Roast your Peppers & Tomatoes: Preheat your oven to 450° F. Slice the bell peppers into thin strips. Place the red peppers on one baking sheet with half the tomatoes, and place the green on a second baking sheet with the remaining tomatoes. Drizzle each with olive oil, and give a good sprinkle of salt and pepper. Toss with clean hands to combine everything. Pop into the oven and roast for 25-30 minutes, stirring everything halfway through.
Cook the Sausage: While the veggies roast, cook your sausage in a skillet. I like to let it get really deeply browned and crispy on the outside, but cook it however you like it. Drain the grease and pop the meat onto a paper-towel lined plate to rest.
Cook the Pasta: Bring a large dutch oven full of water to a boil. Add a few shakes of salt. Add the rigatoni, and cook as directed on the package. Once it's done, reserve 1/2 cup of the pasta water, and drain the pasta.
Make the Roasted Red Pepper & Tomato Sauce: While the pasta cooks, transfer the pan with the red peppers and tomatoes to the food processor cup of your Oster® 3-in-1 Kitchen System with Texture Select Settings. Add the olive oil, salt, pepper, garlic, and basil. Pulse on medium until you have a nice thick sauce.
Finish the Pasta: Add the roasted red pepper sauce to the now empty dutch oven we used for the pasta. Heat over medium for a few minutes, stirring, just to get the raw garlic flavor out. Then, add the sausage, cooked pasta, veggies, pasta sauce, and parmesan. Stir everything together over medium low heat. Add a splash of heavy cream or reserved pasta water as desired to get things nice and saucy. Taste and add any extra seasoning or more heavy cream or parmesan as desired.
Serve + Store: Serve immediately! Add an extra sprinkle of parmesan on top. Store leftovers in an airtight container in the fridge for 4-6 days.
