Easy Squash Casserole Recipe

Thanksgiving is right around the corner. I am already looking forward to the holiday meal! I know turkey is the star of the meal, but I love all the side dishes! This Cheesy Squash Casserole is definitely going to be on our holiday table! Squash, onion, bell pepper, eggs, and tons of cheese! It is super easy to make and tastes great!

This casserole makes a great side dish or vegetarian main dish! It is almost like a squash quiche without the crust. We love this recipe! It is great at the holidays and any other day of the year.

How to Make Cheesy Squash Casserole

This casserole is very easy to make. Start by sauteing sliced squash, bell pepper, and onion in a large skillet. You want to cook it until it is nice and soft. Once the veggies are cooked transfer them to a strainer and press down to get all of the liquid out. Squash is very watery, you want to make sure to get as much of the liquid out as possible. Next, combine flour, baking powder, salt, milk, and eggs. Add the cooked squash mixture and the cheese. Transfer the mixture to a baking dish and pop in the oven. 

• I used Monterey Jack and Cheddar cheese in this casserole. Feel free to kick it up with some Pepper Jack cheese if you want to kick it up a bit. You can also add a can of diced green chiles. YUM!
• Can Squash Casserole be made in advance? Yes! You can make this casserole ahead of time and refrigerate overnight. To bake after refrigerating, let the casserole dish sit on the counter for 30 minutes before baking.
• Can Squash Casserole be frozen? Yes! You can make this casserole ahead of time and freeze unbaked for later. To bake after freezing, thaw the casserole completely and bake as directed below.
• Substitute almond flour for all-purpose flour to make this gluten-free.
