Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 4 cups sliced zucchini (about 2 medium)
  • 3 cups sliced yellow squash (about 2 medium)
  • 1 cup shredded cheddar cheese
  • 1/2 cup sour cream
  • 1/4 cup mayonnaise

  3. Add garlic and cook for 1 minute more until fragrant.
  4. Add zucchini and yellow squash to the skillet. Cook, stirring occasionally, until the squash is tender-crisp, about 8-10 minutes.

  6. Stir the cheese mixture into the skillet with the squash. Season with salt and pepper.
  7. Transfer the mixture to a lightly greased 8×8 inch baking dish.
  8. Sprinkle breadcrumbs evenly over the top.
  9. Bake for 20-25 minutes, or until the topping is golden brown and the casserole is bubbly.

Notes

  • For a creamier casserole, you can add an extra tablespoon of sour cream or mayonnaise.
  • Feel free to add other vegetables like bell peppers or corn.
  • You can substitute Gruyere cheese for cheddar for a different flavor.
