Australian Potato Bake Recipe: Crispy Celery Crown Over Creamy Mustard Cheese Bliss

I've perfected this dish over years of testing, ensuring every bite combines hearty satisfaction with restaurant-quality results at home.

Each layer works together to create a dish that's both comforting and impressive, perfect for family dinners or special occasions.

Ready in about 1 hour with minimal effort, this potato bake is foolproof yet elevated. The aroma alone will have everyone gathering at the table, and the first bite delivers that perfect balance of crispy, creamy, and savory. Let's get baking!

Ingredients for australian potato bake

Nine essential ingredients for that perfect crispy-cheesy Australian potato bake experience.

The potatoes are the foundation—Russets work best for their fluffy texture. Grab the organic variety from Whole Foods if you can, but any russet will do. Thinly slice them (about 1/8-inch thick) and soak in cold water for 10 minutes to remove excess starch. The sharp cheddar is non-negotiable—Cabot or Tillamook brands melt beautifully. For the mustard cheese, pre-shredded works fine, but homemade is easier on your wallet and tastes fresher. The celery crown needs fresh celery—the crunchier, the better. I always grab a bunch from the grocery store's produce section and slice it myself.

No heavy cream? Full-fat coconut milk works in a pinch, though it'll be slightly lighter. Short on mustard cheese? Mix sharp cheddar with 1 tbsp Dijon mustard for that tangy kick. The celery crown can be made with any thinly sliced veggie—carrots or zucchini work too. For extra flavor, add 1/2 tsp garlic powder to the celery mix. The smoked paprika is optional but adds that extra depth that makes this dish feel special. If you're feeling adventurous, swap the chives for fresh parsley or dill—just adjust the amount to taste.

This dish reheats beautifully—200°F for 15 minutes is perfect. Store leftovers in the fridge for up to 4 days, covered tightly. For the celery crown, make it ahead and refrigerate on a wire rack to keep it crisp. The potatoes stay best when baked fresh, but you can assemble the dish ahead and bake straight from the fridge—just add 10 minutes to the cooking time. Freezing isn't recommended, as the texture changes, but you can freeze the celery crown separately for up to 1 month.

Step-by-step instructions for Australian potato bake

Here's how to create that perfect golden crust and velvety filling—every bite delivers crispy celery crown magic over rich, tangy cheese.

Peel the 3 lb Russet Potatoes and slice them ¼-inch thick using a mandoline for even slices. I like to soak them in cold water for 10 minutes to remove excess starch—this prevents gummy texture later. Drain well and pat completely dry with paper towels. The drier the potatoes, the crispier your final bake.

In a large bowl, toss the sliced potatoes with 1 tbsp Dijon Mustard, 1.5 tsp Salt, and 0.5 tsp Black Pepper. The mustard adds that signature tangy depth right from the start. Spread them in an even layer on a baking sheet and let them sit uncovered for 15 minutes—this helps them crisp up beautifully when baked.

Preheat your oven to 375°F. In a medium bowl, combine the 2 cups Sharp Cheddar Cheese, 1 cup Mustard Cheese, 0.5 cup Heavy Cream, 2 cloves Garlic Cloves (minced), and 0.5 tsp Smoked Paprika (if using). Mix until the cheeses are fully melted and the mixture is smooth—this should take about 2 minutes of stirring. The paprika adds subtle smokiness that pairs perfectly with the mustard flavor.

In a separate small bowl, whisk together the 4 tbsp Unsalted Butter and 2 tbsp All-Purpose Flour until you have a smooth paste. This butter-flour mixture will create that irresistible crispy crown on top. Fold this into your cheese mixture until fully incorporated. The texture should be thick but spreadable—like a rich, creamy paste.

Grease a 9x13-inch baking dish generously with butter. Start by creating a base layer with half of your prepped potato slices, pressing them gently into the bottom of the dish. Spread half of the cheese mixture evenly over the potatoes, then add another layer of potato slices. Top with the remaining cheese mixture, spreading it out to cover completely.

Here's the secret: sprinkle the 1 cup Celery Stems (thinly sliced) evenly over the top cheese layer. The celery will soak up the creamy goodness while adding that signature Australian crunch. Press down lightly to help them adhere. Finally, spread the butter-flour mixture evenly over the entire top—this will create that magical crispy crust we're after.

Transfer the baking dish to the preheated oven and bake for 45 minutes. After 30 minutes, the top should start to turn golden brown and the edges should be bubbling. If it's browning too quickly, tent loosely with foil to prevent burning. The celery crown should be crisping beautifully while the cheese underneath melts into a luscious, creamy blanket.

For the final 10-15 minutes, increase the oven temperature to 400°F to get that perfect golden-brown crust. You'll know it's done when the top is deeply golden and the celery crown is crispy enough to stand up on its own. The center should be hot but not bubbling violently—this indicates the cheese is perfectly melted.

Remove the bake from the oven and let it rest for 10 minutes before serving. This resting time allows the layers to set slightly and makes slicing much easier. The contrast between the crispy celery crown and creamy cheese filling will have you reaching for seconds!

Garnish generously with 2 tbsp chopped Chives just before serving. The bright green color and fresh flavor cut through the richness perfectly. Serve warm with a simple green salad or crusty bread to soak up every last bit of that delicious cheese sauce.

Wine and beer pairings for these flavors

Australian Wine Pairings

Australian Shiraz is the perfect match for this rich potato bake—its bold berry notes and subtle spice complement the mustard cheese and smoky paprika.

I reach for a Penfolds Bin 28 or Henschke Hill of Grace from Barossa Valley, where the deep fruit and velvety texture stand up to the dish's creaminess. The wine's natural acidity also cuts through the richness, cleansing your palate between bites. 🍷

Crisp White Options

For a lighter pairing, try an Australian Semillon from the Hunter Valley, like Tyrell's Vat 47. The citrus and honeyed flavors contrast beautifully with the creamy cheese while the crisp acidity balances the dish's richness.

I also love a Sauvignon Blanc from Margaret River—its zesty lime and herbal notes pair wonderfully with the celery crown's freshness.

Beer Pairings

A pale ale with malty sweetness works surprisingly well—I recommend Little Creatures Original from Australia. The caramel and biscuit notes complement the buttery celery crown, while the hoppy bitterness balances the dish's richness. For something lighter, a wheat beer like Tooheys New provides refreshing acidity that cuts through the cheese.

Unexpected Champion

Don't overlook Australian sparkling wine—a Crisp Region sparkling Shiraz adds effervescence that cleanses the palate beautifully. The berry flavors echo the wine's profile while the bubbles keep the meal feeling light. I keep a bottle of House of Arras on hand specifically for rich, cheesy dishes like this one.

Regional Tips

If you're in Australia, ask your local wine shop for a McLaren Vale Grenache—its jammy fruit and earthy notes create a stunning contrast with the dish's creaminess. For those outside Australia, look for South African Shiraz as a close substitute; it shares similar bold fruit characteristics.

Always serve wine slightly chilled (around 55°F) to enhance its refreshing qualities. ✨
