Butternut Squash Casserole with Crunchy Topping (Fall Potluck Winner)

When I walk into a potluck and someone mentions “that amazing squash casserole,” I know exactly which recipe they mean. This **butternut squash casserole with crunchy topping** blends creamy mashed squash, warm spices, and a buttery, herb‑breadcrumb crust you’ll want to dig into first. Below you’ll find why this recipe became a staple, full ingredients, step‑by‑step instructions, tips & variations and FAQs.

Why This Casserole Steals the Show

A Comforting Crowd-Pleaser

Some dishes look humble but taste like pure comfort—and this casserole is one of them. The very first time I brought it to a Thanksgiving gathering, people asked for the recipe before it was even half eaten. That crunchy topping? Always the first to vanish. It’s become my go-to for gatherings and family dinners alike.

I love pairing it with lighter sides—like a crisp green salad or roasted veggies—so the casserole remains the star without overwhelming the meal. It sits well alongside dishes like roasted butternut squash soup on a cool evening.

Texture & Flavor Balance

The magic lies in the contrast: soft, buttery squash base with hints of warm spice, topped with a crisp, golden crust. Butter, herbs, and breadcrumbs elevate it from “just another casserole” to a showstopper. Each bite offers creaminess and crunch.

One tip: let it rest a few minutes after baking. The topping continues to crisp while the filling sets, making servings cleaner and more satisfying.

Ingredients

Gather these elements before you start:

Ingredient	Quantity
2 pounds butternut squash, peeled, seeded, cubed	2 lbs
1/2 cup heavy cream (or milk or non‑dairy milk)	½ cup
2 tablespoons butter (or plant‑based)	2 tbsp
1 large egg (or flax egg for vegan)	1
1 teaspoon ground nutmeg	1 tsp
1/2 teaspoon ground cinnamon	½ tsp
Salt & black pepper, to taste	—
1 cup breadcrumbs (panko or regular)	1 cup
2 tablespoons melted butter or oil (for topping)	2 tbsp
Fresh herbs (parsley or thyme), finely chopped (optional garnish)	To garnish

Step‑by‑Step Instructions

Here’s how you bring it all together:

1. Preheat oven to 375°F (190°C). Grease or line a casserole dish.

2. Steam or boil the butternut squash cubes until tender (about 10–12 minutes). Drain well.

3. In a bowl, mash the cooked squash. Add the cream, butter, egg (or flax egg), nutmeg, cinnamon, salt, and pepper. Mix until smooth and creamy.

4. Spread the squash mixture into the prepared casserole dish evenly.

5. In a separate bowl, combine breadcrumbs with melted butter (or oil) and chopped herbs. Toss so crumbs are evenly coated.

6. Sprinkle the breadcrumb mixture evenly over the squash base.

7. Bake for 25–30 minutes until the topping turns golden and crispy and the edges bubble slightly.

8. Let rest for 5–10 minutes before serving to let the casserole set for cleaner scoops.

Tips, Variations & Serving Ideas

Make It Vegan or Lighter

Use non‑dairy milk and vegan butter. Replace the egg with a flax egg (1 tbsp flax meal + 3 tbsp water). Use whole grain or gluten-free breadcrumbs if needed.

To lighten it, use milk instead of cream, or reduce the butter in the topping and toss it with a bit of olive oil.

Flavor Twists & Additions

Stir in grated cheddar or Gruyère for a cheesy twist under the topping. Add cooked sausage or sautéed mushrooms for extra heft. A sprinkle of toasted pecans or walnuts over the topping gives crunch and depth.

Serve with a crisp green salad or steamed greens to balance richness. The leftovers reheat nicely—just warm in oven at 350°F for 10 minutes.

Frequently Asked Questions

Can I prep parts ahead?

Yes. Cook and mash the squash in advance, store in the fridge. Mix topping separately. Assemble and bake just before serving.

How do I avoid soggy topping?

Ensure drizzle in the melted butter or oil on breadcrumbs is enough to coat without soaking. Bake until topping is golden and set. Let rest to firm up.

Is it gluten-free?

Use gluten-free breadcrumbs and ensure other ingredients are gluten-free. The rest is naturally gluten-free.

Can I double this recipe?

Yes. Use a larger dish and adjust baking time slightly (add 5–10 minutes) until topping is golden and center is hot.
