Step 1
Heat 3 tbsp olive oil in a 12-inch skillet over medium-high heat until shimmering.
Step 2
Shred the potatoes and apple on a box grater. Thinly slice the onion. Toss with salt and pepper.
Step 3
Spread the potato-apple mixture in the skillet, pressing down. Cook until the bottom is golden and crispy, about 8 minutes. You'll smell it browning.
Step 4
Scatter cheese and thyme over the top. Swirl mustard with 2 tbsp water, then drizzle over.
Step 5
Flip in sections using a spatula (or slide onto a plate and flip back into the pan) and cook 4 more minutes until the second side is golden.
Step 6
Slide onto a cutting board. Let rest 2 minutes, then cut into wedges and serve hot.
