Prep Work
Before we dive into assembling our Pattypan Squash Casserole, it’s essential to complete a few simple prep tasks. This groundwork ensures our casserole bakes evenly and achieves that perfect creamy texture with a crisp topping.
Preparing the Pattypan Squash
First, wash the 2 pounds of fresh pattypan squash thoroughly under cold running water to remove any dirt. Pat them dry with a clean towel. Next, trim off both ends of each squash to remove the stem and blossom tips. Using a sharp chef’s knife, cut the squash into uniform ½-inch thick slices. This thickness ensures even cooking and a tender bite without becoming mushy.
As a visual and flavor note, the charming scalloped edges of the pattypan should remain intact for presentation. Place the sliced squash into a large mixing bowl ready for seasoning and combining with the other casserole ingredients.
Preheating the Oven
To achieve optimal baking results, preheat your oven to 375°F (190°C). This temperature strikes the perfect balance, allowing the squash to cook gently in the creamy sauce while creating a golden, bubbly crust on top.
Place the oven rack in the center position for even heat distribution. Once preheated, we can move forward with layering and baking our casserole with confidence.
| Task | Details |
|---|---|
| Oven Temperature | 375°F (190°C) |
| Rack Position | Center |
| Preheat Duration | About 10-15 minutes |
Preparing Other Ingredients
While the oven preheats and the squash rests, let’s prepare our other casserole components:
- Garlic: Mince 2 cloves of fresh garlic finely to infuse the casserole with rich aroma and subtle heat.
- Cheese: Grate 1 cup sharp cheddar and ½ cup Parmesan cheese. Freshly grated cheese melts better and offers more flavor than pre-shredded options.
- Heavy Cream & Dijon Mustard: Measure out 1 cup heavy cream and 1 teaspoon Dijon mustard to create a luscious, tangy sauce that complements the mild sweetness of the squash.
- Panko Breadcrumbs: Have ½ cup panko breadcrumbs ready to mix with 2 tablespoons melted butter for a crunchy topping.
- Seasonings: Keep salt, black pepper, and ¼ teaspoon nutmeg on hand to season the casserole perfectly.
By completing these steps, we set ourselves up for smooth assembly and a flavorful Pattypan Squash Casserole that will impress with its creamy texture and crisp golden crust.
Directions
Follow these detailed steps to create a creamy and flavorful Pattypan Squash Casserole that’s sure to impress.
Making the Sauce
- Melt 3 tablespoons of butter in a medium saucepan over medium heat.
- Add 2 cloves of minced garlic and sauté for 1-2 minutes until fragrant but not browned.
