This homemade version of steakhouse-style Potatoes au Gratin takes basic items and turns them into a fancy side that's just as good as what you'd get at Ruth's Chris. With three kinds of cheese and tender potatoes, you'll end up with something so creamy and rich that it'll make any dinner feel extra special.
I've tweaked this dish many times to get it just right. The real trick is how you stack the flavors and getting the sauce thickness spot on. Nowadays my folks ask me to bring this to every family get-together during the holidays.
Key Ingredients Breakdown
- Russet potatoes: Go for ones that look the same size
- Heavy cream: Don't skimp on fat content
- Chicken stock: Try making your own if possible
- Fresh garlic: Skip the jar stuff completely
- Quality cheeses: Grate them yourself right before using
- Sweet onion: Gives a gentle background taste
- Fresh parsley: Adds a pop of freshness
Comprehensive Cooking Process
- Potato Preparation:
- Give them a good scrub. Take all the skin off. Cut into thin same-sized slices. Soak in cold water. Pat them dry. Work fast so they don't turn brown.
- Base Development:
- Let butter melt gently. Cook onions till they go clear. Toss in garlic carefully. Add salt and pepper thoughtfully. Mind your heat.
- Sauce Creation:
- Pour stock in bit by bit. Add cream without rushing. Keep it just barely bubbling. Watch how thick it gets. Taste and adjust seasonings. Keep heat low. Don't let it boil.
- Potato Cooking:
- Put slices in sauce one by one. Make sure they all get coated. Stir without breaking them. Test softness often. Keep heat just right. Put a lid on and check regularly.
- Final Assembly:
- Dump into baking dish. Spread cheese around nicely. Make sure it's all even. Get the sides covered too. Watch it turn golden. Sprinkle with herbs.

Whenever I bring this to the table, everyone wants to know how I made it. There's something really special about how the cream mingles with all those cheeses that just makes dinner feel fancy.
Managing Your Heat
Getting the temperature right matters a ton. If it's too hot, your cream sauce will separate and look weird. Too cool and your potatoes won't cook right. I aim for just barely bubbling the whole time.
Prep It Early
You can get this ready up to a day ahead of time. Just wrap it up and stick it in the fridge, then let it sit out a while before baking. You'll need to add about 10-15 more minutes in the oven if it's still cold.
