Best Squash Casserole (Southern-Style & Delicious)
A comforting and delicious squash casserole that is creamy, cheesy, and perfect for gatherings or as a side dish.
Ingredients
Vegetable Base
- 2 1/2 pounds yellow squash, cut into 1/4 inch slices
- 1 cup onion, diced
- 2 cloves garlic, minced
Creamy Sauce
- 1/2 cup mayonnaise
- 1/2 cup sour cream
- 1/2 cup milk
- 2 large eggs
- 1/4 teaspoon cayenne pepper
- 1/2 cup parmesan cheese, grated
- 2 cups colby Jack cheese, shredded
- 1/2 teaspoon dried thyme
Topping
- 1 sleeve Ritz crackers, crushed
- 4 tablespoons butter, melted
Instructions
Preparation
- Preheat your oven to 350°F (175°C) and spray an 8x8 baking dish with nonstick cooking spray.
- In a large skillet over medium-high heat, add 2 tablespoons of butter.
- Add the sliced squash and diced onion to the skillet and cook until soft, about 8 minutes. Add in the minced garlic and cook for an additional 30 seconds. Remove from heat.
- Place the cooked squash in a colander and stir to remove as much liquid as possible. Let it drain for about 10 minutes.
Mixing
- In a small bowl, mix together the mayonnaise, sour cream, milk, eggs, parmesan cheese, colby cheese, cayenne, salt, pepper, and thyme until combined.
- In another bowl, mix the crushed Ritz crackers with melted butter until the crackers are coated.
Assembly
- Add 1/3 of the sauce to the bottom of the casserole dish, followed by half of the squash, another 1/3 of the sauce, the remaining squash, and then the rest of the sauce on top.
- Spread the crushed crackers over the top.
Baking
- Bake in the preheated oven for 25-30 minutes or until golden brown and cooked through.
Notes
Make sure to squeeze out as much moisture from the squash as possible to prevent the casserole from being watery. Feel free to experiment with different cheeses, such as cheddar or mozzarella, for varied flavors. Add cooked bacon or sausage for extra heartiness. You can use zucchini alongside yellow squash for a colorful variation.
