These oven baked fiesta potatoes are the kind of low-effort side dish that earns a regular spot in warm-weather menus and easy weeknight dinners alike. With diced red potatoes, jarred chunky mild salsa, shredded cheese, and a simple seasoning staple, the casserole dish does most of the work, turning a handful of pantry and refrigerator ingredients into a colorful, comforting bake with plenty of Tex-Mex style appeal.

Serve these potatoes alongside burgers, grilled chicken, steak, sausages, or barbecue for a cookout-friendly spread. They also pair nicely with scrambled eggs for brunch, or with black beans, sour cream, sliced avocado, and a simple green salad if you want to turn them into a more complete meal.

Ingredients

2 pounds red potatoes, diced into bite-size pieces

1 1/2 cups jarred chunky mild salsa
2 cups shredded Mexican blend cheese
1 tablespoon taco seasoning

Directions

1. Preheat the oven to 400°F and lightly grease a 9-by-13-inch casserole dish.

2. Add the diced red potatoes to the casserole dish and spread them into an even layer.

3. Sprinkle the taco seasoning over the potatoes, then pour the chunky mild salsa evenly across the top and stir gently to coat.

4. Cover the dish tightly with foil and bake for 35 minutes, until the potatoes are beginning to turn tender.

5. Remove the foil, sprinkle the shredded cheese evenly over the potatoes, and return the dish to the oven for 10 to 15 minutes, until the cheese is melted and the potatoes are fully tender.

6. Let the potatoes rest for 5 minutes before serving so the cheese can settle slightly and the casserole is easier to scoop.

Variations & Tips

Add fresh garnish: A sprinkle of sliced green onions, chopped cilantro, or a spoonful of sour cream added after baking gives the casserole a fresher finish and makes the flavors pop a bit more.

Make it spicier: If you want more heat, swap the mild salsa for medium or hot salsa, or add a pinch of crushed red pepper or diced pickled jalapeños before baking.

Use the right potato size: Try to dice the red potatoes into evenly sized pieces so they cook at the same rate. Smaller cubes bake more quickly and absorb the salsa mixture better.

Parboil for extra speed: If you're short on time, simmer the diced potatoes for 5 to 7 minutes first, drain well, and then assemble the casserole. This can shorten the oven time and help guarantee a tender center.

Change the cheese: Mexican blend is convenient, but cheddar, Monterey Jack, or pepper jack all work well here depending on whether you want a milder or sharper finish.
