Ingredients for Slow Cooker French Onion Potatoes
Simple 4-Ingredient Recipe
- 3 pounds Yukon Gold potatoes, thinly sliced
- 2 packets dry French onion soup mix
- ½ cup unsalted butter, melted
- 2 cups shredded Gruyère cheese, divided
These simple ingredients create incredible comfort food flavor with very little effort.
Why Yukon Gold Potatoes Work Best
Yukon Gold potatoes hold their shape while staying creamy and tender.
Additionally, their buttery flavor pairs perfectly with Gruyère cheese and French onion seasoning.
Leaving the skins on also adds texture and saves prep time.
How to Make Slow Cooker French Onion Potatoes
Step 1: Prepare the Slow Cooker
Spray a 4- to 6-quart slow cooker with nonstick cooking spray.
This helps prevent sticking and makes cleanup easier afterward.
Step 2: Slice the Potatoes
Wash the Yukon Gold potatoes thoroughly.
Slice them into thin rounds about ⅛ to ¼ inch thick.
Thin slices cook more evenly and absorb flavor better.
If the potatoes feel very wet, pat them dry with a clean towel.
Step 3: Make the Onion Butter Mixture
In a medium bowl, whisk together:
- Melted butter
- French onion soup mix
Mix until fully combined and evenly moistened.
This mixture creates rich onion flavor throughout the dish.
Step 4: Layer the Potatoes
Spread a thin layer of sliced potatoes across the bottom of the slow cooker.
Next, drizzle some onion butter mixture over the potatoes.
Then sprinkle a handful of Gruyère cheese on top.
Continue layering until all ingredients are used.
Finish with the remaining cheese on top for extra melt and golden color.
Cook Until Tender and Cheesy
Cover the slow cooker with the lid.
Cook on:
- LOW for 6 to 7 hours
or - HIGH for 3 to 4 hours
The potatoes should become fork-tender while the cheese melts beautifully.
Optional Golden Cheese Finish
For an extra steakhouse-style finish, transfer the slow cooker insert under the broiler for 2 to 3 minutes if oven-safe.
The cheese develops crispy golden edges and deeper flavor.
Best Tips for Perfect French Onion Potatoes
Slice Potatoes Evenly
Uniform slices ensure even cooking throughout the dish.
A mandoline slicer works especially well for consistency.
Don’t Skip Gruyère Cheese
Gruyère melts smoothly while adding nutty, savory flavor.
It creates the classic French onion taste that makes this recipe special.
Avoid Overcrowding
Layer potatoes evenly for the best texture and flavor distribution.
Use Fresh Cheese
Freshly shredded cheese melts better than pre-packaged varieties.
As a result, the potatoes become creamier and richer.

The spice contrasts beautifully with the creamy cheese.
How to Store and Reheat Leftovers
Refrigerator Storage
