What is Squash Casserole?

Squash casserole is a baked dish featuring squash as the primary ingredient. Typically, yellow squash or zucchini is used, often combined with onions, cheese, and a creamy sauce.

Squash casserole is often served as a side dish, especially during holidays and potlucks, but it can also be a satisfying vegetarian main course.

Choosing the Right Squash

While yellow squash is the most common choice for squash casserole, you can also use zucchini, pattypan squash, or a combination of different squashes. Here’s a breakdown:

* **Yellow Squash:** This squash has a mild, slightly sweet flavor and a tender texture when cooked. It’s the classic choice for squash casserole.

When choosing squash, look for firm, unblemished vegetables with smooth skin. Avoid squash that is soft or has bruises.

Classic Squash Casserole Recipe

This is a classic recipe for squash casserole that serves as a great starting point for your culinary adventures.

**Ingredients:**

* 2 pounds yellow squash, sliced
* 1 medium onion, chopped
* 1/2 cup butter, divided
* 1 (10.75 ounce) can condensed cream of chicken soup
* 1 cup sour cream
* 1 cup shredded cheddar cheese, divided
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper
* 1 sleeve Ritz crackers, crushed

**Instructions:**

1. **Prepare the Squash:** In a large pot, combine the sliced squash, onion, and 1/4 cup of butter. Cook over medium heat until the squash is tender, about 10-15 minutes. Stir occasionally to prevent burning. You can also steam the squash to retain more nutrients. Simply place the sliced squash and onion in a steamer basket over boiling water and cook until tender. Steaming usually takes about 8-12 minutes.

2. **Make the Sauce:** In a large bowl, combine the condensed cream of chicken soup, sour cream, 1/2 cup of shredded cheddar cheese, salt, and pepper. Mix well.

3. **Combine Squash and Sauce:** Drain any excess liquid from the cooked squash. Add the squash and onion mixture to the sauce and stir gently to combine.

4. **Prepare the Topping:** In a separate bowl, melt the remaining 1/4 cup of butter. Add the crushed Ritz crackers and mix until the crackers are coated in butter. Alternatively, you can use a food processor to crush the crackers and then drizzle the melted butter over them. Toss to coat evenly.

5. **Assemble the Casserole:** Pour the squash mixture into a greased 9×13 inch baking dish. Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top, followed by the crushed Ritz cracker topping.

6. **Bake:** Bake in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the topping is golden brown and the casserole is bubbly.

7. **Cool and Serve:** Let the casserole cool for a few minutes before serving. This allows the flavors to meld together and prevents burning your mouth.

Tips for Perfect Squash Casserole

* **Don’t Overcook the Squash:** Overcooked squash will become mushy. Cook it until it’s tender but still has some texture.
* **Drain Excess Liquid:** Squash releases a lot of moisture as it cooks. Be sure to drain any excess liquid before adding it to the sauce to prevent a watery casserole. You can drain the squash by placing it in a colander after cooking or by gently pressing it with a spoon.
* **Use Fresh Ingredients:** Fresh squash and onions will give you the best flavor.
* **Adjust Seasoning:** Taste the sauce before adding the squash and adjust the seasoning as needed. You may want to add more salt, pepper, or other spices to suit your taste.
* **Grease the Baking Dish:** This will prevent the casserole from sticking to the dish.
* **Don’t Overcrowd the Baking Dish:** Overcrowding can lead to uneven cooking. Use a 9×13 inch dish for the recommended amount of ingredients. If you’re making a larger batch, use a larger dish or divide the mixture into two smaller dishes.
* **Let it Rest:** Allowing the casserole to rest for a few minutes after baking will help it set up and make it easier to serve.

Make-Ahead Instructions

Squash casserole is a great dish to make ahead of time. You can assemble the casserole up to 24 hours in advance and store it in the refrigerator. When you’re ready to bake, simply remove it from the refrigerator and bake as directed. You may need to add a few minutes to the baking time if the casserole is cold. It’s best to add the topping just before baking to prevent it from getting soggy. If you’ve already added the topping, you can cover the casserole with foil during the first part of baking to prevent it from browning too quickly.

Freezing Instructions

You can also freeze squash casserole for longer storage. Assemble the casserole in a freezer-safe dish and wrap it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. When you’re ready to bake, thaw the casserole in the refrigerator overnight. Bake as directed, adding a few minutes to the baking time if necessary. It’s best to add the topping just before baking for the best texture. If you’ve already added the topping, you can cover the casserole with foil during the first part of baking to prevent it from browning too quickly.

Serving Suggestions

Squash casserole is a versatile side dish that pairs well with a variety of main courses. Here are some serving suggestions:

Troubleshooting

* **Casserole is Too Watery:** This is usually caused by not draining enough liquid from the squash. Next time, be sure to drain the squash thoroughly after cooking. You can also add a thickening agent, such as cornstarch or flour, to the sauce.
