There is something especially satisfying about pulling a puff pastry tart from the oven when the edges have risen into crisp, golden layers and the cheese is still bubbling underneath.

This Bacon, Potato & Mozzarella Puff Pastry Tart combines thinly sliced potatoes, smoky bacon and creamy mozzarella on a flaky puff pastry base. It looks impressive enough for weekend brunch, but the actual prep takes about 15 minutes.

• Save

Serve it with a crisp green salad for lunch or a light dinner, add it to a brunch spread, or cut it into smaller squares and turn it into an easy party appetizer.

And if puff pastry is already one of your favorite shortcuts, you're in good company around here. My Crispy Puff Pastry Sticks with Cheese, Bacon and Spices and Savory Puff Pastry Bites with Caramelized Onions and Mushrooms use that same flaky pastry in completely different ways.

❤️ Why You'll Love This Bacon and Potato Tart

What makes this tart work isn't a complicated ingredient list. It's the contrast between the layers.

You get crisp, buttery pastry around the edges, creamy melted mozzarella underneath, tender potatoes on top and little hits of smoky bacon throughout.

It's also remarkably versatile. The original recipe was designed for brunch, appetizers, light dinners and casual entertaining.

If you like savory brunch recipes, this would fit beautifully beside my Quiche with Ham and Cheese or Potato-Crusted Frittata. For something completely different but equally good for entertaining, try my Mini Caprese Pizzas on Naan.

🛒 Ingredients You'll Need to Make Bacon, Potato & Mozzarella Tart

One of the best things about this recipe is how short the ingredient list is.

Potatoes

You'll need 3 medium potatoes, thinly sliced.

Thin is important here. The potatoes have to become tender during roughly the same amount of time it takes the puff pastry to become golden and crisp.

Puff Pastry

Use 1 sheet ready-made puff pastry.

There's no need to make pastry from scratch. Store-bought puff pastry gives us those dramatic flaky layers with very little prep.

Bacon

You'll need 150 g bacon, sliced.

Bacon brings both smoky flavor and saltiness, so be conservative when adding extra salt later.

Mozzarella

Use 100 g mozzarella, sliced or shredded.

Mozzarella melts into a creamy layer underneath the potatoes without overpowering them.

Olive Oil

You'll need 3 tablespoons olive oil for drizzling over the tart.

Salt & Black Pepper

Season to taste.

Because the bacon already contains plenty of seasoning, I recommend going lighter on the salt and adding more after baking if needed.

Those are the seven ingredients specified in the original recipe.

🌿 Easy Flavor Upgrade: Fresh thyme or rosemary works especially well with potatoes. Parmesan or smoked mozzarella are also suggested variations if you want a stronger flavor.

👩‍🍳 How to Make Bacon, Potato & Mozzarella Puff Pastry Tart

Step 1 — Prepare the Potatoes

Slice the potatoes thinly and place them in a bowl of cold water for 10 minutes.

• Save

🧠 Why Are We Soaking the Potatoes?

This little step actually matters.

Soaking removes some of the excess starch from the surface of the sliced potatoes. More importantly for our tart, once they're drained we can get those slices really dry before they touch the pastry.

And puff pastry does not particularly enjoy wet toppings.

Drain the potatoes thoroughly and pat them dry with a clean kitchen towel or paper towels.

⚡ Flash Tip: Don't skip the drying. The goal is tender potatoes sitting on crisp pastry—not potatoes steaming over a damp pastry base.

---

Step 2 — Prepare the Puff Pastry

Preheat the oven to 400°F (200°C).

• Save

Place the puff pastry on a parchment-lined baking sheet and prick the surface with a fork.

🧠 Why Prick Puff Pastry With a Fork?

We want the pastry to puff dramatically around the tart, but we don't want the entire center ballooning underneath our toppings.

Pricking the center helps control that rise while still allowing those beautiful flaky layers to develop.

If you enjoy working with puff pastry, my Raspberry Puff Pastry Jam Turnovers show just how differently the same pastry behaves when it's folded around a filling rather than baked flat like this tart.

---

Step 3 — Add the Bacon

Arrange the sliced bacon evenly over the puff pastry.

• Save

Spread it out rather than concentrating it in one area. That way every slice gets some of that smoky bacon flavor.

---

Step 4 — Add the Mozzarella

Scatter 100 g mozzarella evenly over the bacon.

Notice the order here:

• Save

pastry → bacon → mozzarella → potatoes

That's useful.

The mozzarella melts underneath the potatoes, giving the tart a creamy layer without completely burying the potatoes in cheese.

---

Step 5 — Layer the Potatoes

Arrange the drained and thoroughly dried potato slices over the mozzarella.

• Save

Slightly overlapping them gives the tart that beautiful layered appearance, but don't build several thick layers.

🔥 The Potato Thickness Matters

This tart is essentially a race between two things:

Will the potatoes become tender before the pastry gets too dark?

Thin, relatively uniform slices solve that problem. Thick potato slices can still be firm when the pastry is already perfectly baked.

A mandoline can make this easier, but a sharp knife works too.

---

Step 6 — Season the Tart

Drizzle the tart with olive oil, then season with salt and freshly ground black pepper.

• Save

If you're adding fresh thyme or rosemary, scatter it over the tart before baking.

Don't get heavy-handed with the salt. Between bacon and mozzarella, we already have plenty of savory flavor happening.

---

Step 7 — Bake Until Golden

Bake at 400°F (200°C) for 25–30 minutes, or until the potatoes are tender and the pastry is golden brown.

👀 Don't Watch Only the Clock

Twenty-five minutes is a guide.

The better test is what the tart looks like.

You want:

• deeply golden, visibly flaky pastry edges
• tender potatoes
• melted mozzarella
• bacon beginning to crisp

If the pastry still looks pale, give it a little more time.

⚡ Flash Tip: Puff pastry tells you when it's ready. Look for crisp, separated golden layers around the edges rather than relying exclusively on the timer.

---

Step 8 — Rest, Slice & Serve

Let the tart cool slightly before cutting it into portions.

• Save

That short rest gives the melted cheese a chance to settle and makes cleaner slices much easier.

Then get it to the table while that pastry is still beautifully crisp.

---

⭐ The Secret Is Controlling Moisture

If there's one thing that separates a beautifully crisp potato puff pastry tart from a disappointing one, it's moisture management.

Potatoes contain moisture. Mozzarella contains moisture. Bacon releases fat as it cooks.

Meanwhile, we're asking puff pastry to become crisp underneath all three.

That's why seemingly small details—drying the soaked potatoes thoroughly, keeping the potato layer relatively thin and avoiding excessive toppings—make such a difference.

More isn't necessarily better with a puff pastry tart.

Give the pastry room to do what it does best: puff, separate into layers and become crisp.

---

🥔 Do You Have to Soak the Potatoes?

For this recipe, I would.

The source specifically calls for soaking the thinly sliced potatoes in cold water for 10 minutes to remove excess starch.

The important follow-up is drying them thoroughly.

If you're short on time, it may be tempting to pull dripping potato slices straight from the bowl and start layering. That's exactly the extra moisture we don't want sitting above the pastry.

---

🧀 Can I Use a Different Cheese?

Yes, although mozzarella is particularly good here because it's mild and melts beautifully without taking over the tart.

The original recipe specifically suggests smoked mozzarella for a richer flavor and Parmesan as an additional flavor boost.

• Save

You could also combine mozzarella with a small amount of Parmesan rather than replacing it completely.

---

🌿 Easy Variations

Once you've made the basic tart, it's easy to take the same idea in different directions.

Fresh thyme: A natural match for potatoes and the garnish shown in several of the finished tart images.

Rosemary: Adds a more pronounced savory, woodsy flavor.

Parmesan: Sprinkle a little over the tart for an extra savory edge.

Smoked mozzarella: Reinforces the smoky bacon flavor.

These aren't additions I'm inventing for the recipe—the original specifically suggests thyme or rosemary, Parmesan and smoked mozzarella as variations.

---

🥗 What to Serve With Bacon, Potato & Mozzarella Tart

Because the tart is rich, buttery and savory, something fresh alongside it works beautifully.

A simple green salad is the easiest pairing and is also the serving suggestion given with the original recipe.

For brunch, you could serve smaller slices alongside my Kicked Up Egg Salad Sandwiches or High Protein Breakfast Egg Wrap.

And if you're putting together an appetizer spread, my Easy Bacon Wrapped Shrimp would take the menu in a completely different direction while keeping that smoky bacon theme going.

---

📦 Storage & Reheating

If you have leftovers, let the tart cool before refrigerating it in an airtight container.

The refrigerator isn't puff pastry's best friend—it gradually softens those crisp layers—so reheating matters.

For the best texture, reheat the tart in the oven or air fryer until warmed through and crisp again rather than relying on the microwave.

The microwave will warm it, but it won't bring back that flaky pastry texture.

⚡ Flash Tip: If crisp pastry is the priority, reheating with dry heat is the way to go.

❓ Bacon, Potato & Mozzarella Tart FAQs

Can I make this tart ahead of time?

You can prepare the components ahead, but for the crispest puff pastry, I prefer assembling and baking the tart closer to serving time.

Why did my puff pastry turn soggy?

Too much moisture is the likely culprit. Thoroughly dry the potatoes after soaking, avoid excessively thick toppings, and bake until the pastry is properly golden rather than simply stopping when the timer goes off.

How do I know when the potatoes are cooked?

Pierce one of the potato slices with the tip of a knife. It should feel tender rather than firm.

Can I serve potato puff pastry tart cold?

You can, but this particular combination is at its best warm, when the mozzarella is soft and the pastry still has some crispness.

Can I make smaller appetizer portions?

Absolutely. The original recipe specifically positions the tart as an appetizer as well as a brunch or light-dinner recipe.

Bake the tart whole and cut it into smaller squares for serving.
