What to serve with this potato zucchini casserole bake?

How to make Zucchini and Potato Casserole

Preheat oven to 375 degrees. Wrap your 4-5 whole garlic cloves in foil. Roast for about 25 minutes until tender. Remove roasted garlic from skin and smash.
In a medium bowl, combine 2 cups heavy cream, 1/2 cup Parmesan cheese and 1/2 cup shredded monterey jack cheese, roasted garlic, and a 1/2 teaspoon of oregano, salt and pepper.
Thinly slice 4-5 small potatoes. You’ll want the potatoes to be about 4 times thinner than the zucchini, or about 1/16 of an inch. Slice 2 medium zucchinis, about 1/4 of an inch. Quarter 2 small onions and slice thinly.
Layer the zucchini, potatoes, and onions in a casserole dish or 4 individual casserole dishes. You’ll have more potatoes than the others, so I layer like this: 2 potatoes overlapping, zucchini, onion, and repeat.
Pour the cream mixture over the veggies, about 1/2 cup per individual dish or evenly over a larger baking dish. Top with remaining cheeses.
Bake at 400 degrees for about 30 (individual) to 45 minutes. Garnish with chopped parsley.

Can I make this casserole ahead of time?

I wouldn’t suggest pre-assembling the casserole. The potatoes and zucchini are likely to release liquid as it sits, especially if salted, causing it to be runny. It’s best to bake as soon as it’s ready to go.
