  • ½ cup diced onion

• Dairy

  • ¼ cup butter
  • ½ cup sour cream
  • 1 large egg (beaten)
  • 1 cup shredded cheddar cheese
  • ½ cup grated Parmesan cheese

• Seasonings

  • ½ teaspoon garlic powder
  • ¾ teaspoon salt

How to Make Southern Squash Casserole

1. Sauté the Onions
   In a large pan set over medium heat, melt 1 tablespoon of butter. Add the diced onion and sauté for 7-8 minutes, or until soft and translucent.

2. Cook the Squash
   Add the sliced yellow squash to the pan and cook for 10-12 minutes, stirring frequently to prevent browning and to help release moisture. The squash should be soft when done.

3. Drain Excess Moisture
   Place a towel in a colander to catch the squash and onions. Transfer them to the towel and drain for at least 5 minutes, pressing out any excess moisture.

4. Mix the Ingredients
   In a mixing bowl, combine the drained squash and onions with garlic powder, salt, black pepper, sour cream, beaten egg, shredded cheddar cheese, and half of the grated Parmesan cheese.

5. Prepare the Topping
   In a separate bowl, melt the remaining 3 tablespoons of butter. Stir in the crushed crackers and the remaining ¼ cup of Parmesan cheese until the mixture is well combined.

6. Assemble the Casserole
   Scrape the squash mixture into a 1.5-quart baking dish (like an 8×8 square). Sprinkle the butter and cracker mixture evenly over the top.

7. Bake the Casserole
   Bake in a preheated oven at 350°F for 25 minutes or until it’s bubbly and golden on top.

Tips for Success

• Monitor Cooking Time: Ensure you do not overcook the squash while sautéing; it should be tender but not mushy to maintain texture in the casserole.

• Proper Draining: Taking the time to thoroughly drain the squash mixture helps prevent a watery casserole, which can occur if too much moisture remains.

• Use Fresh Ingredients: Fresh yellow squash will yield the best flavor and texture. Avoid overripe squash for optimal results.

• Don’t Skip the Topping: The butter cracker topping adds a wonderful crunch that contrasts beautifully with the creamy filling in the casserole.

Easy Variations

1. Add Protein: Incorporate cooked ground turkey, chicken, or crumbled sausage for a heartier main dish.

2. Switch Up the Cheese: Experiment with different cheeses like mozzarella or feta for unique flavor profiles.

3. Spice It Up: Add a pinch of red pepper flakes or some diced jalapeños for a bit of heat.

4. Vegetable Add-Ins: You can also mix in other vegetables, such as diced bell peppers or corn, for added flavor and nutrition.

5. Make It Gluten-Free: Substitute regular butter crackers with gluten-free crackers to cater to dietary preferences.

What to Serve with Southern Squash Casserole

1. Grilled Chicken: A simple grilled chicken breast pairs wonderfully with this casserole, complementing its rich flavors without overwhelming them.

2. Roasted Pork Tenderloin: The savory flavors of roasted pork tenderloin work harmoniously with the creamy squash.

3. Herb-Roasted Potatoes: Crispy roasted potatoes add a satisfying crunch and are a classic side dish to enjoy alongside the casserole.

4. Fresh Salad: A light garden salad with a lemon vinaigrette cuts through the richness of the casserole, refreshing the palate.

5. Baked Fish: A light and flaky baked fish brings a lovely balance to the meal, making the dish feel lighter.

Storage and Reheating

• Refrigerator Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.

• Freezer Storage: If you need to freeze it, wrap the cooled casserole tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months.

• Best Reheating Method: Reheat in the oven at 350°F for about 20-25 minutes, or until heated through. If reheating from frozen, cook until it is thoroughly warmed, about 45 minutes.

• Preserving Texture: Cover the dish with aluminum foil to prevent the top from over-browning while reheating.

Common Mistakes to Avoid

1. Overcooking the Squash: This can lead to a mushy texture in the final dish; cook just until tender.

2. Skipping the Draining Step: Not draining the squash mixture can result in excess moisture, making the casserole soggy.

3. Choosing the Wrong Dish: Using a dish that’s too small can cause overflow in the oven if the casserole bubbles up.

4. Not Preheating the Oven: Ensuring the oven is preheated before baking the casserole is essential for even cooking.
