- Ensure your potatoes are uniform in size for even cooking when making French Onion Smashed Potatoes.
- When caramelizing onions, keep the heat at medium to avoid burning, and stir frequently for the best results.

French Onion Smashed Potatoes Recipe FAQs
How do I select the best russet potatoes for this recipe?
Absolutely! Look for russet potatoes that are firm with smooth skin and few blemishes. Avoid those with dark spots or any signs of sprouting, as these may be past their prime and can affect the dish’s texture. The ideal potatoes should feel heavy for their size, which indicates freshness and moisture.
What is the best way to store leftover French Onion Smashed Potatoes?
Very straightforward! Store your leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, reheat in the microwave or oven. If reheating in the oven, sprinkle a little cream over the top to keep them moist; this will enhance their deliciousness!
Can I freeze French Onion Smashed Potatoes?
Absolutely! To freeze, portion the potatoes into airtight containers or heavy-duty freezer bags, ensuring all the air is pressed out. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy, simply thaw them overnight in the fridge, and then reheat them for about 20-25 minutes at 350°F in a covered baking dish to retain moisture.
What if my onions don’t caramelize?
If your onions aren’t turning that lovely golden-brown hue, don’t fret! First, ensure your heat is set to medium; too high of a heat will burn them instead of caramelizing. Stir them often and allow plenty of time—about 15-20 minutes—to develop their sweetness. If they start to stick, a splash of water or broth can help!
Are there any dietary considerations I should be aware of?
Great question! This recipe contains dairy, specifically heavy cream and Gruyère cheese, so it may not be suitable for those with lactose intolerance or dairy allergies. For a dairy-free option, you might replace these with a combination of coconut cream and nutritional yeast for a cheesy flavor without dairy. Always check with guests regarding allergies before serving!
Can I make this dish vegan?
Very much so! To create a vegan version of French Onion Smashed Potatoes, simply substitute the butter with a vegan alternative, use non-dairy cream instead of heavy cream, and replace the Gruyère cheese with a plant-based cheese or nutritional yeast. The flavors will still shine through and make for a delicious dish!
