    This Corned Beef Grilled Cheese is the ultimate St. Patrick's Day sandwich, made with buttery toasted bread, caramelized onions, melted cheese, and corned beef. Simple, flavorful, delicious!

    This recipe creates a tasty and filling sandwich recipe, but if you're still in the mood to try even more sandwich recipes, then try making a Toasted Steak Sandwich or a cheesy Croque Monsieur.

    Of course, you don’t really need a recipe for a grilled cheese sandwich, but I have to share this combination because not only is it delicious but it also contains corned beef, Swiss cheese, and caramelized onions on buttery toasted rye bread.

    A grilled cheese sandwich is the one thing that I love making on those evenings when I don't feel like spending much time in the kitchen. It's also the perfect thing to whip up when you don't feel like leaving the house to make a trip to the grocery store because you probably already have the main ingredients in your kitchen and that is bread and cheese.

    The bread for this sandwich that I am going to use is some seeded rye bread that I was able to pick up in the bakery section of my grocery store. I love using bread from there because it's fresh and contains simple ingredients with fewer preservatives. For the cheese, I will be using some slices of Swiss cheese, but if you are able to find Jarlsberg cheese that would be amazing as well.

    Now if you have some corned beef that you've already prepared to celebrate St. Patrick’s Day with, then feel free to slice that and use it instead, but if you don't then just grab some deli slices of corned beef and cut it into strips to add to the caramelized onions that you will sauté prior to assembling the corned beef grilled cheese.

    This recipe makes enough for two grilled cheese sandwiches, so you can eat one and share the other. If you need more than two, then feel free to double or triple the recipe!

    Let's get started.

    Ingredient Notes

    ingredients needed to make sandwich in separate small bowls and a plate on marble surface
    1. Deli-sliced corned beef - Try selecting thinly sliced or shredded corned beef from the deli counter. You will need at least two ounces to make two sandwiches.
    2. Swiss cheese - To make this grilled cheese sandwich we are going to use Swiss cheese, but Jarlsberg cheese will pair well with the corned beef if that is available.
    3. Bread - For this recipe I will be using seeded rye bread, but feel free to use any bread that you prefer.
    4. Butter - You may use salted or unsalted depending on your preference.
    5. Onion - Any white or yellow onion will do.
    6. Worcestershire sauce - Adds amazing flavor to the sandwich.
    7. Mustard - Try using a grainy mustard.
    8. Sugar - Only need a small amount of granulated or can sugar.
    9. Salt - This will help to season the onions.
    10. Ground black pepper - Adds additional flavor to the onion while cooking.

    Instructions

    Begin the recipe using a large skillet over medium-high heat. Once warm, add the butter and allow it to melt before adding in the onion, sugar, salt, and ground black pepper. Cook the onion mixture stirring regularly until the onions are soft, translucent, and golden brown. About 10 to 15 minutes.

    Carefully remove the skillet from the heat and stir in the corned beef, Worcestershire sauce, and mustard until combined. Set aside for a moment while you complete the next step.

    Using four slices of bread, top each with a slice of cheese.  Next, divide the corned beef mixture in half and place the mixture evenly on top of two slices of bread over the cheese. Cover the corned beef mixture with the other two slices of bread to create two sandwiches. 

    Using the same large skillet, return it to the stove over medium-high heat. Once warm, add the butter and allow it to melt before adding the sandwiches. If the skillet is not large enough to hold them both at the same time, then divide the butter in half and cook one at a time.

    Once the bread has toasted on one side, use a spatula to flip to the other side and press the sandwich down using the spatula as it cooks. Once the bread is toasted and the cheese has melted, carefully removed the sandwiches from the skillet. Serve warm and enjoy!

      Goodness! I just sent this link to Cassidy. I really think it's brilliant. We don't have mustard but I think we have everything else so that's just one quick grab at the store.
