FAQs

How do I get the potatoes extra crispy?

Spread them in a single layer without crowding the pan and roast at high heat. Tossing them with a little cornstarch before roasting can also help.

Can I make the onions ahead of time?

Yes, caramelized onions store well and can be made a day or two in advance.

What if I don’t have sour cream or yogurt?

You can use crème fraîche, mayonnaise, or a mix of tahini and lemon juice as a substitute.

Are caramelized onions sweet?

Yes, they become naturally sweet as the sugars in the onion break down during slow cooking. A pinch of sugar speeds up the process.

What can I serve this with?

It pairs beautifully with grilled meats, roasted chicken, baked tofu, or a fresh salad.

Can I make this dish vegan?

Absolutely—use olive oil instead of butter and a plant-based cream or yogurt alternative.

Is this dish gluten-free?

Yes, it’s naturally gluten-free. Just confirm all condiments and toppings are certified GF if needed.

Can I use red onions?

Yes, though they’ll produce a slightly different flavor—sweeter and more colorful.

Can I add heat?

Yes, a pinch of chili flakes in the cream or smoked paprika on the potatoes will bring a little spice.
