Preheat the oven to 400°F (200°C) and prepare a baking sheet lined with parchment paper or greased lightly with olive oil.

Wash and slice the yellow squash into uniform 1/4-inch rounds and arrange them in a single layer on the baking sheet.

Drizzle olive oil over the squash, then sprinkle with oregano, basil, salt, and pepper.

In a bowl, mix together the cheddar and parmesan cheese until well combined.

Sprinkle the cheese mixture over the squash rounds and then add breadcrumbs, pressing them gently into the cheese.

Bake in the oven for 15 to 20 minutes, until the squash is tender and the cheese is bubbly and golden brown.

Remove from the oven and let cool for a minute before serving.
