What is Summer Squash Casserole?

Unlike many squash casseroles that are bathed in butter, cream, cheddar cheese, and mayonnaise, which often is among the ingredients of classic southern summer squash casseroles served at diners and church suppers in the south; this lower-calorie rendition focuses on a creamy béchamel comprised of butter and flour that has been cooked together (a mixture that’s also known as a roux) and milk, with just a bit of seasoning.

The sauce is then studded with fresh sweet corn creating a silky, creamy base for perfectly cooking the layers of tender squash as it clings to the crackers in the way a good sauce should – and it’s the roux we must thank for that.

Other than making the sauce, there’s not much more to prepare for the dish other than slicing the summer squash, crushing the crackers, and then layering it all together. To give the casserole maximum visual appeal, I especially like using a combination of yellow summer squash and green zucchini for the variety of beautiful colors in the finished dish. Because everyone knows we eat with our eyes first.

How to Make the Béchamel (White Sauce)

To make the roux for the béchamel, you heat the fat (in this case, the butter) and whisk in roughly equal parts of flour, simmering it just long enough to get the raw flavor out of the flour but not so long as the flour changes to a blonde or darker stage resulting in a nutty flavor. But that’s not what we want here.

After the roux is adequately cooked, the next step is to whisk in the milk. At this point, you may notice that this sauce is fat (butter), flour, and more fat (milk) – and that’s why it’s so darned good. But it’s the milk that turns the roux into the sauce. The trick is not to dump the milk into the roux at once. To create a velvety smooth consistency (a necessity in making béchamel), gradually whisk in the milk, so it doesn’t become clumpy or too thick. As a note, I’d like to mention that different recipes using béchamel will call for different amounts of milk and varied cooking times to produce a consistency from thick and almost spreadable to a medium thickness and nearly pourable as for this recipe.

Once you reach a medium thickness, it’s time to season the béchamel with the chicken broth base, salt, and white pepper; then stir in the sweet corn kernels, and that’s it!

Now, all you need to do is assemble the casserole.

Make Southern Summer Squash Casserole in Advance

Assemble the Casserole in advance. Once everything is layered into your oven-safe baking dish, cover it tightly with plastic wrap or aluminum foil and refrigerate for up to 24 hours until ready to bake.

Before baking, let the casserole sit on the counter to warm to room temperature for at least 30 minutes before putting it in the oven. Please note that if the contents are still cold, you may need to extend the baking time by a few minutes until it becomes bubbly around the edges and the top is golden brown.

Casserole Variations:

  • Add a pinch or two of fresh herbs such as basil, parsley, thyme, or oregano. Even freshly chopped chives would be a great addition for adding another flavor layer!
  • Instead of saltines, substitute gluten-free dry stuffing mix with melted butter for a flavorful topping (or use buttery club crackers or Ritz crackers – but only if you don’t need to be gluten-free). Other good options you might want to try might be gluten-free corn flakes or panko-style breadcrumbs.
  • Use zucchini instead of summer squash, or try a combination of the two.
  • Cooking for only a few? Adjust the recipe by changing the number of portions.
  • We make it easy to adjust the servings size. CLICK HERE to learn how.

The béchamel makes all the difference in this casserole we were first introduced to at a summer potluck with friends outside Nashville. With one bite, our family (kids included) immediately fell in love with the creamy, tasty combination of ingredients that deliciously meld together when baked. Loaded with tender summer squash, the béchamel sauce with creamy corn, crackers, and a buttery taste, it’s an authentic Southern comfort food knock-it-out-of-the-ballpark recipe that will win a homerun with everyone at your table.

Especially for the simplicity of making it!
