Savory Squash Casserole

Follow our step-by-step guide on how to make Savory Squash Casserole.

1. Step 1

   Start by preheating your oven to a cozy 350°F (175°C). Grab a 9x13-inch casserole dish and give it a light spray with cooking spray to prevent sticking. This will ensure your casserole comes out perfectly every time!

2. Step 2

   Next, bring a large pot of salted water to a rolling boil. Once boiling, add the sliced yellow squash and let it cook until it's incredibly tender, which should take about 10 to 15 minutes. After that, drain the squash and transfer it to a large mixing bowl. Use a fork or potato masher to mash the squash until it's smooth and creamy.

3. Step 3

   While the squash is cooling a bit, melt the butter in a skillet over medium heat. Add the chopped onion and sauté it until it's tender and fragrant, about 5 to 10 minutes. This step adds a wonderful depth of flavor to your casserole!

4. Step 4

   Now, it's time to bring everything together. In the bowl with the mashed squash, mix in the sautéed onion, cream of mushroom soup, Cheddar cheese, seasoned bread crumbs, milk, mayonnaise, sugar, beaten eggs, and a sprinkle of salt and pepper. Stir until everything is well combined and you have a luscious mixture.

5. Step 5

   Spread this delightful mixture evenly into your prepared casserole dish. Make sure to smooth the top for an even bake.

6. Step 6

   Pop the casserole into your preheated oven and let it bake until it's bubbling and the edges are lightly browned, which should take about 45 minutes to an hour. The aroma will fill your kitchen and have everyone eagerly waiting for dinner!

7. Step 7

   Once it's done, take it out of the oven and let it cool for a few minutes before serving. This casserole is not only delicious but also a fantastic way to enjoy the flavors of summer squash.
