Queso Fundido Skillet with Sweet Potato, Peppers and Melted Cheese

Melted cheese that stretches for inches, tender sweet potato, and a bright bite of red pepper and green chili, all baked in one cast iron skillet. This queso fundido skillet is built for sharing straight from the pan, with crusty bread for tearing and scooping. It comes together with simple chopping, a box grater, and a single oven stage, so the table is ready as soon as the cheese bubbles.

Queso fundido is traditionally a bowl of melted cheese served with warm tortillas, but this version turns the idea into a hearty skillet bake. Diced sweet potato, bell pepper, and green chili are cooked briefly in a savory tomato sauce base, then covered with a generous layer of firm melting cheese and baked until the cheese is golden and the sweet potato is tender.

The finished dish is served hot, with fresh cilantro and bright pieces of red pepper scattered across the bubbling surface. Every step happens in one pan, which keeps cleanup short and the flavors concentrated, and the result works as a casual dinner for four or as a shared starter for a gathering around the table.

Ingredients

Why this recipe works

The method starts with the vegetables cooked in the sauce base before the cheese goes on. Sweet potato releases starch and sugar as it heats, so stirring it with the tomato sauce and cumin lets the flavors soak in and coats each cube.

Cooking the vegetables in the skillet first also means they are partly tender before the bake, so the sweet potato finishes at the same time the cheese melts instead of staying firm in the middle.

The cast iron skillet holds heat evenly and moves easily from the stovetop to the oven, which is why it suits this dish so well. The heavy base keeps the sauce gently bubbling while the vegetables are coated, and the oven then surrounds the cheese with steady dry heat.

That heat melts the shreds into one smooth layer and browns the surface, giving the golden crust and long, stretchy pull that make queso fundido so appealing.

Notes and substitutions

Choose a firm melting cheese such as Monterey Jack or asadero. These cheeses melt smoothly without separating, and they stretch well when torn.

Grate the cheese yourself from a block; pre-shredded packages often contain anti-caking starches that keep them from melting as evenly. Sharp cheddar can be blended in for more flavor, but keep most of the cheese a mild melting type so the texture stays creamy.

A 10-inch cast iron skillet is the best equipment here because it goes from stove to oven without changing pans. If you do not have cast iron, use an oven-safe skillet of the same size. Use a box grater for the cheese and a sharp chef's knife for the vegetables so the cubes stay uniform. A wooden spoon is useful for stirring the vegetables into the sauce without scraping the skillet surface.

• sweet potato: butternut squash cut into the same small cubes, baked a few minutes longer until tender
• firm melting cheese: a blend of Monterey Jack and sharp cheddar, both grated, for a sharper flavor
• green chili pepper: a pickled jalapeño, drained and chopped, for a tangier heat
