Bob Luby opened his first restaurant in 1947 in San Antonio. Today, there are over 30 Luby’s locations serving classic comfort foods such as meatloaf, mac and cheese, fried fish, pork chops, and mashed potatoes.

What to Serve with Zucchini and Summer Squash Casserole

If you want a home-cooked meal that reminds you of Luby’s, you can serve this casserole with hearty dishes such as Luby’s Italian chicken breast, pork chops, bacon cheese steak, or Luby’s Cafeteria baked white fish.

The delicious squash and vegetable casserole is adaptable and tastes terrific with any meat you pair it with. You can also make some dinner rolls or garlic bread to accompany it.

How to Store Leftover Summer Squash Casserole

You can keep any leftovers in the baking dish you cooked it in, provided that you wrap it tightly with foil. You can also transfer it to a container with a fitting lid.

It stays fresh in the refrigerator for up to four days. I don’t recommend freezing it since the squash will turn watery and mushy when thawed.

What is the Best Way to Reheat Squash Casserole?

You can reheat the casserole in the microwave quickly. Cover it with a paper towel when doing so.

You can also pop it back in a 350°F oven. Make sure it is fully heated before enjoying – check the center’s temperature before removing it!
