    French Onion Grilled Cheese

    Caramelized sweet Vidalia onions mixed with rich Gruyère cheese and melted between a thick sliced crusty bread makes the perfect French Onion Grilled Cheese.

    For today’s post I have Partnered with Sara Lee, but as always, all opinions are my own. Grilled cheese is America’s favorite sandwich, but taking it to the next level is a meal solution that everyone will love. Grilled cheeses are always popular on Domestic Superhero; Caprese Grilled Cheese, Spinach Pesto Grilled Cheese, and BBQ Chicken & Pineapple Grilled Cheese are just a few of the popular recipes I’ve shared. However, this French Onion Grilled Cheese is going to blow your mind! It’s ooey-gooey, and majorly delicious! 

    Today I’m sharing a locally inspired French Onion Grilled Cheese. Why is it locally inspired? Because I am from Georgia, and I am featuring Georgia’s delicious Vidalia onions! They are the perfect onion for French onion soup, grilled cheese, or anything! It’s EASY to make this French Onion Grilled Cheese!

    How to make French Onion Grilled Cheese:

    **scroll down for full ingredient list and printable directions**

    • Get all of the ingredients together: Vidalia onions, gruyere cheese, Sara Lee® Artesano™ Bread, butter, salt, and pepper.
      • I love using Sara Lee Artesano Bread because it’s the ORIGINAL artisan-style sliced bread. Sliced thick with a mouthwateringly soft texture and rich flavor plus: No high fructose corn syrup, no artificial flavors, and no artificial colors!
    •  

    • Heat a heavy bottom skillet over medium low heat and add the butter to the skillet. While it’s melting, slice the onions thinly.
      • Add the onions to the skillet once the butter is melted, and then sauté them for a few minutes.
      • Turn the heat to low/medium and let the onions sit.
        • You are going to caramelize the onions and this takes some time…about 20-25 minutes. Let the onions sit in the skillet and stir them every 5-6 minutes. Once the onions are browned and soft they are good to go!

    • Next you will add the cooked onions to the grated cheese.
      • I like mixing the cheese and onions before adding to the bread because it ensures equal distribution of the cheese and onions for every bite!

    • Next, take the softened butter and slather onto one side of each slice of bread (this will be the side you cook the sandwich on). Then, add the onion mixture on the side of the bread that does not have the butter, and add another slice to the top, butter facing out. 
    • Wipe out the skillet you cooked the onions in, then heat over low/medium heat. Place the grilled cheese into the skillet, butter facing down. Cook 3-4 minutes or until browned on that side, then carefully flip over. Cook 2-3 minutes on the other side and remove from the pan. Cook the second French onion grilled cheese. 

    • EAT while HOT!

    Tips for making the perfect grilled cheese:

    • Keep the skillet over a medium/low heat. It is very easy to burn the bread while cooking a grilled cheese, so avoid this by cooking over medium/low heat. This ensures the cheese melts while not cooking the bread too quickly.
    • Use enough cheese! Grilled cheese is meant to be packed with cheese…don’t skimp!
    • Eat right after it’s cooked! No one likes soggy or cold hardened grilled cheese! Eat it freshly cooked for the most outstanding taste!

    This is the perfect time of the year to make delicious hearty grilled cheese sandwiches! Make sure to use Sara Lee Artesano Bread for the best possible grilled cheese!
