Instructions

1. Cook the macaroni
Bring water and 1 teaspoon salt to a boil in a medium saucepan. Add macaroni and cook until just al dente, about 7–8 minutes. Drain well.
2. Make the cheese sauce
In the same saucepan, melt 2 tablespoons butter over medium heat. Stir in the drained macaroni, milk, shredded cheddar cheese, and black pepper. Stir until cheese is fully melted and the sauce is creamy. Remove from heat. Let cool slightly so it thickens.
3. Assemble the sandwiches
Lay out the bread slices on a clean surface. Spread softened butter on one side of each slice.
4. Fill the bread
On the unbuttered side of 4 slices, mound about 1/4 cup of macaroni and cheese. Top with a slice of cheddar or American cheese, if using. Cover with the remaining bread slices, buttered side out.
5. Cook the sandwiches
Heat a large skillet or griddle over medium heat. Place sandwiches in the pan (work in batches if needed). Cook 3–4 minutes per side, pressing gently with a spatula, until bread is golden and crisp and cheese is melted.
6. Rest and serve
Remove from the skillet, let rest 1–2 minutes, then slice and serve hot.

Zusatztipps für die Zubereitung

To ensure the sandwich holds together, let the macaroni and cheese cool slightly before assembling; this allows the cheese sauce to thicken and act as a glue. Using a sturdy bread like sourdough helps support the weight of the pasta filling while providing a beautiful golden-brown crust.

Varianten und Anpassungen

Customize your sandwich by mixing a tablespoon of chopped chives or crispy bacon bits into the macaroni before assembly. For those who enjoy a bit of heat or tang, try adding a sprinkle of hot sauce or a thin slice of fresh tomato inside the sandwich before grilling.

Serviervorschläge

For the ultimate nostalgic meal, serve your Mac & Cheese Grilled Cheese with a side of hot tomato soup for dipping. It also pairs wonderfully with a simple green salad or a few pickles to cut through the richness of the cheese.

Recipe Questions

Can I use leftover macaroni and cheese?

Absolutely. Leftover macaroni and cheese works perfectly for this sandwich. Simply spread it between buttered bread slices and griddle as directed. If it's very thick, you can warm it slightly to make spreading easier.

What bread works best?

Sourdough and dense sandwich breads hold up well to griddling and creamy fillings. Brioche, Texas toast, or thick-cut white bread are excellent alternatives that become beautifully golden when buttered and toasted.

How do I prevent the filling from leaking?

Allow the macaroni and cheese to cool slightly after cooking so it thickens and holds together better. Don't overfill each sandwich. Press gently with a spatula while cooking rather than applying heavy pressure.

Can I make these ahead?

Prepare the macaroni and cheese up to two days ahead and refrigerate. Assemble sandwiches shortly before cooking for best results, as buttered bread can get soggy if assembled too far in advance.

What temperature should the skillet be?

Medium heat is ideal. Too high and the bread burns before the cheese melts inside. Medium heat allows 3-4 minutes per side for the bread to turn golden while the filling becomes warm and gooey.

How can I add more flavor?

Mix crispy bacon, sautéed mushrooms, or fresh chives into the macaroni and cheese. Add sliced tomato, caramelized onions, or a dash of hot sauce to individual sandwiches for personalized variations.

Sandwich

01 8 slices sourdough or sandwich bread
02 4 tablespoons unsalted butter, softened
03 1 cup prepared macaroni and cheese
04 4 slices cheddar or American cheese, optional

Directions

Step 01

Prepare the Macaroni: Bring 2 cups of water and 1 teaspoon salt to a boil in a medium saucepan. Add 1 cup elbow macaroni and cook until just al dente, approximately 7-8 minutes. Drain thoroughly using a colander.

Step 02

Create the Cheese Sauce: In the same saucepan, melt 2 tablespoons butter over medium heat. Stir in the drained macaroni, 1/2 cup whole milk, 1 1/2 cups shredded cheddar cheese, and 1/4 teaspoon ground black pepper. Continue stirring until cheese is fully melted and sauce reaches a creamy consistency. Remove from heat and allow to cool slightly to achieve desired thickness.

Step 03

Assemble the Sandwiches: Lay out all 8 bread slices on a clean work surface. Spread softened butter on one side of each slice. On the unbuttered side of 4 slices, distribute approximately 1/4 cup macaroni and cheese mixture. Top with one slice of cheddar or American cheese if desired. Cover with remaining bread slices, ensuring buttered sides face outward.

Step 04

Toast the Sandwiches: Heat a large skillet or griddle to medium heat. Place sandwiches in the pan, working in batches if necessary. Cook 3-4 minutes per side, gently pressing with a spatula, until bread is golden and crispy and cheese is fully melted.

Step 05

Rest and Serve: Remove sandwiches from skillet and allow to rest 1-2 minutes. Slice diagonally and serve immediately while hot.
