Step‑by‑Step Instructions for Ultimate Pesto and Cheese Open-Faced Sandwich
Step 1: Prepare the Pesto
In a food processor, combine fresh basil leaves, toasted pine nuts, and roughly chopped garlic cloves. Add a pinch of sea salt and freshly cracked black pepper to enhance flavors. Then, stream in high-quality olive oil while blending until the mixture is well combined but still has texture. Finally, add grated Parmesan cheese and pulse until you achieve a smooth, creamy pesto. This aromatic blend is the foundation for your Baguette Sandwich.
Step 2: Assemble the Sandwich
Preheat your oven’s broiler while you prepare the baguette. Slice it in half lengthwise to create two sturdy bases for your open-faced sandwich. Generously spread the vibrant pesto you just made on each half, ensuring an even layer. Next, arrange halved cherry tomatoes on top, followed by a hearty helping of shredded sharp cheddar cheese, allowing its creamy flavor to harmonize with the pesto.
Step 3: Broil the Sandwich
Place the assembled baguette halves on a baking sheet and slide them under the broiler. Keep a close eye on them as they broil for about 3 to 5 minutes, or until the cheese is melted, bubbly, and just starting to turn golden brown. This quick process transforms your sandwich into a gooey, cheesy masterpiece, melding all the wonderful flavors together.
Step 4: Serve and Enjoy
Once the cheddar cheese has reached a delightful gooeyness with a hint of golden brown, carefully remove your Baguette Sandwich from the oven. Let it cool for a minute, then serve warm, either directly in hand or elegantly on a plate. Take a moment to appreciate the crispy baguette, the melted cheese, and the fresh toppings, ready to satisfy your cravings for this delicious comfort food.

Make Ahead Options
These Baguette Sandwiches are perfect for meal prep enthusiasts! You can prepare the pesto up to 3 days in advance; simply store it in an airtight container in the refrigerator to preserve its vibrant flavor. The baguette can be sliced and wrapped tightly in plastic wrap to keep it fresh for up to 24 hours. When you’re ready to enjoy your sandwich, spread the prepped pesto on the sliced baguette, layer with cherry tomatoes and cheese, and broil until the cheese is gooey and bubbly. This way, you’ll have a delicious and comforting meal ready with just a few finishing steps, making busy weeknights so much easier!

Ultimate Pesto and Cheese Open-Faced Sandwich Recipe FAQs
How do I know if my basil is fresh enough for the pesto?
Absolutely! When selecting fresh basil leaves, look for vibrant green color, tender leaves without dark spots or yellowing. They should have a fragrant aroma. Avoid any that are wilted or have significant discoloration, as these signs indicate age.
What’s the best way to store leftover baguette sandwiches?
Very! Store your leftover baguette sandwich in an airtight container in the fridge for up to 1 day. This helps retain moisture without making the bread too soggy. If you want to keep it crispy, you can wrap it tightly in foil but don’t add any toppings until you’re ready to eat.
Can I freeze the pesto used for this sandwich?
Absolutely! To freeze your homemade pesto, place it in an ice cube tray for easy portioning. Once frozen, transfer the cubes to a resealable freezer bag. You can store the pesto in the freezer for up to 3 months! Just thaw it in the fridge overnight before using it in your next baguette sandwich.
What should I do if my cheese isn’t melting properly?
Very! If your cheese isn’t melting as you’d like, ensure you’re using a cheese that melts well, like sharp cheddar or mozzarella. Grate the cheese finely to increase the surface area, aiding in melting. Broiling on high for just 3 to 5 minutes should do the trick, but keep a watchful eye to avoid burning!
Is this baguette sandwich suitable for people with gluten allergies?
I recommend it! While traditional baguettes contain gluten, you can easily make this recipe gluten-free by using gluten-free bread. Just ensure the pesto ingredients are all gluten-free, as some pre-packaged ingredients may contain hidden gluten. Always check labels to be safe!
How long will it take to prepare the pesto from scratch?
Definitely! Preparing the pesto from scratch usually takes about 10 to 15 minutes. Gather your ingredients, blend them together in a food processor until smooth, and you’re ready! It’s a quick and rewarding process that greatly enhances the flavor of your open-faced baguette sandwich.
