Key Ingredients & Substitutions
Zucchini and Yellow Squash: These veggies are star players in this casserole! You can mix them up with other summer squash like pattypan or even use eggplant if you prefer something different.
Cheese: Cheddar and mozzarella create a creamy flavor, but feel free to swap in your favorites! Monterey Jack or Gouda can work too. For a dairy-free option, try vegan cheese alternatives that melt well.
Sour Cream or Greek Yogurt: Both add creaminess and tang. If you want a lighter version, consider low-fat yogurt or even cashew cream if you’re looking for a dairy-free substitute.
Breadcrumbs: These give a lovely crunch, but you can leave them out if you’re watching carbs. Alternatively, panko breadcrumbs or crushed crackers can add a nice texture.
Why is Sautéing the Onions and Garlic Important?
Sautéing onions and garlic before adding them to the casserole enhances their flavors. It softens them, bringing out their natural sweetness. Here’s how to do it right:
- Heat your skillet to medium heat.
- Pour in olive oil or butter, then add chopped onions and minced garlic.
- Cook for about 3-4 minutes until they are soft and fragrant, stirring occasionally.
- This will prevent them from being raw in your casserole, making every bite delicious!
How Can I Ensure My Casserole Sets Perfectly?
For a well-set casserole, it’s essential to mix your ingredients evenly and bake thoroughly. Here are some tips:
- Make sure the egg and sour cream mixture is fully incorporated so it binds everything together.
- Don’t skip the baking time; undercooking can lead to a watery casserole.
- Letting it cool for a few minutes after baking allows it to firm up before serving.

Step-by-Step Instructions:
1. Prepare the Oven & Dish:
Start by preheating your oven to 350°F (175°C). While the oven heats, lightly grease a 9×13 inch baking dish with cooking spray or a bit of butter to prevent sticking.
2. Sauté Onions and Garlic:
In a large skillet, heat the olive oil or butter over medium heat. Add the chopped onions and minced garlic, and sauté for about 3-4 minutes, until the onions are soft and fragrant. This step adds wonderful flavor to your casserole!
3. Mix the Vegetables and Cheese:
In a big mixing bowl, combine the sliced zucchini and yellow squash with the sautéed onions and garlic. Then, add the shredded cheddar, mozzarella, and half of the Parmesan cheese to the bowl. Stir gently to mix everything together.
4. Combine the Creamy Mixture:
In a small bowl, whisk together the sour cream (or Greek yogurt), eggs, dried oregano, and a bit of salt and pepper. This will add creaminess and help bind your casserole.
5. Bring It All Together:
Pour the creamy mixture into the bowl with the vegetables and cheeses. Gently stir until everything is evenly combined—don’t be too rough to keep the veggies intact!
6. Transfer and Prepare for Baking:
Next, transfer the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining Parmesan cheese and breadcrumbs on top for a delightful crunchy layer.
7. Bake to Perfection:
Place the dish in the oven and bake uncovered for 35-40 minutes. Keep an eye on it, and look for a golden brown top with bubbly edges as it cooks—this means it’s done!
8. Cool & Serve:
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This helps it set a bit more. Finally, if you’d like, garnish with fresh parsley or chives for a pop of color before serving.
