For the Topping:

7. Combine the breadcrumbs, grated Parmesan cheese, and chopped fresh basil in a bowl. This mixture will form a crunchy, flavorful topping that contrasts beautifully with the soft vegetables.

Absolutely! For the best flavor and texture, I recommend using a mix of yellow squash and zucchini. Choose firm, unblemished specimens that are vibrant in color. Avoid any squash with dark spots or soft areas, as they may be past their prime.

How should I store leftovers of the casserole?
You can store any leftovers in an airtight container in the fridge for up to 3 days. This ensures that the casserole retains its delicious flavors and doesn’t dry out. When you’re ready to enjoy it again, just reheat in the oven for that freshly-baked taste!

Can I freeze Summer Squash Casserole?
Yes, you can! To freeze, let the casserole cool completely. Then, wrap it tightly in plastic wrap and aluminum foil. It can be stored in the freezer for up to 3 months.

What if my casserole is too watery after baking?
If you find your casserole is too watery, it might be due to excess moisture from the squash or tomatoes. To troubleshoot, you can pre-sauté your squash to release excess water before layering them into the casserole. Additionally, you can bake it uncovered for the last 10 minutes of cooking to allow steam to escape and the sauce to thicken.

Is this casserole suitable for dietary restrictions?
Yes! This Summer Squash Casserole with Tomatoes and Mozzarella is easily adjustable. For a vegetarian version, simply omit the sausage and replace it with crumbled meat substitutes. If you’re looking for a vegan option, use plant-based cheese and leave out the dairy altogether.

Great question! Consider using fresh herbs like basil and oregano instead of dried ones for a more vibrant flavor.
