Tips for the Perfect Yellow Squash Casserole ✅
- Drain Excess Moisture: If your squash is very watery, consider sprinkling it with a pinch of salt and letting it sit for 10 minutes before sautéing. This helps prevent a soggy casserole.
- Cheese Variations: Try adding Monterey Jack or mozzarella for a milder, stretchy texture, or mix in a little Parmesan for a nutty flavor.
- Breadcrumb Alternatives: If you want a gluten-free option, crushed cornflakes or almond meal work beautifully as a topping.
- Make Ahead: You can prepare the casserole up to the baking step a day in advance. Cover tightly and refrigerate, then bake when ready to serve.
