Fill a large pot with water and add a generous pinch of salt. Bring to a rolling boil over high heat, add the penne pasta, and cook until al dente according to package instructions, typically 10-12 minutes. Just before draining, reserve 60 ml of pasta water, then drain and set pasta aside.

While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the Italian sausage, breaking it into small pieces. Cook for 6-8 minutes, occasionally stirring, until fully browned and cooked through. Remove sausage to a paper towel-lined plate, leaving a small amount of fat in the skillet.

In the same skillet, add sliced red and yellow bell peppers along with diced onion. Sauté over medium heat for 5-7 minutes, stirring occasionally, until vegetables are just tender and the onion turns translucent. Stir in minced garlic and cook for 1-2 minutes until fragrant, avoiding browning.

Return the cooked sausage to the skillet with the vegetables. Add crushed tomatoes and gently mix to combine. Pour in reserved pasta water gradually, stirring to achieve your preferred sauce consistency. Simmer over medium-low heat for 5-10 minutes, allowing flavors to blend. Season with salt and black pepper to taste.

Add the drained penne pasta to the skillet. Toss thoroughly with the sausage and bell pepper sauce until evenly coated. Allow to cook together for 1-2 minutes to absorb flavors.
