Prep and Cook Time

• Preparation: 20 minutes
• Roasting: 30 minutes
• Baking: 25 minutes
• Total Time: 1 hour 15 minutes

Yield

Serves 6 generous portions

Difficulty Level

Medium – approachable for home cooks with some roasting and layering experience

Ingredients

• 3 cups butternut squash, peeled and cubed
• 2 cups yellow summer squash, sliced into ½-inch rounds
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 cup sharp white cheddar cheese, shredded
• 1 cup heavy cream
• ½ cup whole milk
• 2 tablespoons unsalted butter
• ¼ cup fresh parsley, chopped
• 1 teaspoon dried thyme
• 1 teaspoon smoked paprika
• ½ teaspoon ground nutmeg
• Salt and freshly ground black pepper, to taste
• ½ cup panko breadcrumbs
• 2 tablespoons grated Parmesan cheese

Instructions

1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare the squash: Toss butternut and yellow squash cubes/rounds with 1 tablespoon of butter, salt, pepper, smoked paprika, and half the thyme. Spread evenly on the baking sheet.
3. Roast the squash for 25-30 minutes until tender and lightly caramelized, flipping halfway through for even browning. The roasting stage deepens the natural sugars, ensuring peak flavor.
4. Meanwhile, sauté the aromatics: In a skillet, melt the remaining butter over medium heat. Add diced onions and cook until translucent (5 minutes). Stir in garlic and sauté another 30 seconds until fragrant-don’t let it burn!
5. Make the creamy base: Lower heat to medium-low and pour in heavy cream and whole milk, stirring to combine. Add nutmeg and the remaining thyme. Simmer gently for 3 minutes, then remove from heat.
6. Assemble the casserole: In a mixing bowl, combine roasted squash, sautéed onions and garlic, and creamy base. Fold in shredded cheddar and chopped parsley. Adjust salt and pepper according to your taste.
7. Transfer the mixture into a greased 9×13-inch baking dish, spreading evenly.
8. Create the topping: Mix panko breadcrumbs with grated Parmesan cheese. Sprinkle generously over the casserole for a delightful crunch.
9. Bake uncovered at 375°F (190°C) for 20-25 minutes, until the top is golden brown and bubbling at the edges.
10. Rest briefly on a cooling rack for 5 minutes before serving. This helps the layers set and makes slicing cleaner.

Chef’s Notes: Tips for Success

• For ultimate tenderness, don’t rush the roasting process. Proper caramelization enhances flavor complexity and texture contrast in your casserole.
• Fresh herbs make a difference. If you lack fresh parsley or thyme, dry herbs can be substituted but use sparingly to avoid overpowering the dish.
• Try swapping cheddar for Gruyère or fontina for a creamier, nuttier flavor profile.
• A make-ahead delight: Assemble the casserole a day in advance, cover tightly with foil, and refrigerate. Add the breadcrumb topping just before baking.
• For a veggie twist, you can include thinly sliced zucchini or delicate carrot ribbons layered between the squash.

Serving Suggestions

This roasted squash casserole shines when paired with a crisp autumn salad-a mix of arugula, toasted pecans, and dried cranberries tossed in a light citrus vinaigrette brings brightness and contrast. Garnish each serving with an extra sprinkle of fresh parsley and a few microgreens for a pop of color. A warm, crusty whole-grain bread alongside helps soak up any luscious juices, making every bite memorable.
