Classic Flammkuchen With Creamy Topping
I kept spotting Flammkuchen on food blogs and thought, "What's all the fuss about?" One Friday, I finally tried it and wow. Think of it as a super-thin pizza with a creamy base, onions, and bacon. It's a German-French classic from Alsace, also called Tarte Flambée.
Traditionally, it's made with crème fraîche, but I like to mix things up: half crème fraîche, half Greek yogurt. Still rich, just a bit lighter. And I can't resist adding thyme. Onions and thyme? A match made in kitchen heaven.
When it's in the oven, the smell is unreal. The edges turn perfectly crisp, the bacon goes golden, and the creamy layer starts to bubble, and that's when you know it's ready. Slice it up, grab a salad or a cold drink, and dinner's done. Fast food, homemade style.
What Do You Need?
(Exact amounts in the recipe card below 👇)
- Crème fraîche: rich and creamy base. Swap for sour cream if needed.
- Greek yogurt adds freshness. Full-fat yogurt works too.
- Nutmeg, salt & pepper: simple seasoning that ties it all together.
- Bacon: smoky, crispy perfection. Try pancetta or turkey bacon if you like.
- Onions: soft, sweet, golden. Red onions give a milder flavor.
- Thyme: warm and aromatic, or use oregano or rosemary.
- Flammkuchen dough: thin, ready-made base. Pizza dough or puff pastry also works (just roll it thin).
What Do You Need?
You can find a printable recipe with a step-by-step description at the bottom of this blog.
- Step 1: Mix crème fraîche, yogurt, nutmeg, salt, and pepper in a bowl.
- Step 2: Fry bacon until crisp, remove it, then cook the onions in the same pan until soft and glossy.
- Step 3: Roll out the dough on parchment paper, spread the cream mixture, and top with bacon, onions, and thyme.
- Step 4: Bake for 12 minutes - golden, bubbling, irresistible.
Top Tips
- Store-bought dough keeps it stress-free - no kneading, no mess.
- For extra crispiness, bake straight on a pizza stone.
- Swap bacon for mushrooms if you want a veggie version.
- Keep the topping thin for that signature crunch.
- A quick drizzle of olive oil before serving? Game changer.
- Serve as dinner or cut into squares for appetizers.
