Tips and Tricks for making the best Southern squash casserole recipe 

Keeping squash casserole from getting watery:

Crafting a squash casserole is a breeze, and these simple suggestions simplify the process, especially if you’re new to the endeavor.

Ensure your squash casserole stays deliciously dry by extracting as much liquid as possible during the initial cooking phase. Strain the cooked squash to eliminate excess water and allow it to cool before incorporating it into the casserole. While sautéing, keep the squash moving, stirring frequently to release steam and avoid browning. These steps are the perfect way to ensure a flavorful and perfectly textured squash casserole on your dinner table every time.

My favorite easy casserole option:

You can slice the squash into 1-4” thick slices or quarter-round pieces and roast them in the oven with a sprinkle of salt and spices. This not only deals with any excess moisture but also results in a delicious touch of caramelization. The whole roasting process truly brings out rich the depth of flavors!

Here are some extra tips on how to prevent squash casserole from becoming watery:

1. Salt and Rest: After slicing the squash, sprinkle it with salt and let it rest for about 15-20 minutes. This draws out excess moisture. Pat the squash dry with paper towels before using it in the casserole.

2. Avoid Overcooking: During the initial sauté or cooking process, be mindful not to overcook the squash. Overcooking can lead to more water being released, affecting the texture of the casserole.

3. Thicker Sauce: Opt for a slightly thicker sauce in your casserole. This can help bind the ingredients together, reducing the chance of excess liquid.

4. Drain Before Mixing: If you notice a significant amount of liquid after salting the squash, consider draining it before mixing it into the casserole. This helps control the moisture content.

5. Breadcrumbs on the Bottom: Placing a layer of breadcrumbs on the bottom of the casserole dish before adding the squash mixture can help absorb any excess moisture during baking.

By incorporating these tips, you can ensure a delicious and not overly watery squash casserole.

Here are some extra quick tips and tricks to elevate your Vegan Squash Casserole:

1. Roasting for Flavor: Consider roasting the squash slices before adding them to the casserole. Roasting enhances the natural sweetness and adds depth to the overall flavor.

2. Seasoning Techniques: Experiment with a variety of seasonings like smoked paprika, nutritional yeast, or a pinch of cayenne for an extra flavor boost.

3. Herb Infusion: Fresh herbs like thyme, rosemary, or basil can bring a burst of freshness. Add them to the casserole or sprinkle on top before baking. Optionally, you can use Italian seasoning as a quick way to infuse the dish with Italian recipes flavor. 

4. Layered Texture: Introduce a layered texture by incorporating a mix of breadcrumbs, crushed nuts, or seeds both in the casserole and on top. This adds a delightful crunch.

5. Creamy Sauce Balance: Achieve the perfect creamy texture by balancing ingredients like almond milk, nutritional yeast, and vegan cheese. Adjust the ratios to your preference.

6. Uniform Slicing: Aim for uniform slicing of the squash to ensure even cooking and a consistent texture throughout the casserole.

7. Serve with Complementary Sides: Pair the casserole with sides like a fresh green salad, garlic bread, or quinoa to create a well-balanced and satisfying meal.

8. Make-Ahead Option: For convenience, prepare the great side dish casserole ahead of time and refrigerate. Add breadcrumbs or crispy crackers just before baking for a fresh, crispy topping to the best squash casserole.

9. Customize with Add-Ins: Personalize your casserole by adding ingredients like spinach, artichoke hearts, or sun-dried tomatoes for extra layers of flavor and incorporate them in between the layers of tender squash.
