30-Minute Spicy Jalapeño Cheddar Mashed Potatoes

Creamy mashed potatoes get a bold upgrade with diced jalapeños, melted cheddar cheese cubes, and smoky chili powder. The jalapeños add a fresh heat that balances beautifully with the rich, tangy cheddar, while the chili powder brings an earthy depth. Perfect as a side dish for barbecues, holiday meals, or any time you want to transform ordinary mashed potatoes into something special. The little potatoes create a naturally creamy texture when mashed with warm milk and butter.
