This potato bake with bacon is a perfect ‘posh’ side for your next Thanksgiving, Christmas, Easter, or even midweek meal! There’s no cream, but somehow it’s still creamy and delicious. Just layer up caramelised onions, thinly sliced potatoes, bacon and parmesan cheese and bake with stock for amazing buttery potatoes that are soft inside and lightly crispy on top!
What are boulangere potatoes?
The French have been making this layered potato bake, otherwise known as boulangere potatoes, for hundreds of years. And of course the French know a thing or two about classy and delicious food!
Way back when, people used to take their potato dishes to the local bakery to be cooked after the bakers had done baking their bread. Hence the name: boulangere potatoes, or baker’s potatoes.
What do they taste like? They’re a little like a potato gratin, or dauphinoise potatoes, which I also love. BUT with one main difference. NO CREAM.
But before you click away, without cream doesn’t mean any less delicious. These potatoes are perfectly cooked – soft and creamy on the inside without falling apart, with a little crisp on top. And then there’s the creamy, cheesy, super flavourful ‘sauce’ that goes so perfectly with any kind of meat.
Note that normally boulangere potatoes don’t contain any bacon or parmesan either. Without the bacon and parm you’ll still have a mighty tasty dish of potatoes! My recommendation? Keep them in there, of course.
Why you’ll love them
- NO CREAM. As the potatoes are cooked in a stock/broth instead of cream, this is lighter than a classic potato bake recipe. But it’s just as flavourful!
- THEY’RE VERSATILE – fancy enough to serve to guests but simple and easy enough for a family midweek meal.
- NO HARD-TO-FIND-INGREDIENTS. Make them with potatoes, bacon, parmesan cheese and a few other pantry ingredients in a few easy steps.
- EASY TO PREPARE AHEAD. You can either prepare the different layers ahead, then assemble later. Or you can cook the whole dish ahead and reheat when ready to serve.
- SUCH A CLASSY DISH! You can sound all fancy when you tell your guests (or family!) this is a traditional French dish called boulangere potatoes.
About the ingredients
You really don’t need anything fancy to make this dish:
Potatoes: What kind? Starchy potatoes such as Russets, Sebago, King Edwards, Maris Piper and Yukon Golds are great for any kind of potato gratin. However, general all-purpose potatoes work well too, such as Desiree which are waxy, floury and starchy all at the same time.
Bacon: Any kind, but smoked bacon will add the most flavour.
Onions: You’ll need 2 medium to large sliced onions. It sounds like a lot, but they’ll cook right down!
Butter: For caramelising the onions and dotting over the top of your potato bake.
Balsamic vinegar: Just a splash, to add to the cooked onions to make them even more sticky and sweet.
Parmesan cheese: Grated, for sprinkling between the layers of potato and on the top.
Mixed dried herbs: Use basil, oregano, thyme, or a mixture. I use mixed Italian style herbs.
Stock/Broth: You’ll pour this all over the potatoes before baking. Either vegetable or chicken works – just try to choose a good quality brand.
How to make a potato bake with bacon
Step 1: The first thing you do is pan fry some delicious bacon pieces for around 10 minutes until crispy.
Step 2: While your bacon is cooking, finely slice the potatoes. You can either use a mandolin or food processor for this step, or just slice with a sharp knife.
Step 3: Then you use the same pan you cooked the bacon in to CARAMELISE 2 whole onions in butter. I’ll leave you to imagine the flavour infusion!
Step 5: Lightly spray your casserole dish with oil or grease with butter to stop sticking.
Step 6: Layer up your potato casserole like a lasagna. Begin with a layer of potatoes, then scatter over a layer of onions, bacon, parmesan, herbs and pepper. Complete 2 more layers, then finish with a final layer of potatoes.
Step 7: Pour over the hot broth/stock before baking. Then dot all over with butter.
Step 8: Bake until most of the stock/broth has been absorbed, the potatoes are cooked and the potato bake has an irresistible crispy, cheesy top.
After letting rest for a short while, either serve immediately, cool and reheat later, or cool and freeze for another day.
Helen’s top tips
- Use a food processor or mandolin to slice the potatoes if you have either of these. They’re both quick and easy ways to get even slices.
- Before layering up your casserole, roughly divide the potatoes and cheese into 4, and the bacon bits and onions into 3. This way you don’t have to worry about running out of the yummy bacon and onions by the second layer!
- DON’T wash your peeled potatoes, or soak them in water. You don’t want to wash away any of the starch in the potatoes. You need it to work its magic in the oven and thicken up the yummy juice!
- Let the finished dish stand for 15 to 20 minutes before serving. This will give the potatoes time to absorb a little more of the delicious juice. They’ll also hold together a little better as you serve them.
- Garnish with a little fresh parsley just before serving (optional, but looks good!).
How to serve boulangere potatoes
If I’m making these potatoes for a family meal, I usually serve them with a supermarket rotisserie/cooked chicken and vegetables. Or, I make my own rotisserie chicken in my air fryer (only takes 1 hour). It’s the perfect ‘effortless’ meal. To make it even easier, make the potatoes ahead and keep them in the fridge or freeze them until ready to eat.
If you aren’t ready to eat your chicken just after you’ve bought it, or it’s a warmer day, you can even pop it into the fridge and serve it cold. I love the combination of the cold meat with the piping hot crispy cheesy potatoes!
But the beauty of boulangere potatoes is that they’re also posh enough to serve to guests. They can very easily serve 6 as a side dish to go with any kind of meat and vegetables you can think of.
They’d make a perfect Thanksgiving, Christmas or Easter side dish! You can even cook them ahead and freeze them until the big day.
More things to know (recipe FAQ)
The best kind of potatoes to use for any kind of potato bake is starchy ones. The starch will thicken up the juices as the casserole bakes. Some examples of starchy potatoes are Desiree, King Edwards, Maris Piper, Russets, Gold Rush, Golden Wonder, and Vivaldi.
If you aren’t sure which potatoes are starchy where you live, just use a good all-purpose variety, which are also good for potato gratins and bakes. Yukon Golds, Sebago, white potatoes and purple potatoes are all examples of all-purpose potatoes.
Yes, no problem at all! It’s very quick and easy to slice them with a food processor attachment or mandolin. But if you don’t have either of these, slicing by hand is fine too.
Just slice 3 to 4 mm thick slices as evenly as you can, but don’t worry about getting them perfect. Just slice quickly and confidently with a small sharp knife. You’re only slicing 5 or 6 potatoes so it won’t take too long.
Definitely! You can either layer up the casserole and pop it into the fridge or freezer until ready to bake. Then when you’re ready to cook it, pour over the hot stock, dot butter over the top and bake.
OR you can bake the potatoes, then let them cool and pop them into the fridge (or freezer!) until ready to eat them. If you’re going to freeze them, let cool completely, then wrap the whole dish in several layers of plastic wrap and foil before freezing.
You can freeze for up to 3 months. When you want to serve your potatoes, simply defrost completely (if frozen!) and reheat for 30 minutes at 355F/200C.
