How to Make Easy Zucchini Orzo Casserole
Prepare the Ingredients
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch (23×33 cm) baking dish with cooking spray or olive oil.
- Cook the orzo. In a large pot of boiling salted water, add 1 cup of orzo and cook until al dente, about 8-10 minutes. Drain and set aside.
- Grate the zucchini. Using a box grater or food processor, shred 2 medium zucchinis. Squeeze out excess moisture using a clean kitchen towel or cheesecloth.
Make the Casserole Mixture
- Sauté the onions and garlic. In a large skillet over medium heat, add 1 tablespoon of olive oil and sauté 1 diced onion and 2 minced garlic cloves for 4-5 minutes, or until soft and fragrant.
- Add the zucchini. Stir in the grated zucchini and cook for an additional 3-4 minutes until softened. Season with salt and pepper to taste.
- Combine ingredients. In a large mixing bowl, combine the cooked orzo, zucchini mixture, 1 cup of ricotta cheese, 1 cup of shredded mozzarella, and ½ cup of grated Parmesan. Mix well until fully combined.
Assemble and Bake
- Transfer the mixture. Pour the orzo mixture into the prepared baking dish, spreading it evenly with a spatula.
- Top with cheese. Sprinkle 1 cup of shredded mozzarella and an additional ¼ cup of Parmesan on top for extra cheesiness.
- Bake the casserole. Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
Serve
- Let cool. Remove the casserole from the oven and allow it to cool for 5-10 minutes before serving. This helps the layers set.
- Garnish and enjoy. Optionally, garnish with fresh basil or parsley and serve warm. Enjoy your delicious Easy Zucchini Orzo Casserole!
Tips for the Best Easy Zucchini Orzo Casserole
- Use fresh zucchini — Opt for firm, fresh zucchini for the best flavor and texture. Avoid overly soft or wrinkled ones as they may contain more moisture.
- Don’t skip the sautéing — Sautéing the zucchini and onions before adding them to the casserole helps to intensify their flavors and reduce excess moisture.
- Check your orzo cooking time — Ensure you cook orzo until al dente as it will continue to absorb liquid while baking, helping maintain the right texture in the final dish.
- Customize with cheese — For added creaminess, consider mixing in a combination of mozzarella and feta cheese. You can also top with grated Parmesan for a golden crust.
- Make it spicy — Add a pinch of red pepper flakes or diced jalapeños for a kick. This elevates the dish and complements the zucchini nicely.
- Prepare ahead of time — Assemble the casserole up to a day in advance and refrigerate. Just bake it when you’re ready to serve for easy meal prep!
Variations to Try
- Mediterranean twist — Incorporate sun-dried tomatoes, Kalamata olives, and a sprinkle of fresh basil for a vibrant Mediterranean flavor.
- Protein boost — Add cooked, shredded chicken or chickpeas to make the casserole heartier and more filling.
- Herb explosion — Experiment with fresh herbs like dill, parsley, or thyme for an aromatic lift.
- Autumn-inspired — Mix in some roasted butternut squash and sage for a seasonal spin that’s perfect for colder months.
