Slice the prepared polenta tube into ½-inch thick rounds. Alternatively, if using homemade polenta, spread cooked polenta into a shallow baking dish, chill until firm, then slice into squares, rounds, or sticks.
02 -
Warm the olive oil in a large skillet over medium-high heat until shimmering. Test by placing a small piece of polenta in the skillet; it should sizzle immediately.
03 -
Arrange polenta slices in a single layer in the skillet without overcrowding. Fry for 3 to 4 minutes per side until golden brown and crisp.
04 -
Transfer the fried polenta onto a paper towel-lined plate to absorb excess oil. Immediately season with salt and black pepper to taste.
05 -
Heat the marinara sauce in a small saucepan over medium heat until hot throughout.
06 -
Serve the crispy polenta warm alongside the marinara sauce for dipping, or spoon sauce over the polenta. Optionally garnish with grated Parmesan, fresh basil, and a pinch of red pepper flakes.
