Cookware
baking dish · chef's knife · colander · cutting board · measuring cups · measuring spoons · nonstick skillet · oven mitts · spatula · stirring spoon
Directions
- Preheat the oven to 425°F and oil a small baking dish lightly.
- Warm a skillet over medium-high heat to start sautéing the vegetables.
- Add a thin layer of oil to the skillet, then the mushrooms with a pinch of salt and pepper; cook until softened, about 3–4 minutes.
- Meanwhile, cut the polenta into crosswise rounds about 1/2 inch thick.
- Wash and dry the spinach before you’re ready to use it.
- When the mushrooms start to soften, add the spinach in handfuls, letting each batch wilt before adding the next; stir in the pesto and remove from heat.
- Arrange the polenta slices in an overlapping layer along the bottom of the baking dish, top with the sautéed vegetables and pesto, and sprinkle with the cheese.
- Bake in the oven until the cheese is bubbly and golden, 8–10 minutes; remove and let stand briefly before serving.
Two tips
- Leftovers keep well in the fridge for 2–3 days; reheat in a hot oven or microwave until warmed through.
- If you like a different finish, swap in another Italian cheese blend you have on hand for a different melt and flavor.
