Cheesy Sweet Potato Skillet Bake in One Cast Iron Pan

Sweet potato cubes, red bell pepper and a generous blanket of melting white cheese, all baked together in one cast iron skillet. The top turns golden and bubbling while the vegetables soften underneath.

It is a skillet dinner built for sharing straight from the pan, with tortilla chips for dipping and fresh cilantro and sliced red chili to finish. Few ingredients, one pan, and very little cleanup.

This cheesy sweet potato skillet bake brings together a few simple ingredients in one cast iron pan. Diced sweet potato and red bell pepper form a sweet, tender base, while a creamy cheese sauce coats every cube and melts into a silky layer. A final pile of shredded melting cheese bakes until golden at the edges, so the skillet arrives at the table bubbling.

Fresh cilantro, sliced red chili and whole jalapeños add brightness and heat, and a small bowl of chopped garnish sits beside the pan for anyone who wants more. The method is straightforward: dice, grate, layer, season, top and bake. Serve it as a casual dinner or a shared centrepiece for a relaxed evening with friends and family.

Ingredients

Why this recipe works

The sweet potato needs a long, steady bake to turn tender all the way through. Cutting it into even cubes lets every piece cook at the same pace, so no cube stays firm while another turns mushy. Layering the vegetables flat in the skillet gives the heat direct contact with the base and helps the sauce settle into the gaps between the pieces.

The cheese does two jobs in this dish. Mixed into the cream, it becomes a smooth sauce that coats the vegetables and keeps them moist during baking. The shredded topping then melts on the surface, bubbles and browns at the edges.

Grating the cheese yourself from a block gives a cleaner melt than pre-shredded packs, which often contain anti-caking starch that slows the process and can leave a slightly grainy texture.

Notes and substitutions

Choose a white melting cheese such as Monterey Jack or Oaxaca for the sauce and the topping. These cheeses melt smoothly, stretch well and stay creamy when they cool slightly, which is exactly what you want for dipping. Avoid aged, hard cheeses, which tend to turn oily or grainy under heat. If you cannot find these, mozzarella or Chihuahua cheese work well as substitutes.

A 10-inch cast iron skillet is the ideal size for this recipe: it holds the sweet potato in a single layer and retains heat so the cheese keeps bubbling at the table.

Use a chef's knife and a sturdy wooden cutting board for the dicing, and a box grater for the cheese. If you do not have cast iron, a similarly sized oven-safe skillet or a shallow baking dish will also work, though the top may brown a little less quickly.

• Monterey Jack or Oaxaca cheese: Other white melting cheese such as mozzarella or Chihuahua cheese, grated fresh for the smoothest melt.
• Heavy cream: Half-and-half for a lighter sauce, which may need a few extra minutes to thicken as it bakes.
• Red chili rounds: Pickled jalapeño slices or a pinch of crushed red pepper flakes for a milder heat.
