    These easy baked rainbow grilled cheese sandwiches are super easy to make and even more fun to eat! My kids love them, and I'm sure yours will too!

    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.

    This rainbow sandwich recipe is often referred to as "unicorn grilled cheese" in this house. The colors vary but often carry that fun rainbow vibe.

    For more grilled cheese recipes, check out my Microwave Grilled Cheese, Sheet Pan Grilled Cheese Sandwiches, and Air Fryer Grilled Ham and Cheese.

    Why This Recipe Works

    1. Multiple sandwiches at once. These sandwiches are baked, making them even easier to feed 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!
    2. They're easy to make. Shred some cheese and mix with colors. This recipe is simple and easy to make. I often have my kids help with mixing the colors and adding the cheese to the sandwiches.
    3. They're fun! Anyone can make a grilled cheese sandwich, but making them into a fun lunch that the kids get excited about eating is something not everyone can do. You're going to love watching their eyes light up.

    labeled ingredients needed to make this recipe

    🥘 Ingredients

    Shredded white cheese- You can use mozzarella cheese or white American cheese. Even muster works well if you can find it in brick form.

    Sandwich bread- Use your favorite sliced sandwich bread.

    Butter- You will need some non-stick cooking spray or softened butter to coat the outside of the bread. This helps make them taste richer and makes them golden and crispy too!

    Food coloring- Use some food coloring in rainbow colors to give your cheese that fun color. I prefer gel food coloring because it's more vibrant.

    For the exact amounts needed, please see the recipe card below.

    • Baking Sheet
    • Spatula (for flipping the sandwiches over)
    • Small Bowls or plastic baggies

    🔪 Instructions

    Check out how to make rainbow sandwiches with these simple step-by-step instructions:

    Preheat your oven to 450F degrees.

    6 slices of sandwich bread on baking sheet

    On a baking sheet, arrange your bottom bread slices.

    buttered bread on baking sheet

    Butter the tops of the bread slices or spray with cooking spray. Flip over so that its "wet" side is facing the pan.

    divided white shredded cheese in bags with dots of food coloring in each

    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.

    divided bags of shredded colored cheeses

    Mix until the cheese is completely colored.

    🍴 Recipe Tips

    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 crispy 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

    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). A lot of the original inspiration for rainbow toasties came 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 grilled cheese without them).
