Step-by-Step Squash Casserole Recipe

Once you’ve gathered your ingredients, follow these easy steps to create a mouthwatering squash casserole your family will love.

Step 1: Prep the Squash

Wash the squash thoroughly and trim off the ends. Slice the squash into thin, uniform rounds. This will help ensure even cooking.

Step 2: Sauté the Vegetables

Heat a large skillet over medium heat. Melt 2 tablespoons of butter and sauté the sliced squash and onion until they are softened about 10-12 minutes. Season lightly with salt and pepper while sautéing. Once cooked, set the mixture aside to cool slightly.

Step 3: Make the Creamy Base

In a large mixing bowl, combine the eggs, shredded cheddar cheese, and sour cream. Mix well until fully incorporated.

Step 4: Combine the Mixtures

Add the cooled squash and onion mixture to the creamy base. Gently stir to ensure the squash is evenly coated.

Step 5: Prepare the Casserole

Lightly grease a 9x9-inch baking dish (or similar casserole dish). Pour the squash mixture into the dish and spread it out evenly.

Step 6: Add the Topping

Sprinkle the crushed crackers evenly over the top of the squash mixture. Drizzle with the remaining tablespoon of melted butter for extra crispiness.

Step 7: Bake

Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 25-30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 8: Serve

Remove the casserole from the oven and allow it to cool slightly before serving. Pair it with roasted meats, and frand esh salads, or serve it solo as a comforting vegetarian option.

Pro Tips for the Perfect Squash Casserole

• Don’t Skip the Sauté: Cooking the squash beforehand removes excess water and ensures the casserole isn’t too soggy.
• Use Fresh Squash: The fresher your squash, the better the flavor and texture.
• Experiment with Toppings: Try crushed seasoned croutons or cheese-dusted panko for a unique twist.
• Prep Ahead of Time: You can assemble the casserole up to a day in advance. Just refrigerate it (unbaked) and bake it fresh the next day.

Squash Casserole Variations

Want to take creative liberties? Here are some variations to suit different tastes:

• Gluten-Free Squash Casserole

Switch crushed crackers for gluten-free panko, or skip the topping altogether.

• Lower-Calorie Version

Use reduced-fat sour cream, skip the butter drizzle on the topping, and halve the cheese.

• Vegan-Friendly Option

Substitute the eggs with a flaxseed or chia egg, use plant-based sour cream and cheese, and choose vegan-friendly breadcrumbs or crackers.
