Summer Squash Casserole Recipe

Summer squash: A tender, mild-flavored vegetable that forms the base of the casserole.

Onion: Adds a sweet and savory flavor to the dish.

Shredded cheddar cheese: Provides a rich, creamy taste and helps bind the casserole together.

Sour cream: Adds creaminess and a slight tang to the mixture.

Crackers: Crushed crackers create a crunchy topping and add texture to the casserole.

Butter: Melted butter is drizzled over the top to enhance the flavor and help the topping brown.

Salt: Enhances the overall flavor of the dish.

Pepper: Adds a bit of heat and depth to the flavor.

When boiling the summer squash and onion, make sure to not overcook them. They should be tender but still hold their shape. Overcooking can lead to a mushy texture in the final casserole. To ensure even cooking, slice the squash uniformly and chop the onion into similar-sized pieces.

• sliced summer squash - Substitute with zucchini: Zucchini has a similar texture and mild flavor, making it an excellent replacement for summer squash.

• chopped onion - Substitute with shallots: Shallots provide a slightly sweeter and more delicate flavor compared to onions, which can add a subtle complexity to the dish.

• shredded cheddar cheese - Substitute with shredded Monterey Jack cheese: Monterey Jack melts well and has a mild flavor that complements the other ingredients without overpowering them.

• sour cream - Substitute with Greek yogurt: Greek yogurt offers a similar creamy texture and tangy flavor while being lower in fat and higher in protein.

• crushed crackers - Substitute with panko breadcrumbs: Panko breadcrumbs provide a light and crispy texture, making them a great alternative to crushed crackers.

• melted butter - Substitute with olive oil: Olive oil can be used to add a rich flavor and healthy fats, making it a suitable replacement for melted butter.

• salt - Substitute with soy sauce: Soy sauce can add a depth of umami flavor while also providing the necessary saltiness.

• pepper - Substitute with cayenne pepper: Cayenne pepper can add a bit of heat and spice, offering a different dimension of flavor to the casserole.

• Allow the summer squash casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.

• Transfer the cooled casserole into an airtight container. If you prefer, you can also use heavy-duty aluminum foil or plastic wrap to cover the baking dish tightly.

• Store the casserole in the refrigerator if you plan to consume it within 3-4 days. The flavors will meld beautifully, making it even more delicious.

• For longer storage, consider freezing the casserole. Wrap it tightly with plastic wrap, then cover with a layer of aluminum foil to prevent freezer burn.

• Label the container with the date and contents to keep track of its freshness. This is especially useful if you have multiple dishes stored.

• When ready to reheat, if frozen, thaw the casserole in the refrigerator overnight. This ensures even reheating and maintains the dish's texture.

• Preheat your oven to 350°F (175°C) and bake the thawed casserole for about 20-25 minutes, or until heated through. If reheating from the refrigerator, it may take slightly less time.

• To keep the crushed cracker topping crispy, consider adding a fresh layer of crackers and a drizzle of melted butter before reheating.

• If you prefer microwave reheating, transfer a portion to a microwave-safe dish, cover loosely, and heat on medium power in 1-2 minute intervals until warmed through. Stir occasionally for even heating.

• Enjoy your reheated summer squash casserole as a delightful side dish or a comforting main course.

• Preheat your oven to 350°F (175°C). Place the summer squash casserole in an oven-safe dish, cover it with aluminum foil to prevent it from drying out, and bake for about 20-25 minutes or until heated through.

• For a quicker option, use the microwave. Transfer a portion of the casserole to a microwave-safe dish, cover it with a microwave-safe lid or plastic wrap (leaving a small vent), and heat on medium power for 2-3 minutes. Stir halfway through to ensure even heating.

• If you prefer a crispy topping, reheat the casserole in a skillet. Place a portion in a non-stick skillet over medium heat, cover, and cook for about 5-7 minutes. Stir occasionally to avoid burning and ensure even heating.

• For an air fryer method, preheat the air fryer to 350°F (175°C). Place a portion of the casserole in the air fryer basket, and heat for 5-7 minutes. Check halfway through to ensure it doesn't overcook and retains its crispy top.

Pre-cook the squash: Boil the summer squash and onion in advance and store them in the fridge. This will save you time on the day you plan to make the casserole.

Use pre-shredded cheese: Opt for pre-shredded cheddar cheese to cut down on prep time.

Crush crackers in bulk: Crush a large batch of crackers and store them in an airtight container. This way, you have them ready for multiple recipes.

Melt butter in the microwave: Quickly melt the butter in the microwave instead of on the stove to save a few minutes.
