Sneak some spinach into your mashed potatoes in with these cheesy Spinach Mashed Potatoes. Even though the mashed potatoes have green in them, the kids love them!

Have you ever sneaked veggies in food? I have. And I’ll be honest. Most of the time I’m found out. There’s been a few times when I’ve sneaked pureed squash into lasagna or spaghetti sauce and added cauliflower to a casserole. Green vegetables, though? That’s a little harder. I don’t know about your kids (or husband!), but mine can spy a green speck in food from a mile away.

This Spinach Mashed Potatoes recipe is one that has green spinach inside but is so delicious. Creamy, cheesy and full of mashed potato flavor. You’ll hardly even taste the spinach.

Why you’ll love this recipe:

Butter, sour cream, salt and cheese gave the potatoes an amazing flavor.
This recipe makes a full 9×13 pan of mashed potatoes. It’s a great potluck side dish and is easily portable.
Leftovers are delicious too.
A potato side dish that goes with just about any main dish.

What is the best potato for mashed potato?

There are so many varieties of potatoes, sometime is is hard to know which potatoes are best for salads, mashing or roasting. Mashed potatoes are best made with a high starch potato such as a Russet. They stay light and fluffy during mashing.

If you can’t get your hands on Russet potatoes, round white potatoes, a medium starch potato, is second best.

What to add to mashed potatoes:

Other than potatoes, there are a few key ingredients that give these potatoes flavor:

Sour cream. Sour cream is often served with baked potatoes, so why not mix it into mashed potatoes? It adds to the creaminess, but also adds flavor.
Butter. Butter always adds a rich smoothness to baked goods. Butter deepens the flavor.
Salt & Pepper. And maybe a little garlic if you’d like.
Spinach. As I said earlier, spinach doesn’t add a ton of flavor, but it adds lots of vitamins and minerals.
Cheddar Cheese. Don’t you love cheese topped casseroles? Especially when it gets just a little crispy on the edges. Mmmm…so good.

How to Make Spinach Mashed Potatoes

Prepare the potatoes. Peel the potatoes and cut them into chunks. Boil them in a large pot of water until the potatoes are soft.
Thaw the spinach. While the potatoes are cooking, place the thawed spinach in a strainer to drain as much water off as possible.
Preheat the oven to 400º Fahrenheit. Spray a 9×13 baking pan with cooking spray.
Assemble the potatoes. Drain the water off the potatoes and mash the potatoes. Add the sour cream, salt, and pepper to the potatoes. Beat the potato mixture until it is fluffy. Stir the drained spinach into the mashed potatoes.
Bake. Spread the mixture in the prepared pan. Sprinkle the shredded cheese on top of the mashed potatoes. Bake for 25-30 minutes, or until it is bubbly and the cheese is melted.
