## Ingredients You’ll Need

Before we get started, let’s gather all the necessary ingredients. This recipe is straightforward and uses readily available items, ensuring that anyone can recreate this delicious casserole at home.

* **Summer Squash (Yellow Squash):** 3 pounds, about 5-6 medium squash, washed and sliced.
* **Onion:** 1 medium, chopped.
* **Butter:** 1/2 cup (1 stick), divided into 4 tablespoons and 4 tablespoons.
* **All-Purpose Flour:** 1/4 cup
* **Milk:** 1 cup
* **Eggs:** 2 large, lightly beaten.
* **Sour Cream:** 1 cup
* **Sharp Cheddar Cheese:** 2 cups, shredded, divided.
* **Salt:** 1 teaspoon, or to taste.
* **Black Pepper:** 1/2 teaspoon, or to taste.
* **Garlic Powder:** 1/4 teaspoon
* **Cracker Crumbs:** 1 cup (Ritz crackers or similar buttery crackers work best).

**Ingredient Notes and Substitutions:**

* **Squash:** While yellow squash is traditional, you can also use zucchini or a mix of both. The key is to have about 3 pounds of sliced squash.
* **Onion:** Yellow or white onions work well. For a milder flavor, you can use sweet onions.
* **Cheese:** Sharp cheddar provides a classic flavor, but you can experiment with other cheeses like Monterey Jack, Colby Jack, or even a blend of cheeses.
* **Cracker Crumbs:** Ritz crackers are preferred for their buttery flavor, but you can use other buttery crackers or even bread crumbs. If using bread crumbs, consider adding a tablespoon or two of melted butter for extra flavor.
* **Sour Cream:** Full-fat sour cream is recommended for its richness, but you can use low-fat sour cream if you prefer.
* **Milk:** Whole milk will result in a creamier casserole, but you can use 2% or even skim milk.

## Equipment You’ll Need

Having the right equipment will make the cooking process smoother and more enjoyable.

* **Large Skillet or Dutch Oven:** For sautéing the squash and onion.
* **9×13 inch Baking Dish:** For baking the casserole.
* **Mixing Bowls:** For combining ingredients.
* **Measuring Cups and Spoons:** For accurate measurements.
* **Knife and Cutting Board:** For chopping the onion and slicing the squash.
* **Cheese Grater:** For shredding the cheese.
* **Wooden Spoon or Spatula:** For stirring the ingredients.

## Step-by-Step Instructions

Now that we have our ingredients and equipment ready, let’s get started on making Mama’s Summer Squash Casserole. Follow these detailed steps for a perfect casserole every time.

**Step 1: Prepare the Squash and Onion**

1. Wash the squash thoroughly and trim off the ends.
2. Slice the squash into 1/4-inch thick rounds or half-moons. Uniform slices ensure even cooking.
3. Peel and chop the onion into small, even pieces.

**Step 2: Sauté the Squash and Onion**

1. Melt 4 tablespoons of butter in a large skillet or Dutch oven over medium heat.
2. Add the chopped onion and sauté until softened and translucent, about 5-7 minutes. Stir occasionally to prevent burning.
3. Add the sliced squash to the skillet. Season with salt, pepper, and garlic powder. Stir to combine.
4. Cook the squash until it is tender and slightly softened, about 10-15 minutes. Stir occasionally to ensure even cooking and prevent sticking. The squash should release some of its moisture during this process.
5. Once the squash is tender, remove the skillet from the heat and set aside.

**Step 3: Make the Cream Sauce**

1. In a separate saucepan, melt the remaining 4 tablespoons of butter over medium heat.
2. Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which will thicken the sauce. Be careful not to burn the flour.
3. Gradually whisk in the milk, stirring constantly to prevent lumps from forming. Continue stirring until the sauce thickens and becomes smooth, about 3-5 minutes.
4. Remove the saucepan from the heat.

**Step 4: Combine the Ingredients**

1. In a large mixing bowl, combine the cooked squash and onion mixture with the cream sauce.
2. Add the beaten eggs and sour cream to the bowl. Stir gently to combine everything thoroughly.
3. Add 1 1/2 cups of the shredded cheddar cheese to the mixture. Reserve the remaining 1/2 cup of cheese for topping the casserole.
4. Stir everything together until well combined. Taste and adjust the seasoning with additional salt and pepper, if needed.

**Step 5: Prepare the Cracker Topping**

1. Crush the crackers into fine crumbs. You can use a food processor, a rolling pin, or simply crush them in a plastic bag.
2. In a small bowl, combine the cracker crumbs with the remaining 1/2 cup of shredded cheddar cheese. Mix well.

**Step 6: Assemble and Bake the Casserole**

1. Preheat your oven to 350°F (175°C).
2. Grease a 9×13 inch baking dish with butter or cooking spray.
3. Pour the squash mixture into the prepared baking dish, spreading it evenly.
4. Sprinkle the cracker crumb and cheese topping evenly over the top of the casserole.
5. Bake in the preheated oven for 30-40 minutes, or until the casserole is golden brown and bubbly. The topping should be nicely browned, and the cheese should be melted and slightly golden.

**Step 7: Let it Rest and Serve**

1. Once the casserole is done, remove it from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set slightly and makes it easier to slice.
2. Serve hot and enjoy! This casserole pairs well with grilled chicken, pork chops, or your favorite Southern sides.

## Tips for the Perfect Casserole

* **Don’t Overcook the Squash:** Overcooked squash can become mushy. Cook it until it’s tender but still has a bit of bite.
* **Drain Excess Moisture:** If the squash releases a lot of moisture while cooking, drain it slightly before adding it to the casserole mixture. This will prevent the casserole from becoming too watery.
* **Use Fresh Ingredients:** Fresh summer squash and good quality cheese will make a big difference in the flavor of the casserole.
* **Adjust Seasoning to Taste:** Taste the casserole mixture before baking and adjust the seasoning with salt, pepper, and garlic powder as needed. Everyone’s taste preferences are different, so don’t be afraid to experiment.
* **Make it Ahead:** You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Add the cracker topping just before baking to prevent it from becoming soggy. You may need to add 10-15 minutes to the baking time if baking from cold.
* **Customize the Topping:** Get creative with the topping! Try adding chopped pecans, walnuts, or even a sprinkle of paprika for added flavor and texture.

## Variations and Additions

Mama’s Summer Squash Casserole is delicious as is, but feel free to customize it to your liking with these variations and additions:

* **Add Protein:** Incorporate cooked chicken, ground beef, or sausage for a heartier meal.
* **Spice it Up:** Add a pinch of red pepper flakes or a dash of hot sauce for a little heat.
* **Add More Vegetables:** Include other vegetables like bell peppers, corn, or tomatoes for added flavor and nutrition.
* **Use Different Cheeses:** Experiment with different cheeses like Gruyere, Parmesan, or pepper jack for a unique flavor profile.
* **Make it Gluten-Free:** Use gluten-free cracker crumbs or almond flour for the topping.
* **Make it Vegetarian:** Ensure that the cheese used is vegetarian-friendly, as some cheeses use animal rennet.

## Serving Suggestions

Mama’s Summer Squash Casserole is a versatile dish that can be served as a side dish or a main course. Here are some serving suggestions:

* **As a Side Dish:** Serve alongside grilled chicken, pork chops, roasted turkey, or ham.
* **As a Main Course:** Pair it with a side salad and some crusty bread for a complete meal.

## Storage Instructions

* **Refrigerating:** Leftover casserole can be stored in the refrigerator for up to 3-4 days. Cover it tightly with plastic wrap or store it in an airtight container.
* **Reheating:** Reheat the casserole in the oven at 350°F (175°C) until heated through, about 15-20 minutes. You can also reheat it in the microwave in short intervals, stirring occasionally.
* **Freezing:** While the texture may change slightly, you can freeze the casserole for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil. Thaw it in the refrigerator overnight before reheating.
