Izzy's Potatoes Recipe: Buttery Cornmeal Crowns With Mustard-Infused Tang

This Izzy's Potatoes recipe delivers crispy, golden cornmeal crowns with a tangy mustard kick that transforms simple potatoes into a showstopping side dish. 🌟 The secret lies in the double-coating technique—first with cornmeal for texture, then with a mustard-infused butter that adds depth without overpowering the natural potato flavor.

I developed this after years of experimenting with potato preparations, and it’s now a staple at my dinner table.

The process is straightforward yet precise: you’ll start with evenly cut potatoes that roast until tender before getting that signature crunchy exterior. The mustard-infused butter isn’t just a topping—it’s the game-changer, adding a bright, slightly sharp contrast to the buttery cornmeal crust.

This recipe balances simplicity with professional results, making it perfect for weeknight dinners or holiday feasts.

By the time you serve these potatoes, you’ll have a dish that’s crispy on the outside, tender on the inside, and packed with layers of flavor. The golden-brown crowns hold their shape beautifully, while the mustard-infused butter ties everything together in every bite.

It’s the kind of side that elevates any meal—whether paired with roasted meats or served as a standalone centerpiece.

Ready in about 45 minutes, this recipe requires minimal prep but delivers restaurant-quality results. The best part? It’s versatile enough to pair with grilled chicken, steak, or even a hearty vegetable stew. Let’s get started on creating these buttery, tangy potato crowns that will have everyone asking for seconds.

Ingredients for izzy's potatoes

Potatoes, cornmeal, and mustard-infused butter—this trio creates restaurant-worthy potato crowns every time.

Russet potatoes are non-negotiable here—their starchy interior stays creamy while the skin crisps perfectly. Buy them in bulk at Costco for the best price, or grab a couple of large ones at Whole Foods if you want organic. Avoid waxy potatoes like Yukon Golds—they won’t hold their shape after roasting. The cornmeal should be fine grind (not self-rising) for that signature crunch. I always grab mine from the baking aisle at Trader Joe’s—it’s the perfect texture without any weird additives. For the mustard, Maille or Amora are my go-tos, but any smooth Dijon works. The key is using high-quality ingredients because this dish relies on their natural flavors.

No cornmeal? Panko breadcrumbs work in a pinch, but the texture won’t be quite the same. Running short on butter? Substitute with an equal amount of duck fat—it’s got a richer flavor that pairs beautifully with the mustard. Fresh parsley wilting? Dried parsley at one-third the amount does the trick, though fresh is always better. The heavy cream is optional but adds a luxurious touch if you’re serving this as a centerpiece. For the mustard-infused butter, don’t skip the garlic powder—it’s what ties the whole flavor profile together. If you’re feeling adventurous, swap the smoked paprika for a pinch of cayenne for a subtle kick. The olive oil should be light, not extra-virgin, so it doesn’t overpower the delicate flavors.

These potatoes reheat beautifully—just pop them in a 350°F oven for 10-15 minutes until crispy again. Store leftovers in an airtight container for up to 4 days, though I’ve never had any last that long. For meal prep, double the batch and freeze half—just thaw overnight in the fridge before reheating. The mustard-infused butter can be made a week ahead and stored in the fridge, wrapped tightly in parchment. Trust me, you’ll want to make extra—it’s the perfect condiment for grilled meats or even toasted bread.

Step-by-step instructions for izzy's potatoes recipe

Here's how to transform humble russets into golden, buttery crowns with a mustard-kissed crunch.

In a shallow bowl, whisk together the 0.5 cup cornmeal, 1 tsp garlic powder, 0.5 tsp smoked paprika, 1 tsp diamond crystal kosher salt, and 0.5 tsp black pepper. The cornmeal should be fine and free of lumps—if you see any, give it a quick pulse in a food processor. This coating will create that signature crispy crown around each potato.

In a separate bowl, melt the 0.5 cup unsalted butter until just liquid, then whisk in the 2 tbsp dijon mustard until fully combined. The mustard adds that signature tangy depth that makes these potatoes unforgettable. Let this butter mixture cool slightly—it should be warm but not hot when you use it.

Peel the 2 lb russet potatoes and cut them into 1-inch thick rounds, keeping the slices as even as possible. I use a mandoline for perfect uniformity, but a sharp chef's knife works too—just stay steady. The thickness matters: too thin and they'll overcook; too thick and the centers stay doughy.

Toss the potato slices immediately with 2 tbsp olive oil to prevent browning while you work. Arrange them in a single layer on a baking sheet, leaving ½ inch between each slice. This spacing ensures even browning and crisping later. If you have time, let them sit uncovered for 15 minutes—this helps draw out excess moisture for extra crispiness.

Heat a large oven-safe skillet over medium-high heat. Add the potato slices in a single layer, leaving space between them. Cook undisturbed for 3-4 minutes until the bottoms develop a golden brown crust—this is your sear. Flip carefully with a spatula and repeat on the other side. You're building that foundational crunch right here.

Remove the skillet from heat and quickly transfer the potatoes to a plate. Working fast, toss each slice in the cornmeal mixture first, pressing gently to adhere. Then flip and coat with the mustard butter, letting it soak in slightly. The potatoes should look like they're wearing little golden crowns—this is where the magic happens.

Return the skillet to the stove over medium heat for 1 minute to melt any butter that didn't stick, then transfer the skillet to a 425°F preheated oven. Bake for 15-18 minutes until the edges are deep golden brown and the potatoes are tender when pierced with a fork. The cornmeal should be crisp, not crumbly—this means it's properly toasted.

For extra richness, stir the 0.25 cup heavy cream into the pan juices during the last 2 minutes of baking. The steam will help create a luscious sauce that pools at the bottom of the skillet. Remove from oven and let rest for 3 minutes—this prevents the crowns from falling apart when you serve.

Gently transfer the potatoes to a serving platter, arranging them with the crispy sides up. Spoon any pan juices over the top, then sprinkle with 0.25 cup chopped fresh parsley for a pop of color. The contrast of crispy crowns, creamy centers, and that mustard-infused tang makes these potatoes irresistible.

Serve immediately while the crowns are still crunchy and the centers are warm. These potatoes shine as a side dish but are hearty enough to stand alone—just add a simple green salad and you've got a complete meal. The secret? That perfect balance of crispy, creamy, and tangy in every bite.

Serving suggestions for leftovers

Plating Presentation

Arrange the potatoes on a platter with the crispy cornmeal crowns facing up to showcase their golden texture. I like to create a circular pattern, alternating the slices with the mustard butter drizzled between them for visual appeal.

A light dusting of smoked paprika around the edges adds a subtle pop of color that ties into the dish's flavor profile. 🌟

Garnish Ideas

Fresh chopped parsley adds a vibrant green contrast that brightens the dish, while a sprinkle of flaky sea salt enhances the buttery notes. For a smoky touch, add a few toasted pumpkin seeds—their crunch complements the cornmeal crust beautifully.

If you're feeling adventurous, a drizzle of truffle oil (just ½ teaspoon) elevates the dish to gourmet status.

Pairing with Proteins

These potatoes pair perfectly with grilled steak or pan-seared chicken breast, where the mustard-infused butter cuts through the richness. For a lighter option, serve alongside herb-roasted salmon—the tangy potatoes balance the fish's delicate flavor.

I often make a double batch when hosting, because they disappear fast when paired with hearty mains. 🍗

Vegetable Pairings

A simple arugula salad with lemon vinaigrette cleanses the palate between bites, while roasted asparagus with garlic and olive oil adds a fresh, crisp contrast. For a heartier option, serve with sautéed mushrooms and thyme—their earthy notes complement the potatoes' buttery crunch.
