This is not your average casserole! Bright yellow squash blends beautifully with added veggies and cheeses to make a hearty dish that will delight at holidays, summer gatherings, or any occasion.
In a large pot, boil squash quarters until tender, drain well and set aside.
In a large mixing bowl, blend together cheeses. Add whisked eggs, chopped onion and bell pepper, drained squash, and remaining ingredients. Stir well to combine.
Pour squash mixture into greased casserole dish and bake for 30 to 45 minutes, or until cooked through and light golden brown.
Notes
Optional Topping: If you would like a crunchy topping, you can add Ritz cracker crumbs over the casserole prior to baking.
