Potato Spinach and Tomato Gratin – a delicious, cheesy gratin made with sliced potatoes, fresh spinach, and tomatoes. Great weeknight side dish.

If you’re like me, sometimes the hardest part of meal planning is coming up with interesting side dishes. I can get the entree – no problem! – but the sides sometimes stump me. Especially if you’re serving little ones whose faces don’t always brighten at the prospect of “eating their vegetables.”

Even with the pickiest eaters, the one side you can almost always depend on is potatoes isn’t it? Really, how many people do you know who don’t like potatoes? I can’t think of one.

I was very pleased to be offered an opportunity to create this recipe using Simply Potatoes brand products. They’re one of my go-to grocery items and I’ve been using them for quite a long time. They’re fresh potato products, never frozen, that you’ll find in your grocery store’s dairy section. And the very best thing? The prep is already done for you! No peeling, slicing, or shredding required. That can be a real plus for a busy household!

I use Simply Potatoes for lots of recipes from breakfast to brunch to dinner. Some of our favorites are the hash browns which make frequent appearances on our weekend breakfast table and the mashed sweet potatoes that I often serve with pork chops or roasted chicken.

For this recipe, I used the Simply Potatoes Homestyle Slices layered with fresh spinach, tomatoes, and cheddar cheese to make a very kid-friendly side dish. With all that cheese and potatoes, the kids will hardly know you sneaked in a whole bunch of nutritious spinach :-)

How to Make Potato Spinach and Tomato Gratin

Preheat the oven to 350 degrees.

Slice the tomatoes into approximately 1/4” slices. I strongly recommend using Roma tomatoes for this recipe. They typically have fewer seeds and less juice than other tomatoes. They’ll help keep your gratin from becoming watery.

Chopped green onions on a cutting board.

Chop the green onions using all the white and the tender green parts.

Baking dish with drizzled olive oil in the bottom.

Drizzle half the olive oil in a baking dish or gratin dish.

Sliced potatoes in bottom of a baking dish.

Place half the potato slices in an even layer in the dish. Lightly sprinkle with salt and pepper.

Half the tomato slices layered over the potato slices.

Layer half the tomato slices. Sprinkle with half the oregano and lightly salt and pepper each slice.

Potato and tomato slices topped with green onions in a baking dish.

Layer half the green onions over the tomatoes.

A layer of spinach added to the baking dish.

Make a layer with the spinach. Lightly sprinkle with salt and pepper.

Half the grated cheese layered over the spinach in the baking dish.

Cover evenly with half the grated cheddar cheese.

Finished layering of vegetables in the baking dish.

Repeat making layers with remaining ingredients. (Note: you’ll use all the spinach in its one layer so your final layers will be potatoes (seasoned), tomatoes (seasoned), onions, cheese.) Drizzle top with remaining olive oil.

Cover with foil and bake for 40 minutes.

When the baking time is nearly complete, grate the fresh Parmesan. Remove the foil and top with the grated Parmesan cheese. Return the dish to the oven and bake for an additional 10 minutes.

Allow to cool for 5-10 minutes before serving.
