Common Mistakes to Avoid
When making French Onion Potatoes, it’s easy to make a few common mistakes. Here’s how to steer clear of them:
- Skipping the Preheat: Always preheat your oven. Skipping this step can lead to uneven cooking and undercooked potatoes.
- Not Coating Evenly: Ensure you mix the sour cream mixture thoroughly. Uneven coating can result in dry spots on your potatoes.
- Using Wrong Potato Type: Opt for starchy potatoes like Russet or Yukon Gold. Avoid waxy potatoes, as they won’t give you that creamy texture.
- Overbaking Without Checking: Keep an eye on your dish during the last minutes of baking. Overbaking can turn your potatoes mushy instead of perfectly tender.
- Neglecting Seasoning: Don’t forget to season with salt and pepper. This enhances the flavor and brings out the richness of the dish.
