French onion roasted potatoes FAQ:

What type of potatoes work best for this recipe?

Russet or Yukon Gold potatoes are ideal for French Onion Roasted Potatoes due to their starchy texture, which helps them become tender and crispy during roasting.

How can I tell when the potatoes are done roasting?

The potatoes are done when they are golden brown and crispy on the outside. You can test for doneness by piercing them with a fork; they should be tender inside.

Can I make substitutions for the butter in this recipe?

Yes, you can use olive oil or a vegan butter alternative if you prefer a dairy-free option. However, using butter adds rich flavor, so choose a substitute that you enjoy.

How should I store leftovers?

Store any leftover French Onion Roasted Potatoes in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for best results to regain crispiness.

What adjustments should I make for a smaller batch?

For a smaller batch, simply reduce the quantity of potatoes and other ingredients proportionally. Halve the recipe if you want to serve 2-3 people.

Tips:

- Choose potatoes that are relatively uniform in size for even roasting.

- Cut the onions finely to ensure they caramelize well and blend seamlessly with the potatoes.

- For a richer flavor, consider adding a splash of beef broth or a sprinkle of thyme before roasting.

- Line your baking sheet with parchment paper or lightly oil it to prevent sticking.

- Stir the potatoes halfway through roasting to ensure they cook evenly and develop a golden, crispy exterior.
