Squash Casserole

Whenever I think of comfort food, the first thing that comes to mind is my beloved Squash Casserole. It’s more than just a dish; it’s a warm hug that brings back memories of cozy family dinners during the crisp fall evenings. The aroma of sautéing onions and tender squash wafting through the kitchen feels like a gentle reminder of home. I can still hear the laughter and chatter as we gathered around the table, eagerly anticipating that first bite of creamy, cheesy goodness. This casserole has a special place in my heart because it’s not just delicious; it’s a celebration of seasonal produce that transforms simple ingredients into something extraordinary.

What You’ll Need for Squash Casserole

Gathering the right ingredients is key to making a fantastic Squash Casserole. Each ingredient plays a vital role in creating a beautifully balanced dish. The combination of fresh vegetables, creamy dairy, and spices ensures that every bite is packed with flavor. Let’s dive into the ingredients that make this casserole a must-try.

• 4 tablespoons unsalted butter (divided) – This fat adds richness and depth to the dish, helping to sauté the onions and coat the casserole.
• 1 medium yellow onion (chopped, about 1 ½ cups) – The onion provides a sweet and savory base that enhances the overall flavor.
• 4 medium yellow squash (cut into ¼-inch thick coins, about 3 pounds) – The star of the dish, yellow squash adds a mild sweetness and pleasant texture.
• 1 ½ teaspoons kosher salt (divided) – Essential for seasoning, it helps to draw out the flavors of the vegetables.
• 2 large eggs – These bind the ingredients together and contribute to the casserole’s texture.
• 1 (5.3-ounce) container full-fat plain Greek yogurt (about ½ cup) – Adds creaminess while keeping the dish light and tangy.
• ⅔ cup milk – This liquid helps create a rich, creamy filling.
• ½ teaspoon ground black pepper – Provides a subtle kick that enhances the dish’s overall flavor.
• ¼ teaspoon dried thyme – Adds an earthy, aromatic quality that complements the squash.
• ⅛ to ¼ teaspoon cayenne pepper – A touch of heat that offsets the sweetness of the squash.
• ⅔ cup shredded sharp cheddar cheese – This cheese melts beautifully and adds a rich, tangy flavor.
• ⅓ cup shredded Swiss cheese (or additional cheddar cheese) – Offers a unique flavor profile and helps achieve that gooey, cheesy texture.
• 1 sleeve round buttery crackers (such as Ritz, coarsely crushed, about 1 ½ cups) – The topping adds a delightful crunch and buttery finish to the casserole.

Instructions for Squash Casserole

Cooking the Squash Casserole is a rewarding experience that fills your kitchen with enticing aromas. Follow these steps to create a hearty dish that will surely be a hit. Let’s get started!

1. Preheat your oven to 350 degrees F. This initial step is crucial to ensure your casserole bakes evenly. While the oven is heating, coat an 8×10 or similar casserole dish with nonstick spray to prevent sticking.
2. Melt 2 tablespoons of the butter in a large skillet over medium-high heat. As the butter melts, it will create a beautiful base for your onions. Add the onion and cook until they begin to soften, about 5 minutes. You’ll notice a sweet aroma filling your kitchen.
3. Next, add the yellow squash and 1 teaspoon of the salt. Stir frequently, allowing the squash to cook until it’s just tender and starting to brown for about 10 minutes. The color change is a good indicator that they’re almost done.
4. Once your squash is ready, transfer the mixture to a colander set over a bowl or in the sink. This step is essential as it allows any excess liquid to drain, resulting in a firmer casserole. Let it drain for at least 5 minutes, gently shaking off as much liquid as possible.
5. In a large bowl, whisk together the eggs, Greek yogurt, milk, black pepper, thyme, cayenne pepper, and the remaining ½ teaspoon salt. This mixture will bring all the flavors together. You want a smooth consistency before adding the next ingredients.
6. Add the drained cheddar, Swiss, and squash mixture to the bowl. Gently stir to combine everything. Be cautious not to overmix, as you want to maintain some texture from the squash.
7. Transfer the combined mixture to the prepared baking dish. Spread it out evenly, ensuring that each bite contains a blend of all the ingredients.
8. In a medium microwave-safe bowl, melt the remaining 2 tablespoons of butter. Once melted, add the crushed crackers and stir until they’re evenly moistened. This topping will provide a delightful crunch!
9. Spoon the cracker mixture over the top of the casserole, ensuring it’s evenly distributed. This layer is what gives the casserole that classic, crispy topping.
10. Bake the Squash Casserole in the preheated oven until the filling is fully set at the edges and only slightly liquidy when you check the center with a knife, about 30 to 35 minutes. Once baked, let it rest for 10 minutes before serving. This waiting period allows the casserole to set properly and makes for easier serving.

Ways to Customize

The Squash Casserole is not only delicious but also incredibly customizable. Here are some ideas to make this dish your own!

• Add Protein: Consider adding cooked chicken or turkey for a heartier meal. Simply mix it in with the squash.

• Cheese Variations: Substitute with different cheeses, like mozzarella for a milder flavor or pepper jack for a spicy kick.
• Herb Infusion: Incorporate fresh herbs like basil or parsley to elevate the dish’s freshness.
• Change the Topping: Swap out the cracker topping for breadcrumbs or even crushed nuts for an extra crunch.
• Spice it Up: Add diced jalapeños or red pepper flakes if you love a little heat.
