Happy National Grilled Cheese Month! YES. There is a whole month dedicated to the deliciousness that is grilled cheese. Gosh I love food holidays. Not that I need a green light to indulge in one of my favorite foods, but I’ll take the excuse anytime!

In celebration of this fantastic holiday I’ve teamed up with Sara Lee Bread to bring you the best darn grilled cheese sandwich you could dream of. I’ve been eating Sara Lee breads for years, first for my pb+j sandwiches (I never grew out of them), then I stumbled across their and have been using it for homemade French toast ever since (THE BEST!).

Now that I’ve tried it for grilled cheese, I’m more in love than ever.

Stack it high with Swiss, provolone, and parmesan cheeses and caramelized onions and a second slice of bread. Grill it in a skillet or on a griddle until browned on both sides and cheese is ooey gooey melted perfection.

Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Servings: 2 servings


  • 4 slices Sara Lee Artesano Bread
  • 2 tablespoons butter, softened
  • 2 tablespoons mayo
  • 1/2 teaspoon dijon mustard
  • 4 slices Swiss cheese
  • 4 slices provolone cheese
  • 1/3 cup freshly grated parmesan cheese
  • 1/2 yellow onion thinly sliced
  • 2 cups beef broth
  • salt and pepper to taste
  • 1 tablespoon flour
  • 2 tablespoons water


  • Add onion slices and 1 cup of beef broth to a large skillet and bring to a boil over high heat. Continue to simmer until liquid is gone and onions are browned. While liquid is reducing, move on to the next step. 
  • Butter one side of four slices of bread. Flip bread over. Stir together mayo and dijon mustard and spread on second side of all four slices of bread. Top two slices of bread each with two slices of Swiss cheese, two slices of provolone, and half of the parmesan cheese. 
  • One beef broth is fully reduced and onions are browned, remove onions from skillet, divide in half, and place on top of the cheeses. Top with a second slice of bread (mayo side down/facing the cheese and onions) and place in a second skillet over medium-low heat or a griddle set to medium-low. 
  • While sandwiches are cooking, pour remaining 1 cup beef broth into the skillet you used for the onions. Bring to a boil. Stir together water and flour and gradually whisk into the boiling beef broth until thickened. Season with salt and pepper to taste, then remove from heat. 
  • Once the bottom of the sandwiches are browned, flip and brown for another 3-4 minutes until cheeses are melted and second side is browned. Slice in half and serve with the gravy for dipping.

Oh my how fabulous! Please share this with the Food on Friday crowd over at Carole’s Chatter. Cheers


    So happy to hear this, Patty! They changed my view point of a grilled cheese from then on! 😉

4 stars
I made these last night with swiss and old cheddar. the onions really made a difference. i would argue that you don’t need the gravy as the onions make the sandwich so savoury

    Thanks for your feedback, Heather! I am excited to hear that you enjoyed this recipe! 🙂
