Using a Sheet Pan Makes Cleanup a Breeze!

A simple yet elevated weeknight dinner that tastes like hours of prep went into it is my signature recipe move! I’m all about the low-effort, high-reward dinner situations.

There’s something magical about the simplicity of an Italian sausage sandwich. It’s a humble dish that packs a punch, offering a delightful combination of savory and sweet, with just the right amount of spice. I just love sinking my teeth into a perfectly grilled sausage nestled between crusty bread, topped with caramelized peppers and onions.

Whether enjoyed as a quick weekday dinner or a weekend indulgence, these sausage and peppers sandwiches have a way of making every bite feel like a celebration of good food and good company.

Overview of the Key Ingredients

Italian Sausages. You’re looking for fresh, uncooked Italian sausages for this recipe. Whether you prefer sweet, spicy, or fennel-infused sausages, this recipe allows for endless customization. (You can even make these sandwiches vegetarian by using your favorite plant-based sausages!)
Bell Pepper. I’m personally anti-green bell pepper, so I opt for red or yellow peppers (or both!).
Onion. You can use any variety of onion here but I like sweet yellow onions or red onions because they have great flavor when roasted.
Garlic. Whole sliced garlic cloves roasted with the peppers and onions are so good!
Olive oil. Tossing everything with olive oil before roasting gets everything nice and crispy.
Oregano. I love the flavor that the dried oregano gives the sandwich, but you could swap in Italian seasoning or omit completely.
Red Wine Vinegar. A little bit of red wine vinegar creates balance and cuts through some of the fattiness of the sausages.
Basil Aioli. A simple mix of mayo, fresh basil leaves, garlic, lemon zest and juice transforms this sandwich.
Buns. I personally love split-top brioche buns here and always toast them in butter before serving. Use your favorite here, just make sure it’s sturdy enough to hold the sausage and toppings.

How to Make Italian Sausage Sandwiches on a Sheet Pan

Make the basil aioli. “Aioli” sounds so fancy, but it’s really just mayonnaise blended with fresh basil, garlic, lemon juice, and zest. That’s it! If you have a food processor, now’s the time to bust it out.
**The magic step — preheat your baking sheet!** After preheating the oven to 425ºF, pop just the baking sheet inside and let it hang for 10 to 15 minutes. You want it to be screaming hot by the time the sausage, peppers, and onions are added so they start to caramelize upon contact.

Season the sausage, peppers, and onions. Add everything to a large mixing bowl and toss with a little olive oil, oregano, red wine vinegar, salt, and pepper.
Bake. Turn everything onto the hot baking sheet and cook for about 20 minutes. I always flip over the Italian sausage and veggies about halfway through to promote even browning and prevent sticking.

Jenny’s Tip: If after 20 minutes the sausages are cooked but not browned to your liking, place them under the broiler for a couple minutes.

Assemble your sandwiches. Layer a sausage with peppers and onions in a toasted bun and drizzle with the basil aioli.

Jenny’s Tips for Making This Recipe

Choose high-quality Italian sausages. Opt for sausages with a blend of spices and herbs to enhance the flavor profile of your sandwiches.

Slice the peppers and onions evenly. Cutting the vegetables into thin, even slices ensures they cook evenly and caramelize beautifully.

Choose a quality non-stick baking sheet. Since the sausage, peppers, and onions cook directly on the sheet tray opt for a high-quality sturdy baking sheet.

Arrange ingredients strategically. Place sausages, peppers, and onions in a single layer on the sheet pan to ensure even cooking and caramelization.

Prep Time: 10

Cook Time: 20

Total Time: 30

Makes: 4 – 6 servings

Ingredients

Italian Sausage Sandwiches

4-6 uncooked Italian Sausages
1 yellow onion, thinly sliced
2 bell peppers, thinly sliced
4 large garlic cloves, sliced
3 tablespoons olive oil
1 tablespoon red wine vinegar
1 teaspoon dried oregano
4 tablespoons butter, softened
4-6 split-top brioche buns
2 tablespoons chopped Calabrian chilies, for serving

Basil Aioli

1 cup mayonnaise
1/2 cup packed fresh basil leaves
1 garlic clove, sliced
1 teaspoon lemon zest
3 tablespoons fresh lemon juice
kosher salt and pepper

Instructions

Make the basil aioli. Combine all the ingredients in a small food processor and blend until smooth. Season to taste with salt and pepper and refrigerate until ready to use.
Preheat an oven to 425 F.
Preheat a baking sheet. The key to this recipe is preheating a baking sheet in the oven for 10-15 minutes before topping with the sausages, peppers, and onions to really get that sizzle.
Combine sausage, peppers, and onions. In a mixing bowl, toss the sausages, peppers, onions, and garlic with the olive oil, oregano, red wine vinegar, salt, and pepper. Once the baking sheet is hot, carefully spread the sausages and other ingredients in a single layer.
Bake. Return the baking sheet to the oven and bake for 20 minutes, flipping the ingredients halfway through. If the sausages, peppers, and onions need a little more color, switch the broiler on for 3-5 minutes. Remove the sheet pan from the oven.
Toast the buns. While the sausages are in the oven, spread the sides of the buns with softened butter and toast in a nonstick skillet until golden brown.
Assemble. Layer a sausage with peppers and onions in a toasted bun, add chopped Calabrian chilies, and drizzle with the basil aioli. Serve right away.

Storage Instructions

To store: If you have leftover assembled sandwiches, it's best to disassemble them before storing. Keep the sausages, roasted vegetables, basil aioli, and bread separately in airtight containers in the refrigerator. This helps maintain the texture and freshness of each component. All the components should last 4-5 days in the fridge.
To reheat the filling: When ready to enjoy your leftovers, reheat the sausages and vegetables in a preheated oven at around 350°F (175°C) for about 10-15 minutes or until warmed through. You can also heat them in a skillet over medium heat with a splash of olive oil, tossing occasionally until heated evenly.
To reheat the bread: To refresh the bread and add a touch of crispness, toast it lightly in a toaster, toaster oven, or under the broiler for a few minutes. This step will ensure that the bread doesn't become soggy.
Once the sausages, vegetables, and bread are reheated, assemble the sandwiches, adding any desired toppings or spreads just before serving.
