—reheat in a 350°F oven for 10-15 minutes until edges are crispy again. The cheese filling can be prepped ahead and stored separately for up to 2 days, but the cornmeal crust loses its crunch if baked later. For meal prep, portion into individual servings before baking so you can reheat just what you need. Freezing isn't recommended—the texture suffers when thawed. These reheat beautifully, though, so double the batch if you're feeding a crowd.

Step-by-step instructions for crispy cornmeal domino potatoes
Mastering these golden, crispy potatoes is all about technique—even slicing and layering matter.
Prep and Season the Potatoes
Slice the 2.5 lb russet potatoes into 1/8-inch thick pieces using a mandoline or sharp knife. I find the mandoline gives the most even slices—critical for consistent cooking. As you slice, place them in a large bowl of cold water to prevent browning.
Drain and thoroughly pat the potato slices dry with paper towels. Moisture is the enemy of crispy results. In a separate bowl, whisk together 1 cup cornmeal, 1 tbsp garlic powder, 1.5 tsp kosher salt, 1 tsp paprika, and 1 tsp ground black pepper. Toss the potatoes in this seasoned cornmeal mixture until every slice is evenly coated. This step ensures maximum crispiness and flavor penetration.
Layer and Bake the Potatoes
Preheat your oven to 425°F with the rack positioned in the middle. In a 9x13-inch baking dish, create the first layer by arranging half the potato slices in a slightly overlapping pattern. This creates the classic "domino" effect that gives the dish its name. Sprinkle half of the 1 cup sharp white cheddar cheese and 1 cup mozzarella cheese evenly over the potatoes.
Repeat with the remaining potato slices and cheeses, finishing with another layer of cheeses on top. Drizzle the 0.5 cup melted unsalted butter evenly over the top, then pour the 0.5 cup heavy cream over the butter. The cream will bubble up during baking, creating a rich, golden crust. Bake uncovered for 45 minutes until the edges are deep golden brown and the cheese has melted into a bubbly blanket.
Broil for Maximum Crispiness
Switch your oven to broil and place the baking dish on the top rack. Broil for 3-5 minutes until the top is deeply golden brown and the cheese has developed a crispy crust. Watch carefully—this step happens quickly, and you want the top to be golden, not burned. The potatoes should be tender enough to pierce easily with a fork, with no resistance from the potato itself.
Remove from the oven and let rest for 5 minutes before slicing. This resting period allows the layers to set slightly, making it easier to create clean, even slices. Use a serrated knife to cut through the layers, preserving that beautiful domino pattern. Garnish immediately with thinly sliced 4 whole green onions for freshness and color.
Serve Warm for Best Texture
Serve the domino potatoes immediately while still warm. The contrast between the crispy top layer, creamy cheese center, and tender potatoes creates the perfect bite. For extra flavor, drizzle with additional melted butter or serve alongside a simple green salad. The potatoes should hold their shape when sliced, with a satisfying crunch on the outside and creamy, cheesy goodness within.
This dish makes 6 generous servings—perfect for family dinners or holiday gatherings. The key to success lies in precise slicing, thorough drying, and that final broil step. Don't skip the resting time; it ensures clean slices and maintains the texture you worked so hard to achieve.
Pro Tips For Making Domino Potatoes
- Parboil First: Drop those Russets in boiling water for 5 minutes before baking—yes, even if the recipe skips it. I learned this the hard way when my potatoes turned to glue inside. This step keeps them from falling apart when you slice them later, and the texture stays firm and fluffy.
- Shred Cheese Hot: Microwave the cheddar and mozzarella for 20 seconds before shredding—it melts faster and sticks better. Cold cheese clumps like a nightmare, and you’ll end up with dry, uneven coverage. (Trust me, I’ve seen it happen.)
- Don’t Overcrowd the Pan: Leave at least 1 inch between potato slices when baking, or they’ll steam instead of crisp. I used to jam them in tight, and they’d turn soggy in the middle. Spread them out like a proper domino stack—neat, even, and crispy.
- Butter the Cornmeal: Mix the cornmeal with melted butter before coating the potatoes—it creates a crispier, richer crust. Dry cornmeal just won’t stick, and you’ll end up with sad, bland edges. A little extra effort here makes all the difference.
Storing and reheating your domino potatoes
Refrigerator Storage
Store your domino potatoes in an airtight container for up to 3-4 days in the fridge. The cornmeal crust stays crispier longer when kept in a single layer rather than stacked.
I use glass Pyrex containers because they maintain even temperatures and prevent moisture buildup. Let the potatoes cool completely before sealing to avoid condensation, which can make the crust soggy. 🥔
Freezer Prep Tips
While these potatoes aren't ideal for freezing (texture suffers), you can prep the cheese filling separately for up to 2 days in the fridge. For meal prep, assemble the dish in the baking dish and refrigerate uncovered for 1 hour before baking—this helps the cornmeal crust crisp better when reheated.
If you must freeze, bake first, then freeze cooled slices in single layers on a tray before transferring to a bag. Thaw overnight in the fridge before reheating. ❄️
Oven Reheating
For best results, reheat in a 350°F oven for 10-15 minutes until the edges are golden and crispy again. Cover loosely with aluminum foil for the first 5 minutes to revive moisture, then uncover to crisp the top.
I like to add 1 tbsp melted butter before reheating to restore richness. Avoid microwaving—it turns the crust rubbery and the cheese greasy. 🔥
Stovetop Crisp Revival
For a quick fix, heat a nonstick skillet over medium heat and add the potatoes in a single layer. Cover with a lid for 3-4 minutes to warm through, then uncover and cook 1-2 minutes until the bottom crisps.
Finish with a sprinkle of cornmeal and a pat of butter for that authentic texture. This method works best for smaller portions. 💡
Garnish Refresh
After reheating, brighten up the dish with fresh green onions or a pinch of smoked paprika. A drizzle of hot honey adds sweetness, while crumbled bacon brings smoky depth.
For extra crunch, toast panko breadcrumbs in the oven and sprinkle on top before serving. These finishing touches make reheated potatoes taste almost as good as fresh! 🌶️

Frequently asked questions
Why do the potatoes need to be sliced so thinly?
Thin 1/8-inch slices ensure even cooking and maximum crispiness. Thicker slices would take too long to cook through, resulting in a mushy interior while the outside burns. The uniform thickness also helps the cornmeal crust adhere perfectly to each slice for that satisfying crunch.
Can I substitute cornmeal with another flour?
While cornmeal gives the signature texture, you can use all-purpose flour or panko breadcrumbs in a pinch. For best results, mix 1 cup flour with 1 tbsp baking powder to help create lift. However, the flavor and texture won't be identical to the cornmeal's natural crunch.
How do I fix soggy potatoes after baking?
If your potatoes turn out soggy, the issue is likely moisture. For future attempts, ensure slices are completely dry before coating, and don't skip the broiling step—it creates that final crispy seal. If already baked, try reheating in a 400°F oven for 10 minutes uncovered to revive the crust.
What's the best way to make these gluten-free?
Replace the cornmeal with gluten-free cornstarch or certified gluten-free flour blend. For extra crispiness, add 1 tbsp arrowroot powder to the coating. Check all cheeses and broths (if using) for hidden gluten, and use tamari instead of soy sauce if needed. The texture will be slightly different but still delicious!
Can I make domino potatoes ahead of time?
Yes! Assemble the dish in the baking dish, cover, and refrigerate for up to 24 hours before baking. This helps the cornmeal crust crisp better when reheated. For serving later, bake at 425°F for 5-10 minutes longer than usual to compensate for the cold start.
