Oven Baked 4-Ingredients Pommes Boulangere
There’s something wonderfully comforting about a dish of thinly sliced potatoes and golden onions slowly baking together in the oven. This Oven Baked 4-Ingredients Pommes Boulangere is simple, rustic, and incredibly satisfying.
I love recipes like this because they prove you don’t need a long ingredient list to make something that tastes special. With just potatoes, onions, broth, and butter, you get layers of tender potatoes, sweet onions, and a beautifully savory flavor.
I made this one on a quiet weekend when I wanted a comforting side dish without making anything complicated. Once the butter melted into the onions and the broth started bubbling around the potatoes, the whole kitchen smelled amazing. By the time it reached the table, everyone was asking for a little more.
It’s especially wonderful alongside a Sunday roast, but honestly, these potatoes are good enough to steal the show on their own.

👩🍳 How to Make Oven Baked Pommes Boulangere
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly butter a 9×13-inch baking dish.
Step 2: Slice the Potatoes
Peel the potatoes and slice them thinly and evenly.
A mandoline makes this quick and easy, but a sharp knife works just as well.
Try to keep the slices close to the same thickness so they cook evenly.
Tip: Don’t rinse the sliced potatoes. Their natural starch helps the finished dish hold together.
Step 3: Cook the Onions
Melt 2 tablespoons of butter in a large skillet over medium heat.
Add the sliced onions and cook for about 8–10 minutes, stirring occasionally, until softened and lightly golden.
Season with a little salt and pepper if desired.
You don’t need to completely caramelize the onions because they’ll continue cooking in the oven.
Step 4: Layer the Potatoes and Onions
Arrange a layer of sliced potatoes across the bottom of the prepared baking dish.
Season lightly.
Add a layer of softened onions.
Continue layering potatoes and onions until all the ingredients have been used.
Finish with a layer of potatoes on top.
Step 5: Add the Broth and Butter
Slowly pour the broth around the edges of the baking dish.
The broth should come partway up through the potatoes without completely covering the top layer.
Dot the remaining 2 tablespoons of butter over the potatoes.
Step 6: Cover and Bake
Cover the baking dish tightly with aluminum foil.
Bake for approximately 40 minutes.
The covered baking time allows the potatoes to steam and absorb the flavorful broth.
Step 7: Uncover and Brown
Carefully remove the foil.
Return the dish to the oven and bake uncovered for another 25–30 minutes, or until the potatoes are completely tender and the top is golden brown.
For extra-crispy edges, give them a few additional minutes, keeping a close eye on the dish.
Step 8: Rest and Serve
Remove the potatoes from the oven and let them rest for 10 minutes.
This gives the remaining broth time to settle into the potatoes and makes the dish easier to serve.
Spoon onto plates and serve warm.
💡 Tips for Perfect Pommes Boulangere
Slice the Potatoes Thinly
Thin, evenly sized slices cook more consistently and create that beautiful layered texture.
Don’t Wash the Potatoes
The natural potato starch helps thicken the broth slightly and gives the finished dish a lovely cohesive texture.
Soften the Onions First
Cooking the onions before baking brings out their natural sweetness and gives the dish much more flavor.
Use Flavorful Broth
Since there are only four main ingredients, the broth makes a difference. Use a good-quality broth for the best flavor.
Don’t Overfill With Liquid
You want the potatoes to absorb the broth rather than swim in it. The dish should be moist and savory without being watery.
Let It Rest
Those final 10 minutes make a difference. The potatoes continue absorbing the liquid as they cool slightly.
🧈 Delicious Variations
Garlic Pommes Boulangere
Add a few minced garlic cloves to the onions while they soften.
Herbed Potatoes
Add fresh thyme or rosemary between the layers for a fragrant variation.
Deeply Caramelized Onion Version
Cook the onions slowly for 20–25 minutes until deeply golden before layering them with the potatoes.
Beef Broth Version
Use beef broth instead of chicken or vegetable broth for a deeper, richer flavor.
This is especially delicious served alongside roast beef.
Cheesy Version
For a less traditional but indulgent variation, sprinkle Gruyère or Parmesan over the top during the final 10 minutes of baking.
🍽️ What to Serve With It
These potatoes are perfect alongside hearty main dishes.
Try them with:
Roast beef
Roast chicken
Pork loin
Roast lamb
Grilled steak
Baked ham
Meatloaf
Green beans
Roasted carrots
They’re particularly good with roast beef because the potatoes soak up all those delicious meat juices.
🥡 Storage Instructions
Refrigerator
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for 3–4 days.
Reheating
For the best texture, reheat in a 350°F (175°C) oven until hot.
Cover loosely with foil if the potatoes are browning too quickly.
Individual servings can also be reheated in the microwave.
Freezing
Pommes Boulangere can be frozen, although the potatoes may become somewhat softer after thawing.
For the best texture, enjoy them fresh or refrigerated.

❓ Frequently Asked Questions
What is Pommes Boulangere?
Pommes Boulangere is a classic French-style potato dish made with thinly sliced potatoes, onions, and stock, traditionally baked until tender and golden.
Do I have to peel the potatoes?
No. Leaving the skins on gives the dish a more rustic appearance. Just scrub the potatoes thoroughly before slicing.
What potatoes are best?
Yukon Gold potatoes give a buttery, creamy texture, while russets become soft and fluffy. Either works well.
Can I use beef broth?
Yes. Beef broth gives the dish a richer savory flavor and works especially well with beef roasts.
Can I prepare it ahead of time?
Yes. You can assemble the dish several hours ahead, cover it, and refrigerate it until you’re ready to bake. It may need a little additional cooking time when starting cold.
Why are my potatoes watery?
There may have been too much broth, or the dish may not have baked uncovered long enough. Letting the potatoes rest after baking also helps them absorb some of the remaining liquid.
Can I make this dairy-free?
Yes. Replace the butter with a dairy-free butter alternative or another suitable cooking fat.

It’s humble enough for an ordinary family dinner but special enough for a holiday table. The potatoes become tender and buttery, the onions turn sweet and golden, and the broth gives everything a wonderful savory depth.
