Common Mistakes to Avoid

Making the Best Ever Caramelized Onion Mashed Potatoes can be simple, but there are a few common mistakes that can affect your results. Here are some tips to ensure your dish is perfect every time.

• Overcooking the Onions: If you cook the onions too quickly, they can burn instead of caramelizing. Cook them on medium heat and stir occasionally for even browning.
• Not Salting the Water: Failing to add salt to the boiling water for the potatoes can lead to bland mashed potatoes. Add a generous amount of salt to enhance flavor during cooking.
• Using Cold Ingredients: Adding cold butter or milk directly to hot potatoes can cool down your mixture. Warm these ingredients slightly before combining them with the potatoes.
• Skipping the Mashing Step: For creamy mashed potatoes, avoid skipping the mashing step after adding ingredients. Mash thoroughly to achieve a smooth texture.
• Neglecting Herbs and Seasoning: Don’t forget to incorporate fresh herbs and seasonings into your mashed potatoes. They add depth and flavor that elevate your dish.
