FAQs

1. Can I use sweet potatoes instead of regular potatoes?

Yes, sweet potatoes would work great in this recipe, adding a slight sweetness to balance the savory flavors.

2. Can I make this recipe without onion soup mix?

Yes, if you don’t have onion soup mix, you can use a combination of dried onion flakes, garlic powder, and a little salt to create your own seasoning blend.

3. Can I use a different type of oil?

Yes, you can substitute the canola and olive oils with vegetable oil, sunflower oil, or avocado oil.

4. How do I know when the potatoes are done?

The potatoes are done when they are golden brown and crispy on the edges, and easily pierced with a fork. The onions should also be tender and caramelized.

5. Can I make this dish ahead of time?

You can prepare the potatoes and onions, then store them in the refrigerator before roasting. When ready to cook, simply proceed with the roasting instructions.

6. Can I make this without garlic?

Yes, you can skip the garlic if you’re not a fan of its flavor. You could substitute with shallots or simply use extra rosemary for a more herbal flavor.

7. Can I use frozen potatoes for this recipe?

Fresh potatoes yield the best results for this recipe, but you can use frozen potatoes if needed. Just be sure to thaw them before roasting.

8. Can I cook this dish in a different pan?

Yes, you can use any oven-safe pan or baking sheet. Just make sure the potatoes are spread out in an even layer for uniform cooking.

9. How can I make the potatoes even crispier?

For extra crispy potatoes, try using a higher heat (450°F) and leaving the foil off during the final roasting stage. You can also flip the potatoes halfway through roasting to ensure they crisp up evenly.

10. Can I use dried rosemary instead of fresh rosemary?

Yes, you can use dried rosemary in place of fresh rosemary. Use about half the amount (1/2 tablespoon) since dried herbs are more concentrated.
