    Published: May 18, 2023 · Modified: Dec 18, 2024 by tomatoestomahtos · This post may contain affiliate links ·

    I think everyone gets really excited to have a dairy meal on Shavuos since Yom Tov meals are always meat! It's hard to make a balanced meal and not just stuff in a million delicious carb filled dairy delicacies. I figured we all could use something green to add to the table, but of course still filled with creamy goodness like melted cheese and heavy cream. Easy creamed spinach gratin (with frozen spinach) it's so simple to make, and pairs beautifully with anything from penne alla vodka to salmon.

    What you need for easy creamed spinach gratin (with frozen spinach)

    • Butter
    • Onion
    • Garlic
    • Flour
    • Heavy cream
    • Milk
    • Shredded mozzarella cheese
    • Frozen spinach
    • Salt and Pepper
    • Panko crumbs
    • Parmesan cheese

    How to make it:

    1. Prepping the spinach: Start by preparing the frozen spinach. If you planned in advance and it's already defosted, simply put it in a heavy duty paper towel or kitchen towel and squeeze out any remaining liquid. Transfer to a bowl for later use. If your spinach is still frozen, you can microwave it and stir at 1 minute intervals until it's defrosted. This can take up to around 8 minutes sometimes. Continue with squeezing out the excess water with the method above.
    2. Make the sauce: melt the butter in a large pot. Remove 1 tablespoon of the butter and set it aside for the topping. Sautee the onion then add the garlic and flour. Stir for 1 minute, until the flour taste cooks out. Add in the cream, milk and cheese and whisk until you have a silky smooth creamy sauce. Pour in the spinach, salt, and pepper and mix well.
    3. Assemble: Pour the mixture into a greased baking dish. Combine the 1 tablespoon of butter with the panko and parmesan. Mix together and top the gratin.
    4. Bake: Bake for around 30 minutes, until the gratin is golden brown on top and bubbling around the edges. Let it cool for 5 minutes before serving.

    • ¼ cup all-purpose flour

    • Transfer the mixture to a greased baking dish. Combine the melted butter set aside earlier with the panko and parmesan to form a topping. Sprinkle it over the gratin.
    • Bake for 30 minutes until the cheese is golden and the mixture is bubbly. Cool for 5 minutes before serving.
