Step 1

Preheat the oven to 375 degrees F.

Step 2

In a large oven-safe saute pan, heat 1 Tablespoon of butter and 2 Tablespoons of olive oil over medium heat. Add onions and cook for 2-3 minutes or until they begin to soften.

Step 3

Add zucchini, spreading in a single layer as much as possible. Season with oregano, salt, and pepper. Cook for about 5 minutes, or until just begins to soften, tossing couple times. They should still be fairly firm after 5 minutes.

Step 4

While the zucchini is cooking, cut the corn from the cob and place into a bowl. To the same bowl, transfer the cooked zucchini mixture.

Step 5

Increase the heat to medium-high. Add the remaining 2 Tablespoons of butter and 1 Tablespoon of olive oil to the pan. Season the chicken on both sides with salt and pepper. When the oil is hot, add chicken to the pan in a single layer and sear for 1-2 minutes per side. You want a lightly golden outside. The inside will still be raw.

Step 6

Remove the pan from the heat and top the chicken with zucchini corn mixture. Sprinkle with Parmesan cheese and bake, uncovered, for 15-18 minutes or until the chicken is cooked through and the zucchini is tender. Garnish with fresh basil and additional Parmesan cheese, if desired.
