Preheat the oven to 400 degrees. Set out an 11” oven safe casserole dish. Grease the bottom of the dish with butter or spray if desired. In my enamel pan, greasing is unnecessary.
Prep the potatoes. Use a mandoline to slice the potatoes thin, up to ¼” thick. You can slice them all the same thickness, or vary the thickness like I do in the recipe video. It doesn’t really matter, but sometimes I change it up. In the video, the bottom layer of potatoes is ¼” thick and the top layer of potatoes are sliced paper-thin. Either way, it will bake just fine.
Add a layer of half the potatoes to the casserole dish. You can do a mix of both yellow and sweet potatoes, or do one type of potato in this bottom layer, the other type on top. Again, it doesn’t matter - whatever you’re in the mood for!
Add a layer of half the mixed frozen vegetables.
Add the rest of the potatoes, without overflowing the casserole dish.
Add the rest of the mixed frozen vegetables.
Whisk together the milk, flour, and pesto. Pour the pesto milk mixture over the potatoes, sweet potatoes, and frozen veggies, without overflowing the casserole dish.
Top with cheddar cheese and bake in the oven, covered with foil for 30 minutes, then with foil removed for another 20-30 minutes until potatoes are easily pierced with a fork.

Notes
Use 1" diced frozen vegetables. It’s best to use frozen vegetables that are diced in 1” segments. I used a variety of corn, peas, peppers and carrots. You can throw in some fresh veggies the same size or substitute them in this recipe as well.
Make frozen mixed vegetables potatoes au gratin ahead. This is the perfect meal prep dinner! Simply construct and layer your potatoes au gratin with frozen vegetables, refrigerate or freeze, then pop into the oven when you're ready to eat. Super simple prep, super simple clean up, super successful family dinner.
Don't forget the leftovers. This easy weeknight dinner recipe tastes just as good the next day! Refrigerate your leftovers for 3-4 days and reheat throughout the week for a quick work from home lunch.
Feeding a crowd. This recipe can be easily doubled or tripled depending on the number of people you are feeding. Remember not to overstuff your baking dish, though! I would recommend making multiples instead of trying to make one huge casserole.
