Helpful Tips

Choose the right potatoes: Russet potatoes become softer and more tender as they cook, while Yukon Gold potatoes hold their shape better and have a naturally buttery texture.

Add butter for extra richness: Stir a small pat of butter into the finished potatoes for a richer, smoother flavor.

Don’t add extra liquid: The canned mushrooms already provide moisture, so additional broth or water usually isn’t necessary.

Add black pepper: Freshly ground black pepper adds a simple burst of flavor that works especially well with the mushrooms and onion seasoning.

Make it a complete meal: Top the potatoes with a fried egg or serve them with sausage, roasted chicken, or another favorite protein.

Avoid overcooking: Start checking the potatoes toward the end of the recommended cooking time. You want them tender but not falling completely apart.
