Substitutions and Variations
Macaroni and Cheese Substitutions
- Pasta: Swap elbow macaroni with shells, cavatappi, or penne for a different bite.
- Milk: Replace with half-and-half for extra creaminess or use unsweetened oat/almond milk for a lighter option.
- Mozzarella: Use sharp cheddar, gouda, or fontina for a stronger, richer flavor.
- Oregano: Trade for Italian seasoning, dried basil, or smoked paprika for a flavor twist.
- Salt: Add garlic salt or onion powder for an extra savory kick.
Grilled Cheese Substitutions
- Bread: Replace marble rye with sourdough, brioche, or whole wheat for different textures and flavors.
- Monterey Jack: Swap for pepper jack (spicy), provolone (mild), or Swiss (nutty).
- Butter: Use mayonnaise on the bread exterior for an ultra-crispy crust.
Variations
- Bacon Lovers: Add crispy bacon inside the sandwich for a smoky crunch.
- Veggie Twist: Layer in roasted red peppers, caramelized onions, or sautéed mushrooms.
- Spicy Kick: Mix sriracha or hot sauce into the mac n cheese before assembling.
- Tex-Mex Style: Add taco seasoning to the cheese sauce and use pepper jack cheese.
- BBQ Version: Spread a little BBQ sauce on the bread before grilling for sweet-savory depth.
- Extra Cheesy: Use three cheeses (cheddar, mozzarella, and parmesan) in the mac for maximum gooeyness.
How to make Mac n Cheese Grilled Cheese
- Bring a large pot of water to a boil and cook the macaroni noodles until al dente or as directed on the packaging. Drain once cooked.
- Melt, in a large skillet on medium heat, the butter. Whisk in the flour until smooth. Let simmer for 30 seconds until lightly golden with a nutty aroma. This is called a "roux" and what will thicken the cheese sauce.
- Slowly pour the milk into the roux, a little at a time while whisking, letting it return to a smooth consistency after each addition.
- Bring the sauce back to a simmer and whisk in the grated cheese. Add the salt and dry oregano. Once the sauce is smooth, turn off the heat.
5. Add the cooked macaroni into the cheese sauce. Stir until fully incorporated. Let the mac n cheese rest for 5-10 minutes to lightly thicken.
6. Use a griddle or large frying pan to cook the grilled cheeses. Butter the outside of the bread slices and place butter side down on the grill. Place a slice of cheese on each piece of bread and pile on the mac n cheese on half of them. Once the bread is golden, flip the slices over the ones with the macaroni to create the sandwiches.
Storage
Store cooled Mac n Cheese Grilled Cheeses in an airtight container in the refrigerator for up to 3 days. Separate each sandwich with parchment paper to prevent sticking. Reheat in a skillet or air fryer until warmed through and crisp again—avoid the microwave, as it can make the bread soggy. For longer storage, wrap tightly in foil, place in a freezer-safe bag, and freeze for up to 1 month.
