Grilled Italian Sausage Sandwiches Ingredients
Get ready to savor every bite of your grilled Italian sausage sandwiches with this essential ingredient list!
For the Sausages
- Fresh Italian Sausage Links – The star of the show, delivering rich, savory flavors; swap for chicken or turkey sausage for a lighter twist.
- Nonstick Cooking Spray – Prevents sticking while grilling; you can also use your favorite oil for a flavorful boost.
For the Rolls
- Brioche Hot Dog Rolls – Soft and slightly sweet, they hold the sausages perfectly; consider whole grain or gluten-free options for variety.
For the Giardiniera Relish
- Castelvetrano Olives – Adds a delicious briny element; green olives work well as a substitute if needed.
- Giardiniera (mild or hot) – Provides a punch of pickled flavor; fresh, chopped vegetables can be an excellent alternative.
- Capers – Enhance the relish with tangy saltiness; feel free to omit them for a milder taste.
For the Lemon Basil Aioli
- Mayonnaise – Creamy base that ties everything together; Greek yogurt is a great lighter substitute.
- Fresh Basil – Gives the aioli an aromatic freshness; swap in parsley if basil is unavailable.
- Lemon – Zesty juice and zest brighten the aioli; lime is an excellent alternative for a citrusy shift.
- Garlic – Infuses depth into the aioli; if fresh isn’t at hand, garlic powder can step in nicely.

Step‑by‑Step Instructions for Grilled Italian Sausage Sandwiches
Step 1: Preheat the Grill
Begin by preheating your grill for two-zone cooking, setting one side for direct heat and the other for indirect heat. If using a gas grill, ignite the burners on one side; for charcoal, pile coals on one side and allow them to ash over for about 15 minutes. This will create an ideal environment for your grilled Italian sausage sandwiches.
Step 2: Prepare the Sauces
While the grill is heating, prepare the zesty lemon basil aioli. Blend together mayonnaise, fresh basil, lemon juice, zest, and minced garlic until smooth. Simultaneously, make the giardiniera relish by pulsing Castelvetrano olives and giardiniera in a food processor until finely chopped, ensuring a vibrant topping for your sandwiches.
Step 3: Grill the Sausage
Once the grill is hot, place the fresh Italian sausage links on the indirect heat side. Close the grill lid and cook them for 4-5 minutes. Use an instant-read thermometer to check for doneness; they should reach an internal temperature of 150°F before you flip them over for even cooking.
Step 4: Char the Sausage
After flipping the sausages, move them to the direct heat side of the grill. Grill them for 2-3 minutes on each side, watching for a nice char to develop, until they reach the recommended internal temperature of 160°F. This crispy finish will elevate your grilled Italian sausage sandwiches.
Step 5: Toast the Rolls
As the sausages finish cooking, spritz the brioche rolls with nonstick cooking spray and place them on the grill. Toast the rolls for about 1 minute, or until they are lightly golden and warm. This step adds a delightful crunch to your sandwiches and a harmonious surface for the toppings.
Step 6: Assemble the Sandwiches
With everything grilled to perfection, it’s time to assemble your ultimate grilled Italian sausage sandwiches. Place the grilled sausage in each toasted brioche roll, generously top with giardiniera relish, and drizzle with the creamy lemon basil aioli. Each bite will be an explosion of flavor that’s sure to please!
