How to Make Sheet Pan Italian Sausage Sandwiches

Sheet Pan Italian Sausage Sandwiches are a cinch to throw together, especially on busy weeknights. Everything gets roasted together on a single sheet pan for a quick and delicious dinner.

Tools Needed

Ingredients and Substitutions

  • Italian Sausages. You’re looking for fresh, uncooked Italian sausages for this recipe. You can choose hot, sweet, mild, or whichever flavoring most appeals to you!
  • 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.

The Process

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Assemble. Layer a sausage with peppers and onions in a toasted bun and drizzle with the basil aioli. Serve right away.

Tips for Making Sheet Pan Italian Sausage Sandwiches

Here are all my best tips to help you make the most delicious sheet pan Italian sausage sandwiches!

  1. Choose high-quality Italian sausages: Opt for sausages with a blend of spices and herbs to enhance the flavor profile of your sandwiches.
  2. Slice the peppers and onions evenly: Cutting the vegetables into thin, even slices ensures they cook evenly and caramelize beautifully.
  3. 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.
  4. Preheat the baking sheet: This is hugely important as it really helps the sausages sizzle and caramelize.
  5. Arrange ingredients strategically: Place sausages, peppers, and onions in a single layer on the sheet pan to ensure even cooking and caramelization.
  6. Toss and flip halfway through: Gently toss the sausages, peppers, and onions halfway through the cooking time to promote even browning and prevent sticking.

By following these tips, you’ll be well on your way to creating mouthwatering Italian sausage sandwiches that are bursting with flavor. Enjoy the process, get creative with your ingredients, and savor each delicious bite!

Storage & Reheating Instructions

When it comes to storing and reheating Italian sausage sandwiches, here are some best practices to ensure they stay delicious:

  1. Storage: 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.
  2. Reheating the Sausages and Vegetables: 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.
  3. Toasting 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.
  4. Assembly: Once the sausages, vegetables, and bread are reheated, assemble the sandwiches, adding any desired toppings or spreads just before serving.

Italian Sausage Sandwiches FAQs

Can I use different types of sausages for this recipe?

Absolutely! The beauty of Italian sausage sandwiches lies in their versatility. Feel free to experiment with different sausage varieties or even turkey, chicken, or plant-based Italian sausages.

Can I use other vegetables besides peppers and onions?

Definitely! While peppers and onions are classic choices for sheet pan Italian sausage sandwiches, you can certainly get creative with your vegetable selection. Try adding sliced zucchini, mushrooms, or even cherry tomatoes to the mix. Just ensure that the vegetables you choose have similar cooking times to ensure even roasting.

Can I make the sandwiches ahead of time?

While the sausages and roasted vegetables can be prepared in advance, it’s best to assemble the sandwiches just before serving to maintain optimal texture and flavor. However, you can still save time by prepping the ingredients ahead of time and reheating them briefly before assembling your sandwiches.
