Let me tell you, the first time I made Mary Berryโs Chicken Tartiflette, I absolutely underestimated how indulgent this dish really is. I thought, โOh, just chicken, spuds, a bit of cheeseโsimple weeknight fare.โ Then I opened the oven and got walloped by the smell of bubbling Reblochon and crispy ham and immediately knew I was in trouble. The good kind.
But not everything went smoothly. I overdid the wine once (very Mary Berry of me, Iโd like to think), and ended up with a runnier sauce than I wanted. Another time, my potatoes were still a bit too firm. But once I got the timing rightโoh my days. Creamy, savoury, heartyโฆ and somehow still elegant.
So if your chicken tends to dry out or your sauce separates or youโre not sure when to add the cheeseโdonโt worry, Iโve done the wonky batch for you. Let me show you how to nail this.
The Secret Behind This Bake
Most tartiflette-style bakes throw everything in and hope for the best. This one? Itโs clever. You roast the potatoes and onions first, separately from the chicken, which stops the veg going mushy or greasy. Wrapping the chicken in ham keeps it juicy, while the cream, wine, and cheese bubble into this dreamy French-inspired sauce.
I didnโt think the mustard and lemon at the end would do muchโbut they absolutely lift the richness and stop it from feeling heavy. That tiny bit of sharpness is magic.
Also: donโt skip the mushrooms. They soak up the flavour like little sponges.
INGREDIENTS + WHY THEY MATTER
- Parma or Black Forest Ham โ Wraps the chicken and crisps up in the oven. I tested bothโBlack Forest gives a slightly smokier edge.
- New Potatoes โ Hold their shape better than floury spuds. Slice thick so they donโt fall apart.
- Reblochon Cheese โ The classic choice. Creamy, slightly nutty. I tried Brie onceโit worked, but was milder.
- White Wine โ Adds acidity and depth. Go dry, not sweet.
- Double Cream โ Donโt swap for singleโitโll split.
- Grainy Mustard + Lemon Juice โ Sounds odd, but trust meโit brightens everything.
- Fresh Thyme & Parsley โ Add right at the end for that fresh herby finish.
Making It Yours (Without Ruining It)
- Cheese swap: No Reblochon? Brie or Camembert are fine, just go for the riper, gooier ones. Gruyรจre works, but changes the vibe.
- Gluten-free: Naturally GFโjust double-check your mustard and ham.
- Dairy-free: I tried it once with Oatly cream and DF camembert. Texture held up, but flavour wasnโt quite the same.
- Veg additions: Spinach stirred in at the end is lovely. Roasted red peppers add sweetness. Avoid watery veg like courgetteโitโll mess up the sauce.
MISTAKES IโVE MADE (AND HOW TO AVOID THEM)
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Potatoes too firm | Didnโt pre-roast long enough | Roast at least 25 mins before adding chicken |
Sauce too runny | Too much wine or underbaked | Measure wine properly + donโt skip resting |
Cheese disappeared | Added it too early | Add just before second bake |
Chicken dry | Overbaked or no resting | Bake 20โ22 mins, rest 5 mins before slicing |
HOW TO MAKE MARY BERRYโS CHICKEN TARTIFLETTE
- Preheat oven to 200ยฐC (180ยฐC fan)/Gas 6.
- Roast the veg: Snip 2 slices of ham, toss with onions, sliced potatoes, garlic, olive oil, salt & pepper in a large roasting tin. Roast for 25 mins until potatoes start to soften.
- Wrap the chicken: Lay the remaining ham flat, top each with a chicken breast, and roll. Season well.
- Assemble: Remove tin from oven, stir in mushrooms, white wine, double cream, and diced cheese. Nestle chicken on top.
- Bake again: Return to oven for 20โ22 mins, or until chicken is just cooked and golden in spots.
- Rest and finish: Lift chicken onto a warm plate. Stir mustard, lemon juice, thyme, and parsley into the veg. Carve chicken and spoon over the sauce.

TIPS FROM MY KITCHEN
- I slice potatoes about 5mm thickโany thinner and they go too soft.
- I always rest the dish on a wooden board before servingโit thickens just enough in those 5 mins.
- Donโt skimp on seasoning. Potatoes need more salt than you think.
- I use a deep metal roasting tinโit crisps better than ceramic.
STORAGE + SERVING
- Fridge: Keeps well for 3 days. Reheat gently in oven or microwave with a splash of cream or stock.
- Freezer: Freeze portions in containers. Reheat from chilled for best textureโfully defrosted ones can get a bit soggy.
- Serve with: Steamed green beans, buttery peas, or a crisp green salad. Itโs rich, so something light helps.
FAQs โ Real Query Answers
Q: Can I make this without wine?
A: Yesโuse chicken stock instead. Youโll lose a bit of sharpness, so add an extra splash of lemon.
Q: Whatโs the best cheese if I canโt find Reblochon?
A: I like Brie or Camembertโmake sure theyโre ripe. You want gooey, not chalky.
Q: Can I prep this ahead?
A: You can roast the veg and wrap the chicken ahead. Keep them separate in the fridge and assemble just before baking.
Q: Is it very rich?
A: Yesโbut in the best way. I sometimes serve smaller portions with a big pile of greens.
Q: Can I use thighs instead of breasts?
A: You can! Boneless, skinless thighs work beautifullyโjust give them an extra 5 mins to cook through.
