The Squash & Zucchini Casserole That Became a Family Favorite

This casserole came into our lives during a summer when the garden had far too much confidence in my ability to keep up with it.

Between squash and zucchini growing faster than I could pick them, I needed a recipe that was simple, comforting, and forgiving. This one quickly became the answer. We made it once, then again, and before long, it earned a permanent place in our rotation, requested year after year, long after that particular garden season passed.

Originally inspired by a Taste of Home recipe, this version has been gently adapted in our kitchen over time. A sweet Vidalia onion instead of shallots, a pinch of crushed red pepper for just a little warmth, small changes that made it feel like ours.

Yellow Squash & Zucchini Casserole

Adapted from Taste of Home

Ingredients

• 2 tablespoons butter

• 2 medium zucchini, sliced ¼-inch thick

• 2 medium yellow summer squash, sliced ¼-inch thick

• 1 small Vidalia onion, thinly sliced

• ½ teaspoon sea salt

• ¼ teaspoon coarsely ground black pepper

• Pinch of crushed red pepper (more or less to taste)

• 4 garlic cloves, minced

• ½ cup heavy whipping cream

• 1 cup panko bread crumbs, divided

• ½ cup grated Parmesan cheese, divided

Directions

Preheat the oven to 450°.

In a large skillet, melt the butter over medium heat. Add the zucchini, yellow squash, and onion. Season with salt, black pepper, and crushed red pepper. Cook, stirring occasionally, until the vegetables are just tender, about 4–6 minutes. Add the garlic and cook one minute more.

Pour in the cream and cook until slightly thickened, 3–5 minutes. Remove from heat and stir in ½ cup of the breadcrumbs and ¼ cup of the Parmesan. Spoon the mixture into a greased 11×7-inch baking dish or 2-quart casserole. Sprinkle with the remaining breadcrumbs and cheese.

Bake until golden and bubbling, about 8–10 minutes. Let it rest briefly before serving.

This is one of those dishes that works just as well alongside a weeknight dinner as it does on a fuller table. Simple, comforting, and always welcome.
