Copycat Zupas Grilled Cheese Recipe

There are certain restaurant dishes that live in your memory long after the meal is over. For me, the Ultimate Grilled Cheese from Zupas is one of those dishes. I remember the first time I tried it; I was expecting a simple, comforting sandwich, but what I got was a culinary revelation. The combination of perfectly melted, gooey cheeses, the savory-herbal punch of pesto, and the tangy, crusty sourdough bread was nothing short of extraordinary. It was rich, decadent, and yet perfectly balanced. After ordering it more times than I care to admit, I knew I had a mission: to recreate that exact experience in my own kitchen. The first time I served my copycat version to my family, the silence was immediate, broken only by the crunch of the bread and a few appreciative “mmms.” My kids, who thought grilled cheese was just yellow cheese between white bread, looked at me like I was a magician. This recipe isn’t just a sandwich; it’s an event. It’s the perfect centerpiece for a cozy weeknight dinner, a guaranteed crowd-pleaser for a casual get-together, and my personal go-to for a little dose of culinary self-care. Now, I’m sharing the secrets so you can bring this little piece of restaurant magic home.

The Ultimate Copycat Zupas Grilled Cheese Recipe

This recipe meticulously breaks down the components that make the Zupas Ultimate Grilled Cheese so iconic. The key is in the quality of the ingredients and the specific combination of cheeses that deliver both a superior melt and a complex flavor profile. The homemade pesto aioli is the secret weapon that elevates this from a simple sandwich to a gourmet experience.

Ingredients You’ll Need

For the Pesto Aioli:

• ½ cup Mayonnaise (high-quality, full-fat for best results)
• ¼ cup Prepared Basil Pesto (store-bought or homemade)
• 1 clove Garlic, minced (or ¼ teaspoon garlic powder)
• 1 tablespoon Lemon Juice, freshly squeezed
• Pinch of Salt and Black Pepper

For the Grilled Cheese Sandwich (makes 2 sandwiches):

• 4 slices Sourdough Bread, sliced about ½-inch thick
• 4 tablespoons Unsalted Butter, softened to room temperature
• 4 slices Muenster Cheese (about 4 ounces)
• 4 slices Provolone Cheese (about 4 ounces)
• 2 tablespoons Grated Parmesan Cheese (optional, for an extra crispy crust)

Step-by-Step Instructions to Grilled Cheese Perfection

Follow these instructions carefully to replicate the texture and flavor of the original Zupas masterpiece. The process is simple, but the technique, especially regarding heat management, is crucial for success.

Step 1: Prepare the Pesto Aioli

The first step is to create the vibrant, flavorful spread that forms the heart of this sandwich.

1. In a small bowl, combine the mayonnaise, prepared basil pesto, minced garlic, and fresh lemon juice.
2. Whisk the ingredients together until they are smooth and uniformly green. The mixture should be creamy and easily spreadable.
3. Taste the aioli and season with a pinch of salt and freshly ground black pepper as needed. The pesto itself is salty, so be careful not to over-season.
4. Set the pesto aioli aside. This can be made up to three days in advance and stored in an airtight container in the refrigerator. Allowing it to sit for at least 30 minutes before use helps the flavors meld together.

Step 2: Assemble the Sandwich

Proper assembly is key to ensuring every bite has the perfect ratio of bread, cheese, and aioli.

1. Lay out the four slices of sourdough bread on a clean work surface or cutting board.
2. Using a butter knife or small spatula, generously spread the softened unsalted butter on one side of each of the four bread slices. Go all the way to the edges to ensure the entire surface gets crispy and golden.
3. If you’re using the optional grated Parmesan for an extra-crispy, cheesy crust, lightly sprinkle it over the buttered sides of the bread and gently press it in so it adheres.
4. Flip two of the bread slices over (buttered-side down). These will be the bottom halves of your sandwiches.
5. On the unbuttered side of these two slices, spread a generous layer of the prepared pesto aioli. Don’t be shy; this is where a huge amount of flavor comes from.
6. Now, layer the cheese. Place two slices of Muenster cheese on top of the pesto aioli, covering the surface of the bread.
7. Follow with two slices of Provolone cheese on top of the Muenster. Layering the cheeses ensures a complex flavor and an epic “cheese pull.”
8. Take the remaining two slices of bread and spread pesto aioli on their unbuttered sides. Place them, aioli-side down, on top of the cheese to complete the sandwiches. You should now have two fully assembled sandwiches with butter (and possibly Parmesan) on the outside.

Step 3: Achieve the Golden-Brown Crust

This is the most critical stage. The goal is a deeply golden, crunchy exterior while the interior cheese begins to melt. Low and slow is the mantra here.

1. Place a large non-stick skillet, cast-iron pan, or griddle over low to medium-low heat. It’s crucial not to start with high heat, as this will burn the bread before the cheese has a chance to melt.
2. Once the pan is gently heated, carefully place the assembled sandwiches in the skillet. You should hear a very gentle sizzle, not a loud crackle.
3. Cook for 4-6 minutes on the first side. Resist the urge to press down on the sandwich with your spatula, as this can compact the bread and squeeze out the cheese. Let the gentle heat do the work. You can check the underside after about 3 minutes; it should be turning a light golden brown.
4. Using a wide spatula, carefully flip the sandwiches over. The cooked side should be a beautiful, crisp golden-brown.
5. Cook for another 4-6 minutes on the second side until it matches the first.

Step 4: The Final Melt and Serve

If your cheese isn’t fully melted by the time the bread is perfectly toasted, use this simple trick.

1. Reduce the heat to the lowest possible setting.
2. Cover the skillet with a lid for 1-2 minutes. This traps steam and heat, creating a small oven-like environment that will melt the cheese into a gooey, molten river without burning the bread.
3. Once the cheese is fully melted and oozing from the sides, remove the sandwiches from the skillet and place them on a cutting board.
4. Let the grilled cheese rest for one minute before slicing. This allows the cheese to set slightly, preventing it from all spilling out when you cut into it.
5. Slice the sandwiches in half diagonally and serve immediately while hot and gooey.

How to Serve Your Zupas-Style Grilled Cheese

While this sandwich is a star on its own, pairing it with the right accompaniments can elevate your meal from great to unforgettable. Here’s how to serve it for the ultimate Zupas experience at home.

• The Classic Soup Companion:
  • Creamy Tomato Basil Soup: The absolute quintessential pairing. The acidity and sweetness of the tomato soup cut through the richness of the cheesy sandwich, creating a perfect flavor harmony.
  • Roasted Red Pepper and Smoked Gouda Soup: For an even more complex and smoky flavor profile that complements the provolone and pesto.
  • Hearty Vegetable Soup: A chunky vegetable soup provides a lighter, healthier contrast to the decadent grilled cheese.
• Creative Dipping Sauces:
  • Extra Pesto Aioli: Serve a small ramekin of the aioli on the side for extra dipping.
  • Classic Marinara Sauce: Dipping the grilled cheese in a warm marinara sauce gives it a pizza-like flavor that is incredibly satisfying.
  • Balsamic Glaze: A drizzle of thick, sweet balsamic glaze over the top or on the side for dipping adds a sophisticated sweet-and-sour element.
  • Hot Honey: For a trendy and delicious twist, a drizzle of hot honey provides a sweet and spicy kick that pairs surprisingly well with the savory cheeses.
• Salads and Sides:
  • Simple Arugula Salad: A light salad of arugula tossed with lemon vinaigrette, shaved Parmesan, and toasted pine nuts offers a peppery and acidic counterpoint.
  • Crisp Dill Pickles: A crunchy, briny pickle spear is a classic sandwich sidekick that cleanses the palate between rich, cheesy bites.
  • Kettle-Cooked Potato Chips: For that perfect crunch factor, a side of high-quality, kettle-cooked sea salt chips is a simple but effective choice.
  • Fresh Fruit: A small bowl of grapes, apple slices, or melon provides a fresh, sweet, and juicy contrast to the heavy sandwich.

5 Pro-Tips for an Even More Ultimate Grilled Cheese

Take your sandwich-making skills to the next level with these expert tips designed to guarantee a perfect result every single time.

1. The Bread is Your Foundation
The choice of bread is arguably as important as the cheese. While this recipe calls for sourdough for its tangy flavor and sturdy crumb that holds up to the fillings, don’t be afraid to experiment. A thick-cut Brioche will lend a richer, sweeter, and more cake-like texture. Challah offers a similar richness. A rustic Italian or country loaf also works beautifully. The key is to choose a bread that is sturdy enough to contain the molten cheese and has a structure that will toast well.

2. The Cheese is Queen (Let it Shine)
For the best possible cheese pull, the type and preparation of the cheese matter. While pre-sliced cheese is convenient, buying a block and slicing it yourself often results in a better melt, as pre-sliced varieties can have anti-caking agents. For an even faster and more uniform melt, shred your cheese from a block. Also, allow your cheese to come to room temperature for about 15-20 minutes before assembling the sandwich. Cold cheese takes much longer to melt, increasing the risk of burning your bread.

3. The Great Butter vs. Mayo Debate
This recipe uses classic butter for its unparalleled flavor. However, many grilled cheese aficionados swear by mayonnaise. Spreading a thin layer of mayonnaise on the outside of the bread instead of butter yields an incredibly crisp, golden-brown crust that’s less prone to burning. Why? Mayo is essentially an emulsion of oil and eggs. The oil has a higher smoke point than butter, and the sugars and proteins in the egg contribute to faster, more even browning. For the best of both worlds, try a mixture of softened butter and a dollop of mayo.

4. Embrace the Low and Slow Philosophy
Patience is the secret ingredient to a perfect grilled cheese. A common mistake is cranking the heat up to high in an attempt to speed up the process. This inevitably leads to a tragic outcome: burnt, blackened bread and a solid, un-melted block of cheese in the center. By cooking on low to medium-low heat, you give the heat time to penetrate through the bread and gently warm the cheese, melting it slowly and evenly while the exterior develops a flawless, crunchy, golden crust.

5. Get Creative with Customizations
While this copycat recipe aims for authenticity, your kitchen has no rules. Use this recipe as a base and make it your own.

• Add Protein: A few slices of crispy prosciutto, cooked bacon, or thinly sliced turkey would be delicious additions.
• Introduce Veggies: A layer of sweet caramelized onions, sautéed mushrooms, or a few slices of fresh, juicy tomato (pat it dry first!) can add another dimension of flavor and texture.
• Spice it Up: Add a pinch of red pepper flakes to the pesto aioli or a few pickled jalapeños inside the sandwich for a spicy kick.

Frequently Asked Questions (FAQ)

Here are answers to some of the most common questions about making the perfect Copycat Zupas Ultimate Grilled Cheese.

1. Can I use different cheeses if I can’t find Muenster or Provolone?
Absolutely! The Muenster/Provolone combination is chosen for its perfect balance of meltiness (Muenster) and savory flavor (Provolone). However, you can easily substitute with other great melting cheeses. Good alternatives include Gruyère (for a nutty, complex flavor), Fontina (creamy and mild), or even a combination of white cheddar and mozzarella for that classic flavor and epic cheese pull.

2. How do I get my cheese to melt perfectly without burning the bread?
This is the ultimate grilled cheese challenge, and the solution is two-fold: low heat and a lid. Cook the sandwich on a consistent low to medium-low heat. This ensures the bread toasts slowly, allowing the heat to reach the cheese. If your bread is perfectly golden but the cheese isn’t quite there yet, turn the heat to its lowest setting and cover the pan with a lid for a minute or two. This traps steam and creates an oven-like effect, melting the cheese to gooey perfection.

3. Can I make this recipe gluten-free?
Yes, you can easily adapt this recipe to be gluten-free. Simply substitute the sourdough bread with your favorite brand of high-quality, thick-sliced gluten-free bread. Gluten-free breads tend to be a bit more delicate and can sometimes brown faster, so keep a close eye on it and stick to the low-heat cooking method. All other ingredients in the recipe are naturally gluten-free, but always double-check the labels on your pesto and cheeses to be certain.

4. What’s the best way to store and reheat leftovers?
While a grilled cheese is undeniably best when eaten fresh, you can store leftovers. Wrap the cooled sandwich tightly in aluminum foil and refrigerate for up to two days. The microwave is the enemy of leftover grilled cheese—it will make the bread steamy and soggy. The best way to reheat it is in a dry, non-stick skillet over low heat for a few minutes per side until the bread is re-crisped and the cheese is re-melted. Alternatively, an air fryer at 350°F (175°C) for 3-5 minutes works wonders to bring it back to life.

5. Can I make these grilled cheese sandwiches for a crowd?
Yes, but cooking them one or two at a time in a skillet can be slow. The best method for serving a crowd is to use an oven. Assemble all the sandwiches as directed. Place them on a large baking sheet. Bake in a preheated oven at 425°F (220°C) for about 5 minutes, then carefully flip them and bake for another 3-5 minutes, or until both sides are golden brown and the cheese is fully melted. This method ensures everyone gets a hot, crispy sandwich at the same time.
