Spicy Jalapeño Cheddar Mashed Potatoes with Chili Powder

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.

FAQ

Can I make these potatoes ahead of time?

Yes, prepare completely and refrigerate up to 1 day. Reheat gently on the stove with a splash of milk, stirring frequently.

How can I make these spicier?

Leave some jalapeño seeds in, add more chili powder, or substitute serrano peppers for the jalapeños.

What if I don't have little potatoes?

Use any waxy potato like Yukon Gold. Cut larger potatoes into chunks for even cooking.
