MY LATEST RECIPES

I have a weird thing about yellow cheeses, so I chose my absolute favorite, Gruyere.  Of course I had to add some extra cheeses, so I also went with a bit of white cheddar and one thin slice of Muenster 🙂  If you’d prefer a different cheese blend, by all means, go for it!

The hardest thing about this gourmet grilled cheese, is maybe fitting into your pants after you’re done… because you won’t be able to have just one sandwich!

While I think a great sandwich is good all on it’s own… sometimes you just need something to dip it in.  I highly recommend my Slow Cooker Creamy Tomato Basil Soup!

If you really want to kick this gourmet grilled cheese up a notch or two… add some prosciutto slices or crispy bacon.  Talk about pure heaven!!

This gourmet grilled cheese is loaded with herbed caramelized onions, gooey gruyere and white cheddar cheeses, and is cooked in a savory rosemary butter!
Author: The Chunky Chef
Ingredients
  • 8 slices good quality bread I used thick cut Artisan bread
  • Mayonnaise for spreading
  • 12 oz Gruyere cheese sliced thinly OR grated, at room temperature
  • 6 oz White cheddar cheese sliced thinly OR grated, at room temperature
  • 4 slices thin Muenster cheese at room temperature
  • 2 yellow onions diced
  • 1 tsp fresh thyme minced
  • 2 tsp fresh rosemary minced, divided
  • 1 tsp brown sugar
  • Salt and pepper to taste
  • 3 Tbsp butter divided
  • 1 Tbsp olive oil
Instructions
  1. Add 1 1/2 Tbsp butter and olive oil to a skillet and heat over MED-LOW heat. Add diced onions, salt, pepper, fresh thyme and 1 tsp of fresh rosemary to the hot skillet and saute, stirring often, until onions are soft and starting to brown, about 10 minutes.
  2. Stir brown sugar into the onions and cook another minute.
  3. Transfer onions to a plate.
  4. Spread one side of two pieces of bread with a little bit of mayonnaise.
  5. To the same skillet, add remaining butter and rosemary, and heat over MED heat. Swirl to coat the bottom of the skillet with the melted butter.
  6. Add both pieces of bread, mayonnaise side down, and cook until bread is golden brown and crunchy, about 2-3 minutes.
  7. As soon as you add the bread to the skillet, add a bit of cheese to the top of each piece of bread. Once it starts to melt a little, sprinkle a couple tablespoons of the caramelized onions over the top of one of the pieces of bread.
  8. When the bread is good and golden brown, sandwich the pieces of bread together and cook on LOW until cheese is fully melted.
  9. Transfer to a plate, repeat with remaining slices of bread and ingredients.
  10. Slice and enjoy!
Recipe Notes

1. If you're having trouble getting your cheese to melt, add all the cheese to a food processor and pulse until they form a paste. Use as directed.

  1. This is so good!  We’ll be making it again…and again…and again 😋

  2. Amanda….this sandwhich was simply amazing!! I made it for my boyfriend last night. He and I were both VERY impressed!! Keep up the delicious work babe!!

  3. This is a great recipe.  The whole family loved it.  It’s making my 7-year-old reconsidering his distaste for onions (he didn’t believe me.  I had to open his and show him).  I even took a leftover half to work for lunch the next day.  I microwaved it, it was chewy, and yet… somehow still delicious.  I just wanted to thank you for sharing.  It’s the best grilled cheese I’ve ever eaten, and I made it myself!  Definitely going in the recipe journal.

    Thanks again,
    Em

  4. Hi, this is Emalee-Makenzy Pressley or Emmy. Can I use cheddar cheese? My kids Olivia and Oliver prefer that cheese. I also love this recipe because when Ollie goes to dance, I can make this and she eats in in the car. I used to put leftovers in the microwave or buy fast food. We fell in love with this recipe. Please reply. This recipe is just….. YUM!!

    • Hi Emmy 🙂 I’m so glad you all love this recipe!! Yes, cheddar cheese can totally be substituted… it may taste a little different (but still good!), and not have the same gooey stretch the other cheeses have, but it’s a great option 🙂

  6. I made this tonight and it was REALLY good! I left out the onions though (even though I love onions). I used a garlic loaf artisan bread and it worked perfectly. I didn’t have any rosemary on hand but I think that would have definitely been a nice touch. I paired with your slow cooker creamy tomato soup. My husband and I both loved it!

  7. HOLA ES MUY importante poder saber como se traducen tus recetas al español

    • Hi there 🙂 Less than half of 1 percent of the web traffic that comes to this blog is from a Spanish speaking person, and unfortunately, I can’t write this to appease every single person that comes to my site. I write for the majority. Google translate is a wonderful free feature, where you can copy and paste and it will translate it for you.

  8. Spot on! I substituted the cheese suggested, since, limited cheese type available in my area and uh-la-la.. look exactly the same in the picture and taste P.E.R.F.E.C.T . Absolutely lovin it in every bite and crust. Thank you for sharing… No more searching for grill cheese outside. Pullstop.

  9. Holy moly. Looks and sounds so delicious! I am jealous!

  10. This sounds like a great sandwich… rosemary and Gruyere sounds amazing! It’s one of my favorite cheeses too, there’s a local spot that makes a burger stuffed with it and it’s awesome.

  11. Tried these awesome Gourmet Grilled Cheese Sammies tonight with a side of your yumm-O tomato basil soup! So simple, but my husband loved them (yes, he had two) and our friends raved over them! Thank you so much for your inspiration! Next weekend, I’m going to try the bourbon glazed wings. I don’t normally keep buttermilk in the house, but it’s on my shopping list for this week. My kids love pretty much anything, so I figure this one’s going to be a keeper too! Thanks Amanda, for all of your wonderful recipes!

  12. I know what is for lunch this weekend! Yum!!!

  13. That gooey cheese and caramelized onion…a match made in heaven!

  14. Whoa — just look at all of that cheese! My husband is a grilled cheese junkie, and he would love this!

  15. Oh my goodness! This is probably the best looking grilled cheese sandwich I’ve ever seen! You’re honestly killing me with your gorgeous photos!

  16. That cheese ?? You have mastered the gooey cheesy photos!

  17. This is basically the most perfect grilled cheese ever!!

  18. Nothing better than a gourmet grilled cheese!

  19. Oh my gosh! You weren’t kidding when you said “ultimate”! This is basically my dream grilled cheese, can’t wait to try it out! 🙂

  20. Rosemary butter!? Are you kidding me?! This sounds absolutely amazing!!

  21. Rosemary, caramelized onions and cheese? I’m in! What a ridiculously delicious flavor combo!

  22. I would say that’s a gourmet sammie! My pants got tired just reading it!
