The Essential Ingredients for This Gourmet Sandwich
This iconic dish uses a handful of simple, high-quality ingredients to create its signature bold and savory flavor.
- The Bread:
- Sourdough Bread: The sturdy structure and signature, tangy flavor of a good quality sourdough bread is the absolute perfect choice to stand up to the rich, bold flavors of the fillings without becoming soggy.
- The Cheesy Spread: This is the secret to a perfectly creamy and tangy sandwich.
- Blue Cheese: The star of the show! Use your favorite variety of crumbled blue cheese. A creamy, milder Gorgonzola Dolce is a great choice, while a sharp and pungent Stilton or a Danish Blue will provide a bolder, funkier flavor.
- Cream Cheese: It is crucial to use softened, room temperature cream cheese. Mixing the potent blue cheese with the mild cream cheese is the secret that tames its sharp bite and creates a spread that is perfectly creamy, wonderfully tangy, and melts beautifully.
- The Roast Beef: Using a high-quality, thinly sliced deli roast beef is a fantastic and convenient shortcut. Look for a rare or medium-rare roast beef for the most tender and flavorful result.

Step-by-Step to the Perfect Grilled Cheese
This delicious meal comes together in just a few simple stages.
Step 1: Make the Creamy Blue Cheese Spread and Assemble
Step 1: In a small bowl, use a fork or a small spatula to mix together the 2 ounces of softened cream cheese and the 2 ounces of crumbled blue cheese until they are well blended into a creamy spread.
Step 2: Spread the blue cheese mixture evenly over one side of all 8 slices of your sourdough bread.
Step 3: On 4 of the bread slices, layer your 3/4 pound of thinly sliced deli roast beef and your 1/2 of a thinly sliced small red onion.
Step 4: Top with the remaining 4 slices of bread, with the cheese-spread side facing down.
Part 2: Grill to Golden, Melty Perfection
Step 1: Brush the outsides (the top and the bottom) of each of your assembled sandwiches with the 1/4 cup of olive oil.
Pro Tip: For an even richer, more perfectly golden-brown crust, you can spread a thin layer of mayonnaise on the outside of the bread instead of the olive oil. The oil in the mayonnaise has a high smoke point and is a fantastic secret for the best grilled cheese crust!
Step 2: In a large skillet or on a griddle, toast the sandwiches over a medium heat.
Pro Tip (The Secret to a Perfect Grilled Cheese!): It is crucial to cook your grilled cheese over a gentle, medium or medium-low heat. This “low and slow” method is the secret that gives the cheese in the center plenty of time to melt completely and become gooey, while the bread on the outside has time to slowly toast to a perfect, even, deep golden brown without burning.
Step 3: Cook the sandwiches for 4 to 5 minutes on each side, until the bread is golden brown and crispy and the cheese is completely melted.
Slice the sandwiches in half and serve them immediately while they are hot and gooey.

The Ultimate Grilled Roast Beef and Blue Cheese Sandwich
A simple yet elegant recipe for a gourmet grilled beef and blue cheese sandwich. The sandwich features a creamy spread made from a blend of softened cream cheese and crumbled blue cheese on sourdough bread. It is then layered with thinly sliced deli roast beef and red onion. The outside of the sandwich is brushed with olive oil and toasted in a skillet over medium heat until the bread is golden brown and the cheesy filling is melted and warm.
Ingredients
- 2 ounces cream cheese, softened
- 2 ounces crumbled blue cheese
- 8 slices sourdough bread
- 3/4 pound thinly sliced deli roast beef
- 1/2 small red onion, thinly sliced
- 1/4 cup olive oil
Instructions
- In a small bowl, mix the softened cream cheese and crumbled blue cheese until they are blended into a spread.
- Spread the cheese mixture over all 8 slices of sourdough bread.
- Layer the roast beef and sliced red onion on 4 of the bread slices.
- Top with the remaining 4 bread slices, cheese-side down, to complete the sandwiches.
- Brush the outsides of the sandwiches with olive oil.
- In a large skillet, toast the sandwiches over medium heat for 4-5 minutes on each side, until the bread is golden brown and the cheese is melted.
- Slice in half and serve immediately.
Notes
- Using softened cream cheese is a key step that allows it to blend easily with the blue cheese to create a smooth spread.
- This recipe uses olive oil instead of butter for grilling, which provides a nice flavor and helps to crisp the bread.
- Cooking the sandwiches over medium heat ensures the cheese melts completely by the time the bread is perfectly toasted.
What to Serve With Your Grilled Beef & Blue Cheese Sandwich
This beautiful and rich sandwich is a fantastic meal on its own. To round it out, here are a few simple and classic pairings:
- A Classic Soup: The absolute perfect partner for any grilled cheese! This bold sandwich is fantastic with a simple, creamy tomato soup or a rich and savory French onion soup.
- A Simple Green Salad: A crisp green salad, especially one with a bright and zesty balsamic vinaigrette, is the perfect, fresh counterpoint to the rich, cheesy sandwich.
- Kettle-Cooked Potato Chips: A simple side of your favorite crunchy, kettle-cooked potato chips and a crisp pickle spear is another classic and easy choice.
Storage and Make-Ahead Tips
A grilled cheese sandwich is at its absolute crispiest and best when it is served fresh and hot from the skillet.
- Make-Ahead: For a super-fast and impressive lunch or dinner, you can prepare the creamy blue cheese spread up to 5 days in advance. Store it in an airtight container in the refrigerator. This makes the final assembly of the sandwiches incredibly fast.
- Storage: Store any leftover grilled cheese, well-wrapped, in the refrigerator for up to 3 days.
- Reheating: The best way to reheat a grilled cheese and bring back its original crispy texture is in a dry skillet on the stovetop over a low heat, or in an air fryer at 350°F for just 2-3 minutes.

Creative Recipe Variations
- Add a Sweet & Savory Jam: For a delicious, gourmet contrast, you can spread a very thin layer of fig jam or an onion bacon jam on the inside of the bread along with the blue cheese spread.
- Add Some Peppery Greens: For a fresh, peppery bite that is a classic pairing with beef and blue cheese, you can add a small handful of fresh baby arugula to the inside of your sandwich before you grill it.
- Use a Different Meat or Cheese: If you’re not a fan of roast beef, this sandwich is also absolutely fantastic with thinly sliced deli turkey or ham. If you don’t like blue cheese, a sharp provolone or a white cheddar would also be delicious.

Frequently Asked Questions (FAQs)
Q1: What is the absolute secret to a crispy, not soggy, and perfectly golden-brown grilled cheese?
There are two main secrets! First, be sure to use a good, sturdy bread like a sourdough. Second, and most importantly, is to cook it low and slow. A gentle, medium-low heat is the key that allows the cheese to fully melt while the bread toasts to a perfect, even golden brown without burning.
Q2: What is the best bread to use for a gourmet grilled cheese?
A bread with a sturdy structure and a good, robust flavor is the best choice to stand up to hearty fillings. A classic, tangy sourdough is a fantastic choice, as are a rustic ciabatta or a thick-sliced multigrain bread.
Q3: What is the best way to melt the cheese all the way through without burning the bread?
Again, the secret is a medium-low heat. Another great trick is to place a lid over your skillet for the first few minutes of cooking. This will trap the steam and the heat, which will help the cheese to melt much more quickly and evenly.
Q4: Can I make the blue cheese spread ahead of time?
Yes, absolutely! The creamy blue cheese spread is a perfect make-ahead component. You can prepare it completely and store it in an airtight container in the refrigerator for up to 5 days. This makes the final assembly for a quick lunch incredibly fast.
Q5: What is the best kind of blue cheese to use for this recipe?
This recipe is wonderfully versatile! For a milder, creamier flavor, a classic Italian Gorgonzola Dolce is a fantastic choice. For a much sharper, tangier, and more pungent flavor, you could use an English Stilton or a French Roquefort
