Slice the mush: Once fully chilled and firm, run a knife around the edges of the pan and gently turn the mush out onto a cutting board. Slice into 1/2-inch to 3/4-inch thick pieces, depending on how sturdy you want them.
Heat the skillet: In a large nonstick or well-seasoned cast iron skillet, heat 2–3 tablespoons of oil or butter over medium heat until hot and shimmering.
Fry the slices: Carefully add the cornmeal mush slices in a single layer, without overcrowding the pan. Fry for 4–5 minutes per side, or until the outsides are golden brown and crisp. Adjust the heat as needed so they brown but don’t burn.
Drain and serve: Transfer the fried slices to a plate lined with a paper towel to drain any excess oil. Serve warm with your choice of toppings—maple syrup or jam for sweet, or a sprinkle of salt, pepper, and hot sauce for savory.
For a cheesy twist, stir 1/2 to 1 cup of shredded cheddar or parmesan into the hot cornmeal mush before chilling; this version is great served with eggs or a simple salad. If you prefer whole grains, swap part of the water for milk to make the mush creamier, or use a medium-grind cornmeal for more texture. For a slightly sweeter breakfast-style mush, add 1–2 tablespoons of sugar or honey to the cooking liquid and top the fried slices with fruit and yogurt. You can also season the base with garlic powder, black pepper, or a pinch of smoked paprika if you know you’ll serve it as a savory side. To save time on busy mornings, make the mush the night before and keep it chilled in the pan for up to 3–4 days; just slice and fry what you need. Leftover fried slices reheat well in a dry skillet or toaster oven, so consider doubling the batch if you want easy, ready-to-go sides for the week.
