This Gordon Ramsay Potato Gratin is creamy and cheesy, with layers of thinly sliced potatoes baked to perfection. It’s a comforting side dish that everyone will love!
Honestly, it’s hard to resist those cheesy, golden edges. I always try to save some for later, but they disappear fast—definitely a family favorite! 🥔❤️
Making this gratin is simple! Just slice the potatoes, layer them, and pour on the creamy sauce. It’s a great way to impress guests without too much fuss!
Key Ingredients & Substitutions
Potatoes: Yukon Gold potatoes are my go-to for this gratin because they’re creamy and hold their shape well. You can use russet potatoes as a substitute, but they might yield a slightly drier texture. If you’re looking for something different, sweet potatoes can add a fun twist!
Heavy Cream & Milk: Heavy cream gives the gratin its rich taste. If you’re watching calories, whole milk can be used instead, though it will be less creamy. A non-dairy option like cashew cream can also work well for a vegan version. Just keep in mind, it changes the flavor slightly.
Cheese: Gruyère is amazing here for its meltiness and flavor. Mixing it with Parmesan adds an extra punch, so I recommend doing that! If you can’t find Gruyère, feel free to substitute with Emmental or aged cheddar for a different taste and texture.
Thyme: Fresh thyme brings a lovely aroma and flavor. Dried thyme can substitute in a pinch, but use a little less since it’s more concentrated. You could also try rosemary for a different herbal note.
How Do You Layer the Potatoes for the Best Texture?
Layering potatoes is key for achieving that perfect texture in your gratin. The goal is to ensure each slice gets enough cream and cheese. Here’s how to do it right:
- Start by overlapping the potato slices slightly in the baking dish. This helps them cook evenly and absorb the cream well.
- Don’t rush! Take your time layering to make sure everything is evenly distributed. It’s okay if they’re not perfectly neat; it enhances rustic charm.
- Pour the cream mixture carefully to cover the potatoes without disturbing your layers too much. This gives each slice that creamy goodness they need to bake perfectly.
Following these steps will ensure you have a beautifully layered, creamy gratin that everyone will enjoy!

How to Make Gordon Ramsay Potato Gratin
Ingredients You’ll Need:
For the Gratin:
- 2 lbs (900g) Yukon Gold or russet potatoes, peeled and thinly sliced
- 2 cups (500ml) heavy cream
- 1 cup (240ml) whole milk
- 3-4 garlic cloves, minced
- 1 tsp fresh thyme leaves, plus extra for garnish
- 1 1/2 cups (150g) grated Gruyère cheese (or a mix of Gruyère and Parmesan)
- Salt and freshly ground black pepper, to taste
- Butter (for greasing the dish)
How Much Time Will You Need?
This creamy and comforting potato gratin will take you about 15 minutes to prepare, with a total baking time of about 1 hour and 10 minutes. You’ll want to let it rest for about 10 minutes before serving. So, overall, plan for around 1 hour and 35 minutes from start to finish!
Step-by-Step Instructions:
1. Prepare the Oven and Dish:
Start by preheating your oven to 350°F (175°C). While it’s heating up, take a medium-sized gratin or baking dish and butter it thoroughly. This will prevent the gratin from sticking and add a bit of flavor!
2. Make the Cream Mixture:
In a saucepan over medium heat, combine the heavy cream, whole milk, minced garlic, and thyme leaves. Warm the mixture gently, making sure it doesn’t boil. Once warmed, season it with a generous pinch of salt and freshly ground black pepper.
3. Layer the Potatoes:
Now it’s time to layer your sliced potatoes! Place them in the prepared baking dish, slightly overlapping each slice. Try to make sure they’re distributed evenly throughout for the best cooking results.
4. Add the Cream Mixture:
Pour the warm cream mixture over the layered potatoes until they are just covered. This gives the potatoes the creamy goodness they need to bake perfectly.
5. Sprinkle with Cheese:
Top the potato layers with the grated Gruyère cheese. Evenly distribute it so every bite will be cheesy and delicious!
6. Bake the Gratin:
Cover the dish with aluminum foil and place it in the preheated oven. Bake for 45 minutes. After that, carefully remove the foil and continue to bake for another 25-30 minutes, or until the top is golden and bubbly, and the potatoes are tender when pierced with a knife.
7. Let It Rest:
Once it’s done baking, take the gratin out of the oven and allow it to rest for about 10 minutes. This helps the dish set, making it easier to serve!
8. Garnish and Serve:
Finally, garnish your creamy potato gratin with some fresh thyme leaves. Serve it warm as a delicious and cheesy side dish that’s sure to impress!
Enjoy your homemade Gordon Ramsay Potato Gratin, which is rich, creamy, and beautifully browned on top. It’s perfect for special occasions or as a comforting side for any meal!
Can I Use Different Types of Potatoes?
Yes! While Yukon Gold or russet potatoes are perfect for this gratin, you can also try using Yukon Gold for their creamy texture. Sweet potatoes can also be a fun twist if you’re looking for something different!
Can I Make This Recipe Ahead of Time?
Absolutely! You can prepare the gratin up to the point of baking. Just cover it with foil and refrigerate it for up to 24 hours. When ready to bake, allow it to come to room temperature before placing it in the oven, adding additional baking time if needed.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm it gently in the oven at 350°F (175°C) until heated through, or microwave it covered with a damp paper towel for a few minutes.
What Can I Serve with Potato Gratin?
This delicious gratin pairs well with a variety of main dishes such as roasted chicken, grilled steak, or a fresh salad. It’s a versatile side that complements both casual and formal meals beautifully!
