Ingredients

  • 3 lbs green zucchini (approximately 6 medium-sized zucchinis)
  • 1 1/2 tsp salt, divided (1 tsp for sprinkling and 1/2 tsp for the casserole)
  • 2 cups cooked white rice
  • 1 cup sour cream (divided into 2/3 and 1/3)
  • 1/2 tsp baking powder
  • 4 large eggs
  • 1/2 tsp Mrs. Dash seasoning (or any preferred salt-free seasoning)
  • 8 oz Colby Jack cheese (about 3 cups shredded) or use Mexican cheese
  • 1/2 cup chopped chives, plus extra for garnish

Instructions

  1. Preheat the oven to 400°F and butter a 9×13-inch casserole dish.
  2. Grate the zucchini using the large holes of a grater or the grating attachment on a food processor. Place the grated zucchini in a colander over the sink, sprinkle with 1 tsp of salt, and let it sit for 10 minutes. Stir the zucchini a couple of times during this time. Afterward, squeeze out excess moisture using your hands and transfer the drained zucchini to a large mixing bowl.
  3. In a separate bowl, mix 2/3 cup of sour cream with 1/2 tsp of baking powder and set aside for 8-10 minutes while the zucchini drains.
  4. To the bowl with the drained zucchini, add the eggs and the sour cream mixture. Stir until well combined.
  5. Stir in the cooked rice, 2 cups of shredded cheese, 1/2 cup of chopped chives, 1/2 tsp of salt, and the Mrs. Dash seasoning.
  6. Pour the mixture into the buttered casserole dish and spread 1/3 cup of sour cream evenly over the top. Sprinkle the remaining 1 cup of shredded cheese over the casserole.
  7. Bake uncovered for 40 minutes at 400°F until the casserole is set and golden on top. Let stand for 10 minutes before serving.

Tips

  • Drain Zucchini Well: Squeezing out the excess moisture from the zucchini is crucial to prevent the casserole from becoming watery.

  • Cheese: Feel free to use a combination of cheeses for added flavor, such as mozzarella or cheddar.
  • Make Ahead: This casserole can be prepared ahead of time. Assemble it and store it in the fridge for up to a day before baking.

Variations and Substitutions

  • Zucchini Alternatives: If zucchini is not available, you can substitute it with yellow squash.
  • Rice: Use brown rice for a heartier option or try quinoa for a different flavor.
  • Dairy-Free Option: For a dairy-free version, substitute the sour cream with a dairy-free yogurt and use a dairy-free cheese.
  • Egg-Free: To make this casserole egg-free, you can try using a flax or chia egg substitute.

FAQs

  • Can I use frozen zucchini?
    It’s better to use fresh zucchini for this casserole since frozen zucchini contains more moisture, which may affect the texture.

    This casserole makes a great side dish for grilled meats or roasted chicken. It can also be served as a vegetarian main course with a fresh salad.
