Yellow Squash Casserole Recipe

Yellow squash: A tender and mild-flavored vegetable that forms the base of the casserole.

Onion: Adds a savory depth of flavor to the dish.

Cheddar cheese: Provides a rich and creamy texture with a sharp taste.

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

Crushed crackers: Creates a crunchy topping that contrasts with the creamy filling.

Butter: Used to drizzle over the cracker topping for added richness.

Salt: Enhances the overall flavor of the dish.

Pepper: Adds a hint of spice and balances the flavors.

When preparing the yellow squash and onion, make sure to slice them evenly. This ensures that they cook uniformly, resulting in a consistent texture throughout the casserole. Additionally, after boiling, drain the vegetables thoroughly to avoid excess moisture, which can make the casserole soggy. For an extra layer of flavor, consider lightly toasting the crushed crackers before sprinkling them on top. This will add a delightful crunch and a deeper, nutty taste to the dish.

• Allow the yellow squash casserole to cool completely at room temperature before storing.
• Transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil.
• Store in the refrigerator for up to 3-4 days. Reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
• For freezing, portion the casserole into individual servings or keep it whole. Wrap each portion or the entire dish tightly with plastic wrap, then with aluminum foil to prevent freezer burn.
• Label the wrapped casserole with the date and contents for easy identification.
• Freeze for up to 2-3 months. To reheat, thaw in the refrigerator overnight. Reheat in the oven at 350°F (175°C) until hot and bubbly, about 25-30 minutes.
• For a quicker reheating option, use the microwave. Place a portion of the casserole in a microwave-safe dish, cover with a microwave-safe lid or plastic wrap, and heat on medium power until warmed through, stirring occasionally.

• Preheat your oven to 350°F (175°C). Place the leftover yellow squash casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. 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 a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.

• If you prefer a crispy top, use a toaster oven. Preheat the toaster oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover it with foil. Heat for 15-20 minutes, then remove the foil and continue to bake for an additional 5 minutes to crisp up the crushed crackers topping.

• For stovetop reheating, use a non-stick skillet over medium heat. Add a small amount of butter or olive oil to the skillet. Place the casserole in the skillet and cover with a lid. Heat for about 10 minutes, stirring occasionally, until warmed through.

• If you have an air fryer, preheat it to 350°F (175°C). Place the casserole in an air fryer-safe dish. Heat for 10-15 minutes, checking halfway through to ensure it doesn't overcook. This method will help maintain a crispy topping.
