Prepare your casserole dish (spray pam, oil or butter it) and start layering.
-
21
Preheat oven to 350
-
22
You can layer any way you want.
-
23
What I did is I started with rows of potatoes overlapping each other till the casserole dish was filled.
-
24
Topped it with rows or a layer of zucchini and then a layer of yellow squash.
-
25
At this step you can put half of the onion-milk mixture over the vegetables and then continue doing another layer of potatoes, zucchini and squash.
-
26
Top with the last of the onion-milk mixture.
-
27
Cover it with foil and bake for 35 min at 350.

While it's cooking prepare the breadcrumb topping.
-
29
Put your breadcrumbs and italian seasoning in a bowl, top with oil and stir.
-

If using fresh breadcrumbs, get 2 slices of bread and squish it and roll it in your hands until it forms a ball and throw it in your blender.
-
31
Blend for a few seconds until you get breadcrumb consistency.
-
32
Remove pan from oven, remove foil and sprinkle breadcrumbs over the casserole and then sprinkle your cheese over the breadcrumbs.
-
33
Add more or less breadcrumbs as needed.
-
34
Place.
-
35
uncovered casserole back in oven and bake for another 15 to 20 minutes.
-
36
*Tips* Instead of cornstarch you can make a roux using 2 tbsp flour and 2 tbsp butter.
-
37
Put this in the pan before the milk.
-

Stirring and cooking the flour till it changes color then add the milk.
