Best Bread for Grilled Cheese:

This is such an easy and budget-friendly dish, that I pretty much use whatever bread I have available. However, for best results, you should look for sturdy enough bread to hold the cheese in.

White bread and sourdough are pretty popular to make this recipe. Also, if you like darker bread, then go with dark rye. It is widely available, and it has a nice and distinctive aroma that perfectly complements the cheese. 

What is the Best Cheese for Grilled Cheese?

Like in the case with bread, you can pretty much use any type you have on hand, or love best. For a classic grilled cheese, go with American.

For a more distinctive and rich flavor, I recommend using sharp cheddar, or provolone cheese. Also, Colby, Monterey Jack, Gouda, and Blue cheese are perfectly fine here. So, go with what you like the most. 

How to Make French Dip Grilled Cheese Sandwich?

For exact directions and ingredient measures, please see the recipe card below. But the general steps are as follows:

  1. Prepare the sauce: This French onion dipping sauce is unbelievably delicious, and it is what makes this sandwich stand apart. In an iron cast skillet, prepare the sauce. Once done, set it aside.  
  2. Toast the bread: I recommend roasting the bread over low heat. This way, the bread will get a nice golden brown color and become super crunchy. 
  3. Add the cheese and roast beef: Once the bread is nicely toasted, add the cheese, meat, and caramelized onion. Then, top it with the remaining slices of bread. It really doesn’t matter what cheese you use as long as its one you love and don’t skimp on it!

Tips and Tricks to make the perfect French Dip Grilled Sandwich:

  • I like to use deli roast beef as its quick and easy. You can also use any leftover shredded beef, like from cooking a beef chuck roast.
  • Also, feel free to use a mixture of various cheeses as well. It works perfectly fine, and it gives the sandwich an even better flavor. 
  • If the pan is too hot, the cheese won’t melt before the outside is cooked. In addition, if you see that the cheese is not melting for a while, then cover it with a lid. The steam will help melt the cheese so it cooks evenly!
  • Don’t skip the caramelized onions, they make a huge difference in this sandwich!!
  • Most groceries stored carry Au Jus Mix, just look in the seasoning aisle.
  • I used store-bought french fried onions, you can make yours if you want.
  • The french fried onions are optional, you can serve them on the side or add some to your sandwich for a nice crunch.
  • Butter the bread and cook the sandwiches in a cast iron or on the griddle.
  • Serve the sandwiches immediately.

Tools/Ingredients I use to make this recipe:

  • Cast Iron Skillet – get one and you will use it forever. I like that it heats evenly and consistently and that it comes pre-seasoned for the first use.
  • Tongs – I like the locking functionality on these, they are the best on the market.

    This looks like a great recipe, but with such good ingredients, why in the world would you use regular old white bread??? There are tons of other great options with more character and more nutrition ! Does not compute in my “world of cooking.”

    • Catalina Castravet

      Linda, darling, thank you so much for checking the recipe šŸ™‚ I LOVE good, old white bread as it does not compete with the flavors šŸ™‚ BUT you can use ANY bread that you love šŸ™‚ to make the sandwich even better šŸ™‚

  • monika

    Why do you keep calling everything “french” in this recipe?
    THere is nothing inherently french about it…
    SO confused!
    (Is it because the sauce its reminiscent of “french” onion soup?)

    • Catalina Castravet

      I am probably more confused than you, I don’t think I am calling everything “french” except the dip. hm.

    • GrammaSue

      Monika, why must people be so “literal” in their reviews. “French” Dip anything is a colloquialism. Since she created the recipe, she can call it what she wants. Why not just say if you like it or not instead of being so persnickie…

      • Catalina Castravet

        Thank you very much šŸ™‚ sometimes I don’t get why people feel the need to criticize something that doesn’t need to be criticized.

  • Rosein

    I’m a little confused as well. Perhaps you are unfamiliar with french dip sandwiches? This recipe is a variation of a french dip sandwich, hence the name. And, no, it’s not really french, any more than french fries are. However, it is the name of the sandwich, so it makes sense to use it. I only see the word “french” in the recipe in regards to the dip, so your claim of”why do you keep calling everything ‘french’ in this recipe” is a bit strange.

    • Catalina Castravet

      I think you answered your own questions when you said: “This recipe is a variation of a french dip sandwich, hence the name.” hm….

  • GrammaSue

    This sounds like a great combination. As far as the THE WHITE BREAD goes, when its all combined, who can tell the difference with so many flavors going on. If you just want to not feel guilty, then by all means, use a healthier choice. If you don’t care and want to save money, use the white bread…. all tastes the same in this incident. Great recipe idea and thank you!

  • Jeanne

    I’ve been making a variation of this for a while now. One of my favorites when I don’t want to put a lot of thought or time, but still want a great meal. Great to see other people like French Dips this way. My only change up is that I use the instructions from the Mousetrap (http://www.cookingchanneltv.com/recipes/mousetrap-2010682) to cook the sandwich. Easy and you can cook more than one at time. And sourdough bread. šŸ˜‰

  • Merie Surkan

    Made it…Big hit here. I used shaved leftover roast beef from Sunday dinner of which I had saved the roasting juices. I just thickened some juice a little with a tsp of cornstarch instead of buying the package mix. We used sharp cheddar and gouda and homemade whole wheat bread. What a filling sandwich! I think 1/2 sandwich would have been enough for me. Definitely a keeper recipe!

  • Angie

    Making tonite šŸ˜‹ I can’t wait..I made roast yesterday and saved the broth. I am gonna use leftovers, make the sauce with the leftover broth..i bet it will be a ton of flavors…thank you for the recipe now roast beef leftovers won’t go to waste
