Ingredients for cozy fall squash casserole crowd
- 2 lb butternut squash, peeled and cubed
- 3 tbsp butter
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 cup vegetable broth
- ½ cup heavy cream
- ½ cup parmesan cheese, grated
- ¼ cup breadcrumbs
- 2 eggs
- ½ cup gruyere cheese, shredded
- 1 tsp fresh sage
- ½ tsp thyme
- 2 tbsp olive oil
- Salt and pepper to taste
For ingredient swaps, you can substitute acorn squash or kabocha squash if butternut isn’t available. The flavor profile remains excellent with either option, though cooking time may vary slightly depending on squash density. Gruyere can be replaced with aged cheddar or fontina if needed, though gruyere’s nutty complexity is worth seeking out.
Make sure to use fresh herbs rather than dried when possible for the most vibrant fall casserole flavor. Dried herbs work in a pinch—use one-third the fresh amount. Purchase pre-cubed butternut squash from the produce section to cut prep time by ten minutes.
Step-by-step fall squash casserole instructions
1. Preheat your oven to 375°F and lightly oil a 9×13-inch baking dish. Cut butternut squash into 1-inch cubes, removing seeds and skin. Cook cubed squash in boiling salted water for 8-10 minutes until fork-tender, then drain thoroughly in a colander.
2. While squash cooks, melt butter with olive oil in a large skillet over medium heat. Add diced onion and sauté for 4 minutes until softened, then add minced garlic and cook 1 minute more until fragrant.
3. Pour vegetable broth into the skillet and bring to a simmer. Let it reduce by half, approximately 5-7 minutes, concentrating the savory flavors throughout.
4. Transfer cooked squash to a large mixing bowl and mash gently, leaving some small chunks for texture. Stir in the broth mixture, heavy cream, parmesan, eggs, sage, and thyme until well combined. Season with salt and pepper to taste.
5. Prepare this cozy fall squash casserole crowd recipe by pouring the mixture into your prepared baking dish. Combine breadcrumbs with 1 tablespoon melted butter and sprinkle evenly across the top, then scatter gruyere cheese over the breadcrumbs.
6. Bake for 25-30 minutes until the top turns golden brown and the edges bubble gently. A knife inserted in the center should reveal a set but slightly creamy interior. Let rest 5 minutes before serving.
