Ingredients You’ll Need

These ingredients might sound simple, but together they create pure magic in your oven. The key is to use fresh potatoes with a bit of starch to get that creamy texture, and don’t skip on the cheese—it’s the crowning glory of this bake.

• Potatoes: I prefer waxy or all-purpose potatoes for this bake to hold their shape well, but Yukon Golds work beautifully too.
• Cream: Heavy cream is ideal for richness, but you can use a mix of cream and milk if you want to lighten it up.
• French Onion Soup Mix: This is a secret weapon—adds heaps of flavor with minimal effort. If you can find a quality mix, don’t hesitate to use it.
• Tasty Cheese (Grated): Sharp cheddar or a flavorful Aussie tasty cheese melts perfectly and adds a lovely savory finish.

Variations

I love keeping this recipe simple, but you can totally make it your own. I’ve tried a few twists over time, and each one brings a little extra flair without complicating the process.

• Add Fresh Herbs: I sometimes sprinkle chopped rosemary or thyme between layers for a fragrant punch that pairs beautifully with the creamy potatoes.
• Swap Cheese: If you like it gooey and stringy, mozzarella works; for sharper flavor, a mix of Gruyère and cheddar is stunning.
• Go Dairy-Free: Using coconut cream and a dairy-free cheese substitute has worked surprisingly well for me, just expect a slightly different texture.
• Boost with Onion: For extra onion goodness, caramelize some onions and layer them in — it’s a game changer!

How to Make Creamy Potato Bake with Onion Soup Recipe

Step 1: Slice the Potatoes Super Thin

This step is where a mandolin shines. I used to slice potatoes by hand, and it took forever—and wasn’t always even. Using a mandolin (careful with those fingers!) will give you even slices that cook uniformly. Aim for about 2-3mm thickness. Thin slices help the potatoes get tender and soak up all that creamy goodness.

Step 2: Layer the Potatoes in Your Baking Dish

Once sliced, lay the potatoes evenly in your greased baking dish. Try to distribute them nicely so each layer is consistent—that way, every bite cooked through perfectly. No overlapping mounds but a snug, neat layer.

Step 3: Mix the Cream and French Onion Soup Mix

In a bowl, stir together the cream and the entire packet of French onion soup mix until fully combined. This mixture is the heart of the dish, so don’t skip or skimp here. Pour it slowly over the potatoes, letting it seep through the layers. If you want a bit more onion punch, you can add a pinch of garlic powder here too.

Step 4: Cover and Bake Until Tender

Cover the dish tightly with foil to trap the steam and bake in a preheated oven at 170ºC (340ºF) for about 1.5 hours. You’ll know it’s ready when the potatoes are fork-tender and that wonderful aroma fills your kitchen. Resist the urge to poke it too early—patience here really pays off.

Step 5: Top with Cheese and Finish Baking

Once the potatoes are cooked through, pull off the foil and sprinkle your grated tasty cheese evenly on top. Pop it back in the oven for about 15 minutes or until the cheese is melted and gently bubbling with those golden spots. If you want an extra crusty finish, you can switch the oven to grill/broil for the last 2-3 minutes—just keep a close eye so it doesn’t burn.

Step 6: Serve Immediately and Enjoy

This dish is best served hot right from the oven while the cheese is still oozy. It makes a perfect side or even a hearty vegetarian main on its own.

How to Serve Creamy Potato Bake with Onion Soup Recipe

Garnishes

I like to sprinkle freshly chopped parsley or chives on top just before serving. It adds a fresh pop of color and a mild brightness that compliments the rich creamy flavors beautifully. Sometimes a little cracked black pepper on top works wonders too.

Side Dishes

This Creamy Potato Bake with Onion Soup Recipe pairs perfectly with roast chicken, grilled steak, or even a simple green salad for a lighter meal. It’s also fantastic alongside steamed veggies or a fresh slaw to balance out the richness.

Creative Ways to Present

For special occasions, I love baking this in individual ramekins for a fancy touch, or layering thin slices in a pretty ceramic dish. Serving it with a side of caramelized onions on top or a sprinkle of toasted breadcrumbs adds texture and wow factor for guests.

Make Ahead and Storage

Storing Leftovers

After enjoying this creamy potato bake, I usually store leftovers in an airtight container in the fridge for up to 3 days. When reheating, cover with foil and warm in the oven to keep it creamy and avoid drying out.

Freezing

I’ve frozen this bake a couple of times with good results. Just cool completely, wrap tightly in plastic wrap and foil, and freeze. Thaw overnight in the fridge, then reheat gently in the oven until warmed through. The texture may soften a bit, but the flavors stay delicious.

Reheating

My favorite way to reheat is in the oven at 160ºC covered with foil, for about 20-25 minutes, to warm through without drying. Avoid microwaving as it can get rubbery or uneven, though it’s okay for a quick fix if you’re in a rush.
