Pro Tips for Making This Zucchini or Yellow Squash Casserole
Here are some of my tried-and-true tips to help you create the perfect Zucchini or Yellow Squash Casserole every time:
Don’t skip the sauté: Sautéing the zucchini, yellow squash, onion, and garlic beforehand is so important. It helps to release their flavors and soften them, so they’re tender in the final dish.
Grate your own cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly. Grating your own cheese ensures a perfectly creamy sauce.
My Secret Trick: To prevent the cracker topping from burning, I always tent the casserole with foil during the last 10 minutes of baking. This ensures the cheese is bubbly and the topping is perfectly golden, never burnt.
Fun Variations for Zucchini or Yellow Squash Casserole
Want to add a little twist to your Zucchini or Yellow Squash Casserole? Here are a few easy substitutions and variations that I love:

Add protein: Stir in some cooked diced ham or crumbled bacon for a heartier dish.
Use different cheeses: Experiment with different cheeses like Gruyere, Monterey Jack, or even a bit of goat cheese for a unique flavor profile.
Go gluten-free: Substitute the all-purpose flour with a gluten-free blend and use gluten-free crackers for the topping.
