I’m going to start right off the bat by saying that I totally get if you aren’t sure about green mac and cheese. But hear me out.

Back when I was a brand new blogger, plenty of my early readers were not sure about spinach in muffins. But I did it anyway and I won MANY hearts (and tastebuds) over and made veggie-loaded believers out of them with my oh-so popular Green Smoothie Muffins. So, I want you to trust me here because I think this Spinach Mac and Cheese is the lunch or dinner version of those beloved muffins.

Why?

Because while Spinach Mac and Cheese is oh-so-green in color, it has the familiar flavor and texture of good ‘ol homemade mac and cheese. There are no leaves of wilted spinach in the mix, as the spinach has been combined into the cheese sauce to make the spinach texture and flavor literally blend in. Plus, it is easy to make (almost as easy and time friendly as boxed) in about 15 minutes, so it is a great option for when you want something simple, delicious, and that gets some veggies in. Bonus: you can make it with either fresh or frozen spinach! A cozy, one pot recipe that is vegetarian, can easily be gluten free and helps your family see that green veggies can be tasty…..what more could you want?

What kind of pasta should I use for this green mac and cheese?

You can make this with any kind of pasta you want—whole wheat, gluten free, or bean-based. Just make sure to cook according to the package instructions.

My family really doesn’t like spinach. How can I make this work for them?

Do you have a child or any family member that might be iffy about to trying green mac and cheese? Start with half (or even less) of the amount of spinach and then work your way up to using more.

Can I make this mac and cheese ahead of time?

Absolutely. Just reheat and eat. I find the microwave heats it up perfectly.

Can I use kale instead of spinach?

I love that spinach is delicate and just blends so easily into the cheese sauce of this recipe. Kale is a much more fibrous veggie and, while it can be used in place of spinach, might give the green mac and cheese a different, maybe grittier, texture.

Suggested Adaptations

  • Want to add more veggies? Frozen broccoli, peas, and green beans are all easy additions. Just add them to the pasta during the last minute of cook time, drain, and add to the sauce with the pasta.
  • Adjust the amount of spinach to fit your needs. Start with half the amount of spinach and then work your way up to using more if you feel that will be best for you and/or your family. Or, add more spinach if you are super jazzed about really green mac and cheese.
  • Add more cheese. If you like a super cheesy mac and cheese, toss in more grated cheddar to make this veggie-loaded meal something you will love a little extra.
  • Make it gluten free with your favorite small gluten free pasta.
