Rainbow sandwiches recipe

I made rainbow grilled cheese sandwiches for my oldest kid when she was about 3 years old and it has been a requested favorite ever since. I don’t do them often, but when I do you know it’s a special occasion.

Often referred to as “unicorn grilled cheese” in this house, the colors vary but often carry that fun rainbow vibe.

These sandwiches are baked, making them even easier for feeding a big family. With the stovetop method, I often found myself taking 5 minutes per sandwich, but I can make 6-8 of them in under 10 minutes with this nifty trick!

Tips for making rainbow cheese

When I make oven baked sandwiches I choose to spray the outside of my sandwiches with Canola, Olive oil or a butter spray instead of spreading softened butter on them. This helps to get a nice golden color and crisp bread. It sounds weird, but it works great and keeps you from over buttering the bread and getting a soggy sandwich.

Also, adding the cheese seems to be as much fun as eating it! *So says my kids.

FAQs about Rainbow Toasties

What kind of cheese should I use?

You can use any white or lighter colored shreddable cheese. I personally prefer mozzarella, Italian blend, Pizza blend, or white cheddar. But Muenster gives a great stringy cheese if you’re looking for that coolness factor when you bite into the rainbow cheese!

What type of bread should I use?

You can use any type of bread! I usually grab whatever’s on hand (which is usually plain white or wheat sandwich bread). But honey oat, buttermilk bread, 12 grain, etc. They all work. So use what you like. 😉

Where did rainbow grilled cheeses come from?

This trend has been going on for almost a decade now (that I’m personally aware of). With a lot of the original inspiration for rainbow toasties coming from South Korea, Australia, and other parts of the world. Some are served with sprinkles on the bread and others include fun colored bread too. But the basic idea of colored cheese and bread remains the same everywhere (can’t have a grilled cheese without them).

How to make rainbow sandwiches

Preheat your oven to 450F degrees. On a baking sheet arrange your bottom bread slices.

Butter the tops of the bread slices or spray with cooking spray. Flip over so that it’s “wet” side is facing the pan.

In small bowls or zipper topped bags, divide your cheese and add a few drops of color. About 2-5 is plenty, the more you add the more vibrant the color. Mix until the cheese is completely colored.

Arrange your cheese on the prepared bread slices that are on the baking sheet.

Add the top slice of bread and butter or spray the tops.

Bake for 5 minutes, flip over and then bake for another 3-5 minutes.
