- 12 slider buns: Soft, slightly sweet buns that hold everything together without overpowering the fillings.
- 1 lb Italian sausage (sweet or spicy): The star protein, providing rich, seasoned goodness that’s juicy and satisfying.
- 8 oz provolone cheese, sliced: Melts beautifully and adds a mild, creamy layer that complements the sausage perfectly.
- 1/2 cup pesto sauce: Offers fresh herbal brightness and a garlicky punch that really elevates the sandwich.

How to Make Italian Sausage Slider Sandwiches with Pesto, Roasted Red Peppers, and Provolone Recipe
Step 1: Brown the Sausage
Start by cooking your Italian sausage in a skillet over medium heat. Break it up as it cooks so the pieces are bite-sized and browned beautifully. This step is essential because it develops deep, savory flavors and gets rid of any excess fat, ensuring your sliders are rich but not greasy.
Step 2: Prep the Buns and Spread Pesto
While the sausage cooks, slice your slider buns horizontally. Spread a generous layer of pesto sauce on the bottom half of each bun. This pesto is your flavor foundation, infusing the sandwich with herby, vibrant notes that balance the richness of the sausage.
Step 3: Layer with Sausage, Cheese, and Roasted Peppers
Next, pile the cooked sausage onto the pesto-smeared buns, then add slices of provolone cheese right on top. Finally, layer with roasted red peppers for a burst of sweetness and a gorgeous pop of color. This layering creates harmonious textures and flavors in every bite.
Step 4: Assemble and Bake
Put the top bun halves on your loaded sliders, then brush them lightly with olive oil. This little touch guarantees a golden, slightly crisp finish. Cover the sliders with foil and bake at 375°F for about 15 minutes, allowing the cheese to melt perfectly and all the flavors to meld.
Step 5: Finish Baking Until Golden
Remove the foil and bake for another 5 to 10 minutes or until the buns turn a beautiful golden brown. This final step adds a delightful crunch and caramelization on top that takes these sliders to the next level.
How to Serve Italian Sausage Slider Sandwiches with Pesto, Roasted Red Peppers, and Provolone Recipe

Garnishes
For a final flourish, sprinkle fresh basil leaves or a few cracked black pepper grains on top before serving. A light drizzle of extra pesto or a sprinkle of red pepper flakes adds a bit of pizzazz and lets each guest customize their sliders just how they like.
Side Dishes
Pair these Italian Sausage Slider Sandwiches with a simple green salad tossed in lemon vinaigrette or some crispy oven-baked fries for a classic combo. Grilled vegetables or a tangy coleslaw also add a refreshing contrast that complements the richness of the sliders.
Creative Ways to Present
For a party, arrange the sliders on a large wooden board with bowls of extra pesto, roasted peppers, and pickled veggies. You can also skew a few sliders on rustic cocktail picks paired with colorful napkins for an inviting appetizer display that grabs attention.
Make Ahead and Storage
Storing Leftovers
If you have any sliders left over, wrap them tightly in foil or store in an airtight container and refrigerate for up to 3 days. This keeps the flavors trapped and prevents the bread from getting soggy.
Freezing
To freeze, assemble the sliders without baking and wrap them individually in plastic wrap, then place in a freezer-safe bag. They’ll keep well for up to one month. When you’re ready to enjoy, just bake them straight from frozen, adding a few extra minutes on top of the original baking time.
Reheating
Reheat your leftovers in the oven at 350°F for about 10–15 minutes until warmed through and cheese is melty again. Avoid the microwave if you want to keep the bread from getting too chewy or soggy.
FAQs
Can I use turkey or chicken sausage instead of Italian sausage?
Absolutely! Turkey or chicken sausage will work nicely and offer a leaner alternative, but keep in mind the flavor will be milder compared to traditional Italian sausage.
Is it possible to make this recipe vegetarian?
Yes, swap out the sausage for plant-based sausage or seasoned grilled mushrooms to keep that hearty, satisfying feel while making it vegetarian-friendly.
Can I make the pesto from scratch?
Definitely, homemade pesto adds a fresh, customized touch. Blend fresh basil, pine nuts, Parmesan, garlic, and olive oil for a vibrant sauce that’s even better than store-bought.
What type of roasted red peppers should I use?
Roasted red peppers packed in jars are convenient and usually pre-sliced, but you can roast your own fresh bell peppers at home for an extra smoky flavor.
Can I prepare the sliders in advance and bake later?
Yes! Assemble the sliders fully, cover tightly, and refrigerate overnight. Bake just before serving to get that melty cheese and golden top freshly made.
