Kid Friendly
These are easy to make and a very kid friendly recipe. Children might need a little help with the actual grilling, and grating. But there's plenty of food coloring drops to add, stirring, piling of cheese, and buttering to keep kids busy with this easy rainbow grilled cheese recipe.
Ingredients:
- Food Colouring -We created our colors of the rainbow using white cheese and food dye. If you're uncomfortable using food dyes, there are natural food colorings available at specialty shops. We used inexpensive liquid food coloring for ours. You could also use gel food coloring for this recipe. Use the primary colors and mix them for the secondary colors. If you want darker colors, just add more drops of food coloring.
- Cheese -We mainly used mozzarella cheese. It's a great cheese for this because it's white so it takes the dye easily, it's inexpensive, and it has a mild taste, which tends to appeal to kids. It's also a great melter, and has a really good cheese pull factor, meaning you'll get those lovely stringy bits when you pull the cheese apart. We also added in a little Swiss cheese, for flavour, but also for an increased cheese pull factor.
Tip: The thick cheese layers really add to the rainbow factor. With a good amount of cheese, you'll be able to see each colour well, and get a great cheese pull when you pull your sliced sandwich apart.
- Bread -A good crusty white bread works great for this sandwich. We sliced ours quite thickly, which worked great with a thick layer of cheese. The thick cheese layers really add to the rainbow factor. With a good amount of cheese, you'll be able to see each colour well, and get a great cheese pull when you pull your sliced sandwich apart.
Variations
You could also try using white cheddar, havarti, or provolone, or any combination of these and the mozzarella and Swiss cheese for different flavors.
Regular sandwich bread is a great and easy option for the bread.
Gluten Free: If you want to make your rainbow grilled cheese gluten free, you can substitute gluten free bread for this recipe.
Instructions
1. Begin by grating your cheese. Place shredded cheese into 6 different bowls. Use all mozzarella cheese, or mix in a few some Swiss cheese, or any other cheese you prefer.
2. Dye the cheese by adding around drops of food colouring to a bowl and stirring the bowl of cheese until it's fully combined and the cheese is coloured. To create the orange cheese use drops of red, and yellow food colouring. To make the purple cheese, use red and blue food colouring.
3. Next, butter the outside of each of the bread slices. Lay out the bottom two pieces of bread, butter side down, and arrange the cheese on top of the unbuttered side. Create six equal lines of coloured cheese in a rainbow pattern, in rainbow order: red, orange, yellow, green, blue, and purple. Divide the cheese evenly between the two cheese sandwiches. Then place the top slice of bread on each of the sandwiches, buttered sides out.
4. Place the sandwiches in a frying pan, and cook over medium heat. Flip the sandwiches when the first side is golden brown, and cook the other side to golden bread as well. You may want to put a lid on the frying pan, as an easy way to help the cheese melt well.
5. To serve your sandwich, make sure to cut the sandwich in half, in the opposite direction that your cheese is running so that when you pull it apart you have the rainbow effect with the melted cheese.
Storage
Your rainbow grilled cheese is best eaten as soon as it's made. If you making your rainbow grilled cheese for a party and want to dye your cheese ahead of time you can make it the day before and store it in a sealed container in the refrigerator, then cook the sandwiches right before serving.
Tip: Use a lid on your frying pan to help the cheese melt. This traps the warm air, and with a thick layer of cheese like we used on this sandwich, really helps to make sure all the cheese is nice and melted.
