Squash Casserole from 'Mastering the Art of Southern Cooking'

Kate Williams

As Nathalie Dupree explains in her and Cynthia Graubart's new cookbook, Mastering the Art of Southern Cooking, squash casserole is an enduring favorite at Southern potlucks. I know that I ate plenty of the stuff growing up, but it was mostly because the flavor of the squash was covered up by ungodly amounts of cheese and butter. These days, I prefer actually tasting my vegetables. Luckily, Dupree's version contains enough squash, onion, and peppers to taste more of summer produce than bulk cheese.

Why I picked this recipe: This dish is a potluck classic for a reason: buttery squash meets cheesy custard meets butter and pecans. What's not to love?

What worked: Dupree's version is certainly the most colorful squash casserole I've encountered, and these extra vegetables serve double duty as a lightener amongst all that butter and cheese. The nutty pecan and breadcrumb topping offered excellent contrast to the tender squash mixture.

What didn't: Next time, I'd cook the casserole for a shorter time, as the eggs were a bit overdone went I pulled it at 45 minutes. Start checking after 30 and you should be good to go.

Suggested tweaks: I opted to forgo boiling the squash, instead sautéing it until mashable. This saved an extra pot and added a bit more flavor. Be sure to drain the squash well before mashing it and adding it to the rest of the ingredients—vegetable water is the enemy of a good casserole.

  1. Preheat oven to 350 degrees. Butter a large casserole dish and set aside.

  2. Melt 1/4 cup of the butter in a large skillet and sauté the onions and peppers until soft. Add the garlic and cook 1 minute then set aside.
