Common Mistakes to Avoid

When making the Best Ever Caramelized Onion Mashed Potatoes, a few common mistakes can lead to less-than-perfect results. Here are some pitfalls to avoid:

Boldly slicing onions unevenly: If your onions are not sliced evenly, they will cook at different rates. Aim for uniform slices for consistent caramelization.
Boldly rushing the onion caramelization: Caramelizing onions requires patience. Cooking them too quickly will result in burnt edges instead of sweet, golden goodness. Allow about 40-50 minutes on medium heat.
Boldly using cold ingredients: Adding cold butter or milk straight from the fridge can cool down your mashed potatoes. Make sure all ingredients are at room temperature for a creamy texture.
Boldly over-mashing the potatoes: Over-mashing can lead to gluey potatoes. Mash just until combined and smooth to maintain the ideal fluffy consistency.
Boldly forgetting seasoning: Under-seasoned potatoes can taste bland. Be sure to add enough salt and taste as you go to enhance flavors.
