Ingredients in a Squash Casserole
While some recipes contain additives and fillers like eggs and bread crumbs, this squash casserole recipe focusses on the squash itself.
Onion: Onion adds flavor to this dish; stir in a little bit of garlic if you’d like. Squash: Fresh yellow squash and zucchini are the stars here. Choose ones that are firm and bright in color for the best taste and texture. Topping: butter, seasoned bread crumbs, and cheddar cheese add a perfect crisp topping to this recipe. Swap the bread crumbs for Panko breadcrumbs or crushed Ritz crackers or saltines to make a buttery cracker topping. Other cheeses such as Gruyere or Monterey jack can be used in this recipe. Optional Add-Ins: red or green bell peppers, cheeses, garlic, tomatoes
Make It Your Way
This yellow & zucchini squash casserole can be made to your preference as far as texture. For a softer casserole, slice the zucchini a bit thinner, and when sauteeing in the frying pan, cook it a little bit longer so it’s tender-crisp but a bit on the softer side. For tender-crisp squash, keep the zucchini at 1/4″ thickness. Be sure you don’t overcook it.
How to Make Squash Casserole
Place squash and onions upright (standing on the edge) in a casserole dish. Just tucke the onions into the squash mixture.
Can It Be Reheated?
Zucchini squash casserole tastes best when served fresh from the oven but of course it can be reheated. Store leftover squash casserole tightly covered in the refrigerator for up to four days. The breadcrumbs won’t be as crisp but the squash itself will still taste delicious! To reheat bake until hot (or you can reheat in the microwave). Then turn on the broiler element and put the heated casserole below the broiler for a few minutes of cooking to re-crisp the bread crumbs. Better yet, make a fresh batch of crumbs and top the leftovers with these.
Serving Suggestions
Zucchini squash casserole pairs well with just about any meaty main dish. Serve it with roasted or grilled chicken, barbecued ribs or hamburgers. It also goes great with Salisbury steak or pork chops with mushroom gravy.
