Grilled Italian Sausage Sandwich Ingredients
For the Sandwiches
• Italian Sausage Links – Choose hot or mild for your preferred spice level; this is the star of the grilled Italian sausage sandwiches!
• Brioche Rolls – Soft and sturdy, these rolls hold everything together beautifully; substitute with whole-grain or gluten-free for dietary needs.
For the Relish
• Castelvetrano Olives – These sweet and buttery olives create a deliciously unique tang for your relish; can be swapped for any green olives you enjoy.
• Giardiniera – Adds a crunchy, zesty texture to each bite; feel free to use homemade or your favorite store-bought version.
For the Aioli
• Mayonnaise – Acts as the creamy base for your lemon basil aioli; you can lighten it up with Greek yogurt or dairy-free mayo.
• Fresh Basil – This herb brings a refreshing punch to the aioli; dried basil in a pinch won’t quite match its bright flavor.
• Lemon – A must-have for brightness in the aioli; always go for fresh lemons for the best results.
• Garlic – Enhance the depth of flavor in your aioli, adjusting the amount to suit your taste.
• Salt and Pepper – Essential for bringing all the flavors together; adjust according to your taste preferences.
For Cooking
• Cooking Spray – Prevents sticking on the grill; olive oil can be used if you prefer.
Step‑by‑Step Instructions for Ultimate Grilled Italian Sausage Sandwiches
Step 1: Prepare the Grill
Begin by setting up your grill for two-zone cooking: one side for direct heat and the other for indirect. Preheat the grill to medium-high heat, around 400°F, ensuring the grates are clean for optimal grilling. Once ready, lightly spray the grill grates with cooking spray to prevent the sausages from sticking.
Step 2: Make the Relish
In a food processor, pulse together Castelvetrano olives and giardiniera until roughly chopped, creating a vibrant and zesty relish. Aim for a chunky consistency that adds texture to your grilled Italian sausage sandwiches. Once finished, set the relish aside in a bowl to allow the flavors to meld while the sausages cook.
Step 3: Grill the Sausage
Place the Italian sausage links on the indirect heat side of the grill. Cook them for 4–5 minutes, undisturbed, to allow them to brown and develop flavor. Carefully flip the sausages and continue cooking for another 4–5 minutes until their internal temperature reaches 150°F, ensuring they’re perfectly juicy but not fully charred yet.
Step 4: Char the Sausage
Now, move the sausages directly over the heat. Grill for an additional 2–3 minutes on each side until they’re nicely charred with grill marks and the internal temperature hits 160°F. Keep an eye on them—this step gives your grilled Italian sausage sandwiches that irresistible smoky flavor!
Step 5: Toast the Rolls
While the sausages finish, spritz the brioche rolls with cooking spray and place them on the grill grates, cut side down. Toast the rolls for about 1–2 minutes until they’re golden and crisp. Watch closely to prevent burning—the perfect roll adds a delightful crunch to your sandwich.
Step 6: Assemble the Sandwiches
To assemble, place the grilled sausage inside each toasted brioche roll. Generously top with the Castelvetrano-giardiniera relish, letting the tangy and smoky flavors mingle. Finally, drizzle with the creamy lemon basil aioli, adding a refreshing note that completes your ultimate grilled Italian sausage sandwiches.
How to Store and Freeze Grilled Italian Sausage Sandwiches
Fridge: Keep any leftover sandwiches in an airtight container for up to 3 days. To prevent sogginess, store the sausage and rolls separately if possible.
Freezer: Freeze assembled sandwiches wrapped tightly in foil or plastic wrap for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating: To reheat, place thawed sandwiches in a preheated oven at 350°F for about 10-15 minutes or until heated through. This method helps maintain the sandwich’s texture.
Relish Storage: The Castelvetrano-giardiniera relish can be refrigerated in a sealed container for up to 2 weeks. It makes a great topping for other meals too!

Expert Tips for Grilled Italian Sausage Sandwiches
Perfectly Grilled Sausage: Always use an instant-read thermometer to check for doneness—150°F is safe, but char to 160°F for that smoky flavor in your grilled Italian sausage sandwiches.
Rest for Flavor: Allow sausages to rest for a few minutes after grilling. This helps juices redistribute, resulting in a more succulent bite.
Avoid Overcrowding: Give your sausages space on the grill to cook evenly. Overcrowding can cause uneven cooking and prevent those delicious grill marks.
Customize the Relish: Feel free to swap out Castelvetrano olives for your favorite type, but remember, they offer a unique sweetness that pairs wonderfully with the sausage.
Toast with Care: When toasting your brioche rolls, stay close to the grill. A minute can turn from perfect to burnt quickly—aim for golden, not charred!
Double the Batch: If you’re hosting friends, make extra relish! It stores well in the fridge, making it the perfect topping for other dishes too.

Make Ahead Options
These Ultimate Grilled Italian Sausage Sandwiches are perfect for meal prep enthusiasts! You can prepare the Castelvetrano-giardiniera relish up to 3 days in advance, storing it in an airtight container in the refrigerator to keep it fresh and flavorful. The lemon basil aioli can also be made ahead and refrigerated for up to 24 hours; just give it a good stir before serving to reinvigorate the creamy texture. For the sausages, you can grill them ahead of time, then refrigerate them, and simply reheat on the grill for a few minutes before assembling with the toasted brioche rolls.
