Fondant Scalloped Potatoes
Progress saves automatically on this device.
Step 1
Peel the potatoes. Cut the uneven ends off each potato, then cut each potato into thirds, approximately 1 inch thick. Using a 2-inch round cutter, cut each piece into a cylinder. Save the potato trimmings for hash browns. Pat the cylinders thoroughly dry with paper towels.
Step 2
Heat an ovenproof pan over medium heat. Reserve a little of the measured avocado oil to grease the casserole, then add the remainder to the pan. Add potato rounds, leaving at least 1 inch between them; work in batches as necessary. Sear both flat sides until lightly golden, allowing about 3–5 minutes per side as a guide. Season with kosher salt and black pepper. The centers will still be uncooked.
Step 3
Rub the reserved avocado oil over the bottom of an ovenproof casserole dish. Arrange the potatoes evenly in a single layer. Set aside and preheat the oven to 350°F.
Step 4
In a separate saucepan, sauté the shallots in the 1 tablespoon butter over medium-low heat until translucent, about 3–5 minutes. Add the garlic and sauté for 1 minute.
Step 5
Add the heavy cream, whole milk, tarragon, nutmeg, Dijon mustard, measured salt and white pepper. Simmer gently for 2 minutes. Turn the heat to low and whisk in ½ cup Gruyère and all the Parmesan until melted. Reserve the remaining ¼ cup Gruyère for the top; avoid boiling the cheese sauce.
Step 6
Pour the cheese sauce over the potatoes and top with the remaining Gruyère. Cover the casserole and bake at 350°F for 30 minutes.
Step 7
Remove the cover and scatter the fried onions over the top. Bake uncovered for about 15 more minutes, until the sauce bubbles and a thin knife slides easily into the center of the thickest potato. If the potatoes need longer, loosely shield the topping with foil and continue until tender. Serve hot.

My potatoes will not brown.
Dry the rounds again, preheat the pan over medium heat, and sear in batches without crowding.
Why: Surface moisture or a crowded, cool pan causes steaming.
Watch for: A lightly golden crust; avoid overheating the oil.
The potatoes stick when I try to turn them.
Leave them undisturbed another minute, then gently loosen with a thin spatula. Check there is a film of oil.
Why: Turning before the crust forms can tear the surface.
Watch for: Do not force a stuck round or gouge the pan.
The outside is dark but the center is raw.
Lower the pan heat. Transfer lightly golden rounds to the casserole; the covered bake cooks the centers.
Why: The sear is for color rather than cooking through.
Watch for: Trimmed rounds should be 1 inch thick, not 2 inches tall.
My garlic browned too quickly.
Start the aromatics again if the garlic is burned; keep medium-low heat and add garlic only after shallots soften.
Why: Garlic burns faster than shallots.
Watch for: Fragrant garlic after about 1 minute, without dark brown flecks.
The cheese sauce looks grainy.
Remove from heat and whisk gently; a small splash of warm milk may help it come together. Resume only gentle heat.
Why: High heat or slow-melting coated grated cheese can destabilize the sauce.
Watch for: Do not boil vigorously after adding cheese.
The sauce seems too thin before baking.
Use the measured dairy and cheeses and proceed with the covered bake; the sauce is initially pourable. Do not add unlisted flour automatically.
Why: This is a cheese-and-cream sauce without a roux; it reduces during baking.
Watch for: Potatoes in one layer with sauce around them, not a deep stack.
The potatoes are still firm after 45 minutes.
Loosely shield the onions with foil and continue baking, checking every 5–10 minutes until a thin knife enters easily.
Why: Uneven thickness, a crowded dish or oven variation can extend cooking.
Watch for: Test the largest center pieces; a browned top alone is not doneness.
The fried onions are getting too dark.
Loosely cover the top with foil while the potatoes finish; next time add onions only for the final uncovered stage.
Why: Early topping or strong top heat browns onions before potatoes soften.
Watch for: Golden crisp onions rather than black edges.
My sauce tastes too salty.
Stop adding salt. Taste with a piece of potato; a little unsalted warm milk can soften the impression, but will thin the sauce.
Why: Cheeses, mustard and packaged onions already contribute sodium.
Watch for: Do not add more cheese or salted broth as a correction.
The leftovers are dry when reheated.
Add a small splash of milk, cover and warm gently to 165°F in the center; uncover briefly at the end.
Why: Cold potato starch and dairy sauce firm during refrigeration.
Watch for: Reheat only the needed portion and avoid prolonged hard boiling.
Substitution: ¾ cup Gruyère
Use ¾ cup freshly grated Emmental.
Divide ½ cup into the sauce and ¼ cup on top as written; milder and less nutty. Proposed alternative.
Substitution: ¼ cup Parmesan
Use ¼ cup finely grated Grana Padano.
Melt over low heat. Flavor and saltiness vary; taste the sauce. Proposed alternative.
Substitution: 2 tablespoons minced shallots
Use 2 tablespoons finely minced yellow onion.
Cook until fully translucent; onion can taste sharper and may need a little longer. Proposed alternative.
Substitution: ¼ teaspoon dried tarragon
Use ¾ teaspoon finely chopped fresh tarragon.
Add with the dairy as directed; fresh herb flavor may be brighter. Proposed alternative.
Substitution: 2 tablespoons avocado oil
Use 2 tablespoons refined olive oil suitable for sautéing.
Reserve a little for the casserole and use the remainder for searing. Flavor will vary; do not change the butter. Proposed alternative.
