February 07, 2023

Are you looking for a fun game day treat? Try my Loaded Supreme Pizza Sliders! They’re packed with all the best pizza elements, including pepperoni, zesty sauce, and gooey cheese. These tasty sandwiches come together in less than an hour, perfect for parties.

Traditional sliders are fantastic, but these sandwiches take on a new flavor when cooked on the Traeger Timberline 1300. These sliders will be a hit with adults and kids alike! Serve them for your Super Bowl parties, tailgating, or fun weeknight meal. Sliders are a universally friendly dinner everyone loves. They’re easy to eat and don’t require any fancy ingredients. I’ve tried several slider recipes, but I must admit, this is one of the best. With a wide variety of components, you have an entire meal in the palm of your hand.

The Ingredients

The best thing about this recipe is that you can customize it to fit your family’s needs. If you have leftover veggies in the fridge, add them to the sauté pan! Here’s what you need to add to your shopping cart.

Italian sausage and pepperoni. Italian sausage gives these sliders a little spice. I used Italian sausage bratwurst, taken out of the casing and broken down. You can also use ground Italian sausage if desired. I wanted my Loaded Supreme Pizza Sliders to have two types of meat, so I also added a lot of mouth-watering pepperoni.
Veggies. Supreme pizza has loads of veggies, so I added bell pepper, onion, and mushrooms. These veggies are a great starting point, but you can use whatever makes your heart happy.
Heath Riles BBQ Garlic Butter Rub. This tasty rub feature multiple garlic notes and a hint of heat on the back end. I use it on veggies, popcorn, eggs, fish, chicken, and anything else that could use a boost! Once you try it, you’ll never be without it.
Hawaiian rolls. Sliders and Hawaiian rolls are a winning combination! These soft, sweet buns pair well with savory ingredients. They crisp beautifully in the oven or the pit.
Bobby T’s Pizza Sauce. This delicious sauce comes from my good friend Bobby T. It’s inspired by his Italian grandma’s recipe. It features crushed tomatoes, herbs, and olive oil for an authentic taste.
Mozzarella cheese. You can’t have pizza without mozzarella cheese! Cheese adds a delicious texture to the Loaded Supreme Pizza Sliders and creates a barrier for the sauce. I added lots of cheese to my sandwiches, but you can adjust the quantity.
Bobby T’s Pizza Seasoning. I can say from experience that this is the best pizza seasoning. It contains a secret blend of herbs that have an authentic Italian flavor. You can use it in your pizza dough, sauce, or to top sliders, as I did.

The Smoker Setup

Here’s the main setup I used for this cook. You can find more of my grilling favorites in the Equipment and Tools section.

Pellet grill/smoker. I used a Traeger Timberline 1300 for this cook. This pit is incredible because you can use it to grill or smoke. The Traeger Timberline 1300 has many excellent features, like a pellet sensor, a super smoke button, and easy transportation.
Charcoal. I stoked the pit with Royal Oak Charcoal Hardwood Pellets and Royal Oak Tumbleweeds. This combination burns hot and fast. I use these pellets often with great results! Royal Oak Charcoal is an excellent brand of clean charcoal without any fillers.

The Process for Making Loaded Supreme Pizza Sliders

You can find a detailed demonstration of this recipe in the video and recipe card. For now, here’s a quick rundown of my cooking process.

Fire up the Traeger Timberline 1300. I stoked the Traeger Timberline 1300 with Royal Oak Charcoal Hardwood Pellets and Royal Oak Tumbleweeds. Then, I fired it up to 350℉.
Cook the sausage. I let a cast-iron skillet preheat for 15 minutes on the pit. I added olive oil to the pan, then took my Italian sausages out of the casing and into the skillet. I mashed the sausage into small pieces, then browned it.
Add veggies. I added the sliced onion, pepper, and mushrooms to the pan and mixed them with the veggies. I seasoned the mixture with Heath Riles BBQ Garlic Butter Rub, then let it cook for 10 minutes.
Melt the butter. I removed the meat and veggies from the Traeger Timberline 1300 and let them cool. Then, I placed the butter in a small skillet and let it melt on the pit while I assembled the sliders.
Assemble the bottom layer. I cut the Hawaiian rolls in half to assemble my sliders, so there’s a top and bottom bun. I placed the bottom layer in an aluminum pan to keep it steady. Then, I added a little Bobby T’s Pizza Sauce and a handful of shredded mozzarella cheese. I topped the cheese with a good sprinkle of Heath Riles BBQ Garlic Butter Rub and Bobby T’s Pizza Seasoning.

Add veggies and sausage. Next, I used a slotted spoon to pile on the sausage and veggies. To finish the sliders, I added pepperoni and a little more cheese. I spooned more pizza sauce on the top bun, then flipped it onto my bottom layer. I took the butter off the grill and brushed it over the top. The cherry on top was a little more Heath Riles BBQ Garlic Butter Rub and Bobby T’s Pizza Seasoning.
Cook the sliders. I placed the sliders on the Traeger Timberline 1300 and let them cook for 20 minutes. Pro tip: If your rolls are browning too fast, tent them with tin foil. This slows down the browning process.
Serve. I took the rolls off the grill, then let them cool. The only thing left was to dig in!

The Results

The Loaded Supreme Pizza Sliders were gooey, crisp, and flavorful. This sandwich was like a mini supreme pizza! These sliders are sure to impress anyone.
