Summer Squash Casserole: A Taste of Sunshine

My grandmother, Nana Bess, had a garden overflowing with zucchini and summer squash. As a child, I wasn’t always thrilled with the endless parade of squash dishes, but Nana Bess’s summer squash casserole was different. The creamy texture, the buttery cracker topping, and the sharp cheddar cheese created a comforting symphony of flavors that even my picky palate couldn’t resist. Every bite transported me to her sun-drenched kitchen, filled with the aroma of garden herbs and the warmth of her love. This recipe is my tribute to her, a way to keep her memory alive and share a taste of her sunshine with the world.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 4
• Yield: 1 casserole
• Dietary Type: Vegetarian

Ingredients

• 1 1⁄2 lbs summer squash
• 1⁄2 cup butter or margarine
• 1 egg
• 1 medium onion, chopped
• Salt and pepper to taste
• 12-15 Ritz crackers, crushed
• 3⁄4 cup grated cheddar cheese or longhorn cheese

Equipment Needed

• Large pot
• Potato masher
• Cutting board
• Knife
• 9×13 inch casserole dish
• Measuring cups and spoons

Instructions

1. Begin by preparing the summer squash. Peel and de-seed the squash. This step is crucial, especially if the squash is mature, as the seeds can be tough and detract from the casserole’s creamy texture.

2. Next, cut the prepared squash into large cubes. The size doesn’t need to be precise, as they will be mashed later.

3. Place the cubed squash in a large pot and boil until tender. This usually takes about 15-20 minutes. You should be able to easily pierce the squash with a fork when it’s ready.

4. Once the squash is tender, drain it thoroughly. It’s important to remove as much excess water as possible to prevent the casserole from becoming soggy.

5. Return the drained squash to the pot and mash it thoroughly using a potato masher. You can leave it slightly chunky for a more rustic texture, or mash it completely smooth for a creamier result.

6. Add the butter or margarine to the mashed squash. The heat from the squash will melt the butter, making it easier to incorporate.

7. Now, add the egg, chopped onion, salt, and pepper. Stir well to combine all the ingredients. Taste and adjust the seasonings as needed.

8. Crush the Ritz crackers. You can do this by placing them in a zip-top bag and crushing them with a rolling pin, or by using a food processor for a finer crumb.

9. Add the crushed Ritz crackers to the squash mixture and stir until well combined. The crackers act as a binder and add a lovely buttery flavor.

10. Butter a casserole dish. This will prevent the casserole from sticking and make it easier to serve. A 9×13 inch dish is ideal, but you can also use a smaller dish if that’s what you have.

11. Pour the squash mixture into the prepared casserole dish, spreading it evenly.

12. Sprinkle the grated cheddar cheese or longhorn cheese evenly over the top of the casserole. The cheese will melt and create a golden-brown, bubbly topping.

13. Bake in a preheated oven at 350 degrees Fahrenheit until the cheese is melted and bubbly, and the edges of the casserole are golden brown. This usually takes about 25 minutes.

14. To check for doneness, look for bubbles appearing around the edges of the casserole and a golden-brown color on top. A toothpick inserted into the center should come out relatively clean.

15. Remove from the oven and let it cool slightly before serving. This allows the casserole to set up a bit and makes it easier to slice.

Expert Tips & Tricks

• For extra flavor, sauté the chopped onion in a little butter before adding it to the squash mixture. This will mellow the onion’s flavor and add a touch of sweetness.
• If you don’t have Ritz crackers, you can substitute other buttery crackers, such as club crackers or saltines.
• To prevent the cheese from browning too quickly, you can tent the casserole dish with foil during the last 10 minutes of baking.
• For a spicier casserole, add a pinch of red pepper flakes or a dash of hot sauce to the squash mixture.
• Make ahead: The squash mixture can be prepared ahead of time and stored in the refrigerator for up to 24 hours. Add the cheese topping just before baking.

Serving & Storage Suggestions

Serve the summer squash casserole hot or warm as a side dish. It pairs perfectly with grilled chicken, pork, or fish. It’s also a delicious addition to a vegetarian meal. Garnish with fresh parsley or chives for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 30-second intervals until heated through, or bake in a preheated oven at 350 degrees Fahrenheit until warmed.

Freezing is not recommended, as the texture of the squash can change after thawing.
