Step-by-Step Guide to Making Summer Squash Casserole

Preparing Your Summer Squash Casserole for Baking
First things first, preheat your oven. Get it to 350°F (175°C). Then, grab a large pot. Add your sliced yellow squash, zucchini, and chopped onion. Pour in enough water to just cover the veggies. Bring it to a boil. Cook until they are tender, about 8-10 minutes. This step is important for texture. Now, drain the squash mixture really well. Squeeze out as much water as you can. This avoids a watery casserole. In a big bowl, combine the cooked squash and onion. Add the melted butter, cream of mushroom soup, shredded Cheddar cheese, milk, salt, and pepper. Mix until everything is perfectly combined. You want no dry spots. This mixture forms the heart of our summer squash casserole.
Baking and Serving Your Delicious Summer Squash Casserole
Now, grab a 9×13 inch baking dish. Spoon your squash mixture evenly into it. Make sure it’s spread out nicely. Next, sprinkle those crushed butter crackers over the top. This will be our beautiful, golden crust. Place the dish into your preheated oven. Bake for 25-30 minutes. You’re looking for bubbly edges and a golden-brown cracker topping. That means it’s ready! Once out of the oven, let it stand for a few minutes. This helps it set up perfectly. Then, scoop out generous portions. Enjoy your homemade summer squash casserole! It’s truly a comforting meal.

Tips for the Best Summer Squash Casserole
I’ve made this summer squash casserole countless times. Along the way, I’ve picked up a few tricks. These little tips can really elevate your dish. They help ensure your casserole is always a hit. For example, if you have a few extra minutes, try sautéing the onion. Do this in a little butter before boiling it with the squash. It deepens the flavor. Also, don’t be afraid to experiment with cheeses. While Cheddar is classic, Colby Jack or Monterey Jack work beautifully too. They add a slightly different creamy tang. Always make sure your squash is well-drained. This prevents a watery casserole. These small steps make a big difference.
Enhancing Your Summer Squash Casserole Flavor
Want to boost the taste of your summer squash casserole even more? Try toasting your crushed crackers. Just a few minutes in a dry pan makes them extra crispy. A pinch of garlic powder mixed into the squash base adds a subtle savory note. You can also sprinkle a little paprika on top. It gives a nice color and a tiny bit of warmth. These simple additions truly make the flavors sing.

Storing your leftover summer squash casserole is easy. Just let it cool completely first. Then, transfer it to an airtight container. Pop it in the refrigerator.
