Instructions

1. Spread 1/2 tablespoon of unsalted butter in a 2-quart baking dish measuring 8×11 inches and let it soften at room temperature. Thinly slice the zucchini and yellow squash crosswise using a mandoline or sharp knife. Place them in a colander, sprinkle with 1 1/2 teaspoons of kosher salt, and mix well. Set the colander over a sink or large bowl to allow the squash to drain for 20 minutes. Meanwhile, heat the oven and prepare the béchamel sauce.
2. Position the oven rack in the center and preheat to 350ºF. Mince the garlic cloves. Melt the remaining 4 tablespoons of unsalted butter in a medium saucepan over medium heat. Stir in the garlic and cook until aromatic, about 1 minute. Sprinkle in the flour and whisk continuously until the mixture is lightly golden, about 2 minutes.
3. Gradually add the milk while whisking constantly. Turn the heat to medium-high and bring to a boil, stirring all the while. Lower the heat to keep a simmer and continue whisking until the sauce thickens, approximately 5 to 10 minutes. Take off the heat and mix in the paprika, dry mustard, remaining kosher salt, and black pepper.
4. Once the squash has drained, take a handful at a time, wrap it in a clean kitchen towel or paper towels, and squeeze out as much moisture as possible, then transfer to a bowl. Grate the fontina cheese using the large holes of a box grater.
5. Grease the baking dish with the softened butter. Pour 1/2 cup of the béchamel sauce into the bottom of the dish. Evenly layer half of the squash over the sauce. Drizzle with half of the remaining béchamel (about 1 cup) and sprinkle with half of the fontina cheese. Repeat with the remaining squash, béchamel, and fontina.
6. In a small bowl, combine panko breadcrumbs, grated Parmesan cheese, and olive oil. Season with a pinch of kosher salt and black pepper, and mix thoroughly. Spread this mixture evenly over the top of the casserole.
7. Bake until the casserole is bubbling around the edges, about 40 minutes. Check it at 30 minutes; if the top is browning too fast, cover it loosely with aluminum foil and continue baking. Allow it to cool for 15 minutes before serving.

Notes

Zucchini and Squash Casserole Recipe: Fundamentals

Fundamentals

The zucchini and squash casserole recipe starts with selecting the freshest ingredients. Choose firm, vibrant zucchini and yellow summer squash to ensure the best taste and texture. These vegetables are not only delicious but also packed with nutrients, making them a healthy addition to any meal.

The combination of zucchini and squash provides a delicate balance of flavors. Zucchini brings a mild, slightly sweet taste, while yellow squash adds a hint of nuttiness. Together, they create a harmonious blend that forms the foundation of this dish.

Preparation/setup

Begin by preparing your baking dish. Spread 1/2 tablespoon of unsalted butter in a 2-quart baking dish, allowing it to soften at room temperature. This step ensures that the casserole doesn’t stick and adds a touch of richness to the dish.

Thinly slice the zucchini and yellow squash crosswise using a mandoline or sharp knife. This ensures even cooking and a beautiful presentation. Once sliced, place them in a colander, sprinkle with 1 1/2 teaspoons of kosher salt, and mix well to draw out excess moisture.

While the squash drains, preheat your oven to 350ºF and start on the béchamel sauce. This creamy sauce is the heart of the casserole, providing flavor and texture. For more inspiration on using zucchini in creative ways, check out this high protein zucchini casserole recipe.

Zucchini and Squash Casserole Recipe: Technique

Technique

Crafting the béchamel sauce begins with melting the remaining unsalted butter in a medium saucepan over medium heat. Add minced garlic and cook until aromatic, about a minute. Next, sprinkle in the all-purpose flour and whisk until the mixture turns lightly golden. This step creates a roux, the base for the béchamel sauce.

Gradually add the whole milk while whisking constantly. This prevents lumps and ensures a smooth sauce. Bring it to a boil over medium-high heat, then lower the heat to maintain a simmer. Continue whisking until the sauce thickens, which should take about 5 to 10 minutes. Remove from heat and stir in paprika, dry mustard, remaining kosher salt, and black pepper.

Tips/tricks

For the best results, ensure the squash is well-drained. Excess moisture can lead to a watery casserole. Squeeze out as much liquid as possible using a clean kitchen towel or paper towels. This step is crucial for achieving the right texture.

Layering is key in this zucchini and squash casserole recipe. Start by pouring a small amount of béchamel sauce at the bottom of the greased baking dish. Then, layer half of the squash, followed by more sauce and fontina cheese. Repeat the layers, finishing with a crispy breadcrumb topping.

Zucchini and Squash Casserole Recipe: Perfecting Results

Perfecting results

Baking the casserole until it bubbles around the edges ensures the flavors meld perfectly. Check after 30 minutes; if the top is browning too quickly, cover with aluminum foil and continue baking. Once done, allow it to cool for 15 minutes before serving to let the flavors settle.

The fontina cheese melts beautifully, adding a creamy richness. Its beefy flavor complements the mild squash, enhancing the overall taste. Grate the cheese using the large holes of a box grater for even melting and distribution.

Troubleshooting/variations

If your casserole turns out watery, it’s likely due to insufficient draining of the squash. Be diligent in removing moisture to avoid this issue. For those seeking a dairy-free option, replace the béchamel sauce with a plant-based alternative. You can also explore this sautéed zucchini recipe for a lighter, quicker dish.

For a different texture, consider adding cooked quinoa or rice between the layers. This adds substance and makes the casserole more filling. Experiment with different cheeses or herbs to suit your taste preferences.
