Recipe: Grilled Cheese Sandwich with Mustard

A good grilled cheese sandwich is comfort food at its best. It works on its own but is also perfect alongside a bowl of tomato soup. The traditional version is just bread and cheese, but I sometimes add mustard because I like the extra flavor it brings. I usually make mine with Gruyère or cheddar, but for the photos for this recipe, my dad suggested I use a couple of slices of his extra-aged Danbo, which had been stinking up my parents’ fridge. It melted just fine, but the flavor was way too strong for me.

In the US, American cheese or cheddar is probably the most classic choice for a grilled cheese, but Monterey Jack, Provolone, or Gruyère are also excellent options. If you’re in the mood to experiment, try mixing two different cheeses, for example cheddar and Monterey Jack, for both flavor and creaminess.

I like sourdough bread because it stays crisp, has a bit of chew, and that slight tang that pairs so well with cheese and mustard. A thin layer of Dijon adds heat and depth, though whole-grain mustard works too if you want more texture and a milder taste.

Ingredients

  • 2 slices sourdough bread

  • 1-2 tablespoons Dijon mustard (or whole-grain mustard)

  • 2-3 slices cheese (cheddar, Emmental, Havarti, Monterey Jack, Provolone, or Gruyère)

  • Butter

Directions

  • Spread a thin layer of butter on one side of each bread slice.
  • Flip one slice over and spread the other side with mustard.
  • Add the cheese, then top with the second slice of bread, buttered side facing out.
  • Cook the sandwich in a skillet over medium heat, a couple of minutes on each side, until the bread is golden and crisp and the cheese has melted. You can cover the pan with a lid so the heat circulates and the cheese melts evenly without the bread browning too quickly.
  • Let the sandwich rest on a cutting board for a minute before slicing it in half.
Le Creuset Enameled Cast Iron Signature Iron Handle Skillet, Caribbean
$219.95

If there’s one piece of cookware that can take your everyday cooking to the next level, it’s a good cast iron skillet. I’m especially smitten with the Le Creuset Enameled Cast Iron Signature Skillet in Caribbean. The color alone makes me want to keep it out on the counter, but it’s the performance that really makes it shine.

Enameled cast iron heats evenly and holds onto that heat, which means perfectly seared steaks, golden grilled cheese, and veggies that cook through without burning. Unlike traditional cast iron, it doesn’t need seasoning, so it’s ready to use right away. The enamel interior is durable and easy to clean, while the skillet itself is lighter than most cast iron of the same size, making it easier to handle. It also works on any cooktop, slides into the oven up to 500°F, and even goes in the dishwasher.

Caraway Nonstick Ceramic Frying Pan (2.7 qt, 10.5")
$115.00

Caraway recently launched on Amazon, and their cookware is as pretty as it is practical. The Caraway 10.5" Nonstick Ceramic Frying Pan is one of those pieces you’ll find yourself reaching for all the time, whether it’s for eggs, sautéed veggies, or pancakes on the weekend. I especially love it in Perracotta, which adds such a nice pop of color in the kitchen.

The naturally non-stick surface means you can cook with less oil or butter, and cleanup is quick with just a wipe or light wash. Like all of Caraway’s cookware, the pan is free from PTFE, PFOA, PFAS, lead, and cadmium, so you don’t have to worry about toxins sneaking into your food.

It works on all stovetops, gas, electric, and induction, and it’s oven-safe up to 550ºF, which makes it super versatile. Durable, easy to use, and so good-looking, this is a pan that really makes everyday cooking feel a little more special.
